The minimally invasive MitraClip ^™ procedure for mitral regurgitation under general anaesthesia: immediate effects on the pulmonary circulation and right ventricular function

Anaesthesia, 2014
Summary A relatively new minimally invasive cardiological procedure, called the MitraClip ™ , does not require sternotomy and may have a number of advantages compared with open mitral valve surgery, but its acute impact on the pulmonary circulation and right ventricular ...

Circulating miR-148b-3p and miR-409-3p as biomarkers for heart failure in patients with mitral regurgitation

International Journal of Cardiology, 2016
MicroRNAs (miRs) regulate gene expression in heart failure. Circulating miRs as biomarkers for heart failure in mitral regurgitation patients (MR) remain unexplored.This case-control study enrolled 32 MR patients with heart failure, 16 asymptomatic MR patients, and 12 control subjects without heart failure.

THE HEMODYNAMIC IMPACT OF MITRAL REGURGITATION, LEFT ATRIAL DYNAMICS, AND RIGHT VENTRICULAR TO PULMONARY CIRCULATION COUPLING DURING EXERCISE ON CARDIOPULMONARY EXERCISE PERFORMANCE AND CLINICAL OUTCOME IN LEFT HEART DISEASE

Journal of the American College of Cardiology, 2018
The hemodynamic impact of mitral regurgitation (MR), left atrial (LA) dynamics, and RV-to-PC coupling during exercise on cardiopulmonary function and clinical outcome has never been studied.

Floppy mitral valve/mitral valve prolapse/mitral valvular regurgitation: effects on the circulation.

Journal of cardiology, 2001
The floppy mitral valve prolapses into the left atrium in such a dynamic manner that the prolapsing floppy mitral valve becomes a space-occupying lesion within the left atrium. A significant result of the floppy mitral valve prolapsing into the left atrium during left ventricular systole is the development of a "third chamber" located between the ...

Percutaneous therapy for mitral valve regurgitation modulates level and phenotype of circulating blood cells

2017
Aim: Immune mechanisms and inflammation contribute to the pathophysiology of heart failure (HF) in different ways. As the center of immune response, dendritic cells (DCs) play an important role in LV remodeling after myocardial ischemia and myocarditis, however, the role of dendritic cells in non-ischemic HF with volume overload has not be addressed ...

Adaptations of venus peripheral circulation in mild to moderate tricuspid regurgitation

1994
The aim of the study was to assess the hypothetic relationship between right atrial mechanoreceptors stimulation due to mild to moderate tricuspid regurgitation and forearm venous tone. Method: The study group included 15 patients (9 males, 6 females, average years range 25-55) with mild to moderate tricuspid regurgitation (TR) measured by ...

Echocardiographic assessment of the right heart pulmonary circulation unit in mitral regurgitation due to mitral valve prolapse

European Heart Journal
Abstract Background Right ventricular evaluation is essential in the context of chronic mitral regurgitation (MR). Chronic MR is associated with a progressive cardiac remodeling with enlargement and dysfunction of all cardiac chambers, and the development of functional tricuspid regurgitation (TR ...

In degenerative mitral regurgitation a combined speckle tracking analysis predicts right ventricular to pulmonary circulation uncoupling

European Heart Journal - Cardiovascular Imaging
Abstract Background Global Longitudinal Strain (GLS) and left atrial (LA) strain evaluation by Speckle Tracking Echocardiography (STE) have emerged as prognostic index in patients affected by degenerative mitral regurgitation (DMR). In this setting, the coupling between right ventricular (RV) function
