Echocardiography showed minimal anterior paravalvular
6% rate of moderate paravalvular
leak among patients and zero incidents of severe paravalvular
Patients with a clinical diagnosis of IE had undergone transthoracic echocardiography (TTE) to diagnose echocardiographic evidence of infection namely vegetations, paravalvular
extension, prosthetic valve dehiscence, check haemodynamic compromise based on valvular dysfunction, ventricular dimensions and ventricular ejection fraction.
Perceval provided safe clinical and hemodynamic outcomes, and showed a statistically significant reduction in paravalvular
leakage and early mortality.
The Lotus Valve Adaptive Seal creates an external seal to prevent leakage known as paravalvular
leak or PVL, a proven predictor of mortality (1,3)
Transthoracic echocardiogram showed paravalvular
leaks around the bioprosthetic aortic valve with moderate to severe aortic insufficiency (AI), a dilated left ventricle (LV) and additional blood flow originating at the level of the aortic valve communicating with the right atrium (RA).
Postoperative Transthoracic Echoecardiography (TTE) or Trans Esophageal Echocardioraphy (TEE) were performed to exclude the possibility of recurrent vegetations or paravalvular
complications and associated late complications were higher in TAVR group.

Se le hizo ecocardiografia transesofagica, en la que se evidencio valvula aortica bicuspide (figura 4 panel A) con lesion vegetante, movil, en la valva anterior, con extension a la luz aortica en sistole y regurgitacion a la cavidad ventricular izquierda en diastole (figura 4 panel A), acompanada de lesion sacular paravalvular
, con comunicacion a la luz aortica, correspondiente a la formacion de pseudoaneurisma (panel B).
For example, the new valves contain a different outer material that is designed to better reduce paravalvular
CardiAQ's second generation TMVI products are built upon the company's proprietary method for anchoring the implant through leaflet engagement, chordal preservation, and annular attachment, while offering greater durability, improved flow properties, and a novel feature for the prevention of paravalvular
leaks, said Arshad Quadri, MD, Cardiac Surgeon, Founder, and CMO.
