BACKGROUND: To investigate the left atrial (LA) size as an independent predictor of mortality following coronary artery bypass surgery (CABG). METHODS: This single center study evaluated determinants of mortality in 1070 patients who underwent isolated CABG from 2005-2014. Clinical, laboratory and demographic data were obtained from medical records. Collinearity between enlarged LA size (diameter ≥ 4 cm) and covariates was identified. The adjusted effects of enlarged LA size on 30-day mortality post CABG were tested using multiple logistic regression models...

OBJECTIVES: This is an early feasibility clinical test of mitral loop cerclage annuloplasty to treat secondary mitral valve regurgitation. BACKGROUND: Secondary mitral regurgitation is characterized by cardiomyopathy, mitral annular enlargement, and leaflet traction contributing to malcoaptation. Transcatheter mitral loop cerclage applies circumferential compression to the mitral annulus by creating a loop through the coronary sinus across the interventricular septum, protecting entrapped coronary arteries from compression, and interactive annular reduction under echocardiographic guidance...

High mitral inflow early (E) velocity to tissue Doppler E' ratio (E/E') and an E to late diastolic filling velocity ratio (E/A) are used to evaluate left ventricular (LV) diastolic function and filling pressure, but the usefulness of combined assessment of E/E' and E/A is not fully understood. Methods: We retrospectively analyzed 1,266 patients who underwent echocardiography to assess cardiac function. Patients were grouped based on the values of E/E' (low E/E'<15, high E/E'≥15) and E/A (low E/A≤0...

Redo aortic valve replacement (AVR) performed simultaneously with left ventricular assist device (LVAD) implantation carries potential for increased mortality rates. Although transcatheter AVR has been used for patients with previous LVAD placement, no literature reports concomitant valve-in-valve transcatheter AVR and LVAD implantation. Our patient had severe aortic prosthetic valve deterioration and advanced heart failure. Given the risks associated with reoperative aortic valve surgery, we chose transcatheter AVR at the time of LVAD implantation...

Heart disease is the leading cause of death in the USA, accounting for about one in every four deaths. Age is the greatest risk factor for heart disease in both people and dogs; however, heart disease is generally not considered as a major cause of morbidity or mortality in dogs. As part of the preliminary selection process for a veterinary clinical trial, 40 companion dogs with no history of cardiac pathology that were at least 6 years old and weighed at least 18 kg underwent a cardiac screening using Doppler echocardiography...

BACKGROUND: While left atrial (LA) enlargement is known as an early sign of left heart disease with prognostic implications in heart failure (HF), the importance of right atrial (RA) enlargement is less well studied, and the prognostic implications of interatrial size comparison are insufficiently understood. The aim of this study was to test the hypothesis that RA area larger than LA area in apical four-chamber view is associated with all-cause mortality in elderly patients with HF independent of left ventricular ejection fraction (LVEF)...

Diagnosis of dilation (D) cardiomyopathy (CMP) requires exclusion not only of inflammatory and genetically determined forms but also of some rare diseases. This 51 year old patient with history of moderate arterial hypertension approached a cardiologist because of new onset atrial fibrillation and dyspnea. Echocardiography detected dilation of all cardiac chambers with relatively preserved ejection fraction, causing suspicion of DCMP. Among conditions excluded were coronary atherosclerosis, congenital heart defect with left to right shunt, primary pulmonary hypertension, pulmonary embolism, hypertensive heart, tachycardia induced CMP, arrhythmogenic right ventricular dysplasia, noncompaction myocardium...
