As you mentioned, for those at risk for SAM, mainly those with myxomatous disease and prolapse, the incidence is 11%. What is of more interest and clinical challenge are those patients with outflow tract obstruction, which occurred in 34 patients, or to put it another way, in 2% of all patients in the series.
