The Society of Thoracic Surgeons published its newly developed short-term risk calculator of operative and thirty day risk specific to isolated mitral valve repair for primary mitral regurgitation and degenerative mitral etiology.

The calculation is based on more than preoperative variables. It takes into account age, height, weight, sex, race, Hispanic, smoker, diabetes, chronic lung disease, beta blocker, adenosine diphosphate receptor inhibitor (within 5 days), steroids, hypertension, home oxygen, cerebrovascular disease, dialysis, liver disease, IV drug abuse, alcohol (>1 drink/week), immunosuppression, hematocrit, WBC count, platelet count, creatinine (mg/dl), ejection fraction (%), cardiac reoperation, chronic heart failure, surgical priority, preoperative atrial fibrillation, tricuspid insufficiency, and predominant mitral lesion.
