Partial anomalous pulmonary venous connection with acquired valve disease.

We describe the rare case of a 76-year-old man with left partial anomalous pulmonary venous connection with intact atrial septum. He experienced dyspnea due to significant aortic stenosis and mitral regurgitation, and required valve repair. Preoperative computed tomography revealed connection of the left upper pulmonary vein to the innominate vein. Although right heart overload was not recognized, we repaired the left partial anomalous pulmonary venous connection with concomitant aortic valve replacement and mitral annuloplasty, because of the potential for unpredictable harmful effects of a residual left-to-right shunt. The patient recovered well with no signs of left upper lung congestion.
