AI Article Synopsis
- Transcatheter aortic valve implantation (TAVI) is a procedure for treating severe aortic stenosis, particularly in patients at intermediate to high risk for traditional open-heart surgery.
- This less invasive method can lead to complications, especially intraventricular conduction disorders, affecting over 75% of patients post-procedure.
- Certain factors, like existing right bundle branch block, along with structural characteristics like a smaller aortic annulus and porcelain aorta, increase the likelihood of needing a permanent pacemaker after TAVI.
Article Abstract
Transcatheter aortic valve implantation (TAVI) is indicated in severe symptomatic aortic stenosis, when there is intermediate-high surgical risk, or a condition considered inoperable, as in the case of "porcelain aorta" that could turn clamping or cannulation of the ascending aorta hazardous in open-heart surgery. Among the complications of this less invasive procedure, intraventricular conduction disorders subsequent to the procedure stand out. TAVI causes worsening of intraventricular dromotropic disorders in more than 75% of the cases, with the presence of preexisting right bundle branch block and first-degree atrioventricular block, deep prosthesis implant, male gender, size of the aortic annulus smaller than the prosthesis, and porcelain aorta being predictive of requirement for permanent pacemaker implant.

Real-world application of CCTA with CT-FFR for coronary assessment pre-TAVI: the CT2TAVI study.
Int J Cardiovasc Imaging

Cardiology, Endeavor NorthShore Cardiovascular Institute, Evanston, IL, USA.
This study aims to evaluate the implementation of concomitant CAD assessment on pre-TAVI (transcatheter aortic valve implantation) planning CTA (CT angiography) aided by CT-FFR (CT-fractional flow reserve) [The CT2TAVI protocol] and investigates the incremental value of CT-FFR to coronary CT angiography (CCTA) alone in the evaluation of patients undergoing CT2TAVI. This is a prospective observational real-world cohort study at an academic health system on consecutive patients who underwent CTA for TAVI planning from 1/2021 to 6/2022. This represented a transition period in our health system, from not formally reporting CAD on pre-TAVI planning CTA (Group A) to routinely reporting CAD on pre-TAVI CTA (Group B; CT2TAVI protocol).

BACKGROUND Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure increasingly used to treat severe aortic stenosis, especially in elderly patients and those with significant comorbidities who are at high risk for surgical intervention. While TAVR is generally safe and effective, rare complications can occur, including cerebral air embolism, which can result in acute neurological deficits. This report presents the case of a 75-year-old man who developed a cerebral air embolism following TAVR.

Background: The optimal timing for percutaneous coronary intervention (PCI) in patients undergoing transcatheter aortic valve replacement (TAVR) is debatable.
Objectives: The aim of this study was to compare outcomes based on the timing of PCI in stable coronary artery disease patients undergoing TAVR.
Methods: Leveraging the STS/ACC TVT Registry and Medicare Linkage, we analyzed patients with stable coronary artery disease undergoing PCI and TAVR between 2015 and 2023 using the SAPIEN 3 balloon-expandable valve platform.

Background: The prevalence of coronary artery disease in patients undergoing transcatheter aortic valve replacement (TAVR) is high. Treatment of a coronary events (CE) after TAVR can be technically challenging.
Objectives: The authors sought to assess the incidence and prognostic impact of CE after TAVR.

Transcatheter aortic valve-in-valve replacement presents a viable, minimally invasive approach to replacing degraded bioprosthetic surgical valves. The major drawback of this technique is poor hemodynamics in the form of patient-prosthesis mismatch and high transvalvular gradients. This is commonly attributable to the reduced valvular diameter from the transcatheter heart valve fixed inside the degraded bioprosthesis.
