Expanding indications for pediatric coronary artery bypass

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Vascular Biology

Background:

• Pediatric coronary artery bypass surgery is primarily performed for Kawasaki disease complications.
• Limited data exists on the feasibility and outcomes of internal thoracic artery-coronary artery bypass in infants and children.

Purpose of the Study:

• To review the clinical experience of internal thoracic artery-coronary artery bypass in pediatric patients.
• To assess the feasibility of this procedure by analyzing angiographic measurements in a control cohort.
• To evaluate graft patency and perioperative outcomes.

Main Methods:

• Retrospective review of six pediatric patients undergoing internal thoracic artery-coronary artery bypass (1987-1994).
• Analysis of angiographic data from 34 control pediatric patients (1 day to 16.1 years) to assess vessel size.
• Assessment of graft patency via postoperative angiography and Doppler echocardiography.

Main Results:

• All six pediatric patients survived the surgery without perioperative myocardial infarction.
• Graft patency was confirmed in five patients post-surgery via angiography and in one via Doppler echocardiography.
• Angiographic measurements indicated that internal thoracic and coronary arteries are proportionally large in neonates and infants.

Conclusions:

• Internal thoracic artery-coronary artery bypass is a feasible and potentially life-saving procedure for pediatric patients with diverse cardiac indications.
• The procedure should be considered for expanding indications and emergency intraoperative situations.
• Further studies are needed to determine long-term graft patency and reoperation rates.
