Tricuspid Regurgitation: From Imaging to Clinical Trials to Resolving the Unmet Need for Treatment.

Tricuspid regurgitation (TR) is a highly prevalent and heterogeneous valvular disease, independently associated with excess mortality and high morbidity in all clinical contexts. TR is profoundly undertreated by surgery and is often discovered late in patients presenting with right-sided heart failure. To address the issue of undertreatment and poor clinical outcomes without intervention, numerous structural tricuspid interventional devices have been and are in development, a challenging process due to the unique anatomic and physiological characteristics of the tricuspid valve, and warranting well-designed clinical trials.

Echocardiographic assessment and clinical implication of functional tricuspid regurgitation in heart failure with reduced or preserved ejection fraction (ECLIPSE-HF) : Rationale and design of the study.

Purpose: Functional tricuspid regurgitation (FTR) has been shown to be associated with increased morbidity and mortality in several clinical conditions, including heart failure (HF) with reduced left ventricular ejection fraction as well as pulmonary arterial hypertension (PAH). We have designed a study aiming at: characterizing the echocardiographic morphology of the tricuspid valve apparatus and the pathophysiology of FTR in heart failure with reduced, mid-range or preserved left ventricular ejection fraction (HFrEF, HFmrEF, HFpEF) and in PAH patients; correlating the morphologic characteristics of tricuspid valve apparatus with hemodynamic severity of FTR; correlating the severity of FTR with the clinical condition and outcome.

Methods: The study will be a non-interventional, prospective, international, multicenter, longitudinal study (ClinicalTrials.

Advances in Multimodality Imaging in Cardio-Oncology: JACC State-of-the-Art Review.

The population of patients with cancer is rapidly expanding, and the diagnosis and monitoring of cardiovascular complications greatly rely on imaging. Numerous advances in the field of cardio-oncology and imaging have occurred in recent years. This review presents updated and practical approaches for multimodality cardiovascular imaging in the cardio-oncology patient and provides recommendations for imaging to detect the myriad of adverse cardiovascular effects associated with antineoplastic therapy, such as cardiomyopathy, atherosclerosis, vascular toxicity, myocarditis, valve disease, and cardiac masses.

Right Heart Chambers Longitudinal Strain Provides Enhanced Diagnosis and Categorization in Patients With Pulmonary Hypertension.

Background: Increased systolic pulmonary arterial pressure (sPAP) could lead to the mechanical dysfunction and myocardial fibrosis of the right heart chambers. Echocardiographic strain analysis has not been adequately studied in patients with pulmonary hypertension (PH).

Study Design And Methods: A cross-sectional cohort of patients with suspected PH and echocardiographic strain evaluation was recruited.

Right Heart Pulmonary Circulation Unit Response to Exercise in Patients with Controlled Systemic Arterial Hypertension: Insights from the RIGHT Heart International NETwork (RIGHT-NET).

Background: Systemic arterial hypertension (HTN) is the main risk factor for the development of heart failure with preserved ejection fraction (HFpEF). The aim of the study was was to assess the trends in PASP, E/E' and TAPSE during exercise Doppler echocardiography (EDE) in hypertensive (HTN) patients vs. healthy subjects stratified by age.

Prognostic Value of Handgrip Strength in Older Adults Undergoing Cardiac Surgery.

Background: Although multidimensional frailty scales have been proven to predict mortality and morbidity in cardiac surgery, there is a need for rapid tools that could be easily administered at the point of care. Handgrip strength (HGS) is an attractive option that can be measured in acutely ill and bed-bound patients, although it has yet to be validated in a large cardiac surgery cohort.

Methods: This is a post hoc analysis of a multicentre prospective study in older patients undergoing coronary artery bypass grafting and/or valve surgery from 2011 to 2019.

The Essential Frailty Toolset in Older Adults Undergoing Coronary Artery Bypass Surgery.

Background The Essential Frailty Toolset (EFT) was shown to be easy to use and predictive of adverse events in patients undergoing aortic valve replacement procedures. The objective of this study was to evaluate the EFT in patients undergoing coronary artery bypass grafting procedures. Methods and Results The McGill Frailty Registry prospectively included patients ≥60 years of age undergoing urgent or elective isolated coronary artery bypass grafting between 2011 and 2018 at 2 hospitals.

The role of echocardiography in amniotic fluid embolism: a case series and review of the literature.

Purpose: Amniotic fluid embolism (AFE) is a rare, but often fatal condition characterized by sudden hemodynamic instability and coagulopathy occurring during labour or in the early postpartum period. As the mechanisms leading to shock and the cardiovascular effects of AFE are incompletely understood, the purpose of this case series is to describe how AFE presents on echocardiography and review limited reports in the literature.

Clinical Features: We describe three cases of AFE at the Jewish General Hospital, a tertiary care centre in Montreal, Canada.

Age-changes in right ventricular function-pulmonary circulation coupling: from pediatric to adult stage in 1899 healthy subjects. The RIGHT Heart International NETwork (RIGHT-NET).

