Correction of anomalous origin of left coronary artery using left subclavian artery

A case of anomalous origin of the left coronary artery from the pulmonary artery is reported in which surgical correction by anastomosis of the left subclavian artery to the left coronary artery was performed at the age of 6 months. There was a dramatic clinical improvement, and at 22 months repeat angiocardiography disclosed a patent graft and remarkable improvement in left ventricular function. It is recommended that this is the operation of choice for infants in whom cardiac catheterisation fails to show a shunt into the pulmonary artery or the shunt is small.     

Percutaneous transluminal coronary angioplasty of anomalous left circumflex coronary artery

We present our experience of percutaneous transluminal coronary angioplasty in two patients with an anomalous left circumflex coronary artery with severe stenosis. In the first case, the anomalous vessel originated from the first portion of the right coronary artery, and in the second case it originated from the right sinus of Valsalva. Cannulating the anomalous vessel with the guiding catheter can be difficult. The right Judkins-type catheter, with a posteriorly directed tip, is the most appropriate catheter for cannulating the anomalous circumflex artery when the vessel originates from the first portion of the right coronary artery, and the left Amplatz-type 1 is most appropriate when the vessel originates from the right sinus of Valsalva.

Imaging characteristics of anomalous left coronary artery from the pulmonary artery

SUMMARY: The authors report the imaging characteristics of the anomalous origin of the left coronary artery from the pulmonary artery in a 6 1/2-month-old male infant using electrocardiography, echocardiography, angiography, and electron-beam computed tomography. The patient presented with tachycardia, prolonged and interrupted feeding, failure to thrive, and myocardial infarction, and after diagnosis of the anomalous origin of the left coronary artery, survived the reimplantation of the left coronary artery directly to the ascending aorta. When reviewed 7 months after surgery, echocardiography showed improved left ventricular function and surface electrocardiography showed regression of pathologic Q waves in leads I, V 4, V 5, and V 6.     

Successful percutaneous treatment of anomalous left coronary artery from pulmonary artery

Anomalous origin of the left main coronary artery from the pulmonary artery (ALCAPA) is an uncommon congenital condition seen in the adult population, with most patients developing symptoms in infancy. We describe successful closure of an ALCAPA in an adult using a percutaneous transcatheter approach in a patient with evidence of anterior wall ischemia believed to be the consequence of myocardial steal. A 30-year-old female was noted to have continuous flow in the right ventricular septum on transthoracic echocardiography, with subsequent imaging confirming the presence of an ALCAPA. Myocardial perfusion imaging confirmed anterior wall ischemia, and as a strategy to optimize coronary perfusion pressure, the patient underwent percutaneous ALCAPA closure using an Amplatzer vascular plug. The procedure was well tolerated, with no evidence of anterior ischemia or myocardial dysfunction. Follow up perfusion imaging demonstrated no residual anterior wall ischemia. Transcatheter closure of an ALCAPA is a potentially safe and effective alternative treatment strategy in this patient population.     

Repair of anomalous left coronary artery from the right pulmonary artery

Surgical correction of anomalous left coronary artery from the right pulmonary artery is achieved by either direct implantation of the left coronary artery into the aorta or creation of a conduit between the two. We modified a technique originally described by Tashiro for the main pulmonary artery, by using a circumferential section of right pulmonary artery wall to create a conduit with a side-to-side anastomosis onto the aorta.     

A rare case of anomalous left circumflex coronary artery from the left pulmonary artery

The anomalous origin of the coronary artery in children is a rare disease. In particular, an anomalous origin of the left coronary artery from the pulmonary artery is a fatal condition in neonate with myocardial failure. A 46-month-old child with an anomalous origin of the left circumflex artery from the left pulmonary artery was detected due to asymptomatic cardiac murmur and immediately re-implantation of the left circumflex coronary artery was carried out successfully.     

Stenting of an anomalous left circumflex coronary artery arising from the right coronary artery

Coronary angioplasty can provide excellent means of revascularization of anomalous coronary arteries. Successful application of angioplasty to these vessels requires angiographic knowledge of their course, structure and appropriate equipment selection. Advancement of stent delivery systems in such cases requires good support with the possibility of selective cannulation and deep engagement of the guiding catheter. We report a case of stent placement in an anomalous circumflex artery arising from the right coronary artery.     

Repair of anomalous origin of left coronary artery from the pulmonary artery

Patients with anomalous origin of the left coronary artery from the pulmonary artery often have mitral valve regurgitation. Although establishing dual coronary circulation is the procedure of choice, there remains controversy as to how the mitral valve is handled. Between April 1999 and August 2005, 8 patients underwent surgical correction at our institution. There were 4 males and 4 females, aged from 9 months to 13 years (mean, 6.4 years). Six patients underwent direct aortic reimplantation and 2 had a Takeuchi procedure. Simultaneous mitral annuloplasty was performed in 7 patients with moderate or severe mitral regurgitation. There were no deaths or postoperative complications. Follow-up ranged from 4 to 80 months (mean, 34 +/- 26 months). Left ventricular function improved significantly from a preoperative fractional shortening of 0.21 +/- 0.09 to 0.35 +/- 0.06. Mitral regurgitation decreased on follow-up in the 7 patients who had mitral annuloplasty. We recommend performing mitral annuloplasty at the time of operation in patients with moderate or severe mitral regurgitation and anomalous origin of the left coronary artery from the pulmonary artery.

Klinefelter's syndrome with anomalous origin of left main coronary artery

Klinefelter's syndrome is a rare entity. Even rarer is an anomalous origin of the Left Main Coronary Artery. For both conditions to occur in the same patient is hence exceedingly rare. Reported here is a never previously reported case of a coronary congenital anomaly in a patient with Klinefelter's syndrome together with the proper angiographic approach.     

Multivessel coronary angioplasty with anomalous origin of the left main coronary artery

We report a case of coronary angioplasty to the right coronary artery, the circumflex, and the left anterior descending artery in a patient with anomalous left main coronary artery arising from the right aortic sinus of Valsalva. At angiographically documented follow-up of more than 2 years, the patient remains well without restenosis. This case represents the only such report in the literature. Angioplasty hardware was an important factor in successful crossing and dilatation of multiple severe and distal stenoses in the anomalous left system; appropriate technical details are discussed.     

Imaging the elusive anomalous origin of left coronary artery from pulmonary artery

A 7‐year‐old girl with severe mitral regurgitation and pulmonary artery hypertension with good ventricular function was planned for mitral valve repair, but was subsequently diagnosed to have anomalous left coronary artery from pulmonary artery. We describe the pitfalls in the diagnosis of this rare anomaly, particularly in the presence of severe pulmonary artery hypertension and absence of circumstantial evidence of coronary steal and ventricular dysfunction.     

An operation for anomalous origin of left coronary artery.

Successful surgical correction for anomalous origin of the left coronary artery from the pulmonary artery in a 4-year-old child is reported. An aortopulmonary fistula was created and a pericardial baffle was inserted within the pulmonary artery to connect the fistula to the ostium of the left coronary artery. The clinical, haemodynamic, and angiographic features of the anomaly are presented. The child's progress is satisfactory 17 months after the operation.     

Anomalous origin of the left coronary artery from the pulmonary artery: natural history and normal pregnancies

Two female patients are described with anomalous origin of the left coronary artery arising from the pulmonary artery who sustained an anterolateral myocardial infarction in infancy. Neither patient received surgical treatment although both have lived to middle age with minimal cardiovascular problems and have had uncomplicated pregnancies. Good exercise tolerance and long term survival may be possible even without surgery for patients with this anomaly.
