Right ventricular Hemodynamic Alteration after Pulmonary Valve Replacement in Children with Congenital Heart Disease [PDF]

Journal of Cardio-Thoracic Medicine, 2015
Introduction:  In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest.

Echocardiographic evaluation of the systemic ventricle after atrial switch procedure. The usefulness of subcostal imaging [PDF]

, 2008
Background: Subcostal planes allow demonstration of the entire right ventricular cavity and are frequently used in patients with congenital heart disease; however, their clinical utility in the evaluation of systemic right ventricular function after ...

Skeletal myoblast sheet transplantation improves the diastolic function of a pressure-overloaded right heart [PDF]

, 2009
ObjectiveThe development of right ventricular dysfunction has become a common problem after surgical repair of complex congenital heart disease. A recent study reported that tissue-engineered skeletal myoblast sheet transplantation improves left ...

Biologically‐Inspired Melt Electrowriting for the Generation of Highly Biomimetic Functional Myocardium

Advanced Functional Materials, EarlyView.
In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

Effect of preoperative right ventricular dysfunction and dilatation on survival after left ventricular surgical restoration

The Cardiothoracic Surgeon
Background This study investigated the impact of preoperative right ventricular (RV) dysfunction and dilatation on survival outcomes following left ventricular surgical restoration (LVSR) in patients with ischemic cardiomyopathy. A retrospective analysis

Right ventricular function as assessed by cardiac magnetic resonance imaging‐derived strain parameters compared to high‐fidelity micromanometer catheter measurements

Pulmonary Circulation, 2021
Right ventricular function has prognostic significance in patients with pulmonary hypertension. We evaluated whether cardiac magnetic resonance‐derived strain and strain rate parameters could reliably reflect right ventricular systolic and diastolic ...

Evidence that conflict regarding size of haemodynamic response to interventricular delay optimization of cardiac resynchronization therapy may arise from differences in how atrioventricular delay is kept constant. [PDF]

, 2014
Aims: Whether adjusting interventricular (VV) delay changes haemodynamic efficacy of cardiac resynchronization therapy (CRT) is controversial, with conflicting results.

Spontaneous Degenerative Aortic Valve Disease in New Zealand Obese Mice [PDF]

, 2021
Background: Degenerative aortic valve (AoV) disease and resulting aortic stenosis are major clinical health problems. Murine models of valve disease are rare, resulting in a translational knowledge gap on underlying mechanisms, functional consequences ...

Ischemic Myocardium Targeting Peptide‐Guided Nanobubbles for Multimodal Imaging and Treatment of Coronary Microvascular Dysfunction

Advanced Healthcare Materials, EarlyView.
Nanobubbles functionalized with indocyanine green and ischemic myocardium‐targeting peptide effectively target cardiomyocytes and enable the multimodal (fluorescence, ultrasonic, and photoacoustic) imaging of ischemic myocardium in mice with coronary microvascular dysfunction (CMD).

Echocardiographic assessment of right ventricular systolic function.

Cardiovascular Diagnosis and Therapy, 2018
Assessment of right chamber function has become increasingly popular and important in recent decades, complementing the evaluation of left chamber functional parameters. The late adoption and integration of right ventricular (RV) function into a complete
