The distal ring is larger in diameter than the main shaft, and is configured to conform to an internal guidewire for insertion into the aorta, and then to deploy to form a downwardly-extending loop when in place in the left ventricle. A guidewire is received by the guidetube and is ...
- Sizing information for these TAVR valves - Guides the user through a stepped process to help choose a specific valve, then the size and lastly the important dimensions to plan a Valve in Valve procedure - Image based guidance for the ideal placement of a TAVR valve ...
It also gives information about differences between TAVR valve sizing for mitral and aortic valve in valve procedure. Mitral ring properties, which will have a big implication when considering a valve in ring procedure are also discussed. It alerts the user about potential problems especially when ...

The aim of this study was to evaluate early results of valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) versus redo surgical aortic valve replacement (SAVR) for structural valve degeneration (SVD). Background ViV TAVR has been increasingly used for SVD, but it remains unknown...
Meta-analysis comparing valve-in-valve TAVR and redo-SAVR in patients with degenerated bioprosthetic aortic valve. Catheter. Cardiovasc. Interv. 2021, 98, 940–947. [Google Scholar] [CrossRef] [PubMed] Al-Abcha, A.; Saleh, Y.; Boumegouas, M.; Prasad, R.; Herzallah, K.; Baloch, Z...
Aortic heart valve replacement for severe aortic stenosis doesn’t have to mean open heart surgery. Learn about a less invasive heart valve procedure called TAVR (transcatheter aortic valve replacement).
Indications for transcatheter aortic valve implantation (TAVI) have expanded in many countries to include patients with aortic stenosis who are at low surgical risk, and a similar expansion to this cohort is anticipated elsewhere in the world, together w
TAVR(图1)手术现在已经成为高、中危的主动脉瓣病变患者的主要治疗方法,与传统手术外科主动脉瓣置换手术(Surgical aortic valve replacemen,SAVR)相比,具有疗效高、创伤小、恢复快等优势。 图1 TAVR示意图 (一)、适应症 1.1绝对适应症: (1)重度主动脉瓣狭窄,超声心动图示跨主动脉瓣血流速度≥4m/s,或跨主动脉瓣...
