Study Suggests ICU Care May Be Overutilized in Stable STEMI Patients

A study led by Dr. Jay S. Shavadia published in JACC: Cardiovascular Interventions showed that although more than 80% of stable patients with an ST-elevation myocardial infarction (STEMI) were treated in the intensive care unit (ICU), the risk of developing a complication requiring ICU care was around 16%. These findings suggest that implementing a risk-based triage strategy could be a better alternative to the current strategy where patients with STEMI are typically admitted to the ICU.

Randomized Trial Shows That Transcatheter Aortic-valve Replacement is Non-inferior to Surgery in Low Risk Patients

A study by Dr. Jeffrey Popma and colleagues published in the New England Journal of Medicine showed that transcatheter aortic-valve replacement (TAVR) was non-inferior to surgery with respect to death or the occurrence of a disabling stroke by 24 months in the low-risk group of patients with aortic stenosis. Previous studies showed that in patients with severe aortic stenosis who were at high risk of complications or death from surgery, TAVR with a self-expanding supra-annular bioprosthesis had better outcomes than medical therapy or surgery. However, there was not enough evidence to advocate the use of TAVR instead of surgery in a younger, healthier population. The authors aimed to address this knowledge gap through this study.

Is the Improvement in Fractional Flow Reserve After Percutaneous Coronary Intervention (ΔFFR) Associated With Clinical Outcome and Symptomatic Relief?

In an analysis of two randomized clinical trials published in JAMA cardiology, Fournier et al. reported that the larger the improvement in FFR, the larger the symptomatic relief and the lower the event rate. This was suggestive of the fact that measuring FFR before and after PCI could provide clinically useful information. Continue reading

DECISION-CTO Demonstrates No Significant Difference in Death, MI, Stroke, or Any Revascularization with CTO PCI vs. No CTO PCI

The results of the DECISION-CTO trial conducted by Lee et al. showcased that CTO-PCI was feasible with high success rates. In addition to this, there was no difference in the incidence of major adverse cardiovascular events with CTO PCI vs. no CTO-PCI, however, the study was limited by low power for clinical endpoints and high crossover rates between groups. The results were published online in Circulation. Continue reading

Early and Late Leaflet Thrombosis Following TAVR A Multicenter Initiative From the OCEAN-TAVI Registry

A real-world multicenter study by Yanagisawa and his colleagues published in Circulation: Cardiovascular Interventions reported that untreated early leaflet thrombosis did not affect the cumulative event rates of death, stroke, and rehospitalization for heart failure.

Prior Cerebrovascular Disease: A Key Factor In The Assessment for Optimal Left Main Coronary Artery Revascularization Strategy Results From the EXCEL Trial

A study conducted by Dr. Gregg W.Stone and his colleagues from Columbia University Medical Center demonstrated that patients with left main coronary artery disease (LMCAD) and prior cerebrovascular disease (CEVD) compared with those without CEVD have higher rates of stroke and reduced event-free survival after revascularization. In their publication in JACC: Cardiovascular Interventions, they stated that PCI need not be a priori preferred over CABG for LMCAD in patients with known CEVD.  Patients with CEVD should undergo evaluation for both PCI and CABG, with careful consideration of comorbidities, the likelihood of safely achieving complete revascularization, and patient preferences in order to determine the optimal coronary revascularization strategy.
