Aortic Non-coronary Cusp Perforation Following Methicillin-Sensitive Staphylococcus aureus (MSSA) Endocarditis

Area of Science:

• Cardiology
• Infectious Diseases
• Cardiac Surgery

Background:

• Bacterial endocarditis can lead to serious cardiac complications.
• Perforation of the aortic valve, particularly the noncoronary cusp (NCC), is a rare but significant sequela.

Observation:

• A 62-year-old male, post-recovery from Methicillin-sensitive Staphylococcus aureus (MSSA) endocarditis, presented with worsening cardiac symptoms.
• Despite completing antibiotic treatment, the patient developed severe aortic insufficiency.

Findings:

• The cause of aortic insufficiency was identified as an isolated perforation of the aortic valve's noncoronary cusp (NCC).
• This perforation occurred as a late-onset complication following the initial endocarditis episode.

Implications:

• This case emphasizes the critical need for diligent long-term cardiac monitoring in patients with a history of endocarditis.
• Vigilant follow-up is essential to identify and manage potentially severe, delayed complications such as aortic valve perforation and insufficiency.
