INTRODUCTION: Rheumatic mitral stenosis (MS) is an important health issue in developing countries. Assessment of the correct mitral valve area (MVA) is essential for the timing of intervention. Most of the parameters for the assessment of rheumatic MS are derived from Two-dimensional (2D) echocardiography. Three-dimensional (3D) echocardiography is commonly used in our daily practice at the present time. The aim of this study was to assess the value of 3D echocardiography mitral valve vena contracta area (VCA) in predicting the severity of Rheumatic MS by comparing 3D planimetry...

RATIONALE: Patent ductus arteriosus (PDA) ligation by open surgery is more difficult and dangerous in elderly patients than in infants. Nowadays, simple and safe interventional catheterization technology is used for the closure of uncomplicated isolated PDAs. Therefore, an alternative less invasive therapeutic option must be developed to treat complicated PDA. PATIENT CONCERNS: A 53-year-old woman presented with gradually exacerbated dyspnea on effort and continuous cardiac murmurs...

RATIONALE: Cardiac inflammatory myofibroblastic tumor (IMT) is a rare primary cardiac tumor which is currently considered as a low-grade neoplasm. The tumor has a predilection in infants and adolescents and primarily occurs as an endocardial-based cavitary mass. However, cardiac IMT that only involves the interventricular septum in middle-aged adults is extremely rarely reported. Considering its infrequency, we report a rare clinical case, with the aim of sharing our experience during the diagnostic procedures...

BACKGROUND: Right ventricular apical (RVA) pacing is related to adverse left ventricular (LV) remodelling. This study assessed changes in global longitudinal strain (GLS) after permanent RVA pacing, and investigated whether GLS at one month can predict later LV ejection fraction (LVEF) decline. METHODS: The study enrolled 68 patients with normal LVEF (≥50%) who underwent dual chamber pacemaker implantation for third-degree atrioventricular block. Global strains and LVEF were assessed using three-dimensional (3D) speckle tracking strain echocardiography (STE)...

BACKGROUND: Spontaneous T2DM in rhesus monkeys manifests as isolated diastolic dysfunction in the early stage of diabetic cardiomyopathy, similar to humans. Myocardial deformation measurements have emerged as a superior way to measure left ventricular (LV) function in the early stage of cardiac dysfunction, making it possible to further evaluate early-stage LV dysfunction in spontaneous T2DM rhesus monkeys. METHODS: Spontaneous T2DM rhesus monkeys with isolated diastolic dysfunction (T2DM-DD, n = 10) and corresponding nondiabetic healthy animals (ND, n = 9) were prospectively scanned for a CMR study...

CLINICAL INTRODUCTION: A 57-year-old man from the USA with a history of atrial fibrillation and hypertension was evaluated for progressive dyspnoea and decreased energy. The patient denied a history of congestive heart failure, systemic symptoms or myocardial infarction. He was found to have a 3/6 holosystolic murmur radiating to the axilla. Transthoracic echocardiography (TTE) reported a reduced ejection fraction of 40%, mitral valve regurgitation and absence of interatrial shunts. The remaining cardiac valves were without abnormality...

There is a great need for training in pediatric echocardiography. In addition to physicians being trained in pediatric cardiology and echocardiography technologists, neonatologist, pediatric intensivists, and other health care professionals may be interested in such training. Since, there is limited opportunity of training on live patients, echocardiographic simulators may be of help. No simulator with complete range of echocardiographic modalities is available for neonates and infants. The aim of this project was to develop a mannequin-based echocardiographic simulator capable of simulating full range of pediatric 2D, color flow Doppler, spectral Doppler, and M-mode echocardiograms...

Ischemic mitral regurgitation (iMR) augments risk for right ventricular dysfunction (RVDYS ). Right and left ventricular (LV) function are linked via common coronary perfusion, but data is lacking regarding impact of LV ischemia and infarct transmurality-as well as altered preload and afterload-on RV performance. In this prospective multimodality imaging study, stress CMR and 3-dimensional echo (3D-echo) were performed concomitantly in patients with iMR. CMR provided a reference for RVDYS (RVEF < 50%), as well as LV function/remodeling, ischemia and infarction...

BACKGROUND: Evaluation of the tricuspid annulus is crucial for the decision making at the time of left heart surgery. Current recommendations for tricuspid valve repair are based on two-dimensional (2D) transthoracic echocardiography (TTE), despite the known underestimation compared with three-dimensional (3D) echocardiography. However, little is known about the differences in 3D tricuspid annular (TA) sizing using TTE versus transesophageal echocardiography (TEE). The aims of this study were to (1) compare 2D and 3D TA measurements performed with both TTE and TEE and (2) compare two 3D methods for TA measurements: multiplanar reconstruction (MPR) and dedicated software (DS) designed to take into account TA nonplanarity...

Dilated cardiomyopathy (DCM) is generally thought as a final common pathway of several conditions leading to the same clinical phenotype. Multiple imaging modalities play a fundamental role in recognizing the underlying pathological substrate in DCM. Areas covered: Echocardiography represents the first reliable and easily accessible diagnostic tool, allowing the identification of associated cardiac abnormalities, such as valve disease and highlighting features associated with an adverse prognosis. Recent advances in technology such as strain analysis and 3D-echocardiography have improved the diagnostic and prognostic capabilities of this technique...
