El uso de imágenes intravasculares para guiar la angioplastia reduce el riesgo de muerte cardiovascular en comparación con la angiografía

The Use of Intravascular Imaging to Guide PCI Reduces Cardiovascular Death Risk, Compared to Angiography

Intravascular imaging, which includes ultrasound intravascular (IVUS) and optical coherence tomography (OCT), shows live details that better characterize post stenting plaque, anatomy and outcomes.  The already familiar limitations of the angiography has lead us to think that IVUS and OCT could improve clinical outcomes; however, we should still find the evidence to support this claim.

¿Podría el FFR ser reemplazado para la evaluación fisiológica de una lesión intermedia?

Physiologically Assessing Intermediate Stenosis: Could FFR Be Replaced?

Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are commonly used to assess physiological severity of angiographically intermediate stenosis. Both indexes quantify a pressure ratio as subrogate to measuring flow, which is much harder to do. Discordance between FFR and iFR occurs in up to 20% of cases, which should not be a matter<a href="https://solaci.org/en/2018/01/14/physiologically-assessing-intermediate-stenosis-could-ffr-be-replaced/" title="Read more" >...</a>

El desarrollo de las nuevas válvulas disminuye la necesidad de marcapaso

Development of New Valves Lowers Need for Pacemaker

Courtesy of Dr. Carlos Fava. While the benefits of TAVR are well-known, the need for a permanent pacemaker after implantation is still an issue to solve, even though new valves have reduced it. This study enrolled 175 patients who underwent TAVR with an ACURATE neo TF valve. In this population, 58% of patients were women and the<a href="https://solaci.org/en/2018/01/11/development-of-new-valves-lowers-need-for-pacemaker/" title="Read more" >...</a>

Radioprotection: 6 essential articles to keep you updated

1) On Radiation Protection: Editorial comment by Dr. Ariel Durán I am pleased to witness the increased amount of scientific papers in high impact journals addressing topics related to radiation protection or the harmful effects of radiation on our patients and primary or secondary operators.

El costo clínico y el costo económico compiten en la desescalada de antiagregantes

Clinical and Economic Costs Compete in the De-Escalation of Antiplatelet Therapy

Patients undergoing primary angioplasty for ST-segment elevation acute myocardial infarction have similar clinical outcomes at 1 year regardless of whether they are treated with ticagrelor or prasugrel, according the PRAGUE-18 study. This new substudy adds an interesting detail: patients who switched from prasugrel and ticagrelor to clopidogrel, citing economic reasons for the “de-escalation” of therapy, were<a href="https://solaci.org/en/2018/01/03/clinical-and-economic-costs-compete-in-the-de-escalation-of-antiplatelet-therapy/" title="Read more" >...</a>

iFR en lesiones no culpables: el momento de la medición parece cambiar la historia

iFR in Nonculprit Lesions: Measurement Timing May Change History

During primary angioplasty, it is not uncommon to see several other lesions in coronary arteries. Current guidelines advise against the treatment of these lesions in the same primary angioplasty procedure, although there is evidence supporting such a course of action that may warrant changes in these recommendations. The functional assessment of these nonculprit lesions may<a href="https://solaci.org/en/2017/12/19/ifr-in-nonculprit-lesions-measurement-timing-may-change-history/" title="Read more" >...</a>

Clopidogrel or Ticagrelor in Patients with Acute Coronary Syndrome Treated with New-Generation DES: CHANGE DAPT

Courtesy of Dr. Pablo Baglioni. This is a prospective observational study with a 1-year follow-up analyzing 2062 patients with acute coronary syndrome (ACS) who have been treated with coronary angioplasty using new-generation drug-eluting stents (DES). Patients were included between December 21, 2012 and August 25, 2015. On May, 2014, due to changes in international guidelines, clopidogrel<a href="https://solaci.org/en/2017/12/15/clopidogrel-or-ticagrelor-in-patients-with-acute-coronary-syndrome-treated-with-new-generation-des-change-dapt/" title="Read more" >...</a>

¿Cómo afecta el implante de endoprótesis a la función renal?

How Is Renal Function Affected by Endoprosthesis Implantation?

The occurrence of renal failure after any endovascular intervention is associated with increased morbility and mortality. After a coronary intervention (whether it be angioplasty or surgery), renal failure increases mortality 20-fold. Relatedly, surgical repair of an abdominal aortic aneurysm with renal failure is also associated with a significant increase in the number of events.
