May support selective omission of preoperative arteriography in valvular disease; leaves open need for prospective validation before practice change.
Does a clinical prognostic index accurately predict significant coronary artery disease in patients with valvular heart disease to safely omit routine preoperative coronary arteriography?
A clinical prognostic index can accurately predict significant coronary artery disease in patients with valvular heart disease, potentially reducing the need for routine preoperative coronary arteriography by up to 41% while maintaining high sensitivity.
