Pulmonary Embolism I: Introduction

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...

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...

Acute Coronary Syndrome III: Diagnostic Studies

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Venous Thrombosis I: Introduction

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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Summary

Even mild COVID-19 can cause serious blood clots, including right atrial thrombi, even in vaccinated individuals. Early diagnosis and anticoagulation are key for managing these cardiovascular complications.

Background:

Coronavirus disease 2019 (COVID-19) is a global health crisis associated with significant morbidity and mortality.
A notable complication of COVID-19 is a hypercoagulable state, increasing the risk of cardiac thrombi and venous thromboembolism (VTE).
Existing research primarily links severe COVID-19 to thromboembolic events, with less focus on milder cases or vaccinated individuals.

Observation:

A case report details an 85-year-old male diagnosed with a large right atrial (RA) thrombus in transit.
The diagnosis was incidental, occurring two weeks after a mild COVID-19 infection in a fully vaccinated patient.
Computed tomography with angiography revealed acute pulmonary thromboembolic disease with a substantial clot burden and signs of right heart strain.

Findings:

Right atrial (RA) thrombi and VTE can manifest even after mild COVID-19 infection.
These thromboembolic events are possible in patients who have completed their COVID-19 vaccination series.
The patient, despite the large clot burden, remained hemodynamically stable and was successfully treated with anticoagulation.

Implications:

This case highlights that mild COVID-19 and vaccination do not preclude the risk of significant thromboembolic events.
Echocardiography is identified as a valuable diagnostic tool for evaluating RA thrombi in this patient demographic.
Clinicians should maintain a high index of suspicion for VTE and cardiac thrombi in patients recovering from COVID-19, regardless of disease severity or vaccination status.
