Late Third Transcatheter Aortic Valve Replacement for Treatment of Persistent Paravalvular Regurgitation.

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.

Coronary Cannulation Following TAVR Using Self-Expanding Devices With Commissural Alignment: The RE-ACCESS 2 Study.

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.

Pre-TAVI imaging: an Italian survey by the CT PRotocol optimization (CT-PRO) group.

Purpose: The purpose of this survey was to evaluate the current state-of-art of pre-TAVI imaging in a large radiological professional community.

Methods: Between December 2022 and January 2023 all members of the Italian Society of Medical and Interventional Radiology (SIRM) were invited by the CT PRotocol Optimization group (CT-PRO group) to complete an online 24-item questionnaire about pre-TAVI imaging.

Results: 557 SIRM members participated in the survey.

Transcatheter aortic valve implantation during COVID-19 pandemic: An optimized model to relieve healthcare system overload.

Background: The coronavirus 2019 (COVID-19) pandemic upset healthcare systems and their logistics worldwide. We sought to assess safety and effectiveness of an optimized logistics for transcatheter aortic valve implantation (TAVI) pathway developed during the COVID-19 pandemic.

Methods: This is a retrospective analysis.

[Aortic valve papillary fibroelastoma and anomalous origin of the right coronary artery].

We report a case of a 48-year-old man who complained episodes of angina at rest. Instrumental investigation demonstrated a mass involving the ventricular side of the aortic valve suggestive for papillary fibroelastoma; an anomalous origin of the right coronary artery from the left sinus of Valsalva and no significant coronary artery disease were shown as well. The patient underwent open heart surgery, the tumor was excised and the aortic valve was spared.

Coronary Cannulation After Transcatheter Aortic Valve Replacement: The RE-ACCESS Study.

Objectives: The aims of this study were to investigate the feasibility of coronary ostia cannulation after transcatheter aortic valve replacement (TAVR) and to assess potential predictors of coronary access impairment.

Background: Certain data concerning the feasibility and reproducibility of coronary cannulation after TAVR are lacking.

Methods: RE-ACCESS (Reobtain Coronary Ostia Cannulation Beyond Transcatheter Aortic Valve Stent) was an investigator-driven, single-center, prospective, registry-based study that enrolled consecutive patients undergoing TAVR using all commercially available devices.

Usefulness of contrast injection during balloon aortic valvuloplasty before transcatheter aortic valve replacement: a pilot study.

Aims: To describe a technique of simultaneous aortography and balloon aortic valvuloplasty (BAV) before transcatheter aortic valve replacement (TAVR), and to show how this technique affected TAVR prosthesis selection and procedural outcomes.

Methods And Results: One hundred and eleven patients underwent simultaneous contrast injection during valvuloplasty pre-TAVR to confirm the indication for prosthesis size provided by non-invasive imaging studies. A successful injection was achieved in 95 patients (85.

Accuracy of intracardiac echocardiography for aortic root assessment in patients undergoing transcatheter aortic valve implantation.

Background: Multislice computed tomography (MSCT) has generally been accepted as the most accurate modality fulfilling this purpose with good reproducibility. A major drawback of MSCT consists in the use of contrast dye, which may be unsafe in transcatheter aortic valve implantation (TAVI) patients who frequently are affected by renal failure. We sought to appraise the accuracy of intracardiac echocardiography (ICE) in measurements of structures in the aortic root in patients undergoing TAVI.
