Severe aortic stenosis (AS) is the most common form of valvular heart disease in the developed world with a rising prevalence due to an ageing Australian population. Transcatheter aortic valve implantation (TAVI) offers a less invasive option for the treatment of severe AS with evidence supporting of TAVI compared to medical therapy in inoperable patients, and superior to surgical aortic valve replacement (SAVR) in high-risk patients. Equal outcomes have been observed in all-comer intermediate risk populations. The Heart Team utilises a shared decision-making approach between physicians and surgeons in risk stratifying patients and reduces the intrinsic bias that may occur if decisions are made in isolation. Geriatric assessment is useful in identifying pre-operative frailty, a major risk factor for death post aortic valve intervention. In severe AS, a decision can be made collaboratively to pursue TAVI, SAVR, a Ross Procedure, or conservative management. The learning curve associated with TAVI has improved markedly with overall complication rates decreasing around the world. Contemporary changes in practice such as conscious sedation without general anaesthesia, expedited recovery and early discharge will likely improve cost-effectiveness. In 2018, TAVI is a well-established procedure in Australia that has revolutionised the management of severe AS. In the future with an expanding elderly population, the number of patients to benefit from transcatheter therapies for severe AS is hypothesised to increase 4-10 fold. Heart Team assessment is crucial in patients with severe AS to direct appropriate management. This article is protected by copyright. All rights reserved.
