Left-ventricular non-compaction with coronary artery disease.
International Journal of Cardiology
|October 27, 2009
Summary
Left-ventricular non-compaction (LVNC) is rare, especially when combined with coronary artery disease (CAD). This case report details a unique instance of LVNC co-occurring with significant CAD in a myocardial infarction patient.
Area of Science:
- Cardiology
- Cardiovascular Imaging
- Pathophysiology
Background:
- Left-ventricular non-compaction (LVNC) is a rare cardiomyopathy characterized by excessive trabeculation.
- Coronary artery disease (CAD) involves the narrowing or blockage of coronary arteries.
- The co-occurrence of LVNC and CAD is exceptionally uncommon in clinical practice.
Observation:
- A 48-year-old male presented with an anterior wall myocardial infarction.
- Two-dimensional echocardiography revealed LVNC, primarily affecting the ventricular septum.
- Significant two-vessel coronary artery disease was also diagnosed in the patient.
Findings:
- This case represents the first documented instance of LVNC associated with coronary artery disease in medical literature.
- The diagnostic findings highlight the potential for concurrent presentation of these distinct cardiovascular conditions.
- Echocardiography proved effective in diagnosing both LVNC and assessing the extent of CAD.
Implications:
- This rare association underscores the importance of comprehensive cardiac evaluation in patients presenting with myocardial infarction, even with atypical underlying conditions.
- Further research may elucidate shared etiological factors or pathophysiological mechanisms between LVNC and CAD.
- Clinicians should consider the possibility of coexisting LVNC in patients diagnosed with CAD, particularly those with unexplained ventricular dysfunction.

01:26Imbalances in Cardiac Output
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send blood...

01:29Cardiomyopathy 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...
01:29Cardiomyopathy 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...
01:30Cardiomyopathy 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,...
01:26Coronary Artery Disease II: Pathophysiology
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
01:25Cardiomyopathy 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...
