Utility of guide catheter extension and intravascular ultrasound to facilitate transcatheter device closure of aortic paravalvular leak.
Signal observed regarding transcatheter closure techniques for aortic paravalvular leaks using guide catheter extension and intravascular ultrasound guidance in adult patients. Evidence suggests these adjunctive techniques, typically employed in coronary interventions, can facilitate complex structural heart interventions. Worth noting the expansion of transcatheter approaches for valve-related complications, though this case involves adult aortic valve pathology rather than congenital heart disease.
This report illustrates that these adjunctive techniques, more commonly used in coronary angioplasty procedures, can be used to enable complex PVL closure.
Relevance: While this addresses transcatheter structural heart intervention techniques, it focuses on adult aortic paravalvular leak repair rather than the pediatric congenital heart conditions in the practice profile (HLHS, TOF, TGA, Fontan, Kawasaki).
