- Tandem Heart®
The TandemHeart™ Percutaneous Ventricular Assist Device (pVAD) can be inserted the cardiac catheterization laboratory to assist patients suffering from postcardiotomy cardiogenic shock. This device buys valuable time for the surgeons to decide on the next course of treatment, and provides short-term support from a few hours for up to fourteen days. During the time, the heart may also strengthen and potentially regain its native function.
Cannulas are inserted through the femoral vein then advanced into the left atrium. The pump withdraws oxygenated blood from the left atrium, then a magnetically driven, six-bladed impeller sends it through the outflow port, returning it to one or both femoral arteries through arterial cannulas. Weighing only eight ounces, the pump is capable of delivering blood flow up to 5.0 liters per minute.
