Article Synopsis
  • A study collected data from 2,626 patients who underwent Transcatheter Aortic Valve Replacement (TAVR) in Italy from 2007 to 2017, focusing on those with normal or reduced Left Ventricular Ejection Fraction (LVEF).
  • Reduced LVEF patients were further divided into ischemic and nonischemic groups, with the main goal being to track all-cause death and rehospitalizations over 8 years.
  • Results showed that patients with reduced LVEF faced a higher risk of death and rehospitalizations, particularly those with an ischemic cause, highlighting the long-term challenges for these patients post-TAVR.

Limited data are available about the impact of permanent pacemaker (PPM) implantation on long-term survival in patients with a bicuspid aortic valve (BAV) and severe aortic stenosis (AS) treated with transcatheter aortic valve replacement (TAVR). We aimed to evaluate the long-term clinical outcomes of patients with BAV with AS who underwent periprocedural PPM implantation after TAVR with a self-expandable prosthesis. Data from patients with BAV and severe AS who underwent TAVR between April 2009 and January 2022 and followed in the framework of the One Hospital ClinicalService-CoreValve Project were collected.

Background: Complete revascularization (CR) of nonculprit lesions (NCL) is strongly recommended in patients with ST-elevation myocardial infarction (STEMI) and multivessel coronary artery disease (MVD), but no definitive evidence is available regarding which diagnostic strategy should be preferred. Instantaneous wave-free ratio (iFR) has never been investigated in this setting. We aimed to describe clinical outcomes of a cohort of patients undergoing iFR-guided CR.

In patients with advanced heart failure (HF), left ventricular assist devices (LVADs) have demonstrated to be effective in improving the quality of life and reducing further hospitalizations. Although uncommon, LVAD outflow graft obstruction (OGO) is a potentially life-threatening complication and percutaneous treatment has been proposed as a standard intervention strategy in such cases. We report the case of a 69 year old man admitted due to LVAD failure causing unstable HF.

Background: The optimal management of patients with ST-elevation acute coronary syndromes and multivessel coronary artery disease is challenging. There is a growing body of evidence supporting invasive functional evaluation of multivessel disease with FFR or iFR, which it has been added to the literature. In this regard, the WAVE Study recently demonstrated the diagnostic accuracy of instantaneous wave-free ratio (iFR) functional assessment of non-culprit lesions in multivessel patients with STEMI.

Our aim was to investigate the impact of a baseline New York Heart Association (NYHA) class IV on clinical outcomes of a large real-world population who underwent transcatheter aortic valve implantation (TAVI). The primary end points were all-cause mortality, cardiovascular mortality, and re-hospitalization, evaluated at the longest available follow-up and by means of a 3-month landmark analysis. The secondary end points were: change in NYHA class, left ventricular ejection fraction, pulmonary pressure and mitral regurgitation.

Objective: Diabetics are at increased risk after stent implantation and potentially sensitive to the type of stent and dual anti-platelet therapy (DAPT). The randomized, double-blind LEADERS FREE trial compared 2432 patients at high bleeding risk (HBR) receiving either a polymer-free BA9-coated stent (DCS) or a bare metal stent (BMS) with 1 month of DAPT, and showed superior safety and efficacy of the DCS at 2 years. We report outcomes at 2 years of the pre-specified diabetic subgroup.

Background: Functional assessment of non-infarct-related artery lesions during primary percutaneous coronary intervention (PCI) might be useful to avoid revascularization of nonsignificant stenosis and staged procedures, thus reducing hospital stay. We aimed to assess the diagnostic performance of instantaneous wave-free ratio (iFR) as compared with fractional flow reserve (FFR) in this setting.

Methods: In the WAVE study, a prospective, observational, single-center registry (NCT02869906), paired iFR and FFR measurements were performed at the level of non-IRA lesions in patients with ST-segment elevation myocardial infarction both during primary PCI and during staged procedures (5-8 days after).

The increased life expectancy, urbanization, and unhealthy lifestyle characterized by a shift towards a sedentary lifestyle and decreased energy expenditure are considered the main drivers of epidemiological transition. In particular, developing countries are facing a double burden caused by coexisting under- and over-nutrition, which causes a change in the disease profile from infectious diseases to a chronic degenerative pattern. This review discusses the under- and over-nutrition context in Mauritania and India, two countries that are experiencing a nutritional transition, and where we began a collaboration with local medical staff to integrate interventional and diagnostic guidelines.

Article Synopsis
  • A study reviewed the impact of abciximab on 1-year survival rates in patients with STEMI complicated by cardiogenic shock undergoing primary PCI.
  • Out of 410 patients analyzed, those treated with abciximab had similar survival rates compared to those who were not treated with it.
  • Key predictors of death included older age, oro-tracheal intubation, and poor post-PCI TIMI flow, while abciximab use was not a significant predictor.
