    A 28-year-old pregnant lady presented with cardiomyopathy and atrial tachycardia. The patient had severe heart failure and syncope. Her past medical history was uneventful. Her mother, however, had received an implantable cardioverter defibrillator (ICD) after an out-of-hospital cardiac arrest due to idiopathic ventricular fibrillation. The patient was scheduled for programmed stimulation, during which a monomorphic ventricular tachycardia was induced. An ICD was then implanted. Following radiofrequency ablation of the atrial tachycardia, left ventricular function recovered completely. Given the family history, a genetic predisposition to both arrhythmias and tachycardiomyopathy needs to be considered.

    Cardiomyopathy I: Introduction and Classification01:25

    Cardiomyopathy I: Introduction and Classification

    Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

    Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

    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...

    Cardiomyopathy V: Interprofessional Care

    Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

    Pericarditis I: Introduction01:22

    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...
