Dual left anterior descending artery with anomalous origin of long LAD from pulmonary artery - rare coronary anomaly detected on computed tomography coronary angiography

Abstract

Dual left anterior descending artery is a rare coronary artery anomaly showing two left anterior descending arteries. Short anterior descending artery usually arises from the left coronary artery, while long anterior descending artery has anomalous origin and course. Dual left anterior descending artery with origin of long anterior descending artery from the pulmonary artery (ALCAPA) is a very rare coronary artery anomaly which has not been reported previously in the literature. We present the computed tomography coronary angiographic findings of this rare case in a young female patient who presented with atypical chest pain.

A New Variant of Dual Left Anterior Descending Artery Anomaly: Type XI

“…The long LAD artery takes a more variable course around the short segment, returning to the interventricular groove distally. 2,6,8,9 In previously described cases of dual LAD artery anomalies, the short LAD artery originates from either the main stem of the LAD artery or the left main coronary artery. [1][2][3][4][5][6][7][8][9][10] However, the current case was unique in that the short LAD originated from the right coronary sinus and then coursed within the proximal septum before emerging in the proximal interventricular groove.…”

The long LAD artery originated from the right coronary sinus and then coursed anterior to the main pulmonary artery before entering the distal interventricular groove.…”

Dual left anterior descending artery: Case series based on novel classification and its therapeutic implications

“…Four more articles that described the association of dual LAD with corrected transposition of great arteries [C-TGA] and anomalous origin of LAD from pulmonary artery [ALCAPA] were also excluded. 5 , 6 , 7 , 8 Two titles without abstracts were excluded. 11 publications such as a letter to the editor, review articles, duplicates were also omitted ( Fig.…”

A rare case of anomalous origin of the left anterior descending artery from the pulmonary artery

“…Surgical correction is very essential to minimize morbidity and mortality. Although ALCAPA has been well described in the literature, anomalous origin of isolated left anterior descending artery (LAD) from the pulmonary artery (PA) has been rarely reported . Here, we report a rare case of anomalous origin of the LAD from the PA.…”
