Described herein are devices, methods and kits for assessing and/or enhancing the accessibility of a subvalvular space of a heart, accessing the subvalvular space of the heart (e.g., to provide access for one or more other devices), and/or positioning one or more devices in the subvalvular space of the heart. The devices described herein may, for example, comprise catheters that may be used to manipulate one or more chordae tendineae, diagnostic catheters having different sizes and/or shapes (e.g., different curvatures), guide catheters having different sizes and/or shapes (e.g., different curvatures), and visualization catheters. In some variations, the devices, methods, and/or kits may be used to visualize a target site, such as a subannular groove of a heart valve. In certain variations, the devices, methods, and/or kits may be used to manipulate chordae tendineae to provide additional space in a ventricle of a heart (e.g., enhancing the accessibility of the ventricle).
本文描述的是用于评估和/或提高心脏瓣下间隙可及性、进入心脏瓣下间隙(例如,为一个或多个其他装置提供通道)和/或在心脏瓣下间隙定位一个或多个装置的装置、方法和试剂盒。例如,本文所述的装置可包括可用于操作一个或多个腱索的导管、具有不同尺寸和/或形状(如不同弯曲度)的诊断导管、具有不同尺寸和/或形状(如不同弯曲度)的引导导管以及可视化导管。在某些变化中,这些装置、方法和/或套件可用于观察目标部位,如心脏瓣膜的环下沟。在某些变化中,这些装置、方法和/或套件可用于操作腱索,为心脏的心室提供额外空间(例如,提高心室的可及性)。
