Which of the following statements regarding aortic stenosis is incorrect?

AIt exclusively affects congenitally bicuspid valves
BIs the most common of all valvular abnormalities
CAcquired aortic stenosis is usually age associated "wear and tear"
DCongestive heart failure and angina pectoris are common clinical presentations

A 7-year-old male presents with a sudden onset of knee, hip and elbow joint pain associated with arthralgia, low to moderate grade fever, a skin rash (described by the mother as "ringworms"), and involuntary purposeless movements. Lab investigations show elevated ESR and C-reactive protein; physical examination reveals pericardial friction rubs, tachycardia, and weak first and second heart sounds, with no murmurs. What is the diagnosis?

ARheumatic fever
BSystemic onset juvenile rheumatoid arthritis
CInfective endocarditis
DSeptic arthritis

Which of the following doesn't link well with rheumatic fever?

AMixed inflammatory infiltrates
BPericardial friction rubs
CSydenham Chorea
DPresence of Aschoff body

A 10-year-old boy presents to the hospital with features of heart failure. On further history taking, it is uncovered that he has previously suffered from repetitive sore throats. He is diagnosed with rheumatic valve disease according to the 2023 World Heart Federation criteria. What pathophysiology underlies this condition?

AAntigen mimicry
BCongenital valvular heart disease
CHypertension
DInfective endocarditis

Concerning endocarditis, choose the correct statement:

ANonbacterial thrombotic endocarditis (NBTE) is a rare condition that refers to a spectrum of noninfectious lesions of the heart valves that is most commonly seen in advanced malignancy
BOver 75% of the cases of infective endocarditis are caused by gram-positive bacteria such as Klebsiella pneumoniae
CApproximately 10% of the cases of infective endocarditis are caused by gram-positive bacteria such as Streptococcus mutans
DCurrently, Streptococcus mutans is more implicated in causing infective endocarditis among drug addicts than enterococci

Circle the odd man out of the following regarding diagnostic criteria for infective endocarditis:

APredisposing heart lesion or intravenous drug use
BPositive blood culture(s) indicating a characteristic organism or persistence of an unusual organism
CEchocardiographic findings, including a valve-related or implant-related mass or abscess
DNew valvular regurgitation
