Sequence of Events Blood Flow Through the Heart
Test your knowledge of the flow of blood through the heart by placing the following cardiac events in the proper
order. The first step has been provided to get you started. Arrange the subsequent events by inserting the numbers
2 through 18 in the spaces provided.
1. Deoxygenated blood flows through the superior and inferior vena cava and into the right atrium.
A. Blood fills the left atrium.
B. The right atrium contracts.
- C. The pulmonary valve closes.
D. Blood leaves the lungs via the pulmonary veins.
E. The left atrium contracts.
F. The pulmonary valve opens.
G. Blood flows into the aorta for distribution throughout the body.
H. The mitral valve closes.
1. The left ventricle contracts.
J. The aortic valve opens.
K. The right ventricle contracts.
L. The tricuspid valve opens.
M. Blood is pumped into the right and left pulmonary arteries and into the lungs.
N. Blood fills the left ventricle.
O. The mitral valve opens.

A 50-year-old male patient arrives in the emergency department complaining of severe chest pain. He is taken to the cardiac cath lab for a coronary angiogram and left ventriculogram. The cardiologist discovers a lesion in the left main coronary artery branch and orders an immediate CABG.
1. Why does the location of this lesion make it more dangerous than lesions in other locations?
2. What does the acronym CABG stand for?
3. Assuming that the CABG is successful, what is the patient's postoperative prognosis?
4. Could the cardiologist perform an angioplasty to repair the lesion?
1. Mr. Garcia had a myocardial infarction. Explain what
happened to his heart muscle and vascular system.
What is a STEMII?
2. Mr. Garcia's chest pain resolved after two sublingual
NTF at 3-minute intervals and 2 mg of IV morphine.
In the cardiac catheterization lab he was "found to have
a totally occluded distal right coronary artery and a 70%
occlusion in the left circumflex coronary artery. The left
anterior descending artery was patent. Angioplasty of the
distal right coronary artery resulted in a patent infarct-
related artery with near normal flow. A stent was left in
place to stabilize the patient and limit infarct size. Left
ventricular ejection fraction was normal at 42%, and a
posterobasilar scar was present with hypokinesis."
a. Explain angioplasty and stent placement. Define
occluded occlusion.
b. What is the purpose of this medical procedure?
