Recently, Professor Fan Youqi from the team of Academician Wang Jian'an at the Second Affiliated Hospital of Zhejiang University successfully performed atrial fibrillation pulsed field ablation (PFA) surgeries on two patients with atrial fibrillation using the ShineyoMedical RhythPulse® Pulsed Field Ablation Catheter. These are the first batch of RhythPulse-PFA surgeries in China.The successful implementation of this surgery marks that the cardiology team of Zhejiang University Second Hospital has incorporated Pulse Field Ablation (PFA) into its routine procedures, offering a safer and more efficient new treatment option for people suffering from atrial fibrillation.
Patient Profile
Case 1
Patient, female, 75 years old, previously diagnosed with hypertension, chronic heart failure, and moderate mitral valve regurgitation, with generally fair physical condition. Admitted to the hospital due to "chest tightness and palpitations for 4 years."
Case 2
Patient, male, 62 years old, with a history of hypertension, diabetes, and generally average physical condition. Admitted to the hospital due to "detection of atrial fibrillation for over a week."
Case hosted by Professor Fan Youqi, a core member of Academician Wang Jian'an's team, discussed that: For elderly patients with multiple system diseases, the thermal energy conduction of traditional radiofrequency ablation may pose potential injury risks to adjacent esophageal mucosa, nerves, and the cardiac conduction system. After multidisciplinary evaluation and thorough communication with the patient, it was decided to adopt pulsed field ablation (PFA) technology.
Surgical Procedure
Both paroxysmal atrial fibrillation surgeries were performed under general anesthesia, utilizing pulsed ablation guided precisely by a three-dimensional mapping system. The ShineyoMedical RhythPulse catheter (20mm circular diameter for the first case, 15mm for the second) was used to achieve bilateral pulmonary vein isolation. During the procedures, pacing validation confirmed bidirectional conduction block in the pulmonary veins, indicating that the ablation targets met electrical isolation standards. The total duration of both surgeries was approximately 80 minutes, with only 20 minutes spent on manipulation and energy delivery. No other complications occurred during the procedures, and both surgeries were successfully completed.

Surgical Outcome
Case One
Case Two
[ShineyoMedical RhythPulse]®-PFA System】
ShineyoMedical's RhythPulse®-PFA system is the first approved system in China that integrates multi-channel, large focal, and targeted ablation in pulse field ablation (PFA), mainly used for treating drug-refractory and recurrent atrial fibrillation and other types of rapid arrhythmia. Its core advantages include:
Large Focal Design:Using the world's first 10mm ring ablation catheter, a single discharge can cover a lesion area with a diameter of 10mm, improving the ablation efficiency by more than three times compared to traditional technology.
Targeted Ablation Technology:Equipped with an intelligent contact detection module, it monitors the contact status between the electrode and myocardial tissue in real time, reducing the risk of hemolysis caused by ineffective discharge. Postoperative plasma free hemoglobin content decreased by 50%.
Excellent clinical validation:In a clinical trial involving 151 cases, the immediate success rate was 100%, and the success rate for atrial fibrillation treatment at 12 months post-operation reached 85.07%, achieving internationally leading standards.
