Echocardiography in Transcatheter Aortic Valve Implantation and Mitral Valve Clip
Transcatheter aortic valve implantation and transcatheter mitral valve repair (MitraClip) procedures have been performed worldwide. In this paper, we review the use of two-dimensional and three-dimensional transesophageal echo for guiding transcatheter aortic valve replacement and mitral valve repair.
متن کاملEarly partial clip detachment following transcatheter mitral valve repair.
A 71-year-old man with a history of dyspnoea in New York Heart Association functional class III, due to heart failure and severe mitral regurgitation, was admitted to hospital for the treatment of valvular heart disease. The patient, diagnosed with type 2 diabetes in the past, had undergone two coronary artery bypass surgeries (in 1998 and 2014), the latter complicated by periprocedural myocard...
متن کاملAutomatic non-rebreathing valve.
EFFICIENT ventilation of the anaesthetized patient, without carbon dioxide absorption, can be carried out using the valve to be described. It is simple, reliable, efficient and silent. In figure 1 A and E are low resistance valves. P, and P2 form a bypass opening into the balloon B, which lies free in the exit tube X. The balloon is made of very thin rubber and is of such a size that when infla...
متن کاملExperimental values for adjusting an automatic control valve in gas pipeline transportation
When a natural gas pipeline ruptures, the adjacent automatic line control valves (ALCVs) should close quickly to prevent leakage or explosion. The differential pressure set point (DPS) at each valve location is the main criteria for value setting in ALCV action. If the DPS is not properly adjusted, the ALCV may mistakenly close or it may not take any action at proper time. This study focused on...
متن کاملThe Comparative Study of Microsurgical Cerebral Aneurysm Clip Implants; Titanium Clip vs. Stainless Steel Clip
OBJECTIVE To perform a comparative study between two groups of populations, titanium (T) group versus stainless steel (S) group, who were clipped with titanium and stainless steel materials, respectively, the incidence of regrowth from the original aneurysms, the clip slippage, and post-clipping seizure attack were analyzed. The patients were followed more than 5 years after microsurgical cereb...
