Abstract

This paper reports the early results of combined aortic and mitral valve replacement in 39 patients, who underwent operation with the convexo-concave Björk-Shiley prosthesis. There were no intra-operative deaths. Two patients (5%) died while in hospital of myocardial failure and left ventricular rupture, respectively. One late death (3%) was due to a thrombosis of the mitral prosthesis (N.Y.H.A. class IV at operation). Cumulative follow-up (2-31 months) was 100%. One patient had radial artery embolization while converting to atrial fibrillation. Another patient required repair of an aortic paraprosthetic leakage. Clinical improvement (N.Y.H.A.) was noted in 15/19 re-examined patients (79%). Average heart volume decreased (p less than 0.05) and Maximal working capacity increased (p less than 0.05) after valve replacement. Seven patients (7/19) converted to sinus rhythm after operations and one (1/19) developed atrial arrhythmia. Haemolysis was generally mild and without signs of anaemia. The overall thrombo-embolic rate (5.9% per year) remained thus far the same as that encountered with the standard model prosthesis in combined aortic and mitral valvular disease.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
