“…With the development of ultrasonic imaging, transthoracic echocardiography (TTE) serves as a noninvasive method for diagnosis of ALCAPA by providing important information including the anatomic, functional, and hemodynamic evaluation of the cardiovascular system. 16 , 17 Although significant progress has been made in echocardiographic imaging of cardiovascular disease over the last decade, its diagnostic value in ALCAPA is not well understood. In this article, we present our experience of analyzing echocardiographic findings in a group of patients diagnosed with ALCAPA.…”

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary abnormality associated with early infant mortality and sudden death in adults. Transthoracic echocardiography (TTE) plays an important role in early detection and diagnosis of ALCAPA as a noninvasive modality. However, its diagnostic value is not well studied. The purpose of this study is to determine the performance of TTE in the diagnostic assessment of ALCAPA as compared with coronary CT and invasive coronary angiography.A total of 22 patients (13 women and 9 men, mean age, 12.9 ± 19.5 years) with ALCAPA who underwent echocardiographic examination for clinical diagnosis were retrospectively reviewed and analyzed. Transthoracic echocardiographic features of ALCAPA were analyzed and its diagnostic value was compared with invasive coronary angiography and coronary CT angiography (CTA) with surgical findings serving as the gold standard. Surgery was performed in all of the patients to establish the dual coronary artery system. Five underwent the Takeuchi procedure and 17 had re-implantation of the anomalous left coronary artery. Of 20 patients, echocardiographic diagnoses were in good agreement with findings at surgery, resulting in the diagnostic accuracy of 90.9%. Two cases were misdiagnosed—one as the right coronary artery to pulmonary artery fistula and the other as rheumatic heart disease. The echocardiographic features of these patients with ALCAPA included: abnormal left coronary ostium arising from the pulmonary trunk with retrograde coronary artery flow in 20 patients; enlargement of the right coronary artery in 17 patients; abundant intercoronary septal collaterals in 17 patients; and moderate and significant mitral regurgitation in 14 patients. The diagnostic accuracy of invasive coronary angiography (in 17 patients) and coronary CTA (in 9 patients) was 100%.This study shows that TTE is an accurate, noninvasive imaging modality for displaying the origin of coronary arteries and demonstrating the coronary courses as well as other associated abnormalities in patients with ALCAPA.

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.

Background: Myocardial perfusion imaging by single photon emission computed tomography (MPI–SPECT) is noninvasive test that can give an important information for the diagnosis of coronary artery disease (CAD), detect reversible ischemia, quantify defect sizes and help in clinical decisions of interventions as well as assessment of disease prognosis. Tissue Doppler imaging (TDI) emerged as a potential modality for assessing systolic and diastolic LV performance. Strain doppler echocardiography (SDE) is a new tool for measuring regional myocardial deformation excluding the effect of adjacent myocardial tissue. The development of Instantaneous wave-free Ratio (IFR) as a relatively new invasive method for physiological assessment of coronary lesions without the use of pharmacologic hyperemic agents is the golden standard test for assessment of intermediate coronary lesions and guiding the revascularization decision. Methods: This Cross-sectional study was done was conducted on 50 cases with intermediate coronary artery lesions admitted at the Cardiology departments in Benha University, Kobry Elkobba Military Hospital and Air Force Specialized Hospital. All groups were subjected to history and clinical examination, cardiac examination, 12 lead ECG, 2D echocardiography, routine laboratory investigations, coronary angiography with evaluation of intermediate lesion by IFR then TDI and SDE for evaluation the regional myocardial deformation of the segments supplied by the same coronary artery, after that 99mTc-sestamibi (MIBI) SPECT imaging was done to quantify defect size and finally correlation was done between results of IFR, TDI and SPECT to guide the revascularization decision. Results: Pearson’s correlation analysis showed that; Gated single-photon emission computed moderate and severe Ischemia, Sm-velocity, WMSI, DT, had a highly significant positive correlation with IFR value (p < 0.001). E/A ratio, Mean E/e’ velocity ratio, FS, LVEF and LV GLS had a highly significant negative correlation with IFR value (p < 0.001). Conclusions: Instantaneous wave-free Ratio (IFR) modality is a reliable measure to guide functional significance of the intermediate coronary artery lesions for decision making and guiding plan of management. But it is an expensive and invasive modality. On the other hand, SPECT and tissue doppler modalities showed high sensitivity and specificity in the same group of patients with less expensive, non-invasive and no contrast use advantages.
