جهاز المساعدة الأذينية
Graphic describing a Left Ventricular Assist Device (LVAD). The device pumps blood from the left ventricle to the aorta.
جهاز المساعدة الأذينية Ventricular assist device، أو VAD، هو جهاز يستخدم ليقوم بوظيفة القلب بصفة جزئية أو كاملة في حالات فشل القلب. بعض أجهزة المساعدة الأذينية تستخدم لفترات قصيرة، مثل تلك التي تستخدم لعلاج النوبات القلبية أو جراحة القلب، بينما توجد أجهزة أخرى تستخدم لفترات طويلة (شهور أو سنوات وفي بعض الأحيان طول العمر)، مثل التي يستخدمها المرضى المصابون بفشل القلب الاحتقاني.
