Summary
One and a half ventricular repair offers a promising surgical option for late-presenting Ebstein's anomaly patients with compromised ventricular function. This innovative approach significantly improves cyanosis, heart failure symptoms, and overall cardiac function.
Area of Science:
- Cardiology
- Congenital Heart Disease Surgery
Background:
- Ebstein's anomaly presenting late often involves severe right ventricular dysfunction, atrial enlargement, and tricuspid regurgitation.
- Conventional repair in such cases is associated with high mortality, morbidity, and suboptimal functional outcomes.
Observation:
- Three patients (8, 16, 35 years) with advanced Ebstein's anomaly underwent one and a half ventricular repair.
- The procedure included atrial septal defect closure, tricuspid valve repair, and superior vena cava to right pulmonary artery anastomosis.
Findings:
- All patients survived the surgery with a mean follow-up of 33 months.
- Complete resolution of cyanosis and heart failure symptoms was observed.
- Postoperative echocardiography revealed reduced tricuspid regurgitation and improved left ventricular function.
Implications:
- One and a half ventricular repair is a viable strategy for selected Ebstein's anomaly patients with compromised biventricular function.
- This technique can lead to significant functional recovery and improved quality of life.
