Color Doppler and pulse wave assessment of flow in anomalous origin of left coronary artery from pulmonary artery: Pre- and post-surgery.

ABSTRACT: Changes in left coronary artery flow pattern in anomalous left coronary from pulmonary artery can provide valuable insight into pathology and natural history of disease. We wish to discuss a case with pre and post operative left coronary flow pattern with mid term follow up.

Project description:ObjectiveThe purpose of this study was to evaluate the prognosis of patients with anomalous left coronary artery originating from pulmonary artery with varying cardiac function after surgical correction.MethodsThis was a single-center retrospective cohort study including 51 patients with anomalous left coronary artery originating from pulmonary artery, all of whom underwent surgery at our center.ResultsAll 5 deaths occurred in the pre-operative low cardiac function group (n = 39). After corrected by body surface area, parameters such as left coronary artery, right coronary artery, left atrial diameter, left ventricular end-diastolic diameter, left ventricular end-systolic diameter, and main pulmonary artery diameter, were lower in patients in the normal cardiac function group than in the low cardiac function group. The rate of collateral circulation formation was higher in the normal cardiac function group. The proportion of changes of T wave was higher in the low cardiac function group (P = 0.005), and the duration of vasoactive drugs (dopamine, milrinone, epinephrine, nitroglycerin.) was longer in the low cardiac function group. Left ventricular end-diastolic diameter, left ventricular end-systolic diameter, main pulmonary artery diameter, and left atrial diameter were smaller than those pre-operatively (P < 0.05). Left ventricular ejection fraction was higher than that pre-operatively (P = 0.003). The degree of mitral regurgitation in the low cardiac function group was reduced post-operatively (P < 0.001).ConclusionThere was a significant difference between the pre-operative baseline data of the low cardiac function group and the normal cardiac function group. After surgical repair, cardiac function gradually returned to normal in the low cardiac function group. The low cardiac function group required vasoactive drugs for a longer period of time. The left ventricular end-diastolic diameter, left ventricular end-systolic diameter, left atrial diameter, and main pulmonary artery diameter decreased and gradually returned to normal after surgery. The degree of mitral regurgitation in the low cardiac function group was reduced after surgery.
