Long-Term Results of Cryoablation with a New Cryoprobe to Eliminate Chronic Atrial Fibrillation Associated with Mitral Valve Disease 总被引:2,自引:0,他引:2

The purpose of this study was to examine the performance of a new cryoprobe in the treatment of chronic atrial fibrillation (AF) associated with mitral valve disease. The study included 66 patients undergoing mitral valve replacement. The mean AF duration was 9.0 ± 9.0 years and mean left atrial (LA) was diameter 57 ± 10 mm. Cryoablation (−60°C) was applied to four pulmonary vein (PV) orifices over 2–3 minute. The spherical tip (2-cm in diameter) of the cryoprobe is capable of ablating the left atrium near the PV, as well as the PV ostium with a single cryoablation. After cryoablation, mitral valve surgery or a combined surgical procedure were performed in 66 patients. There were no intraoperative complications. Sinus rhythm was restored in 60 patients (91%) immediately after the operation. Recurrent AF was treated with antiarrhythmic drugs and/or direct current cardioversion in 43 patients (72%). At discharge, 48 patients (72%) were in sinus rhythm. During a mean follow-up period of 31 ± 16 months, 40 patients (61%) were in sinus rhythm with (29) or without antiarrhythmic drugs (11). In patients in sinus rhythm at the end of the follow-up period, the duration of preoperative AF duration was significantly shorter (P < 0.05) and the preoperative LA diameter and cardiothoracic ratio were significantly smaller than in patients who were in AF (both for P < 0.005). Using this new cryoprobe, sinus rhythm was restored and maintained in 61% of patients with chronic AF and mitral valve disease with a 12–15 minute cryoablation procedure. 相似文献

BACKGROUND: Data on female partners' satisfaction are scarce, although there have been many articles on patient satisfaction after sildenafil citrate treatment. The aim of this study was to evaluate the satisfaction of female partners of patients receiving sildenafil citrate for their erectile dysfunction (ED) and to assess the female partners' sexual function. METHODS: Ninety-eight patients with ED were treated. Their female partners were asked to answer a questionnaire we have prepared to evaluate the efficacy of treatment, sexual satisfaction and changes in quality of life. It also included a question about female sexual function. From the results, the relationship between their female partner's satisfaction and efficacy of treatment, as well as female sexual function, were assessed. RESULTS: Thirty (31%) questionnaires were returned to us for analysis. Effectiveness of the treatment was acknowledged by 90% of the partners. An improvement in their partner's quality of life was noticed by 60% of the women. The majority (66.7%) of the female partners were satisfied with sildenafil citrate treatment and 20% were disappointed. Moreover, 20% of the female partners were concerned about adverse events. Regarding female sexual function, some form of sexual dysfunction affected 46.7% of the women. Furthermore, a significant number (P = 0.0230) of the female partners disappointed with the treatment had some kind of sexual dysfunction. CONCLUSIONS: The results indicated that female partners reported relatively high levels of treatment satisfaction. Female partners' sexual function and anxiety regarding adverse events should be evaluated when their satisfaction with sildenafil citrate treatment is poor despite an improvement of erectile function. 相似文献

We describe the appearance of complete atrioventricular block (CAVB) with sevoflurane and nitrous oxide during the slow induction in a ten-year-old male patient with hypertension, renal dysfunction, and impaired cardiac conduction. Sinus rhythm was restored following the washout of the anaesthetic gas. And CAVB recurred after the subcutaneous injection of lignocaine. The present report shows that sevoflurane should be treated with care like other inhalational anaesthetics as regards the effect on cardiac conduction. 相似文献

