BACKGROUND: In patients with hypertrophic cardiomyopathy (HCM), enlargement of the left atrium (LA) is associated with increased morbidity and mortality due to risk of atrial fibrillation (AF), stroke, and heart failure. In this study, we investigated whether LA reverse remodeling occurs following septal myectomy. METHODS: Between March 2007 and July 2015, 656 patients underwent myectomy at our institution and had pre- and postoperative transthoracic echocardiographic (TTE) recording of LA volume index (LAVI)...

BACKGROUND: Atrioventricular block (AVB) is usually due to infra-nodal disease and associated with a wide QRS complex; such patients often progress to complete AV block and pacemaker dependency. Uncommonly, infra-nodal AVB can occur within the His bundle with a narrow QRS complex. OBJECTIVE: To define clinical/echocardiographic characteristics of patients with AV block within the His bundle and report on progression to pacemaker dependency. METHODS: We retrospectively identified patients with narrow QRS complexes and documented intra-His delay or block on electrophysiologic study (Group A), or with ECG documented Mobitz II AVB/paroxysmal AVB (Group B)...

BACKGROUND: Plasma Galectin-3 is a marker of myocardial inflammation and fibrosis, was associated with left ventricular (LV) reverse remodeling after conventional surgical mitral valve repair (MVR) and predicted clinical events in patients undergoing transcatheter aortic valve replacement (TAVR). We aimed to evaluate the association between pre-interventional Galectin-3 levels and (1) reverse LV remodeling and (2) major adverse cardiovascular events (MACE) in patients undergoing percutaneous MVR...

Hypoplasia of the mitral leaflets is rarely reported in adults. We reported a 45-year-old man presented to us with palpitation, dyspnea, and severe mitral regurgitation. In echocardiographic examination, an immobile hypoplastic posterior mitral leaflet (PML) was detected. A review of clinical and echocardiographic findings of all reported cases revealed that mitral regurgitation was the most common finding associated with PML hypoplasia/uni-leaflet mitral valve. PML hypoplasia is rare and often an incidental diagnosis during echocardiography, which could be relatively well tolerated since adulthood and carries a good prognosis...

Informal training in preclinical research may be a contributor to the poor reproducibility of preclinical cardiology research and low rates of translation into clinical research and practice. Mouse echocardiography is a widely used technique to assess cardiac structure and function in drug intervention studies using disease models. The inter-observer variability (IOV) of clinical echocardiographic measurements has been shown to improve with formalized training, but preclinical echocardiography lacks similarly critical standardization of training...

BACKGROUND: The true prevalence of heart failure (HF) due to wild type transthyretin amyloidosis (ATTRwt) is likely underestimated. There is a paucity of data with regard to the management of ATTRwt-related advanced HF and the natural history of extracardiac ATTRwt. METHODS: We conducted a retrospective cohort study of patients undergoing cardiac transplant (HTx) for ATTRwt at a single institution. Comprehensive clinical data, including baseline hemodynamic and echocardiographic characteristics, and posttransplant outcomes were obtained...

OBJECTIVE: Inadequate peripheral venous drainage during minimally invasive cardiac surgery (MICS) is a challenge and cannot always be solved with increased vacuum or increased centrifugal pump speed. The present study was designed to assess the benefit of virtually wall-less transfemoral venous cannulas during MICS. METHODS: Transfemoral venous cannulation with virtually wall-less cannulas (3/8″ 24F 530-630-mm ST) was performed in 10 consecutive patients (59 ± 10 years, 8 males, 2 females) undergoing MICS for mitral (6), aortic (3), and other (4) procedures (combinations possible)...

