Influence of etiology on the functional result of aortic valve replacement
Abstract:
The functional result of aortic valve replacement has been assessed in patients treated for isolated aortic incompetence. Using maximal oxygen uptake as an index of myocardial function, a significant difference (p less than .05) exists between the patients who had Q fever endocarditis on the one hand and those who had bacterial endocarditis or rheumatic fever on the other hand. We believe that permanent myocardial damage occurs as a result of bacterial endocarditis and rheumatic fever but because of the biological properties of Coxiella burnetii the myocardium is spared in Q fever endocarditis.
