Congenital contractural arachnodactyly (CCA), also known as Beals-Hecht syndrome, is a rare autosomal dominant congenital connective tissue disorder. As with Marfan syndrome, people with CCA typically have an arm span that is greater than their height and very long fingers and toes. However, Beals and Hecht discovered in 1972 that, unlike Marfans, CCA is caused by mutations to the fibrillin-2 (FBN2) gene rather than the fibrillin-1 (FBN1) gene. Signs and symptoms
CCA is characterized by contractures of varying degrees, mainly involving the large joints, which are present in all affected children at birth. The contractures may be mild and tend to improve over time, but permanently bent fingers and toes (camptodactyly) are almost always present. In addition to long fingers and toes and a tall, slender body, people with CCA often have ears that appear to be crumpled, joint stiffness and underdeveloped muscles (muscular hypoplasia), and they may have curved spines (congenital kyphoscoliosis). If kyphoscoliosis is present, it often becomes progressively worse and may require surgery. In some cases, the blood vessel that distributes blood from the heart to the rest of the body (aorta) may be abnormally enlarged (aortic root dilatation). Causes
Congenital contractural arachnodactyly may be the result of new mutations in the FBN2 gene or it may be inherited from a parent in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder.
Coronary artery aneurysm is an abnormal dilatation of part of the coronary artery. This rare disorder occurs in about 0.3–4.9% of patients who undergo coronary angiography. Signs and symptoms
Causes
Acquired causes include atherosclerosis in adults, Kawasaki disease in children and coronary catheterization. With the invention of drug eluting stents, there has been more cases implying stents lead to coronary aneurysms. The pathophysiology, although not completely understood, might be comparable to that of aneurysms of larger vessels. This includes disruption of the arterial media, weakening of the arterial wall, increased wall strain and slow dilatation of the coronary artery portion.It can also be congenital. The following risk factors are thought to be associated with coronary artery aneurysms:

Individuals genetic make-up, especially in patients with congenital coronary artery aneurysms
Coronary artery disease (atherosclerosis)
Vasculitic and connective tissue diseases (Kawasaki and Marfan)
Intracoronary manipulation leading to local wall stress (stent placement, angioplasty, brachytherapy)
Post-infectious as a consequence of direct wall infiltration or immune complex deposition

Diagnosis
It is often found coincidentally on coronary angiography. Other modalities that can be used to diagnose a coronary artery aneurysm include echocardiography, magnetic resonance imaging and computerized tomography. Although coronary angiography remains to be the gold standard, the invasive procedure comes with its associated risks, is more expensive than other modalities and the size of the aneurysm might be miscalculated if there is a thrombus in place. Treatment
Treatment for coronary artery aneurysm include medical management, surgery and percutaneous intervention. Underlying coronary artery risk factors should be addressed in patients with atherosclerosis and proper guideline-mediated medications should be started.
