Influence of advanced pulmonary vascular remodeling on accuracy of echocardiographic parameters of left ventricular filling pressure

Pulmonary Circulation, 2021
Evaluation of left ventricular filling pressure plays an important role in the clinical management of pulmonary hypertension. However, the accuracy of echocardiographic parameters for the determination of left ventricular filling pressure in the presence

Physiological and clinical consequences of relief of right ventricular outflow tract obstruction late after repair of congenital heart defects. [PDF]

, 2006
BACKGROUND: Right ventricular outflow tract obstruction (RVOTO) is a common problem after repair of congenital heart disease. Percutaneous pulmonary valve implantation (PPVI) can treat this condition without consequent pulmonary regurgitation or ...

Improvement of left ventricular systolic function after intervention on right ventricular hemodynamics

Annals of Pediatric Cardiology
Background: The importance of right–left ventricular interactions is increasingly recognized in patients with congenital heart disease. Interventions to improve right ventricular volume/pressure overloading may result in improvement of left ventricular ...

Combined pressure and volume loading for left ventricular training in patients with congenitally corrected transposition of the great arteriesCentral MessagePerspective

JTCVS Open
Objective: Patients with congenitally corrected transposition of the great arteries may require left ventricular training before the double switch operation. We evaluated the effects of combined pressure and volume loading.

Norepinephrine and dobutamine improve cardiac index equally by supporting opposite sides of the heart in an experimental model of chronic pulmonary hypertension

Intensive Care Medicine Experimental, 2021
Background Pulmonary hypertension is a significant risk factor in patients undergoing surgery. The combined effects of general anaesthesia and positive pressure ventilation can aggravate this condition and cause increased pulmonary blood pressures ...

The Diverse Neuromuscular Spectrum of VPS13A Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective VPS13A disease (chorea‐acanthocytosis) is a rare neurodegenerative disorder caused by biallelic variants in VPS13A, typically presenting with hyperkinetic movement disorders, while neuromuscular signs are often mild. The aim of the project was to investigate the frequency and severity of neuromuscular impairment in VPS13A disease ...
