Antegrade Perfusion for Mini-Thoracotomy Mitral Valve Surgery in Patients with Atherosclerotic Burden
The relationship between retrograde arterial perfusion and stroke in patients with peripheral vascular disease has been widely documented. Antegrade arterial perfusion has been favoured as an alternative approach in less invasive mitral valve (MV) operations. We aimed to analyse our experience in patients with peripheral arterial disease undergoing MV surgery through a right mini-thoracotomy adopting antegrade arterial perfusion.

189 Unexpected, Wanted and Kept: Management of a Pregnancy With Severe LV Dysfunction, Re-Do Mechanical Mitral Valve and Recurrent Arrythmias
We present the multidisciplinary management of a 31YO women with an unexpected pregnancy. Her background included congenital ASD and VSD, surgical repair of PDA and severe aortic coarctation at 2 weeks. Resection of sub-aortic membrane and repair of anterior mitral valve prolapse at 7 years. First mitral valve replacement (MVR) at 16 years of age (tissue valve), second MVR (mechanical) at 27 after presenting with a stroke due to valve thrombosis. LVEF 25% and severely dilated.

424 Underestimation of Left Ventricular (LV) Dilatation by Linear Dimensions in Comparison to Volumetric Assessment in Chronic Severe Aortic Regurgitation (AR) – Time to Update the Management Guidelines?
Chronic severe AR (CSAR) results in compensatory LV dilatation to maintain forward stroke volume. “Severe” dilatation (LV end-diastolic dimension (LVEDD)) ≥80mm is associated with sudden cardiac death and poorer postoperative outcomes. European Society of Cardiology guidelines recommend valve surgery (Class IIa) in asymptomatic patients with LVEDD>70mm and LV ejection fraction (LVEF)>50%. LVEDD underestimates LV dilatation due to geometrical limitations in comparison to volumetric measurements (Indexed LV end-diastolic volume (iLVEDV)), however thresholds for intervention remain unchanged.

Dual Versus Single Antiplatelet Therapy in Patients Undergoing Transcatheter Aortic Valve Replacement: A Systematic Review and Meta-analysis
Although dual antiplatelet therapy (DAPT) with clopidogrel and aspirin is a widely accepted strategy in patients undergoing transcatheter aortic valve replacement (TAVR), this approach is not evidence based. We therefore sought to systematically review the current evidence for this practice in terms of 30-day outcome looking at stroke, MI, bleeding, and death.

Cardiac Surgery in Indigenous Australians: Early Onset Cardiac Disease with follow-up Challenges
Conclusions: The mean age of 52 years at which Indigenous patients have cardiac surgery is significantly low compared to non-Indigenous patients. Indigenous patients have multiple risk factors for cardiac disease and with a large number requiring emergency surgery. Although surgical outcome in the short term is favourable, a large number of patients are lost to follow-up. The use of mechanical valve and warfarin should be individualised. Strategic post-operative follow-up mechanisms are needed to address these issues.

Antiplatelet versus Antithrombotic Therapy After Bioprosthetic Aortic Valve Replacement
Background: Aortic valve replacement with bioprosthesis is one of the commonest operations in cardiac surgery. Despite its frequency and a large number of patients post biological AVR there is no agreement on the best postoperative management of these patients in terms of reduction of cardiovascular death and prevention of thromboembolic complications short- and long-term (stroke, myocardial infarction, peripheral vascular thromboembolic events) maintaining low incidence of haemorrhagic complications. The main question is whether antiplatelet or antithrombotic therapy is more beneficial for the patients.

Surgical Aortic Valve Replacement in Very Elderly Patients Aged 80 Years and Over: Evaluation of Early Clinical Outcomes
Background: An increasing number of very elderly patients aged ≥80 years will require aortic valve replacement (AVR) for severe aortic stenosis (AS). Many are classified as high-risk surgical candidates. Transcatheter aortic valve implantation (TAVI) has been proposed as an alternative to surgical AVR (SAVR) for high-risk patients. We evaluated early clinical outcomes of very elderly patients undergoing SAVR to optimise TAVI candidate selection.Methods: We conducted a retrospective case review of 132 consecutive patients aged ≥80 years undergoing isolated SAVR (49 patients) or combined SAVR/CABG (83 patients) during Fe...
