Reghard du Toit
The oblique orientation of the heart causes the ventricles to lie anterior and inferior to the atria.
Pericardial reflections (basically the boundaries of the closed sac) :
Some fat is present between the epicardium and myocardium and this normally increases with age.
Axial CT scan shows a large cardiophrenic fat pad. Normal variant.
The aortic valve has three semilunar cusps, anterior and left and right posterior.
Three chamber MPR shows left ventricular papillary muscles and chordaetendineae
Coronal MPR shows LV papillary muscles
Right ant oblique
The brachiocephalic veins are formed by the union of the internal jugular and subclavian veins behind the medial end of either clavicle.
The left main pulmonary artery passes to the left, initially in front of the left main bronchus but then curves superior to the bronchus.
