Insights

Left ventricular noncompaction (LVNC), a rare cardiomyopathy, often presents late. This case highlights a 23-year-old female with LVNC, coexistent cardiac defects, and sinus node dysfunction presenting with dizziness.

Area of Science:

  • Cardiology
  • Genetics
  • Internal Medicine

Background:

  • Left ventricular noncompaction (LVNC) is a rare, genetically diverse cardiomyopathy.
  • Symptoms like dyspnea and arrhythmias often lead to late diagnosis in adulthood.
  • Symptomatic sinus node dysfunction is an uncommon presentation of LVNC.

Purpose of the Study:

  • To report a rare case of adult-onset LVNC.
  • To highlight unusual coexistent cardiac defects in an adult LVNC patient.
  • To emphasize atypical initial presentation of LVNC.

Main Methods:

  • Case report of a 23-year-old female patient.
  • Review of clinical presentation, echocardiography, and cardiac history.
  • Analysis of coexistent cardiac anomalies and sinus node function.

Main Results:

  • The patient presented with dizziness due to persistent sinus node dysfunction.
  • Diagnosed with LVNC, patent ductus arteriosus, and bicuspid aortic valve.
  • Demonstrated a rare combination of isolated LVNC with congenital heart defects in adulthood.

Conclusions:

  • LVNC can present atypically in adulthood with sinus node dysfunction and congenital defects.
  • Early diagnosis and management are crucial for patients with LVNC.
  • This case expands the understanding of LVNC's varied clinical manifestations.

Cardiomyopathy II: Dilated Cardiomyopathy01:30

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 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...

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

ECG Interpretation of Arrhythmias I: Sinus Arrhythmias

Arrhythmias are disturbances in the heart's rhythm that lead to abnormal heartbeats. These irregularities can originate from different parts of the heart and are classified based on their origin and nature.
Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism, and...
Mechanism of Cardiac Arrhythmias01:28

Mechanism of Cardiac Arrhythmias

Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.
Mitral Stenosis I: Introduction01:22

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...
