BACKGROUND Utilization of catheter ablation of ventricular tachycardia (VT) has steadily increased in recent years. Exploring short-term outcomes is vital in health care planning and resource allocation. METHODS The Nationwide Readmissions Database from 2010 to 2014 was queried using the ICD-9 codes for VT (427.1) and catheter ablation (37.34) to identify study population. Incidence, causes of 30-day readmission, in-hospital complications as well as predictors of 30-day readmissions, complications, and cost of care were analyzed. RESULTS Among 11 725 patients who survived to discharge after index admission for VT ablation, 1911 (16.3%) were readmitted within 30 days. Paroxysmal VT was the most common cause of 30-day readmission (39.51%). Dyslipidemia, chronic kidney disease (CKD), previous CABG, congestive heart failure (CHF), chronic pulmonary disease, and anemia predicted increased risk of 30-day readmissions. The overall in-hospital complication rate was 8.2% with vascular and cardiac complications being the most common. Co-existing CKD and CHF and the need for mechanical circulatory support (MCS) predicted higher complication rates. Similarly increasing age, CKD, CHF, anemia, in-hospital use of MCS or left heart catheterization, teaching hospital, and disposition to nursing facilities predicted higher cost. CONCLUSION Approximately one in six patients was readmitted after VT ablation, with paroxysmal VT being the most common cause of the readmission. A complication rate of 8.2% was noted. We also identified a predictive model for increased risk of readmission, complication, and factors influencing the cost of care that can be utilized to improve the outcomes related to VT ablation.

与患者室性心动过速导管消融相关的短期结果。

背景技术近年来，心室心动过速（VT）的导管消融的使用稳步增加。探索短期结果对于医疗保健计划和资源分配至关重要。方法使用ICD-9 VT（427.1）和导管消融（37.34）来查询2010年至2014年的全国再入院数据库，以识别研究人群。分析了发病率，30天再入院的原因，医院内并发症以及30天再入院率，并发症和护理费用的预测因素。结果在11 725例接受VT消融的入院患者中存活出院的患者中，有1911例（16.3％）在30天内重新入院。阵发性室速是30天再入院的最常见原因（39.51％）。血脂异常，慢性肾脏病（CKD），以前的CABG，充血性心力衰竭（CHF），慢性肺病和贫血预测30天再次入院的风险增加。总体院内并发症发生率为8.2％，其中最常见的是血管和心脏并发症。CKD和CHF并存，以及对机械循环支持（MCS）的需求预示了更高的并发症发生率。同样，随着年龄的增长，CKD，CHF，贫血，医院内使用MCS或左心导管插入术，教学医院以及对护理设施的处理也预示着更高的成本。结论VT消融后约有六分之一的患者再次入院，阵发性VT是再次入院的最常见原因。并发症发生率为8.2％。我们还确定了可增加再次入院，并发症，
