Aims: Recent findings regarding hypertrophic cardiomyopathy (HCM) haemodynamics emphasized the relationship between symptoms, left ventricular outflow tract obstruction (LVOTO), and the preload condition as the venous return level. As various types of exercises have different effects on peripheral vascular beds, this study sought to compare upright treadmill exercise echocardiography (EE) to semi-supine bicycle EE in maximum provoked LVOTO in HCM patients. Methods and results: Semi-supine bicycle and upright treadmill EE were prospectively performed in HCM patients with New York Heart Association functional Class II...

BACKGROUND: Diastolic pressure gradient (DPG) of ≥7 mmHg has been proposed to distinguish mixed pulmonary hypertension from isolated post-capillary pulmonary hypertension in heart failure (HF). We evaluated the changes in pulmonary hemodynamics with left ventricular assist devices (LVADs) in patients with DPG of ≥7 or <7 mmHg, and effects on peak oxygen uptake (VO2) in patients with advanced HF. METHODS: Pre- and post-LVAD implant pulmonary hemodynamics (including right atrial (RA) pressures, DPG, pulmonary vascular resistance (PVR), pulmonary capacitance (PCap) and cardiac output), echocardiography, cardiopulmonary exercise test were measured in 38 consecutive patients...

Chronic thromboembolic pulmonary hypertension (CTEPH) is the only potentially curable form of pulmonary hypertension. Rapid and accurate diagnosis is pivotal for successful treatment. Clinical signs and symptoms can be nonspecific and risk factors such as history of venous thromboembolism may not always be present. Echocardiography is the recommended first diagnostic step. Cardiopulmonary exercise testing is a complementary tool that can help to identify patients with milder abnormalities and chronic thromboembolic disease, triggering the need for further investigation...

REVIEW

Mitral valve disease represented by mitral stenosis and mitral regurgitation is the second most frequent valvulopathy. Mitral stenosis leads to an increased left atrial pressure whereas mitral regurgitation leads to an increased left atrial pressure associated with a volume overload. Secondary to an upstream transmission of this overpressure, both mitral stenosis and regurgitation lead to pulmonary hypertension and right heart failure. In addition, mitral regurgitation also leads to left ventricular dilatation and dysfunction with left heart failure...

BACKGROUND: Right ventricular (RV) function has been found to be a major factor of exercise capacity in patients with heart failure. However, the role of RV function in exercise capacity in healthy subjects has not been well studied. This study aims to validate the role of RV strain derived from speckle tracking echocardiography for exercise capacity for health check-up subjects. METHODS: This study prospectively recruited subjects from a routine health examination...

Exercise is a stress to the pulmonary vasculature. With incremental exercise, the pulmonary diffusing capacity (DLCO) must increase to meet the increased oxygen demand; otherwise, a diffusion limitation may occur. The increase in DLCO with exercise is due to increased capillary blood volume (Vc) and membrane diffusing capacity (Dm). Vc and Dm increase secondary to the recruitment and distension of pulmonary capillaries, increasing the surface area for gas exchange and decreasing pulmonary vascular resistance, thereby attenuating the increase in pulmonary arterial pressure...

Sudden cardiac death (SCD) is the leading cause of death during exercise in young athletes. Preparticipation physical examinations were developed to maintain the health and safety of athletes, including the prompt identification of those at risk for SCD. The use of medical history and physical examinations, electrocardiography, and echocardiography, or some combination thereof, is the source of continued debate. This article provides an overview of the etiology of SCD and reviews literature relating to preparticipation echocardiography, with a focus on its evolution, utility, and effectiveness...

PURPOSE: To determine lifetime cost-effectiveness of diagnostic evaluation strategies for individuals with stable chest pain and suspected coronary artery disease (CAD). METHODS: Exercise treadmill testing (ETT), stress echocardiography (SE), myocardial perfusion scintigraphy (MPS), coronary computed tomographic angiography (CCTA), and invasive coronary angiography (ICA) were assessed alone, or in succession to each other. RESULTS: Initial ETT followed by imaging wherein ETT was equivocal or unable to be performed appeared more cost-effective than any strategy employing initial testing by imaging...

