BACKGROUND: A retrospective analysis of the mortality, morbidity and long-term follow-up of patients undergoing corrective surgery for ventricular septal defect and congenital mitral valve disease is presented. METHODS AND RESULTS: Between January 1991 and December 2000, 69 consecutive patients aged 2 months to 45 years (median 18 months) underwent repair of ventricular septal defect and associated mitral valve disease. In 52 patients (75%), the ventricular septal defects were located in the perimembranous and subarterial area. Forty-six patients had congenital mitral incompetence and 23 had congenital mitral stenosis. The ventricular septal defect was repaired through the right atrium in all. Sixty-five patients underwent reconstruction of the mitral valve and 4 underwent primary mitral valve replacement. Another 4 patients underwent mitral valve replacement after a failed repair. Associated procedures included: patent ductus arteriosus ligation (n=12), aortic valve replacement (n=6), coarctation repair (n=13), interrupted aortic arch repair (n=1), atrial septal defect closure (n=17) and Takeuchi repair (n=1). There were 6 early deaths (8.6%). Three deaths were due to pulmonary arterial hypertensive crisis and one due to residual mitral stenosis. One death was due to intractable congestive heart failure. Another patient died due to persistent low cardiac output. Follow-up ranged from 6 months to 120 months (mean 64.4+/-33.6 months). Reoperation was required in 22 patients, mainly for recurrent/residual mitral valve dysfunction or hemodynamically significant left ventricular outflow tract obstruction. There were 4 late deaths, 2 due to residual mitral stenosis and the other 2 as a result of a thrombosed prosthetic valve. At 10 years, the actuarial survival rate was 850+/-5.0%, and freedom from reoperation was 45%+/-10.0%. CONCLUSIONS: Reconstruction of the mitral valve along with closure of VSD is possible in most cases. However, careful follow-up is recommended to detect changes in the mitral valve status over a course of time.  相似文献

 A female neonate with mitral stenosis due to accessory mitral valve with ventricular septal defect and patent ductus arteriosus is described. She was referred to our hospital because of neonatal asphyxia. Asphyxia was improved by ventilator support, but rapid deterioration of respiration with pulmonary congestion and hemorrhage appeared 8 days after birth. Echocardiography revealed an accessory mitral valve attached to the anterior mitral leaflet with a perimembranous ventricular septal defect and patent ductus arteriosus. Although there were no echocardiographical findings indicating mitral stenosis on admission, the mitral stenosis blood flow patterns were detected by color and pulsed Doppler examination performed on the eighth day after admission. Transaortic resection of accessory mitral valve tissue was performed with patch closure of the ventricular septal defect and ligation of the ductus arteriosus 35 days after birth. After operation, pulmonary congestion and hemorrhage were improved. Postoperative echocardiography showed complete resection of the accessory mitral valve and no mitral insufficiency. We concluded that the combination of the accessory mitral valve and left-to-right shunt due to ventricular septal defect or patent ducturs arteriosus might have led to a critical hemodynamic condition due to relative mitral stenosis in the neonatal period with the decrease in pulmonary vascular resistance.

The case reported here is the tenth showing aortic atresia associated with the usual combination of defects (mitral stenosis, left ventricular hypoplasia, stenosis of ascending aorta and arch, patent foramen ovale, right ventricular and pulmonary artery dilatation and hypertrophy, enlarged ductus arteriosus, and nonpatent interventricular septum). Six additional cases in the literature show grave congenital defects (absent septums; transposition of aorta) associated with aortic atresia, making this the sixteenth recorded case of congenital aortic valvular atresia.  相似文献

Shone syndrome is a rare and complex congenital heart disease. It is characterized in its complete form, by a constellation of the four potentially obstructive lesions of the left heart side. Incomplete Shone's complex includes 2 or 3 of the characteristic lesions which, include a supravalvular mitral membrane, valvular mitral stenosis (MS) by a parachute mitral valve (PMV), subaortic stenosis and aortic coarctation (Coa). We describe here, the case of a 35-year-old man, hospitalized for chronic dyspnea and in whom, the diagnosis of incomplete Shone's complex is retained by echocardiographic analysis. Observed lesions include a parachute mitral valve responsible for mild regurgitation and moderate mitral stenosis, bicuspid aortic valve, and pseudo interruption of the aorta with dilatation of the ascending aorta and a patent ductus arteriosus. This case is the 2nd on 3942 patients in Drighil congenital heart disease registry.  相似文献

From 1965 to 1981, 27 patients over 35 years of age were operated for isthmic coarctation of the aorta. Surgery consisted of resection and direct suture in 16 cases, implantation of a Dacron prosthesis in 7 cases, isthmoplasty in 1 case, aortotomy-graft in 1 case, insertion of a Dacron tube between the left subclavian artery and the descending thoracic aorta in 1 case; finally, one patient presented with a rare form of coarctation in a double aortic arch and was treated by a bypass from the brachiocephalic trunk to the descending thoracic aorta. Ten patients had associated pathology. This was treated at the same time in 4 cases: closed heart mitral commissurotomy, cardiac plexectomy, section-suture of patent ductus arteriosus, and a resection of aneurysms of four intercostal arteries. A Bjork aortic valve prosthesis had been inserted nine months previously in a women with calcific aortic stenosis. There were 2 deaths (7,4%) in the immediate postoperative woman with calcific aortic stenosis. There were 2 deaths (7,4%) in the immediate postoperative period (one acute pulmonary oedema, one pulmonary embolism). There has been no operative mortality in the last 10 years. Twenty-three of the 25 survivors have been followed-up for an average period of 91,5 months (range 1 to 18 years). Two patients died of cardiovascular causes. Analysis of these results show: that the mortality rate is not prohibitive compared to that of the natural history of the condition (the average survival rate of unoperated patients is 35 years), good secondary results despite frequent technical difficulties, the possibility of residual hypertension (especially in older patients) which responds well to drug therapy.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

