A small ventricular septal defect (VSD) in a 41-year-old man led to aortic aneurysms and dissection. Early VSD closure may prevent adult degenerative vascular changes.

Area of Science:

  • Cardiovascular Medicine
  • Pathology

Background:

  • A small perimembranous ventricular septal defect (VSD) is often considered hemodynamically benign.
  • Such defects typically do not warrant surgical intervention due to their size and lack of pulmonary complications.

Observation:

  • A 41-year-old male presented with aortic elongation, tortuosity, dissecting aneurysm, and aneurysms.
  • These vascular complications were associated with a previously asymptomatic, small perimembranous VSD.

Findings:

  • Prolonged strenuous physical activity may have accelerated aortic sclerosis and vascular lesions secondary to the VSD.
  • A specific injury might have triggered mural dissection in a weakened aortic wall.

Implications:

  • Clinicopathological analysis suggests early VSD closure could prevent premature degenerative vascular and valvular changes in adulthood.
