Match each clinical presentation with its most characteristic echocardiographic finding.
- A 22-year-old collegiate athlete with a harsh systolic murmur that increases in intensity during the Valsalva maneuver.Asymmetric septal hypertrophy and systolic anterior motion of the mitral valve leaflet.
- A 74-year-old man with progressive heart failure, macroglossia, and bilateral carpal tunnel syndrome.Increased ventricular wall thickness with a granular, sparkling myocardial appearance and biatrial enlargement.
- A 38-year-old woman with new-onset orthopnea and pedal edema two weeks after a severe Coxsackievirus B infection.Markedly dilated left ventricular cavity with global hypokinesis and a reduced ejection fraction.
- A 65-year-old woman with sudden-onset pulmonary edema and a loud apical holosystolic murmur five days after an inferior ST-elevation myocardial infarction.Ruptured posteromedial papillary muscle resulting in a flail mitral leaflet and severe eccentric regurgitation.
Cevap
The presentations correspond respectively to hypertrophic cardiomyopathy (asymmetric septal hypertrophy), cardiac amyloidosis (sparkling myocardium), viral myocarditis-induced dilated cardiomyopathy (dilated cavity with hypokinesis), and post-myocardial infarction papillary muscle rupture (flail mitral leaflet).
Each clinical vignette provides classic pathognomonic historical and physical examination clues for a specific cardiovascular pathology. These clinical diagnoses map directly to their corresponding structural and hemodynamic abnormalities visualized on echocardiography.
