Krasnoyarsk arrhythmologists performed surgery on a patient with a donor heart for the first time

Krasnoyarsk surgeons performed radiofrequency ablation on a transplanted heart for the first time. The patient underwent an organ transplant here in 2019, but the man developed a life-threatening heart rhythm disorder. The source of arrhythmia was found in the muscle to which the donor organ was attached.

Arrhythmology surgeons at the Federal Center for Cardiovascular Surgery in Krasnoyarsk performed radiofrequency ablation on a transplanted heart for the first time. This was reported by the center’s press service.

For the first time, a patient came to the Federal Cardiac Center of Krasnoyarsk in 2019. After three heart attacks, he was diagnosed with damage to all the vessels of the heart and a catastrophic disruption of its pumping function. The only thing that could save the 48-year-old man was a donor heart transplant, which was successfully performed. The surgical treatment and early postoperative period went smoothly. The patient was discharged from the hospital on the 18th day after transplantation.

After a year and a half, the patient began to feel irregularities in the heart area, antiarrhythmic drugs were ineffective, and the specialists of the cardio center decided to perform catheter ablation of the arrhythmogenic focus. Such operations in the Krasnoyarsk center are performed without the use of fluoroscopy, which eliminates the risk of ionizing radiation on the patient’s body in general and on the transplanted heart in particular.

“After performing a high-precision 3D reconstruction of the donor heart, we established that the source of the arrhythmia is located in the area of ​​the native muscle to which the donor heart was fixed. That is, the pathological impulse spread from the patient’s own tissues (the remaining heart muscle) to the donor heart through an electrical channel that formed directly in the surgical suture,” said the arrhythmologist surgeon Evgeny Kropotkin.

He called the situation unique. Using radiofrequency ablation, the patient’s own muscle tissue was isolated from the donor tissue. 24-hour heart rate monitoring immediately after surgery showed complete elimination of the arrhythmia. The patient was discharged home and feels well.
