A Case of Transient Mitral Regurgitation: Not Everything Is Always What It Seems.

Mitral regurgitation (MR) is a common form of valvular heart disease that is associated with significant morbidity and mortality. MR can be broadly classified into 2 different categories: primary and secondary MR. Primary MR usually is caused by leaflet abnormalities, whereas secondary MR is a chronic disease secondary to geometric distortion of both the annulus and subvalvular apparatus because of left ventricular remodeling.

Infected thrombus in a Fontan circulation.

The Fontan operation was introduced in 1968 as a palliative treatment for patients with univentricular heart physiology. Natural history and outcomes are poor. By 10 years after Fontan operation, most patients will develop any complication such as tachyarrhythmias, any spectrum of Fontan-associated liver disease, protein-losing enteropathy, heart failure, thrombosis, and infective endocarditis among others.

Echocardiographic diagnosis and follow-up for ALCAPA syndrome treated with the Takeuchi procedure.

We present the case of an 18-year-old man with aborted sudden cardiac death. His initial echocardiogram suggested an anomalous origin of the left coronary artery from the pulmonary artery. Diagnosis was confirmed with coronary angiography.

Clinical Spectrum and Long-term Outcome of 183 Cases of Ebstein's Anomaly, Experience of Mexican Population.

Background: Ebstein's anomaly (EA) is a myopathy of the right ventricle that causes a variable spectrum of tricuspid valve delamination failure with diverse clinical and anatomical presentation. We reviewed our data of EA to establish an association between clinical and echocardiographic findings with mortality.

Methods: We divided patients in infants, Children/adolescents (Ch/A), and adults, according to age of presentation.

Right ventricular free wall strain predicts functional capacity in patients with repaired Tetralogy of Fallot.

To investigate the role of right ventricular free wall strain (RVFWSL) to predict low functional capacity in repaired tetralogy of Fallot (rTOF). We prospectively enrolled 33 patients with rTOF with moderate to severe PR who underwent rest and peak exercise echocardiography on a semisupine cycloergometer. Conventional function and strain imaging parameters of both ventricles were measured.

Clinical and echocardiographic factors associated with mitral plasticity in patients with chronic inferior myocardial infarction.

Aims: Ischaemic mitral regurgitation (IMR) is consequence of left ventricular (LV) remodelling after myocardial infarction. In some cases, the mitral valve enlarges to compensate for LV remodelling and tenting, improving its coaptation; a process termed 'plasticity'. We sought to identify clinical and echocardiographic factors associated with plasticity in patients with chronic inferior myocardial infarction (CII).

Coexisting bicuspid aortic and pulmonary valves diagnosed by 3D transthoracic echocardiography.

Coexisting bicuspid aortic and pulmonary valves is an extremely rare condition, and there have been few published cases. Diagnosis of bicuspid aortic valve is straightforward with 2D echocardiography; however, analysis of the morphology of the pulmonary valve is challenging. In this study, we report on a case of a 32-year-old man with bicuspid aortic and pulmonary valves diagnosed by 2D and 3D transthoracic echocardiography.

Impact of Surgery in Ebstein's Anomaly Using Current Surgical Criteria.

Background: In Ebstein's anomaly (EA) current surgical criteria may not translate into better long-term survival. The aim of this study was therefore to determine if surgical treatment for EA increases survival, and to analyze factors associated with mortality.Methods and Results:A retrospective study was carried out involving 103 patients with surgical indication using current criteria, comparing operated (n=49; 47.

Echocardiographic and Histologic Correlations in Patients with Severe Aortic Stenosis: Influence of Overweight and Obesity.

Background: Severe aortic stenosis (AS), leads to pathological left ventricular remodeling that may worsen with concomitant overweight and obesity (OW/O).

Methods: We aimed to prospectively analyze the impact of OW/O on ventricular remodeling in severe AS, by evaluating the percentage of intraendomyocardial fibrosis (PIEF) and the percentage of infiltrating intraendocardial lipid vacuoles (PIELV) and its relationship to global longitudinal strain (GLS) in patients with OW/O.

Results: 44 patients with severe AS were included, 13 non-obese (29%) and 31 OW/O (71%), all of them with left ventricular ejection fraction ≥ 55%.
