Background: Transcatheter aortic valve implantation (TAVI) is most commonly performed via the femoral approach. Small caliber ilio-femoral arteries, severe calcification and tortuosity are often prohibitive reasons for TAVI via the femoral approach. Mid-aortic syndrome is a rare condition describing congenital or acquired coarctation of the abdominal aorta.

Background: Very little is known about long-term valve durability after transcatheter aortic valve replacement (TAVR).

Objectives: This study sought to evaluate the incidence of structural valve degeneration (SVD) 5 to 10 years post-procedure.

Methods: Demographic, procedural, and in-hospital outcome data on patients who underwent TAVR from 2007 to 2011 were obtained from the U.

Objectives: The objective was to define the characteristics of a real-world patient population treated with transcatheter aortic valve implantation (TAVI), regardless of technology or access route, and to evaluate their clinical outcome over the mid to long term.

Background: Although a substantial body of data exists in relation to early clinical outcomes after TAVI, there are few data on outcomes beyond 1 year in any notable number of patients.

Methods: The U.

Objective: High-risk patients with aortic stenosis are increasingly referred to specialist multidisciplinary teams (MDTs) for consideration of trans-catheter aortic valve implantation (TAVI). A subgroup of these cases is unsuitable for TAVI, and high-risk conventional aortic valve replacement (AVR) is undertaken. We have studied our outcomes in this cohort.

Background: Medical emergency teams (MET) have been shown to reduce in-hospital morbidity and mortality of surgical patients. The present study reviews the experience with the use of MET in the care of critically unwell surgical patients.

Methods: Data were prospectively collected on all patients in a general surgical unit of a tertiary referral centre meeting the criteria for activating a MET over a 6 month period.

Background: The use of intravenous glycoprotein IIb/IIIa-receptor antagonists has been shown to improve outcomes in patients undergoing percutaneous transluminal coronary angioplasty (PTCA). Tirofiban has shown benefit in a wide range of patients presenting with acute coronary syndromes. Although this agent has been used in patients undergoing percutaneous coronary intervention, a literature search identified no prospective data comparing tirofiban with placebo in patients undergoing planned intracoronary stent placement.
