Isolated large true contractile left ventricular diverticulum mimicking ischemia in an adult patient: a case report.

Congenital diverticulum of the ventricle is a rare cardiac abnormality that is characterized by local embryologic development failure of the ventricular muscle. It can be found as an isolated form or associated with other cardiac abnormalities. Clinically, it has been reported that it can lead to heart failure, arrhythmia, or chest pain, although frequently the course is asymptomatic. We present a patient who was referred to our clinic with chest pain due to isolated left ventricular diverticulum mimicking myocardial ischemia.
