Surgical treatment of infective endocarditis complicated by intracranial hemorrhage in a patient with hypertrophic obstructive cardiomyopathy.
A patient with hypertrophic obstructive cardiomyopathy developed mitral regurgitation due to infective endocarditis. The patient, a 29-year-old man with a 16-year history of a severe obstructive form of hypertrophic obstructive cardiomyopathy (left ventricular outflow gradient more than 100 mmHg), was admitted with bacteremia. During medical therapy with antibiotics for six months, the patient suffered an intracranial hemorrhage without a mycotic aneurysm and developed severe mitral regurgitation due to the infective endocarditis. One month after clinical stability of the cerebral damage, the patient underwent a combined mitral valve replacement and transaortic septal myectomy. Postoperative echocardiography revealed that the left ventricular outflow gradient had decreased to 15 mmHg. Ten months after the combined operation, the patient was well and asymptomatic.
