: Percutaneous coronary intervention (PCI) is a widely used revascularization strategy for coronary artery disease. The choice between imaging-guided and physiology-guided PCI has been a subject of debate. This meta-analysis aims to systematically compare outcomes between imaging and physiology-guided PCI and management of intermediate coronary lesions (ICLs).

Article Synopsis
  • The study compared transcatheter aortic valve replacement (TAVR) to surgical aortic valve replacement (SAVR) in low-risk patients, finding no significant differences in all-cause mortality, disabling stroke, or major cardiovascular events between the two procedures.
  • TAVR patients experienced more paravalvular leaks but had fewer cases of new-onset atrial fibrillation compared to those undergoing SAVR.
  • Overall, TAVR demonstrated similar long-term safety and effectiveness to SAVR, along with a greater effective orifice area but akin transvalvular mean gradients.

Article Synopsis
  • The study reviews current literature on the outcomes of surgical aortic valve replacement (SAVR) versus transcatheter aortic valve replacement (TAVR) specifically for patients with bicuspid aortic stenosis (BAS), focusing on different valve morphologies in TAVR patients.
  • It analyzed eight studies comparing SAVR and TAVR outcomes, revealing no significant differences in death, stroke, or acute kidney injury rates between both methods, though TAVR had more permanent pacemaker implantations and SAVR had higher bleeding events.
  • The findings suggest that while TAVR is comparable to SAVR in short-term outcomes for BAS, it is associated with a higher rate of pacemaker use and lower rates of bleeding.

Background: Chronic pre-procedural and acute post-procedural myocardial injury are frequently observed in patients with aortic stenosis undergoing transcatheter aortic valve implantation (TAVI). The aim of our study was to investigate the prognostic role of high sensitivity cardiac troponins (hs-cTns) elevation before and after TAVI.

Methods: 106 patients with severe aortic stenosis who underwent TAVI were enrolled.

Introduction: Despite a successful percutaneous coronary intervention (PCI), several studies reported that the recurrence of angina after revascularization, even complete, is a particularly frequent occurrence in the first year after PCI.

Methods: The aim was to evaluate the efficacy of treatment with ranolazine in addition to conventional anti-ischemic therapy in patients who underwent coronary angiography for persistent/recurrent angina after PCI and residual ischemia only due to small branches not suitable for further revascularization. Forty-nine consecutive patients were included in our registry, adding the ranolazine (375 mg b.

Objectives: This study sought to compare clinical outcome of polymer-free amphilimus-eluting stent (PF-AES) versus biodegradable-polymer biolimus-eluting stent (BD-BES) in "all-comer" diabetes mellitus (DM) and non-DM patients who underwent percutaneous coronary intervention.

Background: The PF-AES has shown promising preliminary results in patients with DM.

Methods: Data from 2 multicentre-national registries (the ASTUTE and the INSPIRE-1) were used to analyse 1776 patients stratified in non-DM and DM.

Article Synopsis
  • A study evaluated the clinical outcomes of patients requiring short dual antiplatelet therapy (S-DAPT) after receiving a Cre8 polymer-free amphilimus eluting stent (AES) to assess its safety and effectiveness.
  • The analysis involved two groups: one with patients on S-DAPT due to high bleeding risk (106 patients) and another on the recommended longer dual antiplatelet therapy (R-DAPT, 1102 patients).
  • Results showed no significant difference in major ischemic events between the groups at one year, but the S-DAPT group had a higher rate of major bleeding within the first three months; further research through randomized trials is suggested to confirm these findings.

Erectile dysfunction (ED) is defined as the inability to get and maintain a sufficient erection to ensure an acceptable sexual activity for the subject and the partner. Although ED does not represent per se a serious disease, it carries a notable and severe influence on quality of life, with significant implications on familiar and social relationship; DE may cause depression, shame, impairment of personal esteem and relational problems. Among many possible etiologies of ED, atherosclerotic disease of penile arteries represents one of the most frequent causes, so it should always be looked for in patients with multiple risk factors for cardiovascular disease or an established coronary or peripheral artery disease.

