“…Furthermore, the post-processing of coronary CTA images is quite complex and rather time consuming. 11 – 15 In contrast, TTE is noninvasive, inexpensive, and safe and may be repeated as frequently as necessary. TTE findings of ALCAPA include visualization of the origin of the LCA from the pulmonary artery, proximal dilated and tortuous RCA, and visualization of abundant coronary collaterals especially, intercoronary septal collaterals.…”

“… 7 – 10 Despite its superior spatial resolution of visualizing the origin and course of left coronary artery (LCA), the main disadvantages of coronary CTA are relatively high radiation dose, contrast-induced acute kidney injury (CI-AKI) (the third most common cause of acute renal failure among hospitalized patients), high price, and its inability to assess cardiac function such as blood flow. 11 – 15 …”

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.

“…Although the coronary angiography and CTA are easier to visualize the origin and course of LCA, their main disadvantages are invasive, expensive, relatively high radiation dose, and inability to assess flow in CTA [1,[7][8][9][10][11][12][13]. Experience with accurate diagnosis of ALCAPA by echocardiography has accumulated [15,17,18].…”

“…However, misdiagnosis and missed diagnosis are still commonly reported. Although coronary computed tomography angiography (CTA), magnetic resonance imaging (MRI), and invasive angiocardiography were used for diagnosis of ALCAPA [1,[7][8][9][10][11][12][13], echocardiography is a harmless, cheap, and the most frequently used method to date. In echocardiography, the normal origin of LCA is clearly visualized at aortic short-axis view.…”
