Leaflet Pathology: Flail, degenerative (non-flail), or functional
Though the cohort of patients we evaluated were classified in our registry as DMR, 6 of the 22 patients were felt to be predominantly functional in etiology by review on TEE. MDCT classified them correctly in 4/6 cases (66%). Of the 16 cases that were analyzed as degenerative etiology, there were 7 patients with non-flail (most commonly prolapse) and 11 cases of flail pathology. MDCT correctly identified all 11 cases of flail pathology. Of the 7 non-flail cases, there were 2 cases (28.6%) that were incorrectly identified as flail pathology on MDCT (on TEE both cases were labeled as prolapse but not flail)
