New Treatment of Aortic Stenosis by Transcatheter Aortic Valve Implantation - Research Paper Example

The most common of aortic stenosis undergo in patients 65 years of age and over (called senile calcific aortic stenosis) (Kulick, 2012). General symptom of aortic stenosis patients are exertional dyspnea (shorten fatigue), angina pectoris (chest pain), syncopy (fainting), and congestive heart failure. Every aortic stenosis patient will be investigated by multidisciplinary team; 2 interventional cardiologists, 1 cardiac surgeon, and an anaesthesiologist (Bedogni et al., 2011). In general, the treatment for aortic stenosis patients, who are not showing symptoms of the disease, is to take medicine while the severely symptomatic aortic stenosis patients must have surgical aortic valve replacement.

Transcatheter aortic valve implantation (TAVI) is the new procedure for severe aortic stenosis treatment. The progression of this treatment makes it suitable for patients who are inoperable or very high risk with standard surgical aortic valve replacement. In addition, the procedure of TAVI is executed in a catheterization laboratory or hybrid operating room, under general anaesthesia and without cardiopulmonary bypass (Jean-Bernard et al., 2009). The procedure of TAVI is the device implant with two transcatheter aortic valves (the Edwards SAPIEN valve, ESV or the Medtronic Corevalve, MCV) with three approaches used (transfemoral, transaxillary, or transapical) (Godino et al., 2010). The transcatheter aortic valve implantation (TAVI) was underwent with the first patient in 2002 (Rodes-Cabau, 2010).

Furthermore, TAVI clearly achieved safety and efficacy of the percutaneous treatment in aortic stenosis towards the end of 2010 (success rates > 90% and 30 days procedural mortality rates < 10%) (Rodes-Cabau, 2010). The aim of this case study will be to capture the progression of transcatheter aortic valve implantation, for patients who are inoperable or with very high surgical risk in standard aortic valve replacement. Firstly, it will briefly review the cause of aortic stenosis, followed by an explanation of transcatheter aortic valve implantation procedure with two difference transcatheter aortic valves and three difference approaches.

Finally, the major effective procedure of TAVI and future development of TAVI will be discussed. Impact of Aortic Stenosis Degenerative Aortic Stenosis is the most common valve disease, and its prevalence is projected to increase in the coming years due to aging populations. This has implications not only for those specializing in cardiovascular disease; Aortic Stenosis is increasingly diagnosed and treated by other medical specialties, including internal medicine, geriatrics and intensive care.

This point to the increasing rang of the impacts that aortic Stenosis has been established to have. The Aorta, both ascending and descending, is responsible for the circulation of oxygenates blood throughout the body. It is no wonder that the partial or complete Stenosis of the Aorta would lead to varied conditions that can be detected either in Intensive care Unit, when the patient is in a stupor, or by the gastric, as a result of ventral pooling of blood, caused by its stagnation in the veins, venules, and arterioles.

This pooling is caused by the lack of, or limited pressure from the Aorta, to help in the circulation of
