Summary

Patent foramen ovale (PFO), common but often silent, can cause severe hypoxic respiratory failure when right heart pressures rise. This case highlights PFO closure as a resolution for refractory hypoxia due to constrictive pericarditis.

Pericarditis III: Medical Management

The primary objectives of managing pericarditis are to determine the underlying cause, provide effective therapy for treatment and symptom relief, and promptly detect signs and symptoms of cardiac tamponade. The following outlines the essential aspects of medical management for pericarditis:ObjectivesDetermine the Cause: Identifying the underlying cause of pericarditis is crucial for targeted treatment. Causes include viral infections, autoimmune diseases, post-cardiac injury syndrome, and...

Mitral Stenosis I: Introduction

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...

Pericarditis I: Introduction

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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
