Guidelines recommend oral anticoagulation for all ≥ 75-year-old patients with atrial fibrillation. However, there is little evidence as to its net clinical benefit in the elderly population. This study looked at the life net clinical benefit in atrial fibrillation patients over 75 years of age treated with warfarin or apixaban vs. no treatment. Researchers observed…
Percutaneous Annuloplasty in Functional Mitral Regurgitation vs. Sham Procedure
In cases where it is difficult to demonstrate the improvement of a drug or a device in hard endpoints such as mortality, we should look for softer and easier to prove endpoints. The problem is that these soft endpoints are often subjective (such as sensation of shortness of breath or angina pectoris) and they could…
Unilateral Vascular Access in TAVR: Our Main Procedure, Increasingly Minimalist
There has been a significant decline in vascular complications in the last few years due to improvements in device profiles and operator experience on transcatheter aortic valve replacement (TAVR). Unilateral vascular access for transfemoral TAVR is as safe as bilateral access and it could be more comfortable for patients according to this study recently published…
Off-hours Primary PCI Still Have the Highest Mortality Rate?
According to this contemporary study, in the current organized STEMI network, patients admitted to a tertiary high-volume center for primary PCI are managed similarly and have similar prognosis regardless admission time. Several prior studies have shown primary PCI during off-hours (6 pm to 8 am) had worse outcomes vs. on-hour interventions (8 am to 6…
International Consensus to Prevent Radial Artery Occlusion After Interventions
This study provides the steps to follow in order to prevent or at least reduce radial artery occlusion after using it as an access for a diagnosis or treatment study. The use of transradial access is exponentially increasing worldwide due to its lower chance of bleeding events and vascular complications than transfemoral access. Radial artery…
Net Benefit of Left Atrial Appendage Closure vs. Anticoagulation in Atrial Fibrillation
This analysis shows that the long-term clinical benefit of left atrial appendage closure with Watchman is superior to warfarin in patients with atrial fibrillation (AF). The initial peri-procedural risks of device implantation are counterbalanced over time, with reduced risk of bleeding and death. The PROTECT-AF (Watchman Left Atrial Appendage Closure Technology for Embolic Protection in…
Pre-TAVR Revascularization: Angiographic or Physiological?
In patients undergoing transcatheter aortic valve replacement (TAVR), fractional flow reserve (FFR) guided revascularization is associated with favorable results compared against the traditional angiography guided revascularization. Given the complete lack of randomized studies, this observational study is the best we have to decide how to guide revascularization in patients with symptomatic severe aortic stenosis undergoing…
AHA 2019 | COMPLETE: Complete Revascularization Is Superior since It Treats Other Vulnerable Plaque
This COMPLETE sub-study using optical coherence tomography (OCT) showed the prevalence of vulnerable lesions other than the culprit which should provide a physiopathological explanation of the benefit of complete revascularization observed in the original study. STEMI patients with multivessel disease will benefit from complete revascularization in terms of reduced cardiovascular death and repeat MI according…
AHA 2019 | Treat Stroke to Target: Post-Stroke Aggressive Therapy with Statins
Indicating statins to reach more aggressive LDL goals in patients that have suffered transient ischemic attack or ischemic stroke driven by atherosclerosis significantly reduces major cardiovascular events according to this study presented in the AHA 2019 scientific sessions simultaneously published in NEJM. The study was prematurely ended because of lack of funding, but its outcomes…
Lower Mismatch Rate with the New Self-Expandable Valves
Prosthesis mismatch (PPM) was introduced by Rahimtoola in 1978 and happens when the effective orifice area of a heart valve prosthesis is too small in relation to patient body size. Surgical valves have been well documented, but there is little information on percutaneous valves. The study looked at 757 patients undergoing TAVR with pre and post procedural eco-Doppler…
