心耳起源的房性心动过速性心肌病相关病例分析

Cases study on myocardiopathy induced by atrial tachycardia originating from the atrial appendage

心耳起源的房性心动过速少见,其发作多呈无休止性,易形成心动过速性心肌病,治疗难度大,射频消融治疗成功率亦稍低,容易复发,应给予个体化治疗,采用综合治疗方案,提高治愈率。本文报道少见的起源于心耳的房性心动过速引起的心肌病病例4例。其中,3例为心动过速性心肌病,1例有心脏扩大的趋势。2例起源于左心耳,2例起源于右心耳,都有无休止发作的特点。其中2例行导管射频消融成功;1例导管射频消融失败,给予药物治疗;1例行外科右心耳部分切除术,4例患者均治愈。

The atrial tachycardia originating from the atrial appendage is uncommon.It presents incessant tachycardia and may results in myocardiopathy induced by atrial tachycardia,which is hard to treat and easy to relapse.These patients should be treated individually and comprehensively to improve cure rate.In this paper,four cases of atrial tachycardia were reported,among which,three cases were identified as myocardiopathy induced by atrial tachycardia,and one case has the tendency of cardiac dilatation.In addition,in the four cases,two of them were originated from left atrial appendage,while the other two were originated from the right atrial appendage.All the cases presented incessant tachycardia.All the patients were successfully cured,among which,two cases were cured by radiofrequency ablation,one case was treated with drugs after unsuccessful radiofrequency ablation,and one case was performed by partial right auricular appendectomy.
