The Value of Right Ventricular Longitudinal Strain in the Evaluation of Adult Patients With Repaired Tetralogy of Fallot: a New Tool for a Contemporary Challenge [PDF]

, 2017
OBJECTIVE: The role of right ventricular longitudinal strain for assessing patients with repaired tetralogy of Fallot is not fully understood. In this study, we aimed to evaluate its relation with other structural and functional parameters in these ...

Valoración de la función contráctil del ventrículo derecho por deformación en escala de grises bidimensional en una población con hipertensión pulmonar [PDF]

, 2005
Quantification of right ventricular function continues to evolve, even though his assessment is difficult due to the complex geometry of this cardiac chamber.Objectiveto characterize right ventricular function by calculating the strain, the longitudinal ...

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.

Evaluation of right and left ventricular function using speckle tracking echocardiography in patients with arrhythmogenic right ventricular cardiomyopathy and their first degree relatives

Cardiovascular Ultrasound, 2012
Introduction and aim The identification of right ventricular abnormalities in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) in early stages is still difficult.

Late deterioration of left ventricular function after right ventricular pacemaker implantation [PDF]

, 2015
Objectives: Right ventricular (RV) pacing induces a left bundle branch block pattern on ECG and may promote heart failure. Patients with dual chamber pacemakers (DCPs) who present with progressive reduction in left ventricular ejection fraction (LVEF ...

Right Ventricular Function, Peripheral Edema, and Acute Kidney Injury in Critical Illness

Kidney International Reports, 2017
The cardiorenal syndrome generally focuses on left ventricular function, and the importance of the right ventricle as a determinant of renal function is described less frequently. In a cohort of critically ill patients with echocardiographic measurements

Echocardiographic Evaluation of Right Ventricular Function [PDF]

European Journal of Echocardiography, 2002
To allow optimal patient management an ideal measure of right ventricular performance should give an accurate objective assessment of function, be practicable in everyday clinical use and provide accurate prognostic information. This review will provide the practising clinician with an understanding of the advantages and disadvantages of the available ...

Autonomic regulation therapy to enhance myocardial function in heart failure patients: the ANTHEM-HFpEF study. [PDF]

, 2017
BackgroundApproximately half of the patients presenting with new-onset heart failure (HF) have HF with preserved left ventricular ejection fraction (HFpEF) and HF with mid-range left ventricular ejection fraction (HFmrEF).

Right Ventricular Plasticity and Functional Imaging [PDF]

Pulmonary Circulation, 2012
Right ventricular (RV) function is a strong independent predictor of outcome in a number of distinct cardiopulmonary diseases. The RV has a remarkable ability to sustain damage and recover function which may be related to unique anatomic, physiologic, and genetic factors that differentiate it from the left ventricle. This capacity has been described in

Beta-blockers, left and right ventricular function, and in-vivo calcium influx in muscular dystrophy cardiomyopathy.

PLoS ONE, 2013
Beta-blockers are used to treat acquired heart failure in adults, though their role in early muscular dystrophy cardiomyopathy is unclear. We treated 2 different dystrophic mouse models which have an associated cardiomyopathy (mdx: model for Duchenne ...
