We will report complete data at HRS Conclusions: Conductor externalization is also observed in Biotronik Linox leads and fluoroscopic screening may be warranted in this patient population.
Methods: consecutive patients in whom DDD pacing system was implanted between October and March were retrospectively followed up until January The study group consisted of patients who performed at least one follow-up visit.
Follow-up period was We defined the following endpoints: lead malfunction, progression to permanent AF and infective complications. Local or systemic device infection was identified in 8 patients 0.
Reprogramming to AAI was performed in 2 patients 0. In multivariate analysis we considered the following factors: age at implantation, gender, indications, history of paroxysmal AF and access site; only paroxysmal AF prior to implantation was predictive for DDD mode loss HR 2. However, in at least one study, the eso temp monitoring appeared to amplify the risk of eso injury. We hypothesized that non-insulated metal from an eso probe can cause remote RF heating of non-targeted tissue adjacent to the probe.
Beneath the tissue, an insulated or non-insulated single sensor esophageal SSEP or multi-sensor esophageal probe MSEP was arranged at distances of 5, 10, 15, and 20 mm. Each probe had a thermocouple sensor to measure adjacent tissue temp. A set of thermocouples, not attached to ES probes, was used as control and aligned at the same distances from the myocardium. A 4 mm ablation catheter was placed perpendicular to the tissue; RF was delivered at 20 and 50 Watts for 60 seconds, and temps were recorded.
Greater tissue temp rises correlated with closer probe proximity to RF. Probe insulation mitigated the increase in tissue temps from RF ablation. Conclusions: During RFA, higher temps were found in nontargeted tissues adjacent to non-insulated eso probes. This phenomenon may explain the paradoxical increase in eso injury when using metallic eso probes during RFA.
Insulation of eso probes can prevent this problem; further in vivo research is needed to understand the clinical implications. Bigelow, MD, John M. Clark, MD, Grace L. Smith, MD, Neil L. Shannon, MD, Jeremy P. The Catheter Ablation and Reduction or Elimination of Fluoroscopy CAREFL database is both a retrospective and prospective, adult and pediatric tool to help monitor outcomes and understand the areas where improvements can be implemented.
We report the early findings of that database. Methods: The international, voluntary database tracks important demographic data, as well as procedural outcomes.
The database included all mechanisms of tachycardia including supraventricular, as well as ventricular arrhythmias, all age S Poster Session I ranges, and all forms of congenital or acquired heart disease.
Results: The mean patient age was The mean weight was Mean procedure time was Although complications were uncommon, there were 6 major complications 0. Mean fluoroscopy time was 1. There were procedures that did not use fluoroscopy. Fluoroscopy was used in procedures Conclusions: This study data demonstrates that fluoroscopy exposure can be significantly reduced in a multi-institutional setting.
Samuel, MD, Thomas H. All procedures were prospectively recorded in a single-center registry. The purpose of this analysis and identify possible factors of PVI success and outcome in a large patient cohort. Methods: Between and all consecutive PVI cases were included. Type of ablation, procedural data, clinical determinants and ablation outcome was recorded.
Patients were followed in the outpatient clinic for a mean of 2.
Ablation success was defined as freedom from any symptomatic recurrence of AF with or without concomitant antiarrhythmic therapy. Clinical characteristics did not differ between groups. Including all repeat procedures 1. There was no significant difference between both techniques on short-term outcome.
We sought to investigate the impact of sinus rhythm SR maintenance after catheter ablation in pts with persistent AF and severely impaired cardiac function. Patients were assessed for the presence of underlying structural heart disease during index hospitalization. Arrhythmia burden were assessed at 12 months. They research their topic area and provide recommendations for new methods that are needed.
They provide guidance to Study Directors in designing a collaborative study.
Method Advisors serve as experts on specific methods. They answer technical inquiries about the method and provide recommendations for method modifications based on feedback by method users. A collaborative study should not be conducted with a nonoptimized method.
As much experimentation must be done within a single laboratory as possible with respect to optimization, ruggedness, bias, concentration—response curves, and interferences; the critical steps and variables should be determined and the need for their control emphasized. Description of the Method Every step in the analytical method must be described and explained.
Performance specifications and system suitability tests, defined critical points, and convenient stopping points must be incorporated. Descriptions of equipment and reagents should be written generically, if possible, to avoid dependence on specific brand names and allow the method user to determine suitability of those items in his or her own laboratory. The detailed method written by the Study Director should then be tested by an analyst not previously associated with its development.
Collaborators Any scientist experienced in analysis and qualified in the subject matter may collaborate in the study of a method.
Collaborators are chosen by the organizer of the collaborative study from laboratories with an interest in the method, including regulatory agencies, industry, commercial laboratories, and universities.
A collaborator is expected to analyze materials at times indicated, according to a protocol submitted by the Study Director; follow the method exactly this is critical ; report any unavoidable deviation; perform only the number of determinations requested; and supply raw data, graphs, recorder tracings, photographs, or other documentation.
Laboratories invited to participate should have personnel experienced in the basic techniques employed; experience with the method itself is not a prerequisite for selection. Laboratories must realize the importance of the study. A large investment is made in testing the method and this probably will be Safety Committee Safety Committee members have an interest in the safety and health aspects of the validation and use of analytical methods.
Therefore, it is important to have a fair and thorough evaluation of the method. Vacuum packaging is the procedure that results in a reduced oxygen level in sealed package. An evacuated pack collapse around the product so that the pressure inside is seldom much less than atmosphere.
The anaerobic environment of vacuum packaging prevents the growth of spoilage microorganisms especially aerobic ones which are responsible for off odor, slime and texture changes Nunez et al. The aim of the work is to find out the effect of vacuum packaging on quality parameters like moisture content, capsaicin, oleoresin, and total extractable colour during long term storage. Material and methods Sample collection, vacuum treatment and storage Chilli samples var.
Chillies used for vacuum packaging were destemmed to remove stalk to avoid disruption of vacuum. For the light treatments, the bags were stored in the laboratory with normal diffused light as existed without any additional lighting. For dark treatments, the racks were covered with thick black cloth to protect the infiltration of even diffused light and the light intensity was zero.
It has a built in precision balance and a halogen dryer unit that ensures fast heating of the sample and thus guarantees the rapid availability of the measurement results. Capsaicin content Capsaicin content was analyzed as per the method The extract was cooled and filtered into a stoppered test tube through Whatman No.
For peak identification, solution of reference standards were analyzed under similar conditions and their retention time were compared to those of samples. The contribution of each identified compound was expressed as the percentage of its peak area.
