BACKGROUND: Non-obstructive coronary artery disease (CAD) on coronary angiography after myocardial infarction (MI) is associated with a lower risk of adverse outcomes, but the prognosis may not be benign. Our aim was to assess outcomes in MI with and without obstructive CAD, and in an age and sex matched comparison cohort without known cardiovascular disease. METHODS: We performed a single centre analysis of consecutive patients undergoing coronary angiography for MI between 2007 and 2012...

Transcatheter aortic valve replacement (TAVR) is traditionally performed under cardiac imaging guidance. In the early TAVR experience, intra-procedural transoesophageal echocardiography (TOE) is recommended to guide device deployment, in the context of general anaesthesia (GA). Intra-procedural TOE imaging is particularly useful during TAVR deployment as a contrast-saving strategy for patients with renal impairment. Evidence has emerged recently demonstrating that in selected patients, transthoracic echocardiography (TTE) can be used to provide intra-procedural guidance for TAVR...

BACKGROUND: The clinical impact of pulmonary capillary wedge pressure (PCWP) on long-term mortality among patients with pulmonary arterial hypertension (PAH) has been incompletely reported, particularly in relation to concomitant treprostinil administration. The goal of this study was to assess the impact of PCWP on long-term mortality in PAH patients treated with parenteral treprostinil. METHODS: We studied a cohort of 743 patients with PAH treated with parenteral treprostinil therapy...

BACKGROUND: To identify the predictors of left ventricular functional recovery (LVFR) and its impacts on clinical outcomes in acute heart failure (AHF) patients with newly diagnosed dilated cardiomyopathy (DCM). METHODS: A total of 175 consecutive patients with newly diagnosed DCM and AHF were divided into two groups according to LVFR on FU echocardiography; the recovered group (n=54, 54.3±18.5years, 31 males) vs. the non-recovered group (n=121, 60.5±15.1years, 79 males)...

BACKGROUND: Surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI) are increasingly performed in octogenarian patients with severe aortic stenosis (AS), including those with high surgical risk. Postoperative delirium (PD) is a common and serious complication in older patients, characterised by reduced awareness, change in consciousness, disturbance in logical thinking and hallucinations. METHODS: To explore how octogenarian patients experienced PD, a qualitative study was conducted including five women and five men between 81 and 88 years...

BACKGROUND: Data on the use of GPIIb-IIIa receptor inhibitors (GPI) in acute coronary syndrome (ACS) patients presenting with cardiogenic shock and/or after cardiopulmonary resuscitation is sparse. The aim of the study was to establish the possible influence of the adjunctive use of GPI on 30-day and 1-year mortality in these high-risk patients. METHODS: Acute coronary syndrome patients (261), who presented with cardiogenic shock and/or were cardiopulmonary resuscitated on admission, were analysed...

REVIEW
S Subedi, Z Jennings, S C-A Chen
Blood-culture negative endocarditis (BCNE) accounts for up to 35% of all cases of infective endocarditis (IE) and is a serious life-threatening condition with considerable morbidity and mortality. Rapid detection and identification of the causative pathogen is essential for timely, directed therapy. Blood-culture negative endocarditis presents a diagnostic and therapeutic challenge. Causes of BCNE are varied including: treatment with antibiotic agents prior to blood culture collection; sub-optimal specimen collection; and/or infection due to fastidious (eg...

BACKGROUND: Short-term mortality prediction models have an important role in current cardiac surgical practice. There has been much less attention paid to prediction of long-term outcomes which are probably an equal marker both of surgeon performance and appropriateness of surgical treatment. The aim of this study was to assess the performance of the New York State Cardiac Surgery Reporting System (NYSCSRS) risk model and the Northern New England Cardiovascular Disease Study Group (NNECDSG) risk model on the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) patient database...

Whilst the worldwide uptake of transcatheter aortic valve implantation (TAVI) over the last 10 years has been dramatic, iliac tortuosity remains a potential barrier to the most commonly chosen access route via the femoral artery. We describe the challenges posed by severe iliac tortuosity during transfemoral TAVI and contrast a difficult procedure - at the limit of the capability of current device delivery technology - with a straightforward implantation. The use of pre-procedural multi-detector computed tomography to assess the vasculature and a bilateral stiff wire technique for managing iliofemoral tortuosity are discussed...

REVIEW
A V Gaddi, P Galuppo, J Yang
BACKGROUND: Creatine phosphate (CrP) plays a fundamental physiological role by providing chemical energy for cell viability and activity, especially in muscle tissue. Numerous pathological conditions, caused by acute or chronic ischaemic situations, are related to its deficiency. For these reasons, it has been used as a cardioprotective agent in heart surgery and medical cardiology for many years. OBJECTIVE: This article gives a brief overview of the main characteristics of exogenous CrP...

BACKGROUND: Lactate has been recognised as a prognostic factor in several critical conditions. Veno-Venous Extracorporeal Membrane Oxygenation (VV-ECMO) is a well-established therapy in patients with Acute Respiratory Disease Syndrome (ARDS) unresponsive to conventional therapy and echocardiography pre ECMO initiation has been recently reported to help in risk stratifying these patients. METHODS: We assessed whether the detection of hyperlactataemia could be associated with the presence of left ventricle (LV) or right ventricle (RV) dysfunction in 121 consecutive patients with refractory ARDS...

BACKGROUND: Zinc is one of the most important microelements in the body and zinc homeostasis plays a critical role in maintaining cellular structure and function. Zinc dyshomeostasis can lead to many diseases, such as cardiovascular disease. Our aim was to investigate whether there is a relationship between zinc and cardiac markers, and the risk of acute myocardial infarction (AMI) by zinc quartiles. METHODS: We enrolled a total of 529 patients and measured their serum zinc levels and cardiac markers...

BACKGROUND: The association between bicuspid aortic valve (BAV) and hypertrophic cardiomyopathy (HCM) has been reported but its true prevalence is unknown. This study investigated the prevalence and clinical impact of coexistent BAV in a large referral HCM population. METHODS: Retrospective analysis of 3765 echocardiograms between 2004 and 2014 in 2640 consecutive patients with HCM was performed to assess for BAV. Patients with coexistent conditions were studied...

BACKGROUND: The use of aspirin versus warfarin for treatment of patients after a Fontan procedure remains contentious. Current preference-based models of treatment across Australia and New Zealand show variation in care that is unlikely to reflect patient differences and/or clinical risk. METHODS: We combine data from the Australian and New Zealand Fontan Registry and a home INR (International Normalised Ratio) monitoring program (HINRMP) from the Royal Children's Hospital (RCH) Melbourne, to estimate the cost difference for Fontan recipients receiving aspirin versus warfarin for 2015...

BACKGROUND: Although smoking is known to be associated with cardiovascular diseases, the number of large-scale cohort studies on the association between smoking and atrial fibrillation (AF) is limited and the results obtained are also inconsistent, and even fewer studies have addressed the difference between the male and female genders. The present study was intended to clarify and quantify the association between smoking and the risk of AF in men versus women. METHODS: Using AF- and smoking-related keywords, a comprehensive literature search on PubMed, EMbase and Web of Science was conducted with a time limit until December 2016, which was followed by manual screening, quality assessment and data extraction...

A 28-year-old male was admitted to hospital with an acute ST-elevation myocardial infarction. This was in the context of recreational abuse of nitrous oxide. The prevalence of nitrous oxide use in Australia has not been formally quantified, however it is the second most commonly used recreational drug in the United Kingdom. Nitrous oxide has previously been shown to increase serum homocysteine levels. This patient was discovered to have an elevated homocysteine level at baseline, which was further increased after nitrous oxide consumption...
