Application of double coronary artery guide-wires for establishing complex pathway of interventional therapy for congenital heart diseases / 中国介入影像与治疗学

ABSTRACT

Objective: To explore the application value of double coronary artery guide-wire method in establishment complex pathway of interventional therapy for congenital heart diseases (CHD). Methods: Clinical data of 12 children with CHD were retrospectively analyzed, including 5 patients with pulmonary artery stenosis after correction of pulmonary atresia with ventricular septal defect (PA/VSD), 1 with pulmonary artery stenosis after radical repair of tetralogy of Fallot (TOF), 1 with pulmonary artery stenosis after correction of transposition of great artery (TGA), 3 patients with pulmonary atresia with major aorta pulmonary collateral arteries (MAPCAs), 1 with complex pulmonary arteriovenous fistula (PAVF) and 1 with circumflex branch of left coronary artery-right atrial fistula. The characteristics of complex pathways for interventional treatment of CHD were analyzed. Results: The pathways were successfully established with double coronary artery guide-wires in all patients. Balloon intervention was successfully performed in patients with pulmonary artery stenosis after correction of PA/VSD, radical repair of TOF and TGA underwent. Patients with pulmonary atresia with MAPCAs, complex PAVF and circumflex branch of left coronary artery-right atrial fistula underwent successfully occlusion. No major complication, such as valvular injury, vascular injury, pericardial tamponade or death occurred. Conclusion: Double coronary artery guide-wire method is safe and effective for establishing complex pathway of interventional therapy for congenital heart diseases, which has strong flexibility and can provide sufficient support through tortuous pathway to improve the successful rate of intervention, therefore being worthy of clinical popularization and application.
