The relationship between adherence to the recommended CoreValve sizing parameters and clinical outcomes is not well known for the recently released 34 mm valve, which is currently the largest available transcatheter valve. There is a presumed temporal reduction in paravalvular regurgitation in patients who receive an in-range valve, however, certain patients possess annular dimensions that are too large. We therefore describe two patients with annular dimensions larger than the manufacturer recommended range for the 34 mm CoreValve, who despite this underwent transcatheter aortic valve replacement with excellent clinical outcomes.
最近推出的 34 毫米瓣膜是目前可用的最大经导管瓣膜，但其推荐的核心瓣膜尺寸参数的依从性与临床结果之间的关系尚不清楚。接受合适尺寸瓣膜的患者，瓣周漏的情况会出现暂时减少，但某些患者的瓣环尺寸过大。因此，我们描述了两位瓣环尺寸大于 34 毫米 CoreValve 制造商推荐范围的患者，尽管如此，他们仍接受了经导管主动脉瓣置换术，取得了良好的临床效果。
