无需手术即可植入的新型心脏泵上市

英国第一种无需手术即可植入患者体内的新型的人工心脏泵首次上市。这种仪器为心肌梗塞发作或者手术之后处于危险期的心肌提供临时支持。

英国国民医疗服务信托Hammersmith医院（Hammersmith Hospitals NHS Trust）的一位患者成为英国首例接受这种作用于心脏的微小仪器。Hammersmith医院的医生成功地将世界上最小的心脏支持系统（该仪器只有4毫米大小）通过腹股沟动脉插管，在导向导线的引导下植入患者的心脏。

这种泵帮助患者的心脏成功度过冠状动脉分流术术后的至关重要的几小时。这种仪器为那些以前被认为过于虚弱以至于不能接受手术的患者提供了希望，因为这种仪器可以为心肌梗塞发作或者手术之后处于危险期的心肌提供临时支持。

这种仪器的植入位置是左心室(心脏最大的腔)。虽然它的体积很小，但是它却能够每分钟泵出多达2.5升的血液。因为它的体积如此之小，它可以无需任何手术就可以植入体内。这种泵使用电动发动机提供能源，使用3毫米的导线，导线伸出患者体外再连接在电池上，控制部分只有一台膝上型电脑大小。该仪器最多可以维持5天。
 
“这些仪器正在变得越来越经济合算，尤其是当你将它们作为其他昂贵治疗（包括反复的侵入性手术、心脏移植、以及住院时间延长等）替代选择的时候”，该医院的心脏外科医生彼得史密斯先生（Peter Smith）表示，“我们对这种仪器能够如此之好地发挥作用感到十分惊喜，对这种技术的未来充满信心。”

New Device: First Heart Pump Inserted without Surgery

For the first time in the UK a new artificial heart pump was inserted into a patient without the need for surgery. The device provides temporary support for the heart muscle during the critical period after a heart attack or surgery.

A patient at Hammersmith Hospitals NHS Trust has become the first patient in the UK to receive a tiny device for the heart. Doctors at Hammersmith Hospital successfully placed the world's smallest heart support system, a 4mm-wide device, into the patient's heart by inserting it into an artery in the groin and passing it up into the heart along guide wires.

The pump assisted the patient's heart in the crucial few hours after coronary artery bypass surgery. The device offers hope for patients previously considered too ill to be operated on by providing temporary support for the heart muscle during the critical period after a heart attack or surgery.

The implanted pump sits in the left ventricle, the largest chamber of the heart. Despite its tiny size it can pump up to 2.5 litres of blood every minute. Because it is so small, it can be put in place without the need for any surgery. The pump uses an electrical motor connected to a 3mm wire which extends out of the patient, where it is connected to a battery and control pack the size of a small laptop computer. The pump can remain in place for up to five days.

"These devices are becoming increasingly cost-effective, especially when you consider the alternative to using them, which includes repeat invasive surgery and possibly transplant, and extended stays in hospital”, comments Mr Peter Smith, cardiac surgeon at Hammersmith Hospitals NHS Trust. "We have been astounded by how well this has worked, and have high hopes for the future of this technology.”
