One particular complexity of coronary artery is the natural tapering vessel with proximal segments having larger caliber and distal as get smaller. The a often leads to incomplete stent apposition (ISA). ISA alters hemodynamics creates pathological path develop complications such in-stent restenosis, more worryingly, thrombosis (ST). By employing state-of-the-art computer-aided design software, generic hoops were virtually deployed in an idealized tapered decreasing malapposition distance....

The role of balloon aortic valvuloplasty (BAV) in the era transcatheter valve replacement remains a topic debate. We sought to study safety and feasibility combined BAV percutaneous coronary intervention (BAV-PCI).

Minimisation of radiation exposure with cardiac imaging reduces the potential secondary side effects. Radiation from myocardial perfusion scintigraphy and computed tomography coronary angiography ( CTCA ) was compared. Overall doses were low both modalities. Doses lower in group, but by only a small difference 1.1 m S v. should not be primary consideration when choosing between these two

Abstract Cardiac events are commonly triggered by rupture of intracoronary plaque. Many studies have suggested that retinal small vessel abnormalities predict cardiac events. The present study examined microvascular associated with This was a single centre cross-sectional observational consecutive subjects who underwent coronary angiography and optical coherence tomography (OCT) occlusive artery disease. Subjects’ images were deidentified graded for retinopathy (Wong Mitchell...

A 75-year-old patient with hypertension and severe aortic stenosis underwent elective coronary angiography that showed mild non-obstructive disease in the mid left anterior descending artery (LAD). ventriculogram, however, demonstrated segmental systolic dysfunction dilated akinetic apex (figure 1A, see online supplementary video 1). There was no history of prior myocardial infarction had not experienced any chest pain recently. 12-lead ECG widespread deep symmetrical inverted T-waves...

A middle-aged patient with previous stent to the left circumflex artery (LCx) 12 months before suffering from angina, now presented acute-onset severe retrosternal chest pain an ECG showing ST-elevation in precordial leads (see online supplementary figure S1). He underwent emergency coronary angiography, which showed normal flow all arteries and a patent LCx stent. The anterior descending (LAD) contained hazy filling defect mid vessel (figure 1A). Following administration of heparin, mid-LAD...
