[Three cases of coronary to pulmonary arterial fistulae combined with valvular disease].

Three cases of coronary to pulmonary arterial fistulae (CAF) combined with valvular disease are reported. The first case was 53-year-old male admitted with mitral stenosis (MS) and left atrium thrombus. CAF originating from both coronary artery and draining to pulmonary artery were found by coronary angiography. Open mitral comissurotomy (OMC), thrombectory and ligation of CAF were performed. Case 2 was 52-year-old female suffered from CHF due to MS. Abnormal communication from left coronary artery to pulmonary artery was demonstrated. OMC and ligation of CAF were performed. Case 3 was 65-year-old male with combined valvular disease. MS, aortic regurgitation and CAF from right coronary artery to pulmonary artery were revealed. Mitral and aortic valve replacement and ligation of CAF were done. Diffusion of coronary angiography increase chance to reveal coronary artery fistulas during examination of acquired cardiac disease. Coronary artery fistulas draining into pulmonary artery were completely ligated by double ligation at both the arising point from coronary artery and the draining point to pulmonary trunk.
