Insights
Intraoperative thermal coronary angiography effectively identified coronary ostial obstruction in 9 patients undergoing congenital heart defect repair. This technique enables early detection and surgical correction, improving outcomes for complex pediatric cardiac surgeries.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Medical Imaging
Background:
- Congenital heart defects require complex surgical correction.
- Coronary ostial obstruction is a potential complication during these procedures.
- Accurate intraoperative assessment of coronary arteries is crucial.
Purpose of the Study:
- To evaluate the utility of intraoperative thermal coronary angiography.
- To assess its effectiveness in detecting coronary ostial obstruction.
- To determine its role in guiding surgical correction of congenital heart defects.
Main Methods:
- Intraoperative thermal coronary angiography was performed on 9 patients.
- Patients underwent various congenital heart defect repairs, including arterial switch, Ross operation, and anomalous left coronary artery reimplantation.
- The technique was used to visualize coronary ostia during surgery.
Main Results:
- The procedure was successfully applied in all 9 patients.
- Early detection of coronary ostial obstruction was achieved.
- The findings facilitated timely surgical intervention.
Conclusions:
- Intraoperative thermal coronary angiography is a valuable tool for congenital heart defect surgery.
- It enables prompt identification and management of coronary ostial obstruction.
- This technique can improve surgical outcomes in pediatric cardiac patients.
Abstract:
Intraoperative thermal coronary angiography was successfully applied in 9 patients who underwent operative correction of congenital heart defects: arterial switch operation for transposition of the great arteries (n = 5), Ross operation for valvar aortic stenosis with regurgitation (n = 3), and aortic implantation of the left coronary artery for anomalous connection of the left coronary artery to the pulmonary artery (n = 1). Intraoperative thermal coronary angiography allows early detection and surgical correction of coronary ostial obstruction.
