Current results and remaining challenges of trans-catheter aortic valve replacement expansion in intermediate and low risk patients

TAVR has become the standard treatment in patients at increased surgical risk (STS or EuroSCORE II 654% or logistic EuroSCORE I 65 10% or other risk factors not included in these scores such as frailty, porcelain aorta, sequelae of chest radiation) and it is increasingly being performed in patients at intermediate to low (STS or EuroSCORE II <4% or logistic EuroSCORE I < 10%) surgical risk. Although non-inferiority has been demonstrated in intermediate and low-risk patients, several challenges need to be addressed before expansion to younger patients. Current trends, trials results, and remaining challenges are summarized and discussed in this review

Preventing the deterioration of bank loan portfolio quality: a focus on unlikely-to-pay loans

This study examines determinants of: (a) new flows of unlikely-to-pay loans (UTPs), comparing them to determinants of bad loans; and (b) out-flows from UTPs to performing and bad loans. A novel panel data-set covering the period 2010–2016 is used to test hypotheses relating to lending policy, bank capitalization, bad management, and procyclical credit policy. Determinants identified by the existing literature on the wider category of all non-performing loans are in part confirmed for UTPs and in part rejected. The main findings show: (i) a positive relationship exists between bank capitalization and new flows of both UTPs and bad loans; (ii) reducing cost efficiency increases both new flows of UTPs and the worsening of UTPs towards bad loans; and (iii) having a specific unit/office to manage impaired loans increases flows from UTPs to performing loans, but does not decrease flows to bad loans. Our study is useful for banks seeking to prevent new impaired exposures, to accelerate the transition from UTPs to performing loans, and to prevent UTPs worsening to bad loans. The findings reveal the importance of sound and proactive UTP management, given the need for banks to increase provisions for covering UTPs in the near future

Experience with regorafenib in the treatment of hepatocellular carcinoma

Regorafenib is a diphenylurea oral multikinase inhibitor, structurally comparable to sorafenib, which targets a variety of kinases implicated in angiogenic and tumor growth-promoting pathways. Regorafenib was the first agent to positively show significant survival advantage as a second-line therapy in patients with unresectable hepatocellular carcinoma (HCC) who had previously failed first-line treatment with sorafenib. Recent evidence has shown that its antitumor efficacy is due to a comprehensive spectrum of tumor neo-angiogenesis and proliferation inhibition and immunomodulatory effects on the tumor microenvironment, which plays a crucial role in tumor development. This review addresses the rationale and supporting evidence for regorafenib’s efficacy in HCC that led to regorafenib’s approval as a second-line therapy. In addition, we review proof from clinical practice studies that validate the RESORCE trial results. We discuss regorafenib’s potential role in the newly emerging therapeutic strategy based on combination with immune checkpoint blockade and its possible extensibility to patient categories not enrolled in the registrative study

Beneficial prognostic effects of aspirin in patients receiving sorafenib for hepatocellular carcinoma: A tale of multiple confounders

Case–control observational studies suggested that aspirin might prevent hepatocellular carcinoma (HCC) in high-risk patients, even if randomized clinical trials are lacking. Information regarding aspirin in subjects who already developed HCC, especially in its advanced stage, are scarce. While aspirin might be a low-cost option to improve the prognosis, multiple confounders and safety concerns are to be considered. In our retrospective analyses of a prospective dataset (n = 699), after assessing the factors associated with aspirin prescription, we applied an inverse probability treatment weight analysis to address the prescription bias. Analyses of post-sorafenib survival were also performed to reduce the influence of subsequent medications. Among the study population, 133 (19%) patients were receiving aspirin at the time of sorafenib prescription. Aspirin users had a higher platelet count and a lower prevalence of esophageal varices, macrovascular invasion, and Child–Pugh B status. The benefit of aspirin was confirmed in terms of overall survival (HR 0.702, 95% CI 0.543–0.908), progression-free survival, disease control rate (58.6 vs. 49.5%, p < 0.001), and post-sorafenib survival even after weighting. Minor bleeding events were more frequent in the aspirin group. Aspirin use was associated with better outcomes, even after the correction for confounders. While safety concerns arguably remain a problem, prospective trials for patients at low risk of bleeding are warranted

Safety and Efficacy of Myval Implantation in Patients with Severe Bicuspid Aortic Valve Stenosis-A Multicenter Real-World Experience.