Cardiac involvement is well characterized in sickle cell anaemia (SCA) but cardiac features associated with Haemoglobin SC (HbSC) disease are mostly unknown. We compared 60 patients with HbSC disease (median age 31 years, 25 men) to 60 SCA patients and 60 controls matched for age and gender. Left ventricular ejection fraction (LVEF), left ventricle (LV) mass index (LVMi), cardiac index and peak tricuspid regurgitation velocity (TRV) were measured using echocardiography. LV filling pressures were assessed using the ratio of early diastolic transmitral velocity to tissue velocity (E/e' ratio)...

Secondary mitral regurgitation (MR) results from left ventricular dilatation and dysfunction. Quantification of secondary MR is challenging because of the underlying myocardial disease. Clinical and echocardiographic evaluation requires a multi-parametric approach. Severe secondary MR occurs in up to one-fourth of patients with heart failure with reduced ejection fraction, which is associated with a mortality rate of 40% to 50% in 3 years. Percutaneous edge-to-edge mitral valve repair (MitraClip) has emerged as an alternative to surgical valve repair to improve symptoms, functional capacity, heart failure hospitalizations, and cardiac haemodynamics...

The right atrium (RA) is the most under-evaluated heart chamber in the clinical practice. Three-dimensional (3D) speckle-tracking echocardiography (STE) merges the benefits of 3D echocardiography and STE: volumetric and strain assessment of the RA can be performed at the same time from the same digitally acquired 3D echocardiographic dataset with a special equipment using a virtual 3D model of the RA. A diagnostic focused study is under way at the Second Department of Medicine and Cardiology Center, University of Szeged, Hungary to assess 3D-STE-derived RA variables in different patient populations, which serves as a substudy of Motion Analysis of the heart and Great vessels bY three-dimensionAl speckle-tRacking echocardiography in Pathological cases (MAGYAR-Path) Study...

Cirrhotic cardiomyopathy in end stage liver disease is currently characterized by blunted contractile systolic response to stress with or without diastolic dysfunction in the absence of known heart disease. Since the establishment of the diagnostic criteria of cirrhotic cardiomyopathy in 2005, there have been multiple studies regarding its pathophysiology and pre-transplant clinical course. The data regarding the post-transplant course of this entity are sparse. This review addresses the course and prognosis of the elements of cirrhotic cardiomyopathy after liver transplantation...

BACKGROUND: Atrial fibrillation (AF) is highly prevalent and antiarrhythmic therapy is often used to help with rhythm control. Some common echocardiographic parameters may be useful in predicting AF recurrence among these patients. OBJECTIVES: The purpose of this study was to evaluate the association between three common echocardiographic parameters [left atrial (LA) size, left ventricular ejection fraction (LVEF), and mitral regurgitation (MR)] and AF recurrence among patients treated with anti-arrhythmic medications...

In the neonatal and pediatric intensive care setting, bedside cardiac ultrasound is often used to assess ventricular dimensions and function. Depending upon the underlying disease process, it is necessary to be able to evaluate the systolic and diastolic function of left and or right ventricles. The systolic function of left ventricle is mostly assessed qualitatively on visual inspection "eye-balling" and quantitatively by measuring circumferential fraction shortening or calculating the ejection fraction by Simpson's planimetry...

Highly resolved three-dimensional (3D) fluid structure interaction (FSI) simulation using patient-specific echocardiographic data can be a powerful tool for accurately and thoroughly elucidating the biomechanics of mitral valve (MV) function and left ventricular (LV) fluid dynamics. We developed and validated a strongly coupled FSI algorithm to fully characterize the LV flow field during diastolic MV opening under physiologic conditions. Our model revealed that distinct MV deformation and LV flow patterns developed during different diastolic stages...

BACKGROUND: Acute decompensated heart failure (ADHF) is often accompanied by liver congestion through increased right atrial pressure (RAP). Liver stiffness (LS) assessed non-invasively using transient elastography is related to increased RAP and liver congestion in patients with general HF. We investigated the relationship of LS with clinical and echocardiographic variables and outcomes in patients with ADHF.Methods and Results:The subjects were 105 patients with ADHF admitted to hospital between October 2016 and June 2017...
