Values are expressed as median with first and third quartiles (Q1–Q3) or n (%) unless otherwise indicated. PH: pulmonary hypertension; NYHA: New York Heart Association. #: more than one reason for inoperability is possible. ¶: totals exceed 100% since it is possible to record more than one ethnicity. “Caucasian/white” and “Asian” was recorded for one patient in Europe, two patients in Japan and one patient in America and others.
