Antegrade left heart catheterization
Insights
Antegrade left heart catheterization offers a safer alternative to traditional retrograde arterial catheterization for pediatric cardiac evaluations. This novel approach avoids arterial puncture complications and is effective even in complex cases.
Area of Science:
- Pediatric Cardiology
- Interventional Cardiology
- Vascular Access
Background:
- Retrograde arterial catheterization is the standard for left ventricular and systemic arterial evaluation.
- Arterial puncture carries inherent risks and complications.
Purpose of the Study:
- To report an alternative antegrade left heart catheterization technique.
- To evaluate its feasibility and safety in pediatric patients.
Main Methods:
- Cardiac catheterization via femoral vein in 18 children with interatrial communications.
- A balloon-tipped catheter was advanced in a "clockwise" fashion through the left atrium and ventricle into the aorta.
Main Results:
- The antegrade maneuver was successful and rapid in 17 of 18 children.
- The technique was feasible in an infant with hypoplastic left ventricle and used for renal arteriography.
Conclusions:
- Antegrade left heart catheterization circumvents arterial puncture complications.
- This approach is advantageous in pediatric patients, including those with coarctation of the aorta.
Abstract:
Retograde arterial catheterization has been the standard approach to hemodynamic and angiographic evaluation of the left ventricle and systemic arterial system. An alternative approach--antegrade left heart catheterization--is reported that circumvents arterial puncture. During cardiac catheterization from the femoral vein in 18 children with normally related great arteries who had interatrial communications, a balloon-tipped catheter was looped in a "clockwise" fashion through the left atrium and left ventricle and into the ascending aorta. In 17 children the maneuver was rapidly accomplished without complications; it proved possible to perform in an infant with a hypoplastic left ventricular cavity, and was employed to perform a renal arteriogram. The major advantage of antegrade left heart catheterization is avoidance of complications related to arterial puncture. The antegrade approach also avoids right arm cut-down in children with coarctation of the aorta.
