Background: New conduction disturbances are frequent after transcatheter aortic valve implantation (TAVI). Refining our ability to predict high-grade atrioventricular block (AVB) occurring later than 24 hours after the procedure would be useful in order to select patients eligible for early discharge.

Aims: This study was designed to identify predictors of high-grade AVB occurring between 24 hours and 30 days after TAVI and to develop and validate a predictive risk score.

: To date, data regarding the characteristics and management of obstructive, stable coronary artery disease (CAD) encountered in patients undergoing transcatheter aortic valve implantation (TAVI) are sparse. The aim of the study was to analyze granular details, treatment, and outcomes of patients undergoing TAVI with obstructive, stable CAD from real-world practice. : REVASC-TAVI (Management of myocardial REVASCularization in patients undergoing Transcatheter Aortic Valve Implantation with coronary artery disease) is an investigator-initiated, multicenter registry, which collected data from patients undergoing TAVI with obstructive stable CAD found during the pre-TAVI work-up.

Paravalvular regurgitation remains a frequent finding after transcatheter aortic valve replacement and is associated with unfavorable outcomes if more-than-mild grade. In this case, a patient underwent a third transcatheter aortic valve replacement procedure for worsening symptoms due to severe paravalvular regurgitation. The case underlines the role of preprocedural planning in achieving treatment success.

Background: Data on the likelihood of left ventricle (LV) recovery in patients with severe LV dysfunction and severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) and its prognostic value are limited.

Aims: We aimed to assess the likelihood of LV recovery following TAVI, examine its association with midterm mortality, and identify independent predictors of LV function.

Methods: In our multicentre registry of 17 TAVI centres in Western Europe and Israel, patients were stratified by baseline LV function (ejection fraction [EF] >/≤30%) and LV response: no LV recovery, LV recovery (EF increase ≥10%), and LV normalisation (EF ≥50% post-TAVI).

Article Synopsis
  • The study assesses the effectiveness of self-expanding (SE) Evolut PRO/PRO+ versus balloon-expandable (BE) SAPIEN ULTRA valves in patients with small aortic annuli, using data from the OPERA-TAVI registry.
  • It finds that the 1-year primary effectiveness outcomes are similar for both valve types, but the SE group shows better results for 30-day device-related outcomes.
  • The SE valves have higher rates of disabling strokes and paravalvular leaks, while the BE valves exhibit more issues with prosthesis-patient mismatch and elevated residual mean gradients.

Background: Coronary re-engagement after transcatheter aortic valve replacement (TAVR) using self-expanding transcatheter heart valves (THVs) systematically implanted using commissural alignment (CA) techniques has been poorly investigated.

Objectives: The aim of this study was to evaluate unsuccessful coronary cannulation, and its predictors, after TAVR using self-expanding devices implanted using CA techniques.

Methods: RE-ACCESS 2 (Reobtain Coronary Ostia Cannulation Beyond Transcatheter Aortic Valve Stent 2) was an investigator-driven, single-center, prospective study that enrolled consecutive TAVR patients receiving Evolut and ACURATE THVs implanted using CA techniques.

Evidence regarding gender-related differences in response to transcatheter aortic valve implantation according to the valve type is lacking. This study aimed to evaluate the impact of gender on the treatment effect of Evolut PRO/PRO+ (PRO) or SAPIEN 3 Ultra (ULTRA) devices on clinical outcomes. The Comparative Analysis of Evolut PRO vs SAPIEN 3 Ultra Valves for Transfemoral Transcatheter Aortic Valve Implantation (OPERA-TAVI) is a multicenter, multinational registry including patients who underwent the latest-iteration PRO or ULTRA implantation.

Article Synopsis
  • - The study compares 1-year clinical outcomes of TAVI patients using Evolut PRO/PRO+ and SAPIEN 3 Ultra devices, addressing a lack of midterm comparative analyses in current real-world practice.
  • - Using data from the OPERA-TAVI registry, 587 matched pairs of patients were analyzed, showing no significant difference in the primary endpoint (composite of death, disabling stroke, and rehospitalization), but higher rates of disabling stroke in the PRO group.
  • - Overall, while the clinical outcomes were similar between the two devices, patients receiving PRO experienced notably higher rates of disabling stroke, particularly within the first 30 days following the procedure.

Article Synopsis
  • The study investigates the best timing for performing percutaneous coronary interventions (PCI) in patients undergoing transcatheter aortic valve implantation (TAVI), a procedure for severe aortic stenosis with existing coronary artery disease (CAD).
  • An analysis of 1,603 patients from the REVASC-TAVI registry shows that performing PCI after TAVI leads to better 2-year clinical outcomes, with significantly lower rates of all-cause death and major complications compared to PCI before or concurrently with TAVI.
  • The findings suggest that scheduling PCI after TAVI may be more beneficial, but further confirmation through randomized clinical trials is needed.

Article Synopsis
  • The study assesses the management of stable coronary artery disease (CAD) in patients undergoing transcatheter aortic valve implantation (TAVI), highlighting inconsistencies in existing evidence.
  • Using data from the REVASC-TAVI registry with 2407 patients, researchers compared outcomes between those who underwent complete versus incomplete myocardial revascularization.
  • Findings indicate no significant differences in all-cause death or composite outcomes (like stroke and rehospitalization for heart failure) between the two groups after 2 years, suggesting that the completeness of revascularization may not impact outcomes for TAVI patients with stable CAD.

New insights into the natural history and pathophysiology of patients with aortic stenosis (AS), coupled with the dramatic evolution of transcatheter aortic valve implantation (TAVI), are fuelling intense interest in the management of asymptomatic patients with severe AS. This patient presenting for elective intervention poses a unique challenge. These patients are not traditionally offered surgical aortic valve replacement or TAVI given their lack of symptoms; however, they are at increased risk given the severity of their AS.

Background: The safety of concomitant percutaneous coronary intervention (PCI) during transcatheter aortic valve implantation (TAVI) setting is still highly debated. This study aimed to assess the safety and the effectiveness of TAVI and PCI performed in the same session compared with TAVI alone.

Methods: Patients with severe aortic stenosis and coronary artery disease (CAD) (N.

Background: The latest iterations of devices for transcatheter aortic valve replacement (TAVR) have brought refinements to further improve patient outcomes.

Objectives: This study sought to compare early outcomes of patients undergoing TAVR with the self-expanding (SE) Evolut PRO/PRO+ (Medtronic, Inc) or balloon-expandable (BE) Sapien 3 ULTRA (Edwards Lifesciences) devices.

Methods: The OPERA-TAVI (Comparative Analysis of Evolut PRO vs Sapien 3 Ultra Valves for Transfemoral Transcatheter Aortic Valve Implantation) registry collected data from 14 high-volume centers worldwide on patients undergoing TAVR with SE or BE devices.

Article Synopsis
  • A study conducted at a high-volume Italian center assessed changes in transcatheter aortic valve implantation (TAVI) practices and patient outcomes from June 2007 to August 2021, categorizing data into four time periods.
  • The analysis included 2058 patients with a mean age of 82, revealing a decrease in mortality risk and significant reductions in in-hospital deaths, major strokes, and complications over time.
  • Overall device success improved notably, with enhancements in patient outcomes attributed to advancements in technology and clinical practices in TAVI throughout the 15-year period.

Achieving patient-specific commissural alignment of transcatheter aortic valves is particularly important to ensure coronary reaccess after transcatheter aortic valve implantation. Nevertheless, in case of uncommon origin of coronary arteries, commissural alignment could be counterproductive. This case shows how alignment techniques could serve to intentionally misalign the neocommissures in this subset of patients.
