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.

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.

Early outcome of transcatheter aortic-valve implantation in high risk patients: The Auckland experience from 2011 to 2014

Up to one third of patients may be denied surgical aortic valve replacement (AVR) because of co-morbid conditions. Transcatheter aortic-valve implantation (TAVI) is an alternative to aortic valve replacement in high risk patients with symptomatic severe aortic stenosis.
