RESUMO
Fibrosing mediastinitis (FM) is a rare disease caused by different causes. If left untreated, the prognosis is poor. The common causes of FM are Tuberculosis and Histoplasma capsulatum infection. Esophageal perforation is also a rare condition that is often easily under- and mis-diagnosed due to the lack of specificity of symptoms. Here we report a case of FM caused by esophageal perforation.
RESUMO
INTRODUCTION: A considerable amount of studies have been published with the results of clinical benefit from his bundle pacing (HBP) for chronic heart failure (CHF) patients and these researches led a uncertain conclusion for clinics. Thus, we will conduct a meta-analysis to evaluate the effect of his bundle pacing therapy for chronic heart failure. METHODS: Pubmed, EMBASE, the Cochrane Library, Web of Science and Chinese online databases including Chinese National Knowledge Infrastructure, China Biology Medicine disc, Chinese Scientifific Journals Database (VIP), and Wanfang Database will be searched from these databases construction to the end of November, 2020. The STATA 13.0 will be used for data synthesis and meta-analysis. RESULTS: The outcome measures included QRS duration, left ventricular ejection fraction, pacing threshold, New York Heart Association (NYHA), left ventricular end-diastolic diameter, left ventricular end-systolic diameter, mitral regurgitation, tricuspid regurgitation, and BNP will be analyzed and synthesized. CONCLUSION: This meta-analysis will evaluate the effect of his bundle pacing therapy for chronic heart failure. REGISTRATION NUMBER: INPLASY202110109.
