介入性心导管术作为一种有创性的心血管疾病诊疗手段,具有免除开胸、创伤小、痛苦少、效果迅速、可反复使用、较为安全等优点,特别适合于外科手术危险性较大、药物治疗无效的病人.目前此法在临床上已广泛应用,但常需在X线的透视下进行.超声心动图应用于监护心导管术已取得了一定的成效,如引导漂浮导管定位、心内膜心肌活检和瓣膜球囊成形等.近年来,经食道超声心动图(TEE)技术的兴起和不断完善,显示出比经胸壁超声心动图(TTE)更为优越,使其在介入性心导管术中的应用也越来越广泛,现就其应用现状介绍如下.
Cardiac catheterization, as an invasive treatment of cardiovascular disease, has the advantages of eliminating thoracotomy, less trauma, less pain, rapid effect, reusable and safer, especially suitable for surgical operation , Drug therapy invalid patients.Currently this method has been widely used in clinical practice, but often need to X-ray fluoroscopy. Echocardiography used in care cardiac catheterization has achieved some success, such as the guidance of floating catheter positioning, Endomyocardial biopsy and valvuloplasty, etc. In recent years, the rise and continuous improvement of transesophageal echocardiography (TEE) technique has shown that it is superior to transthoracic echocardiography (TTE) The application of cardiac catheterization is also more and more widely, now the status of its application is described below.
