Percutaneous Mitral Valve Repair for Mitral Regurgitation

Journal of Interventional Cardiology, 2003
Mitral regurgitation (MR) associated with, ischemic, and degenerative (prolapse) disease, contributes to left ventricular (LV) dysfunction due to remodeling, and LV dilation, resulting in worsening of MR. Mitral valve (MV) surgical repair has provided improvement in survival, LV function and symptoms, especially when performed early.

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

The Journal of Physiology, EarlyView.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

Acute intermittent hypercapnic hypoxia augments left ventricular contractility

The Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

Surgical repair of congenital mitral valve malformations

, 2010
Surgical development of mitral valve repair techniques in pediatric patients has been slow because of the great variety in the presentation of congenital mitral valve malformations and the still unknown growing effect over the complex mitral valve ...

Unveiling sex dimorphism in the healthy cardiac anatomy: Fundamental differences between male and female heart shapes

The Journal of Physiology, EarlyView.
Abstract figure legend We present a shape modelling‐based morphological analysis of sex differences in cardiac anatomy. We conduct our analysis on 456 healthy subjects from the UK Biobank (227M/229F) to uncover sex‐based differences in healthy cardiac morphology.

Progression of mitral regurgitation following ischemic mitral valve repair

, 2007
Objective. Durability of mitral valve repair for ischemic mitral regurgitation remains questionable. The aim of our study was to reveal predictors of recurrent mitral regurgitation following ischemic mitral valve repair. Material and methods.

4D ultrasound reveals regional left atrial strain remodelling in a murine model of reversible pressure overload

The Journal of Physiology, EarlyView.
Abstract figure legend Traditional planar imaging approaches of the left atrium do not capture complex geometry. Four‐dimensional imaging allows the acquisition of 3D data + time to visualize left atrial geometry and kinematics. We designed an advanced analysis technique to investigate left atrial biomechanics in a model of pressure overload and ...

Comparative multimodal calibration of patient‐specific atrial fibrillation models: Impact of imaging and electrophysiology data on arrhythmogenic substrate identification

The Journal of Physiology, EarlyView.
Abstract figure legend Comparative multimodal calibration of patient‐specific left atrial (LA) models to identify arrhythmogenic substrates in atrial fibrillation (AF). A, LA models shown in posterior and anterior views, calibrated separately using: late gadolinium enhancement magnetic resonance imaging (LGE‐MRI) image intensity ratio (IIR; blue–red ...
