About this trial
The goal of this retrospective study is to compare the long-term follow-up outcomes of pulses field ablation (PFA) Vs. radiofrequency ablation (RFA) for the patients with paroxysmal supraventricular tachycardia (PSVT). The main question to answer is:
Does the PFA was more effecient and safer that RFA for treatment of PSVT during procedure and after 1-year follow-up? Researchers will compare the acute and long-term efficiency and safety between PFA and RFA.
1. Recieved PFA or RFA 1 year ago 2. Finish the visit to the clinic at 1, 3, 6, 12 months for examinations and blood testings 3. Patients recieved PFA and PFA under propensity matched comparison according to differen variety of PSVT
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients with symptomatic PSVT including: atrioventricular nodal re-entrant tachycardia (AVNRT), atrioventricular re-entrant tachycardia (AVRT);
Age range: 18 years old ≤ age ≤ 80 years old, with no gender restriction;
Willing to receive the examinations and testings during one year follow-up required by the protocol;
Voluntary signed informed consent.
Disqualifiers
Organic heart disease;
History of cardiac surgery;
Previous failed ablation of PSVT;
Presence of any implants, such as a permanent pacemaker;
Trial population
PSVT was documented with a 12-lead surface electrocardiogram (ECG), 24-hour Holter monitoring, and esophageal electrophysiologic study (EES) before hospitalization. A diagnosis of AVNRT or AVRT was confirmed by electrophysiological study after the antiarrhythmic medications were withdrawn ≥5 half-lives. Patients with reproducibly clinical PSVT were finally enrolled.

Treatments tested in this trial
Focal Pulsed Field Ablation (PFA)
Procedure/SurgeryPatients in the PFA group underwent ablation procedures utilizing a force-sensing PFA catheter for the treatment of PSVT.
Focal Radiofrequecy Ablation (RFA)
Procedure/SurgeryPatients in the PFA group underwent ablation procedures utilizing force-sensing RFA catheters for the treatment of PSVT.
Treatment groups
Trial outcomes
Primary outcomes
Acute and long-term follow-up success rate
The Primary endpoints for efficacy included the number of subjects with acute and long-term follow-up success post ablation. The acute success was confirmed by noninducibility of clinical PSVT after programmed stimuli and drug administration after15 minutes waiting time. The long-term follow-up success was defined as the absence of clinical PSVT during the 1-year follow-up. The acute success is confirmed by catheter mapping and ECG to determine immediate ablation success rate
Incidence of intraoperative and long-term serious adverse events
The Primary endpoints for safety included the number of subjects suffering from serious adverse events. The incidence of serious adverse events related to the ablation included conduction system impairment, ventricular arrhythmia, myocardial infarction, hemolysis or major bleeding requiring transfusion, cardiac tamponade/perforation, Pericarditis requiring treatment, infectious endocarditis, valve stenosis or regurgitation deterioration, heart failure, abnormal renal and/or hepatic function, Intracerebral hemorrhage/transient ischemic attack/ stroke, and death. (Abnormal renal function (dialysis, transplant, serum creatinine \>200 mmol/L); Abnormal hepatic function (cirrhosis, bilirubin \> x 2 upper limit of normal, aspartate aminotransferase/alkaline phosphatase/alanine aminotransferase \>3 x upper limit of normal).
Secondary outcomes
Non-serious adverse events
Muscle constraction delaying the procedure, untolerable pain or cough, abnormal renal function (without dialysisserum, creatinine \<200 mmol/L), and abnormal hepatic function (cirrhosis, bilirubin \< x 2 upper limit of normal, aspartate aminotransferase/alkaline phosphatase/alanine aminotransferase \<3 x upper limit of normal.
