2. Fig 1
(A) Vegetation and abscess located in the posteromedial commissure of the mitral valve. (B) Radical debridement of the infected annulus and adjacent leaflets resulted in a large defect in the mitral valve orifice. The annular defect was patched with pericardium. (C) The leaflet remnants were approximated at the leading edge with a horizontal mattress suture to form a zone of apposition (inset). The residual D-shaped defect between the mitral annular patch and apposed leaflets was closed with a pericardial patch, thus restoring valve competence.

3. Fig 2
(A) Incompetent and dilated tricuspid valve after excision of the septal leaflet and one third of the anterior leaflet. The ventricular septal defect was patched with pericardium. (B) The inferior leaflet and remnant of the anterior leaflet were approximated with a horizontal mattress suture to form a zone of apposition (inset). The residual D-shaped defect between the dilated tricuspid annulus and apposed leaflets was patched with pericardium to produce a competent valve. (C) An annuloplasty ring was inserted to reduce the size of the tricuspid annulus.
