Single-Center Experience and Short-term Outcome With the JenaValve: A Second-Generation Transapical Transcatheter Aortic Valve Implantation Device
ConclusionsThis second-generation repositionable transcatheter aortic valve implantation device could safely and successfully be implanted with a fast learning curve, significant reduction in pressure gradients, overall clinical improvement at discharge, as well as an acceptable morbidity and mortality rate in this highest-risk patient cohort.

Is Aortic Valve Repair Reproducible? Analysis of the Learning Curve for Aortic Valve Repair
Conclusions Procedural safety and efficiency improves with experience whereas efficacy is consistent over time. AV repair is reproducible and appears to have a learning curve of approximately 40-60 cases. Teaser Aortic valve repair, while effective, is performed in a limited number of centres. We examined the learning curve in two centres with programs in AV repair for safety, efficiency, and efficacy endpoints. Early mortality was ≤1% in both cohorts. Frequency of safety endpoints was reduced in both cohorts. Procedural safety and efficiency improved with experience whereas efficacy was consistent over time. AV repair i...

Surgical treatment of complex aneurysms and thoracic aortic dissections with the Frozen Elephant Trunk technique
Conclusion: Frozen Elephant Trunk is a feasible technique and should be considered. The severity of the underlying disease justifies high mortality rates. The learning curve is a reality. This approach allows treatment of more than two segments at once. Nonetheless, if a second stage is made necessary, it is facilitated. Resumo Objetivo: Relatar experiência inicial com a técnica "Frozen Elephant Trunk". Métodos: Entre julho de 2009 e outubro de 2013, 21 pacientes, 66% homens, média de idade de 56±11 anos, 66,7% portadores de dissecção da aorta tipo A de Stanford (9,6% agudas e 57,1% crônicas), tipo B (14,3%, todas ...

At UCLA, it's medicine 2.0
Tucked deep in the basement of UCLA’s Center for the Health Sciences is a room that looks more like an inventor’s fantasy workshop than the medical research facility it is. Tables are piled high with tools, electronics, prototype equipment parts and a few stray robotic arms. Posters on the wall describe pending projects in dense technical language with accompanying photos of futuristic devices. This hidden space is where scientists are working at the very forefront of technological advances in medicine. Its assemblage of smarts, parts and computers is contributing to an emerging era of personalized, tech-enabled health...

Clinical and haemodynamic outcomes in 658 patients receiving the Perceval sutureless aortic valve: early results from a prospective European multicentre study (the Cavalier Trial) ADULT CARDIAC
CONCLUSIONS The current 30-day results show that the Perceval valve is safe (favourable haemodynamic effect and low complication rate), and can be implanted with a fast and reproducible technique after a short learning period. Short cross-clamp and CPB times were achieved in both isolated and combined procedures. The Perceval valve represents a promising alternative to biological AVR, especially with a less invasive approach and in older patients.

Transient occlusion of the right coronary artery by a calcific bicuspid aortic valve mass – An interesting case of inferior STEMI
We report the case of a myocardial infarction caused by transient occlusion of the right coronary artery, secondary to a mobile calcified lesion attached to a bicuspid aortic valve. <Learning objective: The purpose of this article is to demonstrate the importance of echocardiography in patients presenting with an acute myocardial infarction, without significant coronary artery disease. Urgent echocardiography in this case ensured identification of a calcified bicuspid valve and mobile lesion that had transiently occluded the right coronary artery. Subsequent urgent surgery ensured an excellent outcome.>

Edwards Lifesciences has ‘ key events ’ around TAVR this week
Edwards Lifesciences is planning some important TAVR reveals during the PCR London Valves 2017 course that is underway. The Irvine, Calif.–based cardio devices company said yesterday that it plans to introduce the new Sapien 3 Ultra valve during the event, which runs until tomorrow. Edwards officials expect the Sapien 3 Ultra to receive CE Mark by the end of the year, with plans for a U.S. introduction in late 2018. For the Ultra, they’ve added a taller skirt to the Sapien 3 design to improve TAVR outcomes, according to the company. Edwards has incorporated the taller skirt initially with sizes 20, 23 and 26 mm. A...

Fourth mitral valve replacement in a 15-year span in a woman of childbearing age
Publication date: Available online 13 June 2018 Source:Journal of Cardiology Cases Author(s): Laura Leticia Rodríguez-Chávez, Grecia Iveth Maryelis Raymundo-Martínez, Rodrigo Gopar-Nieto There is no report of four valve replacement surgeries in a woman during 15-year follow-up. A 23-year-old female was diagnosed at 7 years with rheumatic fever. She developed severe mitral regurgitation and at the same age a prosthetic valve was placed. In the next 15 years her mitral valve was changed 3 times because of clinical, echocardiographic, and histopathologic evidence of thrombosis. Her coagulation tests all showed infratherap...

Long-standing persistent effects of atrial volume reduction combined with pulmonary vein isolation
Publication date: Available online 18 June 2018 Source:Journal of Cardiology Cases Author(s): Masami Takagaki, Naoko Ikeda, Hiroki Yamaguchi, Shinichi Mitsuyama, Tasuku Kadowaki, Tatsuya Nakao Although surgical left atrial (LA) volume reduction combined with mitral valve surgery and/or surgical ablation for atrial fibrillation has been reported to be effective, its long-term outcomes in the absence of mitral procedure are not well established. A 74-year-old man with two previous sternotomies—the first for pericardiectomy due to constrictive pericarditis and the second for mitral valve replacement with mechanical valve a...

A comparison of alternative access routes for transcatheter aortic valve implantation.
Authors: Overtchouk P, Modine T Abstract INTRODUCTION: Alternative TAVI approaches offer the possibility of valve replacement in patients ineligible to the transfemoral route. Authors provide an updated review of the existing alternative approaches. Areas covered: A systematic review of alternative approaches for TAVI was undertaken. The feasibility, safety, efficacy and technical requirements of the transapical, transaortic, transcarotid, transsubclavian and transcaval approaches have been compared. A multi-slice computed tomography is often necessary for pre-operative planning. Although the first developed, the t...
