Summary

A rare left atrial (LA) ball thrombus associated with mitral stenosis was observed to move freely within the heart. Anticoagulant therapy successfully resolved the thrombus before surgery.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Internal Medicine

Background:

  • Left atrial (LA) ball thrombus is a rare clinical finding.
  • Ball thrombi are typically associated with mitral stenosis, posing risks of systemic embolization or sudden death due to valve obstruction.

Purpose of the Study:

  • To report a case of a mobile left atrial ball thrombus in a patient with severe mitral stenosis.
  • To illustrate the diagnostic utility of echocardiography in visualizing such mobile thrombi.
  • To present the outcome following anticoagulant therapy.

Main Methods:

  • Echocardiography was used to diagnose and visualize the mobile left atrial ball thrombus.
  • The patient underwent a course of anticoagulant therapy.
  • Surgical exploration was performed after medical management.

Main Results:

  • Echocardiography clearly depicted a ball thrombus within the left atrium, exhibiting characteristic bouncing and rebounding movements against the atrial walls.
  • Following one month of anticoagulant therapy, the left atrial ball thrombus was no longer detected.
  • The thrombus was absent during subsequent surgical intervention.

Conclusions:

  • Mobile left atrial ball thrombi, though rare, can be effectively managed with anticoagulant therapy.
  • Echocardiography is crucial for diagnosing and monitoring these mobile thrombi.
  • This case highlights a successful non-surgical approach to managing left atrial ball thrombus in the context of mitral stenosis.
