One-year outcomes after transcatheter insertion of an interatrial shunt device for the management of heart failure with preserved ejection fraction [PDF]

, 2016
Background—Heart failure with preserved ejection fraction has a complex pathophysiology and remains a therapeutic challenge. Elevated left atrial pressure, particularly during exercise, is a key contributor to morbidity and mortality.

A novel clinical method for quantification of regional left ventricular pressure–strain loop area: a non-invasive index of myocardial work

European Heart Journal, 2012
Aims Left ventricular (LV) pressure–strain loop area reflects regional myocardial work and metabolic demand, but the clinical use of this index is limited by the need for invasive pressure.

Treatment of Left Ventricular Circulation Disorder: Application of Echocardiography Information Data Monitoring

JMIR Medical Informatics, 2020
BackgroundCardiac hypertrophy induced by pressure overload is one of the important causes of heart failure and sudden cardiac death. At present, there are few studies on the outcome of left ventricular hypertrophy and left ventricular function after ...

The relationship between left ventricular dilation and right ventricular diastolic function in children with a patent ductus arteriosus

Annals of Pediatric Cardiology, 2023
The impact of a dilated left ventricular (LV) on right ventricular (RV) diastolic function has not been investigated. We hypothesized that in patients with a patent ductus arteriosus (PDA), LV dilation causes elevation of the RV end-diastolic pressure ...

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 ...

Blood pressure-related electrocardiographic findings in healthy young individuals

Blood Pressure, 2020
Purpose: Elevated blood pressure induces electrocardiographic changes and is associated with an increase in cardiovascular disease later in life compared to normal blood pressure levels.

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

Ventricular pressures in phonating excised larynges [PDF]

The Journal of the Acoustical Society of America, 2012
Pressure in the laryngeal ventricle was measured with a beveled needle connected to a pressure transducer in excised canine larynges. Air pressures within the ventricle were obtained for different adduction levels of the true vocal folds (TVFs), false vocal folds (FVFs), and subglottal pressures (Ps).

Atrial Remodeling Is Directly Related to End-Diastolic Left Ventricular Pressure in a Mouse Model of Ventricular Pressure Overload

PLoS ONE, 2013
Background Atrial fibrillation (AF) is often preceded by underlying cardiac diseases causing ventricular pressure overload. Objective It was our aim to investigate the progression of atrial remodeling in a small animal model of ventricular pressure ...

Improved ventricular function during inhalation of PGI(2) aerosol partly relies on enhanced myocardial contractility [PDF]

, 2005
Inhaled prostacyclin (PGI(2)) aerosol induces selective pulmonary vasodilation. Further, it improves right ventricular ( RV) function, which may largely rely on pulmonary vasodilation, but also on enhanced myocardial contractility.
