Mitral valve prolapse: comparative value of m-mode, two-dimensional and doppler echocardiography.
M-mode, two-dimensional and Doppler echocardiography were used to assess the comparative value of each in the detection of clinically diagnosed mitral valve prolapse; 125 consecutive patients with a mid- to late systolic click, with or without a late systolic murmur, were included. There were 46 men and 79 women; their mean age was 42 years. M-mode echocardiography detected 62 of 125 cases (sen...
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 کاملDoppler Assessment of Prosthetic Valve Orifice Area
Background. Although Doppler echocardiography has been shown to be accurate in assessing stenotic orifice areas in native valves, its accuracy in evaluating the prosthetic valve orifice area remains undetermined. Methods and Results. Doppler-estimated valve areas were studied for their agreement with catheterderived Gorlin effective orifice areas and their flow dependence in five sizes (19/20-2...
متن کاملEditorial: Comparison of M-mode and Two-dimensional Echocardiography
IN THE PRECEDING ARTICLE in this issue of Circulation, Wann et al. compare features of M-mode and two-dimensional echocardiography as used in patients with infective endocarditis. Their discussion should arouse curiosity about the implied conflict between M-mode and the newer, two-dimensional approach for general ultrasonic imaging of the heart. M-mode echocardiography has well-known capabiliti...
