[Transcatheter Aortic Valve Implantation: An Introduction and Patient Care]

Aortic stenosis has a high prevalence among individuals over 75 years of age. Transcatheter aortic valve implantation (TAVI) is a novel valve-replacement technique for patients with multiple chronic diseases who are at high risk of requiring aortic valve replacement surgery. Most of the time, the indicators of TAVI are detected during an echocardiographic exam. The femoral artery is the primary insertion site. The complications of TAVI include stroke, vascular dissection, bleeding, aortic valve regurgitation, and arrhythmia. In terms of clinical effectiveness, the mortality rate of TAVI is lower than percutaneous ballon valvuloplasty but similar to AVR. The unplanned cardiac-related re-admission rate within 30 days of discharge is lower for TAVI than for AVR. In terms of activity tolerance, TAVI is significantly better than both percutaneous ballon valvuloplasty and AVR. Comprehensive nursing care may reduce the incidence of complications associated with TAVI. Nursing care of TAVI includes explaining and providing instructions regarding TAVI prior to the procedure. After the TAVI procedure and while the patient is in the ICU, remove the endotracheal tube as soon as possible, monitor his / her neuro-cognitive status, monitor for early detection of a stroke event, record urine output to assess renal function, observe bleeding in the puncture site, and evaluate cardiac arrhythmia and pain. While in the general ward, resume early physical activities and educate the patient regarding the risks and the prevention of bleeding.
