ABSTRACT
O transplante de células-tronco é uma nova terapia com objetivo de produzir regeneração cardíaca pela diferenciação ou aumento dos miócitos cardíacos ou proliferação neovascular em pacientes no estágio final de insuficiência cardíaca congestiva secundária a cardiomiopatia dilatada¹, mas os resultados são desconhecidos2,3.
Stem cell transplantation is a new therapy applied to produce cardiac regeneration through differentiation or increase of heart myocytes or neovascular proliferation in patients in the end stage of congestive heart failure secondary to dilated cardiomyopathy¹, but the results are still unknown2,3.

We report a rare case of anomalous origin of the left coronary artery from the pulmonary trunk in a 45-year-old woman. The approach and technique used for selective catheterization of an anomalous left coronary artery arising from the pulmonary trunk are described. Six years after diagnosis, echocardiography showed left ventricular disfunction, and surgical treatment was indicated again. The origin of the left coronary artery from the pulmonary trunk was closed, and the postoperative period was uneventful, with recovery of left ventricular function and disappearance of ischemic features on stress myocardial perfusion imaging with 99m Tc-sestamibi, performed 4 weeks after surgery
