Summary
This case report details a 68-year-old man with recurrent ventricular tachycardia due to large coronary artery aneurysms. Surgical intervention with bypass grafting and aneurysm ligation proved successful, highlighting cardiac CT
Area of Science:
- Cardiology
- Vascular Surgery
- Diagnostic Imaging
Background:
- Coronary artery aneurysms pose risks such as rupture, thromboembolism, and hemodynamic compromise.
- Ventricular tachycardia recurrence prompted evaluation in a 68-year-old male patient.
Observation:
- Coronary angiography identified two large aneurysms in the mid-right coronary artery.
- Multislice computed tomography (CT) revealed significant underestimation of aneurysm size by angiography due to extensive thrombus.
Findings:
- The patient underwent successful cardiac surgery, including right internal mammary artery bypass grafting to the right coronary artery.
- The aneurysms were surgically ligated after thrombus removal, confirmed by postoperative CT.
- Postoperative CT demonstrated bypass graft patency and exclusion of the aneurysms.
Implications:
- Cardiac CT is a valuable tool for comprehensive assessment and postoperative monitoring of coronary artery aneurysms.
- This case underscores the importance of advanced imaging in managing complex coronary artery pathologies.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

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...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
1.1K
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...
