Background: Cardiac transplantation remains the gold standard therapy for select patients with end-stage heart failure and outcomes have improved significantly over the past few decades. We report the 5-year contemporary experience of cardiac transplantation in Western Australia, one of the most remote transplant centres worldwide.
Methods: Patients undergoing isolated cardiac transplant at Fiona Stanley Hospital (FSH) from February 2015 until April 2021 were included. Donor details were collected using donor electronic records (Donate Life, Australia). Recipient data was collated from electronic medical records at FSH and the Australia and New Zealand Society of Cardiothoracic Surgery database. The primary outcome measure was all-cause mortality. Secondary outcome measures included postoperative intensive care and total hospital length of stay and rates of acute kidney injury, rejection, serious infections, and cardiac allograft vasculopathy. Frailty indices were also assessed.
Results: A total of 60 patients were included (mean age 53±14 yrs, 66.7% male). The commonest indication for transplant was a non-ischaemic cardiomyopathy (46.7%). Mean donor age was 35±12 years and median donor ischaemia time was 171 minutes (IQR=138-240). After median follow-up of 3.7 years, there were no mortalities. Postoperative renal failure occurred in 21 (35.0%) patients, pneumonia in four (6.7%), deep sternal wound infection in three (5.1%), acute rejection in 17 (28.3%) and cardiac allograft vasculopathy (CAV) in 23 (38.3%).
Conclusion: With recipient and donor criteria comparable to national and international standards, compounded by the challenges of geographic isolation, we report the first published data on contemporary outcomes post isolated cardiac transplantation in Western Australia.
