Regional pulmonary blood flow after mitral valve surgery.
The authors investigated the index ofpulmonary bloodflow distribution between the upper and lower parts of the lungs in three groups ofpatients with acquired valvular heart disease before, and 3 and 12 months after surgical correction for mitral and aortic valve disease. Three and 12 months after mitral valvotomy, there was a statistically significant decrease in the perfusion of the upper part...
متن کاملRegional Pulmonary Blood Flow
unteers were studied, nine sitting and seven supine. During hypoxia there was a slight but significant increase in relative perfusion of the upper portions of the lungs in both the sitting and supine subjects. During recovery from hypoxia, blood flow distribution differed significantly from the control. The erect subjects showed increased relative perfusion of the lung bases and the supine subj...
متن کاملRight sided heart evaluation after successful mitral valve replacement.
Introduction: It is well-documented that right-sided heart dysfunction and significant tricuspid valve regurgitation (TVR) have adverse effects on patient outcomes after left-sided heart valve surgery. Therefore, the evaluation of right ventriclular (RV) function and TR severity in patients who had undergone mitral valve replacement (MVR), associated with/without concomitant su...
متن کاملEvaluation of diastolic blood flow dynamic of the left ventricle in dogs with mitral valve regurgitation using vector flow mapping
Mitral valve regurgitation (MVR) is a common valvular disease in dogs. Hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (VFM), which shows the blood flow within the ventricles in vector and vortex flows. Blood flow within the left ventricle of MVR dogs was compared at different stages of MVR and to that of normal dogs. 14 normal dogs and...
متن کاملEndoscopic mitral and tricuspid valve surgery after previous cardiac surgery.
BACKGROUND The purpose of this study was to evaluate the feasibility and effectiveness of a right video-assisted approach for atrioventricular valve disease after previous cardiac surgery. METHODS AND RESULTS Between December 1st 1997 and May 1st 2006, 80 adults (mean age 65+/-12 years; 56% female) underwent reoperative surgery using a video-assisted approach without rib spreading. Previous c...
