Why the study?
Cardiac papillary fibroelastoma is a rare, benign tumour that can lead to life-threatening complications such as myocardial ischemia.
A papillary fibroelastoma of the aortic valve can present as an acute coronary syndrome with transient ST segment elevation and should be considered when coronarography is normal.
No takes yet. Share an insight, caveat, or question.
Fibroelastoma may cause ACS with normal coronaries; this case extends the differential but leaves open systematic study.
Makani et al. (2022) studied this question.
