Introduction: Coronary artery disease (CAD) is a main cause of morbidity and mortality. The effectiveness of coronary revascularization in chronic coronary syndromes (CCS) is still debated. Our recent study showed the superiority of coronary revascularization over optimal medical therapy (OMT) in reducing cardiovascular (CV) mortality and myocardial infarction (MI). The recent publication of the ORBITA‐2 trial suggested superiority of percutaneous coronary revascularization (PCI) in reducing angina and improving quality of life. Therefore, we aimed to provide an updated meta‐analysis evaluating the impact of PCI on both clinical outcomes and angina in CCS. Methods: Relevant studies were screened in PubMed/Medline until 08/01/2024. Randomized controlled trials (RCTs) comparing PCI to OMT in CCS were selected. The primary outcome was CV death. Secondary outcomes were MI, all‐cause mortality, stroke, major bleeding and angina severity. Results: Nineteen RCTs involving 8616 patients were included. Median follow‐up duration was 3.3 years. Revascularization significantly reduced CV death (4.2% vs. 5.5%; OR =.77; 95% CI.62–.96, p =.02). Subgroup analyses favoured revascularization in patients without chronic total occlusions (CTOs) (p =.052) and those aged <65 years (p =.02). Finally, a follow‐up duration beyond 3 years showed increased benefit of coronary revascularization (p =.04). Secondary outcomes analyses showed no significant differences, except for a lower angina severity in the revascularization group according to the Seattle Angina Questionnaire (SAQ) (p =.04) and to the Canadian Cardiovascular Society (CCS) classification (p =.005). Conclusions: PCI compared to OMT significantly reduces CV mortality and angina severity, improving quality of life in CCS patients. This benefit was larger without CTOs, in patients aged <65 years and with follow‐up duration beyond 3 years. [ABSTRACT FROM AUTHOR]

Cardiomyopathies are the structural and functional disorders of the myocardium. Etiopathogenesis is complex and involves an interplay of genetic, environmental, and lifestyle factors eventually leading to myocardial abnormalities. It is known that non-coding (Nc) RNAs, including micro (mi)-RNAs and long non-coding (lnc) RNAs, play a crucial role in regulating gene expression. Several studies have explored the role of miRNAs in the development of various pathologies, including heart diseases. In this review, we analyzed various patterns of ncRNAs expressed in the most common cardiomyopathies: dilated cardiomyopathy, hypertrophic cardiomyopathy and arrhythmogenic cardiomyopathy. Understanding the role of different ncRNAs implicated in cardiomyopathic processes may contribute to the identification of potential therapeutic targets and novel risk stratification models based on gene expression. The analysis of ncRNAs may also be helpful to unveil the molecular mechanisms subtended to these diseases. [ABSTRACT FROM AUTHOR]

This study aimed to assess the impact of urgency on early and midterm outcomes of the Candy-Plug (CP) technique for distal false lumen (FL) occlusion in thoracic endovascular aortic repair for aortic dissection. The CP registry was reviewed, and patients were categorized into elective and urgent/emergent groups for analysis. End points included technical success, clinical success, early (30-day) computed tomography angiography findings, early (30-day) mortality, adverse events, and aortic remodeling in patients with available computed tomography angiography follow-up and reintervention. A total of 155 patients received a custom-made CP, of whom 32 patients (44% male, mean age 61 ± 9 years) were treated urgently and 123 patients (63% male, mean age 62 ± 11 years) electively. The primary CP rate was higher in the urgent group (28/32, 88%, in the urgent group vs 96/123, 78%, in the elective group, P =.051). The mean contrast volume was higher in the urgent group (157 ± 56 mL in the urgent group vs 130 ± 71 mL in the elective group, P =.017). Technical success was achieved in all patients in both groups. Clinical success was achieved in 25 of 32 (78%) patients in the urgent group vs 113 and 123 (92%) in the elective group (P =.159). The early mortality rate was 13% (4 of 32 patients) in the urgent group vs 1% (1 of 123 patients) in the elective group (P =.120). There was no statistically significant difference regarding the early adverse events between the urgent and elective CP groups. Early aortic-related reinterventions were required in 6 of 32 (19%) patients in the urgent group vs 6 of 123 (5%) in the elective group (P =.094). Thoracic aortic aneurysm sac regression was lower in the urgent group (5/28, 18%, in the urgent group vs 63/114, 55%, in the elective group, P =.001). Stable thoracic aortic aneurysm sac was higher in the urgent group (22/28, 79%, in the urgent group vs 47/114, 41%, in the elective group, P =.000). An increase in thoracic aortic aneurysm sac occurred in 1 of 28 (4%) patients in the urgent group vs 4 of 114 (4%) patients in the elective group (P =.096). The urgent use of the CP technique for distal FL occlusion in aortic dissection was feasible and effective. The decrease in aortic FL sac diameter may be affected by the urgent use of CP due to limited sizing availability. However, it achieved a high rate of aortic remodeling. [ABSTRACT FROM AUTHOR]

