Retrograde Conduction

Conduction from the atria to the ventricles normally occurs via the atrioventricular node–His–Purkinje system. Accessory pathways (APs) directly connect the atrium and ventricle and bypass the atrioventricular node, bridging the mitral or, less commonly, the tricuspid annulus. Concealed APs conduct electrical impulses retrogradely from the ventricles to the atria, but not antegradely from the atria to the ventricles. Approximately 40% of all APs are concealed, and orthodromic atrioventricular reentrant tachycardia due to concealed APs is present in up to 15% of patients with supraventricular tachycardias referred for catheter ablation. Most concealed APs are left-sided, exhibiting non-decremental retrograde conduction. Tachyarrhythmias due to concealed APs are managed similarly to those supraventricular tachycardias associated with manifest APs, and symptomatic tachyarrhythmias are successfully treated by radiofrequency catheter ablation in the majority of patients.

Abstract Background Ventricular arrhythmias (VAs) arising from the origin above pulmonary valve lack comprehensive investigation. This study aimed to disclose the characteristics and radiofrequency catheter ablation (RFCA) outcomes for those VAs. Methods One hundred six VAs arising from the region above pulmonary valve treated with RFCA were included in this study. Results Seventy-five cases were identified in the pulmonary sinus cusps (PSCs, 32 in left sinus cusp (PLC), 15 in right (PRC), 28 in anterior (PAC)) and 31 cases were in the main stem of pulmonary artery (MSPA, 18 above PLC (LMSPA), 3 above PRC (RMSPA), 10 above PAC (AMSPA)). Compared with PSCs VAs, MSPA VAs exhibited a higher R wave amplitude in the inferior leads, a total inferior R amplitude > 5.1 mV predicting MSPA origins. LMSPA, RMSPA and AMSPA VAs resembled PLC, PRC and PAC VAs in electrocardiographic characteristics respectively. No electrophysiological differences were found between PSCs and MSPA VAs. The irrigated-up catheter and R0 Swartz long sheath were more utilized for ablation of PSCs VAs than for MSPA VAs. All these VAs were successfully eliminated by RFCA. Conclusion VAs arising from the origin above pulmonary valve were common. Based on certain electrocardiographic characteristics, they could be roughly located, which contributed to an effective RFCA.

The aim of this study was to measure the accuracy of noninvasively obtained ventricular activation (isolated epicardial vs combined endo-epicardial mapping) as compared with that of standard invasive mapping in patients with ventricular arrhythmias. 94 patients (35 males and 59 females) aged 20 to 67 years (mean age 42.6 years) with ventricular arrhythmias of different localization and etiology and 8 patients (4 males and 4 females) aged 21 to 65 years (mean age 48.8 years) with atrial arrhythmias were examined. All patients underwent noninvasive electrophysiological examination, which was performed with Amycard System, subsequent intracardiac mapping and radiofrequency catheter ablation. The arrythmogenic focus localizations coincided in 83 cases, in 11 patients with ventricular arrhythmias some variances were observed and in patients with atrial arrhythmias no such variances were found. Thus, the accuracy of noninvasive mapping turned out to be 89.2%.
