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)...

BACKGROUND: The optimal functional evaluation of coronary artery stenosis in patients with severe aortic stenosis (AS) has not been established. The objective of the study was to evaluate the instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) in patients with and without severe AS. METHODS: We retrospectively investigated 395 lesions in 293 patients with severe AS and 2257 lesions in 1882 patients without severe AS between 2010 and 2022 from a subgroup of the Interventional Cardiology Research In-Cooperation Society FFR Registry...

OBJECTIVE: To assess the intraoperative use of 3-dimensional transesophageal echocardiography (3D TEE) in cardiac surgical centers, the authors created a survey aimed at evaluating the availability of equipment and the use of 3D TEE for specific surgical and interventional procedures and single-image modalities. The respondents were asked to identify the perceived impact on patient management and current limitations to its routine use. DESIGN: A multiple choice 25-question online survey submitted to the members of the European Association of Cardiothoracic Anesthesia and Intensive Care (EACTAIC) on December 6, 2021, and closed on January 31, 2022...

BACKGROUND: Atrioventricular block (AVB) is a frequent complication in patients undergoing transcatheter aortic valve implantation (TAVI). Right apex ventricular pacing (RVP) represents the standard treatment but may induce cardiomyopathy over the long term. Left bundle branch area pacing (LBBAP) is a promising alternative, minimizing the risk of desynchrony. However, available evidence with LBBAP after TAVI is still low. OBJECTIVE: To assess the feasibility and safety of LBBAP for AVB post-TAVI compared with RVP...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) serves a growing range of patients with severe aortic stenosis (AS). TAVI has evolved to a streamlined procedure minimizing length of hospital stay. AIMS: To evaluate the safety and efficacy of an early discharge (ED) strategy after TAVI. METHODS: We performed an international, multi-center, prospective observational single-arm study in AS patients undergoing TAVI with the ACURATE valve platform...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become a viable alternative to palliation in patients with severe aortic stenosis. We compared general anesthesia to conscious sedation for TAVI procedures with respect to post operative morbidity, hospital length of stay, and financial burden. METHODS: We conducted a retrospective review of prospectively collected data in patients undergoing transfemoral TAVI procedures from 2012 to 2017. Patients were matched based on age and sex and classed into either general anesthesia or conscious sedation groups respectively...

INTRODUCTION: Aortic stenosis is the most common primary valve disease and requires invasive treatment. Transcatheter aortic valve implantation (TAVI) from a transfemoral access is a routine intervention worldwide. AIM: To investigate the correlation between external iliac artery diameter (EIAD) indexed to body surface area (BSA) (EIAD-BSA) and access site complications in patients undergoing TAVI via transfemoral access (TF) (TF-TAVI). MATERIAL AND METHODS: Patients underwent TF-TAVI in 2017-2019 at the Upper-Silesian Medical Center in Katowice...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has become widely used in recent years, However, there is also an increasing need for removal of TAVR valves due to prosthetic valve dysfunction (PVD) and the development of infective endocarditis. Surgical aortic valve replacement (AVR) for these patients is risky due to the original patient background and anatomic conditions. Intuity rapid deployment aortic valve (Edwards Lifesciences, Irvine, CA) replacement would be useful for such high risk patients to prevent longer cardiac arrest time and obtain good hemodynamic results...

Patients with severe aortic stenosis (AoS) often present with acute heart failure and compensation, frequently leading to cardiogenic shock. Transcatheter Aortic Valve Replacement (TAVR) has been recently performed as a bailout treatment in such patients. The aim of our meta-analysis is to compare urgent TAVR with elective procedures. We systematically screened three databases searching for studies comparing urgent vs elective TAVR. Primary endpoint is the 30-days mortality. Secondary endpoints included in-hospital mortality, device success, periprocedural vascular complications, 30-days stroke, 30-days acute kidney injury (AKI), permanent pacemaker implantation (PPM), moderate or severe paravalvular leakage, and 30-days bleeding...

