Pulmonary Vein Stenosis Secondary to Surgical Correction of Mitral and Tricuspid Insufficiency due to Residual Atrial Septal Defect: Case Report

The use of a percutaneous catheter for device implantation is currently one of the most effective techniques for atrial septal defect closure. Occasionally, it may be poorly positioned or cause lesions to adjacent structures. Furthermore, several causes of pulmonary vein stenosis have been described, one of which being iatrogenic during cardiac surgical procedures. We present the case of a 41-year-old female patient with a history of atrial septal defect closure who presented with symptoms of stabbing chest pain, palpitations and functional class impairment. Physical examination showed no haemodynamic deterioration with systolic murmur in the pulmonary focus. Echocardiogram was performed identifying severe mitral regurgitation, moderate tricuspid regurgitation and residual atrial septal defect 11 years after defect closure. Surgery was performed to close the residual communication and mitral and tricuspid plasty. However, during the postoperative period the patient presented stenosis of the right pulmonary vein and was operated again to free the pulmonary veins with adequate clinical evolution at one year of follow-up.
