Question

a. cystic fibrosis.
b. Eisenmenger syndrome.
c. peripartum cardiomyopathy.
d. Marfan syndrome.

Answer 1

D
Marfan syndrome is an autosomal dominant disorder of connective tissue in which serious cardiovascular involvement, usually dissection or rupture of the aorta, may occur. Eisenmenger syndrome is not a single congenital defect but a complication that may be the result of other cardiac lesions that cause left-to-right shunting. Aortic stenosis often is accompanied by other valvular disease, especially disease affecting the mitral valve. The hallmark of aortic stenosis is decreased left ventricular ejection. Peripartum cardiomyopathy (PPCM) is a type of left ventricle dysfunction of unknown origin that occurs in the last month of pregnancy and up to 5 months after delivery in women with no previous history of heart disease. Thus, PPCM is a diagnosis of exclusion. Cystic fibrosis is an autosomal recessive, multisystem disease that affects the exocrine glands and epithelial tissues of the pancreas, sweat glands, and mucous glands of the respiratory, digestive, and reproductive tracts.
