NCT06358391

Brief Summary

The purpose of this study is to compare and assess efficacy and safety between the study device "TS-RF system consisting of a electrosurgical system, general-purpose (TS-RF Generator) and a electrosurgical system electrode, hand-controlled, general-purpose, single-use (TS-RF Needle)" and the control device "needle, puncture, single-use (BRK Transseptal needle)", both of which are used for the transseptal puncture performed to enable left atrial access for the treatment of symptomatic arrhythmia and mitral stenosis and then to demonstrate that the study device is non-inferior to the control device.

Outcome Measures

Primary Outcomes (1)

  • First-pass TSP Success Rate (percent)

    Probability that the needle crosses from the superior vena cava to the fossa ovalis and its left atrial access is identified at a time by fluoroscopy, transesophageal echocardiography (TEE), or intracardiac echocardiography (ICE).

    Day of procedure

Secondary Outcomes (6)

  • TSP Time (Second)

    Day of procedure

  • Fluoroscopy Time (Second) for TSP

    Day of procedure

  • Needle cross-over between the study and control groups

    Day of procedure

  • Intra-TSP procedural device-associated complications

    Day of procedure

  • Changes in patient's quality of life

    before the procedure (baseline) and at 2 weeks after the procedure.

  • +1 more secondary outcomes

Other Outcomes (2)

  • Intra-TSP procedural Adverse Events

    During procedure

  • Overall Adverse Events

    for 2 weeks after the procedure

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • ≥ 18 years of age
  • Diagnosed with one of the following cardiac disorders as shown in the medical record:
  • \[Symptomatic arrhythmia\]
  • "Atrial fibrillation" diagnostics (including paroxysmal, persistent, long-standing persistent and permanent atrial fibrillation)
  • Diagnostic criteria: atrial fibrillation lasting ≥ 30 seconds as a result of standard 12-lead electrocardiogram (ECG) or single-lead ECG
  • ECG feature: irregular R-R interval, lack of visible P waves, irregular atrial activation
  • Symptoms: fatigue, palpitation, dyspnea, chest discomfort, sleep disorders, mental stress
  • Type:
  • Paroxysmal atrial fibrillation (stopping within 48 hours without any treatment; restoring the sinus rhythm with cardioversion within 7 days)
  • Persistent atrial fibrillation (persisting for ≥ 7 days; including sinus rhythm restoration with direct-current cardioversion (DCC) or pharmacological cardioversion after the persistence)
  • Long-standing persistent atrial fibrillation (persisting for ≥ 1 year; including cases requiring cardioversion)
  • Permanent atrial fibrillation (The patient and healthcare provider accept atrial fibrillation and do not consider cardioversion; if cardioversion is considered, the atrial fibrillation is reclassified as long-standing persistent atrial fibrillation)
  • "Paroxysmal Supraventricular Tachycardia" diagnostics
  • = Clinical feature: The heart beats regularly 150 to 200 times per minute; the start and end of paroxysmal supraventricular tachycardia are clearly recognizable; these occur unexpectedly and stop abruptly.
  • "Ectopic Atrial Rhythm Tachycardia" diagnostics
  • +8 more criteria

You may not qualify if:

  • \[For symptomatic arrhythmia and mitral stenosis\] If any of the following applies, you cannot participate in this clinical trial.1,26,37,45,46
  • Patients with significant congenital heart defects, such as atrial septal defect or pulmonary vein (PV) abnormalities (excluding patent foramen ovale (PFO)).
  • Thrombus in the left atrium
  • Atrial fibrillation to reversible causes (e.g. hyperthyroidism, thoracic surgery)
  • Known or suspected left atrial myxoma.
  • Unstable angina.
  • Pre-existing hemidiaphragmatic paralysis
  • Contraindication to anticoagulation or radiocontrast materials
  • liver disease (including active hepatitis) and kidney disease.
  • Cerebral ischemic event (strokes or TIAs) during the six-month interval preceding the consent date
  • Malignant tumors or hematological diseases or life expectancy of less than one (1) year.
  • Currently participating or anticipated to participate in any other clinical trial of a drug, device or biologic that has the potential to interfere with the results of this study
  • Unwilling or unable to comply fully with study procedures and follow-up
  • A pregnant woman, a woman planning on becoming pregnant, or a lactating woman.
  • Ineligible for study participation in the judgment of the investigator.
