Dyssynchrony Assessment with Tissue Doppler Imaging and Regional Volumetric Analysis by 3D Echocardiography Do Not Predict Long-Term Response to Cardiac Resynchronization Therapy
Background. Currently there are no reliable predictors of response to cardiac resynchronization therapy (CRT) before implantation. We compared pre-CRT left ventricular (LV) dyssynchrony by tissue Doppler imaging (TDI) and regional volumetric analysis by 3-dimensional transthoracic echocardiography (3DTTE) in predicting response to CRT. Methods. Thirty-eight patients (79% nonischemic cardiomyopa...
متن کاملAssessment of left ventricular dyssynchrony and cardiac function in patients with different pacing modes using real-time three-dimensional echocardiography: Comparison with tissue Doppler imaging
The aim of this study was to evaluate the left ventricular mechanical dyssynchrony (LVMD) and left ventricular dysfunction of patients in AAI, DDD and VVI pacing modes using real-time three-dimensional echocardiography (RT3DE) and tissue Doppler imaging (TDI). The results from the RT3DE and TDI were subsequently compared. Twenty patients with sick sinus syndrome (SSS) who had undergone the impl...
متن کاملComparison between M-Mode and Doppler echocardiography in diagnosis
Introduction: Patent ductus arteriosus (PDA) is the persistence of a normal fetal structure between left pulmonary artery and descending aorta. Persistence of this fetal structure beyond 10 days of life is considered abnormal. In this study we compared M-Mode and Doppler echocardiography in diagnosis of PDA in children at Aliasghar Hospital in Zahedan and Children hospital in Bandar Abbas for...
متن کاملAssessment of Atrial Septal Defect Role of Real-Time 3D Color Doppler Echocardiography for Interventional Catheterization
Background: Atrial septal defect (ASD) is easily thought to be a round hole in the atrial septum from the image of two-dimensional (2D) echocardiography. Even surgeons can not get the true morphology of an atrial septal defect because they only see the defect when the heart is already in a collapsed, non-beating condition. Pediatric interventional cardiologists, on the contrary, need to know th...
متن کامل3D Echocardiography of the LV and RV
The evaluation of the global and regional left ventricular (LV) function is an essential part of a routine perioperative TEE-examination. To date, the assessment of the LV ejection fraction (EF) is mainly performed by “eye-balling”, which relies on the echocardiographer’s experience and ability to visually integrate spatial information. Further limitations of 2D-TEE assessment of the LV EF are ...
