Usually right-side heart failure occurs in response to left-side failure. The backup of blood in the lungs caused by left-side heart failure makes the right ventricle work harder. This overload of work can cause the right side of the heart to fail. Right-side heart failure can also accompany other conditions, such as lung disease.
Grus (/ËÉ¡rÊs/ , or colloquially /ËÉ¡ruËs/) is a constellation in the southern sky. Its name is Latin for the crane, a type of bird. It is one of twelve constellations conceived by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman.
The Ramus is a branch off the Left Main and lies between the LAD and LCX and not everyone has a Ramus. Instead of the Left Main splitting into 2 vessels (LD And LC) it splits into 3 vessles (LD, LC and Ramus). But the Ramus is considered a branch (and not a vessel)of the either the LD or the LC so the branch rules apply. You are placing a stent on 1 vessel and another stent on a branch of a 2nd vessel with both coming off of the Left Main. Medicare has been pretty clear that they will only consider interventions on the 3 vessles identified by CPT, the LD, LC and RC.
