Our experience with the arterial switch operation for transposition of the great arteries has confirmed the attainability of excellent results with elective neonatal surgery. Up to this time, we have repaired tetralogy of Fallot during the neonatal period only when symptoms, either severe persistent cyanosis or cyanotic spells, have been present. This review assesses the results of such nonelective neonatal correction of tetralogy between 1973 and 1988. Twenty-seven neonates with either symptomatic tetralogy of Fallot or symptomatic tetralogy of Fallot with valvar pulmonary atresia underwent repair. Mean age at repair was 8 +/- 8.4 days and mean weight was 3.0 +/- 0.7 kg. Unsatisfactory palliative shunts had previously been placed elsewhere in four patients. Twenty-five transannular patches and two conduits were used for reconstruction of the right ventricular outflow tract. There were five deaths in the hospital, three of which were due to avoidable technical problems. All deaths occurred in patients with pulmonary artery (Nakata) index less than 150 mm2/m2. One premature child weighing 2.3 kg displayed an absent pulmonary valve-like syndrome after repair and died late of respiratory complications caused by aneurysmal branch pulmonary arteries. Actuarial survival at 5 years was 74%. There was a single rapidly declining hazard phase for death, with the hazard approaching zero at 1 1/2 years after repair. Actuarial freedom from need for reoperation was 76% at 5 years. Postoperative catheterization of 15 long-term survivors showed right ventricular pressure less than 70% systemic in 13 cases. All patients are symptomatically well and functioning in sinus rhythm 1 to 15 years after repair (mean, 5 +/- 4 years). This experience with neonates with symptoms suggests that, if mortality is lower in the absence of symptoms, elective repair of tetralogy of Fallot could be reasonably undertaken during the first months of life. 相似文献

Anomalous origin of the left anterior descending coronary artery from the right coronary artery can interfere with the location of the usual ventriculotomy during repair of tetralogy of Fallot. The purpose of this study was to compare the results of two operative techniques: (1) a "tailored" right ventricular incision and outflow patch reconstruction and (2) placement of a conduit from the right ventricle to the main pulmonary artery. We reviewed the records of 416 patients who had complete repair of tetralogy of Fallot at the Mayo Clinic from 1973 through 1984. Twenty (5%) (median age 6.5 years) had anomalous origin of the left anterior descending coronary artery from the right coronary artery. Twelve of these patients had right ventricular outflow patch reconstruction, and eight had placement of a conduit from the right ventricle to the pulmonary artery. Three deaths occurred, all during hospitalization, two in the patch reconstruction group and one in the conduit group. The average reduction in right ventricular pressure postoperatively was slightly but not significantly greater for the conduit group. These data indicate that correction of tetralogy of Fallot with anomalous origin of the left anterior descending coronary artery can be done with either patch reconstruction or conduit placement. Selection of the more appropriate procedure depends on the exact location and degree of tortuosity of the anomalous artery and the level and severity of right ventricular outflow obstruction. 相似文献

Sixteen of 18 patients undergoing intracardiac repair of tetralogy of Fallot following ascending aorta-to-right pulmonary artery shunt procedures required patch reconstruction of the right pulmonary artery because of significant obstruction at the site of the shunt. Patch reconstruction was required in all patients having had shunts done at less than 1 year of age. The operative mortality in this group of patients was higher than that in patients undergoing repair of tetralogy alone or repair plus ligation of a prior Blalock-Taussig shunt, but it was lower than that associated with repair plus obliteration of a previous Potts anastomosis. The ascending aorta-to-right pulmonary artery shunt appears to be the best procedure for palliation of severely symptomatic infants with tetralogy in whom the anatomy is not suitable for either primary repair or a subclavian-to-pulmonary artery shunt. Cardiac catheterization and angiocardiography should be performed prior to subsequent total correction to demonstrate the direction of flow and the anatomical configuration of the right pulmonary artery. 相似文献

