Seth A, Mathur A, Mathur N, Pahadiya HR. Marfan syndrome. Curr Med Issues 2022;20:265-6
A 34-year-old male presented with exertional breathlessness (New York Heart Association grade III) and palpitation due to chronic aortic insufficiency and bicuspid aortic valve in the past 6 months. He also had progressive diminution of vision. He denied a history of trauma. There was no history of similar illness in his family. On examination, he had elongated fingers. His arm span was 190 cm and his height was 178 cm. His thumb protrudes from the clenched fist “Thumb sign” or “Steinberg sign” [Figure 1]a. He could easily grip his wrist with overlapping of thumb and little finger of opposite hand “Wrist sign” or “Walker–Murdoch sign” [Figure 1]b. His uncorrected visual acuity was 6/18 in both eyes. Slit-lamp examination revealed temporosuperior subluxation of lenses with zonular deficiency in both eyes [Figure 1]c. Skin striae are noticed on the abdomen of the patients [Figure 1]d. The patient also had other features of Marfan syndrome, including a high-arched palate, pectus excavatum, crowding of teeth, and flat feet. Genetic testing was not done due to affordability issues.

Marfan syndrome is an uncommon, connective tissue disorder, inherited as autosomal dominant pattern, and characterized by loss of connective tissue. Few patients can have sporadic mutations. This results skeleton abnormalities which include long and slender fingers (arachnodactyly) and extremities with hypermobile joints, dislocation of lenses, and cardiovascular abnormalities., Aortic root dilatation with or without dissection, aortic insufficiency, bicuspid aortic valve, mitral valve prolapse, and mitral regurgitation are common cardiac problems. The subluxation of lenses may subclinical and are usually bilateral. Cataract, retinal detachment, or glaucoma can develop. Skin striae in Marfan syndrome are common at sites subjected to stress such as the shoulder, hip, buttock, abdomen, and back. Other common features of Marfan syndrome, includes ductal ectasia, high-arched palate, pectus excavatum, pectus carinatum, scoliosis, crowding of teeth, pes planus, and pneumothorax. Slit-lamp examination and echocardiography should be done in all suspected cases of Marfan syndrome. The diagnosis is done with the help of international Ghent standard criteria. “Seven signs” of Marfan may be used for screening purpose, which assign 4 points to ectopia lentis, 2 to family history of Marfan syndrome, and 1 point to previous thoracic surgery, to wrist and thumb sign, to previous pneumothorax, to skin striae, and to pectus excavatum. The pretest probability of Marfan syndrome is classified as follows; low (≤1 point), moderate (1–3.5 points), and high (≥3.5 points)., Multidisciplinary surgical approach of cardiac valves, bracing or surgeries of scoliosis, and vitreoretinal and cataract surgeries have been used successfully in many patients. Aortic root dilation (>4.5 cm) may be delayed with the use of beta-blocker, or angiotensin II receptor blocker. Social and psychological support and regular follow-up are required.,,,
