Of 333 patients transplanted within the study period, 1 incorrectly classified lung only transplant patient was excluded. Also excluded were 14 patients transplanted at a center other than Duke University Medical Center (DUMC) and 5 patients who received a second or third heart transplant. Of the 313 evaluable patients, 204 did not receive TPE within the study period (Zero TPE cohort) and 109 did. Of these 109 TPE-treated patients, 82 received TPE within 24 hours of transplantation with 40 patients receiving a single TPE procedure (Single TPE cohort) and 42 patients receiving multiple TPE procedures (Multiple TPE cohort); An additional 27 patients received one or more TPE procedures beginning more than 24 hours post transplantation (Delayed TPE cohort).
