Subsequently, these patients are more likely to undergo PCI more than 24 hours from onset of symptoms compared to patients with more readily recognizable left anterior descending (LAD) and right coronary artery (RCA) occlusions. 5 LCX lesions are associated with increased risk of heart failure and mortality at 90 days and 1 year compared to RCA and LAD lesions. 7 In addition, there have been
However up to 20% of hearts may be left dominant, where the PDA is supplied by the LAD or LCx or codominant, where a single or duplicated PDA is supplied by branches of both the RCA and LAD/LCx. When the RCA gives off PDA, the anatomy is referred to as right-dominant system (if the Lcx gives off PDA, it is referred to as left-dominant system). In patients with right-dominance the RCA supplies the atrioventricular (AV) node. In 60% of individuals the right coronary artery gives off branches to the sinoatrial (SA) node.
The left coronary artery typically runs for 10 to 25 mm, and then bifurcates into the anterior interventricular artery (also called the left anterior descending (LAD) and the Widow maker) and the left circumflex artery (LCx). Sometimes, an additional artery arises at the bifurcation of the left main artery, forming a trifurcation; this extra artery is called the ramus or 2017-12-29 Disease of all three coronary arteries (LAD, LCX and RCA). Diffuse disease not amenable to treatment with a PCI. The 2005 ACC/AHA guidelines further state that CABG is the preferred treatment with other high-risk patients such as those with severe ventricular … Superdominant RCA (no LCx) Arising from the NCS . RCA Tunnel . Intramyocardial courses (“myocardial bridging”) SINGLE CORONARY ARTERY . Arising from the RSV: R1: Follows the normal course of an RCA ( Fig. 9-36 ) R2: LCA crosses at base of heart ( Figs.
2015-12-23 · Inferior STEMI is as common as Anterior STEMI .Unlike the anterior STMI which auto localises to LAD , inferior STEMI has to be fixed either RCA or LCX. Following ECG features help localize Inferior STEMI . ST elevation in lead 3 > lead 2 suggest RCA (Not always true ) ST depression in lead V1,V2,V3 strongly suggest LCX.
