Surgical treatment of patients with transposition of the great arteries

Area of Science:

• Pediatric Cardiology
• Congenital Heart Disease Surgery
• Cardiac Electrophysiology

Background:

• Infant prognosis for transposition of the great arteries has significantly improved.
• Established diagnostic and treatment principles exist, but optimal surgical timing and techniques remain debated.
• Obstructive complications and post-operative dysrhythmias are key concerns following corrective surgery.

Purpose of the Study:

• To evaluate the optimal age for elective Mustard operation.
• To identify surgical techniques that minimize obstructive complications and post-operative dysrhythmias.
• To correlate surgical phases of the Mustard operation with electrophysiological findings.

Main Methods:

• Review of surgical techniques used in 143 Mustard operations performed since 1973.
• Electrophysiological studies conducted during various phases of the Mustard operation.
• Analysis of outcomes focusing on complications and arrhythmias.

Main Results:

• Data from 143 Mustard operations provide insights into surgical technique efficacy.
• Electrophysiological studies offer a deeper understanding of cardiac function during and after the procedure.
• The study addresses uncertainties regarding the optimal timing and technical aspects of the Mustard operation.

Conclusions:

• The findings contribute to refining the Mustard operation for transposition of the great arteries.
• Improved surgical techniques and understanding of electrophysiology can reduce adverse outcomes.
• This research aids in optimizing the management of infants with this congenital heart defect.
