Current characteristics of congenital coronary artery fistulas in adults: A decade of global experience

Table 2 Comparison between unilateral, bilateral and multilateral fistulas related to site of origin, aneurysmal formation, mode of termination and management

	Unilateral (n = 243) (80%)	Bilateral (n = 55) (18%)	Multilateral (n = 6) (2%)
Termination
PA1	44%	73%	75%
CS/RA	28%	18%	10%
LA	2%	5%	--
LV	6%	4%	15%
RV	13%	4%	--
Aneurysm	13%	16%	33%
Management
SL	57%	51%	66%
CMM	20%	32%	17%
PTE	23%	17%	17%

¹Statistical significance was reached between termination into pulmonary artery (PA) (29%) vs exit to all other sites (10.6%) (P = 0.000). CS/RA: Coronary sinus/right atrium; LA: Left atrium; LV: Left ventricle; RV: Right ventricle; SL: Surgical ligation; CMM: Conservative medical management; PTE: Percutaneous therapeutic embolization.
