Left circumflex artery fistula to left atrium: a rare case report

Abstract

Coronary artery fistulas are rare congenital anomalies of coronary termination. There are 3 types: (1) cameral coronary fistulas, (2) pulmonary coronary fistulas, and (3) bronchial coronary fistulas. Left circumflex coronary artery to left atrial fistula are exceptional. Imaging, especially the CT angiogram, must establish an anatomical classification of the fistula for therapeutic purposes, by specifying its origin, its path, its size and its termination. We report a rare case of the left circumflex coronary artery to left atrial fistula in a 31 year old man, which is an uncommon presentation of coronary termination anomalies. The CT coronary angiogram must describe the origin segment of the fistula and the drainage site which have therapeutic consequences.

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 ].…”

“…CCTA has gained a major role in coronary anomalies assessment, thank high spatial and temporal resolution, and lower radiation exposure. The possibility of different types of post-processing approaches, including multiplanar and three-dimensional reconstructions, allows a precise visualization of the anatomical configuration of the coronary tree that can be difficult to identify on 2D fluoroscopic images [3] , [4] , [5] , [6] .…”
