Definitions
Definitions of the preoperative variables align with the notes about
EuroSCORE II. Postoperative outcomes were recorded according to the
VARC-2 criteria. Surgical indications were based on recommendations of
the most recent guidelines (ACC/AHA, ESC/EACTS).
Definition of tricuspid valve regurgitation severity was based on the
absolute size of the regurgitation jet by colour flow imaging, the
relative size of the regurgitation jet ( relative to the right atrium
area ), and the hepatic venous flow pattern, as recommended by the
guidelines of the American Society of Echocardiography.
Perioperative MI has been evaluated according to the universal
definition of myocardial infarction [7].
