Valvular heart disease Flashcard Deck - 10 Cards
Flashcard 1: A murmur due to mitral valve prolapse is loudest just before which heart sound? _____
Answer: S2
Flashcard 2: Mitral stenosis is usually due to _____ disease
Answer: chronic rheumatic valve
Flashcard 3: A murmur with a midsystolic click is indicative of what pathology? _____
Answer: Mitral valve prolapse
Flashcard 4: What is the most likely cause of a mid-systolic crescendo-decrescendo murmur heard best at the right upper sternal border that radiates to the carotids?
Answer: Aortic stenosis
Extra: The murmur of aortic stenosis is a mid-systolic crescendo-decrescendo ejection murmur, typically heard loudest at the right second intercostal space (base of the heart) and radiating to the carotid arteries. It is often associated with a weak and delayed carotid pulse (pulsus parvus et tardus).
Flashcard 5: Aortic _____ may arise as a consequence of chronic rheumatic valve disease
Answer: stenosis
Flashcard 6: Late (chronic) lesions of rheumatic heart disease cause mitral _____
Answer: stenosis
Flashcard 7: Aortic _____ is associated with "Pulsus parvus et tardus", meaning pulses are weak with a delayed peak
Answer: stenosis
Flashcard 8: What is Ebstein's anomaly?
Answer: atrialized right ventricle
Flashcard 9: Arteries involved in Medial Medullary Syndrome
Answer: stroke in paramedian branches of ASA and/or vertebral arteries
Extra: Features:
1. Ipsilateral hypoglossal nerve palsy (tongue deviation to side of lesion)
2. Contralateral hemiparesis (pyramidal tract)
3. Contralateral loss of proprioception/vibration (medial lemniscus)
Flashcard 10: Pathophysiology of migraine headache
Answer: irritation of CN 5, meninges, and/or blood vessels
Extra: Involves activation of the trigeminovascular system.
Pathogenesis: Release of substance P, CGRP, and vasoactive peptides.
Clinical features: Pulsating unilateral headache; 4-72 hr duration; +/- nausea, photophobia, phonophobia, aura.
Treatment:
- Abortive: Triptans, NSAIDs
- Prophylactic: Propranolol, Topiramate, Amitriptyline
