Left ventricular diverticulum repair in a newborn.

Area of Science:

• Pediatric Cardiology
• Congenital Heart Disease Surgery
• Cardiac Surgery

Background:

• Left apical diverticulum is a rare congenital cardiac anomaly.
• It can lead to severe complications such as heart failure and ventricular arrhythmias.
• Surgical intervention is often necessary for symptomatic cases.

Observation:

• A male newborn presented with a huge left apical diverticulum.
• Progressive heart failure and extensive ventricular arrhythmia were noted.
• The infant required surgical repair at 11 days of age.

Findings:

• A modified Dor procedure was successfully performed using an autologous endoventricular pericardial patch.
• Postoperative assessment showed a significant reduction in ventricular extrasystoles.
• One-year follow-up revealed normal cognitive and somatic development without cardiac failure signs.

Implications:

• The modified Dor procedure is an effective surgical option for left apical diverticulum.
• Early surgical repair can prevent severe cardiac complications and ensure normal development.
• This case highlights successful management of a complex congenital heart defect.
