RESUMO
Tricuspid regurgitation (TR) negatively affects patient outcomes. Surgical tricuspid valve repair/replacement carries a high operative risk and is not a viable option for many high-risk patients. Percutaneous approaches provide an attractive alternative solution for such patients since they represent a valid alternative to open heart surgery without the significant risks carried by surgery. A number of percutaneous devices are currently under clinical development. This review will discuss about the latest development in the field of percutaneous tricuspid valve repair with possible future developments.
RESUMO
An 81-year-old woman presented with acute pulmonary edema. Echocardiography revealed severe functional mitral regurgitation, the mechanism of which was unusual. An atypical bileaflet tethering caused by disharmonic annular remodeling, concomitant aortic dilatation, and reduced aorto-mitral angle without left ventricular dysfunction or dilatation was found. A transcatheter edge-to-edge repair was nonetheless successfully performed.
RESUMO
Aims: Dual antiplatelet therapy (DAPT) can be shortened up to 1â month in high-bleeding risk (HBR) patients receiving a contemporary biodegradable-polymer sirolimus-eluting stent. We aimed to summarize the evidence on a similar DAPT regimen after biodegradable-polymer everolimus-eluting stent (EES) implantation in patients at HBR. Methods and results: We pooled the individual participant data from the available trials evaluating this strategy, namely, the SENIOR and the POEM trials. Inclusion criteria were ≥1 biodegradable-polymer EES implantation and ≤1-month duration of DAPT. The primary endpoint was the 1-year composite of cardiovascular death, myocardial infarction, or stroke. Major bleeding was defined as Bleeding Academic Research Consortium (BARC) type 3-5 bleeding. Landmark analyses were performed at 1â month, the time point for intended DAPT interruption. We included 766 participants (age 77.5 ± 8.2â years, women 31.9%), 323 from the SENIOR and 443 from the POEM trial. The primary endpoint occurred in 45 participants (6.0%; 95% confidence interval [CI], 4.3-7.7%) through 1â year of follow-up, with 21 (2.8%; 95% CI, 1.6-3.9%) events during the first month and 24 (3.4%; 95% CI, 2.0-4.7%) thereafter. The incidences of cardiovascular death, myocardial infarction, and stroke were 2.2% (95% CI, 0.36-2.50%), 3.1% (95% CI, 1.8-4.3%), and 1.2% (95% CI, 0.4-2.0%), respectively. BARC type 3-5 bleeding ocuurred in 1.1% (95% CI, 0.3-1.8%) at 1â month and 2.9% (95% CI, 1.6-4.1%) at 1â year. Conclusion: HBR patients receiving biodegradable-polymer EES had few ischemic and bleeding events when given 1â month of DAPT. One-month DAPT after biodegradable-polymer EES implantation seems safe in patients at HBR.
RESUMO
Balloon angioplasty achieves luminal enlargement by fracturing the atherosclerotic intima at its point of least resistance, thereby creating a dissection plane and space with dehiscence of the intima from the media. This barotraumatic dissection triggers an inflammatory and proliferative reaction, resulting in a restenosis process at medium-term. In the era of plain old balloon angioplasty, quantitative angiographic studies at follow-up demonstrated that - the greater the acute luminal gain was after balloon angioplasty, the greater the late luminal loss was at follow-up. The interventional cardiologists coined the following motto "the more you gain, the more you lose". However, in the current era of drug coated balloon (DCB), it appears that this vexing conundrum could have been abrogated. A recently published DCB study in small de novo vessel has demonstrated that there was a slightly negative correlation between the volume of dissection assessed by optical coherence tomography and the angiographic late luminal loss (now gain) after Paclitaxel coated balloon treatment. In other words, the barotraumatic dissection does not necessarily herald a restenosis process in the era of DCB. This article revisits the mechanism of balloon angioplasty and explores how DCB with Paclitaxel may change the paradigm of balloon angioplasty as default treatment in CAD percutaneous treatment.
