Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

305
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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

141
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 I: Introduction01:22

Mitral Stenosis I: Introduction

192
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...

Heart Failure III: Clinical Manifestations

254
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

Pulmonary Embolism III: Nursing Management

161
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

2.0K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Summary

Echocardiography in pulmonary embolism (PE) can identify right ventricular strain, predicting the need for advanced intervention. Left ventricular dysfunction independently predicts 30-day mortality in high-risk PE patients.

Area of Science:

  • Cardiology
  • Emergency Medicine
  • Radiology

Background:

  • Risk stratification is crucial for managing patients with pulmonary embolism (PE).
  • Guiding advanced interventional strategies and patient disposition requires accurate risk assessment.

Purpose of the Study:

  • To evaluate echocardiographic markers of right ventricular (RV) strain and left ventricular (LV) function in high-risk PE.
  • To determine the association of these markers with the need for advanced intervention and 30-day mortality.

Main Methods:

  • Retrospective analysis of emergency department (ED) patients with PE requiring pulmonary embolism response team activation.
  • Cardiac point-of-care ultrasound assessed for septal bowing, RV hypokinesis, McConnell sign, RV enlargement, and LV systolic dysfunction.
  • Outcomes included advanced intervention and 30-day mortality.

Main Results:

  • Septal bowing, RV enlargement, and McConnell sign were associated with the need for advanced intervention in PE patients.
  • Left ventricular dysfunction was the sole significant predictor of 30-day mortality (OR 9.63).

Conclusions:

  • Sonographic RV strain findings (septal bowing, McConnell sign, RV enlargement) correlate with advanced intervention needs in ED PE.
  • Left ventricular dysfunction predicts higher 30-day mortality in PE patients.
  • These echocardiographic findings aid ED management and disposition decisions for PE.
