Brief Summary:
The purpose of this study is to investigate the incidence and predictive factors related to intestinal injury in patients undergoing heart valve replacement through a multicenter study in China.

Condition or disease
Injury of Other and Multiple Parts of Small Intestine

Detailed Description:
Intestinal injury is one of main reasons for mobidity and mortality after heart valve replacement, but its incidence and potential risk factors remain unclear. A multicenter study in China is undertaken to investigate the incidence and predictive factors related to intestinal injury in patients undergoing heart valve replacement.
