a = new Array(11); a[0] = "Incorrect" a[1] = "CORRECT. The fishmouth shape to the mitral valve, as seen from the left atrium in the left panel, and the shortening of the chordae tendineae of the mitral valve as seen in the right panel, are characteristic features for chronic rheumatic valvulitis." a[2] = "CORRECT. This is a membranous ventricular septal defect, which results in a left-to-right shunt. Later, as the pulmonary hypertension worsens, the shunt may reverse." a[3] = "CORRECT. The left ventricle is markedly hypertrophic as a result of the pressure load from hypertension. The failing left heart results mainly in left-sided congestive failure with pulmonary edema." a[4] = "CORRECT. This fibrinous pericarditis results from inflammation with exudation of fibrin to form the grossly shaggy appearance." a[5] = "CORRECT. The fibrosis seen here is indicative of a remote myocardial infarction." a[6] = "CORRECT. The aortic valve has large, friable vegetations that have nearly completely destroyed the cusps. This is the typical appearance for an infective endocarditis." a[7] = "CORRECT. There is medial calcification of this small artery. This particular form of arteriosclerosis has no significant consequences and is an incidental finding." a[8] = "CORRECT. The ballooning of the mitral cusp and long, thin chordae tendineae are typical features of a 'floppy' mitral valve that can be seen with Marfan syndrome." a[9] = "CORRECT. The 'apple-green' birefringence of amyloid is seen here, typical for amyloidosis, which can be a cause for infiltrative cardiomyopathy." a[10] = "CORRECT. This is an acute myocardial infarction with contraction band necrosis, and the CK-MB rises within 3 to 4 hours and peaks at about 24 hours." a[11] = "QUESTIONS: 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 "
