“…There have been several reports of valve replacement for acute aortic incompetence after bacterial endocarditis (Wallace, Young and Osterhout, 1965;Windsor and Shanahan, 1967;Wise et al, 1971) but few after acute mitral incompetence (Robicsek et al, 1967;Yacoub et al, 1972;English, Honey and Clelland, 1972). Urgent double valve replacement after acute bacterial endocarditis is, however, rare (Windsor and Shanahan, 1967;Kretschmer and Lawrence, 1969;Gonzalez-Lavin, Wise and Ross, 1971).…”
