Why the study?
Paravalvular leak is a TAVR complication linked to increased mortality, but TEE, TTE, and angiography may misrepresent eccentric regurgitation as paravalvular leak.
Does intracardiac echocardiography (ICE) accurately differentiate post-TAVR eccentric valve insufficiency from paravalvular leak compared to standard imaging modalities?
Does intracardiac echocardiography (ICE) accurately differentiate post-TAVR eccentric valve insufficiency from paravalvular leak compared to standard imaging modalities?
Intracardiac echocardiography can serve as a valuable adjunctive imaging tool to accurately distinguish eccentric transvalvular regurgitation from paravalvular leak following TAVR.
ICE may clarify post-TAVR regurgitation sources when standard imaging is inconclusive; hypothesis-generating and requires prospective validation.
•TAVR has become a prevalent procedure.•PVL is a complication of TAVR with increased risk for mortality.•TEE, TTE, and angiography may misrepresent TAVR eccentric regurgitation for PVL.•ICE may be used to distinguish TAVR regurgitation.
