BACKGROUND: Whilst home-based telerehabilitation has been shown non-inferior to traditional centre-based rehabilitation in patients with chronic heart failure, its economic sustainability remains unknown. This study aimed to investigate the cost-utility of a home-based telerehabilitation program. METHODS: A comparative, trial-based, incremental cost-utility analysis was conducted from a health care provider's perspective. We collected data as part of a multi-centre, two-arm, non-inferiority, randomised controlled trial with 6 months follow-up...

BACKGROUND: Aortic stenosis (AS) is a common valvular abnormality and transcatheter aortic valve implantation (TAVI) is being increasingly used to treat patients considered too high risk for conventional surgery. We aimed to assess the prevalence of comorbid conditions in patients undergoing TAVI using the Charlson Comorbidity Index (CCI) and to assess their impact on clinical and procedural outcomes. METHODS: We analysed 158 patients who underwent a TAVI at our institution between June 2009 and September 2015 to define their co-morbid burden as measured with CCI, and study its impact on procedural characteristics and mortality at 30 days...

BACKGROUND: The Cox-Maze IV procedure is a proven surgical treatment for atrial fibrillation (AF). Previous studies on the procedure and its effect on left atrial mechanical function have yielded mixed results. METHODS: Sixty-four patients underwent Cox-Maze IV at St Vincent's Hospital, Melbourne between March 2010 and May 2016. Baseline characteristics were collected and outcomes assessed including rhythm analysis. Preoperative and postoperative transthoracic echocardiograms were reviewed...

BACKGROUND: Re-admission is an important source of patient dissatisfaction and increased hospital costs. A simple calculator to determine the probability of re-admission may help guide patient dismissal planning. METHODS: Using the national readmissions database (NRD), we identified admissions for isolated primary coronary artery bypass (CABG) and stratified them according to 30-day readmission. Including pre, intra and postoperative variables, we prepared a logistic regression model to determine the probability for re-admission...

BACKGROUND: Right ventricular apical (RVA) pacing is related to adverse left ventricular (LV) remodelling. This study assessed changes in global longitudinal strain (GLS) after permanent RVA pacing, and investigated whether GLS at one month can predict later LV ejection fraction (LVEF) decline. METHODS: The study enrolled 68 patients with normal LVEF (≥50%) who underwent dual chamber pacemaker implantation for third-degree atrioventricular block. Global strains and LVEF were assessed using three-dimensional (3D) speckle tracking strain echocardiography (STE)...

BACKGROUND: Enhanced recovery programs within cardiothoracic surgery are a well described benefit to patient postoperative outcomes. We describe our Australasian unit's experience of a day zero discharge enhanced recovery unit from the intensive care department. METHODS: A retrospective study was conducted on a prospectively maintained database at Waikato Cardiothoracic Unit from September 2014 till October 2017 with 1,739 patients undergoing cardiac surgery. Twenty-two (22) patients were excluded as deaths either intraoperative or in the intensive care unit (ICU) and therefore never discharged...

BACKGROUND: Catheter ablation (CA) is highly efficacious for symptomatic atrial fibrillation (AF) but data predominantly comes from patients with preserved ventricular function. We performed an updated systematic review and meta-analysis of randomised controlled trials (RCT) comparing CA versus medical therapy for AF associated with heart failure (HF). METHODS: Medline, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for RCTs reporting clinical outcomes of CA versus medical therapy for AF in HF patients with ≥6 months' follow-up (atrioventricular-node ablation/device therapy studies excluded)...

BACKGROUND: Mini-sternotomy has been proven superior to full sternotomy in aortic valve replacement by providing better perioperative outcomes. We investigated whether such technique provides better outcomes in patients undergoing aortic root surgery. METHODS: A comprehensive electronic literature search was undertaken among the four major databases (PubMed, Ovid, Scopus and EMBASE) to identify all published studies up to June 2018. The search terms used related to mini-sternotomy versus full sternotomy, aortic root, valve sparing, Bentall procedure...

BACKGROUND: Prolonged screening for the presence of atrial fibrillation (AF) is recommended after cryptogenic stroke (CS) and different electrocardiographic markers of atrial cardiopathy have been proposed as tools to identify patients at high-risk for AF. AIM: The aim of this study was to evaluate the relationship between different electrocardiographic parameters and in-hospital AF occurrence after acute CS. METHOD: In total, 222 patients with CS underwent 12-lead resting electrocardiogram (ECG) at admission and 7-day in-hospital ECG monitoring in order to evaluate the possible occurrence of silent AF...

Fasting blood glucose, postprandial blood glucose and glycated haemoglobin are considered three important indicators for diabetes treatment. There is increasing evidence that glucose variability has more detrimental effects on the coronary arteries than does chronic sustained hyperglycaemia. This overview summarises recent findings in the field of glucose variability and its possible relationship with coronary artery disease. Glucose variability may be a marker of increased progression of coronary disease and plaque vulnerability...

BACKGROUND: Isolated, fusiform aneurysms, exclusively affecting the tubular portion of the ascending aorta, are rare. Surgical treatment aims to change their natural course, reducing individual and cumulative risks of rupture, dissection and death. Open tubular graft replacement still remains the procedure of choice, despite significant risks. In permanent pursuit for optimal, alternative surgical strategy in high-risk patients, less invasive and off-pump plicating ascending aortoplasty with modified external Dacron graft wrapping seems to be a reliable choice...

BACKGROUND: Adult congenital heart disease (ACHD) is a relatively new subspecialty in the cardiology field. The prevalence of ACHD is estimated at ∼ 3,000 per million adult population. The ACHD patient group is estimated to grow at ∼ 5% per year and in the next decade it is forecast that 1 in 150 young adults will carry some form of ACHD diagnosis. These estimates translate to ∼ 72,000 ACHD patients in Australia and ∼ 14,000 in New Zealand, although no current numbers are available...

Arrhythmogenic cardiomyopathy (ACM) is now commonly used to describe any form of non-hypertrophic, progressive cardiomyopathy characterised by fibrofatty infiltration of the ventricular myocardium. Right ventricular (RV) involvement refers to the classical arrhythmogenic right ventricular cardiomyopathy, but left ventricular, or bi-ventricular involvement are now recognised. ACM is mostly hereditary and associated with mutations in genes encoding proteins of the intercalated disc. ACM classically manifests as ventricular arrhythmias, and sudden death may be the first presentation of the disease...

Non-ischaemic cardiomyopathy (NICM) encompasses a heterogeneous group of disorders that includes genetic, idiopathic, post viral and inflammatory cardiomyopathies. NICM is associated with an increased risk of ventricular arrhythmias (VAs), namely in the form of ventricular tachycardia (VT). Although implanted cardiac defibrillators (ICD) may prevent sudden death from VA, NICM patients may suffer from recurrent symptoms and ICD therapies, and anti-arrhythmic drug side effects. Catheter ablation is highly efficacious in NICM, however poses unique challenges when compared to post myocardial infarction substrates...
