DEPARTMENT of CARDIOVASCULAR SURGERY Quantification of Mitral Valve Regurgitation by Left Ventricular Volume and Flow Measurements Using Electron Beam Computed Tomography: Comparison with Magnetic Resonance Imaging
ثبت نشده
چکیده
Method Forty-three patients, among them 33 with known mitral regurgitation, underwent electron beam CT and MR imaging. Total left ventricular stroke volume (TSV), antegrade stroke volume (ASV), and mitral regurgitation volume (MRV) and fraction (MRF) were determined and compared between the two modalities. Additionaly electron beam CT measurements were compared with the corresponding echocardiographic findings.

Assessment of mitral valve regurgitation at electron-beam CT: comparison with Doppler echocardiography.
PURPOSE To prospectively compare mitral valve regurgitation fractions calculated at electron-beam computed tomography (CT) (Doppler echocardiography as reference standard) and to evaluate accuracy of electron-beam CT volume and flow measurements compared with magnetic resonance (MR) imaging results. MATERIALS AND METHODS Institutional review board approval and informed consent were obtained. ...
متن کاملRight ventricular Hemodynamic Alteration after Pulmonary Valve Replacement in Children with Congenital Heart Disease
Introduction: In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...
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 کاملQuantification of the Mitral Regurgitant Flow Using a Control Volume Method: in Vitro Evaluation Using Ultra-fast Magnetic Resonance Velocimetry
INTRODUCTION Reliable diagnosis of the severity of mitral regurgitation is important for proper patient treatment and management. However, current clinical methods are either qualitative or limited by geometric assumptions. The only technique capable of bypassing these geometric limitations and quantitatively measure mitral regurgitation is velocity encoded magnetic resonance (MR) imaging, also...

Certain subsets of high-risk mitral valve patients are not suitable candidates for transcatheter therapies. The objective of this report is to present a young patient with combined mitral valve and coronary artery disease to illustrate these challenges.In this report, we present a 47-year-old man with longstanding HIV infection who was referred with severe mitral regurgitation (MR) and profound...
