Revista Española de Cardiología is an international scientific journal devoted to the publication of research articles on cardiovascular medicine. The journal, what is right dominant coronary system sinceis the official publication of the Spanish Society of Cardiology and founder of the REC Publications journal family. Articles are published in both English and Spanish in its electronic edition.

The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact.

SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. Dual left anterior descending LAD artery is a congenital coronary anatomical variant 1 that has several recognized types, 1—3 but a Y-shaped confluent dual LAD has not been previously described. We present the case of a year-old man admitted for elective coronary angiography due to stable exertional what is right dominant coronary system, with a reversible myocardial diffusion defect in the inferolateral left ventricular wall single photon emission tomography with 99m Tc-MIBI.

An angiogram of the right coronary artery RCA showed a nondominant artery with an unusual branch emerging from the proximal segment, passing above the right ventricular outflow tract demonstrated on what is right dominant coronary system tomography angiography and reaching the anterior interventricular sulcus, where it joined the LAD proper to form the vessel that normally reaches the apex Figure 1A-D.

Video 1 of the supplementary material shows retrograde entry of the contrast towards the left coronary artery LCAalthough the antegrade blood flow does not allow visualization of the circumflex artery. C and D: multiplanar reconstruction of tomographic images. E: left coronary angiography anteroposterior cranial view ; dominant Cx and severe lesion of LCA arrow. F: stent implantation. G: result of the coronary intervention and confluence of the 2 branches that continue as a single vessel distal LAD, arrowhead toward the apex.

Left coronary angiography showed a severe eccentric stenosis in the LCA, which was treated with a 3. Spider view video 2 of the supplementary material shows the LCA lesion, left-dominance, and the competitive flow in the LAD. This anatomical variant was beneficial because it worked as an arterial graft for the LAD; therefore, the ischemic consequences only affected the myocardial territory supplied by the circumflex artery.

Without this variant, the patient would have had a worse clinical condition due to the severe LCA disease plus left dominance, which behaves like severe triple-vessel disease; what is right dominant coronary system, this natural hemorheological adjustment explains the reversible perfusion defect found only in the inferolateral wall and minimized the risk during the percutaneous coronary intervention.

The LAD is the coronary artery with the most consistent origin, course, and distribution in the human heart. InSpindola-Franco et al. Other variants and subtypes have been proposed, 4 but none have described an anatomical distribution in which the branch what is the meaning of correlation coefficient in arabic comes off the RCA converges with the LAD to form this single vessel that would usually supply the apex.

For this reason, we describe it as a Y-shaped confluent dual LAD. The importance of familiarity with all the dual LAD variants has significant implications in clinical practice and can be a powerful tool for interventional cardiologists and cardiovascular surgeons; therefore, it raises the question: is this anatomical variant really a congenital coronary anomaly or is it the result of a collateral circulation, stimulated by the severe LCA stenosis?

What is right dominant coronary system the answer is the latter, it could be part of Vieussens anastomotic ring, 5 which, in certain clinical small business class 11 ncert solutions anatomical circumstances, such as ischemia, develops to increase the volume of blood flow to help the myocardial territory corresponding to the LAD; however, the branch coming off the RCA does not have the tortuous character or microvascular anastomoses capillary network of a collateral circulation, its caliber is similar to or larger than that of the other epicardial arteries, and its confluence with the LAD proper, at the level of the anterior interventricular sulcus, occurs much more distal than the emergence what is coronavirus essay in english the second diagonal branch.

To date, in all the known types of dual LAD, the long and short branches are divergent or have independent origins ostia1—4 but never before has an anatomical variant with convergent or confluent branches been described, such as the case presented here Figure 2. Thus, it could be proposed as a type VI in the modified classification by Spindola-Franco et al. Diagrammatic representation of the anatomical variant described.

In view of the low total number of described cases, there is no evidence pointing to the potentially favorable anatomical variant that could justify the wait-and-see attitude and surgical treatment delay.
