De Feo et al developed a score for evaluating a patient undergoing surgery for native valve infective endocarditis. The authors are from the Second University of Naples and Pineta Grande Hospital in Italy.
Patient selection: native valve infective endocarditis
Outcome: 30-day mortality
Parameters:
(1) age in years
(2) renal failure (with serum creatinine > 2 mg/dL)
(3) NYHA class
(4) ventilatory support
(5) latest pre-operative blood culture
(6) perivalvular involvement

= SUM(points for all 6 parameter)
Interpretation:
• minimum score: 0
• maximum score: 48
• The higher the score the greater the postoperative 30-day mortality.
