Clinical implications for diffusion‐weighted MRI brain lesions associated with transcatheter aortic valve replacement
Transcatheter aortic valve replacement (TAVR) is increasingly used to treat patients with aortic stenosis deemed high or extreme surgical risk candidates. Despite improved survival and quality of life following the procedure, TAVR is not without its complications. Stroke is a major source of morbidity and mortality in patients undergoing the procedure, with rates similar to and often higher than those associated with surgery. Most studies show a consistent link between TAVR and embolic lesions visualized on diffusion‐weighted magnetic resonance imaging. The question of whether these lesions lead to long‐term cognitive ...

Transcatheter aortic valve implantation without balloon pre‐dilation: A single‐center pilot experience
Conclusions: These results suggest that direct CoreValve implantation in patients with severe aortic stenosis is feasible and may lead to hemodynamic and clinical improvement in patients who are poor candidates for aortic valve surgery, pending confirmation in larger series with longer follow‐up. © 2013 Wiley‐Liss, Inc.

Single center TAVR experience with a focus on the prevention and management of catastrophic complications
Conclusions: TAVR can be accomplished with excellent safety in a tertiary center with a well‐developed infrastructure for the management of serious complications. The data presented here provide support for TAVR as an important treatment option, and results from randomized trials of patients with lower surgical risk are eagerly awaited. © 2014 Wiley Periodicals, Inc.

Feasibility and safety of transfemoral implantation of Edwards SAPIEN XT prosthesis without balloon valvuloplasty in severe stenosis of native aortic valve
ConclusionsDirect implantation of Edwards SAPIEN XT without prior BV in selected cases is feasible and safe. The number of patients in whom this technique would be applicable, and their impact on reducing complications has to be determined. © 2013 Wiley Periodicals, Inc.

Prevalence and predictors of carotid artery stenosis in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation
Conclusions: The prevalence of CAS in patients undergoing TAVI is high, exceeding that observed in patients undergoing catheterization for coronary indications. The impact of CAS on clinical outcomes following TAVI merits further research. © 2014 Wiley Periodicals, Inc.

A novel approach to extraction of a large thrombus on the intraventricular guide‐wire during transcatheter aortic valve replacement
We report a case where a large guide‐wire thrombus identified during TAVR was successfully removed using a novel approach, preventing a potentially major stroke in this high‐risk patient. © 2015 Wiley Periodicals, Inc.

Efficacy and safety of transcatheter aortic valve replacement in intermediate surgical risk patients: A systematic review and meta‐analysis
ConclusionsIn this meta‐analysis we found that TAVR may be an acceptable alternative to SAVR in patients with intermediate risk for surgery. However, we must await evidence from the current large randomized trials before widespread adoption of this procedure is undertaken. © 2016 Wiley Periodicals, Inc.

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...

Feasibility and efficacy of the 2.5L and 3.8L Impella percutaneous left ventricular support device during high‐risk, percutaneous coronary intervention in patients with severe aortic stenosis
Conclusion: Implantation of the 2.5 and 3.8L Impella appears feasible in patients with severe AS and LV impairment. A balloon‐assist technique may be used to facilitate device implantation when initial unassisted attempts fail. Improved hemodynamic stability may enhance the tolerability of lengthy and complex procedures. © 2014 Wiley Periodicals, Inc.

Echocardiographic determinants of LV functional improvement after transcatheter aortic valve replacement
ConclusionsIn patients undergoing TAVR with depressed LV function, those who failed to improve were more likely to have relatively higher LVEF, SV, and SVI; and lower E, E/E′, and PASP at baseline. Mortality rates were found to be higher in persistent LV dysfunction group. © 2015 Wiley Periodicals, Inc.
