Summary
Left ventricular noncompaction (LVNC) cardiomyopathy is increasingly diagnosed. This study reports 9 cases, with heart failure being the most common presentation and beta-blockers proving useful in management.
Area of Science:
- Cardiology
- Cardiovascular Imaging
- Internal Medicine
Background:
- Advances in cardiac imaging have increased left ventricular noncompaction (LVNC) diagnoses.
- LVNC can present asymptomatically or with severe complications like heart failure, arrhythmias, and thromboembolism.
- Diagnosis is typically via echocardiography, with cardiac MRI offering higher resolution.
Purpose of the Study:
- To report a series of 9 cases of LVNC cardiomyopathy diagnosed at University College Hospital, Ibadan.
- To describe the clinical presentation, comorbidities, and management of LVNC patients in this setting.
Main Methods:
- Retrospective review of 9 LVNC cases diagnosed via echocardiography.
- Data collected included patient demographics, clinical presentation, comorbidities, ejection fraction, and non-compacted to compacted segment ratio.
- Management strategies, including medication use, were analyzed.
Main Results:
- Six men and three women presented with LVNC, with a mean age of 52.89 years.
- Heart failure was the most common presentation (6 patients), and hypertension was the most frequent comorbidity (6 patients).
- Mean non-compacted to compacted segment ratio was 2.80, with LV lateral wall and apex being common trabecular localization sites. Beta-blockers were beneficial.
Conclusions:
- LVNC cardiomyopathy is not uncommon in the studied environment.
- A high index of suspicion is necessary for timely diagnosis and management of LVNC.

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...

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

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,...

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...

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

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...
