Percutaneous coronary intervention in STEMI patients may be complicated by the presence of calcium. The Shockwave IVL technique seems to be a safe and useful option, even in STEMI cases, to achieve procedural success. Nevertheless, extra support techniques may be needed in order to deliver the Shockwave balloon.
BACKGROUND Chronic total occlusions (CTOs) are prevalent angiographic findings in patients with suspected coronary artery disease. Conflicting results of randomized controlled trials and registries have not clarified the therapeutic approach for patients with CTO in clinical practice. Therefore, we sought to analyze variables influencing the decision-making process and their relationship with clinical outcomes according to the type of selected therapy. METHODS A total of 1248 consecutive patient...
The adoption of distal transradial access (TRA) as default approach for coronary angiography and interventions was recently published. As a refinement of conventional (proximal) TRA, this technique has advantages in terms of patient and operator comfort and risk of radial artery occlusion. We report herein a very challenging case of coronary angiography followed by complex percutaneous coronary intervention via right distal TRA, with aberrant (lusoria) subclavian artery, in the setting of non-ST...
Coronary-cameral fistula (CCF) is a rare congenital communication between a coronary artery and a cardiac chamber or a great vessel. Most patients are asymptomatic and these lesions are incidentally detected during coronary angiography, with the reported incidence being up to 0.2%. The most frequent draining sites are right ventricle, right atrium, and pulmonary arteries, with less frequent drainage to the left side of the heart. The majority of CCFs are hemodynamically inconsequential and do no...

BACKGROUND Total thrombotic occlusion of the left circumflex (LCX) artery may present without ST-segment elevations; the clinical outcomes of such patients remain unclear. OBJECTIVE To examine the difference in clinical outcomes between patients with acute myocardial infarction (MI) due to LCX occlusion or stenosis with and without ST-segment elevation. METHODS The present study is based on an observational, retrospective cohort comprising all patients admitted to 2 centers between 2009 and 2019...
The inability to advance the dedicated wire of the transradial sheath in a radial artery with a good pulsatile blood flow is a very rare event. In this case, the advancement of a high-performance 0.014 inch coronary wire is the only option to gain the vessel. Then, if the transradial sheath is stuck in the proximal radial artery wall, balloon angioplasty of the radial artery may allow successful reinsertion of the transradial sheath. This technique allows the preservation of radial artery access...

BACKGROUND Patients with atrial fibrillation (AF) are at high risk of thromboembolism, with most thrombi forming in the left atrial (LA) appendage. LA appendage closure is an alternative therapy to oral anticoagulation for stroke prevention in AF patients with contraindication to oral anticoagulation. LA function is critical for cardiovascular function, and recent studies suggested a direct relationship between LA function and AF recurrence. Deformation imaging characterizes and quantifies myoca...

BACKGROUND Complex chronic total occlusion (CTO) cases often require dual access. Evidence suggests that radial access is associated with lower success rates in complex CTOs. Our primary outcome was to determine efficacy of biradial access compared with femoral access. METHODS This was a retrospective, single-center, observational study. Patients who underwent dual-access CTO percutaneous coronary intervention (PCI) between January 2014 and January 2018 were enrolled. They were separated into bi...

BACKGROUND Transcatheter aortic valve implantation (TAVI) is now routinely performed in patients with aortic stenosis with low mortality and complication rates. Although periprocedural risks have been substantially minimized, procedure- and contrast-induced acute kidney injury (AKI) remains a major concern. AKI remains a frequent complication of contrast-guided interventional procedures and is associated with a significantly adverse prognosis. We review the currently available clinical data rela...

BACKGROUND Primary coronary slow-flow phenomenon (CSFP) is defined as delayed opacification of contrast media in at least 1 coronary vessel in the absence of obstructive epicardial coronary artery disease (CAD) during coronary angiography. Epicardial fat tissue (EFT) surrounding coronary vessels provides paracrine effects. Released cytokines diffusing in the vessel wall may induce local inflammatory reactions that potentially result in endothelial dysfunction. The latter is thought to be the und...
