Results of a randomized trial presented at TCT 2019 and simultaneously published in The Lancet, showed that TAVR with the self-expanding ACURATE neo (Boston Scientific) did not meet non-inferiority compared to the balloon-expandable SAPIEN 3 (Edwards Lifesciences) in terms of early safety and clinical efficacy outcomes.
Meta-analysis Shows Reduced 1-Year Mortality with TAVR in Low-Risk Severe AS Patients
In a meta-analysis of RCTs comparing TAVR (Transcatheter Aortic Valve Replacement) versus SAVR (Surgical Aortic Valve Replacement) in low-risk patients with severe AS, TAVR was associated with a significantly lower risk of all-cause and cardiovascular mortality at 1 year follow up. The study conducted by Kolte et.al was recently published in the Journal of American College of Cardiology.

SYNTAXES Study: No Significant Difference In All-Cause Death At 10 Years Between PCI and CABG Results of a 10-year Follow-up Study presented at the European Society of Cardiology (ESC) Congress 2019
A follow-up of a multicenter, randomized controlled trial, the results of which were debuted at the European Society of Cardiology (ESC) Congress 2019, has shown that at 10 years, no statistically significant difference existed in all-cause mortality between percutaneous coronary intevention (PCI) using first-generation paclitaxel-eluting stents and coronary artery bypass grafting (CABG). However, CABG was shown to provide significant survival benefit in patients with three-vessel disease, but not in patients with left main coronary artery disease.

Nationwide Study Shows New-onset Left Bundle Branch Block After Transcatheter Aortic Valve Replacement Occurred in 15% of Intermediate Risk Patients and Is Associated with Worse 2 Year Outcomes
According to a new nationwide study, new onset left bundle branch block (LBBB) post transcatheter aortic valve replacement (TAVR), a recently established therapy for intermediate risk surgical candidates with symptomatic, severe aortic stenosis, is associated with adverse long term clinical outcomes in patients without baseline conduction disturbances or pacemaker. Based on the findings published in the European Heart Journal, these outcomes include cardiovascular mortality, re-hospitalization, new pacemaker implantation, and worsened left ventricular systolic function in intermediate risk patients.
STS/ACC TVT Registry: Higher Volume Associated with Better TAVR Outcomes
Recent updates from the Centers for Medicare & Medicaid Services (CMS) maintain the volume requirements of the transcatheter aortic-valve replacement (TAVR) programs to qualify for reimbursement. In corroborate with the CMS updates, the latest data from the Society of Thoracic Surgeons/American College of Cardiology (STS/ACC) Transcatheter Valve Therapy (TVT) Registry by Dr. Sreekanth Vemulapalli et al., published in the New England Journal of Medicine, revealed lower 30-day mortality at hospitals with a high procedural volume.
MR-INFORM: Myocardial Perfusion Based Strategy to Determine Need for Revascularization Shown to be Non-Inferior to Invasive Angiography in Reducing the Occurrence of Major Adverse Cardiovascular Events in Patients with Stable Angina
A trial led by Dr. Eike Nagel published in the New England Journal of Medicine showed that among patients with stable angina and risk factors for coronary artery disease, a myocardial-perfusion cardiovascular MRI based strategy to determine eligibility for revascularization was associated with a lower incidence of coronary revascularization than invasive angiography with fractional flow reserve (FFR) and was non-inferior to FFR in terms of the occurrence of major adverse cardiovascular outcomes.
LRT Trial: Transcatheter Aortic Valve Replacement In Low Risk Patients with Symptomatic Severe Aortic Stenosis Appears To Be Safe At 1 Year
A study led by Dr. Ronald Waksman showed that in low-risk patients with symptomatic severe aortic stenosis, transcatheter aortic valve replacement (TAVR) appears to be safe at 1 year. This study, which was published in JACC Cardiovascular Interventions, provides evidence to support the use of TAVR in low-risk patients.
BIO-RESORT TRIAL: Lower Stent Strut Thickness Associated with Lower Rates of Repeat Revascularization
A prespecified analysis of the BIO-RESORT trial demonstrated that patients stent in small coronary vessels were less likely to need repeat revascularization if ultrathin-strut sirolimus-eluting stents were used as compared to the previous generation thin strut zotarolimus-eluting stent. Dr. Rosaly Buiten, the lead authors of this study published in JAMA cardiology, highlights the need to further evaluate the potential benefit of thin stent struts.

A study led by Dr. Robert Yeh that was published in JACC: Cardiovascular Interventions showed that in the setting of chronic total occlusion (CTO), patients with depression had more significant angina before percutaneous coronary intervention (PCI). However, these patients also had a greater improvement in health status after PCI.
