Multiple cardiac anomalies in an elderly man with Klinefelter's syndrome.

We report a case of an elderly man with Klinefelter's syndrome and multiple cardiac defects, including partial anomalous pulmonary venous connection, atrial septal defect and pulmonary arterial hypertension. To the best of our knowledge, partial anomalous pulmonary venous connection in association with Klinefelter's syndrome has never been described in the literature. This anomalous pulmonary connection was a serendipitous discovery following the malpositioning of a peripherally inserted central catheter.
