His medical history is notable for a previous myocardial infarction. He states that he has not seen a doctor in "many years". He has no complaints. When you auscultate over the cardiac apex with the bell of your stethoscope, you notice an additional sound immediately preceding S1. This extra heart sound is most likely indicative of which of the following processes? QID: 100657 Type & Select Correct Answer 1 Increased left ventricular compliance 6% (14/223) 2 Decreased left ventricular compliance 70% (157/223) 3 Increased left ventricular filling volume 11% (25/223) 4 Decreased left ventricular filling volume 9% (19/223) 5 Increased pulmonary compliance 0% (1/223) M 1 Question Complexity D Question Importance Select Answer to see Preferred Response SUBMIT RESPONSE 2 Review Tested Concept Review Full Topic (M1.CV.13.130) A 79-year-old man presents to the emergency room after a syncopal event. The patient has a history of hyperlipidemia for which he is taking atorvastatin. On physical examination, his vital signs are stable, but on cardiac auscultation, you detect a crescendo-decrescendo systolic murmur loudest on the right upper sternal border radiating to the neck. On physical exam, one would also expect: QID: 100646 Type & Select Correct Answer 1 That the murmur would best be heard in the lateral left decubitus position 6% (9/153) 2 The character of the murmur would be machine-like 3% (5/153) 3 The murmur would also have a mid-systolic click loudest before S2 11% (17/153) 4 The murmur would also have an opening snap 9% (14/153) 5 Palpation of the carotid pulse would be weak and late relative to the patient’s heart sounds 69% (106/153) M 2 Question Complexity E Question Importance Select Answer to see Preferred Response SUBMIT RESPONSE 5 Review Tested Concept Review Full Topic (M1.CV.13.26) A 65-year-old male presents to his cardiologist to discuss increasing episodes of dyspnea after climbing stairs. He also now needs three pillows at night to sleep. Physical examination reveals an early diastolic murmur best appreciated at the left sternal border with bounding peripheral pulses. The cardiologist is very concerned and immediately refers the patient for a surgical workup. What is the most likely diagnosis?

She reports that her symptoms have progressed over the past several months and are now impacting her quality of life because she cannot complete her usual exercise routine. She recalls "normal" childhood illnesses, including sore throats and fevers, but never required hospitalization. Vital signs are temperature 37 degrees Celsius, blood pressure 110/70 mm Hg, heart rate 109/min, respiratory rate 22/min, and oxygen saturation 98% on room air. Physical exam reveals a holosystolic, high-pitched, blowing murmur at the cardiac apex.

She has no complaints with the exception of occasional "shortness of breath." Her physical examination is unremarkable with the exception of a "snap"-like sound after S2, followed by a rumbling murmur. You notice that this murmur is heard best at the cardiac apex. A history of which of the following are you most likely to elicit upon further questioning of this patient? QID: 100633 Type & Select Correct Answer 1 Family history of aortic valve replacement at a young age 6% (7/119) 2 Hyperflexibility, vision problems, and pneumothorax 7% (8/119) 3 Systolic click auscultated on physical exam 10 years prior 5% (6/119) 4 Repeated episodes of streptococcal pharyngitis as a child 78% (93/119) 5 Cutaneous flushing, diarrhea, and bronchospasm 0% (0/119) M 2 Question Complexity B Question Importance Select Answer to see Preferred Response SUBMIT RESPONSE 4 Review Tested Concept Review Full Topic (M1.CV.13.142) A 48-year-old homeless man presents to clinic complaining of fatigue and fevers that "began recently."
