BACKGROUND Mitral regurgitation (MR) of mitral valve prolapse predominates in late systole but may be holosystolic or purely mid-late systolic, but the impact of MR timing on MR left ventricular and left atrial consequences and outcome is unknown. Whether effective regurgitant orifice (ERO) by the flow convergence method is similarly linked to outcome in mid-late systolic MR and holosystolic MR...

Background—Mitral regurgitation (MR) of mitral valve prolapse predominates in late systole but may be holosystolic or purely mid-late systolic, but the impact of MR timing on MR left ventricular and left atrial consequences and outcome is unknown.

V and echocardiography 3 studies have demonstrated that in some subjects, the syndrome of midsystolic click and late systolic murmur4 is based on late systolic prolapse of mitral valve leaflets. We present here external carotid pulse tracings obtained from patients with angiographically documented prolapse of posterior mitral valve leaflets. All subjects had normal coronary arteriograms; there ...

Systolic obstruction of the left ventricular outflow tract, either at rest or during provocation, is a frequent finding in patients with hypertrophic cardiomyopathy. Mid-cavity obstruction is uncommon, and intraventricular diastolic pressure gradients in association with either mid-cavity of apical hypertrophy are reported only rarely. We describe a patient with hypertrophic cardiomyopathy with...

In this paper, we investigate interactions with distant interfaces. In particular, we focus on how to issue mouse click like commands in mid-air and we propose a taxonomy for distant one-arm clicking gestures. The gestures are divided into three main groups based on the part of the arm that is responsible for the gesture: the fingers, the hand, or the arm. We evaluated nine specific gestures in...
