Summary
A 73-year-old man presented with heart failure symptoms. Diagnostic imaging revealed a left ventricular thrombus mimicking hypertrabeculation, which resolved with treatment.
Area of Science:
- Cardiology
- Cardiovascular Imaging
Background:
- Left ventricular thrombus formation can present with diverse imaging characteristics.
- Distinguishing thrombus from native cardiac structures is crucial for accurate diagnosis and management.
Observation:
- A 73-year-old male presented with dyspnea and epigastralgia, elevated brain natriuretic peptide, and ECG abnormalities.
- Echocardiography revealed left ventricular dilatation and hypokinesis with apparent hypertrabeculation.
- Cardiac MRI showed a large apical trabecula with low contrast uptake.
Findings:
- The apparent apical hypertrabeculation was identified as a left ventricular thrombus.
- The thrombus resolved completely following diuretic therapy.
Implications:
- This case highlights the importance of comprehensive cardiovascular imaging and clinical correlation.
- It underscores the potential for cardiac thrombi to mimic native myocardial structures, necessitating careful diagnostic evaluation.

145
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...

173
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
85
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

01:27Mitral Valve Prolapse I: Introduction
154
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

01:22Mitral Stenosis I: Introduction
144
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...

01:15Aortic Regurgitation I: Introduction
174
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
