Outcomes

Primary Outcomes

Presence of mitral splay sign

Time Frame: 1 year

Logical, Presence of splay sign -- wide linear color doppler artifact on the level of valve coaptation disproportional to the width of the regurgitant jet

Presence of narrow doppler bands

Time Frame: 1 year

Logical, presence of narrow bands during continuous doppler echocardiography assessed by two echocardiographers (one blinded)
