Multicenter StudyImproving Guideline Compliance in Australia With a National Percutaneous Coronary Intervention Outcomes Registry.
Secondary prevention strategies after percutaneous coronary intervention (PCI) include statins and dual anti-platelet therapy, however there are significant gaps between guidelines and practice. Contemporary PCI practice requires comprehensive data collection to allow dynamic auditing and benchmarking of key performance and safety indices. Genesis HeartCare is Australia's largest collaborative venture of cardiologists, practising at over 40 public and private hospitals. We hypothesised that measurement and local reporting of data would improve patient outcomes through improving compliance with guideline therapies. ⋯ This large-scale collaboration provides a platform for the development of quality improvement initiatives. Establishment of this clinical quality registry improved patient care by identifying and monitoring gaps in delivery of appropriate therapies, driving key practice change.

Comparative StudyComparison of Safety and Efficacy of Unfractionated Heparin Versus Bivalirudin in Patients Undergoing Percutaneous Coronary Intervention.
Anti-platelet and anti-coagulant adjunctive therapies are associated with a clinically significant increased risk of major bleeding. We retrospectively assessed in-hospital major adverse clinical events (MACE) and major bleeding in patients undergoing percutaneous coronary intervention (PCI) who received either unfractionated heparin (UFH) or bivalirudin. ⋯ Unfractionated heparin compared with bivalirudin was not associated with a higher incidence of in-hospital MACE or major bleeding in a cohort with overall high rates of transfemoral access, despite significantly higher use of GPIIb/IIIa antagonists in the UFH group.

Comparative Study Observational StudyDifferences in Presentation, Management and Outcomes in Women and Men Presenting to an Emergency Department With Possible Cardiac Chest Pain.
Research suggests that female patients with acute coronary syndrome (ACS) experience delays in emergency department (ED) management and are less likely to receive guideline-based treatments and referrals for follow-up testing. Women are often found to have poorer clinical outcomes in comparison to men. This study aimed to assess current sex differences in the presentation, management and outcomes of patients with undifferentiated chest pain presenting to a tertiary ED. ⋯ Minimal sex differences were observed in the contemporary emergency management of patients presenting with suspected ACS. Thirty-day outcomes were similarly low in men and women despite lower rates of coronary angiography and revascularisation in women. Further research is required to replicate these results in different hospital systems and cultural settings.

Case ReportsConventional Surgery for Early and Late Symptomatic Mitral Valve Stenosis After MitraClip® Intervention: An Institutional Experience With Four Consecutive Patients.
Surgical mitral valve repair is the gold standard for treatment of mitral regurgitation. Recently, the transcatheter treatment of mitral regurgitation with the MitraClip® device (Abbot Vascular Structural Heart, Menlo Park, CA) has demonstrated promising results in treating patients not amenable for surgical correction of mitral valve regurgitation. Most patients reported in the literature requiring surgical bailout after MitraClip treatment presented with residual or recurrent mitral valve regurgitation. Mitral valve stenosis after MitraClip treatment has been rarely reported. ⋯ Placement of multiple clip devices may lead to slightly elevated transmitral gradients. This may not necessarily interpret into symptomatic mitral stenosis. However, in some cases this is possible. Caution should be exercised at this phase of the learning curve of the percutaneous MC treatment, especially in use of multiple MC devices.

Single-Centre Experience of Off-Pump Multi-Vessel Coronary Artery Bypass Grafting Using Proximal Suture Device.
To investigate the results of off-pump coronary artery grafting (OPCAB) with the proximal suture device (PSD) regarding postoperative stroke and graft patency. ⋯ Off-pump coronary artery grafting using the PSD was a safe and effective procedure. It led to lower incidences of postoperative stroke and excellent rates of graft patency and complete revascularisation compared with conventional CABG.
