JCU MB4 Term 1 Week 2 (MI)

1

Based on the picture, what is the diagnosis?

Healed MI


2

56-year-old with fatigue. Picture of heart shown. What is the diagnosis?

LV aneurysm post-MI


3

A 57-year-old man presents with a 4-hour history of chest pain radiating to his neck, with associated diaphoresis and dyspnoea. His CK-MB and troponin I are mildly elevated, and his ECG shows anterior wall ST elevations. He dies suddenly following a ventricular tachycardia/ventricular fibrillation arrest. The gross appearance of his heart is shown. What is the diagnosis?

Thrombosis of the LAD artery


4

68-year-old man, found dead in his apartment picked up by paramedics. Image shows his myocardial biopsy. What is duration of his MI?

Biopsy of MI at less than 24 hours


5

A 13-year-old girl develops malaise and fever, an irregular circular rash, and forearm subcutaneous nodules 3 weeks after a painful pharyngitis. A new heart murmur and friction run are heard. Her mitral valve anterior leaflet would appear as shown. What is your diagnosis?

ARF - Mitral valve vegetations


6

An infant girl with a late systolic murmur has upper extremity pulses and blood pressures greater than in her lower extremities. She also has a webbed neck and short fourth metacarpals. If an autopsy were performed at this point, we might see a heart and great vessels as shown.

Coarctation of the aorta


7

The image shows the myocardial biopsy of a treated MI. What is the diagnosis?

Biopsy of MI reperfusion haemorrhage


8

The following picture shows a heart cross-section gross specimen at autopsy. What is the diagnosis?

Acute MI with thrombus


9

52-year-old chest pain. Picture of post-mortem heart is shown. What is the most likely cause of death?

MI with wall rupture


10

68-year-old male. Picture shows myocardial biopsy. What is the duration of his MI?

MI biopsy at 1-3 weeks


11

68-year-old recovering following an MI died suddenly while watching television on the 10th day. Myocardial biopsy is shown. What is the likely complication that caused his death?

MI biopsy at 1-3 weeks


12

A 30-year-old intravenous drug user with 2-day history of fever is found to have coarse systolic and diastolic murmurs, splenomegaly, and nail be splinter haemorrhages. His CK-MB is elevated. He experiences sudden cardiac arrest. His aortic valve at autopsy is shown. Why did he die?

Endocardial vegetations


13

The picture shows a myocardial biopsy post-MI. What is the duration of the MI?

MI biopsy 1-3 days


14

The picture shows a myocardial biopsy post-MI (stained blue for collagen). What is the duration of the MI?

MI biopsy (late)


15

72-year-old male, congestive cardiac failure. What is the complication indicated by the pale patches?

MI with aneurysm and fibrosis


16

62-year-old with chronic IHD. What is the complication shown in the image?

LV aneurysm


17

A 45-year-old man with a 6-year history of progressive exertional dyspnoea is found by echocardiography to have an ejection fraction 28% (normal is 50-60%) with systolic dysfunction and mitral regurgitation. His native heart after cardiac transplantation is shown. What is the diagnosis?

Dilated Cardiomyopathy


18

The picture shows a myocardial biopsy post-MI. What is the duration of the MI?

MI biopsy over 3 weeks


19

62-year-old CHD. What is the complication shown in the image?

Healed MI with aneurysm and thrombus


20

A 48-year-old woman with a 5-year history of worsening orthpnoea is found on examination to have atrial fibrillation and a rumbling diastolic murmur with opening snap. The gross appearance of her heart at surgical valve replacement is shown. What are the possible complications?

Mitral Valve Stenosis


21

The picture shows a myocardial biopsy post-MI. What is the duration of the MI?

MI biopsy less than 24 hours
