Noncompaction of the myocardium coexistent with bronchiectasis and polycystic kidney disease.

Noncompaction of the ventricular myocardium (NCM) is a disorder of unknown aetiology characterised by numerous, prominent ventricular trabeculations and deep intertrabecular recesses. Polycystic kidney disease (PKD) is characterised by the formation of multiple cysts in the kidneys and liver and, less frequently, in the pancreas. Cardiovascular abnormalities in PKD involve hypertension, mitral valve prolapse, intracranial aneurysms and pulmonary abnormalities include primary ciliary dyskinesia and bronchiectasis. Several case reports have described the possible association between PKD and NCM. However, NCM, PKD and bronchiectasis have not previously been correlated. This is the first case of NCM coupled with PKD and bronchiectasis.
