Abstract

In this study, we observed diastolic Junction by using Doppler echocardiography during Valsalva, handgrip, standing and leg elevation maneuvers in patients with mitral regurgitation (MR). Patients population consisted of 32 patients with MR . Valsalva maneuver decreased E-velocity (%J2, p<0.05), A velocity (%8, p<0.05) but did not change E/A ratio (p>0.05). During the handgrip test, peak E and A velocity and E/A ratio did not change (p>0.05). During the leg elevation, E and A velocity were not changed (p<0.05), but E/A ratio was changed (%13, p<0.05). Standing decreased E-velocity (%11, p<0.05) and E/A ratio (%7, p<0.05) but did not changed A velocity (p>0.05).

Özet

Bu çalışmada mitral yetmezliği olan 32 hastada, Doppler ekokardiyografi kullanılarak, valsalva, handgrip, ayakta duruş ve ayakları kaldırma egzersizi sırasında diyastolik fonksiyon parametreleri incelendi. Valsalva manevrası sırasında E-dalgası (%12, p 0.05). El A oranı anlamlı olarak değişti. (%13, p 0.05).
