Double-chambered right ventricle in an adult patient.

: A 65-year-old male was referred for to our facility for right and left heart catheterization and coronary angiography for evaluation of a ventricular septal defect and to rule out significant coronary artery disease. During the procedure, the patient was diagnosed with a double-chambered right ventricle (DCRV). Most DCRV cases are diagnosed at a young age; presentation in an adult is extremely rare.
