To Compare and Evaluate the Efficacy and Safety Between TS-RF System and BRK Transseptal Needles Used for Transseptal Puncture for Left Atrial Access.
Recruiting now · Not applicable
Conditions studied: Arrhythmias, Cardiac, Atrial Fibrillation, Heart Diseases
In brief
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.

Who can join
Age: 18 and older. Sex: any. Healthy volunteers: not accepted.
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
- = Clinical feature: Heart rhythm of less than 250 beats per minute; morphologic difference from P waves in the sinus rhythm; P waves that precede QRS waves are identifiable.
- "Ventricular Tachycardia" diagnostics = Clinical feature: Wide QRS waves appear in succession with a rapid ventricular rate of ≥ 100 beats per minute; the patients is diagnosed with persistent ventricular tachycardia if tachycardia persists for ≥ 30 seconds but with non-persistent ventricular tachycardia if not applicable.
- "Arrhythmia requiring left atrial access, including left atrial appendage occlusion, in the left atrium" diagnostics = Clinical feature: moderate or higher risk of stroke, risk of bleeding, or contraindication to anticoagulation therapy
- [Symptomatic mitral stenosis]
- "Mitral Stenosis requiring percutaneous mitral valvuloplasty through left atrial access" diagnostics
- Diagnostic criteria: confirmation of mitral stenosis with echocardiography and assessment of severity
- Symptoms: dyspnea; shortness of breath even at rest or inability to sleep in a supine position if dyspnea worsens; may accompanied by coughing, sputum, and chest pain.
- Understood this clinical study and voluntarily signed the informed consent form (ICF)1
