[Hemolysis after aortic valve replacement (author's transl)]. 1977

A Dörig, and M Rothlin, and B J Messmer

Hemolysis after isolated aortic valve replacement using Björk-Shiley and Starr-Edwards (series 1260) prostheses as well as unstented Fascia-lata valves has been determined in 50 patients. A battery of hemathologic and blood-chemical tests were performed in all patients but LDH has proved to be the most reliable parameter. Survival of erythrocytes was measured in a small group of patients. Patients with Björk-Shiley prosthesis have shown lower average rate of hemolysis (LDH 201 IU, Haptoglobin 45 mg %) than patients with Starr-Edwards prosthesis (LDH 273 IU, Haptoglobin 35 mg %). When functioning regularly neither prosthesis results, however, in clinically significant hemolysis. In patients with unstented Fascia-lata valve the degree of hemolysis reflects directly the functional status of the valve.

UI	MeSH Term	Description	Entries
D007770	L-Lactate Dehydrogenase	A tetrameric enzyme that, along with the coenzyme NAD+, catalyzes the interconversion of LACTATE and PYRUVATE. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist.	Lactate Dehydrogenase,Dehydrogenase, L-Lactate,Dehydrogenase, Lactate,L Lactate Dehydrogenase

D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.

D005206	Fascia Lata	CONNECTIVE TISSUE of the anterior compartment of the THIGH that has its origins on the anterior aspect of the iliac crest and anterior superior iliac spine, and its insertion point on the iliotibial tract. It plays a role in medial rotation of the THIGH, steadying the trunk, and in KNEE extension.	Fascia Latas,Lata, Fascia,Latas, Fascia
