Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

177
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

72
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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Mitral Stenosis II: Clinical features and Diagnostic Tests01:23

Mitral Stenosis II: Clinical features and Diagnostic Tests

44
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Coronary Circulation01:21

Coronary Circulation

4.8K
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...

Chambers of the Heart01:16

Chambers of the Heart

6.3K
The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.
Deoxygenated blood from the body is received in the right...

Summary

A large, mobile left atrial thrombus was observed in a patient with a mechanical mitral prosthesis. This ping-pong ball-like mass moved precariously near the prosthesis, posing a significant embolic risk.

Area of Science:

  • Cardiology
  • Medical Imaging

Background:

  • Transesophageal echocardiography (TEE) is crucial for cardiac imaging.
  • Mechanical mitral prostheses require careful monitoring for complications.

Observation:

  • A 69-year-old woman presented with a mobile, 4 cm left atrial thrombus.
  • The thrombus exhibited unusual "ping pong ball"-like movement within the left atrium.
  • A separate thrombus was noted in the left atrial appendage.

Findings:

  • The mechanical mitral prosthesis was functioning normally.
  • The mobile left atrial thrombus interacted dynamically with the mitral regurgitant jet.
  • The thrombus moved towards the mitral valve orifice but was repelled.

Implications:

  • Mobile left atrial thrombi pose a high risk of systemic embolism.
  • Echocardiographic findings highlight the potential for thrombus-valve interaction.
  • This case underscores the importance of vigilant monitoring in patients with cardiac thrombi and prostheses.
