Chung-Ang Daegwangmyeong Hospital succeeded in zero-radiation pulse field resection for the first time in Korea
Jan 14, 2025
JoongAng University Gwangmyeong Hospital announced that it has succeeded in zero-radiation field ablation (PFA). It is even more meaningful because it was implemented for the first time in Korea.
Pulse field resection is a treatment recognized as a new medical technology in December last year, and it selectively and accurately destroys only myocardial cells that generate abnormal electrical signals that cause atrial fibrillation using high voltage electrical pulses. The medical community predicts that pulsed bowel resection will quickly become the standard treatment in the field of atrial fibrillation treatment.
It is well known to significantly reduce the risk of damage to normal tissues around the heart compared to conventional 'high frequency electrode ceramic resection' or 'cool balloon ceramic resection'. Existing procedures had the disadvantage of destroying not only target cells but also nearby normal tissues because catheters produce high or low temperatures inside the heart.
On the other hand, pulsed field resection uses a non-thermal high-voltage electric field, so there is little temperature change. Therefore, it has a great advantage of selectively destroying only the target abnormal heart cells. In addition, the procedure time was shortened because it was a method of applying hundreds of repetitive high-voltage electrical pulses within a very short period of time within a tenth of a second.
The success of pulse field resection at Chung-Ang University Gwangmyeong Hospital is more significant because it is the first in Korea to be made of 'zero radiation'. Typically, the amount of radiation exposed to a patient during a single atrial fibrillation procedure is about 15 mSv (millilibut), which is seven times the amount of natural radiation (2.4 mSv) exposed during a year. Large-scale clinical studies have shown that pulsed bowel resection had the disadvantage of having more radiation exposure than conventional treatment methods. Nevertheless, there are statistically significant side effects of the impossible and serious procedure, and it is gradually becoming a major trend of atrial fibrillation procedures.
Lim Hong-ui, a professor of circulatory technology at Chung-Ang University Gwangmyeong Hospital, succeeded in the first 'radiation zero pulse field resection' in Korea using intracardiac ultrasound to overcome these shortcomings. Five cases have been implemented so far, and the plan is to continue to expand in the future. Professor Lim Hong-ui "Pulse bowel resection not only complements the serious side effects of conventional atrial fibrillation procedures, but also proves that the radiation zero procedure can eliminate many radiation exposure doses pointed out as the only disadvantage.""It will be a good option to treat atrial fibrillation in the future " he said.
Professor Lim Hong-ui, a master of zero-radiation arrhythmia procedures, has been continuing treatment at Chung-Ang University Gwangmyeong Hospital since January this year. In the existing arrhythmia treatment (high-frequency electrode ceramic resection, cooling balloon ceramic resection), where radiation exposure was previously inevitable, more than 1,800 cases have been performed so far by applying radiation-free arrhythmia procedures using intracardiac ultrasound. It is also the only endocardial ultrasound proctor in Korea (certified guidance expert who disseminates, manages, and supervises procedures).
Professor Lim Hong-ui said, "In addition to the proliferation of pulse bowel resection, zero-radiation procedures should also be standard treatment"Our goal is to have more patients undergo safe procedures" he said.
