Paravalvular leak is complication derived from incomplete sealing between the implanted prosthesis and the native annulus, which occurs in 5% of all patients who undergo mitral valve replacement and 10% of those who undergo transcatheter aortic valve replacement. This is the most frequent non-structural valve dysfunction. While mild leaks can be asymptomatic, moderate to severe...
Courtesy of Dr. Carlos Fava. The association between diastolic dysfunction (DD) and aortic insufficiency (AI) after transcatheter aortic valve replacement (TAVR) has not been studied yet, but the presence of aortic regurgitation has proved to be associated with worse outcomes. A total of 144 out of 195 patients who underwent TAVR with balloon-expandable SAPIENS or SAPIENS XT...
Aortic stenosis is an increasingly common valvulopathy because people are living longer now. A present, the main treatment consists of surgical (SAVR) or transcatheter aortic valve replacement. (TAVR). One of the main challenges of this disease is its progression. The European guidelines recommend Doppler echocardiograms every 2 to 3 years for mild cases, mildly calcified,...
Aortic stenosis (AS) is classified according to gradient into high flow and high gradient (D1), low flow-low gradient with reduced ejection fraction (D2), and paradoxical low flow-low gradient with conserved ejection fraction (D3). D3 AS is characterized by ≥50% ejection fraction, but with systolic volume index ≤35 ml/min. Post TAVR evolution of D2 and D3...
The prevalence of tricuspid regurgitation (TR) is significant; its prognosis is well known, and severe TR stages are associated with higher mortality and hospitalization for cardiac failure (CF). Seeing as valve disease tends to evolve over time, in advanced stages, we usually check on patients at specified intervals for early identification of potential hemodynamic complications...
The progression of aortic stenosis has been extensively studied and is well-known. As observed, in its advanced stages, this condition entails high morbidity and a marked decrease in survival. Both North American and European guidelines recommend treatment when faced with severe valve disease. However, true severity can be difficult to determine due to discordant data,...
The presence of cardiogenic shock (CS) in a setting of aortic stenosis ranges from 1% to 4%. The prognosis for this scenario is ominous due to subendocardial ischemia, which presents as a decrease in ventricular preload and an increase in afterload. Aortic valvuloplasty has been used in this context, but, unfortunately, it has been associated...
The second group of Women Interventionists sponsored by SOLACI has started the training on structural disease as part of our scholarship program at the Instituto Cardiovascular de Rosario (ICR). The program will take place over the course of this week in different centers across Argentina. During the session, the grant holders were able to attend...
Moderate aortic stenosis (MAS) encompasses a broader spectrum than severe aortic stenosis. However, its progression has not yet been fully elucidated. While there are reports suggesting that this condition is not as benign as initially believed, there is a need to consider early interventions in certain instances. Researchers conducted an analysis from January 2016 to...
TAVR has been shown beneficial in patients across the risk spectrum. The PARTNER 2 SAPIEN 3 (P2S3i) study on intermediate risk patients was the first to show TAVR superiority vs SAVR when using the transfemoral approach. SAVR durability has been shown in different analysis but, except for a few reports, TAVR durability at long term...
