  • Computer programming for clinicians: five steps to your new favourite skill. Part 2
    by Chow, J.-J. on October 28, 2020 at 9:00 am

    In the previous edition of Cardiology in focus you read about setting yourself up to learn computer programming. In this article we discuss the learning process and consolidating a useful portfolio of skills for clinical projects: steps 3–5 of 5. Step 3: get stuck inThere is no substitute for tackling a problem yourself to understand how your new tools work. If you are lucky enough to have data ready from your own project, use these. Otherwise, you can download ready prepared data sets like Iris (measurements of flowers) or Titanic (passenger demographics from the doomed boat) to try functions on. Like learning a foreign language, regular use of your new skill in a variety of situations will grow your abilities faster than sporadic, narrow usage. This is the moment where you will start to shift into a programmer’s mindset. Unlike a human colleague, a computer has almost...

  • Cerebrovascular events after transcatheter mitral valve interventions: a systematic review and meta-analysis
    by Chateauneuf, G., Nazif, T. M., Beaupre, F., Kodali, S., Rodes-Cabau, J., Paradis, J.-M. on October 28, 2020 at 9:00 am

    ObjectiveCurrent guidelines support the use of transcatheter mitral valve interventions to treat some selected high-risk patients with significant mitral valvulopathy. As with any other interventional cardiac procedure, concerns have been raised about cerebrovascular event. The aim of this systematic review and meta-analysis was to determine the incidence of cerebrovascular events following (1) transcatheter mitral valve edge-to-edge repair with mitral valve clip and (2) transcatheter mitral valve replacement (TMVR). MethodsWe conducted a systematic review of studies reporting the cerebrovascular adverse events after transcatheter mitral valve edge-to-edge repair and TMVR procedures. The primary endpoint was the incidence of cerebrovascular events as defined by the Mitral Valve Academic Research Consortium. An event that occurred within 30 days or during index hospitalisation was defined as periprocedural; otherwise it was defined as non-periprocedural. This study was designed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Aggregated study-level data were pooled using a random effect model. The quality of each study was appraised with the Hawker checklist, a method of systematically reviewing research from different paradigms. ResultsSixty studies totalling 28 155 patients undergoing edge-to-edge repair with mitral valve clip were included in the analysis. Periprocedural stroke and non-periprocedural stroke rates were 0.9% (95% CI 0.6 to 1.1) and 2.4% (95% CI 1.6 to 3.2), respectively. For TMVR procedures, 26 studies including 1910 patients were analysed. The estimated periprocedural stroke incidence was 1% (95% CI 0.5 to 1.8) compared with 7% (95% CI 0.8 to 18.5) for non-periprocedural stroke. ConclusionsTranscatheter mitral valve interventions are associated with low rates of cerebrovascular events. The exact mechanisms of these complications are still poorly understood given the relative paucity of good quality data. Trial registration numberCRD42019117257.

  • Imaging assessment of mitral and aortic regurgitation: current state of the art
    by Steeds, R. P., Myerson, S. G. on October 28, 2020 at 9:00 am

    Learning objectives To understand the advantages and disadvantages of imaging techniques in identifying aetiology and mechanisms of mitral and aortic regurgitation. To understand the key echocardiographic methods of quantifying severity of mitral regurgitation (MR) and aortic regurgitation (AR), and their advantages and limitations. To be aware of the relative advantages and disadvantages of cardiac magnetic resonance in quantifying severity of MR and AR. IntroductionValvular heart disease (VHD) affects 1 in 50 of the general population and 1 in 3 of the over 65s, and is associated with increased morbidity and premature mortality.1 Among adults presenting to hospital with severe VHD, mitral regurgitation (MR: 21.3%) is the second and aortic regurgitation (AR: 5.3%) is the third most common valve lesion after aortic stenosis (41.2%).2 The predominance of MR above AR is also found in community-based studies, although it...
