This work presents how Peruvian citizens evaluate government efforts to implement e-government initiatives. First, the basic concepts used in the article are described, then the Peruvian e-government policy is briefly exposed, and it ends up by measuring how citizens perceive e-government and what they expect from it, through a model developed by the author during his doctoral research (Cardona, 2004). The model includes five latent and independent constructs: attitude, aptitude, confidence, relevance, and satisfaction, which affect two latent and dependent constructs: the citizen's perception and expectation regarding their interaction with public administration using information technologies and communication, under the effect of illustrative variables related to citizens, institutions and the environment.

Coronary artery disease involving chronic occlusions and bifurcation lesions continues to be a challenge for the interventional cardiologist. The improvement in the techniques has allowed a higher success rate, however, the best intervention strategy is unknown in this subgroup of patients with chronic occlusions and associated bifurcation lesions. We present the case of a patient in whom, in an angiography for study of chest pain, a chronic total occlusion and a bifurcation lesion were evidenced and were successfully treated by coronary intervention.

Advanced heart failure is a major health problem for which heart transplantation or left ventricular assist devices are the only effective treatments. Intra-aortic balloon pump inserted using femoral artery access as a bridge to heart transplantation is still frequently used, but has the disadvantage of limiting the patient’s movements, hence exposing him or her to the hazards of immobility and threatening the success of the procedure or hindering recovery. Access through the subclavian artery has become an attractive alternative since it doesn’t impair the patient’s mobility, and there is increasing evidence supporting its use. We present the first case of subclavian counterpulsation balloon implantation in a cardiovascular care center in Colombia.
