Predominant right ventricular dysfunction after right ventricular destruction in the dog

The American Journal of Cardiology, 1974
Abstract Right and left ventricular function was assessed by observing the response to rapid blood volume expansion before and after extensive cauterization of the right ventricle in open chest dogs. In the control period, left ventricular end-diastolic pressure surpassed right ventricular end-diastolic pressure by an average of 11.5 mm Hg after ...

Right Ventricular Dysfunction Due to Right Ventricular Outflow Tract Patch

Asian Cardiovascular and Thoracic Annals, 2006
Doppler tissue imaging analysis was used to examine the relationship between right ventricular function and right ventricular outflow tract damage in 54 patients with repaired tetralogy of Fallot. The patients were divided into three groups: 16 in whom the right ventricular outflow tract was directly sutured (group DS), 23 who had transventricular ...

Right ventricular dysfunction in acute ventricular septal defect

American Heart Journal, 1981
Eight patients with acute ventricular septal defect (VSD) receiving early intra-aortic balloon augmentation, cardiac catheterization, and open-heart surgery are described. Because of the large shunts in this group of patients, there was visualization of the right ventricle during left ventriculography which was adequate for qualitative analysis.

Right ventricular diastolic dysfunction and failure: a review

Heart Failure Reviews, 2021
Right ventricular diastolic dysfunction and failure (RVDDF) has been increasingly identified in patients with cardiovascular diseases, including heart failure and other diseases with cardiac involvement. It is unknown whether RVDDF exists as a distinct clinical entity; however, its presence and degree have been shown to be a sensitive marker of end ...

Right Ventricular Dysfunction and Long-Term Risk of Sudden Cardiac Death in Patients With and Without Severe Left Ventricular Dysfunction

Circulation: Arrhythmia and Electrophysiology, 2018
Background: Right ventricular systolic dysfunction (RVD) often coexists with various cardiopulmonary diseases. However, the association between RVD and risk of sudden cardiac death (SCD) has not been well studied.

Right Ventricular “Bubble Time” to Identify Patients With Right Ventricular Dysfunction

Annals of Emergency Medicine
We propose a novel method of evaluating right ventricular (RV) dysfunction in the emergency department (ED) using RV "bubble time"-the duration of time bubbles from a saline solution flush are visualized in the RV on echocardiography. The objective was to identify the optimal cutoff value for RV bubble time that differentiates patients with RV ...

Right Ventricular Dysfunction and Ischemia in Pulmonary Embolism

Revista Española de Cardiología (English Edition), 2004
Patients with pulmonary embolism and right ventricle dysfunction (determined with clinical, hemodynamic or echocardiographic methods) are a subgroup at high risk for complications. One of the pathogenic factors of right ventricular dysfunction in pulmonary embolism is myocardial ischemia, usually secondary to hemodynamic overload, and sometimes ...

Right Ventricular Dysfunction in Pulmonary Hypertension [PDF]

, 2010
We now know that there are many key differences between the right ventricle (RV) and the left ventricle (LV), ranging from embryological origin, structure, function (metabolism and perfusion), neurohormonal activation and response to increased afterload.
