Summary
Aortic atresia, a rare condition, is challenging to diagnose with echocardiography. Dual source computed tomography is crucial for accurate diagnosis, revealing coronary artery origins.
Area of Science:
- Cardiology
- Medical Imaging
- Pediatric Cardiology
Background:
- Aortic atresia with a ventricular septal defect and a well-developed left ventricle is an exceptionally rare congenital heart defect.
- Accurate diagnosis is critical for appropriate management and surgical planning.
Observation:
- Two cases are presented where echocardiography suggested an alternative diagnosis due to the small caliber of the hypoplastic aortic trunk, leading to it being missed.
- Dual source computed tomography (DSCT) was instrumental in achieving the final diagnosis.
Findings:
- DSCT precisely identified the thin aortic trunk and clearly visualized the coronary artery origins from the hypoplastic aortic root.
- This represents the first reported use of multi-detector computed tomography in diagnosing aortic atresia with a well-developed left ventricle.
Implications:
- Highlights the limitations of echocardiography in diagnosing certain rare congenital heart defects.
- Emphasizes the diagnostic superiority of DSCT in complex cases of aortic atresia.
- Suggests DSCT as a valuable tool for surgical planning in these rare pediatric cardiac anomalies.

987
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...

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

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...

01:16Chambers of the Heart

The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.

The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

01:14The Aorta

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...
