BACKGROUND: The aim of our study was to compare the effect of interventricular (VV) delay optimisation in CRT recipients based on systolic dyssynchrony index (SDI) derived from the three-dimensional echocardiography (3DE) versus QRS width assessment, on left ventricle volume reduction at the 12-month follow-up. METHODS: We included 63 patients with recently implanted CRT in this randomized, open-label trial. Patients were randomized to VV delay optimisation based on QRS complex width measurement in the group 1 (n=31) to obtain the narrowest QRS complex and based on SDI in group 2 (n=32) to achieve its lowest possible value...

Background: Arterial stiffness increases pressure load to the left ventricle (LV), leading to LV hypertrophy and subendocardial ischemia. Neurohormones stimulate myocardial fibrosis and LV dysfunction. We aimed to explore the associations of arterial stiffness and plasma aldosterone with multi-directional, layer-specific LV, and left atrial (LA) mechanical function in hypertensive patients. Methods: Layer-specific LV global longitudinal strain (GLS-trans, GLS-endo, GLS-epi), global circumferential strain (GCS-trans, GCS-endo, GCS-epi), LV torsional parameters, and LA global longitudinal strain (LA GLS) were analyzed by two-dimensional speckle tracking echocardiography in 195 hypertensive patients (110 men, mean age 55 years)...

Atrial septal aneurysm (ASA) is a localized deformity of the interatrial septum, which protrudes into the right and/or left atrium. ASA with defects is a source of cardiac embolism. Although transcatheter closure is now a common procedure, it is still challenging in patients with complicated ASA. We describe a case of giant atypical multiperforated ASA with irregular mobility, which showed a rare "aneurysm in aneurysm" structure. Real-time three-dimensional transesophageal echocardiography showed vivid images, which clearly demonstrated these irregular shaped defects mimicking the atriotomy view, and played a crucial role in guiding the transcatheter closure...

BACKGROUND: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) has been proved to effectively rescue patients from refractory cardiogenic shock. The role of the right ventricle in VA-ECMO has been emphasized, but quantitative right ventricular (RV) analysis in this population has been lacking. Three-dimensional echocardiography (3DE) is currently suggested for RV volumetric analysis. The aims of this study were to assess 3DE-derived RV ejection fraction (RVEF) in patients with refractory cardiogenic shock stabilized by VA-ECMO and to explore the association between 3DE-derived RVEF and weaning success as well as the prognosis after the first intent of decannulation...

Anterior mitral valve leaflet (AMVL) perforation is most commonly seen in the setting of infective endocarditis. We present a case of AMVL perforation in a previously healthy 62-year-old male who presented with a six-month history of worsening dyspnea and peripheral edema. Blood cultures, inflammatory markers, and autoimmune profile were negative. Transthoracic echocardiography demonstrated severe mitral regurgitation (MR) with a possible AMVL perforation, which was confirmed by three-dimensional transesophageal echocardiography as a well-circumscribed hole in the A2 segment...

Real time three dimensional transesophageal echocardiography (3D TEE) is probably the most powerful and convincing imaging method for understanding the complicated multiform morphology and for evaluating geometry, dynamics and function of degenerative and functional mitral valve (MV) regurgitation. Moreover, color Doppler 3D TEE has been valuable to identify the location of the regurgitant orifice and the severity of the mitral regurgitation. 3D TEE has been shown to be of enormous value in helping surgeons to perform MV repair...
