Background: Atrial fibrillation (AF) has been identified as a marker of advanced cardiac damage in aortic stenosis patients. However, the factors associated with poorer outcomes among AF patients in contemporary TAVR practice, particularly regarding mortality and heart failure (HF)-related hospitalizations, remain largely unknown.

Methods: Multicenter study including consecutive patients with a history of AF, evaluating the clinical outcomes and predictors of mortality, and HF-related hospitalization, who underwent TAVR with newer-generation devices using balloon or self-expandable valves.

Background: Cardiac surgery for infective endocarditis (IE) is associated with significant hospital mortality, and female sex may be associated with worse outcomes. However, the impact of sex on the presenting characteristics, management, and outcomes of patients operated on for acute infective endocarditis (IE) has not been adequately studied.

Objectives: The goal of our study was to analyse differences in management and outcome of IE between women and men who undergo surgery.

Background: There is currently no established recommendation for antithrombotic treatment following transcatheter mitral valve replacement (TMVR). However, based on the analogy with surgical mitral bioprosthesis, vitamin K antagonists (VKAs) are predominantly used.

Objectives: The purpose of this study was to compare bleeding and thrombotic events associated with direct oral anticoagulants (DOACs) or VKAs in a prospective cohort of TMVR patients.

Mitral regurgitation is the second most frequent heart valve disease in Europe and the most frequent in the US. Although surgery is the therapy of choice when intervention is indicated, transcatheter mitral valve repair or replacement are alternatives for patients who are not eligible for surgery. However, the development of transcatheter mitral valves is slower than expected.

Article Synopsis
  • This study examined the rates and causes of sudden cardiac death (SCD) and heart failure (HF)-related deaths in 5,421 patients who underwent transcatheter aortic valve replacement (TAVR) using newer devices.
  • Findings revealed that 18% of patients died within two years, with over half of those deaths attributed to cardiovascular issues, notably advanced HF and SCD.
  • Key predictors for HF-related death included atrial fibrillation and reduced heart function, while factors linked to increased SCD risk included certain procedural complications like periprocedural ventricular arrhythmias.*

Article Synopsis
  • Paravalvular leak (PVL), conduction disturbances, and vascular complications are key issues following Transcatheter Aortic Valve Replacement (TAVR), leading to the development of third-generation heart valves like SAPIEN 3 and EVOLUT PRO to reduce these problems.
  • A study involving 1,481 patients from six European centers found that SAPIEN 3 showed lower rates of PVL compared to EVOLUT PRO at various follow-up points, especially for low-grade PVL.
  • However, no significant difference in severe PVL or 1-year survival rates was observed between the two devices, indicating that while PVL detection is high, both devices have similar outcomes in terms of serious complications and survival.

Article Synopsis
  • This study investigates the incidence and effects of late bleeding events (LBEs) in patients who undergo percutaneous coronary intervention (PCI) before transcatheter aortic valve replacement (TAVR).
  • Among 1,457 patients analyzed, 7.9% experienced LBEs after TAVR, with various severities impacting long-term mortality rates.
  • It concludes that LBEs significantly heighten the risk of death after TAVR and highlights the need for effective strategies to prevent these events and optimize antithrombotic treatments.

Article Synopsis
  • The study compares infective endocarditis (IE) outcomes in patients after surgical aortic valve replacement (SAVR) versus transcatheter aortic valve replacement (TAVR), aiming to identify differences in clinical presentation, microbiological profiles, management, and outcomes.
  • Data was gathered from two international registries, focusing on patients with IE affecting aortic valve prostheses, and included a matched comparison of TAVR and SAVR patients.
  • The findings revealed that patients with surgical bioprostheses had higher rates of complications but similar one-year mortality rates compared to those with TAVR, indicating important differences in infection characteristics and treatment but comparable long-term outcomes.
