Congenital atresia of left main coronary artery

Abstract

Congenital atresia of the left main coronary artery is a very rare form of coronary anomalies with poor clinical outcomes if left untreated. Patients require surgical correction by coronary bypass grafting after diagnosis. Here we report a case of congenital left main atresia in a 36 years old woman who had previous heart surgery with this anomaly having gone undetected.

A rare case of congenital atresia of the left main coronary artery

“…CALM belongs to the broad spectrum of congenital abnormalities of the coronary arteries that are extremely variable and include anomalies of their origin, the course of the epicardiac coronary branches, and distal connections [ 6 , 8 ].…”

A rare case of Left Main Coronary Artery Atresia presenting as Dilated Cardiomyopathy and misdiagnosed as ALCAPA

“…According to some researchers, MDCT provides more precise details in a less invasive way than coronary angiography and is thus recommended for evaluation of congenital coronary abnormalities. [11] MDCT not only defines the anatomic course and the ostium shape, but also has less complications as coronary spasm than conventional coronary angiography. However, there is no reliable research reporting the use of MDCT in infants with coronary anomalies.…”

“…A LIMA graft for LMCAA appears to be a reasonable early interventional approach with successful results 1 year postoperatively. Nevertheless, due to the rarity of this disease, long-term postoperative outcomes have not been reported yet [2,4,5,8,9,11]. Alternative to bypass grafting, direct surgical reimplantation or reconstruction of the left main coronary artery using azygos vein have been described to provide the shortest and most efficient way for blood to the myocardium.…”

Rare Incidental Finding on Coronary Artery CT Angiography: Left Main Coronary Artery Atresia

“…2 The clinical CLMCAA spectrum ranges from asymptomatic cases (due to an efficient collateral system) to symptoms such as angina, tachyarrhythmias, syncope, and sudden death. 3,4 Surgical revascularization is recommended in symptomatic patients; however, preventive surgical treatment is controversial in asymptomatic patients without inducible myocardial ischemia. [1][2][3][4][5] Case report A 51-year-old man was referred for coronary artery computed tomography (CT) angiography to investigate atypical chest pain.…”
