An inferior wall mycardial infarction is a heart attack involving the inferior portion of the left ventricle, and in many cases the right ventricle. This is caused by occlusion of the right coronary artery. This can also indicate ischemia (poor oxygenation) of the AV node and bundle of HIS, as these structures are also supplied by the right coronary. An inferior wall MI can be seen in the inferior leads II, III, and AVF.

An inferior, not interior, infarction is a subclassification of a heart attack. An inferior myocardial infarction occurs when there is a blockage in the inferior wall of a coronary artery.
Ischemia is the condition in which an artery has become abnormally widened because of a weakness in the arterial wall.

the inferior border of the heart is formed by both the right and leftventricles, but the inferior (diaphragmatic) surface of the heart isprimarilymade from the Leftventricle. Kaplen Anatomy 2012, section 3 gross anatomy, page 212.
