[Bronchial cyst in the endocardium of the left heart. Case report with review of cardiac heterotopic tissues].

Connatal heterotopies are rare accidental findings fore-most without clinical symptoms. The present case report describes an asymptomatic multilocular bronchial cyst of a 72 years old woman which occurred in the left ventricular endocard of the anterior papillary muscle and which was covered with ciliated and occasionally multilayered epithelium. Today the knowledge about these rare cardial heterotopies is important, because they are not only accidental postmortal findings but also the clinical importance is rising as consequence of the improved diagnostic imaging procedures with a high resolution. The histogenesis and the classification of cardial heterotopies is discussed.
