Background: The coronary sinus reducer (CSR) is proposed to reduce angina in patients with stable coronary artery disease by improving myocardial perfusion. We aimed to measure its efficacy, compared with placebo, on myocardial ischaemia reduction and symptom improvement.

Methods: ORBITA-COSMIC was a double-blind, randomised, placebo-controlled trial conducted at six UK hospitals.

Background: For women undergoing drug-eluting stent (DES) implantation, the individual and combined impact of chronic kidney disease (CKD) and diabetes mellitus (DM) on outcomes is uncertain.

Aims: We sought to assess the impact of CKD and DM on prognosis in women after DES implantation.

Methods: We pooled patient-level data on women from 26 randomised controlled trials comparing stent types.

Background: Coronary access after transcatheter aortic valve implantation (TAVI) with supra-annular self-expandable valves may be challenging or un-feasible. There is little data concerning coronary access following transcatheter aortic valve-in-valve implantation (ViV-TAVI) for degenerated surgical bioprosthesis.

Aims: To evaluate the feasibility and challenge of coronary access after ViV-TAVI with the supra-annular self-expandable ACURATE neo valve.

Transfemoral transcatheter aortic valve replacement is an effective treatment for severe aortic stenosis with a high rate of procedural success with the current devices. However, anatomic factors and device limitations may increase technical difficulty. We describe the balloon nudge technique, a novel technique that improves coaxial alignment while crossing the aortic valve.

We review the cardiac presentations, in-hospital outcomes and development of cardiovascular complications in the initial cohort of SARS-CoV-2 positive patients at Imperial College Healthcare National Health Service Trust, UK.

Methods: We retrospectively analysed 498 COVID-19 positive adult admissions to our institute from 7 March to 7 April 2020.

Objectives: The aims were to compare the frequency with which male and female cardiologists experience sexism and to explore the types of sexism experienced in cardiology.

Methods: A validated questionnaire measuring experiences of sexism and sexual harassment was distributed online to 890 UK consultant cardiologists between March and May 2018. χ tests and pairwise comparisons with a Bonferroni correction for multiple analyses compared the experiences of male and female cardiologists.

Aims: To assess left ventricular (LV) function before and after transcatheter aortic valve implantation (TAVI) using conventional echocardiographic parameters and global longitudinal LV strain (GLS) and compare outcomes between Edwards S3 and Evolut R valves.

Methods And Results: Data were collected for consecutive patients undergoing TAVI at Hammersmith hospital between 2015 and 2018. Of the 303 patients, those with coronary artery disease and atrial fibrillation were excluded leading to a total of 85 patients, which constituted our study group.

Objective: To evaluate the incidence, predictors and outcomes of female patients with patient-prosthesis mismatch (PPM) following transcatheter aortic valve intervention (TAVI) for severe aortic stenosis (AS).

Background: Female AS TAVI recipients have a significantly lower mortality than surgical aortic valve replacement (SAVR) recipients, which could be attributed to the potentially lower PPM rates. TAVI has been associated with lower rates of PPM compared to SAVR.

Background: Female subjects constitute half of all transcatheter aortic valve implantation (TAVI) candidates, but the association between important comorbidities such as diabetes mellitus (DM) and clinical outcomes after TAVI remains unclear in this group.

Method: WIN-TAVI is a real-world international registry of exclusively female subjects undergoing TAVI. The study population was stratified into those with (DM) and those without DM (NDM).

Article Synopsis
  • Transcatheter aortic valve replacement (TAVR) is a recognized treatment for severe aortic stenosis and has recently been applied to treat failures of bioprosthetic surgical aortic valves (sAVR) through a technique known as valve-in-valve TAVR (ViV-TAVR).
  • Though data on ViV-TAVR primarily come from observational studies, initial findings suggest it offers similar outcomes to re-do sAVR in high-risk patients.
  • The case presented in this text highlights a rare situation of TAVR failure in a patient who had prior sAVR, necessitating an innovative procedure called valve-in-valve-in-valve TAVR (ViViV-TAVR).

Background: The rise in an ageing population has resulted in an increase in the prevalence of aortic stenosis. With the advent and rapid expansion in the use of transcatheter aortic valve replacements (TAVRs), patients with severe aortic stenosis, traditionally thought too high risk for surgical intervention, are now being treated with generally favourable results. Frailty is an important factor in determining outcome after a TAVR, and an assessment of frailty is fundamental in the identification of appropriate patients to treat.

Objectives: The aim of this study was to investigate whether therapeutic intravascular ultrasound pulmonary artery denervation (PDN) is safe and reduces pulmonary vascular resistance (PVR) in patients with pulmonary arterial hypertension (PAH) on a minimum of dual oral therapy.

Background: Early studies have suggested that PDN can reduce PVR in patients with PAH.

Methods: TROPHY1 (Treatment of Pulmonary Hypertension 1) was a multicenter, international, open-label trial undertaken at 8 specialist centers.

Background: The prevalence of both chronic kidney disease (CKD) and aortic stenosis (AS) increase with age. Although baseline CKD is frequent in patients undergoing transcatheter aortic valve replacement (TAVR), its significance among women is largely unknown.

Methods: Women's INternational Transcatheter Aortic Valve Implantation (WIN-TAVI) is a multinational, prospective registry of women undergoing TAVR for severe AS.

We sought to analyze outcomes of women receiving balloon-expandable valves (BEV) or self-expanding valves (SEV) in contemporary transcatheter aortic valve implantation (TAVI). WIN TAVI (Women's INternational Transcatheter Aortic Valve Implantation) is the first all-female TAVI registry to study the safety and performance of TAVI in women. We compared women treated with BEV (n = 408, 46.

Background: Data examining the impact of diabetes mellitus (DM) on ischemic risk after percutaneous coronary intervention in women are limited as most clinical trial participants are male. We evaluated (1) the impact of DM on ischemic outcomes in women undergoing drug-eluting stent (DES) implantation and (2) whether the outcomes of new- versus early-generation DES vary by DM status.

Methods And Results: We pooled patient-level data of 10 448 women undergoing percutaneous coronary intervention with DES from 26 randomized trials.

Background: Several clinical and procedural factors determine outcomes after transcatheter aortic valve replacement (TAVR), but data are scarce on the impact of post-TAVR discharge disposition on long-term outcomes. We sought to analyse whether discharge location after TAVR is associated with 1-year outcomes in women undergoing contemporary TAVR.

Methods: The Women's INternational Transcatheter Aortic Valve Implantation (WIN-TAVI) registry is the first all-female TAVR registry to study the safety and performance of contemporary TAVR in women (n = 1019).

Aim: Severe aortic stenosis frequently involves the development of left ventricular hypertrophy (LVH) creating a dichotomous haemodynamic state within the coronary circulation. Whilst the increased force of ventricular contraction enhances its resultant relaxation and thus increases the distal diastolic coronary "suction" force, the presence of LVH has a potentially opposing effect on ventricular-coronary interplay. The aim of this study was to use non-invasive coronary wave intensity analysis (WIA) to separate and measure the sequential effects of outflow tract obstruction relief and then LVH regression following intervention for aortic stenosis.

Several expert documents on sex-based differences in interventional outcomes are now available, however this is the first position paper from the EAPCI Women Committee discussing the potential influence of sex in the percutaneous treatment of coronary and structural heart disease. Despite the misconception that coronary artery disease is a 'man's disease', contemporary data shows a growing incidence in women. However, women are under-represented in randomised coronary clinical trials (~25%).
