Key result
Cardiac sarcoidosis can involve the papillary muscle and manifest as conduction system dysfunction, ventricular arrhythmias, congestive cardiac failure, or sudden cardiac death.
Case Report
This case report describes a presentation of cardiac sarcoidosis involving the papillary muscle.
Raises awareness of papillary muscle involvement in cardiac sarcoidosis; extends phenotypic spectrum but leaves open prevalence and management questions.
Sarcoidosis is a granulomatous multisystem disease that is thought to arise from a dysregulated immunological response. A total of 25% of those suffering from sarcoidosis have cardiac involvement on postmortem analysis, but it is clinically apparent in only 5%.1 Isolated cardiac sarcoidosis (CS) has also been described.2 It may manifest as conduction system dysfunction, ventricular arrhythmias, congestive cardiac failure, or sudden cardiac death.3 CS has a predilection for the ventricular myocardium and its clinical presentation may vary from no symptoms to sudden cardiac death.
