[A case of bilateral coronary artery--pulmonary artery fistulas associated with mitral valve stenosis].
A case was reported of bilateral coronary artery-pulmonary artery fistulas associated with mitral valve stenosis. A thirty seven year old female was admitted with the complaint of exertional dyspnea and palpitation, which had lasted for the 3 years previous to her admission to our hospital. Electrocardiogram showed sinus bradycardia and no ST-T changes, but exercise ECG showed significant ST depression after 6 min of exercise. The DDR (9 mm/sec) and mitral valve area (0.61 cm2) were shown by UCG examination to have decreased, and the pressure at half time (360 msec) was shown by Doppler UCG to be prolonged. On cardiac catheterization, coronary arteriography showed fistula from RCA to PA, and fistula from LCA to PA, but no occlusive lesions were demonstrated. P/S blood flow ratio was 1.09, and O2 saturation was stepped up 3% in PA. She was operated on and given open mitral commissurotomy and closure of the fistula opening, via the PA. After surgical repair, no abnormality was found by exercise ECG, and no fistulas were shown on coronary arteriography.
