INTRODUCTION Right ventricular apical pacing-related heart failure is reported in some patients after long-term pacing. The exact mechanism is not yet clear but may be related to left ventricular dyssynchrony induced by right ventricular apical pacing. Right ventricular septal pacing is thought to deteriorate left ventricular function less frequently because of a more normal left ventricular ac...

background: left ventricular dysfunction is one of the most powerful predictors of early and late outcomes in patients who undergo coronary artery bypass grafting (cabg). the aim of this study was to assess the early results of cabg that predict 30-day mortality and prolonged length of hospital stay (los) after cabg in patients with an ejection fraction (ef) of 30% or less. methods: seven hundr...

the optimal treatment method for right ventricular failure after valve surgery complicated by a low cardiac output has not been determined, although several case reports have been published on patients with ventricular failure and arrhythmia who were bridged to cardiac transplantation using biventricular or left ventricular assist devices. this case series illustrates successful circulatory sup...

The clinical value of cardiac color ultrasound and cardiac troponin T (cTnT) combined with dynamic electrocardiogram in evaluating the treatment effect on acute pulmonary embolism (APE) was investigated. Ninety-eight patients with APE treated in Jinan Zhangqiu District Hospital of TCM from March 2016 to February 2017 were selected, and they were examined via the cardiac color ultrasound, cTnT a...

OBJECTIVE To assess prognosis of pulmonary thromboembolism using tissue Doppler echocardiography and brain natriuretic peptide. METHODS Patients aged over 18 years were evaluated within 24 hours of confirmed diagnosis (chest tomography/pulmonary scintigraphy) of pulmonary embolism using two-dimensional echocardiography and tissue Doppler for right ventricular systolic (s') velocities, strain,...

The aetiology of right ventricular dysplasia/cardiomyopathy is presently unknown. A genetic background has been suggested, but myocarditis may play a part in its pathogenesis. Two familial cases of right ventricular dysplasia, one of whom had also a diagnosis of myocarditis, are reported. Both patients presented with ventricular arrhythmias. The father subsequently had a "flu-like" syndrome, he...
