A young man experienced a type A aortic dissection, possibly linked to sildenafil use. This rare event highlights potential risks, especially with underlying aortic conditions like bicuspid aortic valve.
Area of Science:
- Cardiology
- Vascular Surgery
- Pharmacology
Background:
- Aortic dissection is a life-threatening condition involving a tear in the aorta's inner layer.
- Sildenafil, a phosphodiesterase type 5 inhibitor, is commonly used for erectile dysfunction.
- Literature reports of sildenafil-associated aortic dissection are exceedingly rare.
Observation:
- A 28-year-old male presented with type A aortic dissection.
- The patient had a history of bicuspid aortic valve and ascending aortic aneurysm.
- Sildenafil use was noted prior to the event.
Findings:
- This case represents a potential association between sildenafil use and type A aortic dissection.
- Literature review revealed only two other similar cases, one type A and one type B dissection.
- The patient's pre-existing bicuspid aortic valve and aneurysm are significant contributing factors.
Implications:
- This case underscores the importance of considering medication history in patients with aortic dissection.
- Further research is needed to establish a definitive link between sildenafil and aortic dissection.
- Awareness of potential risks is crucial for both clinicians and patients, especially those with underlying cardiovascular conditions.

Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...