OBJECTIVE: To assess the results of a staged surgical approach for tetralogy of Fallot with pulmonary atresia, hypoplastic or absent pulmonary arteries, and major aortopulmonary collateral arteries. METHODS: We retrospectively reviewed a consecutive series of these patients from a single institution. RESULTS: From July 1993 to April 2001, 46 consecutive patients with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collateral arteries were treated with staged surgical repair. The operative sequence usually began with a central aortopulmonary shunt followed by unifocalization of aortopulmonary collateral arteries depending on the source and distribution of pulmonary blood flow. Twenty-eight patients (61%) subsequently underwent complete repair with ventricular septal defect closure and right ventricle to pulmonary artery connection. Those patients who underwent complete repair had a median of 3 total operations (range 1-6). The ratio of the mean pulmonary artery pressure to the mean systemic blood pressure at the time of complete repair was 0.36 (range 0.19-0.58). Two of the 28 repaired patients (7.1%) required subsequent fenestration of the ventricular septal defect closure due to later development of supersystemic right ventricular pressure and right ventricular failure. Eighteen patients (39%) have undergone 1 or more staging operations and are considered good candidates for eventual complete repair. There were no hospital deaths. There was 1 late death (2.2%; 95% CI 0.4-11.3%) in a patient born prematurely who developed severe bronchopulmonary dysplasia precluding complete repair. CONCLUSIONS: For tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries, a staged surgical approach yields low overall mortality and acceptable hemodynamics after complete repair. 相似文献

To evaluate the growth of a pulmonary trunk reconstructed without an extracardiac conduit, the hemodynamics and diameter of a new pulmonary trunk were measured in 5 patients from the right ventriculogram and MRI at postoperative follow-up periods. There were tetralogy of Fallot with pulmonary atresia in two patients, tetralogy of Fallot with single coronary in one, truncus arteriosus type I in one and transposition of the great arteries with ventricular septal defect and pulmonary stenosis in one. The age at operation ranged from 26 days to 4.5 years. The posterior wall continuity of the right ventricle and pulmonary artery was established by the direct pulmonary-right ventricular anastomosis in three patients and by the interposition of the left atrial appendage in two. Postoperative follow-up periods ranged from 2 years and 6 months to 3 years and 10 months (median: 2 years and 11 months). In four of them, the postoperative right ventricular to aortic or left ventricular systolic pressure ratios were less than 0.4 without any significant systolic pressure gradients between pulmonary artery and right ventricle. In these four patients, the diameters of the reconstructed pulmonary trunks grew from 10~18 mm to 18~21 mm postoperatively. These diameters were more than 100% of normal values. In the remaining patient with tetralogy of Fallot and single coronary artery, the obstruction of the new pulmonary trunk by a bulged left atrial appendage, which was used as the postoperior wall, was observed on the right ventricular outflow tract reconstruction without an extracardiac conduit has growth potential in the future. 相似文献

To aid preoperative decision-making, we have related the ratio of postrepair peak pressure in the right and left ventricles (PRV/LV) to preoperative cineangiographic measurements in a retrospective study of 135 patients undergoing complete repair of tetralogy of Fallot or tetralogy of Fallot with pulmonary atresia. Postrepair PRV/LV was related to the preoperative diameter of right (DRPA) and left (DLPA) pulmonary arteries normalized to the descending thoracic aorta (DescThAo) in patients undergoing repair with transannular patching or a valved external conduit by the dquation: PRV/LV = 0.4840/(DRPA/DescThAO + DLPA/DesThAo) + 0.2007. Stenosis of the right pulmonary artery orifice and pulmonary artery arborization abnormalities incrementally increased postrepair PRV/LV. When a transannular patch was not used in classical tetralogy of Fallot, an increment of postrepair PRV/LV usually resulted, depending upon the size of the "anulus" measured intraoperatively: Incremental PRV/LV = 0.09437 . exp(-0.6344 . Z) where Z is a normalized expression in circumference terms of the diameter of the pulmonary arterial outflow tract (DPAOT) measured intraoperatively after infundibular dissection and valvotomy. DPAOT is itself related to the cineangiographically measured pulmonary valve anulus diameter (DPVA): DPAOT = 3.357 . DPVA0.5789 . BSA0.1551. In toto, these relations allow postrepair PRV/LV without transannular patching to be estimated from preoperative cineangiographic measurements. This allows preoperative predictiom in classical tetralogy of Fallot of the need for transannular patching, and in infants this can determine the choice between primary one-stage repair and two-stage repair. Prediction of postrepair PRV/LV when transannular patching or an external conduit is planned allows identification of patients in whom right and left pulmonary arteries are too small for safe complete repair, and in them an initial palliative operation should be done to enlarge the arteries. 相似文献

