- However, an aberrant right subclavian artery was identified coursing posterior to the esophagus. In the US, the cost for subclavian artery intervention is about $10,000. The investigators followed 415 Hodgkin's survivors who had received radiation to fields including the heart, carotid artery, or subclavian artery.

- Coronary angiography revealed a left anterior descending artery (LAD) with a severe stenosis in the proximal segment extending the ostium of LAD (Figure 1a and b).After discussion with the patient, a decision was made to proceed with percutaneous coronary intervention (PCI) and stenting.o determine whether the ostial plaque of LAD involved the distal left main coronary artery (LM) and the left-circumflex coronary (LCX) ostium, we decided to perform pre-intervention intravascular ultrasound (IVUS) using standard technique.

- The left subclavian artery arises from the arch of the aorta, ascends through the superior mediastinum and enters the root of the neck posterior to the left SC joint. The subclavian veins both end at their respective SC joints by uniting with the internal jugular vein to form the brachiocephalic veins.

- Aberrant right subclavian artery (ARSA) is the most common anomaly of the aortic arch. Its incidence varies from 0.5 to 2.5 % [1]. The artery originates on the left side as a last branch of the aortic arch beyond the left subclavian artery. It follows an oblique course, crossing upward and to the right behind the oesophagus.

- Our case describes a rare form of left dominant coronary circulation in which LAD wraps around the apex forming posterior descending coronary artery. This has resulted in isolated inferior wall myocardial infarction due to distal LAD occlusion.

Subclavian artery The first part of the left subclavian artery arises from the arch of the aorta, behind the left common carotid, and at the level of the fourth thoracic vertebra; it ascends in the superior mediastinal cavity to the root of the neck and then arches lateralward to the medial border of the Scalenus anterior.

Right coronary artery Right coronary artery. In the coronary circulation, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the heart. It travels down the right coronary sulcus, towards the crux of the heart. It branches into the posterior descending artery and the right marginal artery. Although rare, several anomalous courses of the right coronary artery have been described including origin from the left aortic sinus. At the origin of the RCA is the conus ...

- Notably, the right coronary artery branches supply the sinus and atrioventricular nodes; hence, blockage in these vessels can lead to conduction abnormalities. Coronary artery disease is generally defined as the gradual narrowing of the lumen of the coronary arteries due to atherosclerosis.

Hemodynamics Other major arteries have similar levels of blood pressure recordings indicating very low disparities among major arteries. In the innominate artery, the average reading is 110/70 mmHg, the right subclavian artery averages 120/80 and the abdominal aorta is 110/70 mmHg.

Acquired cardiovascular disease: Aortic valveAtypical aortic arch branching variants: A novel marker for thoracic aortic disease An aberrant right subclavian artery was defined as a fourth vessel arising distal to the LSA and crossing to the posterior of the mediastinum toward the upper right extremity. These 3 most common anatomic variations are illustrated in Figure 1.

Subclavian steal syndrome In the setting of increased resistance in the proximal subclavian artery, blood may flow backward away from the heart along the ITA causing myocardial ischemia. Vertebral-subclavian and coronary-subclavian steal can occur concurrently in patients with an ITA CABG.

Heart Anatomy The aorta is the major blood vessel that arises from the left ventricle and is separated from it by the aortic valve. The left main coronary artery arises from above the left portion of the aortic valve and then usually divides into two branches, known as the left anterior descending (LAD) and the circumflex (Circ) coronary arteries. In some patients, a third branch arises in between the LAD and the Circ. This is known as the ramus (pronounced ray-muss), intermediate , or optional diagonal coronary artery. The LAD travels in the groove (known as the inter-ventricular groove) that runs in the anterior or front portion the heart.

- Answer: Left Axis Deviation (LAD) refers to the pattern of electrical activation that occurs in the heart. LAD is an EKG-specific finding and not necessarily indicative of any specific cardiovascular condition. was recently found to have Left Axis Deviation (LAD) on my EKG. General responses to selected questions from Joel Braunstein, MD, of Johns Hopkins University and Joseph Toscano, MD.

Aberrant subclavian artery Aberrant subclavian artery, or aberrant subclavian artery syndrome, is a rare anatomical variant of the origin of the right or left subclavian artery. This abnormality is the most common congenital vascular anomaly of the aortic arch, occurring in approximately 1% of individuals.
