In a patient with a small-calibre radial artery and a 360 degrees radio-ulnar loop, we combined the balloon-assisted tracking (BAT) technique (used to track a catheter trough the loop) with the use of a 6.5 F PB sheathless guiding catheter, in order to allow the extensive catheter manipulations needed for PCI despite the ongoing artery spasm....

Aims The anatomical correlates of perfusion defect (PD) at myocardial contrast echocardiography (MCE) in the subacute phase of ST-elevation myocardial infarction (STEMI) are currently unknown. The study aimed at assessing whether, in the subacute phase of STEMI, within MCE PD microvessels are anatomically damaged or if some vasodilation can be...

Background: Leftmain (LM) atherosclerotic lesions affect clinical outcomes. Frequency domain-optical coherence tomography (FD-OCT) allows detailed characterization of non-ostial coronary atherosclerotic lesions. The clinical impact of FD-OCT assessment of LM bifurcation disease on the revascularization decision is unknown. Methods: Patients who...

Objectives: To angiographically assess myocardial perfusion in patients with Tako-Tsubo syndrome (TTS) in comparison with control individuals and patients with ST-elevation myocardial infarction (STEMI). Background: Coronary microvascular dysfunction has been proposed as the pathophysiological mechanism underlying TTS. Methods: We...

Background: The decision-making process of patients with angiographically-intermediate coronary lesions (ICL) is clinically challenging and may benefit from adjunctive invasive techniques. Fractional-flow-reserve (FFR) represents the gold standard to evaluate ICL but frequency-domain optical-coherence-tomography (OCT) is a novel, promising,...
