Summary
This study identifies aortic arch angulation, tortuosity, and type III arch as key geometric risk factors for atherosclerotic transforming aortic بیماری (aTBAD). These findings enhance understanding of aTBAD development and risk prediction.
Area of Science:
- Cardiovascular Research
- Medical Imaging Analysis
- Geometric Risk Factor Identification
Background:
- Atherosclerotic transforming aortic بیماری (aTBAD) is a significant clinical concern.
- Understanding the geometric factors contributing to aTBAD is crucial for risk stratification.
- Previous studies have explored various risk factors, but specific geometric predictors require further elucidation.
Purpose of the Study:
- To identify specific geometric risk factors associated with atherosclerotic transforming aortic بیماری (aTBAD).
- To elucidate changes in aortic morphological parameters in patients with aTBAD.
- To develop predictive models for aTBAD occurrence based on geometric factors.
Main Methods:
- Retrospective analysis of aortic morphological data from 167 aTBAD patients and 196 controls using 3mensio Vascular software.
- Evaluation of aortic diameter, length, angulation, tortuosity, and aortic arch type.
- Development of multivariable logistic regression models and receiver operating characteristic (ROC) curve analysis to identify predictors and assess model performance.
Main Results:
- Patients with aTBAD exhibited significantly greater aortic diameters and lengths in the ascending aorta and aortic arch.
- Increased angulation and tortuosity of the aorta were observed in the aTBAD group.
- A significantly higher prevalence of type III aortic arch was found in the aTBAD group.
- Aortic arch angulation, tortuosity, and type III arch were identified as independent geometric predictors of aTBAD.
Conclusions:
- Enlargement of the ascending aorta and aortic arch are associated with aTBAD.
- Incremental aortic arch angulation, tortuosity, and type III arch configuration are valuable geometric risk factors.
- These geometric factors can enhance the prediction of aTBAD incidence.

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...

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...

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...

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

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...
