This article examines the impact of interventricular septal hypertrophy on acute outcomes after transcatheter aortic valve implantation (TAVI). The study analyzed data from 1,033 patients who underwent TAVI between 2009 and 2021. The results showed that patients with increased interventricular septal depth (IVSD) did have higher transvalvular pressure gradients after the procedure, but there were no significant differences in composite endpoints, technical success, paravalvular leakage, permanent pacemaker implantation, or 30-day mortality between patients with normal IVSD and increased IVSD. However, the long-term effects of these hemodynamic differences on valve durability require further investigation. [Extracted from the article]

This article examines the long-term outcomes of patients with severe pulmonary hypertension (PH) who undergo transcatheter aortic valve implantation (TAVI). The study analyzed data from 3610 patients who underwent TAVI, with 456 patients identified as having severe PH. The results showed that patients with severe PH had distinct baseline characteristics and higher rates of adverse events, including acute kidney injury, major bleeding, and higher mortality rates. The presence of severe PH was also associated with increased rates of complications such as bleeding, pacemaker implantation, and renal failure. [Extracted from the article]

This article discusses the challenges and outcomes of transcatheter aortic valve implantation (TAVI) in patients with extra small aortic annuli, specifically those with a diameter of ¿20.5 mm. The study analyzed data from 93 patients with small aortic annuli who underwent TAVI between 2011 and 2021. The results showed that TAVI in this patient subset had impaired acute outcomes, with higher rates of mortality, stroke, and elevated transvalvular gradients. The authors suggest that surgical aortic valve replacement with aortic root enlargement should be considered for these patients whenever feasible and clinically acceptable.

This article discusses the long-term outcomes of valve-in-ring (ViR) and valve-in-valve (ViV) procedures for failing mitral annuloplasty rings and bioprosthetic valves. The study analyzed data from 51 patients who underwent these procedures between 2014 and 2023. The results showed that the procedures had a reasonable safety and durability profile up to 5 years, with an overall survival rate of 87.5% and 83.4% after ViR and ViV, respectively. However, there were cases of significant paravalvular leakage in patients with rigid annuloplasty rings, which required additional leakage closure. The study also noted a shift from the transapical to the transseptal approach over the last decade, reducing procedural trauma. [Extracted from the article]

This article discusses the use of Surgical Aortic Valve Replacement (SAVR) in elderly patients. The study compared patients under 75 years of age to those over 75 years of age who underwent SAVR. The results showed that both age groups had low rates of mortality, stroke, and permanent pacemaker implantation, despite a significant proportion of patients with infective endocarditis. The authors suggest that the decision to use SAVR or Transcatheter Aortic Valve Implantation (TAVI) should be based on various factors, including anatomical parameters and clinical condition.
