Myocardial Revascularization Surgery Hits a Plateau

Myocardial Revascularization Surgery Hits a Plateau

Hopes were raised high by the ARTS study, when set to show the benefit of bilateral internal mammary arteries (BIMA) during coronary artery bypass graft surgery compared over the use of a single internal mammary artery (SIMA) at 10 year follow up, but only one sub-study was able to show an advantage over radial grafts.

perforación coronaria en angioplastia

Practical Management of Coronary Perforations

Coronary perforation has an incidence of 0.5% and it is associated with a 13-fold increase in in-hospital events and a 5-fold increase in 30-day mortality. This event is so catastrophic that its management has become indispensable knowledge to all interventional cardiologists. This accident is most frequently provoked by artery over-dilation caused by a balloon or

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

iFR Assessment of Intermediate Aortic Stenosis Lesions Consolidates

Once a big void that prevented us from effectively assessing functional compromise, intermediate aortic stenosis has made us treat many lesions “just in case”, to save us what would be a complicated procedure, had a valve been placed. Auspiciously, some light has been shed by several, most welcome, studies simultaneously published in J Am Coll

¿Qué usar para medir funcionalmente una lesión coronaria en el contexto de estenosis aórtica severa?

What Should We Use for the Functional Assessment of Coronary Lesions in Severe Aortic Stenosis?

This systematic analysis measured intracoronary pressure in different phases of the cardiac cycle and flow velocity in patients with severe aortic stenosis and coronary artery disease, who were scheduled for transcatheter aortic valve replacement (TAVR). The aim was to determine the impact of aortic stenosis on: 1) flow, at different phases; 2) hyperemic coronary flow;

El alta en el mismo día luego de una angioplastia coronaria es cada vez más popular pero todavía no es regla

Discharge During the Weekend After Cardiac Surgery Is Not Associated with Readmissions

According to this new work (soon to be published in Ann Thorac Surg), discharging a patient during the weekend or a holiday after cardiac surgery is not associated with higher rates of readmission compared with patients discharged during weekdays. A total of 4877 patients were discharged after cardiac surgery in high-volume sites in the United States. Among them,

Nuevo dispositivo para medición del FFR permite cruzar la lesión con nuestra guía preferida

Safety of Lesion Deferral with iFR or FFR in Both Stable and Acute Patients

Overall, deferral of lesion revascularization is equally safe with both fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR), with a low rate of events of about 4%. Lesions were more frequently deferred when iFR (as opposed to FFR) was used for functional assessment. Among patients with deferred lesions, acute patients experienced significantly more events

TCT 2018 | CorMicA trial: función coronaria en pacientes con angina y coronarias normales

TCT 2018 | CorMicA Trial: Coronary Function in Patients with Angina and Normal Coronary Arteries

Angina pectoris without stenosis in the epicardial coronary arteries is a common problem with several possible underlying causes. The main purpose of this work was to test the hypothesis that stratified medical therapy guided by an interventional diagnostic procedure might improve outcomes. Patients without coronary lesions and with angina were immediately randomized 1:1 to an

TCT 2018 | OAC-ALONE: solo anticoagulación luego del año de un stent en pacientes fibrilados

TCT 2018 | OAC-ALONE: Anticoagulation Alone 1 Year After Stenting in Patients with Atrial Fibrillation

Up to now, there had been no randomized controlled trial assessing oral anticoagulation alone vs. oral anticoagulation plus antiplatelet therapy in patients with atrial fibrillation 1 year after stenting in a setting of stable coronary disease. Such was the vacuum that this work, presented at TCT 2018 and published simultaneously in Circulation, attempted to fill. This trial

TCT 2018 | FAST-FFR: FFR derivado de la angiografía, sin hiperemia y sin necesidad de cruzar la lesión

TCT 2018 | FAST-FFR: Angiography-Derived FFR Without Hyperemic Stimulus or Invasive Guidewire Placement

All over the world, functional lesion measurement remains underutilized due to the need for a hyperemic stimulus (which may be avoided with instantaneous wave-free ratio [iFR]) and, above all, the invasiveness of guidewire placement (crossing the intended lesion) for the measurement. These guidewires have improved a lot, but they still lack the navigating capacity of

TCT 2018 | ULTIMATE: Implante de DES guiado por IVUS, para todos los vasos, para todas las lesiones

TCT 2018 | ULTIMATE: IVUS Guided DES Implantation for All Vessels, for All Lesions

Intravascular Ultrasound (IVUS) guided drug eluting stent (DES) implantation is associated with less adverse events compared against angiography guided stenting. This is especially clear for certain populations (with left main PCI as paradigmatic) but not so clear when dealing with all comers. 1448 all comer patients requiring DES stenting were randomized 1:1 to IVUS guided
