On physical exam, she is afebrile, blood pressure 190/102 mm    Hg, pulse 82 /min, respiratory rate 18/min, her jugular venous pulse is elevated. Skin exam shows multiple excoriations over her trunk and extremities. Lung exam reveals bilateral. Lower extremities exam reveals moderate dependent edema. And there are obvious rheumatoid deformities in both hands. The rest of the physical exam is normal.

Case 15

74 years old female presented to the emergency department with worsening shortness of breath associated with abdominal distention.

On physical examination, she is afebrile, blood pressure
was 166/64 mm Hg, the heart rate 86 / minute and irregularly
irregular, the respiratory rate 18 / minute, and, Jugular venous distention
to the angle of the jaw when sitting upright was noted, as were
bibasilar rales. The apex beat of the heart was
enlarged, sustained, displaced leftward, and associated with
a right ventricular heave. There was a grade 3/6 blowing, pansystolic

murmur audible at the left upper sternal border. No rubs or
gallops were heard, and there was no pericardial knock. The
patient's abdomen was distended, with a visible fluid wave,
and her liver was tender, pulsatile, and palpable 12 cm below
the right costal margin. She had peripheral edema (1+).

Echocardiogram showed evidence of tricuspid regurgitation

Which one of the following patterns 74 years old female presented to the emergency department with worsening shortness of breath in the jugular venous pulsation is typical of tricuspid regurgitation?

  1. A giant A wave
  2. A cannon wave.
  3. A prominent C-V wave
  4. A steep y descent.

Case 14

Case 13

A 48 years old male with presented to the emergency department with chest pain and diagnosed with acute myocardial infarction. Within one hour of presentation he develops pulmonary edema, which responds to intravenous Furosemide. The patient had cardiac angioplasty, and his chest pain resolved within 2 hours of onset. An echocardiogram shows inferior akinesa, EF 50 %, and trivial mitral regurgitation. 10 hours later, recurrent chest pain developes, and the manifestation of acute pulmonary edema return.

On physical examination, he is afebrile, blood pressure 108/64, pulse 102/min, and respiratory rate is 28/min. No jugular venous distention, cardiovascular exam reveals left sterna edge pansystolic murmur radiating to the axilla, lungs, there is rales over lower one-third of lung fields.

Q- Why did episodic pulmonary edema develop in this patient?

Case 10

A 66 years old man with history of hypertension presented to the emergency room with a laceration over the left eyebrow and chin after he hit his head to a door he had not seen. He mentioned that he has a cloudy vision in his right eye.

He had right homonoymous quadrantanopia.the rest of the physical exam is normal

He checked his random cholesterol in a health fair 3 months ago and it was elevated.
