Abstract

GUTIERREZ JAIKEL, Luis  and  ALVARADO RUIZ, Marco Antonio. Seguimiento a un año de la revascularización percutánea de oclusiones coronarias crónicas en el Hospital México. Rev. costarric. cardiol [online]. 2020, vol.22, n.1, pp.41-47. ISSN 1409-4142.

There is a high prevalence of complex coronary artery disease worldwide, in this group chronic total occlusions (CTO) generate a great burden of disease in the population and are a difficult therapeutic challenge. In recent years and with the development of new technologies, the world have seen a benefit in quality of life, symptoms and systolic function of the left ventricle when performing a percutaneous coronary intervention (PCI) of CTO with high success rate and low rate of complications. In this study we describe the cardiovascular clinical results one year after performing PCI in patients with CTOs in Hospital Mexico in Costa Rica during 2016-2017.

Methods:

We registry 54 patients completing one year follow up after PCI of CTO. We measure sociodemographic and clinical variables quantifying symptoms using NYHA and CCS scales, ejection fraction (EF) using echocardiography previous and after PCI, and the complications developed.

We identified 54 patients who underwent PCI of CTO, most were men with an average age of 64 years and a basic academic level. There was no significant difference in the pre-and-post-procedure EF (p=0.68), with a trend to improvement in patients with severe left ventricle systolic dysfunction and viable myocardium. There were significant differences in symp- tom improvement based on the NYHA functional status score (p<0.01) and the CCS angina score (p<0.01). A successful procedure was achieved in 96.3% of cases with no significant difference depending on vascular access or the J-CTO scale with low complication rate.

Conclusions:

There is a significant clinical benefit based on symptoms of performing PCI in patients with CTO with a high success rate in the procedure and a few associated complications.
