Summary
This case report details the surgical management of a 59-year-old man with double-chambered right ventricle. Successful surgical repair relieved symptoms and preserved right ventricular function, highlighting the importance of surgical approach selection.
Area of Science:
- Cardiology
- Cardiac Surgery
- Congenital Heart Disease
Background:
- Double-chambered right ventricle (DRCV) is a rare congenital heart defect characterized by anomalous muscle bundles dividing the right ventricle into two chambers.
- Patients may remain asymptomatic until adulthood, presenting with heart failure due to the pressure gradient across the divided ventricle.
Observation:
- A 59-year-old male presented with heart failure attributed to DRCV with a perimembranous ventricular septal defect.
- Cardiac catheterization revealed a significant pressure gradient (approximately 80 mmHg) within the right ventricle, with normal pulmonary artery pressures.
Findings:
- Surgical repair using right ventriculotomy was performed to alleviate the pressure gradient and resolve the patient's symptoms.
- Postoperative assessment confirmed preserved right ventricular function, indicating a successful surgical outcome.
Implications:
- The choice between a right ventriculotomy and a transatrial approach is critical for complete relief of the pressure gradient in DRCV.
- This case underscores the importance of timely surgical intervention for symptomatic DRCV to prevent irreversible cardiac damage.