RESUMO
AIMS: Glucagon-like peptide-1 receptor agonists (GLP1-ra) have shown to reduce cardiovascular (CV) events in patients with diabetes, including heart failure (HF) hospitalizations. However, whether such benefit consistently occurs in patients with history of HF remains uncertain. We performed a systematic review and meta-analysis to assess the impact of GLP1-ra on CV outcomes in patients with and without HF history. METHODS AND RESULTS: All randomized, placebo-controlled trials evaluating GLP1-ra and reporting CV outcomes stratified by HF history were searched in Pubmed from inception to November 12th, 2023. The primary outcome was HF hospitalizations. Secondary outcomes included CV death, the composite of CV death and hospitalizations for HF, and major adverse cardiovascular events (MACE). Hazard ratio (HR) and 95% confidence interval (CIs) were used as effect estimates and calculated with a random-effects model. 68,653 patients (GLP1-ra = 34,301, placebo = 34,352) from 10 trials were included. GLP1-ra reduced HF hospitalization (no HF: HR = 0.79, 95% CI 0.63-0.98; HF: HR = 1.00, 95% CI 0.82-1.24, pinteraction = 0.12), CV death (no HF: HR = 0.81, 95% CI 0.71-0.92; HF: HR = 0.97, 95% CI 0.81-1.15, pinteraction = 0.11), and the composite of HF hospitalizations and CV death (no HF: HR = 0.80, 95% CI 0.72-0.89; HF: HR = 1.00 95% CI 0.88-1.15, pinteraction = 0.010) only in patients without history of HF, despite a significant interaction between HF history and treatment effect was detected only for the latter. MACE were reduced in both subgroups without significant interaction between HF history and treatment effect (no HF: HR = 0.86, 95% CI 0.78-0.96; HF: HR = 0.83, 95% CI 0.72-0.95, pinteraction = 0.69). CONCLUSION: GLP1-ra do not decrease HF-hospitalization risk, despite a potential benefit in patients without history of HF, but are effective in reducing ischemic events irrespective of the presence of HF.

BACKGROUND: Percutaneous left atrial appendage closure (LAAC) has been suggested as an alternative to long-term oral anticoagulation for nonvalvular atrial fibrillation, but comparative data remain scarce. We aimed to assess ischemic and bleeding outcomes of LAAC compared with vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs) for the prevention of cardioembolic events in patients with atrial fibrillation. METHODS AND RESULTS: Embase and MEDLINE were searched for randomized trials comparing LAAC, VKAs, and DOACs. The primary efficacy end point was any stroke or systemic embolism. Treatment effects were calculated from a network meta-analysis and ranked according to the surface under the cumulative ranking curve. Seven trials and 73 199 patients were included. The risk of the primary end point was not statistically different between LAAC versus VKAs (odds ratio [OR], 0.92 [95% CI, 0.62-1.50]) and LAAC versus DOACs (OR, 1.11 [95% CI, 0.71-1.73]). LAAC and DOACs resulted in similar risk of major or minor (OR, 0.93 [95% CI, 0.61-1.42]) and major bleeding (OR, 0.92 [95% CI, 0.58-1.46]); however, after exclusion of procedural bleeding, bleeding risk was significantly lower in those undergoing LAAC. Both LAAC and DOACs reduced the risk of all-cause death compared with VKAs (LAAC versus VKAs: OR, 0.70 [95% CI, 0.53-0.91]; DOACs versus VKAs: OR, 0.90 [95% CI, 0.85-0.95], respectively). DOACs ranked as the best treatment for stroke or systemic embolism prevention (66.9%) and LAAC for reducing major bleeding (63.9%) and death (96.4%). CONCLUSIONS: As a nonpharmacological alternative to oral anticoagulation for atrial fibrillation, LAAC showed similar efficacy and safety compared with VKAs or DOACs. Prospective confirmation from larger studies is warranted.

