Echocardiography plays a key role in imaging and guiding transcatheter closure of left-sided prosthetic paravalvular regurgitation.
Paravalvular leak (PVL) is a complication related to the surgical implantation of left-sided prosthetic valves. The prevalence of paravalvular regurgitation ranges between 5 and 20%. Left-sided prosthetic paravalvular regurgitation presents with a wide constellation of signs and symptoms ranging from asymptomatic murmur to heart failure, hemolysis and cardiac cachexia. Echocardiography plays a key role in imaging the PVL and can help in guiding the closure procedure with both transesophageal and intracardiac probes. Transcatheter closure of paravalvular regurgitations is an appealing prospect.
