Transcatheter aortic valve implantation (TAVI) has become the leading technique for aortic valve replacement in symptomatic patients with severe aortic stenosis with conventional surgical aortic valve replacement (SAVR) now limited to patients younger than 65–75 years due to a combination of unsuitable anatomies (calcified raphae in bicuspid valves, coexistent aneurysm of the ascending aorta) and concerns on the absence of long-term data on TAVI durability. This incredible rise is linked to technological evolutions combined with increased operator experience, which led to procedural refinements and, accordingly, to better outcomes. The article describes the main and newest technical improvements, allowing an extension of the indications (valve-in-valve procedures, intravascular lithotripsy for severely calcified iliac vessels), and a reduction of complications (stroke, pacemaker implantation, aortic regurgitation).
Over the last decades, bioprosthetic heart valves (BHV) have been increasingly implanted instead of mechanical valves in patients undergoing surgical aortic valve replacement (SAVR). Structural valve deterioration (SVD) is a common issue at follow-up and can justify the need for a reintervention. In the evolving landscape of interventional cardiology, valve-in-valve transcatheter aortic valve replacement (ViV TAVR) has emerged as a remarkable innovation to address the complex challenges of patients previously treated with SAVR and has rapidly gained prominence as a feasible technique especially in patients at high surgical risk. On the other hand, the expanding indications for TAVR in progressively younger patients with severe aortic stenosis pose the crucial question on the long-term durability of transcatheter heart valves (THVs), as patients might outlive the bioprosthetic valve. In this review, we provide an overview on the role of ViV TAVR for failed surgical and transcatheter BHVs, with a specific focus on current clinical evidence, pre-procedural planning, procedural techniques, and possible complications. The combination of integrated Heart Team discussion with interventional growth curve makes it possible to achieve best ViV TAVR results and avoid complications or put oneself ahead of time from them.
(1) Background: This single-center retrospective study aimed to evaluate whether sodium–glucose cotransporter-2 inhibitors (SGLT2-i) therapy may have a nephroprotective effect to prevent contrast-induced acute kidney injury (CI-AKI) in patients with heart failure (HF) undergoing iodinated contrast medium (ICM) invasive procedures. (2) Methods: The population was stratified into SGLT2-i users and SGLT2-i non-users according to the chronic treatment with gliflozins. The primary endpoint was CI-AKI incidence during hospitalization. Secondary endpoints were all-cause mortality and the need for continuous renal replacement therapy (CRRT). (3) Results: In total, 86 patients on SGLT2-i and 179 patients not on SGLT2-i were enrolled. The incidence of CI-AKI in the gliflozin group was lower than in the non-user group (9.3 vs. 27.3%, p < 0.001), and these results were confirmed after propensity matching analysis. Multivariable logistic regression showed that only SGLT2-i treatment was an independent preventive factor for CI-AKI (OR: 0.41, 95% CI: 0.16–0.90, p = 0.045). The need for CRRT was reported only in five patients in the non-SGLT2-i-user group compared to zero patients in the gliflozin group (p = 0.05). (4) Conclusions: SGLT2-i therapy was associated with a lower risk of CI-AKI in patients with HF undergoing ICM invasive procedures.
Improved expertise and technological advancements have enabled the safe and effective performance of complex and high-risk-indicated percutaneous coronary intervention (CHIP) in patients previously considered inoperable or high-risk. Mechanical circulatory support (MCS) devices play a crucial role in stabilizing hemodynamics during percutaneous coronary intervention (PCI) -related ischemia, thereby reducing the risk of major adverse events and achieving a more complete revascularization. However, the use of MCS devices in protected PCI is not without risks, including peri-procedural myocardial infarction (MI), bleeding, and access-related complications. Despite numerous observational studies, there is a significant lack of randomized clinical trials comparing different MCS devices in various CHIP scenarios and evaluating their long-term safety and efficacy profiles. This review aims to summarize the current evidence regarding the benefits of MCS devices during CHIPs, offer a practical guide for selecting appropriate devices based on clinical scenarios, and highlight the unanswered questions that future trials need to address.
Elevated low-density lipoprotein cholesterol (LDL-C) and subclinical inflammation - measured with high-sensitivity C-reactive protein (hsCRP) - contribute to atherosclerosis progression. Despite medical therapy, high-risk patients may still have residual cholesterol risk, residual inflammatory risk (RIR), both, or neither. We aimed to study the impact of RIR in patients undergoing contemporary percutaneous coronary intervention (PCI). A comprehensive search of Pubmed, EMBASE, Cochrane and MEDLINE was performed up to December 2024. Only studies including patients with coronary artery disease undergoing PCI were considered. Inflammatory burden was evaluated with two hs-CRP measurements at baseline and follow-up (> 4 weeks apart). High RIR was defined as hsCRP ≥ 2 mg/L at 1-month follow-up. The risk ratio (RR) with a 95% confidence interval (CI) was computed using a random-effect model. We identified five studies enrolling 13,604 patients, including 5,833 with high RIR at 30 days post–PCI. At 12-month follow-up, persistent high RIR was associated with an increased risk of major adverse cardiovascular events (MACE) (random-effects RR = 1.64, 95% CI 1.33–2.03; I² = 80.2%). High RIR was also associated with increased all-cause mortality (random-effects RR = 3.25, 95% CI 2.49–4.25; I² = 67%), non-fatal myocardial infarction (random-effects RR = 1.46, 95% CI 1.00–2.12; I² = 73%), and non-fatal stroke (random-effects RR = 1.64, 95% CI 1.14–2.37; I² = 0%). Sensitivity analyses, including Baujat plots and leave-one-out analyses, identified a single study as a major contributor to heterogeneity; exclusion of this study substantially reduced heterogeneity without materially altering the direction or magnitude of the associations. In patients undergoing contemporary PCI, a high RIR was associated with a significantly higher risk of adverse cardiovascular outcomes. This data could help tailor lipid-lowering and anti-inflammatory therapies in this high-risk population.
Anthracyclines remain a cornerstone of cancer therapy but are associated with a significant risk of cardiotoxicity, which can lead to overt heart failure. The risk is modulated by cumulative dose, pre-existing cardiovascular disease, and patient-specific factors. As cancer survival improves, the long-term cardiovascular consequences of anthracycline exposure have become a growing concern, underscoring the need for effective preventive strategies. This narrative review examines lifestyle and pharmacological interventions aimed at mitigating anthracycline-induced cardiotoxicity. Evidence suggests that structured exercise programs and antioxidant-rich diets may enhance cardiovascular resilience, while beta-blockers, renin-angiotensin system inhibitors, and dexrazoxane remain central pharmacological options. Emerging therapies, including sodium-glucose co-transporter 2 inhibitors and sacubitril/valsartan, show promise but require further investigation. A comprehensive approach that integrates lifestyle modifications with pharmacological strategies within a multidisciplinary cardio-oncology framework may provide optimal protection, improving long-term cardiovascular outcomes in cancer patients receiving anthracyclines.
