Coronary embolism and subsequent myocardial abscess complicating ventricular aneurysm and tachycardia.
A 62-year-old female experienced a ventricular aneurysm and tachycardia caused by coronary embolism from mitral valve endocarditis. The patient underwent endoventricular patch plasty and cryoablation concomitant with valve replacement and survived without any operative complications. Pathological examination suggested that abscess formation played an important role regarding the disruption of the ventricular wall and development of the ventricular aneurysm and tachycardia. In previous reports, a myocardial abscess caused by a septic embolism has only been diagnosed using postmortem examinations as colony growth around the capillary vessels in the myocardium. We considered that our operation was effective and feasible in such an occurrence.
