Summary
Recurrent syncope can be caused by rare intrathoracic tumors compressing the carotid artery. This case highlights a potential neurocardiogenic link in patients with unexplained syncope and apical neoplasms.
Area of Science:
- Cardiology
- Neurology
- Oncology
Background:
- Syncope is a frequent clinical presentation with complex underlying causes.
- Recurrent syncope necessitates thorough investigation to identify the etiology.
- Intrathoracic tumors are an uncommon but critical differential diagnosis for syncope.
Purpose of the Study:
- To report two cases of recurrent syncope.
- To investigate the association between apical neoplasms and syncope.
- To explore the potential neurocardiogenic mechanism in these cases.
Main Methods:
- Case report of two patients presenting with recurrent syncope.
- Diagnostic workup including exclusion of cardiac arrhythmias, brain lesions, and orthostatic hypotension.
- Imaging studies to evaluate for intrathoracic abnormalities.
Main Results:
- Both patients presented with recurrent syncope without other symptoms.
- Imaging revealed apical neoplasms compressing the left common carotid artery with mediastinal lymphadenopathy.
- Cardiac and major arterial involvement was excluded.
Conclusions:
- Apical neoplasms compressing the carotid artery can be a cause of recurrent syncope.
- A neurocardiogenic mechanism involving vagus nerve involvement is suspected.
- This highlights the importance of considering intrathoracic tumors in unexplained syncope.

01:27Pneumothorax-II
1.7K
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

1.2K
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...

735
Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

01:26Transient Ischemic Attack l: Introduction
18
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
