Background: Right ventricular outflow tract obstruction (RVOTO) is a cause of hemodynamic instability that can occur in several situations, including cardiac surgery, lung transplantation, and thoracic surgery, and in critically ill patients. The timely diagnosis of RVOTO is important because it requires specific considerations, including the adverse effects of positive inotropes, and depending on the etiology, the requirement for urgent surgical intervention.

Methods: The objective of this systematic review and meta-analysis was to determine the prevalence of RVOTO in adult patients, and the distribution of all reported cases by etiology.

Impact of availability of catheter laboratory facilities on management and outcomes of acute myocardial infarction presenting with out of hospital cardiac arrest.

Resuscitation

January 2022

Keele Cardiovascular Research Group, School of Medicine, Keele University, Stoke-on-Trent, United Kingdom; Department of Cardiology, Royal Stoke University Hospital, Stoke-on-Trent, United Kingdom; Department of Medicine, Thomas Jefferson University, Philadelphia, PA, USA. Electronic address:

Objectives: We aimed to identify whether the availability of catheter laboratory affects clinical outcomes of out-of-hospital cardiac arrest (OHCA) complicating myocardial infarction (AMI).

Methods: Patients admitted with a diagnosis of AMI and OHCA from the Myocardial Ischaemia National Audit Project (MINAP) between 2010 to 2017 were stratified into three groups based on initial hospital's catheter laboratory status: hospitals without a catheter laboratory (No-catheter lab hospitals), hospitals with diagnostic catheter laboratory (Diagnostic hospitals), and hospitals with PCI facilities (PCI hospitals). We used multivariable logistic regression to evaluate factors associated with clinical outcomes.

Infective Endocarditis Caused by Staphylococcus aureus After Transcatheter Aortic Valve Replacement.

Can J Cardiol

January 2022

Québec Heart & Lung Institute, Laval University, Québec City, Québec, Canada; Hospital Clinic, Barcelona, Spain. Electronic address:

Background: Staphylococcus aureus (SA) has been extensively studied as causative microorganism of surgical prosthetic-valve infective endocarditis (IE). However, scarce evidence exists on SA IE after transcatheter aortic valve replacement (TAVR).

Methods: Data were obtained from the Infectious Endocarditis After TAVR International Registry, including patients with definite IE after TAVR from 59 centres in 11 countries.

The use of bioprosthetic valves for treating patients with severe valve disease has increased over the last 2 decades, and, as a consequence, a growing number of patients with failing surgical bioprosthesis is expected in the near future. In this setting, valve-in-valve (ViV) transcatheter aortic/mitral valve replacement (TAVR and TMVR) has emerged as an alternative to redo surgery. Despite the increasing experience in ViV procedures, the development of these techniques faces several specific challenges, mainly related to the unique anatomical and physiological characteristics of ViV-TAVR/TMVR.

Background: Sutureless-surgical aortic valve replacement (SU-SAVR) has been proposed as a surgical alternative for treating aortic stenosis, which facilitates a minimally invasive approach. While some studies have compared the early outcomes of SU-SAVR versus transcatheter aortic valve replacement (TAVR), most data were obtained in high-risk patients and/or limited to in-hospital outcomes. This study aimed to compare in-hospital and midterm clinical outcomes following SU-SAVR and TAVR in low-risk patients with aortic stenosis.

5-Year Outcomes Comparing Surgical Versus Transcatheter Aortic Valve Replacement in Patients With Chronic Kidney Disease.

JACC Cardiovasc Interv

September 2021

Institut Universitaire de Cardiologie et de Pneumologie de Québec/Québec Heart & Lung Institute, Laval University, Québec, Québec, Canada.

Objectives: The aim of this study was to compare 5-year cardiovascular, renal, and bioprosthetic valve durability outcomes in patients with severe aortic stenosis (AS) and chronic kidney disease (CKD) undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR).