The 2-dimensional echocardiographic features of interruption of the aortic arch are presented based on analysis of the echocardiograms and angiograms from 8 infants: 2 with type A and 6 with type B interruption. Each infant had a patent ductus arteriosus, 6 had a conoventricular septal defect with leftward deviation of the conal septum, 1 had truncus arteriosus with truncal valve stenosis, and 1 had a distal aortopulmonary septal defect with an intact ventricular septum. Echocardiographic images obtained from the suprasternal notch or from a high parasternal approach demonstrated the interruption of the aortic arch and continuation of the patent ductus arteriosus into the descending aorta. These findings were compared with those in infants with aortic atresia and a hypoplastic ascending aorta or discrete coarctation of the aorta with tubular hypoplasia of the aortic arch. Types A and B interruption of the aortic arch were easily differentiated and the caliber of the patent ductus arteriosus was assessed. The characteristic conoventricular septal defect was readily visualized from an apex 2-chamber view or from a subcostal sagittal plane view. With this information subsequent angiography can be more expeditiously performed in this group of critically ill infants.  相似文献

Twenty-five infants under 1 year of age (mean weight 3.4 kg) underwent repair of coarctation of the aorta between the years 1965 and 1982. Three patients had coarctation only, three had coarctation with patent ductus arteriosus (PDA), and 19 had associated intracardiac anomalies. Eleven patients underwent resection of the aorta and end-to-end anastomosis. Eight had subclavian flap arterioplasty, five had patch graft arterioplasty, and one had subclavian-to-aortic anastomosis. Additional procedures were performed on seven patients: banding of the pulmonary artery on one, repair of total anomalous pulmonary venous drainage on one, mitral valve replacement on one, aortic valvotomy on one, and aortic valvotomy plus pulmonary artery banding on one. Twenty-one survived the operation. All patients who died had associated intracardiac anomalies. The 21 survivors have been followed from 3 months to 13 years, with three late deaths that were associated with intracardiac anomalies. Five of the survivors underwent additional second operations: one had repair of the re-coarctation, one had replacement of the prosthetic mitral valve, one had aortic valvotomy, and two had pulmonary artery debanding and closure of a ventricular septal defect. Two of the 18 surviving patients have mild hypertension associated with a residual gradient. The others are in good health.  相似文献

To assess the accuracy of 2-dimensional (2-D) echocardiography in the evaluation of cardiac anatomy in patients with congenital heart disease, 2-D echocardiograms were performed in 126 infants and children before cardiac catheterization and angiocardiography. The segmental echocardiographic analysis included determination of intracardiac, great artery, systemic venous and pulmonary venous anatomy. The 126 patients had 259 separate cardiovascular abnormalities, of which 226 (87%) were prospectively identified by 2-D echocardiography. There were 8 false-positive diagnoses. The most common lesions and the sensitivity and specificity of echocardiography were: patent ductus arteriosus, 41 patients (83% and 100%, respectively), ventricular septal defect, 35 patients (86% and 100%); atrial septal defect, 26 patients (85% and 99%); pulmonary valve stenosis, 25 patients (77% and 97%), transposition of the great arteries, 16 patients (100% and 100%); and total anomalous pulmonary venous connection, 14 patients (85% and 100%). Less common defects and their rate of detection included coarctation of the aorta, 10 of 12 patients; atrioventricular canal, 10 of 10 patients; tetralogy of Fallot, 10 of 10 patients; aortic valve stenosis 8 of 8 patients; right aortic arch, 8 of 8 patients; interrupted aortic arch, 4 of 4 patients; and unilateral pulmonary vein atresia, 0 of 1 patient. In 33 patients (26%), the errors in echocardiographic analysis were judged to have surgical importance. Most errors were the result of overlooking or misinterpreting data that had been appropriately recorded on videotape. Pulmonary valve stenosis and patent ductus arteriosus are the lesions most likely to be misdiagnosed by ultrasound studies relying on imaging alone.  相似文献

Percutaneous treatment of multiple heart defects   总被引:1,自引:0,他引:1  
We describe our experience in 6 cases with multiple congenital heart defects treated by percutaneous intervention. Their age ranged from 2.3 to 10 years (mean 6.1), with follow-up from 1 to 84 months (mean 28.8). Two cases had coarctation of the aorta (AC) and persistent ductus arteriosus (PDA). Two patients had pulmonary valve stenosis (PVS) and PDA, one case with aortic stenosis (AE) and PDA and one case with AC, mitral stenosis and subaortic stenosis (Shone's Syndrome). Ductus arteriosus was occluded in all patients with Gianturco coils or Rashkind occluder. The valvular gradient post balloon decreased in cases with AC from 46 to 9 mmHg, with PVS from 110 to 10 mmHg and with AE from 40 to 14 mmHg. In a 8 year old boy with Shone's syndrome, we performed angioplasty of aortic coarctation, mitral valvuloplasty with Inoue catheter. He was referred to surgery for subaortic repair stenosis. All are asymptomatic at follow-up. In conclusion; percutaneous intervention is possible in patients with multiple congenital heart defects.  相似文献