Evaluation of diastolic dysfunction and diagnosis of heart failure with preserved ejection fraction (HFpEF) by echocardiography are routinely performed at rest. However, many patients with modest HFpEF develop symptoms such as dyspnea only during exercise. Therefore, echocardiographic analysis at rest could be insufficient to identify these patients. Recent studies have demonstrated the utility of diastolic stress echocardiography to evaluate diastolic dysfunction during exercise. This review attempts to summarize and discuss current studies in diastolic stress echocardiography...

Pulmonary hypertension (PH) is a spectrum disorder with multiple causes of the elevation of pressure in the lungs. It often is difficult to diagnose because it mimics many commonly reported symptoms (eg, dyspnea, exercise intolerance, chest pain). Diagnosis is made via right heart catheterization; however, transthoracic echocardiography may show evidence of elevated pulmonary pressure as the first clue to the diagnosis. Diagnostic tests to consider include a liver panel, complete blood count, and thyroid function test; electrocardiogram; chest x-ray; pulmonary function testing; and possibly lung imaging via computed tomography scan or ventilation-perfusion scan...

INTRODUCTION: Creation of a fenestration during completion of a total cavopulmonary connection (TCPC) has been associated with a reduction in early mortality and morbidity. However, the long-term benefits are negated by an associated limitation in exercise tolerance and the potential risks of thrombo-embolic complications. We sought to describe the safety and efficacy of an Amplatzer Duct Occluder II (ADO II) for transcatheter fenestration closure following TCPC. MATERIAL AND METHODS: Between January 2000 and July 2014, 102 patients underwent percutaneous closure of extra-cardiac TCPC fenestrations with a range of devices...

BACKGROUND: Exercise stress echocardiography (ESE) can be used to identify left ventricular (LV) dysfunction in asymptomatic chronic MR. NT-proBNP is the best marker for monitoring LV dysfunction. OBJECTIVE: The aim of this study was to estimate the complementary prognostic value of ESE and NT-proBNP in asymptomatic degenerative MR with preserved LV ejection fraction (EF). METHODS: Symptom-limited treadmill ESE was performed in 114 asymptomatic with significant degenerative MR (ERO >20mm, RV >30ml), LV end-systolic diameter <40mm and preserved LV function (EF >60%)...

The aim of the research was to investigate diastolic left ventricle function in athletes performing exercises requiring varying power using echocardiography. We surveyed 68 athletes aged from 12 to 27 years who were involved in swimming and volleyball. Echocardiography was used to assess cardiohaemodynamic changes in athletes using a bicycle ergometer to exercise at varying intensities. Exercising at submaximal and average power produces a proportional increase in indices of diastolic function of the heart: maximum speed of early diastolic mitral inflow streams (E) to 81,9±20,0 сm/s and maximum speed of early diastolic and mitral annulus velocity (е') to 16,6±5,7 сm/s...

BACKGROUND: Doppler echocardiography is usually the first diagnostic investigation for patients suspected with pulmonary hypertension (PH), but it is often inaccurate when used alone, especially in mild PH. HYPOTHESIS: Cardiopulmonary exercise testing (CPET) may serve as a complementary tool to improve diagnostic accuracy in echocardiography-suspected "PH possible" patients. METHODS: Eighty-eight consecutive patients with suspected PH (referred to as "PH possible" hereafter) based on echocardiography were included in the study...

Importance: Sarcomere mutations and left ventricular (LV) hypertrophy (LVH) are cardinal features of hypertrophic cardiomyopathy (HCM). However, little is known about the full spectrum of phenotypic manifestations or how LVH influences disease expression. Objectives: (1) To characterize and assess phenotypic burden in sarcomere mutation carriers (genotype positive [G+]) and (2) to investigate the correlation between LV wall thickness (LVWT) and other disease features in mutation carriers...
