[Aortic valve replacement through right thoracotomy; report of a case].
A 78-year-old female was admitted to our hospital with a diagnosis of severe aortic valve regurgitation. She had had dyspnea on effort and syncope twice in 5 months. She had also suffered from right pneumonia 8 years before, and her respiratory function was severely constrictive. Chest X-ray showed her mediastinum significantly shifted toward the right side. Chest computed tomography (CT) revealed the main pulmonary artery, right atrium (RA) and right pulmonary veins also shifted toward the right. We planned right thoracotomy at 4th intercostals space to obtain a good surgical field. A cardiopulmonary bypass was established by RA appendage drainage and femoral artery perfusion. Aortic valve replacement(AVR) was performed successfully after aortic clamp. Though defibrillator pads were placed on her back and the anterior wall of the left chest during operation, no ventricular fibrillation occurred. AVR via right thoracotomy is considered to be a good option for such a mediastinum shifted case.
