Coronary artery bypass grafting for coronary artery stenosis caused by Kawasaki disease

Area of Science:

• Cardiology
• Pediatric Surgery
• Vascular Surgery

Background:

• Kawasaki disease can lead to coronary artery aneurysms requiring surgical intervention.
• Coronary artery bypass grafting (CABG) prevalence in Kawasaki disease patients is low (0.3-0.5% in Japan).
• Understanding lesion characteristics and natural history is key for surgical timing.

Purpose of the Study:

• To determine optimal timing and criteria for CABG in Kawasaki disease patients.
• To evaluate the long-term outcomes and graft patency after CABG for Kawasaki disease.
• To identify factors influencing prognosis and quality of life post-CABG.

Main Methods:

• Analysis of patient data undergoing CABG for Kawasaki disease.
• Assessment of coronary arterial lesion characteristics and natural history.
• Evaluation of graft patency and left ventricular ejection fraction post-surgery.

Main Results:

• CABG is indicated only when native coronary flow is severely impaired.
• Internal thoracic artery graft patency exceeds 20 years if good flow is confirmed at 1 year.
• Post-CABG left ventricular ejection fraction correlates with patient outcomes.

Conclusions:

• Optimal CABG timing and technique are essential for Kawasaki disease patients.
• Successful revascularization, particularly to the left coronary artery, improves prognosis and quality of life.
• Long-term graft patency is achievable with appropriate surgical management.