Tetralogy of Fallot: favorable outcome of nonneonatal transatrial, transpulmonary repair. 总被引:4,自引:0,他引:4
This report describes our experience with 366 patients who had a transatrial, transpulmonary repair of tetralogy of Fallot between December 1980 and December 1991. Included in this group are patients with tetralogy of Fallot plus atrioventricular septal defect as well as patients displaying all degrees of aortic override (in the presence of subaortic ventricular septal defect and right ventricular outflow tract obstruction). Median age was 15.3 months and median weight, 12.3 kg. Of the 366 patients, 72% required a pericardial patch to reconstruct the main pulmonary artery or right ventricular outflow tract. Serious coronary anomalies were seen in 11 patients, without influencing surgical approach. There were two hospital deaths (0.5%; 70% confidence limits, 0.2% to 1.2%). Actuarial survival was 97.5% at 42 months (95% confidence limits, 95% to 99%) reflecting four late deaths over 1,129 patient-years of follow-up. Postoperative cardiac catheterization studies were performed in 61 patients at a mean follow-up interval of 23 months. Mean right ventricular/left ventricular systolic pressure ratio after repair was 0.46 (standard deviation, 0.28), and mean gradient across the right ventricular outflow tract was 15 mm Hg (standard deviation, 24 mm Hg). Actuarial freedom from reoperation for any reason has been 95% (95% confidence limits, 92% to 97%) at 5-year and 10-year follow-up. These early and medium-term results encourage us to continue with transatrial, transpulmonary repair of tetralogy of Fallot. We believe that this approach has an operative risk similar to or lower than transventricular repair, and that it will result in better preservation of right ventricular function in the long term. 相似文献

Total correction of tetralogy of Fallot was performed without a ventriculotomy in 39 patients aged 8 months to 39 years (mean age, 9.1 years) between May 1984 and July 1988. A transatrial approach was used to resect the obstructed infundibulum and to close the ventricular septal defect. In 14 patients, the pulmonary annulus was not enlarged (group 1). Twenty-five patients required a transannular patch (group 2), placed by extending the pulmonary artery incision 1 cm into the right ventricular infundibulum. Eleven patients had repair of pulmonary artery branch stenosis, and associated intracardiac anomalies were simultaneously corrected in 10 patients. After repair, the right ventricular to left ventricular systolic pressure ratios ranged from 0.36 to 0.59 (mean ratio, 0.45) in group 1 and 0.33 to 0.70 (mean ratio, 0.51) in group 2. There were no hospital or late deaths in group 1. Two patients in group 2 with a small left ventricle died shortly after operation. The 37 survivors were followed for 2 to 51 months. Postoperative catheterization in 7 patients detected no residual ventricular septal defects, mild pulmonary regurgitation in 2 patients (group 2), and right ventricular to left ventricular pressure ratios ranging from 0.25 to 0.42 (mean ratio, 0.34). Only 1 patient with a previous total repair by ventriculotomy is symptomatic and requires antiarrhythmic agents and diuretics. The other 36 patients are asymptomatic. In conclusion, tetralogy of Fallot can be safely repaired at any age without a ventriculotomy. The results indicate a minimal incidence of postoperative arrhythmias and pulmonary regurgitation, as well as improved right ventricular function. 相似文献

