The study evaluated the performance of a tined, quadripolar defibrillation lead (model 6944) that has a small-surfaced, steroid-eluting electrode tip for high impedance pacing. In a prospective, controlled study, 34 patients with conventional ICD indications were randomized one to one to receive the high impedance model 6944 or a tined defibrillation lead with a conventional sized, steroid-eluting electrode tip model 6942. Lead Performance was evaluated at implant, prior to hospital discharge, and 1, 3, 6, and 12 months thereafter. Baseline characteristics did not differ significantly between patients implanted with lead model 6942 (n = 16) or model 6944 (n = 17). One patient randomized to receive the model 6942 was excluded from the study and was implanted with an active-fixation lead after stable lead positioning was neither possible with the 6942 nor with the 6944 electrode. No other lead related adverse events were observed. At implant, there were no significant differences between pacing thresholds, sensing performance, defibrillation impedances, and defibrillation thresholds in both groups, but pacing impedance of the model 6944 (988.6 +/- 217.7 Omega) was approximately twice as high as in the model 6942 (431.7 +/- 83.7 Omega; P < 0.0001). This difference remained highly significant throughout the observation period of 12 months, while R wave amplitudes and pacing thresholds remained equal in both lead models. The use of a tined defibrillation lead with a small, steroid-eluting electrode tip appears safe and results in a high pacing impedance without compromising system performance."],["dc.identifier.doi","10.1046/j.1460-9592.2002.01577.x"],["dc.identifier.isi","000179508100007"],["dc.identifier.pmid","12494614"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/36464"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Futura Publ Co"],["dc.relation.issn","0147-8389"],["dc.title","1-Year performance of a defibrillation lead with a small electrode surface for high impedance pacing: A randomized, controlled study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

We aimed to evaluate the effect of CRT alone and CRT + AOP on CSA in CHF patients and to compare the influence of CRT on CHF between CSA positive and CSA negative patients. Methods and results Thirty patients with CRT indication underwent full night polysomnography, echocardiography, exercise testing, and neurohumoral evaluation before and 3 months after CRT implantation. In CSA positive patients (60%), two additional steep studies were conducted after 3 months of CRT, with CRT alone or CRT + ACIP, in random order. Cardiac resynchronization therapy resulted in significant improvements of NYHA class, left ventricular ejection fraction, N-terminal pro-brain natriuretic peptide, VO(2)max, and quality of life irrespective of the presence of CSA. Cardiac resynchronization therapy also reduced the central apnoea-hypopnoea index (AHI) (33.6 +/- 14.3 vs. 23.8 +/- 16.9 h(-1); P < 0.01) and central apnoea index (17.3 +/- 14.1 vs. 10.9 +/- 13.9 h(-1); P < 0.01) without altering steep stages. Cardiac resynchronization therapy with atrial overdrive pacing resulted in a small but significant additional decrease of the central AHI (23.8 +/- 16.9 vs. 21.5 +/- 16.9 h(-1); P < 0.01).

We evaluated cyclosporine (CSA) dose reduction and mycophenolate mofetil (MMF) treatment versus maintained CSA dosage and azathioprine (AZA) in HTX regarding renal function and safety from CSA nephrotoxicity (creatinine > 1.7 mg/dL). Methods. Fourteen recipients (group 1: 12 men, 2 women) with CSA-based immunosuppression (plus azathioprine and/or steroids) were started on 2000 mg MMF/d. Azathioprine was discontinued and CSA tapered to trough whole blood levels of 70 to 120 mug/L. Ten recipients (group 2: seven men, three women) were maintained on their CSA dosages. Creatinine clearance, serum creatinine, uric acid, urea nitrogen, and rejection were monitored. Results. Mean age was 58 (range 44 to 69 years) and 48 years (range 24 to 61 years) in groups 1 and 2, respectively. In group 1 creatinine fell from 2.7 +/- 0.8 to 1.9 +/- 0.5 mg/dL (baseline vs control 2: P = .001); uric acid and urea nitrogen remained constant. CSA levels decreased from 173 +/- 56 to 110 +/- 33 mug/L (P = .02). In group 2 creatinine (2.4 +/- 0.7 vs 2.3 +/- 0.5 mg/dL), uric acid, urea nitrogen, and CSA levels remained constant. Comparison between groups showed higher creatinine clearance (50 +/- 18 vs 29 14 mL/min; group 1 vs group 2: P = .02), lower CSA levels (110 33 vs 161 +/- 35 mug/L; P < .001) and a trend toward lower serum creatinine (1.9 +/- 0.5 vs 2.3 +/- 0.5 mg/dL, P = .077). There were two rejections greater than or equal to 1B according to ISHLT in the study and four in the control group. Two deaths occurred in each group.
