Abstract
Background Catheter ablation (CA) is a safe, effective, cost‐effective technique and may be considered a first‐line strategy for the treatment of symptomatic supraventricular tachycardias (SVT). Despite the high prospect of cure and the recommendations of international guidelines in considering CA as a first‐line treatment strategy, the average time between diagnosis and the procedure may be long. The present study aims to evaluate predictors related to non‐referral for CA as first‐line treatment in patients with SVT. Methods and Results The model was derived from a retrospective cohort of patients with SVT or ventricular pre‐excitation referred for CA in a tertiary center. Clinical and demographical features were used as independent variables and non‐referral for CA as first‐line treatment the dependent variable in a stepwise logistic regression analysis. Among 20 clinical‐demographic variables from 350 patients, 10 were included in initial logistic regression analysis: age, women, presence of pre‐excitation on ECG, palpitation, dyspnea and chest discomfort, number of antiarrhythmic drugs before ablation, number of concomitant symptoms, symptoms’ duration and evaluations in the emergency room due to SVT. After multivariable adjusted analysis, age (odds ratio [OR], 1.2; 95% CI 1.01–1.32; P=0.04), chest discomfort during supraventricular tachycardia (OR, 2.7; CI 1.6–4.7; P<0.001) and number of antiarrhythmic drugs before ablation (OR, 1.8; CI 1.4–2.3; P<0.001) showed a positive independent association for non‐referral for CA as SVT first‐line treatment. Conclusions The independent predictors of non‐referral for CA as first‐line treatment in our logistic regression analysis indicate the existence of biases in the decision‐making process in the referral process of patients who would benefit the most from catheter ablation. They very likely suggest a skewed medical decision‐making process leading to catheter ablation underuse.

Abstract
Introduction: Atrioventricular nodal reentrant tachycardia (AVNRT) is a common supraventricular tachycardia. Current guidelines recommend electrophysiology study (EPS) and ablation, which have been proven to show high success rates with very low complication rates. Usually, ablation of AVNRT is performed conventionally using only fluoroscopy. Electroanatomical mapping systems (EMS) are widely used in complex arrhythmias. One of their advantages is their potential in decreasing the need of fluoroscopy time (FT). In this study we analyzed patients undergoing either conventional AVNRT ablation or by using an EMS with a fluoroscopy integrating system (FIS). Materials and Methods: We included 119 patients who underwent AVNRT ablation in our study. Eighty-nine patients were ablated conventionally using only fluoroscopy, 30 patients were ablated using EMS + FIS. Results: We found that the use of EMS + FIS led to a significant reduction of FT (449.90 ± 217.21 vs. 136.93 ± 109.28 sec., p < 0.001) and dose-area-product (DAP, 268.27 ± 265.20 vs. 41.07 ± 27.89 μGym2, p < 0.001) without affecting the procedure time (PT, 66.55 ± 13.3 vs. 67.33 ± 13.81 min, p = 0.783). Furthermore, we found no significance with regard to complications. Conclusion: The use of EMS+FIS is safe and feasible. It leads to a significant reduction of both FT and DAP without affecting PT and safety. Hence, EMS + FIS is beneficial for both the operator and the patients by reducing the radiation exposure.

Abstract
BACKGROUND Catheter ablation is considered the first-line treatment of symptomatic atrioventricular nodal reentrant tachycardia (AVNRT). It has been associated with a risk of heart block (HB) requiring a pacemaker. This study aims to determine potential clinical predictors of complete heart block as a result AVNRT ablation. METHODS Consecutive patients undergoing catheter ablation for AVNRT from January 2001 to June 2019 at two tertiary hospitals were included. We defined ablation-related HB as the unscheduled implantation of pacemaker within a month of the index procedure. Use of electroanatomic mapping (EAM), operator experience, inpatient status, age, sex, fluoroscopy time, baseline PR interval, and baseline HV interval was included in univariate and multivariate models to predict HB post ablation. RESULTS In 1708 patients (56.4 ± 17.0 years, 61% females), acute procedural success was 97.1%. The overall incidence of HB was 1.3%. Multivariate analysis showed that age more than 70 (odds ratio [OR] 7.907, p ≤ .001, confidence interval [CI] 2.759-22.666), baseline PR ≥ 190 ms (OR 2.867, p = .026, CI 1.135-7.239) and no use of EAM (OR 0.306, p = .037, CI 0.101-0.032) were independent predictors of HB. CONCLUSION Although the incidence of HB post AVNRT ablation is generally low, patients can be further stratified using three simple predictors.

