A 45-year-old female patient, Jehovah's Witness, was diagnosed with Lutembacher syndrome, New York Heart Association (NYHA) class IV congestive heart failure (CHF) and severe malnutrition. Echocardiogram showed an ostium secundum atrial septal defect, 38 mm in diameter, mitral valve area of 0.5 cm², Wilkins score of 10, severe pulmonary hypertension, estimated systolic pressure of 96 mmHg, right ventricle with significant dilation and severe dysfunction and severe tricuspid valve insufficiency. Despite optimal clinical treatment, there was no improvement of CHF or the patient's overall condition, which led to a change in the initial conduct of surgical treatment to a two-stage therapy, starting with balloon mitral valvotomy, as a bridge to surgery. Postoperative mitral valve area increased to 1.34 cm². The patient evolved with significant clinical improvement, and surgery was performed 120 days later with mitral valve replacement by a mechanical valve and atrioseptoplasty using a bovine pericardial patch in addition to tricuspid valve cerclage. Patient was discharged 11 days after the surgery and is currently on the sixth postoperative month, evolving with clinical stability and improvement in quality of life.
