Journal ArticleDOI
Transapical aortic valve implantation: step by step.
Thomas Walther,Todd M. Dewey,Michael A. Borger,Jörg Kempfert,Axel Linke,Reinhardt Becht,Volkmar Falk,Gerhard Schuler,Friedrich W. Mohr,Michael Mack +9 more
TL;DR: The aim of this article is to outline the technical aspects of the new technique of minimally invasive transapical aortic valve implantation using an oversizing technique with direct access and accurate positioning of a stent-based transcatheter xenograft.
Journal ArticleDOI
Comprehensive assessment of frailty for elderly high-risk patients undergoing cardiac surgery
Simon H. Sündermann,Anika Dademasch,Julian Praetorius,Jörg Kempfert,Todd M. Dewey,Volkmar Falk,Friedrich-Wilhelm Mohr,Thomas Walther +7 more
TL;DR: The comprehensive assessment of frailty is an additional tool to evaluate elderly patients adequately before cardiac surgical interventions and may facilitate a more accurate risk scoring in elderly high-risk patients scheduled for conventional cardiac surgery or trans-catheter aortic valve replacement.
Journal ArticleDOI
Transapical minimally invasive aortic valve implantation; the initial 50 patients.
Thomas Walther,Volkmar Falk,Jörg Kempfert,Michael A. Borger,Jens Fassl,Michael W.A. Chu,Gerhard Schuler,Friedrich W. Mohr +7 more
TL;DR: Good results have been achieved in the initial 50 patients, especially when considering the overall high-risk profile of these patients, and transapical minimally invasive aortic valve implantation is feasible using an off-pump technique.
Journal ArticleDOI
Aortic Valve Replacement in Octogenarians: Utility of Risk Stratification With EuroSCORE
Sergey Leontyev,Thomas Walther,Michael A. Borger,Sven Lehmann,Anne K Funkat,Ardawan Rastan,Jörg Kempfert,Volkmar Falk,Friedrich W. Mohr +8 more
TL;DR: EuroSCORE risk stratification is imprecise for prediction of perioperative mortality among octogenarian AVR patients, but may be useful for predicting mortality during medium-term follow-up.
Journal ArticleDOI
Machine learning for real-time prediction of complications in critical care: a retrospective study
Alexander Meyer,Dina Zverinski,Boris Pfahringer,Jörg Kempfert,Titus Kuehne,Simon H. Sündermann,Christof Stamm,Thomas Hofmann,Volkmar Falk,Carsten Eickhoff,Carsten Eickhoff +10 more
TL;DR: Improvements in prediction for all three investigated clinical outcomes have the potential to improve critical care and are encouraging for prospective deployment in critical care settings to direct the staff's attention towards patients who are most at risk.
