Summary Considerable controversy surrounds the optimal management of symptomatic infants with anomalous origin of the left coronary artery from the pulmonary artery; this includes the timing and type of surgical intervention. Long-term follow-up was obtained on three patients who had simple ligation of the anomalous left coronary artery at or before 8 months of age; long-term follow-up on an adolescent treated with a saphenous vein bypass graft from the aorta to the coronary artery was available for comparison. Remarkable increase in left ventricular contractility was observed in the three patients treated only by simple ligation of the anomalous left coronary artery during infancy. Thallous chloride T1 201 exercise studies disclosed no perfusion abnormalities in any of the patients despite angiographically demonstrable wall-motion abnormalities in two of the four patients. Our study suggests that simple ligation of the anomalous left coronary artery near its origin in patients with angiographically detectable left-to-right shunting can provide long-term survival with good left ventricular function and minimal clinical complaints. 相似文献

A rare and striking echocardiographic finding with color-flow Doppler—visualization of intercoronary collaterals within the
ventricular septum—in an asymptomatic 5-year-old girl is reported. It strongly suggests anomalous origin of the left coronary
artery from the pulmonary artery. Several additional echocardiographic features can secure the diagnosis and allow one to
proceed with surgical correction without confirmatory cardiac catheterization and angiocardiography. The ages of our patient
and of the seven cases reported previously suggest that these collaterals will more likely be identified beyond infancy and
in relatively asymptomatic patients with this congenital anomaly. 相似文献

Anomalous origin the left coronary artery from the pulmonary artery (ALCAPA) is an extremely rare congenital coronary abnormality that may be difficult to diagnose by echocardiography. Most patients present with a potentially fatal illness leading to sudden cardiac death during infancy. This report describes a 15-year-old girl who had 15-year history of cardiac murmur but with no clinical symptoms. Echocardiographic examination was normal, but a 320-slice computed tomographic (CT) scan showed the anomalous origin of the left coronary artery form the pulmonary artery. This case demonstrates that the 320-slice CT scan is a sensitive and reliable technique for establishing the diagnosis of ALCAPA in both symptomatic and asymptomatic patients when it cannot be visualized by echocardiography. 相似文献

A 38-year-old woman was discovered to have a systolic murmur for an unrelated complaint. Transesophageal echocardiography
showed no atrial or ventricular septal defects, but multiple large collateral vessels in inter-ventricular septum. The origin
of left coronary artery was not seen at the expected site on the aortic root. The 64-multislice computed tomography confirmed
the diagnosis of an anomalous origin of the left coronary artery from the pulmonary artery. Left coronary artery was revascularized
with a saphenous vein graft with an uneventful recovery. 相似文献

The landmark 1933 case report from Massachusetts General Hospital by Bland, White and Garland (Am Heart J 8:787–801) described
a 3-month-old child with progressive feeding problems, cardiomegaly on chest radiography, and EKG evidence of left ventricular
damage. Of interest was the fact that the vigilant father of the infant was Aubrey Hampton, a radiologist and future chairman
of radiology at Massachusetts General Hospital. At autopsy, the left coronary artery originated from the pulmonary artery
rather than from the aorta. Effective treatment for this condition was not available until 1960 when Sabiston, Neill and Taussig
showed that the blood flowed from the left coronary artery toward the pulmonary artery. The anomalous left coronary artery
was ligated at its junction with the pulmonary artery and the child survived. This historical review of Bland-White-Garland
syndrome, now known as anomalous left coronary artery arising from the pulmonary artery (ALCAPA), stresses the continued diagnostic
significance of cardiomegaly on chest radiography and EKG changes suggesting left ventricular damage in 2- to 3-month-old
infants with feeding intolerance or irritability. With a high index of suspicion, an echocardiogram can be obtained to confirm
the diagnosis. Modern surgical methods involve left coronary artery translocation and afford excellent outcomes. 相似文献

