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.
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.
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.

An STEMI, or ST-segment Elevation Myocardial Infarction, is a condition in which the blood flow to the heart is blocked. This typically occurs due to rupture of a lipid plaque in the wall of an epicardial artery. This causes muscle cell death due to lack of oxygen and other substrates necessary for cell growth/maintenance. The EKG can be used to localize the likely location of the blockage by looking at changes on the EKG. An inferior STEMI is characterized by ST elevations in the inferior limb leads, leads II, III, and aVF, associated with ST depressions (called reciprocal changes) in the lateral limb leads, I and aVL. An inferior STEMI most commonly is associated with a blockage in the right coronary artery (80% of the time). Inferior STEMIs have a slightly better prognosis than anterior MIs. There is typically less heart muscle lost in association with inferior STEMI than when the MI affects the bulkier left side of the heart.
Basal scouring is the process where fast-moving water erodes the riverbed or streambed, creating depressions or holes in the bottom. This can lead to instability of the streambed and potentially create hazards for structures or infrastructure built nearby.