OBJECTIVE: The purpose of this study was to review our results with an approach of early primary repair for tetralogy of Fallot or double-outlet right ventricle with anomalous coronary arteries, using several techniques to minimize the use of a conduit. METHODS: Twenty consecutive neonates and infants with anomalous coronary arteries crossing an obstructed right ventricular outflow tract underwent primary repair. Median age was 5.5 months and mean weight 6.22 kg. The anomalous coronary arteries included the left anterior descending from the right coronary artery (n = 10), the right coronary artery from the left anterior descending (n = 1), the left anterior descending from the right sinus (n = 1), and a significant conal branch from the right coronary artery (n = 7) or left anterior descending (n = 1). Two neonates had pulmonary atresia. The right ventricular outflow tract was reconstructed without a conduit in 18 patients, including those with pulmonary atresia. Surgical techniques included main pulmonary artery translocation in 4 patients, transannular repair under a mobilized left anterior descending coronary artery in 2 patients, and displaced ventriculotomy with subcoronary suture lines in 8 patients. In 4 patients the right ventricular outflow tract was repaired via the ventriculotomy and/or pulmonary arteriotomy. A homograft was used as the sole right ventricle-pulmonary artery connection in 1 patient and in another a homograft was added to a hypoplastic native pathway. RESULTS: There have been no early or late deaths. The right ventricular/left ventricular pressure ratio within 48 hours of the operation was 0.47 +/- 0.10. There were 2 reoperations at 8 and 11 years after the operation, during a mean follow-up of 5.2 years (1-11.3 years). CONCLUSIONS: Primary repair of tetralogy of Fallot or double-outlet right ventricle with anomalous coronary arteries can be done in neonates and infants with excellent results. Alternative surgical techniques for right ventricular outflow tract reconstruction, such as main pulmonary artery translocation, can avoid the use of a conduit in most patients. 相似文献

Eleven patients underwent late repeated correction of tetralogy of Fallot in 1991–1993. The previous operation was repair of simple Fallot's tetralogy in seven cases, repair plus transannular patch in one case and repair of tetralogy and pulmonic atresia in three cases. The indications for reoperation were residual ventricular septal defect, right ventricular outflow tract (R.V.O.T.) obstraction, residual branch pulmonary artery stenosis, aneurysmal dilatation of R.V.O.T. Patch or combination of any of the above. At reoperation these defects were corrected. The post operative course was uneventful in eight patients. Two required mechanical ventilation for 2-3 days, and one underwent another operation for residual branch pulmonary artery stenosis. The functional and haemodynamic results were good in ten patients, and one had residual distal pulmonary artery stenosis. There were no death during 2 years of follow-up. Repeated correction of tetralogy of Fallot thus had low postoperative morbidity and good haemodynamic results. For the relatively few patients initially found to have tetralogy of Fallot and pulmonic atresia, the outcome may be less favorable. 相似文献

We present an unusual combination of lesions in an 8-month-old child diagnosed with tetralogy of Fallot, anomalous origin of right pulmonary artery, and anomalous coronary artery crossing the pulmonary annulus. The association of anomalous origin of branch pulmonary artery from aorta and tetralogy of Fallot (TOF) is extremely rare with an incidence of 0.4%. The incidence of anomalous coronary artery in TOF is 10.3%. However, a combination of all three lesions poses challenges to surgical repair and has not been previously reported. 相似文献

A 55-year-old man with tetralogy of Fallot successfully underwent correction using a valved conduit. He was diagnosed as having
congenital heart disease during childhood, but no surgical intervention was performed. Cyanosis and dyspnea on effort had
progressed gradually. Catheterization showed a left ventricular end diastolic volume of 126 ml, and the pulmonary arteries
had sufficient diameters. To prevent postoperative pulmonary regurgitation, we planned to use a bioprosthetic valved conduit
for right ventricular outflow tract reconstruction. At 4.5 years after the operation he is in New York Heart Association functional
class I. The catheterization performed 1.5 years after the surgery showed no pressure gradient between the right ventricle
and the pulmonary artery. Thus, total correction of tetralogy of Fallot in an adult can be achieved safely, and the use of
a bioprosthetic stented valved conduit can be beneficial. 相似文献

Transatrial-transpulmonary repair of tetralogy of Fallot 总被引:3,自引:0,他引:3

Classical tetralogy of Fallot was repaired by a transatrial-transpulmonary approach in 61 of 70 patients treated surgically on one surgical service between July 1981 and December 1985. Their ages ranged from 2.5 months to 57 years (mean 52.9 +/- 104.2 months). The ventricular septal defect was closed through the right atrium and tricuspid valve in 60 patients and via the pulmonary artery in one patient with a subpulmonary defect. A pulmonary arteriotomy was made in 38 patients to expose the stenotic pulmonary valve for valvotomy and to begin the infundibular mobilization and resection. It was extended through a small pulmonary anulus primarily in 15 patients and secondarily in one, a minimal distance upon the right ventricular infundibulum to enlarge the outflow tract to 2 standard deviations larger than the mean normal pulmonary valve anulus diameter. There were no hospital or late deaths or reoperations among the entire group. The mean postrepair peak right ventricular/left ventricular pressure measured in the operating room was 0.52 +/- 0.165 for the entire group of 61 patients which indicates similar relief of pulmonary stenosis to that obtained by the classical transventricular repair. At follow-up between 2.3 and 53.8 months (mean 22.6) each patient was in New York Heart Association Class I and without cardiac medication. Postoperative cardiac catheterization studies performed in nine patients between 4 and 28 months after operation showed no residual ventricular septal defects and a mean peak right/left ventricular pressure of 0.42 +/- 0.13. This series indicates that successful repair of tetralogy of Fallot can be accomplished in most patients by a transatrial-transpulmonary approach, which may provide improved right ventricular function over the long term. 相似文献

