  • Title: The long-term outlook for valve replacement in active endocarditis.
    Author: Wilcox BR, Murray GF, Starek PJ.
    Journal: J Thorac Cardiovasc Surg; 1977 Dec; 74(6):860-3. PubMed ID: 926813.
    Abstract:
    This study follows the clinical course of 22 patients in the active phase of infective endocarditis who inderwent valve replacement at North Carolina Memorial Hospital between March, 1966, and March, 1976. At the time of operation, there was gross valve tissue destruction in 16 patients, verrucae in nine, ruptured chordae tendineae in five, and myocardial or annular abscess formation in five. Four patients survived less than 6 months after the initial operation. One survived almost 3 years before dying of recurrent carcinoma of the lung. The remaining 17 patients have been followed an average of 4.6 years. Major postoperative complications were as follows: paravalvular problem, five patients; congestive heart failure, seven patients; complete heart block, three patients; systemic arterial emboli, four patients. These complications often were associated with the preoperative presence of annular or myocardial abscess. Thus it appears that postoperative complications often result from annular structural deficiencies rather than being directly related to active infection.
