Single-Center Experience With the Senning Procedure in the Current Era

Area of Science:

• Cardiology
• Pediatric Cardiac Surgery
• Congenital Heart Disease

Background:

• The Senning procedure is a surgical technique for atrial inversion used in treating congenital heart anomalies.
• Evaluating contemporary outcomes of the Senning procedure is essential for refining surgical strategies.

Purpose of the Study:

• To assess the outcomes of the Senning procedure in patients with congenital heart anomalies.
• To identify factors influencing outcomes, particularly in patients with congenitally corrected transposition of the great arteries (cc-TGA).

Main Methods:

• A retrospective analysis of 19 patients who underwent the Senning procedure between August 2005 and July 2014.
• Review of hospital records and follow-up data to evaluate operative results and long-term outcomes.

Main Results:

• The Senning procedure demonstrated excellent systemic and pulmonary venous baffle patency with no observed obstruction during follow-up.
• Overall operative mortality was 5%, with 26% of patients developing heart block requiring pacemaker implantation.
• Actuarial survival was 81% at 5 years, though patients with cc-TGA experienced significant early mortality and left ventricular dysfunction after subsequent procedures.

Conclusions:

• The Senning procedure is effective in maintaining baffle patency for congenital heart anomalies.
• Outcomes in cc-TGA patients undergoing Senning-Rastelli or double switch operations require careful consideration due to higher mortality and morbidity.
• Surgical planning and patient selection are critical for optimizing results in complex congenital heart disease cases treated with the Senning procedure.
