Insights
Congenital ventricular diverticulum, a rare heart defect, was incidentally found in a 57-year-old man during cardiac catheterization. Further imaging confirmed a muscular type diverticulum, ruling out other cardiac conditions.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Imaging
Background:
- Congenital ventricular diverticulum is an exceptionally rare congenital cardiac malformation.
- The condition can be asymptomatic or present with various cardiovascular symptoms.
Purpose of the Study:
- To report a case of incidentally discovered congenital left ventricular diverticulum.
- To highlight the diagnostic utility of advanced imaging modalities in characterizing this rare anomaly.
Main Methods:
- Case presentation of a 57-year-old male with suspected unstable angina.
- Diagnostic workup included cardiac catheterization, coronary CT, and cardiac MRI.
Main Results:
- Cardiac catheterization revealed no coronary artery disease.
- Incidental finding of a left ventricular diverticulum.
- Coronary CT and cardiac MRI confirmed a muscular type diverticulum and excluded a post-ischemic etiology.
Conclusions:
- Congenital ventricular diverticulum can be an incidental finding during cardiac investigations.
- Multimodality imaging is crucial for accurate diagnosis and differentiation from acquired conditions like aneurysms.
Abstract:
Congenital ventricular diverticulum is a rare cardiac malformation. We present the case of a 57-year-old man who underwent cardiac catheterization for suspected unstable angina. No coronary artery disease was diagnosed and a left ventricular diverticulum was incidentally found. Coronary CT and cardiac MRI were performed in order to confirm the diagnosis of a muscular type diverticulum and to exclude a post-ischemic aneurysm.
