There is no such thing as coincidence, at least not for the evidence-based medical science. This is what the NOBLE 5-year outcomes, soon to be published in the Lancet, seem to say, in line with the BBC exposé of the EXCEL study. The NOBLE study randomized patients with left main disease to compare PCI vs…
Latest Guidelines “Dropped” After Scandal Over EXCEL Results
The European Association for Cardio-Thoracic Surgery (EACTS) formally withdrew its support for the latest coronary revascularization guidelines following a BBC investigation suggesting that data from the EXCEL trial might have been manipulated. The recommendations for left main coronary artery revascularization featured in the 2018 guidelines, which were written jointly with the European Society of Cardiology…
The EXCEL Authors’ Answer to the BBC Investigation
Do to an investigation carried out by the BBC that led to the withdrawal of EACTS support from the latest coronary revascularization guidelines, the authors of the EXCEL study (indicated by this research) provided the following answers. -Defining Peri-Procedural Infarction: All researchers involved (including surgeons) agreed that the universal definition of infarction was not right…
TCT 2019 | EXCEL: Left Main Coronary Artery Angioplasty with Favorable Results at 5 Years
Courtesy of Dr. Carlos Fava. Unprotected left main coronary artery angioplasty with drug-eluting stents has emerged as an acceptable strategy for a select group of patients, with results comparable to those of myocardial revascularization surgery at 2 or 3 years. However, beyond such term, we had no valid information. Researchers analyzed the 5-year follow-up results for the…
TCT 2019 | IDEAL-LM: Bioabsorbable Polymer DES vs. Permanent Polymer DES for Left Main Stenosis
Courtesy of SBHCI. This study showed that using the everolimus eluting stent with bioabsorbable polymer Synergy followed by 4 months of dual antiplatelet therapy (DAPT) to treat left main stenosis (LMS) was safe and effective, compared against using the everolimus eluting stent with permanent polymer Xience followed by the conventional 12 months DAPT. This study…
Calcium Scoring: “Location” Seems to Be More Important than “Percentage”
The presence of a high percentage of calcium in the left main coronary artery is independently associated with a 20–30% greater risk for cardiovascular and all-cause death in asymptomatic adults. This highlights the fact that calcium location, and not only amount, is important. Calcium scoring reports from computerized tomography (CT) usually inform only that: how…
Peri-Procedural Infarction in Angioplasty vs. Surgery in the Left Main Coronary Artery
According to the EXCEL trial, peri-procedural infarction was more common after left main coronary artery surgery compared with angioplasty, and it was strongly associated with increased 3-year mortality after controlling all possible confounding variables. This increased mortality was only present in extensive infarctions with an increase in CK-MB ≥10×. The EXCEL trial seems to want…
Outcomes of MAIN-COMPARE: A 10-Year Follow-Up for a Historical Rivalry
Angioplasty and myocardial revascularization surgery have competed over the left main coronary artery for a long time. There may be many points of view involved in the interpretation of trial outcomes. While surgeons consider the left main coronary artery to be suitable for surgery (except when faced with surgical contraindications), interventional cardiologists see the left…
EXCEL Outcomes: PCI vs CABG in Patients with Prior Cerebrovascular disease
Most certainly, as we read this title, we imagine the conclusion (as does the editor): patients with prior cerebrovascular disease (CEVD) benefit from a less invasive revascularization strategy, such as PCI. However, the EXCEL outcomes tell us that patients with left main coronary artery disease (LMCAD) and a history of CEVD will not benefit from…
Left Main PCI Technique Could Change DAPT Duration
Up to 20% of patients undergoing left main PCI require a 2-stent technique, and this number should most likely grow after the DKCRUSH-V outcomes. However, this study contradicts the DKCRUSH-V and brings us back to “the simpler the better”, since patients undergoing 1 stent left main PCI presented less revascularization and less target vessel failure…
Radial Access Is Always Preferred, Even for Treatment of the Left Main Coronary Artery
The potential need for a 7-Fr guidewire, the use of several coronary guidewires and/or a kissing balloon, and the requirement of indispensable monitoring by intravascular ultrasound (IVUS) have been used by some interventional cardiologists as excuses to resist radial access. In that sense, left main coronary artery angioplasty was the last stand of femoral access.…
