Not an IDE4 as such but a short basic lecture on the gross anatomy, function of the Heart
This is my own schematic drawing of the heart.

4 chambers
4 valves::
Mitral 2 leaves, Left Atrium to Left Ventricle
Tricuspid 3 leaves, Right atrium to Right Ventricle
Aortic 3 leaves, Left Ventricle to Aorta
Pulmonary 3 leaves, right Ventricle to Pulmonary Artery

4 pulmonary veins transport oxygenated blood from the lungs to the left atrium. Pulmonary artery takes de-oxygenated blood from the right ventricle to the lungs.

Note Myocardium
Note Apex
Note function of the root of the aorta, and attachment of the three coronary arteries.
LDA, Circumflex and RCA

Some pathology
Ischemia, may lead to AMI or perhaps merely angina
Hypertrophy (often due to chronic high blood pressure)
Infective endocarditis, may cause stroke requires quite aggressive and sustained treatment, consider friable material coming of the valve causing a stroke to the brain. Stenosis (narrowing) of a valve, mitral stenosis may be more common purportedly because it is a 2 leave valve
