title: [Circumflex angioplasty in a patient with type IV dual left anterior descending coronary artery. Proposal for updating the classification of Spindola-Franco].
abstract: The normal anatomy of coronary arteries includes a kind of variants with regard to its origin, distribution and route, which makes that 2 patients do not have coronary arteries exactly alike. Left anterior descending artery could have anatomical variations that do not affect the normal supply of blood to the corresponding myocardial territory. In our 25 years of experience, and more than 11,000 coronary angiographies, we have found only one patient with a type IV dual left anterior descending coronary artery. In this article we show the case of a patient with the described coronary anomaly, presenting a severe stenosis of the circumflex artery which was successfully treated percutaneously. Besides, a proposal for updating the classification of Spindola-Franco is made, where the 4 types previously described were kept invariable, and 7 anatomical variants or subtypes were added.
