ORJUELA, Alejandro. Angioplasty of coronary sinus in left ventricle electrode implant. Rev. Colomb. Cardiol. [online]. 2011, vol.18, n.4, pp.206-211. ISSN 0120-5633.

The design of devices of cardiac stimulation in patients with dilated cardiomyopathy has become more sophisticated due to the increment of its implantation, devices that must satisfy the requirements for patients with anatomical changes that appear as a consequence of the cardiac dilation such as caliber modifications, course, length and number of coronary veins. Every time is more difficult to achieve the anatomical objectives, particularly the ideal place for the left ventricular stimulation electrode position in the coronary sinus. This situation limits in some cases the therapeutical benefit of this technique, occasionally facing to the need to submit the patient to thoracotomy for positioning the electrode in the left ventricle posterior-lateral epicardium. Thus, in order to shorten the times and morbidity and increment the implant success, we designed a strategy based on the hemodynamic technique to overcome coronary arteries obstruction and achieve through the angioplasty of the coronary sinus narrowness a more precise approach to a preselected determined epicardial vessel. We describe the technique used in the angioplasty of the coronary sinus for this purpose.
