Rheumatic Heart Disease I: Introduction

3
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Pericarditis II: Clinical features and Diagnostic Tests

3
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

7
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Myocarditis I: Introduction

2
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

3
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...

Pericarditis I: Introduction01:22

Pericarditis I: Introduction

2
Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Pathology

Background:

  • Subepicardial hematoma resulting from spontaneous coronary artery rupture (SCAR) is an exceptionally rare clinical occurrence.
  • The case involved an asymptomatic 68-year-old woman with a history of Graves' disease, presenting with an abnormal right hilar shadow on imaging.
  • The patient had no history of chest trauma or conditions typically associated with coronary artery rupture.

Purpose of the Study:

  • To report a rare surgical case of organized subepicardial hematoma.
  • To highlight the diagnostic challenges and surgical management of SCAR-induced hematoma.
  • To discuss the potential association of underlying conditions with SCAR.

Main Methods:

  • Computed tomography (CT) revealed a 44-mm mass lesion anterior to the right atrium, with feeding vessels arising from the proximal right coronary artery.
  • The patient underwent radical surgical resection of the mass.
  • Surgical removal was performed using an ultrasonic scalpel.

    • Main Results:

    • The resected lesion was identified as an organized subepicardial hematoma.
    • Complete surgical removal of the hematoma was achieved.
    • Graves' disease was not identified as an underlying cause of the SCAR.

    Conclusions:

    • This case represents a rare surgical instance of organized subepicardial hematoma secondary to SCAR.
    • A high index of clinical suspicion is crucial for accurate diagnosis of such rare conditions.
    • Graves' disease is unlikely to be an underlying factor in this specific case of SCAR.
