Background:
Factor XII- is an important part of coagulation cascade. Its deficiency is benign but has been rarely associated with myocardial infarction and venous thrombosis.
Case Presentation:
We present a case of a young lady who presented with pulmonary embolism after supraventricular arrhythmia ablation. She was later found out to have factor XII deficiency. Her treatment course with rivaroxaban was uncomplicated and she stayed well afterwards.
Conclusion:
This report adds to the growing evidence of possible not-so-benign nature of factor XII deficiency.
