The New Safe Confinement was constructed 180 metres (590 ft) west of reactor 4, and slid into place. Sliding of the structure along foundation rails was a difficult process. It was pushed on Teflon pads by hydraulic pistons, and guided by lasers. [18] As of 2018, the New Safe Confinement is the world's largest movable land-based structure.
Transcatheter pulmonary valve replacement (TPVR), also known as percutaneous pulmonary valve implantation (PPVI), is the replacement of the pulmonary valve via catheterization through a vein. It is a significantly less invasive procedure in comparison to open heart surgery and is commonly used to treat conditions such as pulmonary atresia .
Percutaneous tibial nerve stimulation (PTNS), also referred to as posterior tibial nerve stimulation, is the least invasive form of neuromodulation used to treat overactive bladder (OAB) and the associated symptoms of urinary urgency, urinary frequency and urge incontinence.
Transcatheter aortic valve replacement (TAVR) is the implantation of the aortic valve of the heart through the blood vessels without actual removal of the native valve (as opposed to the aortic valve replacement by open heart surgery, surgical aortic valve replacement, AVR).
Catheter replacement of the aortic valve (called trans-aortic valve replacement or implementation [TAVR or TAVI]) is a minimally invasive option for those suffering from aortic valve stenosis. TAVR is commonly performed by guiding a catheter from the groin to the narrowed valve via the aorta using realtime x-ray technology.
It is sometimes treated with surgery, which involves rerouting blood from the right atrium into the left atrium with a patch or use of the Warden procedure. [ 9 ] [ 10 ] However, interest is increasing in catheter-based interventional approaches, as well as medical therapy for less severe cases [ citation needed ] .
Valve sparing aortic root replacement (VSARR) is an alternative procedure to the composite aortic valve graft (CAGVR, Bentall procedure). A notable benefit of VSARR is the reduced need for anticoagulation, as the patient's own aortic valve is spared and does not need to be replaced with a mechanical or bioprosthetic valve.
Pad placement for electrical cardioversion a cardiac arrhythmia may be either anterior-posterior or anterior-lateral. In an anterior-posterior setup one pad is placed on the chest and the other pad is placed on the back. In an anterior-lateral setup, one pad is placed on the chest and the other pad is placed along the left midaxillary line.
