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...

Methods A total of 43 consecutive patients (age 44 10 years) with moderate to severe PVS referred to Royal Brompton Hospital from 2002 to 2005 were retrospectively studied. Patient New York Heart Association (NYHA) functional class was recorded. The RV (lateral tricuspid annulus motion) long-axis movement was measured by M-mode and pulsed-wave (PW) tissue Doppler imaging (TDI). Restrictive RV p...

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 ...

conclusions chronic smoking caused left ventricular diastolic dysfunction. acute intake caused left and right ventricular diastolic dysfunction. changes persisted up to 30 minutes after smoking, although diastolic blood pressure returned to normal state. objectives the current study aimed to evaluate the acute and chronic effects of smoking on the left and right ventricular (rv) diastolic funct...

Right ventricular failure after cardiac surgery is a difficult clinical dilemma. We review the physiology of right ventricular failure in addition to current management strategies to address it.

conclusions there is a significant increased incidence of mortality, prolonged hospitalization, and rehospitalization in symptomatic patients with severe tr. therefore, we recommend more aggressive approach toward tv repair or replacement in these patients regardless of pap and systolic function. results heart failure (50%) was the most cause of death. mean years of survival from diagnosis of s...

background: diabetes mellitus is capable of impairing the myocardial function. several studies have documented the influential impact of diabetes mellitus on the left ventricular function. the right ventricular function plays a significant role in the overall myocardial contractility; hence, this study was undertaken to evaluate the effect of diabetes mellitus type ii on the right ventricular f...

BACKGROUND A paradoxical inspiratory rise in right atrial pressure (in contrast to the normal fall during inspiration), Kussmaul sign, has been described in congestive heart failure (CHF). However, the clinical and hemodynamic characteristics and clinical outcomes of patients with CHF and Kussmaul physiology have not been studied. METHODS AND RESULTS This is a single-center study of consecuti...
