Аннотация
BACKGROUND: Intramyocardial dissection and sinus of Valsalva aneurysm are both rare cardiac conditions that could complicate cardiac surgical interventions.
CASE SUMMARY: We report a unique case of a young man with multiple episodes of syncope who was diagnosed with both intramyocardial dissection and sinus of Valsalva aneurysm a few months after mechanical aortic valve replacement. The patient subsequently died.
DISCUSSION: The accurate diagnosis of this complex disease was possible by using multiple noninvasive cardiac imaging techniques, including echocardiography and computed tomography scan. The association of both complications could suggest an underlying condition such as connective tissue disease. Intramyocardial dissection can be responsible for several complications, including sudden death.
TAKE-HOME MESSAGES: Intramyocardial dissection is a rare and life-threatening condition. Its association with sinus of Valsalva aneurysm is exceptional. Both conditions could complicate cardiac surgery and require a multimodality imaging-based approach for an accurate diagnosis.
