A rare myxoma-like right atrial thrombus causing syncope: A case report

|October 4, 2018
Summary
A rare case of syncope caused by a right atrial thrombus mimicking myxoma was successfully treated. Echocardiography is crucial for identifying thrombus risk in syncope patients.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Diagnostic Imaging
Background:
- Syncope presents a diagnostic challenge due to its diverse etiologies.
- Right atrial myxoma-like thrombus causing syncope is an uncommon presentation, especially in patients without underlying structural heart disease.
Observation:
- A 61-year-old male presented with sudden syncope.
- Echocardiography revealed a right atrial mass, initially suspected as myxoma, later confirmed as thrombus after surgical resection.
- Computed tomographic pulmonary angiography identified pulmonary embolism.
Findings:
- Surgical resection of the myxoma-like right atrial thrombus and bilateral pulmonary artery emboli was performed.
- Histological examination confirmed the mass as a thrombus, not myxoma.
- The patient received 6 months of warfarin therapy post-operatively.
Implications:
- A history of femoral neck fracture may predispose individuals to thrombus formation.
- Echocardiography should be considered in evaluating syncope, particularly in patients with risk factors for thrombus formation.
- This case highlights the importance of accurate diagnosis and timely intervention for atrial thrombi presenting as syncope.

01:24Data Reporting and Recording
5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

02:11Reporter Genes
13.3K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...
