Moderate Aortic Valvular Insufficiency Invalidates Vortex Formation Time as an Index of Left Ventricular Filling Efficiency in Patients With Severe Degenerative Calcific Aortic Stenosis Undergoing Aortic Valve Replacement

Publikováno v: Journal of Cardiothoracic and Vascular Anesthesia. 30:1260-1265

Objective Transmitral blood flow produces a vortex ring (quantified using vortex formation time [VFT]) that enhances the efficiency of left ventricular (LV) filling. VFT is attenuated in LV hypertrophy resulting from aortic valve stenosis (AS) versus

Publikováno v: Journal of Visualized Experiments.

Trans-mitral blood flow produces a three-dimensional rotational body of fluid, known as a vortex ring, that enhances the efficiency of left ventricular (LV) filling compared with a continuous linear jet. Vortex ring development is most often quantifi

Aortic Valve Replacement Reduces Valvuloarterial Impedance but Does Not Affect Systemic Arterial Compliance in Elderly Men With Degenerative Calcific Trileaflet Aortic Valve Stenosis

Autor: Andrew R. Schroeder, Paul S. Pagel, Judith A. Hudetz, Derek J. De Vry

Publikováno v: Journal of Cardiothoracic and Vascular Anesthesia. 28:1540-1544

Standard methods of quantifying aortic valve stenosis (AS), which focus entirely on the valve itself, do not adequately characterize the magnitude, predict the onset, progression, and severity of symptoms, or identify the incidence of subsequent adve

Autor: David R. Ferron, Brittany N. Price, Paul S. Pagel, Ghulam Murtaza, Derek J. De Vry, Zahir A. Rashid

Publikováno v: Journal of cardiothoracic and vascular anesthesia. 30(2)

A59-YEAR-OLD, 92-kg, 178-cm man with a past medical history of chronic alcohol and tobacco abuse was referred to the authors’ institution by his primary care physician because a routine electrocardiogram found a new right bundle-branch block. The p
