The emphasis in ischaemic heart disease (IHD) diagnosis has historically been directed towards the identification of epicardial coronary stenosis by selective coronary angiography, and its management by percutaneous coronary intervention (PCI) or coronary bypass graft surgery. Over the past two decades, the application of coronary physiology techniques to identify the haemodynamic severity of…

The original studies of coronary balloon angioplasty performed by Andreas Gruentzig attempted to employ physiological guidance by measuring trans-stenotic gradients with over-the-wire angioplasty catheters.1 However, these catheters were of such large calibre that they contributed to the stenosis being assessed and in addition, measurements were made at rest as the importance of assessing…

The optimal assessment and management of patients presenting with recent onset chest pain is achieved by acquiring information about the coronary anatomy and physiology, enabling decisions to be made based upon evidence of ischaemia at a patient-level and at lesion-level. There are robust data indicating that the visual assessment of stenosis severity alone does not provide enough information…

Terminology
When the first-in-human implantation of a bioresorbable device into the coronary artery was reported in 2007, the term ‘fully bioabsorbable stent’ was used.1 Later, in 2011, Onuma and colleagues explained that the term ‘bioresorbable’ provides a more precise description of the complete cleavage of macromolecules to small molecules with total elimination and the term ‘scaffold’ was…

The foramen ovale is an integral component of the fetal circulation, responsible for facilitating the flow of placental pre-xygenated venous blood from the right atrium to the left, thereby circumventing the quiescent developing lungs. Physiological closure is usually achieved after birth when pulmonary vascular resistance and right heart pressures reduce, resulting in the left atrial pressure…