Summary In five infants, anomalous left coronary from the pulmonary artery (ALCA) was diagnosed by selective pulmonary artery angiography
using the “stop flow” technique: the left pulmonary artery was occluded by inflating a balloon and a large bolus of dye was
injected proximal to the balloon at a high flow velocity. These conditions, by increasing pulmonary artery pressure, increase
the chances of imaging directly an ALCA. It also leaves the left pulmonary artery branches free of contrast medium and allows
easier visualization of ALCA, mainly in the antero-posterior view. When an ALCA is injected from the pulmonary artery, left
heart catheterization can be avoided. However, a false-negative result is to be expected in specific conditions and was observed
in one of our patients. If pulmonary angiography fails to prove a ALCA, left heart catheterization remains mandatory to exclude
the diagnosis. 相似文献

Anomalous origin of the left coronary artery from the pulmonary artery (ALCA-PA) is a rare form of congenital heart disease. In this report, three cases with this anomaly are described; two patients presented in infancy with heart failure from myocardial ischemia and infarction, while the third was asymptomatic and ALCA-PA was diagnosed during evaluation of a residual murmur after surgery for associated cardiac defects (ventricular septal defect and patent arterial duct). All three cases underwent aorto-pulmonary tunnel repair (Tukeuchi procedure), and to our knowledge two of them are the first infantile cases reported in Turkey. 相似文献

This study aimed to illustrate the experience of treating children with anomalous origin of the left coronary artery from
the pulmonary artery (ALCAPA). The clinical data for 19 children with ALCAPA admitted to Beijing Anzhen Hospital from August
1993 to June 2009 were reviewed. According to the data, 47.4% (9/19) of the patients had a misdiagnosis of endocardial fibroelastosis,
and 15.8% (3/19) had a misdisgnosis of dilated cardiomyopathy. Electrocardiography showed abnormal Q waves with T wave inversion
in leads I, avL, and V4-V6 of 18 patients, especially in lead avL. The ratio of proximal right coronary artery diameter to
aotic root diameter exceeded 0.20 for 15 of 16 patients. Apical ventricular aneurysm or aneurysmal dilation (52.6%,10/19),
enhanced echogenicity of papillary muscles (84.2%, 16/19), and increased coronary collaterals (78.9%, 15/19) were detected
frequently during echocardiography. A total of 18 patients underwent cardiac surgery including left coronary artery (LCA)
ligation for 1 patient (5.6%), LCA ligation plus coronary artery bypass grafting for 1 patient (5.6%), Takeuchi operation
for 7 patients (38.9%), and LCA reimplantation for 9 patients (50.0%). Five patients died in the hospital, and the remainder
were asymptomatic during a follow-up period of 6 to 166 months. Their abnormal Q waves gradually regressed, and left ventricular
systolic function and size returned to normal with alleviation of mitral insufficiency. The clinical features of ALCAPA are
helpful for determining an accurate diagnosis. This anomaly can be treated successfully by several types of operations with
good prognosis. 相似文献

Coronary arteriovenous fistulas are rare anomalies resulting in abnormal communication between the coronary artery and any chamber of the heart. An asymptomatic patient was referred for evaluation of her murmur. Two-dimensional and color Doppler echocardiographic evaluation revealed an enlarged left main coronary artery. A retrograde, eccentric small jet was found within the right ventricular outflow tract at the pulmonary artery valvular level allowing us to detect the entrance site of the fistula. The diagnosis was confirmed by cardiac catheterization and angiocardiography. Although our case was asymptomatic, the decision to perform cardiac surgery was made because of the aneurysmatic appearance of the left coronary artery. In our opinion, visualization of coronary arteries by two-dimensional echocardiography, together with additional information obtained from the Doppler examination, provides an excellent technique for the noninvasive diagnosis of coronary artery fistula. 相似文献

