Alterations in right ventricular pumping in patients with atrial septal defect at rest and during dobutamine stress
نویسندگان
چکیده
Background CMR can provide details on ventricular pumping by subdividing the contribution to stroke volume (SV) into longitudinal shortening and radial inward motion of the ventricular borders. Previous studies have shown that patients with volume loaded dilated right ventricles (RV) due to pulmonary regurgitation (PR) have decreased longitudinal contribution to RVSV. Patients with atrial septal defects (ASD) also have volume loaded dilated RVs but it is not known if this affects longitudinal shortening.

Changes in blood volume shunting in patients with atrial septal defects: assessment of heart function with cardiovascular magnetic resonance during dobutamine stress
Background The purpose of this study was to determine the effect of stress on left-to-right shunting in patients with atrial septal defect (ASD) and to investigate if the degree of shunting, cardiac output (CO), and right ventricular (RV) volumes are related to exercise capacity. Methods Twenty-six patients with a secundum ASD and 16 healthy volunteers were studied with rest/stress cardiac ma...
متن کاملFactors determining exercise capacity in patients with atrial septal defect: assessment of heart function with CMR during dobutamine stress
Background Patients with left to right shunting of blood through an atrial septal defect (ASD) have decreased exercise capacity. This study hypothesized that central factors influence exercise capacity, namely systemic and pulmonary cardiac output and right ventricular (RV) function during stress as well as left atrial pressure (LAP) and pulmonary artery pressure (PAP). Previous studies have fo...

Introduction: In this study, we sought to illustrate our experience in urgent surgical management for embolized cardiac septal occlude devices resulting from trans-catheter closure of atrial septal defect and ventricular septal defect. Mathrials and Methods: We retrospectively reviewed four patients aged 2–10 years who underwent urgent surgery due to cardiac septal occluder embolization between...

ume overload was created in open-chest dogs by pumping blood from the left atrium to the right atrium. In seven of eight dogs changes in interventricular septum motion were produced acutely at shunt flow as low as 500 cc/min. When the shunt was decreased or stopped, interventricular septum motion returned to normal. Shunts producing left ventricular volume overload (aorta to left atrium and rig...
متن کاملRelation of biventricular function quantified by stress echocardiography to cardiopulmonary exercise capacity in adults with Mustard (atrial switch) procedure for transposition of the great arteries.
BACKGROUND Mustard repair for transposition of the great arteries (TGA) is frequently associated with impaired systemic (right) ventricular function and sometimes exercise intolerance. We hypothesized that a simple quantitative measurement of ventricular function, during rest and pharmacological stress, could identify abnormalities and predict objective exercise capacity. METHODS AND RESULTS ...