Background: Transfemoral access (TFA) is a valuable alternative to upper extremity access (UEA) for branched endovascular aortic repair (bEVAR). However, TFA requires large introducer sheaths, which can reduce blood flow to lower limbs and the pelvis. This study aimed to evaluate the efficacy of sheath downsizing to maintain lower limb perfusion during TFA–bEVAR. Methods: A single-center retrospective review was conducted including patients managed with TFA-performed bEVAR between December 2020 and May 2021. Intra-operative lower limb perfusion was assessed using non-invasive ankle blood pressure measurements and great toe pulse oximetry, with measurements being taken prior to puncture (baseline), one minute after 10F-sheath insertion, three minutes after the main body delivery system insertion, and three minutes after downsizing to a 14F sheath. Outcomes included the incidence of limb perfusion reduction (LPR), defined as a drop in the ankle–brachial index (ABI) < 0.5 or peripheral oxygen saturation (SpO2) < 90%. Results: Out of 47 patients, 24 met the inclusion criteria. LPR occurred in 4.2% of cases after 10F-sheath placement, and 87.5% after main body delivery system placement, and decreased to 12.6% after downsizing to a 14F sheath. No periprocedural major bleeding occurred. Two patients required revision for inadequate hemostasis post-operatively. SCI occurred in 16% of patients, all recovered by discharge. Pre-operative hypogastric artery occlusion was related to persistent LPR after downsizing (100% vs. 16%, p = 0.009). Conclusions: Downsizing the introducer sheath during bEVAR is feasible and safe to restore lower limb and pelvic perfusion. Further research is needed to clarify the access downsizing value during bEVAR. [ABSTRACT FROM AUTHOR]

Purpose: To describe a novel technique to repair a juxtarenal abdominal aortic aneurysm (JAAA) after failed endovascular aortic repair (EVAR) with severely kinked anatomy. Technique: We present a patient who underwent an EVAR with a Medtronic Talent device 15 years ago and a proximal cuff extension 3 years earlier for an abdominal aortic aneurysm. Computed tomography (CT) done for a known gastritis showed a 12 cm JAAA, with a migrated endograft and a type Ia endoleak (EL). Endovascular repair was performed, accessing and navigating the aneurysmal sac outside the previous graft. The type I EL was reached and the suprarenal aorta catheterized. A 4-vessel inner-branched EVAR device was deployed in the distal thoracic aorta and their target vessels bridged through femoral access. A distal bifurcated component was deployed and both iliac limbs were extended to the native distal iliac arteries. Completion angiogram as well as early and 12-month CT showed a fully patent straight course branched EVAR with no ELs. Conclusion: Complex aortic reinterventions in the presence of previous EVAR can be performed by choosing a straighter course along and parallel to the previous endograft. Several technical aspects must be considered to successfully perform this type of reinterventions. Clinical Impact: We present a technique of a complex endovascular aortic repair in a failed EVAR with kinked anatomy, navigating through the thrombosed aneurysmal sac, outside the previously placed endograft and thus obtaining a straighter path for a new branched endograft. The novelty lies in a different approach to repair a failed EVAR with a branched graft through an uncommon access on the side of the previous endograft, avoiding repeated displacement or occlusion of the new endograft. We exemplify the feasibility of such a complex procedure and highlight important steps to perform it, whether in the abdominal or even thoracic Aorta. [ABSTRACT FROM AUTHOR]

Background: Among the endovascular approaches for the management of endoleak type 2 (EL 2), transcaval embolization (TCE) has shown encouraging outcomes. However, the literature is still limited. This study aimed to present the early and mid-term outcomes of TCE for EL 2 after endovascular aortic repair. Methods: A retrospective, single-center analysis of consecutive patients managed with TCE for EL 2 after standard or complex endovascular aortic repair, from August 2015 to March 2024, was conducted. The indication for TCE was the presence of an EL 2 related to ≥5 mm sac increase, compared to the first imaging after aneurysm exclusion or the smallest diameter during follow-up. Patients managed with TCE for other types of endoleaks were excluded. The primary outcomes were technical and clinical successes during follow-up. Results: Forty-three patients were included (mean age: 75.1 ± 6.0 years, 90.7% males). Technical success was 97.7%. Selective embolization was performed in 48.8% and non-selective in 51.2%. No death was recorded at 30 days. The estimated clinical success was 90.0% (standard error; SE: 6.7%) and the freedom from EL 2 was 89.0% (SE 6.4%) at 36 months. Cox regression analysis showed that the type of embolization (selective vs. non-selective), type of previous repair (f/bEVAR vs. EVAR), and use of anticoagulants did not affect follow-up outcomes. Reinterventions related to EL 2 were performed in 12.5%; three underwent an open conversion. Conclusions: TCE was related to high technical success and limited peri-operative morbidity, regardless of the type of initial endovascular aortic repair. Clinical success was encouraging with reinterventions for EL 2 affecting 12.5% of patients. [ABSTRACT FROM AUTHOR]

The management of the false lumen (FL) when dealing with aortic dissection is a crucial aspect since inducing its thrombosis is necessary in order to achieve aortic remodeling. One of the pitfalls of endovascular treatment of aortic dissection (AD) is retrograde distal FL perfusion and pressurization, which prevents FL thrombosis and thus aortic remodeling, while being associated with aneurysmal degeneration of the FL and poor long-term outcomes. Currently, there is no CE/FDA approved device for FL closure, however different techniques and devices have been proposed to overcome this challenge, the most known of which is the Candy Plug (CP). This review aims to describe the CP device, its implantation technique, and the available data in the literature (PubMed, Cochrane, and EMBASE databases; last queried, December 31, 2023). While the treatment of AD remains technically challenging, the use of the CP technique to close any distal FL reperfusion proved to be feasible and safe with excellent rates of both technical and clinical success. Furthermore, recent studies have shown a quick learning curve with this technique. [ABSTRACT FROM AUTHOR]
