Comparative StudyRestraint to the left ventricle alone is superior to standard restraint.
In standard ventricular restraint therapy, a single level of restraint is applied to the entire ventricular surface. We showed previously that at high restraint levels, cardiac tamponade develops because of the thin-walled right ventricle, even while the left ventricle remains unaffected. We now hypothesize that applying restraint exclusively to the left ventricle permits higher levels of restraint, resulting in increased benefit to the left ventricle. ⋯ We showed previously that, with standard restraint, right ventricle tamponade develops at high restraint levels, limiting restraint therapy. We now show that restraint applied to the left ventricle alone permits increased restraint levels, without causing right ventricle or left ventricle tamponade, for greater therapeutic benefit. We conclude that partial left ventricle restraint may be more effective than standard restraint.

Effect of preoperative renal function on long-term survival after cardiac surgery.
The study objective was to investigate the effect of renal failure on intermediate-term survival in cardiac surgery patients. ⋯ The results of our study have shown that preoperative renal dysfunction is an independent predictor of long-term mortality in cardiac surgery patients.
