Methods for repair of simple isolated ventricular septal defect

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Congenital Heart Disease

Background:

• Ventricular septal defects (VSD) are common congenital heart abnormalities.
• Surgical repair is often necessary to correct VSDs and prevent complications.
• Minimally invasive techniques aim to reduce surgical risks and improve outcomes.

Purpose of the Study:

• To evaluate the safety and efficacy of surgical repair for isolated simple ventricular septal defects (VSD).
• To describe various surgical approaches and techniques for VSD closure.
• To assess the long-term outcomes of VSD repair without ventriculotomy.

Main Methods:

• Retrospective analysis of 115 consecutive patients undergoing VSD repair from 1985-1989.
• Surgical techniques included transatrial, transaortic, and transpulmonary approaches.
• Detailed description of methods to manage tricuspid valve issues and enhance VSD exposure.

Main Results:

• No ventriculotomy was required for VSD closure in any patient.
• Zero instances of permanent atrioventricular dissociation were reported.
• No reoperations for residual or recurrent VSD were necessary.
• Postoperative echocardiographic and Doppler studies confirmed good surgical results.
• One hospital death occurred.

Conclusions:

• Surgical repair of isolated simple VSDs can be safely accomplished without ventriculotomy.
• Specific technical strategies enhance VSD exposure and facilitate repair.
• The described methods lead to favorable surgical outcomes and low complication rates for VSD closure.
