A 47-year-old male with intermediate risk of coronary artery disease and atypical chest pain was referred to our hospital for multislice computed tomography (MSCT) coronary angiography. MSCT of the patient revealed apical interruption of myocardium and apical diverticulum (15x11 mm) of the left ventricle (Panels AF). The ECG of the patient was normal sinus rhythm, and the patient had no history of myocardial infarction.
Congenital diverticulum of the left ventricle is a rare cardiac malformation that frequently includes other congenital defects involving the abdominal wall, sternum, diaphragm, pericardium, and heart. Isolated left ventricular diverticulum is found in 30% of cases and is associated with numerous serious complications, such as cardiac arrhythmias, sudden death, endocarditis, systemic emboli, heart failure, cardiac rupture, and intraventricular obstruction. Surgical resection is the treatment of choice in symptomatic patients, whereas the management of asymptomatic patients often represents a therapeutic dilemma.
Panels A and B. Two-chamber MSCT views of left ventricle during diastole (Panel A) and systole (Panel B) demonstrating apical interruption of myocardium and apical diverticulum (15x11 mm) with nodular calcifications on the thinned wall.
Panels C and D. Post-processed three-dimensional rendered systolic images of left ventricle after extraction of myocardium demonstrating apical diverticulum resembling a tear drop falling from the heart.
Panels E and F. MSCT coronary angiography of the patient demonstrating normal coronary arteries (Panel E, left anterior descending artery; Panel F, proximal sections of coronary arteries).
