Abstract

The surgical closure of VSD in patient with severe pulmonary hypertension has been considered a difficult problem for surgeons, because sudden hemodynamic change after closure of the defect could bring on high perioperative mortality. Recently, it was reported that UVP (unidirectional valve patch), which allows some blood to flow from right to left in case of acute right heart failure, is effective in improving the postoperative hemodynamics after closing septal defects. This 42-year old woman had suffered from VSD for 20 years and recently complained of worsening exertional dyspnea for three months, and was diagnosed of a large VSD (2.0 cm in diameter) with severe pulmonary hypertension (116/38 mm Hg), equal to systemic arterial pressure. We could successfully close VSD with severe pulmonary hypertension using one UVP and the other UVP for the creative ASD to be prepared against possible acute right heart failure. She was discharged on the fourteenth postoperative day and has been well for twelve months with spontanenous closure of UVP patch at the ninth postopeative month.
