Stroke Volume Analysis During Aortic Valve Replacement Trial (standart)
2014年8月7日 更新者:Michael Sander、Charite University, Berlin, Germany
Compromised peripheral tissue oxygenation during surgery may lead to worse patient outcome, mainly due to post-operative infections or heart failure.
Insufficient stroke volume and/or cardiac output due to hypovolemia or cardiac defects play a central role in causing poor peripheral tissue oxygenation.
In order to assess stroke volume, there are numerous invasive and non-invasive methods available.
Up to the present date it is unknown, if these methods may by used interchangeably in patients with severe cardiac defects like aortic stenosis.
