Echocardiographic diagnosis of anomalous origin of the left coronary artery from the pulmonary artery.

The aim of this research is to investigate the application value of TTE in the diagnosis of the anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA).The echocardiographic findings of 11 patients with ALCAPA confirmed by surgery in our hospital from October 2007 to December 2018 were retrospectively analyzed and compared with the preoperative computed tomography angiography (CTA) diagnosis and intraoperative diagnosis.Surgery was performed in all of the patients to establish the dual coronary artery system. Four underwent the Takeuchi procedure and 7 had re-implantation of the anomalous left coronary artery. The CTA diagnoses of the 11 patients were consistent with the surgical diagnoses, and the diagnostic accuracy was 100% (11/11). Echocardiographic diagnosis showed consistent results in 10 cases, while one case was misdiagnosed as endocardial fibroelastosis; the diagnostic accuracy was 90.9% (10/11). The echocardiographic features of these patients with ALCAPA included: abnormal left coronary ostium arising from the pulmonary trunk with retrograde coronary artery flow in 10 patients; enlargement of the right coronary artery in 8 patients; abundant intercoronary septal collaterals in 6 patients; and moderate and significant mitral regurgitation in 7 patients. Echocardiography showed that the left ventricular end-diastolic diameter and left ventricular end-systolic diameter before surgery were significantly different from those after surgery (P < .05) and that the left ventricular ejection fraction and fractional shortening before surgery were not significantly different from those after surgery (P > .05).Transthoracic echocardiography can diagnose ALCAPA in a timely, accurate, and noninvasive manner, and it could be of great significance in guiding clinical operations and in predicting prognosis.

Transthoracic echocardiographic diagnosis of anomalous origin of left coronary artery from pulmonary artery in children

Objective To analyze transthoracic echocardiographic characteristics of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) and to explore the diagnostic value of transthoracic echocardiography. Methods The transthoracic eehocardiographic characteristics of twenty-three children hospitalized with ALCAPA from 1996 to 2008 were analyzed retrospectively. The origin sites, blood flow directions of coronary arteries, accompanied cardiovascular abnormalities and valvular regurgitations were investigated. Fourteen cases performed angiographies and 21 cases underwent cardiac surgery. Results Echocardiography showed abnormal vessel inserting into pulmonary artery, continuous shunt into pulmonary artery, left ventricle dilatation and intercoronary collateral signals in all cases. Echocardiography revealed the main left coronary artery originating from pulmonary artery in 22 cases and left circumflex coronary artery from pulmonary artery in one. The diagnosis of ALCAPA was confirmed by angiocardiography or intraoperative findings in 22 patients and confirmed by cardiac spiral CT in one case. Conclusions Echocardiography cart reveal the left coronary artery originating from pulmonary artery, but it is still important to differentiate this abnormality from cardiomyopathy and endocardial fibroelastosis. Some pediatric patients have overlapped characteristics of both infant and adult type. Key words: Echocardiograohy; Coronary vessel anomalies

Echocardiographic Diagnosis of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery

The objective of this study was to analyze echocardiographic characteristics of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) and to explore the diagnostic value of transthoracic echocardiography. The echocardiographic characteristics of 8 patients hospitalized with ALCAPA from 2000 to 2005 were analyzed retrospectively, including the results of real time three-dimensional echocardiography in one case, and compared with angiographic results. Eight cases included 6 older type patients and 2 infant type patients. Echocardiography showed abnormal vessel inserting into pulmonary artery (PA), continuous shunt into PA and intercoronary collateral signals within the ventricular septum in all cases and bifurcate structure of the abnormal vessel with retrograde filling in 4 cases. The morphological and functional changes and valvular regurgitation induced by insufficient myocardial perfusion were also evaluated. In former 4 patients, 2 cases were misdiagnosed as right coronary artery-PA fistula and the other 2 cases were given an uncertain diagnosis of anomalous origin of the coronary artery because of the visualization of the echo-free linear structure which apparently arose from the aorta resembling a normal left coronary artery. The latter 4 patients were correctly diagnosed by excluding the aforementioned interference. The diagnosis of ALCAPA was confirmed by angiocardiography in all patients and by intraoperative findings in 4 patients. Based on the apprehension of ultrasonic features and the enhancement of diagnostic alertness, the echocardiography can evaluate ALCAPA accurately and give more information than angiography. It may be the first diagnostic choice.

Echocardiographic diagnosis of anomalous origin of the left coronary artery from the pulmonary artery

We found increased systolic coronary flow in transthoracic pulsed wave (PW) Doppler in a 42-year-old patient with anomalous origin of left main coronary artery from the pulmonary artery. This is a characteristic echocardiographic finding in this anomaly in the presence of collateral circulation and coronary L-R shunt. In comparison with so far used echocardiographic criteria this parameter when present allows quick recognition of anomalous origin of left coronary artery from the pulmonary artery, and its differentiation from other potentially lethal coronary anomalies.

Cross-sectional and Doppler echocardiographic diagnosis of anomalous origin of the left coronary artery from the pulmonary artery and right coronary artery from posterior aortic sinus

A six-year-old asymptomatic child on evaluation for a cardiac murmur, was found on cross-sectional and Doppler echocardiography to have an anomalous origin of the left coronary artery from the pulmonary artery and right coronary artery from posterior sinus of aorta. Doppler studies revealed a continuous signal in the pulmonary artery, indicating a left to right flow. The diagnosis was subsequently confirmed at cardiac catheterization and surgery.

Misleading echocardiographic diagnosis of anomalous origin of the right coronary artery from the pulmonary artery

AbstractWe report on a case of a newborn with echocardiographic diagnosis of anomalous origin of the right coronary artery from the main pulmonary artery. Intraoperative inspection demonstrated a proximal anomalous course of the right coronary artery but a normal origin from the right sinus of Vansalva of the Aorta. We suggest a complete investigation, including coronary angiography, when isolated and rare congenitaj malformations of the coronary arteries are suspected.

Two-dimensional echocardiographic diagnosis of anomalous origin of the right pulmonary artery from the aorta: Differentiation from aortopulmonary window

Utilizing two-dimensional echocardiography, the diagnosis of anomalous origin of the right pulmonary artery from the aorta was made prospectively in a neonate who presented with signs of congestive heart failure. A complete echocardiographic evaluation, including both right parasternal short-axis and suprasternal long-axis scans, permitted differentiation from other defects in aortopulmonary septation.
