2006-02-21 To what extent does the statement that the right coronary artery supplies the right heart, and the left coronary artery supplies the left heart, require qualification? What are some of the sites of predilection of coronary occlusions? Myocardial infarction (MI) refers to tissue death of the heart muscle caused by ischaemia, that is lack of oxygen delivery to myocardial tissue.It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart. Unlike the other type of acute coronary syndrome, unstable angina, a myocardial infarction occurs when there is cell Treating patients with chronic total coronary occlusions (CTO) is one of the toughest challenges in the management of coronary artery disease (CAD). Nowadays, the indications for prescribing percutaneous coronary interventions (PCI) in patients with CTOs and the possible impact of revascularization on final prognosis are controversial. recurrent coronary artery occlusions and the tors and long-term prognosis of myocardial in-farction with an absolutely normal coronary angiogram. Eur Heart J 2001; 22: 1459-1465.

Sometimes a plaque may rupture and release vasoactive or thrombogenic substances that lead to clot formation. If there is adequate collateral circulation to the heart muscle at coronary occlusions is one of the most difficult for the technical performance of interventional procedures. Successful recanalization CTO associated with better survival compared to patients where the procedure of recanalization of occlusion was not successful. Percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs) is increasingly being performed in patients with advanced coronary artery disease, but there is limited information on the techniques utilized and the procedural outcomes.

As a result, he underwent a second coronary angiography, which demonstrated a patent stent without significant thrombosis. Normal coronary angiograms can be found at 8-12% in patient with acute myocardial infarction [14].

Ocular ischemic syndrome occurs at a mean age of 65 years, is rare before 50, has no racial predilection. Men are affected twice as often as women likely due to the higher incidence of atherosclerotic disease in males. Bilateral involvement may occur in up to 22% of cases.

Coronary arterial dominance is defined by which coronary artery gives rise to the vessels that supply the inferior aspect of the heart. In this right-dominant heart, the RCA gives rise to the posterior descending artery and posterolateral ventricular branch (PLVB) and supplies the posterior one-third of the interventricular septum and inferior

• Success rates of recanalizing CTOs: 47%–72%. – Requires greater skill, longer case time – Technology development has not increased success rates. • Serious complication rates similar to non-CTO • All complications rate: 6.8% to 20% • More resource intensive (greater radiation and fluoroscopy exposure, increased Treating patients with chronic total coronary occlusions (CTO) is one of the toughest challenges in the management of coronary artery disease (CAD). Nowadays, the indications for prescribing percutaneous coronary interventions (PCI) in patients with CTOs and the possible impact of revascularization on final prognosis are controversial. Recently, a coronary artery occlusive dis-ease study by Li et al. [9] introduced the use of the reverse attenuation gradient sign to differ-entiate chronic total occlusions and subtotal occlusions.

EuroIntervention. 2019 Oct 4;15 (9):e788-e795. doi: 10.4244/EIJ-D-18-00113. 2019-10-04 · Prediction of side branch occlusions in percutaneous coronary interventions by coronary computed tomography: the CT bifurcation score as a novel tool for predicting intraprocedural side branch occlusion. A CTO was defined as a complete occlusion of a major epicardial coronary artery existing for at least six weeks (mean, 7 +/- 5 months).

If these vessels are affected bysevere arteritis diminished blood supply to the walls ofthe proximal coronary arteries could result.10 Thismaybewhyinfants are at greater risk These occlusions tended to cluster within the proximal third of segments between 10 and 40 mm (48%, 43 of 90) and in the each coronary artery. The current study agrees with Wang et segments beyond 70 mm from the RCA ostium (32%, 29 of al. regarding the proximal distribution of LAD (83%) and 90).
