Cím:	Effect of dual atrioventricular node pathways on atrioventricular reentrant tachycardia / Csanadi Z., Klein G. J., Yee R., Thakur R. K., Li H.
Dátum:	1995
ISSN:	0009-7322
Megjegyzések:	Dual atrioventricular (AV) node pathway physiology is frequently observed in patients with AV accessory pathways. METHODS AND RESULTS: To examine the implications of this, we identified 36 patients (19 men and 17 women; mean +/- SD age, 30 +/- 13 years) with both phenomena. The 36 patients had 48 accessory pathways. Twenty-seven patients had bidirectional and 9 had unidirectional accessory pathways. Of the 34 patients with inducible atrioventricular reentry, 17 used the slow and 11 used the fast anterograde AV node pathway exclusively during AV reentrant tachycardia, whereas 6 patients used both the fast and the slow AV node pathways. AV node reentrant tachycardia was inducible in addition to AV reentry in 7 patients. Both the cycle length and AH intervals were significantly longer during slow pathway-dependent (cycle length, 411 +/- 58 milliseconds [ms]; AH, 229 +/- 42 ms) than during fast pathway-dependent (cycle length, 322 +/- 40 ms; AH, 121 +/- 25 ms; P < .05) reentrant tachycardias. Two patients had only AV node reentrant tachycardia inducible despite the presence of the accessory pathway. Four patients with technically difficult accessory pathways were managed by AV node modification with slow pathway (3) or fast pathway (1) ablation. Three of them remained free of symptoms 7, 14, and 25 months after the procedure whereas 1 patient had recurrence of arrhythmia. CONCLUSIONS: AV reentrance with dual AV node pathways frequently depends exclusively on either the slow or the fast AV node pathway for clinical tachycardia. This may provide additional options for ablation in technically difficult cases when the accessory pathway is not otherwise problematic.

Cím:	Transcranial Measurement of Cerebral Microembolic Signals during Pulmonary Vein Isolation : a Comparison of Two Ablation Techniques / Edina Nagy-Baló, Diana Tint, Marcell Clemens, Ildikó Beke, Katalin Réka Kovács, László Csiba, István Édes, Zoltán Csanádi

Megjegyzések:	BACKGROUND: -Pulmonary vein isolation (PVI) has increasingly been used to cure atrial fibrillation, but concerns have recently been raised that subclinical brain damage may occur due to microembolization during these procedures. We compared the occurrence of bubble formation seen on intracardiac echocardiography (ICE) and the microembolic signals (MESs) detected by transcranial Doppler on the use of different ablation techniques and anticoagulation strategies. METHODS AND RESULTS: -This prospective study included 35 procedures in 34 consecutive patients (age: 52, SD: 12.8 years; female:male 9:25). PVI was performed with a cryoballoon and the conventional anticoagulation protocol (ACT>250 s) in 10 procedures (Group 1), with a multipolar duty-cycled radiofrequency pulmonary vein ablation catheter (PVAC) and the conventional anticoagulation protocol in 12 procedures (Group 2), and with a PVAC with an aggressive anticoagulation regime (ACT>320 s) in 13 procedures (Group 3). The mean total numbers of MESs detected during the procedures were 833.7 (SD: 727.4) in Group 1, 3142.6 (SD: 1736.4) in Group 2 and 2204.6 (SD: 1078.1) in Group 3 (p=0.0005). MESs were detected mostly during energy delivery in the PVAC groups, while a relatively even distribution of emboli formation was seen during cryoballoon ablations. A significant correlation was found in all groups between the degree of bubble formation on ICE and the number of MESs (p=0.0000). CONCLUSIONS: -Duty-cycled RF ablation is associated with significantly more MESs, even when more aggressive anticoagulation is applied. With both techniques most of these microemboli are gaseous in nature.
