Value of normal or mild coronary artery disease on angiography during workup of suspected angina pectoris

Coronary angiography is the standard technique for assessment of coronary artery disease (CAD). In many patients investigated with angiography, no or minimal CAD (<50% stenosis) is detected. It is uncertain how this “negative” result influences subsequent management and outcomes. We reviewed characteristics and outcomes in a contemporary cohort of patients with suspected angina pectoris and subsequently “negative” coronary angiography. T. Wang, T. Oh, C. Samaranayake, T.

Utility of pre-catheterisation high-sensitivity troponin T in patients without obstructive coronary artery disease

Myocardial infarction (MI) in patients subsequently shown to have no obvious, or trivial coronary artery disease (<50% stenosis) at angirography is seldom studied, but may be attributable to either a primary coronary event or, less commonly, type 2 MI. Recently developed, high-sensitivity troponin T (hs-TnT) assays have increased sensitivity for detection of minor degrees of myocardial necrosis, improving MI detection rate. We assessed the prognostic utility of pre-catheterisation hs-TnT in patients without angiographically significant coronary narrowing.

Features and outcomes of eosinophilic myocarditis: A single-centre case series

Eosinophilic myocarditis (EM) is a rare and potentially fatal entity characterised by inflammation with infiltrating eosinophils. Limited published data are available documenting presentation, management and prognosis. We report these data in a series of patients with EM treated at Auckland City Hospital.

Diagnosis of myocardial infarction after aortic valve replacement with high-sensitivity troponins

The Universal Definition for type 5 myocardial infarction (MI) applies to coronary artery bypass grafting (CABG), while perioperative MIs for other cardiac surgeries are rarely studied and not specifically defined. We assessed whether high-sensitivity troponin (hs-TnT), with or without concurrent ischaemic changes on electrocardiogram or echocardiogram, predicted mortality and morbidity after aortic valve replacement (AVR).

Fulminant myocarditis

Fulminant myocarditis is a rare condition with acute onset, rapid clinical deterioration and cardiogenic shock. We identified all adult patients with fulminant myocarditis referred to our institution over an eleven-year period and describe their initial management and clinical outcomes.

Total ambulatory care (TAC) for day-stay coronary angiography patients (Amsterdam protocol): A positive response with suggested enhancements

TAC seeks to deconstruct the traditional approach to diagnostic and interventional procedures: Long periods without food or drink, impersonal and unflattering attire, strong procedural sedation, restriction of movement and boredom. Radial artery access angiography allows us the opportunity to address these issues and provide patient-friendly care.

Reduced sedation in patients undergoing coronary angiography of total ambulatory management Online Only

Midazolam and fentanyl are routinely used for coronary angiography via a radial approach to reduce patient anxiety, pain and arterial spasm. This has implications for ambulation, time to discharge and work-flow efficiency. There is little evidence to support the routine use of “up-front” intravenous sedation and analgesia compared to “as required” and using local anaesthesia alone.

Introduction and evaluation of total ambulatory management of patients undergoing coronary angiography and intervention

Transradial coronary angiography and intervention has permitted the introduction of “demedicalised” total ambulatory care. We aimed to assess the feasibility and success of this strategy for day case coronary angiography/PCI at Auckland City Hospital.

Cost effectiveness of transcatheter aortic valve implantation (TAVI) for patients with severe symptomatic aortic stenosis in New Zealand

Patients with severe symptomatic aortic stenosis face a poor prognosis unless they undergo surgical aortic valve replacement (SAVR), yet many are at high risk due to co-morbidity, frailty or anatomical limitations. Clinically TAVI may be an appropriate alternative treatment; however, cost effectiveness requires careful consideration and will impact on funding. We aim to provide economic evidence and budget impact for the role for TAVI in the publicly funded New Zealand health care system.

Comparison of four contemporary risk scores for predicting mortality and morbidity after aortic valve replacement

Risk stratification for aortic valve replacement (AVR) is an important area given the increased demand for intervention and the introduction of transcatheter aortic valve implantation (TAVI). We compared the prognostic utility of EuroSCORE, EuroSCORE II, Society of Thoracic Surgeon’s (STS) Score and an Australasian model (Aus-AVR Score) for AVR.
