Summary
Contact index (CI) visualization during cryoablation improves catheter-tissue contact assessment for paroxysmal supraventricular tachycardia. This method enhances lesion efficacy and patient safety by providing real-time feedback.
Area of Science:
- Electrophysiology
- Cardiovascular interventions
- Medical device technology
Background:
- Cryoablation is a common treatment for septal paroxysmal supraventricular tachycardia.
- Current cryoablation lacks real-time quantitative assessment of catheter-tissue contact.
- This limitation may affect lesion efficacy and procedural safety.
