II-7 Studies for early postoperative complications in valve replacement

Early Postoperative Anticoagulation by Enoxaparin after Mechanical Aortic Valve Replacement

Background: The use of low molecular weight heparin for early anticoagulation after mechanical aortic valve replacement is still a matter of debate even more that the early postoperative phase is associated with maximum of thrombo-embolic and bleeding risks. The objective of this study is to verify the efficacy and the safety of low molecular weight heparin for the early anticoagulation after m...

Long-term complications of valve replacement.

Postoperative serum troponin T concentration in patients undergoing aortic valve replacement does not predict early postoperative outcome.

BACKGROUND The measurement of serum cardiac troponin T concentration (cTnT) after aortic valve replacement (AVR) provides the opportunity to assess the degree of myocardial damage and may have some prognostic value. AIM To determine whether elevated troponin level is related to patient outcome. METHODS We investigated patient outcome and postoperative serum concentration of troponin T in 79...

Arterial hypertension in immediate postoperative period after valve replacement.

Paroxysmal hypertension occurred during the first 8 hours after cardiac valve replacement in 15 of 186 consecutive patients. The clinical characteristics of this hypertension were similar to those of hypertension after myocardial revascularization, except that this complication occurred much less frequently after valve replacement (8.1%) than after myocardial revascularisation (33%) (P less tha...

Aortic valve replacement in octogenarians: outcome and predictors of complications.

INTRODUCTION We aimed to evaluate the outcome in octogenarians after aortic valve replacement (AVR) and to determine the perioperative parameters that were predictive of a complicated postoperative course. METHODS The study population included 304 patients (65% male) aged 82.7 ± 3.5 years who underwent AVR alone (63%), in combination with coronary artery bypass grafting (28%) or with other pr...
