Filter by:Patients with documented atrial fibrillation who were referred to our clinic for catheter ablation will undergo standard HPSD ablation and subsequent esophagoscopy. After esophagoscopy patients will be followed up for one month in the form of a telephone follow-up. The primary endpoint of the study assessed by esophagoscopy performed on the day after the index catheter ablaton is the incidence of esophageal thermal lesions. Secondary endpoints include: 1. The size of the esophageal thermal lesions. 2. The severity of esophageal thermal lesions.
The most common adverse event in endoscopic procedures is hypoxia. Different airway devices have been investigated in the literature to prevent hypoxia. This study aimed to compare the efficacy and procedural performance of two different airway (GLT and WNJ) devices in ERCP procedures.
Comparison of second generation supraglottic airway devices about anesthesiologist, endoscopist and patient, which used for gastrointestinal procedures. The investigators believe that the endoscope will be easier to reach by the part of GLT extending to the esophagus, but the structural stiffness of this part may damage the esophageal mucosa. On the other hand, since the endoscopic canal of the LMA® Gastro ends at the upper end of the esophagus, it may be more difficult to orient the endoscope to the esophagus, but it may be superior in terms of ventilation efficiency. Therefore these two device worth for comparing.
The POWER FAST I pilot study is a unicentric, observational, non-randomized controlled clinical study. In the control group pulmonary veins isolation was performded in consecutive patients with irrigated radiofrequency cateters without contact force-sensing capabilities and using conventional low-power and long-duration radiofrequency parameters (20-30 W, 30-60 s) under continuous intracardiac-echo image and esophageal temperature monitoring. The study group consist of consecutive patients distributed in three succesive subgroups. In the study group radiofrequency ablation was performed using a point-by-point technique with contact-force catheters with different high-power and short-duration parameters: - Subgroup 50W: power 50 W, application duration ≤ 30 s, target lesion index: LSI ≥ 5 or Ablation Index ≥ 350 (posterior wall) or ≥400 (anterior wall). - Subgroup 60W: power 60 W, application duration 7-10 s, contact force ≥5 g. - Subgroup 70W: power 70 W, application duration 9 s, contact force ≥5 g. The safety endpoint was evaluated with systematic esophageal endoscopy performed <72 h after the index procedure. The efficacy endpoint was evaluated: - during the ablation procedure: acute procedural efficacy, firts-pass isolation of ipsilateral pulmonary veins, total radiofrequency and procedural time, acute reconnections and dormant conduction, - during the follow-up: any atrial tachycardias documented and longer than 30 s were considered recurrences.
