Improving outcomes in Tavi: A multidisciplinary team approach to high risk cases
Abstract
Aortic stenosis
is one of the most common valvular heart diseases worldwide. The most common cause of aortic stenosis
being attributed to a degenerative and calcified aortic valve rather than
rheumatic origin. Eventhough, surgical aortic valve interventions are indicated
in patients with severe aortic stenosis, TAVI (Transcatheter Aortic Valve
Implantation) has been recommended for those patients at high risk for surgery
with multiple co-morbidities and for whom surgery is contraindicated. After the
firstever ground-breaking success of
TAVI in 2002 by Alain Cribrier and his colleagues in a 57 year old man with
severe aortic stenosis in cardiogenic shock with multiple co-morbidities, the indications of
TAVI have expanded from surgically high risk to intermediate and low risk
patients. Also, with gaining experiences and popularity with TAVI, the
challenges faced with each patient is different either from anatomical point of
view and the associated co-morbidities or the technical perspective . With wide
acceptance of TAVI we have come a long way not only in bringing out the expanded indications but also with the wide
range of technological developments and adjustments to suit the native valve. From balloon
expandable valves to self expanding TAVI valves, improving valve designs with
additional sealing skirts to reduce the paravalvular leak, higher implants to
reduce conduction disorders, and improved delivery systems by using small
catheter size, TAVI is considered non inferior to SAVR with promising results.
This study aims to discuss about the challenges faced during TAVI procedure
over the last 10 years in a private hospital, South India.
