Summary
A patient with Eisenmenger patent ductus arteriosus (PDA) experienced a pulmonary trunk dissection. This serious condition, involving a flap in the pulmonary artery, was confirmed by CT scan.
Area of Science:
- Cardiology
- Vascular Surgery
- Medical Imaging
Background:
- Eisenmenger syndrome is a rare condition arising from a large left-to-right cardiac shunt, leading to pulmonary hypertension.
- Patent ductus arteriosus (PDA) is a congenital heart defect where the ductus arteriosus fails to close after birth.
- Pulmonary trunk dissection is a rare and life-threatening condition involving a tear in the wall of the main pulmonary artery.
Observation:
- A 49-year-old female patient with a known history of Eisenmenger PDA underwent a transthoracic echocardiogram.
- The echocardiogram revealed clear evidence of dissection within the pulmonary trunk.
- A flap was observed extending across the pulmonary trunk lumen.
Findings:
- Transthoracic echocardiography identified a pulmonary trunk dissection.
- Computed tomography (CT) scan confirmed the presence of the dissection and the intimal flap.
- The findings highlight a rare complication in a patient with complex congenital heart disease.
Implications:
- Pulmonary trunk dissection in the context of Eisenmenger PDA represents a critical diagnostic and management challenge.
- Prompt and accurate diagnosis using multimodal imaging (echocardiography and CT) is crucial for patient outcomes.
- This case underscores the importance of vigilant monitoring for vascular complications in patients with severe pulmonary hypertension and congenital heart disease.

01:29Pulmonary 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...
01:19Pulmonary Embolism I: Introduction
A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
01:29Pulmonary 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...
01:22Aortic 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...
01:18Pulmonary Edema II: Pathophysiology
Pulmonary edema is the accumulation of fluid in the interstitial and alveolar spaces of the lungs, impairing gas exchange and oxygen delivery. It may be cardiogenic or noncardiogenic, but both reduce oxygenation and lung compliance.Cardiogenic Pulmonary EdemaCardiogenic edema results from increased hydrostatic pressure in pulmonary capillaries, usually due to left ventricular dysfunction from myocardial infarction, heart failure, or valvular disease. Ineffective cardiac pumping causes blood to...
01:30Pulmonary Hypertension: Classification and Pathogenesis
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...