Abstract
Background Multiple studies have demonstrated the importance of adequate catheter–tissue contact in the creation of effective lesions during radiofrequency catheter ablation. The development of contact force (CF)-sensing catheters has contributed significantly to improve clinical outcomes in atrial fibrillation. However, CF-sensing technology is not used in the ablation of paroxysmal supraventricular tachycardia (PSVT). The possible reason for this is that PSVT ablation with the conventional approach (i.e. nonirrigated, non-CF-sensing catheters) is considered a relatively low-risk procedure with fairly high success rates (short and long term). The aim of this study is to determine whether CF sensing can further improve the outcomes of PSVT ablation. Methods/design The COBRA-PATH study is a single-center, two-armed, randomized controlled trial. Patients without structural heart disease being referred for electrophysiology study, because of PSVT and potential treatment with radiofrequency (RF) catheter ablation, will be randomly assigned to either manual ablation with standard nonirrigated ablation catheters or manual ablation with an open-irrigated ablation catheter equipped with CF sensing (used in a virtual nonirrigated modus). The primary study endpoint is the difference in the number of RF applications during the ablation of atrioventricular nodal re-entry tachycardia, and that of Wolff–Parkinson–White syndrome and atrioventricular re-entrant tachycardia. Secondary outcome parameters include acute and long-term procedural success rates, overall duration of RF applications, procedure/fluoroscopy durations and safety parameters. Discussion We expect to see a reduced number/duration of RF applications required to achieve effective lesion creation, and consequently a decrease in total procedure/fluoroscopy times. Although a significant improvement in procedural success rates (acute/long term) might not be feasible to demonstrate (given the relatively high success rate of the standard ablation method), the possible decrease in procedure duration and the consequential reduction of radiation exposure has important clinical implications for both operators and patients undergoing the procedure.

Cost-Effectiveness of Radiofrequency Ablation for Supraventricular Tachycardia in Guatemala: Patient outcomes and economic analysis from a low-middle-income country.

Abstract
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.

Abstract
BACKGROUND Radiofrequency ablation (RFA) is undertaken as a potentially curative treatment for a variety of heart rhythm disturbances. Previous studies have demonstrated improved quality of life and reduced symptoms after ablation. In many health care environments waiting lists exist for scheduling of procedures. However, the psychological effects of waiting for radiofrequency ablation have not previously been assessed. We hypothesized that waiting for this intervention may be associated with increased psychological morbidity and health care costs. METHODS Ninety-two patients scheduled for elective RFA completed repeated questionnaires comprising the Medical Outcomes Short Form 36, Hospital Anxiety and Depression Scale, and an in-house questionnaire designed to assess the burden of symptoms related to arrhythmia (arrhythmia-related burden score). Mean scores were generated and compared at time points while waiting, before and after the procedure. Regression analyses were carried out to identify predictors of increased psychological morbidity while waiting and immediately prior to the procedure. Health care costs during the waiting period as a consequence of arrhythmia were quantified. RESULTS Mean scores for parameters of psychological morbidity worsened during the period of waiting and improved after the procedure. Predictors of adverse effects within the cohort varied according to the time point assessed for each of the measures of psychological morbidity. A conservative estimate of the health care cost incurred while waiting exceeds £ 181 per patient. CONCLUSIONS Waiting for radiofrequency ablation appears to be associated with adverse psychological effects and health care costs. These results may support strategies to reduce waiting times and prioritize resource allocation.

Abstract
OBJECTIVES It remains unclear which symptom experiences and aspects of quality of life (QOL) change after ablation in patients with supraventricular tachycardia (SVT). To determine how patient perceptions of symptoms and QOL change after ablation, we used a single group pretest-posttest design. METHODS Patients with SVT (n=52; mean age 41+/-17 years; 65% female) completed generic and disease-specific measures at baseline and 1 month after ablation. RESULTS Significant improvement after ablation was noted on virtually all measures (P <.05). Patients reported decreases from baseline regarding 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 1-month follow-up. Women, more so than men, reported larger changes in symptom and QOL scores after ablation. CONCLUSIONS Despite the small sample, statistically significant improvement was found after ablation in a variety of patients with different symptoms and QOL indices.

Abstract
BACKGROUND Atrioventricular nodal reentrant tachycardia (AVNRT) is probably the most common form of paroxysmal supraventricular tachycardia. Percutaneous catheter ablation is a technique to interrupt cardiac conduction pathways selectively. The anesthetist is challenged to provide a safe anesthetic which takes into account the electrophysiologist's requirements for minimal cardiac conduction interference. Propofol is an ideal drug. However, previous studies have shown that the infusion of propofol has sometimes been associated with bradyarrhythmias or conversion of arrhythmias to sinusal rhythm. The purpose of this report is to verify the interferences of propofol in the electrophysiological properties of the atrioventricular (AV) node conduction system in patients with AVNRT. METHODS Patients were randomly assigned to receive either a placebo or propofol at sedative doses. An electrophysiological study was performed consisting of measuring the anterograde (AERPFP) and retrograde effective refractory period of the fast (RERPFP) and the anterograde effective refractory period of the slow (AERPSP) AV nodal pathway. Reciprocating tachycardia was induced and the cycle length (CL) and atrial-His (AH), His-ventricular (HV), and ventriculoatrial (VA) intervals were measured. RESULTS Propofol did not cause alteration (P > 0.05) in the AERPFP or RERPFP and the AERPSP AV nodal pathway. The AH, HV, and VA intervals were not affected. Sustained reciprocating tachycardia could be induced in the all patients. All slow pathways were successfully identified and ablated. CONCLUSION Propofol has no effect on the electrophysiological properties of the AV node conduction system. It is thus a suitable anesthetic agent for use in patients undergoing ablative procedures.
