New Valve Sparing Technique
No full textThomas Modine of the Regional University Hospital of Lille in France presents a discussion and demonstration of his modified valve sparing technique for aortic valve replacement that employs the 3f Enable valve. He emphasizes the need for a technique that is easy, reproducible, and effective, and discusses the benefits of selecting his method.This presentation was originally given during the SCTS Ionescu University program at the 2019 Annual Meeting of the Society for Cardiothoracic Surgery in Great Britain and Ireland.

Blissful violence ambiguity in Stanley Kubrick's a clockwork orange
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Gradução em Letras/Ingrês e Literatura Correspondente.Analise da construção da ambigüidade na narrativa do filme Laranja Mecânica, de Stanley Kubrick (1971). Investiga a relação identificação-afastamento que o filme promove entre o protagonista e o espectador, assim como o modo peculiar como o filme trata a violência. Observa um movimento em direção à ambigüidade que se desenvolve ao longo da obra do diretor, iniciando com estruturas e personagens mais tradicionais, abandonando gradualmente as posições morais seguras. Três filmes são também discutidos como uma amostra da obra do diretor, de modo a traçar a evolução de seu estilo e sua visão de mundo: Dr. Fantástico ou Como Aprendi a Parar de me Preocupar e Amar a Bomba (1963), 2001- Uma Odisséia no Espaço (1968) e De Olhos Bem Fechados (1999)

No full textObjectives: The aim of this study was to investigate the long-term outcomes of concomitant suture bicuspidization to treat mild or moderate tricuspid regurgitation at the time of mitral valve (MV) surgery. Methods: Data from patients who underwent MV surgery for degenerative MV regurgitation with mild or moderate tricuspid regurgitation and annular dilatation between January 2009 and December 2017 were analysed. The cohort was divided into 2 groups: mitral valve surgery alone (MVA) and MV surgery with concomitant tricuspid valve (TV) repair. Results: A total of 196 patients were included in the study. MVA and MV surgery with concomitant TV repair were performed in 91 (46.4%) and 105 (53.6%) patients, respectively. Propensity score matching analysis identified 54 pairs. In the matched cohort, 30-day mortality (0.0% vs 1.9%, P = 1.0) and new permanent pacemaker implantation (11.1% vs 7.4%, P = 0.740) did not differ significantly between groups. After a mean follow-up of 6.0 (2.8) years, MV surgery with concomitant TV repair was not associated with increased mortality risk compared to MVA (hazard ratio 1.04, 95% confidence interval 0.47-2.28, P = 0.927) with 10-year overall survival rates of 69.9% and 77.2%, respectively. Furthermore, MV surgery with concomitant TV repair was associated with a significantly reduced progression of TV regurgitation (P < 0.001). Conclusions: Patients undergoing MV surgery with concomitant TV repair had similar 30-day and long-term survival, similar permanent pacemaker implantation rate and reduced progression of TV regurgitation compared to those undergoing MVA
How to Do It: Preventing LVOT Obstruction Valve-in-Valve TMVR
No full textThis article is part of CTSNet’s Guest Editor Series, 21 Years After First TAVI: Will Pace of Innovations Continue for All Heart Valves? Guest editor Gry Dahle has curated a robust collection of content that shares the knowledge, techniques, and insights of several distinguished experts from around the world.
LVOT obstruction after TMVI has very poor outcomes and is related to both a fixed obstruction—a narrowed and elongated neo-LVOT caused by the anterior mitral leaflet being pushed toward the inter ventricular septum—and a dynamic obstruction (SAM). Although the second one is more difficult to predict, the first one can be predicted through accurate preprocedural CT planning and sizing. A step-by-step approach is shown in this video.
This video demonstrates valve-in-valve transeptal transcatheter mitral valve implantation (TMVI) in a high-risk patient. The authors show a combination of all the techniques used to prevent the risk of left ventricular outflow tract (LVOT) obstruction: the septal alcohol ablation and the Lampoon technique (tip-to-base approach) with the implantation of a Sentinel device (for cerebral protection) due to the presence of a left atrial thrombus in a patient with hyperthrophic cardiomyopathy and prior aortic and mitral valve replacement.</p
Transapical TMVI: Tendyne Valve

Guest editor Gry Dahle has curated a robust collection of content that shares the knowledge, techniques, and insights of several distinguished experts from around the world.
This video shows a step-by-step approach for transapical TMVI with the Tendyne valve in an eighty-
one-year-old high surgical risk patient with severe primary mitral regurgitation and prior TAVI.
A Tendyne low-profile 29L valve was implanted and the patient recovered very well without any complications.</p