PURPOSE: The incidence of prostate cancer, benign prostatic enlargement and serum level of prostate-specific antigen (PSA) increase with patient age. Intermediate elevation of PSA in elderly populations is apt to be considered insignificant. We evaluated the impact of PSA and prostate volume on the presence of non-palpable prostate cancer in elderly men with an intermediate level of PSA. MATERIALS AND METHODS: Clinical records of 154 men 70 years or older, with non-cancerous digital rectal examination findings and with serum PSA levels of 2.0-10.0 ng/mL, who underwent initial 6- to 10-core transrectal prostate biopsy, were reviewed for prostate volume, number of biopsy cores, PSA and associated parameters. Stepwise logistic regression and receiver operating characteristic (ROC) models were used to determine the impacts of the parameters on the biopsy results. RESULTS: Overall cancer detection rate was 40/154 or 26.0%. Prostate-specific antigen showed no significant association with the presence of prostate cancer (P = 0.59, Mann-Whitney U-test), while prostate volume did (P < 0.0001). On stepwise logistic regression analysis, prostate volume (P = 0.024, 95% CI 1.008-1.116) and biopsy core density (P = 0.017, 95% CI 4.76-7.12 x 10(6)) were independently associated with a cancer diagnosis, whereas PSA density was not an independent factor for a positive biopsy result. The area under the ROC curve for prostate volume was significantly superior to that of PSA (0.802 vs. 0.529; P = 0.012). CONCLUSIONS: In men 70 years or older with gray zone PSA, prostate cancer patients are equally distributed over any PSA range. Although PSA has less impact on cancer presence than mere prostate volume, prostate cancer would be detected in a substantial proportion of older patients with PSA levels of 2.0-10.0 ng/mL. 相似文献

Abstract In the present study, the effect of methamphetamine (MAP) on histamine (HA) release measured by in vivo brain microdialysis in the rat hypothalamus was investigated. Administration of MAP (3 mg/kg) significantly increase HA release from 40 to 160 min after the injection. This finding suggests that a moderate dose of MAP activates the hypothalamic HA neuron system, which may be related to effects of MAP on intrinsic biological rhythms. 相似文献

Antibody to p40tax (anti-p40tax) in serum specimens obtained sequentially from a human T cell lymphotropic virus type I carrier population of mothers and children were assayed. The prevalences of anti-p40tax at the initial sampling were 88% (7/8) in children and 55% (16/29) in mothers. Two of the seven positive children lost their anti-p40tax during the investigation period, resulting in a final prevalence of 63% (5/8) in children. However, anti-p40tax status was constant in all the 22 mothers with multiple serum samples (15 remained positive and seven remained negative). A decline in the absorbance value of EIA for anti-p40tax was observed in seven of the 15 anti-p40tax positive mothers. This decline may result in the disappearance of anti-p40tax in some of them. 相似文献

Accidental transmission of contagious pathogens, especially hepatitis C virus (HCV), by needlestick or other means as an occupational hazard for medical staff is of concern. We retrospectively analysed cases of work-related accidental injury with pathogens such as hepatitis B virus (HBV), HCV, syphilis and human immunode?ciency virus (HIV) reported to the centres for disease control at 15 hospitals (total 5776 beds) in the Gunma prefecture, Japan, from December 1990 to August 1993 (24.7 months). There were 416 such cases (16.8 cases/month), with an incidence of 0.2–3.5 accidents per month per hospital. Such accidents occurred in 297 (71.2%) nurses, 98 (23.5%) medical doctors, 13 (3%) laboratory technicians, four (1.0%) hospital maintenance workers, one (0.2%) assistant nurse, one secretary and two others. There were 323 (77.6%) injuries caused by needlestick, 42 (10.1%) from suture needles or surgical knife cuts, 17 (4.1%) from blood splatters from patients into the eyes or mouth, 10 (2.4%) from contact with injured skin and 24 (5.8%) simple skin contacts. Of the pathogens, 60.3% were HCV, 22.6% HBV, 5.8% syphilis, 0.7% HIV and 10.6% were of unknown origin. Four cases (1.6%) of HCV infection were found and treated with one or two courses of interferon therapy, and HCV was subsequently cleared. All four patients were cured with interferon therapy. None of the HBV-injured cases resulted in infection, possibly because of prophylaxis with HB immunoglobulin and HB vaccine. No HIV or syphilis infection was contracted. In summary, chronic HCV infection acquired as an occupational hazard can be cured by appropriate treatment, such as with interferon, after early detection of the infection. 相似文献
