Mid-diastolic aortic valve opening in severe acute aortic regurgitation.

Abstract

ness and cavity size have not been studied previously in athletes. In this investigation, RVAW was increased in all participants and RV cavity was increased in most. Whether this increase in RVAW was part of the general hypertrophy which occurs in the heart of if this was related to prolonged elevation of pulmonary artery pressure during in-water training for 2-4 hours per day is not known. Clearly this is not an altitude factor alone since the previous normals were from the same community. We cannot explain why the aortic and aortic cusp separation measurements exceeded the 95th percentile of normal in most swimmers.In summary, the unique finding of this investigation is that children who participate extensively in training programs

A Case of Severe Aortic Regurgitation Caused by Takayasu's Arteritis Showing End-Diastolic Opening of Aortic Valve

“…As far as we know, diastolic opening of the AV in AR has been reported in 10 articles ( Table 1 ). 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 It was first reported by Page and Layton 1 in Marfan syndrome. Other conditions showing late diastolic opening of the AV were perforation of the leaflet secondary to infectious endocarditis, prolapse of the AV, and aortic dissection.…”

“…Diastolic opening of the aortic valve (AV) in severe AR is an exceptionally rare phenomenon, which could be caused by equalization of LV EDP and systemic blood pressure due to severely elevated LV EDP. 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 …”

A regurgitant jet and echocardiographic abnormalities in aortic regurgitation: an experimental study.

“…1-6 and 14), but it was not observed in dogs in which a regurgitant jet was directed to the posterior part of the IVS through which the beam did not pass (nos. [8][9][10][11][12][13]. This is probably related to the echo beam sampling of the anterior IVS in the present study.…”
