  Purpose
This study to investigate the effects of RF ablation on left atrial systolic function in patients with atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular tachycardia (AVRT).

Condition Intervention
Paroxysmal Supraventricular Tachycardia Procedure: radiofrequency ablation

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:
A total of 100 patients with persistent,in whom successful RF ablation of slow pathway or accessory pathway was performed. Patients with atrial fibrillation, structural heart disease, ventricular arrhythmias, impaired left ventricular systolic function or on antiarrhythmics were excluded. All the patients had echocardiographic study before ablation 、1 day and 1 months after ablation.
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Study on Left Atrial Function of Paroxysmal Supraventricular Tachycardia After Radiofrequency Ablation

Primary Outcome Measures:
  • Left Atrial Function of postoperative radiofrequency ablation. [ Time Frame: 1 month ]

Estimated Enrollment: 100
Actual Study Start Date: January 1, 2017
Estimated Study Completion Date: March 1, 2019
Estimated Primary Completion Date: March 1, 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: patients with atrioventricular nodal reentrant tachycardia
radiofrequency catheter ablation therapy
Procedure: radiofrequency ablation
Experimental: patients with atrioventricular tachycardia
radiofrequency catheter ablation therapy
Procedure: radiofrequency ablation

Detailed Description:
A total of 100 patients with persistent,in whom successful RF ablation of slow pathway or accessory pathway was performed. Patients with atrial fibrillation, structural heart disease, ventricular arrhythmias, impaired left ventricular systolic function or on antiarrhythmics were excluded. All the patients had echocardiographic study before ablation 、1 day and 1 months after ablation. Left atrial systolic function was assessed using atrial ejection force (AEF) according to Manning's formula (AEF = 0.5 x ρ x MA x A(2), r: blood density = 1.06 g/cm(3), MA: mitral orifice area [cm(2)], A: A wave velocity). The following left atrial dimensions were assessed: antero-posterior (LA-AP), infero-superior (LA-IS, long axis), medio-lateral (LA-ML, short axis). The correlations between AEF and electrophysiological parameters were analysed (VA - ventriculo-atrial conduction, VA/CL - tachycardia cycle length).