Placement of a right ventricle-pulmonary artery conduit (18- or 20-mm grafts) made of Gore-Tex without a prosthetic valve was undertaken in 6 patients ranging in age from 8 1/2 to 32 years. Three patients had tetralogy of Fallot with pulmonary atresia, and the other 3 had transposition of the great vessels, ventricular septal defect, and pulmonary obstruction. Pulmonary pressure was low in all patients. The technique for implantation of this valveless, noncrimped type of prosthesis is described. 相似文献

Twenty-one patients underwent elective hemodynamic and cineangiographic studies 1 to 9 years after repair of tetralogy of Fallot and pulmonary atresia. They were a subset of 41 patients who underwent complete repair between Jan. 1, 1973, and 1988. The mean and systolic pulmonary arterial pressure, as well as the pulmonary vasculature resistance, were abnormally high in 60% of the patients. Thirty-three percent of the patients were found to have pulmonary arterial segments that were not connected to the central and unbranched hilar portions of the right and left pulmonary arteries. The mean pulmonary artery pressure and the pulmonary vasculature resistance were correlated (inversely) with the number of centrally connected pulmonary arterial segments. The pulmonary vasculature resistance per pulmonary arterial segment was also inversely correlated with the number of centrally connected pulmonary arterial segments. Inferences: The finding that abnormalities in the pulmonary vasculature of centrally connected pulmonary arterial segments become more severe as the number of centrally connected pulmonary arterial segments decreased has implications as to hemodynamic effectiveness of unifocalization operations. Since others have found these abnormalities in the pulmonary vasculature to be age related, the findings support beginning the appropriate surgical treatment of patients with tetralogy of Fallot and pulmonary atresia very early in life. 相似文献

The case history of an infant with tetralogy of Fallot who had a Waterston anastomosis performed at the age of 1 year is presented. Subsequent chest roentgenograms revealed a ringlike calcification which was shown at angiography and operation to be due to a false aneurysm of the right pulmonary artery at the site of the Waterston anastomosis. The aneurysm also produced unidirectional obstruction of the right pulmonary artery. A review of the literature suggested that a false aneurysm of the right pulmonary artery after a Waterson anatomosis had not been reported previously. 相似文献

OBJECTIVES: Patients with tetralogy of Fallot and diminutive pulmonary arteries are at risk for suprasystemic right ventricular pressure and right ventricular failure after complete repair. We report the short-term outcome and medium-term follow-up after using a fenestrated ventricular septal defect patch as a component of staged repair in selected patients. METHODS: We reviewed 47 patients with tetralogy of Fallot and diminutive pulmonary arteries whose ventricular septal defect patch was fenestrated, either electively or as a rescue technique, at a single institution between 1984 and 2001. RESULTS: Early mortality was 10.6% and occurred only in patients who underwent rescue fenestration. Review of medium-term follow-up (median, 39 months) revealed 4 late deaths; an additional 4 patients experienced right ventricular failure despite fenestration. Most (7/8) of these late events occurred in patients who underwent planned fenestration. Excessive left-to-right shunt through the fenestration developed in only 2 patients. CONCLUSIONS: Fenestrated patch closure of the ventricular septal defect in patients with tetralogy of Fallot and diminutive pulmonary arteries resulted in 10.6% early mortality. Used preemptively in selected patients, this technique is associated with no surgical mortality and a low incidence of excessive left-to-right shunt (4%). Early survivors remain at risk for late death and right ventricular failure despite fenestration. 相似文献
