Donor hearts from individuals who had been COVID-19-positive seemed to be as protected for transplantation as these from folks with out COVID-19, in keeping with a short-term evaluation to be offered on the American Heart Association’s Scientific Sessions 2022. The assembly, held in individual in Chicago and nearly, Nov. 5-7, 2022, is a premier world alternate of the newest scientific developments, analysis and evidence-based scientific apply updates in cardiovascular science.
The evaluation contains information from the primary 84 COVID-positive donor coronary heart transplant recipients within the U.S.
These findings counsel that we might be able to be extra aggressive about accepting donors which can be constructive for COVID-19 when sufferers are in dire want of an organ for coronary heart transplantation.”

The 2022 American Heart Association/American College of Cardiology/Heart Failure Society of America tips for managing coronary heart failure advocate coronary heart transplantation for individuals who progress to superior (stage D) coronary heart failure. People with stage D coronary heart failure have extreme signs, reminiscent of shortness of breath, fatigue and swelling, that intrude with each day life and will result in recurrent hospitalizations regardless of receiving optimum medical therapies.
Demand for coronary heart transplants has doubled previously 30 years – from 1,676 coronary heart transplantations reported within the U.S. in 1988 to three,658 recipients in 2020 in keeping with the American Heart Association’s Heart Disease and Stroke Statistics – 2022. The United Network for Organ Sharing experiences greater than 3,400 folks within the U.S. are ready for a coronary heart right this moment.
“Despite the elevated want for this operation, there’s a continued scarcity of obtainable donor organs for folks in want of transplantation. The COVID-19 pandemic made issues worse with an elevated charge of donors testing constructive for COVID-19, which usually renders the donors unsuitable for transplantation,” Kim stated. “However, a number of educational facilities have began to make use of COVID-19-positive donor hearts for coronary heart transplantation in latest months and have reported good outcomes.”
Researchers on this examine analyzed the United Network for Organ Sharing database for all grownup coronary heart transplants within the U.S. from February 2021 to March 2022, which included the primary 84 COVID-19-positive donor coronary heart transplants amongst 3,289 whole coronary heart transplants. They in contrast outcomes as much as 30 days after transplantation between sufferers who acquired hearts from COVID-19-positive donors to those that acquired hearts from COVID-19-negative donors. The researchers assessed charges of demise within the hospital or inside 30 days after the operation, post-operative problems, and demise from particular causes, reminiscent of infections and lung problems, that are recognized considerations for individuals who have had COVID-19.
The evaluation discovered the variations in transplant outcomes between teams weren’t statistically vital. They discovered:
- Both teams of donor organ recipients had comparable charges of demise within the hospital and at 30 days after transplantation, in addition to comparable charges of problems reminiscent of graft failure (a situation the place the physique rejects the brand new organ) and lung problems.
- The common hospital keep for these receiving a COVID-19-positive donor coronary heart was 15 days, versus 17 days for sufferers receiving a coronary heart from a donor with out COVID-19;
- Organ rejection occurred in 2.4% of the recipients from COVID-19-positive donors, in comparison with 1% of the others;
- 96.1% of people that acquired hearts from COVID-19 constructive donors survived the primary 30 days in comparison with 97% of those that acquired hearts from donors with out the virus.
- Among the 4 sufferers who died after receiving a coronary heart from a COVID-19-positive donor, none died from respiratory causes or infections.
The researchers stated they had been stunned by the findings. “Specifically, we thought demise from respiratory or lung-related causes can be an issue amongst recipients receiving donor hearts with COVID-19,” Kim stated. “Yet, we discovered no such variations, and actually, this examine presents early proof that COVID-19-positive donor hearts could also be as protected as hearts with out COVID-19 for coronary heart transplantation.”
“These findings present proof that outcomes had been comparable at 30-days post-transplant amongst sufferers who acquired COVID-19-positive donor hearts, so the potential dangers look like decrease than anticipated,” stated Eldrin F. Lewis, M.D., M.P.H., FAHA, chair of the Association’s Scientific Publishing Committee, an advance coronary heart failure and coronary heart transplant specialist, and the Simon H. Stertzer M.D. Professor of Cardiovascular Medicine and chair of the division of cardiovascular medication at Stanford University. “In flip, this will assist to deal with the shortages in donor hearts for transplantation and scale back ready instances, since folks typically get sicker as coronary heart failure progresses whereas ready for a donor coronary heart to turn out to be accessible.”
The examine’s affect is proscribed by its small pattern dimension, and the evaluation could also be underpowered to detect variations in coronary heart transplantation experiences. Longer-term research are wanted to evaluate how sufferers receiving hearts from COVID-19-positive donors fare past 30 days after surgical procedure and the speed to early graft failure.
