Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

884
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Myocarditis I: Introduction01:21

Myocarditis I: Introduction

560
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...

Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

1.2K
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...

Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

932
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Rheumatic Heart Disease I: Introduction01:23

Rheumatic Heart Disease I: Introduction

834
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...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

982
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...

Area of Science:

  • Spinal pathology and imaging diagnostics
  • Biomedical research on pain mechanisms

Background:

  • Low back pain (LBP) is a leading cause of disability globally.
  • Modic changes on MRI are highly specific indicators of discogenic LBP.
  • Understanding Modic changes is crucial for effective LBP management.

Purpose of the Study:

  • To review the pathobiology of Modic changes.
  • To propose a disease model for Modic changes.
  • To highlight the clinical significance of Modic changes in LBP.

Main Methods:

  • Non-systematic literature review.
  • Analysis of pathogenetic factors and therapeutic approaches.
  • Synthesis of current research on Modic changes.

Main Results:

  • Modic changes involve inflammation, bone turnover, and fibrosis, likely representing stages of a single pathological process.
  • Disc/endplate damage and persistent inflammation are key factors in Modic change development.
  • Shared characteristics with osteoarthritic bone marrow lesions suggest roles for DAMPs and fat metabolism.

Conclusions:

  • Modic changes are a significant underlying pathology in LBP, not merely incidental findings.
  • Modic changes should be considered a potential therapeutic target.
  • Further research with new diagnostic tools and animal models is needed to clarify pathogenesis and improve treatment.
