PA P1 (Heart)

Coronary artery "dominance" is defined in terms of which coronary artery supplies the posterior descending artery (PDA).What is the right dominant circulation of the coronary arteries? What is the left dominant circulation of the coronary arteries? Which is more common, right dominant or left dominant?

A patient suffered a MI. During autopsy the side (lateral wall) of the left ventricle was found to be ischemic which artery supplied that region?

*Remember the Obtuse and LEFT Marginal artery are the same thing!* A patient suffered a MI. During autopsy the MOST lateral wall of the left ventricle was found to be ischemic which artery supplied that region?

A patient suffered a MI. During autopsy the lateral right ventricle and a tiny portion of the apex were found to be ischemic which artery supplied that region?

During an autopsy the anterior wall of the left ventricle, most of the apex, and the anterior ⅔ of the septum are ischemic, which artery was most likely occluded?

During an autopsy the posterior left ventricle and posterior ⅓ of the septum are ischemic, which artery was most likely occluded?

A patient has a heart attack. NO changes are seen grossly or microscopically. How long ago was the heart attack?

A patient has a heart attack. Dark mottling is seen grossly and ongoing coagulative necrosis, pyknosis, hypereosinophilia of myocytes, marginal contraction band necrosis, and few neutrophil infiltrates are seen microscopically. How long ago was the heart attack?

A patient has a heart attack. Depressed red-tan margin, with soft yellow-tan center is seen grossly and early granulation tissue, widespread phagocytosis, replacement of neutrophils by macrophages, and phagocytosis of debris are almost complete are seen microscopically. How long ago was the heart attack?

*Remember, Coronary Artery Disease and Ischemic Heart Disease are the same thing!* A patient dies from LEFT-SIDED Heart Failure, what is the most common cause?

An aortic dissection occurs when blood splays apart the laminar planes of the media (blood vessel lumen) to form a blood-filled channel, most commonly found in the ascending aorta. A patient was 70 year old with history of DM, CAD, HTN and other diseases. Patient died and during autopsy, he had an aortic dissection in the abdominal aorta. Which of his past medical history most likely contributed to his aortic dissection?

During an autopsy an aneurysm is identified. What condition most likely was the cause?
