Midterm results of diagnostic treatment and repair strategy in older patients presenting with nonrestrictive ventricular septal defect and severe pulmonary artery hypertension

Abstract

There were no operative deaths. SPO2 and baseline six-minute walk test (SMWT) distance of all selected patients increased significantly and mean pulmonary artery pressure (MPAP) regressed significantly after diagnostic treatment and at late follow-up (P < 0.01). The incidence of late postoperative PAH was seen in six (10.7%) patients and by Logistic regression analysis, early postoperative PAH was an independent risk factor related to late postoperative PAH CONCLUSIONS: Diagnostic treatment and repair strategy was effective and safe for treatment of nonrestrictive VSD and SPAH and the midterm results were excellent. Diagnostic treatment strategy was effective in assessing the reversibility of SPAH in older patients associated with nonrestrictive VSD and the PVD in these selective patients is generally reversible.
