What Is a LVAD? A left ventricular assist device (LVAD) is a pump that we use for patients who have reached end-stage heart failure. We surgically implant the LVAD, a battery-operated, mechanical pump, which then helps the left ventricle (main pumping chamber of the heart) pump blood to the rest of the body. LVADs can be used as:

2023年5月3日 · When placed in the left ventricle, it's called a left ventricular assist device (LVAD). This article focuses on LVADs. Current LVADs provide a constant flow of blood from the heart to the body. They also are called continuous flow devices. Getting an LVAD often requires open-heart surgery and has serious risks.

What is a left ventricular assist device? A left ventricular assist device (LVAD) is a mechanical pump that providers implant in people who have heart failure. The device helps the lower left chamber (left ventricle) of your heart pump blood out of …

Left ventricular assist device implantation is performed during an open-heart surgery, which takes several hours in the hospital. Your surgical team will: After LVAD surgery, you’ll likely receive IV medications to prevent infections and thin your blood. Other tubes may drain fluids from the surgical wounds and urine from your bladder.

2023年8月8日 · Circulatory support with the use of a left ventricular assist device (LVAD) is an emerging field. The landmark REMATCH trial that compared LVADs with optimal medical therapy in class IV HF patients found a 48% reduction in mortality from any cause [4].

2022年12月14日 · Durable implantable left ventricular assist devices (LVADs) have been shown to improve survival and quality of life for patients with stage D heart failure. Even though LVADs remain underused overall, the number of patients with heart failure supported with LVADs is steadily increasing.

LVADs represent a significant advance in that they allow patients who were critically ill to survive to transplant and to function including becoming physically active. As the technology has improved and outcomes have improved, LVADs have become viable and realistic alternatives for patients who might not be optimal transplant candidates.

Once implanted, the LVAD is designed to help the left ventricle of your patient’s heart pump blood to the rest of their body. LVADs can be used as bridge-to-transplant therapy and/or destination therapy. LVADs are an important therapy option for patients with Class IIIB or IV heart failure.

2023年9月3日 · A left ventricular assist device, or LVAD, is a mechanical pump that is implanted inside a person's chest to help a weakened heart pump blood. Unlike a total artificial heart, the LVAD...

左心辅助装置（LVAD）是一个可提供动力的 血泵，其效能较IABP高6-8倍，能有效代替心脏工作能力的80%以上，泵血能力可达到10L/min。 LVAD的特点和适应征 IABP 仅能改善已存在的循环动力，左心辅助是将 左心房 或左心室血流引入辅助泵体，经泵体驱动血流进入主动脉，完全替代左心 泵血功能。 经左心辅助后，左心室室内张力可降低80%，心肌氧需求降低40%，是纠正 顽固性心衰 和 心脏移植 前的一种理想治疗手段。
