Abstract:
Objective The purpose of this study was to analyze the anatomy variation of coronary vein system in patients with ischemic heart disease (IHD) and non-ischemic heart disease (NIHD).Method Forty-one patients with IHD and 87 patients with NIHD [101 men, mean age (63.5 ± 10. 6)years] were included in this study. Results Coronary sinuses were successfully cannulated and venographies were obtained in 127 cases. Transvenous LV pacing leads were successfully placed in optimal coronary vein in 123 cases (96. 09% ). The majority (76. 38% ) patients had at least one or more vessel abnormalities (thinness, stenosis, tortuousity, lack of lateral marginal vein or postero-lateral vein). The incidence of thin and tortuousity was significantly higher in lateral marginal vein than that in postero-lateral vein (P <0. 05 -0. 01 ). The incidence of lack of postern-lateral marginal vein was more frequent than the lack of lateral vein (P < 0. 05 ). The rate of abnormality in both vessels was 25. 2%. Incidence of vein lack in male was more frequent than in female ( P < 0. 05 ). The thin and tortuousity of vessels in female were more frequent than in male ( P < 0. 05 ) . The incidence of thin and tortuousity of postero-lateral and abnormality of both vessels was significantly higher in IHD than in NIHD patients ( P < 0. 05 ). All coronary sinus myocardial bridges occurred in NIHD. Stenoses of left anterior descending (LAD) and left circumflex (LCX) were mostly associated with abnormality of lateral vessels. Conclusions The anatomic variations of lateral and postern-lateral coronary vein were more frequent in this patient cohort. Vein lack in male was more frequent and the thin and tortuousity of vessels were less in male than in female patients. The ratio of vessel abnormality is higher in patients with IHD. Coronary arteries stenosis and position of infarction are associated with anatomic variations of coronary vein system.
