Dynamic changes of atrial septal defect area: new insights by three-dimensional volume-rendered echocardiography with high temporal resolution.
AIMS The purpose of this study was: (i) to record dynamic changes in the area of atrial septal defects (ASD) during a cardiac cycle, and (ii) to investigate factors which influence ASD dynamics. Implementation of new software modifications allowed the frame rate to be doubled, as compared to usual techniques. METHODS AND RESULTS Twenty patients were examined using transoesophageal three-dimen...
متن کاملRight atrial myxoma associated with an atrial septal defect by real-time three-dimensional echocardiography.
A 40-year-old woman presented with a 1 month history of shortness of breath and easy fatigability. Two-dimensional echocardiography and real-time three-dimensional echocardiography (RT3DE) showed a large right atrial mass protruding into the right ventricle and an atrial septal defect (ASD). Successful excision of the mass, which proved to be a myxoma, and closure of the ASD completely relieved...
متن کاملDynamic morphology of the secundum atrial septal defect evaluated by three dimensional transoesophageal echocardiography.
OBJECTIVE To define by three dimensional echocardiography the pattern and potential determinants of contraction of a secundum atrial septal defect through the cardiac cycle, and to evaluate the possibility of using cross sectional transthoracic and transoesophageal imaging to assess the dynamic nature of the defect. DESIGN Three dimensional echocardiography was performed using a multiplane tr...
متن کاملAssessment of atrial septal defect area changes during cardiac cycle by live three-dimensional echocardiography.
OBJECTIVES To investigate the accuracy of measurement of the atrial septal defect (ASD)area and dynamic change by live three-dimensional echocardiography (L3DE). METHODS L3DE was performed in patients with ASD using a three-dimensional workstation to obtain the en face view of the ASD and measure its area at the peak of P-wave, the peak of R-wave, the initial and the destination point of T-wa...
