Patients' Perspective on Radiofrequency Catheter Ablation of AVRT and AVNRT (PPRA)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01594814

Brief Summary:

Atrioventricular nodal reciprocating tachycardia (AVNRT) and atrioventricular reciprocating tachycardia (AVRT) are two similar supraventricular re-entry tachycardias (SVT) emerging in relatively young age in patients without apparent structural heart disease or significant comorbidities. The treatment of choice in those patients is radiofrequency ablation (RFA).

The PPRA study is a prospective observational study developed to thoroughly analyze quality of life, utility and willingness-to-pay of Polish patients undergoing RF ablation of AVNRT or AVRT.

Based on collected data the investigators will prepare a profile of patient who will benefit most from radiofrequency ablation and who should be scheduled in first place for the ablation in case of problems with accessibility to this service.

What is more an analysis of medical and indirect costs of care will be performed.

Study Type : Observational
Actual Enrollment : 82 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Patients' Perspective on Radiofrequency Catheter Ablation of AVRT and AVNRT - a Quality of Life, Utility and Willingness to Pay Study (PPRA Study)
Study Start Date : January 2012
Actual Primary Completion Date : November 2014
Actual Study Completion Date : November 2014

Group/Cohort Intervention/treatment
RFA of AVNRT of AVRT Procedure: RFA
radiofrequency ablation of slow pathway or accesory pathway

Primary Outcome Measures :
  1. Health-related quality of life (HRQOL) [ Time Frame: two months ]
    Mean score of Patient Perception of Arrhythmia Questionnaire (PPAQ) - a disease-specific QoL questionnaire for patients suffering from supraventricular tachycardia translated and validated according to ISPOR (International Society For Pharmacoeconomics and Outcomes Research) guidelines

Secondary Outcome Measures :
  1. Utility of health state [ Time Frame: two months ]
    Mean score of EQ-5D - a generic questionnaire measuring a health state utility (official Polish translation)

  2. Medical and indirect cost [ Time Frame: one year ]
    Cross-sectional data gathered using original questionnaire designed to measure medical and indiresct costs related to arrhythmia incurred during a year preceding RFA

  3. Willingness-to-pay [ Time Frame: one day ]
    a cross-sectional willingness-to-pay questionnaire studying hypothetical situation where RFA was not financed by Polish Health Fund

  4. Effectiveness [ Time Frame: two days ]
    Data on medical history, final diagnosis, outcome of treatment, safety and future recommendations
