right-to-left shunt

a dusky blueness of the skin (cyanosis) results because the pulmonary circulation is bypassed and poorly oxygenated blood enters the systemic circulation.

acute coronary syndrome

applied to any of the three catastrophic manifestations of IHD—unstable angina, acute MI, and SCD.

Subendocardial infarctions

are MIs limited to the inner third of the myocardium; these infarcts typically do not exhibit ST segment elevations or Q waves on the ECG tracing.

preductal coarctation

characterized by circumferential narrowing of the aortic segment between the left subclavian artery and the ductus arteriosus

stable angina

occurring predictably at certain levels of exertion

unstable angina

occurring with progressively less exertion or even at rest

Transmural infarctions

the full thickness of the ventricle and are caused by epicardial vessel occlusion through a combination of chronic atherosclerosis and acute thrombosis

Eisenmenger

unoxygenated blood into the systemic circulation

Prinzmetal angina

vessel spasm
