Right ventricular mechanical pattern in patients undergoing mitral valve surgery: a predictor of post ‐operative dysfunction?

AbstractAimsThe PREPARE ‐MVR study (PRediction of Early PostoperAtive Right vEntricular failure in Mitral Valve repair (MVR) and to explore the associations between/Repair patients) sought to investigate the alterations of right ventricular (RV) contraction pattern in patients undergoing mitral valve replacement/repair ( MVR) and to explore the associations between pre‐operative RV mechanics and early post‐operative RV dysfunction (RVD).Methods and resultsWe prospectively enrolled 42 patients (63  ± 11 years, 69% men) undergoing open‐heart MVR. Transthoracic three‐dimensional (3D) echocardiography was performed pre‐operatively, at intensive care unit discharge, and 6 months after surgery. The 3D model of the RV was reconstructed, and RV ejection fraction (RVEF) was calculated. We decomposed the motion of the ventricle to compute longitudinal ejection fraction (LEF) and radial ejection fraction (REF). Pulmonary artery catheterization was performed to monitor RV stroke work index (RVSWi). RVEF was slightly decreased after MVR [52 (50–55) vs. 51 (46–54)%;P = 0.001], whereas RV contraction pattern changed notably. Before MVR, the longitudinal shortening was the main contributor to global systolic RV function [LEF/RVEF vs. REF/RVEF; 0.53 (0.47–0.58) vs. 0.33 (0.22–0.42);P

CONCLUSION: On the basis of a broadly based research and participatory development process, a set of indicators has been developed that enables comprehensive evaluation of the regional quality of care of cross-indication, integrated care models focusing on common diseases. In order to be able to increasingly evaluate aspects of care coordination and patient orientation, health promotion as well as nursing, palliative and emergency care in the future, it would be helpful if routine data were collected or made accessible in these areas as well.

The most common form of sustained cardiac arrhythmia, which is characterized by irregular heartbeats, is atrial fibrillation (AF). The maintenance of AF is mediated by changes in the atrial structural and electrical properties.1 AF is a major risk factor for ischemic stroke and heart failure,2,3 which are associated with enhanced morbidity, mortality, and socioeconomic burden.4 The prevalence of AF is estimated to markedly increase as the population ages. Therefore, it is important to elucidate the molecular mechanisms underlying AF.

AbstractBackgroundStereotactic minimally invasive surgery (sMIS) has been used in the treatment of intracerebral hemorrhage (ICH) in recent years and has obtained promising results. However, the outcomes of patients are associated with many factors. The aim of the present study was to retrospectively observe the relationship between hematoma shape features and the outcome of patients with spontaneous ICH following sMIS.MethodsOne hundred eighty-three patients with hypertensive ICH who underwent sMIS were enrolled. Based on hematoma shape features, the patients were assigned to a regular-shaped hematoma group (RSH group, in...

The treatment of hypertension in older adults is a major public health concern. Among the nearly 13 million persons in the United States aged 80 years or older, approximately 80% have high blood pressure (BP). Hypertension is the most potent modifiable risk factor for cardiovascular disease in older adults and has been strongly associated with stroke, myocardial infarction, heart failure, peripheral artery disease, kidney failure, and dementia. Thus, defining optimal strategies for managing elevated BP in older individuals is a high priority.

AbstractPurpose of reviewIn this review article, we aim to describe the pathophysiology of concomitant atrial fibrillation and both left and right heart failure, as well as pronounce the prognosis of having these two conditions simultaneously. This review also summarizes the current management of atrial fibrillation including stroke and thromboembolism prevention in the presence of systolic and diastolic heart failure.Recent findingsWhile rhythm control strategy is not superior to rate control strategy in atrial fibrillation patients without heart failure, catheter ablation for atrial fibrillation has shown to improve outc...

Cardiac Cancer (CC) that arises from or involves the heart can present as heart failure, chest pain, stroke or another thromboembolic event. Although patients with CC have limited treatment options, in other organ cancers such as hepatocellular carcinoma, liver transplant improves 5-year overall survival in carefully selected patients1. For CC, however, the benefit of replacing the cancerous heart is uncertain because one-year survival is generally estimated around 50% after this rare operation.
