BACKGROUND: The aim of this study was to compare the early outcomes of octogenarians undergoing minimally invasive right anterior mini-thoracotomy aortic valve replacement (RAT-AVR) with those undergoing transcatheter aortic valve implantation (TAVI) for aortic valve disease. METHODS: In this single-center retrospective study, data were collected from octogenarians before and after RAT-AVR and TAVI between January 2021 and July 2022. Short-term outcomes, including the length of hospital stay, in-hospital mortality, all-cause mortality, and other major postoperative complications, were compared and analyzed...

Aims: We report 30-day, 1-year, and 3-year outcomes for a new TAVR programme that used five different transcatheter heart valve (THV) systems. Methods: From 2014 to 2020, 122 consecutive patients with severe aortic stenosis (AS) received TAVR based on the Heart Team decision. Outcomes were analysed for the whole study population and in addition the first 63 patients (Cohort A, 2014 to 2019) were compared to the last 59 patients (Cohort B, 2019 to 2020). Outcomes included VARC-2 definitions and device performance assessed via transthoracic echocardiography by independent high-volume investigators...

PURPOSE: This study aims to evaluate the perioperative outcomes of aortic valve replacement (AVR) via right anterior minithoracotomy (RAT) during the learning curve. METHODS: It was a retrospective, observational, cohort study of patients who underwent RAT AVR from June 2015 to April 2022. Primary outcomes measured were 30-day morbidity and mortality. RESULTS: A total of 107 consecutive patients underwent elective RAT AVR. Our patients were mostly male (78...

In the 4-year update of the EVOLUT Low-Risk Trial (NCT02701283), the authors highlight a non-significant improvement in the primary endpoint and a statistically significant, yet clinically irrelevant, enhancement in hemodynamics with transcatheter aortic valve replacement (TAVR) compared to surgical aortic valve replacement (SAVR). Overlooking the concurrent surgical procedures in SAVR patients, mortality rates remain similar at 4 years. Unaddressed is the substantial increase in permanent pacemaker implantations with TAVR and the fate of patients with paravalvular leaks...

OBJECTIVES: While current data show a clear trend towards the use of bioprosthetic valves during aortic valve replacement (AVR), durability of bioprosthetic valves remains the most important concern. We conducted a 1st systematic review of all available evidence that analysed early and mid-term outcomes after AVR using the Inspiris RESILIA™ bioprosthesis. METHODS: A systematic literature search was performed to identify all relevant studies evaluating early and mid-term outcomes after AVR using the Inspiris RESILIA bioprosthesis and including at least 20 patients with no restriction on the publication date...

Mitral valve surgery (MVS), with repair preferred to replacement, is a common procedure for the treatment of severe primary mitral regurgitation (MR) related to leaflet prolapse. Structural complications after MVS include left ventricular outflow obstruction, paravalvular leak and atrial septal defect. Intraoperative trans-oesophageal echocardiography (TEE) and predischarge transthoracic echocardiography (TTE) specifically screen for these complications. Ventricular septal defect (VSD), a known complication after aortic valve surgery, is rarely reported after MVS...

A 68-year-old male patient was admitted for extremities edema and diagnosed with infective endocarditis (IEIE). The patient underwent mitral and aortic valve mechanical valve replacement due to rheumatic heart valve disease 26 years ago. He underwent mechanical aortic valve and bioprosthetic tricuspid valve replacement due to mechanical aortic valve dysfunction and severe tricuspid valve regurgitation 1 year ago. Two months ago, the patient underwent emergency permanent pacemaker implantation due to syncope caused by a third-degree atrioventricular block...

Aims: To report our single-center data regarding the initial 52 consecutive patients with a bicuspid aortic valve who underwent a Transcatheter Aortic Valve Implantation (TAVI) procedure using the new balloon-expandable MYVAL system. The focus is on reporting procedural details and outcomes over the 30-day postoperative period. Methods: From December 2019 to July 2023, 52 consecutive patients underwent a TAVI procedure with bicuspid anatomy. All patients had moderate to-high surgical risk or were unsuitable for surgical aortic valve replacement based on the Heart Team's decision...

