Summary
A patient developed a giant coronary artery aneurysm, the largest reported at 63 mm. This occurred 11 years after initial cardiac surgery, highlighting a rare long-term complication.
Area of Science:
- Cardiology
- Vascular Surgery
- Interventional Cardiology
Background:
- A patient presented with severe aortic valve calcification, initially deemed inoperable for aortic valve replacement and aneurysm resection.
- The patient underwent transcatheter aortic valve implantation (TAVI) due to high surgical risk.
Purpose of the Study:
- To report a rare case of a giant coronary artery aneurysm developing 11 years post-TAVI.
- To document the largest giant coronary artery aneurysm identified in medical literature.
Main Methods:
- Coronary angiography was performed 11 years after the initial TAVI procedure.
- Imaging revealed a large aneurysm in the coronary artery with intraluminal thrombus.
Main Results:
- A giant coronary artery aneurysm measuring 63 mm in diameter was identified.
- The aneurysm contained significant intraluminal thrombus.
- This represents the largest giant coronary artery aneurysm documented to date.
Conclusions:
- Giant coronary artery aneurysms can develop as a late complication following cardiac interventions.
- This case underscores the importance of long-term surveillance for rare vascular complications.

01:21Coronary Circulation
5.1K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
89
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...

01:14The Aorta
1.5K
The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...

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...

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
