Summary: | No previous studies, either clinical or morphologic, have compared findings in patients with active infective endocarditis (IE) involving a previously stenotic versus a previously nonstenotic aortic valve. Clinical and cardiac necropsy findings were analyzed in 96 patients with active IE involving the aortic valve. Of the 96 patients, 25 (26%) had active IE superimposed on a previously stenotic aortic valve and 71 (74%) on a previously non-stenotic aortic valve. The patients with stenotic aortic valves compared with those with nonstenotic aortic valves had significantly higher mean ages (61 vs 47 years), a higher percentage >60 years of age (52 vs 24%), a higher percentage of men (92 vs 73%), a higher frequency of an absent or unknown predisposing factor to infection (68 vs 38%), a lower frequency of a precordial murmur of aortic regurgitation (44 vs 79%), a lower percent with a long duration (>60 days) of signs and symptoms of active IE (4 vs 23%), a larger mean heart weight (594 vs 514 g), a higher percentage with aortic valve calcific deposits (100 vs 24%), and a higher frequency of associated ring abscess (84 vs 52%). Thus, active IE superimposed on a stenotic aortic valve differs in some features compared with active IE on a nonstenotic aortic valve. Because ring abscess is so common when active IE involves a stenotic aortic valve in adults, operative intervention at an early stage may be warranted. |
