An Experimental Model of Myocardial Infarction for Studying Cardiac Repair and Remodeling in Knockout Mice

Cardiovascular disease is the most prevalent cause of death in Western countries, with acute myocardial infarction (MI) being the most prevalent form. ...

Surgical rescue of embolized amplatzer septal occluder.

Percutaneous transcatheter aortic valve replacement (TAVR) has become an alternative to surgical therapy for patients with severe aortic stenosis and high operative risk, but it is associated with specific complications. We report the case of a 72-year-old man who underwent the procedure without complications; however, 45 days after the procedure, he was admitted to the hospital with symptoms of heart failure secondary to severe mitral regurgitation. Necropsy findings showed prosthesis malposition and perforation of the anterior mitral leaflet caused by the contact of the stent of the CoreValve prosthesis (Medtronic, Minneapolis, MN). We discuss TAVR complications, specifically regarding low positioning of the prosthetic valve.

Primary benign myopericytoma of the left atrium.

We report the case of a rare congenital anomaly, a double-orifice mitral valve, in a 21-year-old woman who was asymptomatic and had no history of heart disease. Transthoracic echocardiography revealed two functionally normal orifices mitral valve of equal size. As the presentation in adulthood is rare, echocardiographers should be trained to make the appropriate diagnosis.

Transesophageal Doppler echocardiography has shown that significant stenosis can be detected based on the presence of aliasing with color Doppler in the stenotic area. The study aimed to assess the detection of angiographically significant coronary stenosis (ASCS) by analyzing the characteristics and velocities of resting coronary artery flow (RCF) using transthoracic coronary Doppler echocardiography (TCDE).

Atypical localization of a papillary fibroelastoma in the ligament of Marshall.

Cardiac myxomas are the most frequent cardiac tumors. Although histologically benign, in some cases myxomas may be lethal, due to impairment of cardiac dynamics and their thromboembolic potential. The study aimed to assess the clinical presentation of cardiac myxomas and their correlation with echocardiographic features and to describe the perioperative results and long-term outcome of surgically treated patients.

Twenty Years of Clinical Experience with Cardiac Myxomas: Diagnosis, Treatment, and Follow Up.

Right ventricular (RV) systolic dysfunction is a strong predictor of mortality in pulmonary hypertension (PH). The goal of this study was to investigate whether right atrium (RA) and RV myocardial strain related to PH using speckle tracking echocardiography provide a superior estimation of RV systolic function than 2-dimensional (2D)-echo.

Cardiac neoplasms are rare entities in the clinical practice. Cardiac metastatic involvement is 20 to 40 times more frequent than the primary form, representing 95% of all cardiac tumors; however, they are frequently underdiagnosed because of their clinical and oncologic features. In this report, we present two cases of cardiac metastasis from primary anaplastic thyroid carcinoma: a 69-years-old woman with right ventricular metastasis and a 61-years-old man with right atrial metastasis. Both patients died during their hospitalization and one of them underwent an autopsy.

Right ventricular longitudinal strain (RVLS) is frequently used as a measure of right ventricular systolic function. Abnormal RV strain is associated with poor prognosis in patients with pulmonary hypertension (PH); however, the measure is not always easy to obtain in patients with poor apical acoustic windows.