BACKGROUND: Previous studies have investigated a 1 to 6-month short dual antiplatelet therapy (S-DAPT) after percutaneous coronary intervention (PCI) with modern drug eluting-stents to reduce bleeding events. OBJECTIVES: To investigate cardiovascular outcomes in patients at high bleeding risk (HBR) according to the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria after PCI with the Synergy bioresorbable-polymer everolimus-eluting stents (EES). METHODS: We applied ARC-HBR criteria in the population of the prospective, single-arm, multicenter POEM (Performance of Bioresorbable Polymer-Coated Everolimus-Eluting Synergy Stent in Patients at HBR Undergoing Percutaneous Coronary Revascularization Followed by 1-Month Dual Antiplatelet Therapy) trial. The primary endpoint was a composite of cardiac death, myocardial infarction, or definite or probable stent thrombosis at 12 months. RESULTS: The original POEM cohort included 356 patients (80.4 %) fulfilling ARC-HBR criteria. Oral anticoagulant (OAC) usage and age ≥75 years were the most frequent major and minor ARC-HBR criteria, respectively. The ARC-HBR group was mainly represented by men (71.1 %), with 74.4 ± 9.3 years and a high burden of cardiovascular risk factors. DAPT was prescribed in 79.3 %, and single antiplatelet (SAPT) with OAC in 18.7 %. 12-month follow-up was completed in 96.2 %. The primary endpoint occurred in 5.2 % (95 % CI 3.29-8.10) of patients, whereas bleeding Academic Research Consortium type 3-5 occurred in 2.7 % (95 % CI, 1.39 %-5.05 %). CONCLUSION: Previous results of the POEM trial showed positive outcomes regarding ischemic and bleeding events with an S-DAPT regimen after Synergy EES. These results are also confirmed in sub-group analysis when ARC-HBR criteria are applied.
RESUMO
BACKGROUND: Current European guidelines support transcatheter aortic valve implantation (TAVI) in intermediate-to-low-risk patients ≥75 years-old, but its prognostic relevance is unknown. METHODS: Intermediate-to-low-risk (The Society of Thoracic Surgeons score <8%) patients enrolled in the HORSE registry were included. We compared the populations aged under 75 with those over 75. The primary endpoint was all-cause mortality. RESULTS: A total of 2685 patients were included: 280 (8.6%) < 75 and 2405 ≥ 75 years. Through a mean follow-up of 437 ± 381 days, 198 (8.2%) and 23 (8.2%) patients died in the two arms without statistically significant differences (log-rank p = 0.925). At Cox regression analysis, age did not predict the occurrence of all-cause death, neither as a continuous variable (HR 1.01, 95% CI 0.99-1.04, p = 0.294) nor dichotomizing according to the prespecified cutoff of 75 years (HR 0.97, 95% CI 0.63-1.51, p = 0.924). Time-to-event ROC curves showed low accuracy of age to predict all-cause mortality (area under the curve of 0.54 for both 1-year and 2-year outcomes). CONCLUSIONS: TAVI has comparable benefits across age strata for intermediate-to-low-risk patients. The age cutoff suggested by the current guidelines is not predictive of the risk of adverse events during hospital stays or of all-cause mortality through a mid-term follow-up.
RESUMO
BACKGROUND: Value-based healthcare (VBHC) is an approach that focuses on delivering the highest possible value for patients while driving cost efficiency in health services. It emphasizes improving patient outcomes and experiences while optimizing the use of resources, shifting the healthcare system's focus from the volume of services to the value delivered. Our study assessed the effectiveness of implementing a VBHC-principled, tailored preoperative evaluation in enhancing patient care and outcomes, as well as reducing healthcare costs. METHODS: We employed a quality improvement, before-and-after approach to assessing the effects of implementing VBHC strategies on the restructuring of the preoperative evaluation clinics at Humanitas Research Hospital. The intervention introduced a VBHC-tailored risk matrix during the postintervention phase (year 2021), and the results were compared with those of the preintervention phase (2019). The primary study outcome was the difference in the number of preoperative tests and visits at baseline and after the VBHC approach. Secondary outcomes were patient outcomes and costs. RESULTS: A total of 9722 patients were included: 5242 during 2019 (baseline) and 4,480 during 2021 (VBHC approach). The median age of the population was 63 (IQR 51-72), 23% of patients were classified as ASA 3 and 4, and 26.8% (2,955 cases) were day surgery cases. We found a considerable decrease in the number of preoperative tests ordered for each patient [6.2 (2.5) vs 5.3 (2.6) tests, p < 0.001]. The number of preoperative chest X-ray, electrocardiogram, and cardiac exams decreased significantly with VBHC. The length of the preoperative evaluation was significantly shorter with VBHC [373 (136) vs 290 (157) min, p < 0.001]. Cost analysis demonstrated a significant reduction in costs, while there was no difference in clinical outcomes. CONCLUSIONS: We demonstrated the feasibility, safety, and cost-effectiveness of a tailored approach for preoperative evaluation. The implementation of VBHC enhanced value, as evidenced by decreased patient time in preoperative evaluation and by a reduction in unnecessary preoperative tests.
