Abstract

Background and Study Aims. Capsule endoscopy is an established tool for investigation of the small intestine. Because of limited clinical experience in patients with cardiac devices, the Food and Drug Administration and the manufacturer recommended not to use capsule endoscopy in these patients. The vast majority of investigations did not reveal any interference between capsule endoscopy and cardiac devices. Methods. Studies investigating interference between CE and cardiac devices were analysed. For the review we considered studies published in English or German and indexed in Medline, as well as highly relevant abstracts. Results. In vitro and in vivo studies mainly revealed no interference between capsule endoscopy and cardiac devices. Technical data of capsule endoscopy (Given Imaging) reveal that interference with cardiac pacemakers and implantable cardioverter defibrillator is impossible. Telemetry can interfere with CE video. Conclusion. The clinical use of capsule endoscopy (Given Imaging) is unproblematic in patients with cardiac pacemakers.

Abstract

Background & Aims. Capsule endoscopy (CE) is an established tool for the investigation of the small intestine. The Food and Drug Administration, Given Imaging and Olympus have not recommended the use of capsule endoscopy in patients with cardiac pacemakers and implantable cardioverter defibrillators (ICDs). The aim of this retrospective study was to investigate the safety of capsule endoscopy systems (Given Imaging and Olympus) when applied in patients with different types of pacemakers/ ICDs in vivo. Methods. A standardized questionnaire was sent to high volume centers in Germany and in Austria. The questionnaire covered the age and gender of the examined patients, indication of CE, brand and type of CE, brand and model of pacemaker/ICD, check of the devices before and after CE, monitoring during CE, possible interference between CE and cardiac pacemakers/ICDs and possible adverse events during CE. Results. Data from 62 patients were retrieved for this study. Capsules used were Given Imaging (n=58; M2A, M2Aplus, PillCam SB2), Olympus EndoCapsule (n=3), Given PillCam Colon (n=1). The collective included patients with pacemakers/ICDS from seven brands (Biotronik, Medtronic, St. Jude Medical, Guidant, Boston Scientific, Ela Sorin, Vitatron) with a total of 19/8 (pacemaker/ICD) different types. In two patients interference between capsule endoscopy and telemetry (loss of images/gaps in video) was recorded. None of the cardiac pacemakers or ICDs was impaired in function. No clinically evident event was observed in any of these patients. Conclusions. Clinical use of these CE types is safe in patients with cardiac pacemakers and ICDs. Interference can occur between CE and ECG-telemetry leading to loss of images or impaired quality of video. [ABSTRACT FROM AUTHOR]

Abstract

Background: Contrast-induced acute kidney injury (CI-AKI) is a serious complication of procedures requiring contrast media associated with rising costs, prolonged hospitalization, and increased mortality. The aim of this study was to assess whether prophylactic administration of standard dosages of intravenous N-acetylcysteine or ascorbic acid reduce the incidence of CI-AKI in patients with chronic renal insufficiency undergoing elective cardiac catheterization., Methods: In a single-center, prospective, randomized, double-blind, placebo-controlled trial, the preventive effects of N-acetylcysteine and ascorbic acid were evaluated in 520 patients with chronically impaired renal function (serum creatinine ≥1.3 mg/dL) undergoing elective cardiac catheterization. The study drugs (600 mg N-acetylcysteine, 500 mg ascorbic acid, placebo) were administered intravenously twice (at 24 hours and 1 hour before the procedure). Serum creatinine, estimated glomerular filtration rate (eGFR) and serum urea were assessed at baseline and at 24 hours and 72 hours after contrast media exposure. CI-AKI was defined as a postangiographical increase in serum creatinine ≥0.5 mg/dL. Results. The incidence of CI-AKI was 27.6% in the N-acetylcysteine group (P=.20 vs placebo group) and in 24.5% in the ascorbic acid group (P=.11 vs placebo group). CI-AKI occurred in 32.1% of the placebo group., Conclusions: Standard doses of N-acetylcysteine and ascorbic acid did not prevent CI-AKI in patients at high risk undergoing cardiac catheterization with non-ionic, low-osmolality contrast agent.
