Chronic Pressure-Overload Hypertrophy Attenuates Vortex Formation Time in Patients With Severe Aortic Stenosis and Preserved Left Ventricular Systolic Function Undergoing Aortic Valve Replacement
Objective: Transmitral blood flow produces a vortex ring that enhances the hydraulic efficiency of early left ventricular (LV) filling. The effect of pressure-overload hypertrophy on the duration of LV vortex ring formation (vortex formation time [VFT]) is unknown. The current investigation tested the hypothesis that chronic LV pressure-overload hypertrophy produced by severe aortic stenosis (AS) reduces VFT in patients with preserved LV systolic function undergoing aortic valve replacement.Design: Observational study.Setting: Veterans Affairs Medical Center.Participants: After the Institutional Review Board's approval, 8 ...

Transcatheter Aortic Valve Replacement
The percutaneous transcatheter aortic valve replacement (TAVR) procedure, introduced in 2002, has emerged as a successful and comparable treatment option for many patients with aortic stenosis. Balanced general anesthesia or monitored anesthesia care in addition to local anesthesia have been used during transfemoral and transapical approaches. The results of different TAVR registries and the PARTNER trial have shown excellent success and survival rates, but stroke and paravalvular insufficiency represent major concerns. The key for successful procedural outcome involves thorough preparedness and knowledge of the pertinent procedural details.
