Transcarotid Versus Transfemoral Transcatheter Aortic Valve Replacement (from a Propensity-Matched Comparison).

Previous reports comparing transcarotid (TC) versus transfemoral (TF) approaches for patients undergoing transcatheter aortic valve replacement have had inconsistent conclusions. We compared in-hospital and 1-year clinical outcomes, changes in quality of life, and direct hospital costs for 138 TC versus 1,926 TF procedures. Propensity matching based on the Society of Thoracic Surgery Predicted Risk of Mortality was used to compare 130 patients who underwent TC with 813 patients who underwent TF. Matched TC versus TF cohorts did not differ with respect to in-hospital mortality (0.0% vs 1.4%, p = 0.380), stroke (2.3% vs 2.5%, p = 0.917), major vascular complications (0.8% vs 2.2%, p = 0.268), composite bleeding complications (4.6% vs 6.4%, p = 0.647), requirement for permanent pacemaker (14.6% vs 12.9%, p = 0.426), postoperative hospital length of stay (3.3 ± 3.4 vs 3.1 ± 3.3 days, p = 0.467), or direct hospital costs ($52,899 ± 9,560 vs $50,464 ± 10,997, p = 0.230). Similarly, at 1-year, patients who underwent TC versus patients who underwent TF did not differ with respect to all-cause mortality (7.6% vs 6.4%, p = 0.659), hospital readmission (20.0% vs 23.9%, p = 0.635), or quality of life as measured by the Kansas City Cardiomyopathy Questionnaire score (84.0 ± 17.1 vs 88.4 ± 13.9, p = 0.062). Patients who underwent TC and TF did not differ with respect to in-hospital complications, length of hospital stay, and direct hospital costs, as well as 1-year mortality, readmission, and quality of life. These data add to ongoing support for the TC approach as the optimal alternative access for patients with transcatheter aortic valve replacement deferred from a transfemoral approach.

Utility of a real-time appropriate use criteria decision support application for percutaneous coronary interventions in non-acute coronary syndrome.

OBJECTIVES: The aim of this study was to test the feasibility and value of a real-time online appropriate use criteria (AUC) application for percutaneous coronary intervention (PCI) in patients without acute coronary syndrome. BACKGROUND: High rates of non-appropriate elective PCI in the National Cardiovascular Data Registry (NCDR) CathPCI Registry have created interest in integrating decision support tools into routine clinical care to improve the frequency of appropriate PCIs. METHODS: Patients undergoing diagnostic coronary angiography and subsequent PCI for non-ACS indications at a single center were scored using a real-time AUC application pre-procedure. Blinded angiographic review was performed subsequently for each case. Rates of appropriate, inappropriate, uncertain and not rated PCIs were tabulated according to specific clinical scenarios using information available both before and after the angiographic audit. RESULTS: Of 308 PCIs in 272 patients, 196 (63.6%) were deemed appropriate, 79 (25.6%) uncertain, and two (0.6%) inappropriate; 31 (10.1%) scenarios could not be rated. With angiographic audit, inappropriate PCIs increased to 9.7%. There was a significant improvement in the rate of appropriate PCI using the real-time AUC application compared with retrospective data collection for NCDR reporting (64% vs. 53%, P = 0.01). CONCLUSIONS: Use of a real-time AUC application together with angiographic audit may improve the accuracy of reporting PCI appropriateness. © 2015 Wiley Periodicals, Inc.

Prevalence, consequences, and implications for clinical trials of unrecognized myocardial infarction.

Patients with myocardial infarction (MI) generally present with chest pain or pressure at rest or minimal exertion and have associated electrocardiographic changes and/or elevation of the biomarkers of myocardial necrosis. A subset of patients, however, experience little chest discomfort or do not present to medical attention despite experiencing symptoms. Unrecognized MI might be detected using electrocardiographic or imaging techniques, such as echocardiography, nuclear imaging, or cardiovascular magnetic resonance imaging. Unrecognized MI is a common clinical entity, with an incidence as great as 35% in high-risk populations. Moreover, the risk of a subsequent major adverse cardiovascular event might be similar to the risk after a clinically apparent MI. In the present review, we examined the incidence of unrecognized MI across broad groups of subjects and the subsequent risk of adverse cardiovascular events. Finally, we explored the potential role of including unrecognized MI as a major adverse outcome in randomized clinical trials of agents aimed at reducing cardiovascular morbidity.
