  1. This is a typical presentation of LVH and out of the options A) & E) could be the possible causes.
    But I guess his avoidance of routine care might have left with undiagnosed systemic hypertension. Even, there are no risk factors present that might lead to AR.

    So,my answer would be E)

  2. And ThankYou #FirstAidTeam for publishing such wonderful, interesting questions. Refering them and answers along with the justification has really helped me in successfully clearing my USMLE Step1

    I’m mentioning it here because I am attempting my first post-result question.

  3. E but I need to review more slides on the subject because I also am leaning to A. So I will review and decide.

  4. E. concentric LVH secondary to increased afterload, most likely due to uncontrolled HTN (RF: African-American, male, age, DM)
