BACKGROUND: The rapid evolution of implantable cardioverter-defibrillator (ICD) leads has resulted in thinner active fixation leads. While these advances have made the leads more versatile, new configurations may be associated with unforeseen complications. OBJECTIVE: The purpose of this study was to determine the incidence of perforation and dislodgement of defibrillator leads in a single center in the year 2005. METHODS: All patients who underwent percutaneous ICD implantation at the Massachusetts General Hospital using an endocardial right ventricular lead were included in this study. The specific leads analyzed were the Riata (1580/1581 and 1590/1591, St. Jude Medical, St Paul, Minnesota, USA;) and Sprint Fidelis (6949-65, Medtronic, Minneapolis, Minnesota, USA.). Information was collected retrospectively. RESULTS: A total of 130 Riata leads and 111 Sprint Fidelis leads were implanted at the Massachusetts General Hospital during this time period. A total of five lead perforations occurred in patients implanted with the Riata lead as compared with none with the Sprint Fidelis lead (3.8% vs. 0%, respectively; P <.05). Two of the five patients with perforation required pericardiocentesis for tamponade. Clinical symptoms of perforation developed 1-10 days after implant. Moreover, there were five additional lead revisions in the Riata group, which were likely due to dislodgement and/or microperforation, as compared with none in the Sprint Fidelis group (7.7% vs. 0%, respectively; P <.005). CONCLUSIONS: In 2005, at one institution, there were significantly more cardiac perforations and lead revisions with the Riata lead as compared with the Sprint Fidelis right ventricular defibrillator lead. Further data are required to determine whether certain lead characteristics are responsible for this observation. 相似文献

Objective Integration of 3-D electroanatomic mapping with Computed Tomographic (CT) and Magnetic Resonance (MR) imaging is gaining acceptance
to facilitate catheter ablation of atrial fibrillation. This is critically dependent on accurate integration of electroanatomic
maps with CT or MR images. We sought to examine the effect of patient- and technique-related factors on integration accuracy
of electroanatomic mapping with CT and MR imaging of the left atrium.
Materials and methods Sixty-one patients undergoing catheter-based atrial fibrillation (AF) ablation procedures were included. All patients underwent
cardiac CT (n = 11) or MR (n = 50) imaging, and image integration with real-time electroanatomic mapping of the aorta and left atrium (LA). CARTO-Merge
software (Biosense-Webster) was used to calculate the overall average accuracy of integration of electroanatomic points with
the CT and MR-derived reconstructions of the LA and aorta.
Results There was a significant correlation between LA size assessed by electroanatomic mapping (112 ± 31 ml) and average integration
error (1.9 ± 0.6 mm) (r = 0.46, p = 0.0003). There was also greater integration error for patients with LA volume ≥ 110 ml (n = 31) versus < 110 ml (n = 30) (p = 0.004). In contrast, there was no significant association between average integration error and paroxysmal versus persistent
AF, left ventricular ejection fraction, days from imaging to electroanatomic mapping, or images derived from CT versus MR.
Conclusions Patients with larger LA volume may be prone to greater error during integration of electroanatomic mapping with CT and MR
imaging. Strategies to reduce integration error may therefore be especially useful in patients with large LA volume. 相似文献

A 2½-year-old girl developed a bilateral occipital infarct following severe gastroenteritis with bilateral vision of light perception. Evaluations for sickle cell anemia, hemolytic anemia and coagulopathies were negative. Cortical blindness is an uncommon but dramatic complication of gastroenteritis, hence the need of prompt hydration and other supportive measures to avoid irreversible visual loss or mental sequela.Key Words: Occipital infarct, Gastroenteritis, Visual recovery 相似文献
