as I understand and from my limited knowledge/ experience, TAVR is the option that has been developed to offer individuals the TAVR option of valve replacement who were deemed too unwell to undergo the conventional open chest/ open heart surgery.
FF to now, it it is now being proposed that it is likely to be the preferred option. Literature suggests that the procedure presents no greaster morbidity or mortality risk compared to SVAR, and the resources required are less for TAVR. The reduction in resources (days in hospital, days in ICU, sedation v General anaesthetic, no requirement for CP bypass, decreased recovery/ rehabilitation ) is financial, but also reduced the potential adverse events that can lead to long term complications and death. and that is indipendant of the effect of having to have ones chest split, forced open and wired close that TAVR avoids.
A win on all counts
