“…Previous studies have all reported varied improvement in generic QoL and/or cost in the SVT patient post-ablation 10–15. Bubien and colleagues reported improvements in their study of QoL post RFA in a mixed arrhythmia patient sample.…”

“…Their sample did not include ATACH patients, and no psychometric details of the new questionnaire or disease specific information about SVT patient symptoms were provided. Other investigators have limited their studies to only one type of SVT (AVRT or AVNRT) or used only generic questionnaires 11–15. None of these researchers used a SVT disease specific tool to measure symptoms or aspects of QoL from the patient’s perspective.…”

“…Although prior researchers have explored the effects of RFA in SVT patients,6–15 generalization of the findings from all of these studies is limited due to heterogeneous samples of different types of arrhythmia patients analyzed together; use of multiple different study specific instruments; or a lack of measurement of disease specific patient concerns. The specific concerns of patients living with SVT, their appraisal of how the symptoms affect their life, and how the RFA impacts these concerns have been overlooked in prior reports.…”

“…Qualitative and retrospective studies have explored concerns of patients specifically related to their SVT episodes 6–9. Yet published RFA outcome reports have failed to use SVT disease specific questionnaires to ascertain what distinct changes follow SVT ablation 10–15. Two published studies have measured changes in QoL after ablation from both a generic and disease specific approach in an SVT population 10,13.…”

Background It remains unclear which symptom experiences and aspects of quality of life (QoL) change after ablation in patients with supraventricular tachycardia (SVT). Objectives To determine how patient perceptions of symptoms and QoL change following ablation, we used a single group pre-postest design. Methods Patients with SVT (n=52; mean age=41 ± 17 yrs, 65% female) completed generic and disease specific measures, at baseline and one month after ablation. Results Significant improvement after ablation was noted in virtually all measures (p < 0.05). Patients reported reductions from baseline in frequency and duration of episodes, number of symptoms, and impact of SVT on routine activities. All symptoms decreased in prevalence; however, no symptoms were completely eliminated at one month follow-up. Women reported larger symptom and QoL change scores than men after ablation. Conclusions Despite the small sample, statistically significant improvement was found following ablation in a variety of symptoms and QoL indices.

“…The utilities were primarily extrapolated from the values used by Carol [8] and Larson [18] in their analysis. Larson obtained the utility retrospectively by evaluating highly symptomatic patients with SVT [18], so we considered that would be the best data for the utilities in our analysis.…”

Background Radiofrequency ablation (RFA) is an established but expensive treatment alternative for many forms supraventricular tachycardia (SVT). Currently no studies exist on the cost-effectiveness of RFA compared to medical treatment (MT) in adult Latin American population. Methods Between 2007 and 2012, we identified 103 adults who underwent RFA for SVT in the National Unit of Cardiovascular Surgery (UNICAR) in Guatemala. A decision tree was developed with all clinical outcome parameter estimates obtained from the Adult Electrophysiology Clinic. Costs were obtained from UNICAR's administration. A cost-effectiveness analysis was conducted which evaluated costs and quality adjusted life years (QALYs) to compare interventions in terms of their incremental cost-effectiveness ratios (ICERs). Results The first RFA had 83% success and cumulative 94% success was achieved with a second one. The cost of the RFA procedure itself was $5,411. RFA gains 1.46 QALYs and saves $ 7,993 compared to of MT for patients with SVT. This demonstrates that in Guatemala, RFA dominates MT in the management of SVT. Using assumptions based largely on the outcomes in UNICAR, we found that the RFA is highly cost-effective. This is a consistent finding, even after varying assumptions about efficacy, complication rates and quality of life. Conclusions RFA dominates MT by improving quality of life and reducing expenditures when used to treat severely symptomatic patients with SVT in Guatemala. The robustness of these finding to variations in parameter assumptions, suggests these findings may hold in other similar settings.