Bicuspid aortic valve (BAV) is the most common valvular congenital anomaly and is apparent in nearly 50% of candidates for AV replacement. While transcatheter aortic valve implantation (TAVI) is a recommended treatment for patients with symptomatic severe aortic stenosis (AS) at all surgical risk levels, experience with TAVI in severe bicuspid AS is limited. TAVI in BAV is still a challenge due to its association with multiple and complex anatomical considerations. A retrospective study has been conducted to investigate TAVI's procedural and 30-day outcomes using the Myval transcatheter heart valve (THV) (Meril Life Sciences Pvt. Ltd. Vapi, Gujarat, India) in patients with severe bicuspid AS. Data were collected on 68 patients with severe bicuspid AS who underwent TAVI with the Myval THV. Baseline characteristics, procedural, 30-day echocardiographic and clinical outcomes were collected. The mean age and STS PROM score were 72.6 ± 9.4 and 3.54 ± 2.1. Procedures were performed via the transfemoral route in 98.5%. Major vascular complications (1.5%) and life-threatening bleeding (1.5%) occurred infrequently. No patient had coronary obstruction, second valve implantation or conversion to surgery. On 30-day echocardiography, the mean transvalvular gradient and effective orifice area were 9.8 ± 4.5 mmHg and 1.8 ± 0.4 cm2, respectively. None/trace aortic regurgitation occurred in 76.5%, mild AR in 20.5% and moderate AR in 3%. The permanent pacemaker implantation rate was 8.5% and 30-day all-cause death occurred in 3.0% of cases. TAVI with the Myval THV in selected BAV anatomy is associated with favorable short-term hemodynamic and clinical outcomes

Gender Difference in the Effects of COVID-19 Pandemic on Mechanical Reperfusion and 30-Day Mortality for STEMI: Results of the ISACS-STEMI COVID-19 Registry

Background. Several reports have demonstrated the impact of the COVID-19 pandemic on the management and outcome of patients with ST-segment elevation myocardial infarction (STEMI). The aim of the current analysis is to investigate the potential gender difference in the effects of the COVID-19 pandemic on mechanical reperfusion and 30-day mortality for STEMI patients within the ISACS-STEMI COVID-19 Registry. Methods. This retrospective multicenter registry was performed in high-volume primary percutaneous coronary intervention (PPCI) centers on four continents and included STEMI patients undergoing PPCIs in March–June 2019 and 2020. Patients were divided according to gender. The main outcomes were the incidence and timing of the PPCI, (ischemia time ≥ 12 h and door-to-balloon ≥ 30 min) and in-hospital or 30-day mortality. Results. We included 16683 STEMI patients undergoing PPCIs in 109 centers. In 2020 during the pandemic, there was a significant reduction in PPCIs compared to 2019 (IRR 0.843 (95% CI: 0.825–0.861, p < 0.0001). We did not find a significant gender difference in the effects of the COVID-19 pandemic on the numbers of STEMI patients, which were similarly reduced from 2019 to 2020 in both groups, or in the mortality rates. Compared to prepandemia, 30-day mortality was significantly higher during the pandemic period among female (12.1% vs. 8.7%; adjusted HR [95% CI] = 1.66 [1.31–2.11], p < 0.001) but not male patients (5.8% vs. 6.7%; adjusted HR [95% CI] = 1.14 [0.96–1.34], p = 0.12). Conclusions. The COVID-19 pandemic had a significant impact on the treatment of patients with STEMI, with a 16% reduction in PPCI procedures similarly observed in both genders. Furthermore, we observed significantly increased in-hospital and 30-day mortality rates during the pandemic only among females. Trial registration number: NCT 04412655

Relative survival and excess mortality following primary percutaneous coronary intervention for ST-elevation myocardial infarction

Background: High survival rates are commonly reported following primary percutaneous coronary intervention for ST-elevation myocardial infarction, with most contemporary studies reporting overall survival. Aims: The aim of this study was to describe survival following primary percutaneous coronary intervention for ST-elevation myocardial infarction corrected for non-cardiovascular deaths by reporting relative survival and investigate clinically significant factors associated with poor long-term outcomes. Methods and Results: Using the prospective UK Percutaneous Coronary Intervention registry, primary percutaneous coronary intervention cases (n=88,188; 2005–2013) were matched to mortality data for the UK populace. Crude five-year relative survival was 87.1% for the patients undergoing primary percutaneous coronary intervention and 94.7% for patients 75 years: 4.69, 4.27–5.16). After four years, there was no excess mortality for ages 56–65 years (excess mortality rate ratio 1.27, 0.95–1.70), but persisting excess mortality for older groups (66–75 years: excess mortality rate ratio 1.72, 1.30–2.27; >75 years: 1.66, 1.15–2.41). Excess mortality was associated with cardiogenic shock (excess mortality rate ratio 6.10, 5.72–6.50), renal failure (2.52, 2.27–2.81), left main stem stenosis (1.67, 1.54–1.81), diabetes (1.58, 1.47–1.69), previous myocardial infarction (1.52, 1.40–1.65) and female sex (1.33, 1.26–1.41); whereas stent deployment (0.46, 0.42–0.50) especially drug eluting stents (0.27, 0.45–0.55), radial access (0.70, 0.63–0.71) and previous percutaneous coronary intervention (0.67, 0.60–0.75) were protective. Conclusions: Following primary percutaneous coronary intervention for ST-elevation myocardial infarction, long-term cardiovascular survival is excellent. Failure to account for non-cardiovascular death may result in an underestimation of the efficacy of primary percutaneous coronary intervention