Background: Patients with severe AS and CKD undergoing TAVR or SAVR are a challenging, understudied clinical subset.

Methods: Intermediate-risk patients with moderate to severe CKD (estimated glomerular filtration rate <60 mL/min/m) from the PARTNER (Placement of Aortic Transcatheter Valve) 2A trial (patients randomly assigned to SAPIEN XT TAVR or SAVR) and SAPIEN 3 Intermediate Risk Registry were pooled.

Background: The aim of this randomized study was to compare the success and complication rates of different access sites for the treatment of superficial artery stenosis.

Methods And Results: A total of 180 consecutive patients were randomized in a prospective study to treat symptomatic superficial femoral artery stenosis via radial (RA), femoral (FA), or pedal artery (PA) access. Technical success was achieved in 96.

Background: Mechanisms underlying the obesity-breast cancer link involve inflammation but need to be elucidated. Determining obesity by combining body mass index (BMI) with the waist circumference (WC) may clarify the role of inflammatory and hormonally related markers in breast cancer. We examined the effect of combining adiposity indices (BMI/WC) with the gene expression of several biomarkers involved in breast cancer.

Background: Radiation therapy is among the most effective and commonly used therapeutic modalities of cancer treatments in current clinical practice. The fundamental paradigm that has guided radiotherapeutic regimens are 'one-size-fits-all', which are not in line with the dogma of precision medicine. While there were efforts to build radioresponse signatures using OMICS data, their ability to accurately predict in patients is still limited.

Introduction: Transcatheter aortic valve replacement (TAVR) has become a treatment of reference for patients with symptomatic severe aortic stenosis, and the balloon-expandable SAPIEN 3 and SAPIEN 3 Ultra transcatheter heart valve systems are two of the most broadly used worldwide. Lately, TAVR has progressively expanded toward the treatment of low-risk patients.

Areas Covered: In this review we aimed to describe the main characteristics of the SAPIEN 3 valve, and to delineate the main clinical findings regarding the safety and efficacy associated with this THV system in low-risk patients undergoing TAVR.

This International Consensus Classification and Nomenclature for the congenital bicuspid aortic valve condition recognizes 3 types of bicuspid valves: 1.

Article Synopsis
  • - There are three types of congenital bicuspid aortic valves identified: Fused type (with three subtypes), 2-sinus type (with two subtypes), and Partial-fusion type.
  • - The Fused type includes specific cusp fusion patterns, while the 2-sinus type is categorized by the orientation of the sinuses.
  • - Additionally, three types of bicuspid aortopathy are recognized: Ascending phenotype, root phenotype, and extended phenotypes.

Heart failure following transcatheter aortic valve replacement.

Expert Rev Cardiovasc Ther

August 2021

Department of Cardiology, Quebec Heart & Lung Institute, Laval University, Quebec City, Quebec, Canada.

: Over the past decade, the number of transcatheter aortic valve replacement (TAVR) procedures has increased exponentially. Despite major improvements in both device and successes, the rate of hospital readmission after TAVR remains high, with heart failure (HF) decompensation being one of the most important causes.: This review provides an overview of the current status of HF following TAVR, including details about its incidence, clinical impact, contributing factors, and current and future treatment perspectives.

Mitral regurgitation (MR) is the most prevalent valvular heart disease and, when left untreated, it confers a poorer prognosis. Catheter-based repair therapies face some limitations like their applicability on challenging anatomies and the potential recurrence of significant MR over time. Transcatheter mitral valve replacement (TMVR) has emerged as a less invasive approach potentially overcoming some of the current limitations associated with transcatheter mitral valve repair.

Background: Left atrial appendage closure is an established therapy in patients with atrial fibrillation. Although device-related thrombosis (DRT) is relatively rare, it is potentially linked to adverse events. As data on DRT characteristics, outcome, and treatment regimen are scarce, we aimed to assess these questions in a multicenter approach.
