Till recently, the only way to treat paravalvular
leak was to redo surgery and re-suturing.
Of particular significance in the findings is the absence of explants due to structural valve deterioration, as well as the low rate of paravalvular
For the demo, the team performed a highly technically demanding procedure known as paravalvular
aortic leak closure, which repairs replacement heart valves that have begun leaking around the edges.
It features a braided valve frame and an adaptive seal that minimizes paravalvular
regurgitation or leaking (PVL) by conforming to the patient's native aortic valve.
The LOTUS Valve System features an adaptive seal, which creates an external seal to prevent leakage around the valve known as paravalvular
leak or PVL, a proven predictor of mortality.
Echocardiography showed minimal anterior paravalvular
Prosthetic valve endocarditis may present with new valvular regurgitation, dehiscence of prosthetic valve, and intracardiac mass of paravalvular
abscess [4, 7, 8].
An echocardiogram revealed dilatation of the ascending aorta and mild paravalvular
leak around the bioprosthetic aortic valve.
There were no signs of paravalvular
abscesses and no stenosis of the affected valve.
Secondary endpoints included (1) incidence of major bleeding (including operative revision), (2) incidence of pacemaker implantation, (3) incidence of paravalvular
leakage, (4) procedural times, and (5) the length of hospital stay.
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.
