Use of the ClearSight ® System for Continuous Noninvasive Hemodynamic Monitoring during Heart Valve Interventions: Review of the Literature and Single-Site Experience.
Use of the ClearSight® System for Continuous Noninvasive Hemodynamic Monitoring during Heart Valve Interventions: Review of the Literature and Single-Site Experience. Heart Surg Forum. 2018 Nov 14;21(6):E476-E483 Authors: Gellert G, Bramlage P Abstract During interventional and structural cardiology procedures, such as mitral valve (MitraClip, BMV), aortic valve (TAVR, BAV), tricuspid valve (MitraClip), left atrial appendage (Watchman, Lariat), atrial septum (ASD/PFO closure), and coronary artery intervention (high-risk PCI), among others, patients are at a high risk of hemodynamic instability and re...

Direct percutaneous transaxillary implantation of a novel self ‐expandable transcatheter heart valve for aortic stenosis
ConclusionsOur study suggests that the implantation of the second‐generation self‐expandable ACURATE Neo™ via a transaxillary access is technically feasible and safe and yields excellent short‐term clinical results. © 2017 Wiley Periodicals, Inc.

Acute Invasive Hemodynamic Effects of Transcatheter Aortic Valve Replacement.
CONCLUSIONS: Successful TAVR results in immediate and sizeable improvements in SV and CI, reductions in left and right ventricular filling pressures, and marked reductions in systemic and pulmonary vascular resistances. PMID: 27989060 [PubMed - in process]

Quantification of low-gradient severe aortic stenosis using a hybrid approach combining Doppler echocardiography and thermodilution.
CONCLUSION: The hybrid method is reasonably accurate in assessing AVA in patients with low-gradient severe AS. Although the continuity equation should be used in routine clinical practice in most patients, this method could serve as an alternative when the LVOT diameter and/or velocities seem questionable.

Invasive Hemodynamic Characteristics of Low Gradient Severe Aortic Stenosis Despite Preserved Ejection Fraction
Conclusions: Occurrence of low gradient severe aortic stenosis despite preserved ejection fraction was confirmed by invasive hemodynamics and was not the result of a systematic bias in the echo calculation of aortic orifice area.

Complications after transfemoral transcatheter aortic valve replacement with a balloon‐expandable prosthesis: The importance of preventative measures and contingency planning
Abstract Transcatheter aortic valve replacement (TAVR) with balloon‐expandable Edwards‐SAPIEN valve was superior to standard therapy in inoperable patients and non‐inferior to surgical aortic valve replacement in high surgical‐risk, but operable patients, with severe symptomatic aortic stenosis in the randomized controlled PARTNER trial. Since the first case of TAVR with a balloon‐expandable valve in 2002, several groups have reported their experience with balloon‐expandable valves with high‐procedural success. In the United States, the balloon‐expandable Edwards‐SAPIEN valve is the only transcatheter hea...
