Diagnosing coronary artery paradoxical embolism is rare. This case confirms myocardial infarction from a proven paradoxical coronary embolism via a patent foramen ovale, highlighting echocardiography

Area of Science:

  • Cardiology
  • Vascular Medicine
  • Diagnostic Imaging

Background:

  • Paradoxical embolism in the coronary artery is a rare clinical diagnosis.
  • Diagnosis is often presumptive, based on specific criteria.
  • A "proven" diagnosis requires visualizing the embolus within an abnormal venous-arterial communication.

Observation:

  • This paper reports a case of myocardial infarction.
  • The infarction was caused by a proven paradoxical coronary embolism.
  • The embolism occurred through a patent foramen ovale.

Findings:

  • Echocardiography, particularly trans-esophageal echocardiography, is crucial for diagnosis.
  • Early echocardiographic examination after presentation aids in diagnosis.
  • This case provides definitive evidence of coronary paradoxical embolism.

Implications:

  • This case underscores the importance of considering paradoxical embolism in specific clinical scenarios.
  • Early and accurate diagnosis via echocardiography can improve patient outcomes.
  • Further research into the diagnostic and therapeutic strategies for paradoxical embolism is warranted.

Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Coronary Circulation01:21

Coronary Circulation

The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
