In India and México, cardiovascular diseases are the first cause of death and potential years of life lost. Close similarities exist between these two countries when facing the difficulties to establish a universal reperfusion program for ST elevation myocardial infarction (STEMI). This paper describes the situation of STEMI treatment in both countries, and examines the lessons that Mexico's health care system could adopt from the recent advances accomplished by the STEMI initiative in India.

Historical Article
[The beginning of Mexican cardiology in the springtime of the Mexican National Academy of Medicine].
The National Academy of Medicine was founded 141 years ago during the French intervention. Under the sponsorship of this brand-new medical association, Mexican cardioangiology took its first steps in the medical and surgical field as well. ⋯ These steps permitted the development of the true cardiologic speciality during 40s of the twentieth century, due to the vision of Professor Ignacio Chávez, father of Mexican cardiology. Some examples of application are the epistemologic criteria in cardiologycal domains such as the conception of Riva-Rocci's sphygmomanometer in Italy in the nineteenth century and the so-called cardiac metabolic therapy in Mexico of our time, are included.

Comparative Study
[Cox-maze III procedure for atrial fibrillation. A preliminary study].
To compare the efectiveness of the cut-and-sew Cox-maze III procedure against the Cox-maze IV peocedure by means of intraoperative bipolar radiofrequency delivery clamp. ⋯ Classic standard Cox-maze III procedure showed superiority to eliminate atrial fibrillation over the Cox-maze IV procedure made with bipolar radiofrequency ablation clamp in patients with concomitant mitral valve disease.

Transcatheter aortic valve implantation (TAVI) is currently reserved for patients with symptomatic aortic stenosis and high surgical risk. One major limiting factor related to TAVI procedural complications is conduction abnormalities and the need for permanent pacemaker implantation. ⋯ Conduction abnormalities are frequent after CoreValve® aortic valve prosthesis implantation. The incidence of new LBBB was 25%. CAVB during or post TAVI require PM implantation. New LBBB may need a closer follow up because in a 3% of the cases it may progress to CAVB.
