Abstract

Native aortic valve thrombosis is a very rare condition. We report a case of ST-segment elevation acute myocardial infarction secondary to native aortic valve thrombus in a 61-year-old woman who presented with acute chest pain. The patient had no previous precipitating factors. The patient was treated with a thrombolytic agent and subsequently recovered. On a follow-up echocardiogram, the thrombus of aortic valve disappeared.

Figure

• 

  Fig. 1 An electrocardiogram recorded in the emergency room shows an inferior myocardial infarction.

• 

  Fig. 2 Transthoracic echocardiography. Parasternal short (A) and long (B) axis views demonstrate a round echogenic mass (arrow) attached to the right coronary artery orifice of the right coronary cusp.

• 

  Fig. 3 A chest CT image shows a round mass (arrow) at the aortic valve.

• 

  Fig. 4 Follow-up echocardiography. Two days after the incident the thrombus reduced in size and changed in shape (A). Twelve days later, the thrombus was completely resolved (B).

• 

  Fig. 5 A right coronary angiogram shows residual thrombosis (arrows) without significant stenosis.
