Basal Interventricular Septal Aneurysm in Rheumatic Mitral Stenosis

even in that cases, the basal portion of the muscular IVS is spared. Our patient had a well defined aneurysm of the basal IVS which was contractile in nature. The mechanism behind the development of aneurysm in our case might be the eccentric jet of mitral stenosis constantly striking the basal IVS region. Aneurysmal deformity of the basal IVS secondary to impinging turbulent transprosthetic ec...

Thresholds in the sliding resistance of simulated basal ice

We report laboratory determinations of the shear resistance to sliding melting ice with entrained particles over a hard, impermeable surface. With higher particle concentrations and larger particle sizes, Coulomb friction at particlebed contacts dominates and the shear stress increases linearly with normal load. We term this the sandy regime. When either particle concentration or particle size ...

Collateral cerebral vascular resistance in patients with significant carotid stenosis.

This study tests, the hypothesis that asymptomatic patients with hemodynamically significant internal carotid artery stenosis have a lower ipsilateral collateral cerebral vascular resistance and hence greater blood flow than their symptomatic cohorts. We measured internal carotid artery blood flow and cerebral perfusion pressures intraoperatively prior to and after carotid endarterectomy in 35 ...

Coronary microcirculatory resistance is independent of epicardial stenosis.

BACKGROUND Recent studies show that coronary microcirculatory impairment is an independent predictor of poor outcomes in patients with cardiovascular disease. However, controversy exists over whether microcirculatory resistance, a measure of coronary microcirculatory status, is dependent on epicardial stenosis severity. Previous studies demonstrating that microcirculatory resistance is dependen...
