The ventricular septum: the lion of right ventricular function, and its impact on right ventricular restoration.
OBJECTIVE To evaluate the structure-function relationships of the right ventricle (RV) and septum and determine if the helical ventricular band model would define fiber orientation for maximal force response. Implications were made for right ventricular function. METHODS The right ventricular free wall and biventricular septum were studied by inserting sonomicrometer crystals at different ang...
متن کاملImpact of Endoscopic Lung Volume Reduction on Right Ventricular Myocardial Function
INTRODUCTION Endoscopic lung volume reduction (ELVR) provides a minimally invasive therapy for patients with severe lung emphysema. As its impact on right ventricular (RtV) function is undefined, we examined the extent of RtV functional changes following ELVR, as assessed by use of speckle tracking-based RtV deformation analysis. METHODS We enrolled 32 patients with severe emphysematous COPD ...
متن کاملDetermination of the Effects of Digoxin on the Right Ventricular Function in Patients Undergoing Pneumonectomy
Introduction: Pneumonectomy is the standard treatment of lung cancer, even though patients should undergo several evaluations before surgery; deterioration of cardiopulmonary function after pulmonary resection is inevitable. We have evaluated the effects of digoxin on the improvement of right ventricular function and prevention of probable complications after lung resection surgery. Materials a...
متن کاملRight ventricular volumes and function in thalassemia major patients in the absence of myocardial iron overload
AIM We aimed to define reference ranges for right ventricular (RV) volumes, ejection fraction (EF) in thalassemia major patients (TM) without myocardial iron overload. METHODS AND RESULTS RV volumes, EF and mass were measured in 80 TM patients who had no myocardial iron overload (myocardial T2* > 20 ms by cardiovascular magnetic resonance). All patients were receiving deferoxamine chelation a...
متن کاملMild pressure loading alters right ventricular function in fetal sheep.
Right ventricular function before and during 10 days of mild pressure loading (10 mm Hg increase in mean pulmonary arterial pressure) was compared with right ventricular function in unloaded near-term fetal sheep. Pressure loading did not alter fetal arterial blood gases or vascular pressures. The right ventricular function curve (stroke volume versus mean right atrial pressure) was not signifi...
