Transcatheter Versus Surgical Aortic Valve Replacement in Patients With Severe Aortic Valve Stenosis: 1-Year Results From the All-Comers NOTION Randomized Clinical Trial
Hans Gustav Hørsted Thyregod,Daniel A Steinbrüchel,Nikolaj Ihlemann,Henrik Nissen,Bo Juel Kjeldsen,Petur Petursson,Yanping Chang,Olaf Walter Franzen,Thomas Engstrøm,Peter Clemmensen,Peter Bo Hansen,Lars Willy Andersen,Peter Skov Olsen,Lars Søndergaard +13 more
TL;DR: No significant difference between TAVR and SAVR was found for the composite rate of death from any cause, stroke, or myocardial infarction after 1 year in the NOTION trial.
Journal ArticleDOI
Five-Year Clinical and Echocardiographic Outcomes from the Nordic Aortic Valve Intervention (NOTION) Randomized Clinical Trial in Lower Surgical Risk Patients
Hans Gustav Hørsted Thyregod,Nikolaj Ihlemann,Troels H. Jørgensen,Henrik Nissen,Bo Juel Kjeldsen,Petur Petursson,Yanping Chang,Olaf Walter Franzen,Thomas Engstrøm,Peter Clemmensen,Peter Bo Hansen,Lars Willy Andersen,Daniel A Steinbrüchel,Peter Skov Olsen,Lars Søndergaard +14 more
TL;DR: The NOTION trial (Nordic Aortic Valve Intervention) was designed to compare transcatheter aortic valve replacement (TAVR) with surgical aorta replacement (SAVR) in patients ≥70 years old.
Journal ArticleDOI
Two-Year Outcomes in Patients With Severe Aortic Valve Stenosis Randomized to Transcatheter Versus Surgical Aortic Valve Replacement The All-Comers Nordic Aortic Valve Intervention Randomized Clinical Trial
Lars Søndergaard,Daniel A Steinbrüchel,Nikolaj Ihlemann,Henrik Nissen,Bo Juel Kjeldsen,Petur Petursson,Anh Thuc Ngo,Niels Thue Olsen,Yanping Chang,Olaf Walter Franzen,Thomas Engstrøm,Peter Clemmensen,Peter Skov Olsen,Hans Gustav Hørsted Thyregod +13 more
TL;DR: Two-year results from the NOTION trial demonstrate the continuing safety and effectiveness of TAVR in lower-risk patients, and long-term data are needed to verify the durability of this procedure in this patient population.
Journal ArticleDOI
The Nordic aortic valve intervention (NOTION) trial comparing transcatheter versus surgical valve implantation: study protocol for a randomised controlled trial.
Hans Gustav Hørsted Thyregod,Lars Søndergaard,Nikolaj Ihlemann,Olaf Walter Franzen,Lars Willy Andersen,Peter Bo Hansen,Peter Skov Olsen,Henrik Nissen,Per Winkel,Christian Gluud,Daniel A Steinbrüchel +10 more
TL;DR: This randomised clinical trial will evaluate the benefits and risks of TAVI using the transarterial CoreValve System compared with SAVR in patients with severe degenerative AV stenosis to influence the choice of treatment modality.
Journal Article

Nikolaj Ihlemann,Olaf Walter Franzen,Erik Jørgensen,Peter Bo Hansen,Christian Hassager,Jacob E. Møller,Lars Søndergaard +6 more
TL;DR: Percutaneous mitral valve repair with the MitraClip system is a reasonable alternative in patients with MR and a high estimated surgery risk and is now available in Denmark.
