Journal of Cardiac Surgery

|November 1, 1993

Summary

This study introduces a novel cylindrical valve crafted from PTFE or porcine pericardium to prevent semilunar valve regurgitation. Clinical use in complex pediatric heart conditions demonstrated trivial regurgitation, offering advantages over artificial valves.

Background:

Semilunar valve regurgitation is a significant complication in pediatric cardiac surgery.
Existing prosthetic valves may have limitations in pediatric patients, including size constraints and compression issues.
Jatene's operation and total correction of tetralogy of Fallot can lead to truncal valve insufficiency.
