    Esophageal Temperature Monitoring During Radiofrequency Ablation of Atrial Fibrillation (2005)

    Notes: Introduction: Ablative strategies for atrial fibrillation have centered on the left atrium, in particular the pulmonary veins. An emphasis on ablating outside the ostia of the pulmonary veins appears to have reduced the risk of pulmonary vein stenosis. Unfortunately, ablation in the posterior left atrium has been reported to result in fatal atrio-esophageal fistula. Methods and Results: We monitored esophageal temperatures in 16 consecutive patients undergoing atrial fibrillation ablation. There were 14 men and 2 women; average age 54.7 ± 10.6 years. Eight patients had a lasso-guided pulmonary isolation procedure, eight an electroanatomically guided left-atrial circumferential approach. A commercially available esophageal temperature probe (Mallinckrodt Mon-a-therm 12F Esophageal Stethoscope with Temperature Sensor, Thermistor 400 Series) was positioned under general anesthesia. Temperature changes were noted and related to the relative location of the ablation catheter and the temperature probe during the temperature change. The esophagus was midline in three, right sided in three, and left sided in the remaining patients. Temperature rises could be recorded at the posterior aspect of any pulmonary vein. Detailed analysis of six patient maps revealed heating occurred with lesions created within 1 cm of the esophagus. Conclusion: The location of the esophagus relative to the back of the left atrium displays considerable variability. It is rarely midline and most often lies in close proximity to the left-sided veins. Ablation in close radiographic proximity (approximately 1 cm) to the esophagus as defined by a radio-opaque temperature probe can result in heating at the esophageal lumen.

    Notes: Accessory pathways are typically located along the left or right atrioventricular junction. Distinct ventricular pre-excitation patterns determined by surface electrocardiography can provide reasonable pathway localization prior to invasive mapping and catheter ablation. We report an accessory pathway producing an unusual electrocardiographic appearance suggestive of ventricular outflow region pre-excitation. Pacing maneuvers and standard intracardiac recordings confirmed an atrial insertion immediately adjacent to the atrioventricular (AV) node and supported a ventricular insertion at the outflow tract region well away from the AV junction. The elimination of pathway conduction was achieved with radiofrequency (RF) energy at the atrial insertion after successful ice mapping excluded AV block at the target site. This is the second such pathway observed at our institution over a 20-year period.

    Isolation of Pulmonary Veins Using a Transvenous Curvilinear Cryoablation Catheter: Feasibility, Initial Experience, and Analysis of Recurrences (2005)

    Notes: Introduction: Pulmonary vein isolation (PVI) using focal cryothermal catheters is safe and moderately effective, but associated with long procedure times. We hypothesized that a linear freezing segment could shorten fluoroscopic and procedure times. We report our initial experience with a novel circular cryothermal catheter. Methods and Results: Complete PV isolation (PVI) was achieved in 41 of 45 PVs by cryoablation (91%) in 18 patients who underwent Lasso-guided cryothermal using a novel 7 F circular catheter (2.5 ± 0.7 veins per patient). A mean of 27.2 ± 11 applications per patient (9.2 ± 4.7 per vein) with a mean temperature −79.8 ± 4°C were delivered. Recorded temperatures did not predict complete or incomplete isolation. Focal cryothermal ablation using a 7 F 4-mm tip was required in the remainder for isolation. During 14.8 ± 6.2 month follow-up, 4 (22%) had no recurrence of AF, and 7/18 (39%) had 〉90% reduction in symptoms without antiarrhythmic agents (AAA). Computed tomography scans at 3 months showed no stenosis (14.1 ± 2.5 mm, 13.9 ± 2.4 mm; P = 0.2). Eight patients underwent repeat ablation. Mapping demonstrated 13 of 14 (93%) previously isolated veins had recovery of over 64 ± 24% of the ostium. All were successfully isolated with RF and 7 of 8 were arrhythmia free 6.0 ± 2.9 months after ablation. Overall, 14 of 18 (78%) patients had their arrhythmia clinically controlled without drugs after one or two procedures. Conclusions: Our initial experience demonstrates safety and feasibility of circular cryothermal ablation with less fluoroscopic and procedure times as compared to focal cryothermy. As with RF, complete and permanent isolation of the PVs is not easily achieved. Reducing heat load due to PV flow may improve results.

    Atrial Response to Ventricular Antitachycardia Pacing Discriminates Mechanism of 1:1 Atrioventricular Tachycardia (2005)

    Notes: Background: Inappropriate shocks from implantable cardioverter defibrillators (ICD) remain a significant clinical problem despite device discrimination algorithms. The atrial response to antitachycardia pacing (ATP) may determine the mechanism of 1:1 A:V tachycardia. Methods: For this study we refer to sinus tachycardia, atrial tachycardia (AT), atrial fibrillation, and flutter as atrial tachycardia (AT), and all other tachycardia as “non-AT.” Three atrial response patterns during the burst of ATP were determined. The atrial cycle length (ACL) may be unchanged (type 1) indicating AT. The ACL may show variation during ATP (type 2) indicating variable VA block and does not discriminate between an AT and a non-AT mechanism, in which case a default diagnosis of non-AT is made. The ACL may accelerate to the ATP cycle length (type 3) indicating entrainment. A VAAV response at the end of ATP was considered diagnostic of AT (type 3A) whereas a VAV or VVA response was considered a non-AT mechanism (type 3B). This algorithm was applied to ICD tracings from 68 episodes of spontaneous 1:1 A:V tachycardia that had 136 sequences of ATP administered. The rhythm “truth” was determined by consensus of two experienced clinicians. Results: The algorithm correctly identified AT with a sensitivity of 71.9% (95% CI: 67.1–73.6), and specificity of 95% (83.5–99.1). The PPV was 97.2% (90.9–99.5), and NPV 58.5% (51.4–61.0). Kappa was 0.57 (0.43–0.62). If used clinically the algorithm would have aborted 53.3% (8/15) of inappropriate shocks delivered into an AT-mechanism tachycardia and would not have withheld a shock for any episode of VT. Conclusion: Analysis of atrial response patterns during and after ventricular ATP can successfully discriminate tachycardia mechanism and may reduce inappropriate ICD shocks.

    Notes: Objective  To examine whether a previous caesarean section increases the risk for complications in women undergoing a mid-trimester pregnancy termination by labour induction.Design  Retrospective analysis of case records between 1997 and 2002.Setting  Fetal Medicine Unit of a large teaching hospital.Population  One hundred and eight women with a previous caesarean section (study group) and 216 women without such a history (controls), who underwent a second trimester termination of pregnancy.Methods  All the terminations were performed between 17 and 24 weeks of gestation by using 400 μg of oral administration of misoprostol in combination with 400 μg of intravaginal misoprostol. The same dose of intravaginal misoprostol was repeated every 6 hours for a maximum of five doses.Main outcome measures Severe haemorrhage requiring blood transfusion, post-abortal infection, retained placenta and uterine rupture.Result  Complications occurred in 16 out of 108 women of the study group (15%) and in 26 out of 216 of the controls (12%), with only one ruptured uterus in the control group.Conclusion  We found no evidence that a previous caesarean delivery affects the incidence of complications when women with such a history undergo a mid-trimester pregnancy termination with misoprostol.
