In patients with stable coronary artery disease (CAD), decisions regarding revascularisation are primarily driven by the severity and extent of coronary luminal stenoses as determined by invasive coronary angiography. More recently, revascularisation decisions based on invasive fractional flow reserve (FFR) have shown improved event free survival. Cardiovascular magnetic resonance (CMR) perfusion imaging has been shown to be non-inferior to nuclear perfusion imaging in a multi-centre setting and superior in a single centre trial. In addition, it is similar to invasively determined FFR and therefore has the potential to become the non-invasive test of choice to determine need for revascularisation.

Transcatheter aortic valve implantation (TAVI) is a proven treatment for life-threatening aortic valve disease, predominantly severe aortic stenosis. However, even among developed nations, access to TAVI is not uniform. The Valve for Life initiative was launched by the European Association of Percutaneous Cardiovascular Interventions in 2015 with the objective of improving access to transcatheter valve interventions across Europe. The UK has been identified as a country with low penetration of these procedures and has been selected as the fourth nation to be included in the initiative. Specifically, the number of TAVI procedures carried out in the UK is significantly lower than almost all other European nations. Furthermore, there is substantial geographical inequity in access to TAVI within the UK. As a consequence of this underprovision, waiting times for TAVI are long, and mortality among those waiting intervention is significant. This article reviews these issues, reports new data on access to TAVI in the UK and presents the proposals of the UK Valve for Life team to address the current problems in association with the British Cardiovascular Intervention Society.

Objective To define the incidence and risk factors for infective endocarditis (IE) following surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI). Methods All patients who underwent first SAVR or TAVI in England between 2007 and 2016 were identified from the NICOR databases. Hospital admissions with a primary diagnosis of IE were identified by linkage with the NHS Hospital Episode Statistics database. Approval was obtained from the NHS Research Ethics Committee. Results 2057 of 91 962 patients undergoing SAVR developed IE over a median follow-up of 53.9 months—an overall incidence of 4.81 [95% CI 4.61 to 5.03] per 1000 person-years. Correspondingly, 140 of 14 195 patients undergoing TAVI developed IE over a median follow-up of 24.5 months—an overall incidence of 3.57 [95% CI 3.00 to 4.21] per 1000 person-years. The cumulative incidence of IE at 60 months was higher after SAVR than after TAVI (2.4% [95% CI 2.3 to 2.5] vs 1.5% [95% CI 1.3 to 1.8], HR 1.60, p<0.001). Across the entire cohort, SAVR remained an independent predictor of IE after multivariable adjustment. Risk factors for IE included younger age, male sex, atrial fibrillation, and dialysis. Conclusions IE is a rare complication of SAVR and TAVI. In our population, the incidence of IE was higher after SAVR than after TAVI.

Objectives To understand the impact of COVID-19 on delivery and outcomes of primary percutaneous coronary intervention (PPCI). Furthermore, to compare clinical presentation and outcomes of patients with ST-segment elevation myocardial infarction (STEMI) with active COVID-19 against those without COVID-19. Methods We systematically analysed 348 STEMI cases presenting to the PPCI programme in London during the peak of the pandemic (1 March to 30 April 2020) and compared with 440 cases from the same period in 2019. Outcomes of interest included ambulance response times, timeliness of revascularisation, angiographic and procedural characteristics, and in-hospital clinical outcomes Results There was a 21% reduction in STEMI admissions and longer ambulance response times (87 (62–118) min in 2020 vs 75 (57–95) min in 2019, p<0.001), but that this was not associated with a delays in achieving revascularisation once in hospital (48 (34–65) min in 2020 vs 48 (35–70) min in 2019, p=0.35) or increased mortality (10.9% (38) in 2020 vs 8.6% (38) in 2019, p=0.28). 46 patients with active COVID-19 were more thrombotic and more likely to have intensive care unit admissions (32.6% (15) vs 9.3% (28), OR 5.74 (95%CI 2.24 to 9.89), p<0.001). They also had increased length of stay (4 (3–9) days vs 3 (2–4) days, p<0.001) and a higher mortality (21.7% (10) vs 9.3% (28), OR 2.72 (95% CI 1.25 to 5.82), p=0.012) compared with patients having PPCI without COVID-19. Conclusion These findings suggest that PPCI pathways can be maintained during unprecedented healthcare emergencies but confirms the high mortality of STEMI in the context of concomitant COVID-19 infection characterised by a heightened state of thrombogenicity.

The purpose of this document is to update the existing joint British Societies recommendations on multidisciplinary meetings (MDMs) published in 2015 to reflect changes in practice. We aim to provide guidance on the structure and function of MDMs which should be taking place in every cardiac surgical centre. Out of scope are MDMs that do not require the routine presence of a cardiac surgeon such as electrophysiology MDMs and those which are not provided in every centre, such as complex aortic surgery.
