- Abstract: An 83-year-old woman (BSA 1.36 m2) who had undergone aortic valve replacement (Magna ease 19 mm), mitral valve replacement (Epic mitral 25 mm), tricuspid annuloplasty (De Vega technique), and pulmonary vein isolation eight years earlier was referred to our hospital due to her heart failure symptoms. Ultrasound cardiography revealed severe mitral regurgitation due to perforation of bioprosthetic valve, severe mitral valve stenosis (mean pressure gradient 7.8 mmHg) due to bioprosthetic deterioration, and subsequent pulmonary hypertension (mean pulmonary artery pressure 49 mmHg, tricuspid regurgitation pressure gradient 85.5 mmHg). We performed a redo aortic valve (Inspiris 23 mm) and mitral valve (Epic mitral 29 mm) replacement using the Manouguian technique. The postoperative course was uneventful and pulmonary hypertension improved (tricuspid regurgitation pressure gradient 39.6 mmHg).
