Key Points

  • To investigate the mechanism behind a reversible complete atrioventricular block caused by rupture of the left coronary aortic sinus.
  • Identifying the rupture of the sinuses of Valsalva.
  • Assessing the formation of a hematoma around the central fibrous body.
  • Examining the effects on the atrioventricular node region.
  • Complete atrioventricular block was observed.
  • Mechanical compression from the hematoma was confirmed as the cause.
  • The block was reversible following treatment.

Abstract

Spontaneous rupture of the sinuses of Valsalva and the resultant hematoma extending around the central fibrous body can cause a reversible complete atrioventricular block by mechanical compression of the atrioventricular node region.
