Key result
Second opinions for coronary angiography defer the procedure in ~80% of cases with low cardiac mortality.
Why the study?

Second-opinion deferral of angiography was associated with low mortality in stable CAD; hypothesis-generating and requires prospective validation before practice change.

Does a second opinion program safely reduce unnecessary coronary angiography in patients with coronary artery disease?
A second opinion can safely defer coronary angiography in a large proportion of medically stable patients with coronary artery disease.
Thomas B. Graboys (1992) conducted an observational in Coronary artery disease (n=171). Second opinion for coronary angiography was evaluated on Concordant-discordant outcome as to the second opinion, cardiac events, invasive interventions, quality of life questionnaire, and level of symptoms. A second opinion for coronary angiography resulted in deferral of the procedure in 80% of patients, with an annualized cardiac mortality of 1.1% over a mean follow-up of 46.5 months.
