Incidence and Predictors of Early and Late Radial Artery Occlusion after Percutaneous Coronary Intervention and Coronary Angiography: A Systematic Review and Meta-Analysis.

Trans-radial access for coronary angiography and percutaneous coronary intervention (PCI) has gained popularity due to its advantages over the traditional transfemoral approach. However, radial artery occlusion (RAO) remains a common complication following trans-radial procedures. This study aimed to investigate the incidence of early and late RAO along with their risk factors.

Bi-National Outcomes of Redo Surgical Aortic Valve Replacement in the Era of Valve-in-Valve Transcatheter Aortic Valve.

Background: Implantation of bioprosthetic valves is more common as the population ages and there is a shift towards implanting bioprosthetic aortic valves in an increasingly younger surgical population. Bioprosthetic heart valve insertion, however, carries the long-term risk of valve failure through structural valve degeneration. Re-operative surgical aortic valve replacement has historically been the only definitive management option for patients with prosthetic valve dysfunction, however, data on the short- and long-term outcomes following re-operative surgery in Australia and New Zealand is limited.

2023 Cardiac Society of Australia and New Zealand Expert Position Statement on Catheter and Surgical Ablation for Atrial Fibrillation.

Catheter ablation for atrial fibrillation (AF) has increased exponentially in many developed countries, including Australia and New Zealand. This Expert Position Statement on Catheter and Surgical Ablation for Atrial Fibrillation from the Cardiac Society of Australia and New Zealand (CSANZ) recognises healthcare factors, expertise and expenditure relevant to the Australian and New Zealand healthcare environments including considerations of potential implications for First Nations Peoples. The statement is cognisant of international advice but tailored to local conditions and populations, and is intended to be used by electrophysiologists, cardiologists and general physicians across all disciplines caring for patients with AF.

Characteristics and Outcomes of a Single-Centre Cohort of Adult Congenital Heart Disease Patients Referred for Heart Transplant.

Background: Adult congenital heart disease (ACHD) services increasingly encounter heart failure (HF) in the ageing ACHD population. Optimal timing of referral for heart transplant (HTx) evaluation in this heterogeneous population is complex and ill-defined. We aim to outline the characteristics and outcomes of ACHD patients referred for HTx from a large Australian ACHD centre.

HeartMate 3 implantation with an emphasis on the biventricular configuration.

Objectives: Right ventricular failure following implantation of a durable left ventricular assist device (LVAD) is a major driver of mortality. Reported survival following biventricular (BiVAD) or total artificial heart (TAH) implantation remains substantially inferior to LVAD alone. We report our outcomes with LVAD and BiVAD HeartMate 3 (HM3).

Impact of postoperative hyperlactatemia in orthotopic heart transplantation.

Background: Hyperlactatemia (HL) is a common phenomenon after cardiac surgery which is related to tissue hypoperfusion and hypoxia and associated with poor outcomes. It is also often seen in the postoperative period after orthotopic heart transplantation (OHTx), but the association between HL and outcomes after OHTx is not well known. We evaluated the incidence and outcome of HL after OHTx.

Use of Sutureless Valve in Aortic Root Enlargement.

Aim: The small aortic annulus is a surgical challenge in patients undergoing aortic valve replacement which may lead to patient prosthesis mismatch. Management options include aortic root enlargement, aortic root replacement, and the use of sutureless valves. In this case series, we report our results with aortic root enlargement, sutureless valve implantation, and benchtop modelling of the radial forces exerted.

Hypothermic oxygenated perfusion (HOPE) safely and effectively extends acceptable donor heart preservation times: Results of the Australian and New Zealand trial.

Background: Cold static storage preservation of donor hearts for periods longer than 4 hours increases the risk of primary graft dysfunction (PGD). The aim of the study was to determine if hypothermic oxygenated perfusion (HOPE) could safely prolong the preservation time of donor hearts.

Methods: We conducted a nonrandomized, single arm, multicenter investigation of the effect of HOPE using the XVIVO Heart Preservation System on donor hearts with a projected preservation time of 6 to 8 hours on 30-day recipient survival and allograft function post-transplant.

Left main coronary artery to pulmonary artery fistula presenting as angina and ventricular tachycardia - A case report and literature review.

Coronary artery fistulae are an uncommon abnormality of the coronary arteries, but when hemodynamically significant can present as angina, dyspnea, and arrhythmia as a rare cause of functional myocardial ischemia via 'coronary steal phenomenon'.

Flail chest injury-changing management and outcomes.

Purpose: The purpose of this study was to assess trends in management of flail chest injuries over time and to determine impact on patient outcomes.

Methods: A retrospective review of data from a prospectively collated database of all trauma patients admitted to a level 1 trauma service in Victoria was conducted. All trauma patients admitted to the hospital between July 2008 and June 2020 with an Abbreviated Injury Scale (AIS) code for flail chest injury were included.

Surgical stabilization of rib fractures versus nonoperative treatment in patients with multiple rib fractures following cardiopulmonary resuscitation: An international, retrospective matched case-control study.

Background: The presence of six or more rib fractures or a displaced rib fracture due to cardiopulmonary resuscitation (CPR) has been associated with longer hospital and intensive care unit (ICU) length of stay (LOS). Evidence on the effect of surgical stabilization of rib fractures (SSRF) following CPR is limited. This study aimed to evaluate outcomes after SSRF versus nonoperative management in patients with multiple rib fractures after CPR.

Spontaneous Coronary Artery Dissection in an Orthotopic Heart Transplant Recipient.

We present the case of acute myocardial infarction secondary to spontaneous coronary artery dissection in a patient 2 weeks post orthotopic heart transplantation. ().

Heart-Lung Transplantation: Technical Modifications to Simplify the Procedure.

Heart-lung transplantation is a mature therapy but has perioperative complications, such as phrenic nerve dysfunction and mediastinal bleeding. We report our technical modifications to simplify the procedure.

Extracorporeal Membrane Oxygenation as a Bridge to Surgical Repair of Postinfarct Ventricular Septal Defect.

Postinfarct ventricular septal defect (PIVSD) is associated with high mortality and the management of these patients has been a challenge with little improvement in outcomes. We commenced a protocol of veno-arterial extracorporeal membrane oxygenation (VA ECMO) for those patients who present in cardiogenic shock with the aim to improve end-organ function before definitive surgical repair to reduce postoperative mortality. This study reviewed the results of this strategy.
