[A case of coronary artery embolism associated with combined valvular heart disease].
A 53-year-old-man afflicted with combined valvular heart disease and atrial fibrillation was admitted to our department complaining of chest pain. ST elevation on ECG (II, III, aVF) and elevated CPK value were recognized. He was diagnosed as having acute myocardial infarction, and percutaneous transluminal coronary recanalization was performed immediately. The coronary angiogram showed occlusions at the proximal left branch (#12). But these lesions could not be recanalized by 960000 IU urokinase administration. The cineangiogram after one month revealed perfect recanalization of these occlusions. Mitral stenosis with neovascularity to the left atrium and aortic regurgitation were recognized. We supposed this infarction caused by coronary embolism originated from left atrial thrombi. Acute myocardial infarction associated with mitral stenosis has been reported in fifteen cases previously in Japan, but only three cases revealed coronary occlusion in the acute phase with normal coronary artery in the chronic stage. However, there has been no report, except for this case, demonstrating occlusion in two coronary arteries at the same time. So, our case is the first report of the involvement of two coronary artery occlusions.