AIM: Transcatheter mitral valve-in-valve (TMViV) replacement for degenerated surgically implanted bioprosthetic valves has been described by both transseptal and transapical approaches. The balloon-expandable Myval transcatheter valve (Meril Life Science, Vapi, India) is commonly used for transcatheter valve-in-valve procedures in India. This study aimed to report in-hospital, 30-day, and 1-year outcomes of Myval patients who underwent TMViV in a single tertiary care centre in India. METHODS: Symptomatic patients with surgical bioprosthetic mitral valve failure with New York Heart Association (NYHA) class III-IV symptoms, despite optimal medical therapy and high or very high risk for redo surgery, were assigned to TMViV following heart team discussions...

BACKGROUND: Transcatheter closure of transcatheter heart valve (THV)-related paravalvular leak (PVL) is associated with a high failure rate with available devices due to the complex interaction of THV and aortic/mitral annulus. OBJECTIVES: This study reports novel transcatheter techniques to treat PVL after THV. METHODS: We describe consecutive patients who underwent PVL closure after transcatheter aortic valve replacement (TAVR) or transcatheter mitral valve replacement (TMVR)...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) revolutionized the therapy of severe aortic stenosis (AS) with rising numbers. Mixed aortic valve disease (MAVD) treated by TAVR is gaining more interest, as those patients represent a more complex cohort as compared to isolated AS. However, concerning long-term outcome for this cohort only limited data is available. AIMS: To assess the prevalence of MAVD in TAVR patients, investigate its association with paravalvular regurgitation (PVR), and analyse its impact on long-term mortality after TAVR...

BACKGROUND: There are limited data on the impact of transcatheter heart valve (THV) type on the outcomes of surgical explantation after THV failure. AIMS: We sought to determine the outcomes of transcatheter aortic valve replacement (TAVR) explantation for failed balloon-expandable valves (BEV) versus self-expanding valves (SEV). METHODS: From November 2009 to February 2022, 401 patients across 42 centres in the EXPLANT-TAVR registry underwent TAVR explantation during a separate admission from the initial TAVR...

OBJECTIVE: The main purpose of this study was to evaluate and compare the in-hospital, 1-month and 1-year post-procedure outcomes of patients treated with Evolut-R 34 mm and Evolut-R 23/26/29 mm devices. Additionally, the study aimed to identify factors that could predict the occurrence of ≥ mild paravalvular leaks (PVL). METHODS: Between April 2015 and May 2022, 269 consecutive patients who underwent transcatheter aortic valve implantation (TAVI) with Evolut-R 34 mm (n = 66, 24...

BACKGROUND: Percutaneous closure of aortic and ventricular pseudoaneurysms (PSA) has only been reported on a case report and series basis. In previous case reports, percutaneous closure has been performed successfully in patients of prohibitive surgical risk. This case series aims to show feasibility of percutaneous closure of aortic and ventricular pseudoaneurysm secondary to perivalvular leak (PVL) in a small patient population and the utility of multimodality imaging as an integral tool in procedural planning...

We present 2 cases of significant mitral regurgitation secondary to pericardial patch avulsion from the anterior mitral valve leaflet after aortic valve replacement with aortic annulus enlargement. Both cases were successfully managed by transcatheter repair with off-label implantation of occluder devices.

INTRODUCTION: Indications for transcatheter aortic valve implantation (TAVI) continue to expand. Very often TAVI must be done in large annuli. Implantation of the bigger prostheses is often associated with more procedural problems, which may affect the outcomes. AIM: To compare the outcomes of TAVI procedures using the self-expandable Medtronic Evolut R 34 with the smaller Evolut R or Evolut Pro 23, 26 or 29. MATERIAL AND METHODS: We analysed 87 patients who received self-expandable Medtronic Evolut R and Pro valves...

BACKGROUND: The new balloon-expandable (BE) Myval transcatheter heart valves (THV) has shown promising early results with low paravalvular leak (PVL) and permanent pacemaker implantation (PPI) rates. Limited data are available regarding its long-term performance. We aimed to compare the 2-year clinical and echocardiographic outcomes of transcatheter aortic valve replacement (TAVR) using the self-expanding (SE) Evolut R and the BE Myval THVs. METHODS: The EVAL study included 166 patients with severe aortic valve stenosis who underwent TAVR either with SE Evolut R (n = 108) or BE Myval (n = 58) THV...
