Summary
This study reports a rare case of paracentral acute middle maculopathy (PAMM), a retinal condition, occurring after surgery for atrial myxoma. The findings suggest a new association between this cardiac tumor resection and PAMM development.
Area of Science:
- Ophthalmology
- Cardiology
- Retinal Vascular Diseases
Background:
- Atrial myxoma is a primary cardiac tumor.
- Surgical resection via median sternotomy is the standard treatment.
- Postoperative complications can affect various organ systems, including the eye.
Purpose of the Study:
- To document a rare case of paracentral acute middle maculopathy (PAMC).
- To describe PAMM occurring in the postprocedural period following median sternotomy for atrial myxoma.
Main Methods:
- Case report involving a 77-year-old female patient.
- Comprehensive ophthalmic evaluation including optical coherence tomography (OCT).
- Systemic history and visual field testing were performed.
Main Results:
- The patient developed blurred vision 10 days post-atrial myxoma resection.
- Ophthalmic examination and OCT confirmed paracentral acute middle maculopathy (PAMM).
Conclusions:
- Paracentral acute middle maculopathy (PAMM) is a rare retinal ischemic condition.
- PAMM can occur after systemic vascular insults.
- This case suggests a novel association between left atrial myxoma resection and PAMM.

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...
01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
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...
01:29Cardiomyopathy 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...