The present study analyzes age-specific changes in RV function and RV-PA coupling in a large cohort of apparently healthy subjects with a wide age-range, to identify reference values and to study the influence of clinical and echocardiographic cofactors. 1899 Consecutive healthy subjects underwent a standardized transthoracic echocardiographic examination. Tricuspid annular plane systolic excursion (TAPSE) and systolic pulmonary artery pressure (SPAP) were measured.

Sarcopenia in cardiac surgery: Dual X-ray absorptiometry study from the McGill frailty registry.

Background: To determine the prevalence and prognostic value of sarcopenia measured by dual x-ray absorptiometry (DXA) and physical performance tests in patients undergoing coronary artery bypass surgery or heart valve procedures.

Methods: Adults undergoing cardiac surgery were prospectively enrolled and completed a questionnaire, physical performance battery, and a DXA scan (GE Lunar) to measure appendicular muscle mass indexed to height (AMMI). Patients were categorized as sarcopenic based on European Working Group 2 guidelines if they had low AMMI defined as <7 kg/m for men or <5.

Feasibility of semi-recumbent bicycle exercise Doppler echocardiography for the evaluation of the right heart and pulmonary circulation unit in different clinical conditions: the RIGHT heart international NETwork (RIGHT-NET).

Exercise Doppler echocardiography (EDE) is a well-validated tool in ischemic and valvular heart diseases. However, its use in the assessment of the right heart and pulmonary circulation unit (RH-PCU) is limited. The aim of this study is to assess the semi-recumbent bicycle EDE feasibility for the evaluation of RH-PCU in a large multi-center population, from healthy individuals and elite athletes to patients with overt or at risk of developing pulmonary hypertension (PH).

A multicentric quality-control study of exercise Doppler echocardiography of the right heart and the pulmonary circulation. The RIGHT Heart International NETwork (RIGHT-NET).

Purpose: This study was a quality-control study of resting and exercise Doppler echocardiography (EDE) variables measured by 19 echocardiography laboratories with proven experience participating in the RIGHT Heart International NETwork.

Methods: All participating investigators reported the requested variables from ten randomly selected exercise stress tests. Intraclass correlation coefficients (ICC) were calculated to evaluate the inter-observer agreement with the core laboratory.

Muscle Mass and Direct Oral Anticoagulant Activity in Older Adults With Atrial Fibrillation.

Background: Direct oral anticoagulants (DOAC) are hydrophilic drugs with plasma levels inversely proportional to lean body mass. Sarcopenic patients with low muscle mass may be at risk for supra-therapeutic DOAC levels and bleeding complications. We therefore sought to examine the influence of lean body mass on DOAC levels in older adults with atrial fibrillation (AF).

Cardiovascular Care of the Oncology Patient During COVID-19: An Expert Consensus Document From the ACC Cardio-Oncology and Imaging Councils.

In response to the coronavirus disease 2019 (COVID-19) pandemic, the Cardio-Oncology and Imaging Councils of the American College of Cardiology offers recommendations to clinicians regarding the cardiovascular care of cardio-oncology patients in this expert consensus statement. Cardio-oncology patients-individuals with an active or prior cancer history and with or at risk of cardiovascular disease-are a rapidly growing population who are at increased risk of infection, and experiencing severe and/or lethal complications by COVID-19. Recommendations for optimizing screening and monitoring visits to detect cardiac dysfunction are discussed.

Optimal Echocardiographic Approach to the Evaluation of Tricuspid Regurgitation.

Purpose Of Review: To summarize the most recent literature on the optimal echocardiographic approach to the evaluation of tricuspid regurgitation (TR).

Recent Findings: Severe TR is increasingly recognized as an independent adverse prognostic marker. TR severity grading has been mainly based on qualitative and semiquantitative parameters according to the 2017 ASE guidelines, but new data emerging from 3D echocardiography and MRI will likely provide insights into more quantitative measurements of TR severity.

Multimodality Imaging in Evaluation of Cardiovascular Complications in Patients With COVID-19: JACC Scientific Expert Panel.

Standard evaluation and management of the patient with suspected or proven cardiovascular complications of coronavirus disease-2019 (COVID-19), the disease caused by severe acute respiratory syndrome related-coronavirus-2 (SARS-CoV-2), is challenging. Routine history, physical examination, laboratory testing, electrocardiography, and plain x-ray imaging may often suffice for such patients, but given overlap between COVID-19 and typical cardiovascular diagnoses such as heart failure and acute myocardial infarction, need frequently arises for advanced imaging techniques to assist in differential diagnosis and management. This document provides guidance in several common scenarios among patients with confirmed or suspected COVID-19 infection and possible cardiovascular involvement, including chest discomfort with electrocardiographic changes, acute hemodynamic instability, newly recognized left ventricular dysfunction, as well as imaging during the subacute/chronic phase of COVID-19.

Canadian Cardiovascular Society/Canadian Thoracic Society Position Statement on Pulmonary Hypertension.

The landscape of pulmonary hypertension (PH) has changed significantly since the last Canadian Cardiovascular Society/Canadian Thoracic Society position statement in 2005. Since then, advances in our understanding of the pathophysiology of PH and improvements in diagnostic and therapeutic options have transformed the care of patients with PH. Globally, PH has an estimated prevalence of 1%, increasing to 10% in those aged 65 years and older, most commonly due to left heart or lung disease.