OBJECTIVE: To describe the 5-year cumulative incidence of cardiac dysfunction in human immunodeficiency virus (HIV)-infected children.Study design: We used a prospective cohort design, enrolling children at 10 hospitals. Group I included 205 vertically HIV-infected children enrolled at a median age of 1.9 years. Group II consisted of 600 HIV-exposed children enrolled prenatally or as neonates, of whom 93 were ultimately HIV-infected. The main outcome measures were echocardiographic indexes of left ventricular dysfunction. RESULTS: In group I, the 5-year cumulative incidence of left ventricular fractional shortening =25% was 28.0%. The 5-year incidence of left ventricular end-diastolic dilatation was 21.7%, and heart failure and/or the use of cardiac medications 28.8%. The mortality rate 1 year after the diagnosis of heart failure was 52.5% [95% CI, 30.5-74.5]. Within group II, the 5-year cumulative incidence of decreased fractional shortening was 10.7% in the HIV-infected compared with 3.1% in the HIV-uninfected children (P =.01). Left ventricular dilation, heart failure, and/or the use of cardiac medications were more common in infected compared with uninfected children. CONCLUSIONS: During 5 years of follow-up, cardiac dysfunction occurred in 18% to 39% of HIV-infected children and was associated with an increased risk of death. We recommend that HIV-infected children undergo routine echocardiographic surveillance for cardiac abnormalities. 相似文献

Background. ALCAPA is the anomalous origin of the left coronary artery from the pulmonary artery. It leads to more or less severe myocardial ischemia.The patients may manifest as infants with severe cardiac failure and mitral regurgitation,others may reach adulthood without symptoms. Methods and patients. Five children were operated upon for this anomaly in this center during the past 2 years.At the same time 2 adults were detected. Results. The diagnosis was made in the neonatal period in one patient, the oldest patient was 58 years of age at the time of the diagnosis. The left coronary artery was reimplanted into the aorta in all children. 2 patients after extremly poor preoperative situations needed temporary extracorporeal assist devices. All patients showed improvement of myocardial function after surgery. Conclusion. Surgery for ALCAPA should be performed soon after diagnosis has been made.The postoperative course is influenced by the preoperative degree of myocardial lesion and mitral regurgitation.Even desperate cases can be treated successfully and with good long term results by efficient intensive care using ventricular assist devices or ECMO. 相似文献

The anomalous origin of the left coronary artery from the pulmonary artery (Bland-White-Garland Syndrome) is a rare congenital malformation reported to occur in 0.25-0.5% of all congenital cardiac anomalies. The clinical and pathomorphological picture can be classified into 2 types: infantile or adult. The infantile type is thought to lack coronary collaterals; this explains the bad prognosis and symptoms of non-operated patients. In the adult type collaterals are present or have developed in time to provide adequate blood supply to the myocardium. No history of cardiac complains and a nearly normal ECG are common findings. Echocardiography and cardiac catheterisation are mandatory diagnostic tools. The value of new methods like NMR, "stop-flow" angiography and color doppler flow mapping is still in discussion. The reimplantation of the coronary artery and Takeuchi-Operation are well established surgical methods. The time for the operation and prognostic outcome are related to the preoperative underlying myocardial damage measured by left ventricular function. 相似文献

Summary We report a case of tetralogy of Fallot with an unsuspected anomalous left anterior descending coronary artery arising from
the right coronary artery and crossing the right ventricular outflow tract in a 16-month-old infant. During operation, the
anomalous artery was severed. Successful repair of the intracardiac anomalies was performed, including left anterior descending-internal
mammary artery reconstruction of the anomalous artery. This case illustrates the importance of delineation of coronary artery
anatomy and even selective coronary arteriography in patients with tetralogy of Fallot, since anomalous coronary arteries
occur most frequently in association with other cardiac anomalies. Arteriography 10 years later revealed a patent anastomosis
to the left anterior descending artery, proving the durability of the internal mammary artery in a patient we believe to be
the youngest to have undergone bypass with this particular conduit. 相似文献
