The aim: We aimed to assess the feasibility and safety of performing balloon aortic valvuloplasty (BAV) with Valver balloon catheter (Balton, Poland) in adults with severe aortic stenosis as a bridge or palliative treatment.
Materials and methods: We identified consecutive patients who underwent BAV procedures between May 2019 and March 2020 using Valver balloon catheters. Demographic data, medical history, and clinical characteristics were retrospectively collected in all study patients together with periprocedural data as well as 12-month follow-up data.
Results: We included 18 patients. The mean population age was 78.1±8.9 years, and women were 61.1%. The most common co-morbidities were arterial hypertension (88.9%), dyslipidemia (83.3%), and coronary artery disease (72.2%). The baseline mean aortic valve pressure gradient was 49.94±27.02 mmHg and the mean aortic valve area (AVA) was 0.65±0.20 cm2. In all cases, the procedure was performed from the femoral access via the 8F sheath. Two Valver balloon catheter sizes were used 18x40mm (33.3%) and 20x40mm (66.7%). Three periprocedural complications were observed, and none was associated with the Valver balloon catheter per se. The transthoracic echocardiography after the procedure revealed a decrease in the mean pressure gradient of 11.1±8.85 mmHg, and an increase in AVA of 0.21±0.19 cm2. At 12-month follow-up, the mortality rate was 38.9%.
Conclusions: BAV is a procedure increasingly performed in catheterization laboratories worldwide. This paper confirmed the relative safety of BAV with Valver balloon catheters in the modern era, showing a low incidence of valve and vascular complications.
评估经皮球囊主动脉瓣成形术（BAV）联合 Valver 球囊导管（波兰 Balton 公司）在严重主动脉瓣狭窄患者中的可行性和安全性，旨在为患者提供一种过渡或姑息治疗手段。
我们回顾性收集了 2019 年 5 月至 2020 年 3 月期间采用 Valver 球囊导管进行 BAV 治疗的连续患者的资料。所有研究患者均收集了人口统计学数据、既往病史和临床特征，以及围手术期数据和 12 个月随访数据。
我们共纳入 18 例患者，平均年龄为 78.1±8.9 岁，女性占 61.1%。最常见的合并症包括高血压（88.9%）、血脂异常（83.3%）和冠状动脉疾病（72.2%）。基线平均主动脉瓣压力梯度为 49.94±27.02mmHg，平均主动脉瓣面积（AVA）为 0.65±0.20cm2。所有患者均经股动脉入路，采用 8F 鞘管进行操作。球囊导管的使用规格有 18x40mm（33.3%）和 20x40mm（66.7%）两种。3 例患者发生围手术期并发症，但均与 Valver 球囊导管无关。术后经胸超声心动图显示平均压力梯度降低 11.1±8.85mmHg，AVA 增加 0.21±0.19cm2。12 个月随访时死亡率为 38.9%。
BAV 是一种在全球导管室中越来越多地开展的治疗方法。本研究证实了在现代时代使用 Valver 球囊导管进行 BAV 的相对安全性，显示出较低的瓣膜和血管并发症发生率。
