限制型心肌病与缩窄性心包炎均以相似的心力衰竭为主要临床表现,即使经多种无创性和血流动力学检查方法,鉴别两者仍感困难,但两者的治疗和预后完全不同。鉴于开胸探查进行鉴别诊断不可取,故确立新的诊断方法很有必要。经静脉心内膜心肌活检(TEMB)用于诊断原因不明的心衰日益增多,故作者对有心衰症状,考虑为限制型或缩窄性综合症而有开胸探查指征的患者,进行TEM-B,旨在评价TEMB对限制心肌病和缩窄性心包炎的诊断价值.
Restrictive cardiomyopathy and constrictive pericarditis are similar to the main clinical manifestations of heart failure, even though a variety of noninvasive and hemodynamic tests to identify both are still difficult to identify, but the treatment and prognosis of both completely different. In view of differential diagnosis of chest exploration is not desirable, so the establishment of new diagnostic methods is necessary. Intravenous endocardial myocardial biopsy (TEMB) for the diagnosis of unexplained increases in heart failure, so the author of heart failure symptoms, consider limited or constrictive syndrome patients with thoracic exploration indications, the TEM-B, to evaluate the diagnostic value of TEMB to limit cardiomyopathy and constrictive pericarditis.
