Double-chambered left ventricle in a patient with chest pain
- 111 Downloads
A 42-year-old man with atypical chest pain was admitted to hospital. He had no health problems until that time. At presentation, the electrocardiogram showed sinus rhythm at 84 beats per minute, along with left bundle branch block (Fig. 1). Echocardiographic studies revealed a reduced left ventricular ejection fraction of 39% and an unusual, aneurysm-like structure adjacent to the lateral wall of the left ventricle. Coronary angiography ruled out coronary artery disease. Left ventricular angiography confirmed the aneurysm-like outpouching of the lateral wall of the left ventricle (Fig. 2) and the reduced ejection fraction.
