Summary of "Echocardiographic Diagnosis of Anomalous Single Coronary Artery from the Pulmonary Artery: Use of Bubble Contrast Echocardiography."

Anomalous origin of a coronary artery from the pulmonary artery (PA) is a rare congenital anomaly with the most common pattern being an anomalous left coronary artery (LCA) from the pulmonary artery (ALCAPA). A very rare pattern is the anomalous origin of a single coronary artery from the pulmonary artery (ASCAPA) wherein the single coronary ostium supplies both the right and left coronary systems with profound myocardial ischemia developing once PA pressures begin to fall after birth. Previous reports of this anomaly have all been based on post-mortem findings or pre-mortem angiographic diagnosis [1-3]. Notably, these children often present in extremis due to cardiogenic shock. Institution of veno-arterial extracorporeal life support can be catastrophic as it would lead to myocardial ischemia due to PA decompression. We present here the first echocardiographic-only diagnosis of ASCAPA in a 2-month-old child with the use of bubble contrast echocardiography to help confirm the diagnosis. The patient was resuscitated from a cardiac arrest on arrival with subsequent echocardiographic-only diagnosis. Surgical repair was undertaken with administration of cardioplegia into the pulmonary root with snaring of the branch PAs, and re-implantation of the single coronary to the aorta. At 3-month follow-up, he is thriving clinically with echocardiogram showing improving-though still somewhat depressed-left ventricular function.

Medical and Biotech [MESH] Definitions

Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.

A congenital coronary vessel anomaly in which the left main CORONARY ARTERY originates from the PULMONARY ARTERY instead of from AORTA. The congenital heart defect typically results in coronary artery FISTULA; LEFT-SIDED HEART FAILURE and MITRAL VALVE INSUFFICIENCY during the first months of life.

Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.

Malformations of CORONARY VESSELS, either arteries or veins. Included are anomalous origins of coronary arteries; ARTERIOVENOUS FISTULA; CORONARY ANEURYSM; MYOCARDIAL BRIDGING; and others.

An anomalous pulmonary venous return in which the right PULMONARY VEIN is not connected to the LEFT ATRIUM but to the INFERIOR VENA CAVA. Scimitar syndrome is named for the crescent- or Turkish sword-like shadow in the chest radiography and is often associated with hypoplasia of the right lung and right pulmonary artery, and dextroposition of the heart.