Background: Despite several improvements in drug-eluting stent (DES) technology, patients with diabetes mellitus (DM) are affected by higher rate of adverse events after PCI with DES, mainly in terms of target lesion revascularization (TLR). The Cre8 stent, a polymer-free amphilimus-eluting stent (AES), has shown promising preliminary results in DM patients. The ASTUTE registry was conceived to assess clinical performance of this polymer-free AES in DM in a "real-world" multicenter-independent cohort of patients.

A 51-year-old male patient presented to the emergency room with an anterior ST-elevation myocardial infarction. After a loading dose of both ticagrelor and aspirin, the patient underwent primary-PCI on the left anterior descending coronary artery with stent implantation. After successful revascularization, medical therapy included beta-blockers, statins, and angiotensin II receptor antagonists.

Background: Contrast-induced acute kidney injury (CI-AKI) represents an important cause of hospital-acquired AKI. The aim of this study was to evaluate the incidence of CI-AKI after coronary angiography (CA) or percutaneous coronary intervention (PCI) and the role of patient-/procedure-related risk factors.

Methods: For 11 months, patients undergoing CA or PCI were prospectively evaluated for CI-AKI, and factors possibly affecting CI-AKI were analyzed.

Background: Percutaneous coronary intervention (PCI) is a highly effective therapy for acute ST-elevation myocardial infarction. Adjunctive therapy with platelet glycoprotein (GP) IIb/IIIa inhibitor can result in increased vessel patency and improved outcomes in ST-elevation myocardial infarction patients undergoing PCI. The investigation of novel dosing and delivery strategies of this therapy may help to further improve outcomes.

Objective: To evaluate the long-term outcomes after different modalities of treatment of drug-eluting stent (DES) in-stent restenosis (ISR) in a 'real world' setting.

Methods: Actually, few and conflicting data are available about the management of in-stent restenosis (ISR) after DES implantation. In our 'real world' registry 1082 consecutive patients who received a DES implantation were included.

In this case report, we describe the use of coronary techniques and devices in the treatment of a complex popliteal artery bifurcation. In particular, we demonstrate that the Venture wire control catheter is a useful tool not only in coronary lesions but also in wiring angulated peripheral lesions.

Background: In patients with ST-segment elevation myocardial infarction (STEMI), primary percutaneous coronary intervention (PCI) may cause thrombus dislodgment leading to microvascular function impairment, which is a negative independent predictor of myocardial function recovery. Compared with conventional stenting, pretreatment with aspiration thrombectomy during primary PCI significantly improves coronary epicardial flow and myocardial tissue perfusion parameters. We sought to evaluate the angiographic findings of two different manual aspiration thrombectomy devices (Diver-Invatec (DI) and Export-Medtronic (EM)) in STEMI patients undergoing primary angioplasty.

Drug-eluting stents (DES) present a slightly higher incidence of stent thrombosis compared to bare metal stents and some cases of DES thrombosis are described in the literature. Therefore, there is consensus in recommending treatment with clopidogrel for at least 6 months in addition to life-long aspirin administration. We describe a case of very late paclitaxel-eluting stent thrombosis despite 21 months of clopidogrel treatment, which occurred just 2 weeks after its withdrawal, causing an acute coronary syndrome that was promptly resolved with an urgent invasive strategy.

Objective: Elderly patients are increasingly referred for revascularisation yet have been underrepresented in some large clinical trials. Although the advent of drug-eluting stents has dramatically reduced clinical events related to restenosis, older age remains one of the most important correlates of adverse outcome, even after an elective percutaneous coronary intervention (PCI). We sought to evaluate the impact of paclitaxel-eluting stents on coronary restenosis in elderly patients undergoing elective PCI.
