The results of PREPARE-CALC trial, presented at TCT 2018, have shown that among patients with severely calcified coronary lesions, the routine use of upfront high-speed rotational atherectomy (RA) increases stent deliverability compared with the use of balloon modification techniques such as scoring or cutting balloons (MB), with similar rates of angiographic late lumen loss and other clinical outcomes at 9 months. In his presentation in San Diego, the author, Dr. Gert Richardt emphasized that a strategy of provisional MB remained feasible, safe, and effective as long as bailout RA was readily available and offered the advantages of compatibility with smaller sized catheters and less irradiation.

In the long saga of ABSORB trials, the ABSORB IV trial presented at the TCT conference 2018 showed that polymeric coronary bioresorbable vascular scaffolds (BVS) were non-inferior to cobalt-chromium-based Xience DES for cardiovascular outcomes of target lesion failure and angina in fairly simple lesion types, with lower acute procedural success in a 1 year period. The results for this trial were published today in The Lancet. Continue reading →

The outcomes of percutaneous coronary intervention (PCI) in nonagenarians is an understudied topic. A recent observational study published in the Journal of American College of Cardiology  has looked into the time-dependent PCI trends and outcomes in 70,000 nonagenarians from 2003 to 2014 using data from the National Inpatient Sample, which is the largest longitudinal hospital inpatient database in the United States.

The results of the ULTIMATE trial, presented at the TCT conference 2018, have shown that IVUS-guided PCI is superior to angiography-guided PCI in the prevention of target vessel failure in an all-comers population. The study findings have been simultaneously published in the Journal of the American College of Cardiology. Continue reading →

The FAST-FFR study conducted by Fearon and his colleagues, and presented at the annual TCT conference 2018, has shown that Fractional Flow Reserve (FFR_angio) measured from the coronary angiogram alone has a high sensitivity, specificity and accuracy compared with pressure-wire derived Fractional Flow Reserve (FFR). The results of this study were published ahead of print in Circulation. Continue reading →

Results from a subgroup analysis of the TriValve Registry presented at TCT 2018 showed that interventional tricuspid edge-to-edge valve repair was safe with improvement in outcomes in patients, with high procedural success rates. Continue reading →

Results from an open-label, multi-center, 2×2 factorial design randomized trial powered for equivalence, comparing the self-expanding Corevalve Evolut R valve to balloon expandable Edwards Sapien 3 valve, have shown that the two valves were equivalent to each other in terms of decreasing all-cause mortality, stroke, moderate or severe prosthetic valve regurgitation, and permanent pacemaker implantation (p=0.02). Trial results presented at the 2018 TCTMD conference held at San Diego, California, also showed equivalence in a comparison between general anesthesia vs local anesthesia (with conscious sedation) in terms of decreasing all-cause mortality, stroke, myocardial infarction, infection requiring antibiotic treatment, and acute kidney injury (p=0.02).

The spectacular results of the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) trial, presented at TCT 2018, show that transcatheter mitral valve approximation using the MitraClip, on a background of maximally tolerated guideline-directed medical therapy (GDMT) was superior to GDMT alone in the reduction of Heart Failure (HF) hospitalization and mortality in symptomatic HF patients with grade 3-4+ Mitral regurgitation (MR). These landmark findings were simultaneously published today in the New England Journal of Medicine. Continue reading →

Polymer-free amphilimus-eluting stents (PF-AES) are non-inferior to permanent-polymer zotarolimus-eluting stents (PP-ZES) in terms of target-lesion failure at 12 months, according to the results of the ReCre8 study, presented by Pieter R. Stella, MD, Ph.D. (University Medical Center, Utrecht, the Netherlands) at TCT 2018. The results for the first RCT comparing PF-AES versus latest generation PP ZES in an all-comers PCI population were simultaneously published in Circulation. Continue reading →

A randomized global, prospective, multi-center, single-blind trial comparing the Eluvia paclitaxel-eluting stent (Boston Scientific) to  Zilver PTX paclitaxel-eluting stent (Cook Medical) has shown that the Eluvia stent outperformed Zilver in terms of efficacy, which was defined as primary patency at 12 months. These findings, published in The Lancet, were presented by Dr. William Gray at the annual TCT 2018 conference held in San Diego today. Continue reading →

Findings from the SORT-OUT trial, presented at the 30^th annual Transcatheter Cardiovascular Therapeutics (TCT) conference 2018 held at San Diego, showed that at 12 months, polymer free Biolimus A9-coated BioFreedom stent was non-inferior to the thin strut, biodegradable polymer cobalt-chromium sirolimus-eluting Orsiro stent in an all-comers patient population. Continue reading →

Results of two studies published in the latest issue of the JAMA have focussed on the syndrome of physician burnout and rates of career choice regret within the US medical establishment. While findings from one study showed that a high prevalence of symptoms of burnout was present with substantial variation with differing specialties, a systematic review found marked variation in the prevalence estimates of burnout among physicians and inconsistency in burnout definitions, thereby underscoring the dilemmas in the assessment of this fast-growing problem.

The discovery of Valsartan products that were contaminated with NDMA, in July 2018, in drug products manufactured in China, triggered the withdrawal of all affected products by medical agencies across Europe and the United States. Being one of the most well characterized and potent animal carcinogens known, Pottegard and his colleagues conducted an expedited observational cohort study using the nationwide Danish healthcare registry. They aimed to quantify the potential effects of NDMA contaminated valsartan products in terms of increased cancer risk, in order to provide timely information for regulatory bodies evaluating its carcinogenic effects. Results from this Danish cohort study, published in the BMJ, however, failed to show a significant increase in overall short-term cancer risk due to consumption of NDMA contaminated valsartan.

Findings from a Danish nationwide registry conducted among patients with Atrial Fibrillation (AF), initiated on Vitamin K Antagonists (VKA) for stroke prevention between 1997 and 2011, found that almost one-half of patients with prior good level of VKA control (TTR ≥70%) had TTR <70% during the following year. Additionally, those with a prior TTR of ≥70% had a limited long-term prognostic value for stroke, thromboembolism or major bleeding risk, according to the online publication in JACC.

Findings from an international TAVR registry involving 16 centers and spanning over a decade have important implications for operator training and patient care at centers performing TAVR. The study, published in JACC Cardiovascular Interventions, is a testament to the learning curve that still exists with both greater procedural safety and lower mortality rates reported when TAVR is performed by experienced operators. Additionally, TAVR performed at low annual volume (<50 procedures) institutions is associated with decreased procedural safety and higher patient mortality. This stepwise improvement in patient outcomes bears important implications for operator training and patient care at centers performing TAVR. Continue reading →
