[A rare case report of incarceration of Lambl's excrescence of aortic valve resulting in myocardial infarction].

We report a rare autopsy case of Lambl's excrescence of the aortic valve resulting in myocardial infarction. A 50-year-old female patient was referred to our hospital, but she died 4 hours after admission due to myocardial infarction. Autopsy disclosed Lambl's excrescence of the aortic valve, which obstructed the main branch of the left coronary artery.
