the right ventricle (rv) is a complex structure with abstruse function that reveals important differences when compared to the left ventricle (lv), so it cannot be described as a simple geometric form and achromatic physiology. as an inference from this fact, in the present review, we aim to describe rv structure including the embryology, anatomy, and physiology and present a functional, hemody...

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. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...

Background: Assessment of myocardial function is essential in heart disease, but in regard to systolic and diastolic functions such evaluation has limitation. Ejection fraction is difficult to assess in abnormally-shaped ventricles, and diastolic inflow velocity pattern may be fused because of tachycardia. Objective: A myocardial performance index (MPI) or Tei index has been developed for adult...

OBJECTIVE: In animal models of aortic insufficiency, the right common carotid artery is typically used to damage valve leaflets; this strategy impedes subsequent assessments of left ventricular hemodynamics. The present study aimed to establish an alternative technique that would allow subsequent left ventricular catheterization to monitor sequential hemodynamics in rats with aortic insufficien...

Mansour and colleagues recommend not routinely using the pulmonary artery catheter to guide hemodynamic management in the intensive care unit, because the perceived benefits are largely intangible [1]. Pulmonary artery catheter monitoring of the right ventricular ejection fraction (RVef) and of the right ventricular end-diastolic volume (EDV), however, reflects powerful yet underutilized relati...

This study describes the clinical experience with four patients with variant angina caused by spasm of the right coronary artery who were assessed for evidence of right ventricular involvement. The patients were suspected of having predominant right ventricular ischemia on the basis of normal thallium-201 scans, left ventricular ejection fraction, regional wall motion assessed by equilibrium ra...

a pulmonary embolus clogs the artery that provides blood supply to a part of the lung. the embolus not only prevents the exchange of oxygen and carbon dioxide but also decreases blood supply to the lung tissue itself, potentially causing the tissue to die (infarct). a 52-year-old man presented with syncope and anxiety. he had sinus tachycardia and dilated right ventricle with trabeculations. a ...
