BACKGROUND Patients with "refractory angina" (RA) unsuitable for coronary revascularization experience high levels of hospitalization and poor health-related quality of life. Randomized trials have shown spinal cord stimulation (SCS) to be a promising treatment for chronic stable angina and RA; however, none has compared SCS with usual care (UC). The aim of(More)
OBJECTIVE The aim of the current study was to identify predictors of paraprosthetic aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) and examine its influence on short/medium-term mortality using the UK TAVI Registry. TAVI is an effective treatment for high-risk patients with severe symptomatic aortic stenosis (AS), but(More)
BACKGROUND The management and impact of concomitant coronary artery disease in patients referred for TAVI remains contentious. We describe the prevalence, clinical impact and management of coronary artery disease (CAD) in patients in the United Kingdom TAVI Registry. METHODS All-inclusive study of patients undergoing TAVI in the United Kingdom (excluding(More)
BACKGROUND As coronary perforation (CP) is a rare but serious complication of percutaneous coronary intervention (PCI) the current evidence base is limited to small series. Using a national PCI database, the incidence, predictors, and outcomes of CP as a complication of PCI were defined. METHODS AND RESULTS Data were prospectively collected and(More)

Coronary perforation (CP) is a rare but serious complication of percutaneous coronary intervention (PCI) with a previously estimated incidence of ≈0.4%. Although there are several published series of CP, the rarity of the complication has previously been limited to small numbers of cases derived from single-center experience. Most recently, we have(More)

Coronary perforation (CP) is a rare but serious complication of percutaneous coronary intervention (PCI) with an estimated incidence of ≈0.5%. Entry of arterial blood into the pericardial space can lead to rapid elevation of the pericardial pressure and rapid hemodynamic compromise. Historically, urgent surgical drainage was a standard treatment, but the(More)
BACKGROUND Coronary perforation (CP) during chronic total occlusion percutaneous coronary intervention for stable angina (CTO-PCI) is a rare but serious event. The evidence base is limited, and the long-term effects are unclear. Using a national PCI database, the incidence, predictors, and outcomes of CP during CTO-PCI were defined. METHODS AND RESULTS(More)
6. The primary outcome is described as prescription of ACEi and beta-blockers but in the results section of the abstract the figures relate to optimal prescription. Please confirm what the primary outcome was and give the result for the primary outcome. “Findings” is not sufficiently specific. Changes to the paper have been made to clarify the primary(More)
