[III-P34-08] Anatomy of Coronary Artery Fistulas: A Review from Cases
Keywords:Anatomy, Coronary artery fistula, device closure
Introduction:The aim of our study was to assess the anatomy of the coronary artery fistulas(CAF).Materials and methods:A total of 7 patients (3 male, 4 female, mean age 22.3±21.4, range 1-62 year-old), who underwent CAG from 2013 to 2016 were reviewed for anatomy of CAF. All images were analysed and classified according to coronary anomalies. Variants considered were: the coronary dominance (right, left), characters of origin, course and termination of fistulas. Results:Segment 4 PD arises from LCA 1case(14%), from RCA 6cases(86%).Origin of Fistulas: LMT 2cases(29%), LAD 1case(14%), LCX 1case(14%), RCA 2cases(29%), 1case(14%) from both LAD and RCA. Termination of Fistulas: RA 2cases (29%), MPA 2cases (29%), CS 1case(14%), LA 1case(14%), LV 1case (14%). Course of Fistulas: LMT to RA 1case; LMT to LA 1case; RCA to RA 1case; RCA to CS 1case; LAD to MPA 1case; LCX to LV 1case; from both LAD and RCX to MPA 1case.Aneurysm 4cases(57%), non-Aneurysm 3cases(43%). According to Sakakibara classification: Type A-proximal type: 3cases(43%), Type B-distal type: 4cases(57%)Discussion: Fistular drainage to the right side is more than to the left side (5/2). Type A-proximal type is an advantage for transcatheter closure of fistulas by using device. Because enough space for device and not interfere with native branch. Conclusion: Transcatheter closure of CAF can be performed, fistular anatomy know well is recommended to prevent complications.
