Summary
Tuberculosis (TB) may cause acquired right atrial appendage aneurysm (RAAA), a rare condition. Surgical removal and TB treatment led to a full recovery, highlighting the importance of considering infections in RAAA.
Area of Science:
- Cardiology
- Infectious Diseases
- Pathology
Background:
- Right atrial appendage aneurysm (RAAA) is typically congenital, caused by myocardial defects.
- Acquired causes, especially infectious/inflammatory conditions, are less understood.
Purpose of the Study:
- To investigate a potential acquired mechanism for RAAA.
- To highlight tuberculosis (TB) as a possible contributing factor.
Main Methods:
- Case report of a patient with pulmonary TB and RAAA.
- Clinical presentation, histopathological examination of excised tissue.
- Surgical management and postoperative follow-up.
Main Results:
- Histopathology confirmed RAAA and suggested an infectious etiology linked to TB.
- Surgical excision and anti-tubercular therapy resulted in an uneventful recovery.
- No recurrence or complications observed during follow-up.
Conclusions:
- This case broadens RAAA etiology to include infectious causes like TB.
- Histopathology is crucial for diagnosis and understanding pathogenesis.
- Vigilant postoperative surveillance is essential for optimal outcomes.

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...
01:22Aortic 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...
01:21Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
01:29Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

01:28Pulmonary Tuberculosis II
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

01:15Aortic Regurgitation I: Introduction
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
