Safety and efficacy of an ultra low dose fluoroscopic protocol for chronic total occlusion recanalization.

Background: Chronic total occlusion (CTO) revascularization is a major source of radiation for both patients and physicians. Therefore, efforts to minimize radiation during CTO percutaneous coronary intervention (PCI) are highly encouraged.

Aims: To evaluate the impact of an Ultra Low fluoroscopic Dose Protocol (ULDP), based on 3.

Degenerated BioBentall graft with failing stentless bioprosthesis and dissection of the aortic conduit treated with a bail-out valve in valve procedure: a case report.

Background: The Bentall procedure is commonly performed to treat combined aortic valve and ascending aorta disease requiring surgical correction. Although the technique has been shown to provide favourable long-term outcomes, both the valvular prosthesis and the aortic conduit can go through structural degeneration. Increasing use of the biological prosthesis opened to percutaneous treatment of valvular deterioration according to a valve-in-valve (ViV) technique.

Peripheral bare-metal stent implantation for a very-late stenosis of an aortic-left main Cabrol graft: a case report.

Background: The surgical ascending aorta repair according to the Cabrol procedure involves the interposition of a prosthetic conduit between the aortic prosthesis and the native coronary ostia. Previous cases of the Cabrol conduit stenosis have been described, most of which presented as acute coronary syndromes due to thrombotic occlusion of the graft.

Case Summary: We present a case of stable exertional angina due to very-late stenosis of the coronary prosthetic conduit, successfully treated with trans-femoral percutaneous angioplasty and off-label implantation of a balloon-expandable bare-metal stent designed for peripheral artery disease.

Four-year outcomes of a single-center experience with coronary everolimus-eluting bioresorbable scaffolds.

Background: Bioresorbable scaffolds (BRS) have been introduced to overcome the limitations of drug-eluting stents and the ABSORB (Everolimus-Eluting BRS, Abbott Vascular, Santa Clara, CA, USA) was the most extensively tested. Nevertheless, major RCTs reported higher rates of target lesion failures and BRS thrombosis at 3 years follow-up, bringing to the withdrawing of the device from the market. It has been suggested that a better lesions selection and an optimized implantation technique could mitigate the displayed adverse results.

Speckle Tracking Echocardiography: Early Predictor of Diagnosis and Prognosis in Coronary Artery Disease.

Echocardiography represents a first level technique for the evaluation of coronary artery disease (CAD) which supports clinicians in the diagnostic and prognostic workup of these syndromes. However, visual estimation of wall motion abnormalities sometimes fails in detecting less clear or transient myocardial ischemia and in providing accurate differential diagnosis. Speckle tracking echocardiography (STE) is a widely available noninvasive tool that could easily and quickly provide additive information over basic echocardiography, since it is able to identify subtle myocardial damage and to localize ischemic territories in accordance to the coronary lesions, obtaining a clear visualization with a "polar map" useful for differential diagnosis and management.

Survival in acute heart failure in intensive cardiac care unit: a prospective study.

The aim of this study is to identify the best predictors of mortality among clinical, biochemical and advanced echocardiographic parameters in acute heart failure (AHF) patients admitted to coronary care unit (CCU). AHF is a clinical condition characterized by high mortality and morbidity. Several studies have investigated the potential prognostic factors that could help the risk assessment of cardiovascular events in HF patients, but at the moment it has not been found a complete prognostic score (including clinical, laboratory and echocardiographic parameters), univocally used for AHF patients.

The prognostic role of speckle tracking echocardiography in clinical practice: evidence and reference values from the literature.

Speckle tracking echocardiography (STE) is a second-level echocardiographic technique which has gradually gained relevance in the last years. It allows semi-automatic quantification of myocardial deformation and function, overcoming most of the limitations characterizing basic echocardiography and providing an early detection of cardiac impairment. Today, its feasibility and usefulness are highly supported by literature.