Background: Echocardiography has long been established as the primary noninvasive method for diagnosing pulmonary hypertension (PH) prior to transcatheter aortic valve replacement (TAVR) in patients with severe aortic valve stenosis (AS). In recent years, radiological methods for diagnosing PH have been investigated. Measurements such as the computed tomography angiography (CTA)-derived pulmonary artery (PA) diameter and PA diameter/body surface area (PA/BSA) have shown promising results regarding their diagnostic strength...

We report a case of simultaneous transcatheter aortic valve replacement and endovascular aneurysm repair. Our aim was to advocate the role of local and regional anesthesia as a key contributor in maintaining hemodynamic stability and avoiding abrupt blood pressure change. Endovascular combined procedures are gaining popularity for their numerous advantages. Nevertheless, they carry significant risks for their hemodynamic implications. It is imperative to acknowledge the modifications occurring after each correction and act accordingly...

AIMS: A considerable proportion of candidates for transcatheter aortic valve implantation (TAVI) have underlying heart failure (HF) with preserved ejection fraction (HFpEF), which can be challenging for diagnosis because significant valvular heart disease should be excluded before diagnosing HFpEF. This study investigated the long-term prognostic value of the pre-procedural H2 FPEF score in patients with preserved ejection fraction (EF) undergoing TAVI. METHODS AND RESULTS: Patients who underwent TAVI between October 2013 and May 2017 were enrolled from the Optimized CathEter vAlvular iNtervention-Transcatheter Aortic Valve Implantation Japanese multicentre registry...

BACKGROUND: The impact of new-onset left bundle branch block (N-LBBB) developing after Transcatheter Aortic Valve Replacement (TAVR) on cardiac function and mechanical dyssynchrony is not well defined. METHODS: We retrospectively screened all patients who underwent TAVR in our centre between Oct 2018 and Sept 2021 (n = 409). We identified 38 patients with N-LBBB post-operatively (of which 28 were persistent and 10 were transient), and 17 patients with chronic pre-existent LBBB (C-LBBB)...

The advent of transcatheter aortic valve implantation (TAVI) has caused a paradigm shift in the management of aortic stenosis away from traditional surgical aortic valve replacement (SAVR). However, uncertainty remains about the long-term (>10 year) durability of TAVI valves, especially in younger patients. This viewpoint collates life expectancy data from Australia and Aotearoa New Zealand to propose sex-specific age-based recommendations for choice of SAVR versus TAVI in their respective general populations and among Aboriginal and Torres Strait Islander people in Australia and both Māori and Pacific peoples living in Aotearoa New Zealand...

When neither surgical valve replacement nor transcatheter aortic valve implantation is possible, performing an apico-aortic conduit remains a therapeutic option. This procedure has become rare and the rigid angled apical connectors usually used to facilitate ventricular anastomosis are no longer commercially available. We described the technique that we performed on a 60-year-old patient with readily available material.

Novel dedicated devices allow transcatheter treatment of pure aortic regurgitation (AR). The JenaValve Trilogy Heart Valve System was introduced as the first dedicated and on-label AR transcatheter aortic valve replacement system, implementing a locator-based and calcium-independent anchoring mechanism. Here, we present the first-in-human transcatheter aortic valve replacement for pure AR via a transcaval access in a patient with prohibitive alternative arterial accesses.

BACKGROUND: The transcarotid (TC) vascular access for transcatheter aortic valve implantation (TAVI) has emerged as the first-choice alternative to the transfemoral access, in patients unsuitable for the latter. The use of both the left and right common carotid arteries (CCAs) for TC-TAVI has been described, but the optimal side is subject to debate. We conducted this pilot study to compare the level of vessel tortuosity and plaque burden from either the left CCA to the aortic annulus, or the right CCA to the aortic annulus, considering them as surrogates for technical and procedural complexity...
