Cardiopulmonary bypass in the presence of uncorrected coarctation
Insights
This study shows that intracardiac repair with aortic perfusion is a safe alternative for patients with coarctation and other heart defects. It avoids the need for separate coarctation repair or combined procedures.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
Background:
- Coarctation of the aorta often coexists with other congenital heart defects.
- Surgical correction of these associated defects can be complex.
- The role of isolated intracardiac repair with aortic perfusion in patients with coarctation needs further evaluation.
Purpose of the Study:
- To evaluate the safety and efficacy of intracardiac repair with aortic perfusion in patients with coarctation and other cardiovascular lesions.
- To determine if this approach is a viable alternative to traditional coarctation repair or combined procedures.
Main Methods:
- Retrospective analysis of 10 patients with coarctation and other intracardiac lesions.
- All lesions were repaired except coarctation, with arterial perfusion via the ascending aorta.
- Monitoring of urine output during cardiopulmonary bypass.
Main Results:
- No morbidity associated with cardiopulmonary bypass or lower body perfusion.
- No instances of left ventricular failure.
- One patient with Taussig-Bing abnormality and pulmonary vascular disease died postoperatively due to right ventricular failure.
Conclusions:
- Intracardiac repair with aortic perfusion is a safe alternative in the presence of coarctation.
- This approach can be considered when coarctation repair is not performed or combined procedures are not feasible.
- Careful patient selection is crucial, especially in complex cases with pulmonary vascular disease.
Abstract:
We performed correction of intracardiac lesions in 10 patients with coarctation. All cardiovascular lesions were corrected except coarctation. Six patients had a large left-to-right shunt though a ventricular septal defect (VSD), two patients had left ventricular outflow obstruction, two patients had mitral insufficiency, and one patient had mitral stenosis. Arterial perfusion was through the ascending aorta. Urine output was 6.0 +/- 1.5 cc/kg/hr during cardiopulmonary bypass. There was no morbidity related to cardiopulmonary bypass or inadequate perfusion of the lower body, and left ventricular failure did not occur. One patient with Taussig-Bing abnormality and pulmonary vascular disease died postoperatively of right ventricular failure. Intracardiac repair with aortic perfusion in the presence of coarctation is a safe alternative to coarctation repair or combined procedures.
