This case report concerns a young woman who, during her pregnancy, suffered severe mitral regurgitation. It was discovered at the same time that she had a left atrial myxoma. During the early postpartum period she successfully underwent an anterior minithoracotomy to remove the left atrial myxoma in conjunction with repair of the mitral valve. The thoracotomy approach in this specific patient was chosen as it would give a better chance of successful mother-child bonding because the patient would be able to avoid the precautions which would have been necessary following a sternotomy, especially the limitation of her ability to hold her child during the first 4–6 weeks postoperatively.
