Explanation:

1. The right atrioventricular valve is the tricuspid valve. The mitral and bicuspid valves are the same (left atrioventricular), and the semilunar valves are at the exits of the ventricles (pulmonary and aortic).
2. The pericardium is the double - walled membrane around the heart. The peritoneum is around abdominal organs, perimyocardium is not a standard term, and pericardosis is a disease of the pericardium.
3. A septum is a partition. A valve controls flow, lumen is the inside space of a vessel, and plaque is a deposit.
4. An infarct is necrosis due to interrupted blood supply. Ischemia is lack of blood flow (before necrosis), resuscitation is reviving, and pulse is the beat.
5. Transfusion is introducing blood. Embolism is a blockage, thrombus is a clot, and stent is a device.
6. A shunt is a bypass. Preload is a cardiac term related to filling, stent is a device, tourniquet stops bleeding.
7. "Cor" means heart.
8. Cardiomyopathy is heart muscle disease. Cardiopathy is general heart disease, cor pulmonale is right heart enlargement from lung issues, cardiovalvopathy is valve disease.
9. Cardiomegaly is heart enlargement. Cardiac swelling is not the term, augmentation is increasing (not specific), dilation is stretching (but cardiomegaly is the standard term).
10. Perfusion is blood flow through tissue. Ischemia is lack of flow, infarct is dead tissue, auscultation is listening.
11. Pulmonary arteries carry blood from heart to lungs. Pulmonary veins carry back, vena cava brings blood to heart, aorta carries blood from heart to body.
12. Systole is contraction. Diastole is relaxation, septum is a wall, tachycardia is fast heart rate.
13. Iatrogenic is caused by treatment. Idiopathic is unknown cause, congenital is from birth, hereditary is genetic.
