In eight adult dogs the main pulmonary artery was constricted to elevate the right ventricular peak systolic pressure to 50% of the peak aortic pressure at rest. The response of the right ventricle was assessed immediately, at 30 minutes and at six months. The right ventricle responded to acute systolic loading by complete compensation. After 30 minutes there was a reduction in the right ventri...

Right ventricular function plays an important role in determining cardiac symptoms and exercise capacity in chronic heart failure. It is known that right ventricle has complex anatomy and physiology. The purpose of this review paper is to demonstrate the best assessment of the right ventricle with current echocardiography. Echocardiography can assess sufficiently right ventricular structure and...

PURPOSE OF REVIEW To emphasize the importance and clinical implications of right ventricular function assessment in many situations encountered by intensivists and to explain in practical terms how to perform such an assessment at the bedside. RECENT FINDINGS Assessment of right ventricular function requires a full understanding of the physiology of the right ventricle. The right ventricle, u...

BackgroundIncreased metabolic rate of hyperglycemia in gestational diabetes causes macrosomia, which can also affect the fetal heart. The thickness of the walls of the heart and its function in women with gestational diabetes mellitus (GDM) can change over time before treatment. We aimed to evaluate fetal cardiac structure in terms of ventricular wall thickness and its function in women w...

Despite the importance of preserved right ventricular structure and function with respect to outcome across the spectrum of lung, cardiac, and pulmonary vascular diseases, only recently have organized efforts developed to consider the pulmonary vascular–right ventricular apparatus as a specific unit within the larger context of cardiopulmonary pathophysiology. The Third International Right Hear...

OBJECTIVES We hypothesized that a period of cuirass negative pressure ventilation (NPV) would augment the cardiac output of patients in the early postoperative period after complete correction of tetralogy of Fallot (TOF). BACKGROUND Diastolic right ventricular dysfunction can lead to a low-output state in an important minority of patients after TOF repair. In these patients, the diastolic pu...

Abstract Introduction The interpretation of cardiopulmonary exercise test (CPET) in adult congenital heart disease (ACHD) is challenging because the high variability cardiac lesions and poor tolerance often associated with abnormal function. aim this work to study correlation between echocardiographic evaluation CPET parameters ACHD population. Methods This a retrospective clinical enrolling al...
