Contemporary experience of percutaneous management of complex aortic and ventricular pseudoaneurysms associated to perivalvular leak: A case series and review of literature.
BACKGROUND
Percutaneous closure of aortic and ventricular pseudoaneurysms (PSA) has only been reported on a case report and series basis. In previous case reports, percutaneous closure has been performed successfully in patients of prohibitive surgical risk. This case series aims to show feasibility of percutaneous closure of aortic and ventricular pseudoaneurysm secondary to perivalvular leak (PVL) in a small patient population and the utility of multimodality imaging as an integral tool in procedural planning. This is the largest complex case series to date describing the feasibility and success rate of complex PSA closure, with a follow-up period of up to 4 years.
MATERIAL AND METHODS
We performed institutional review and systemic literature review to identify all paravalvular leak cases with associated pseudoaneurysm formation for which a closure procedure was performed. Ten patients were identified. Pooled analysis for cases from institutional review (n = 10) and systemic literature review (n = 39) was performed. The success rate was 100 %. At 30-days, the mortality was 0 %.
CONCLUSION
In paravalvular leak patients with subsequent pseudoaneurysm formation, exhaustive imaging evaluation is required for closure. However, it can be achievable with favorable rates of success.

Review
Data comparing MANTA device with Perclose device for large bore arterial access closure is limited. We performed meta-analysis to compare safety and efficacy of the two devices in large (⩾14 Fr sheath) arteriotomy closure post-TAVR. Relevant studies were identified via PubMed, Cochrane, and EMBASE databases until June, 2022. Data was analyzed using random effect model to calculate relative odds of VARC-2 defined access-site complications and short-term (in-hospital or 30-day) mortality. A total of 12 studies (2 RCT and 10 observational studies) comprising 2339 patients were included. The odds of major vascular complications (OR 0.99, 95% CI 0.51-1.92; = 0.98); life threatening and major bleeding (OR 0.77, 95% CI 0.45-1.33; = 0.35); minor vascular complications (OR 1.37, 95% CI 0.63-2.99; = 0.43); minor bleeding (OR 0.94, 95% CI 0.57-1.56; = 0.82); device failure (OR 0.74, 95% CI 0.49-1.11; = 0.14); hematoma formation (OR 0.76, 95% CI 0.33-1.75; = 0.52); dissection, stenosis, occlusion, or pseudoaneurysm (OR 1.08, 95% CI 0.71-1.62; = 0.73) and short-term mortality (OR 1.01, 95% CI 0.55-1.84; = 0.98) between both devices were similar. MANTA device has a similar efficacy and safety profile compared to Perclose device.

Acute neurological manifestations in patients with Behcet's syndrome are rare yet may lead to devastating outcomes. Distinguishing primary neurological deficits from spontaneous hemorrhagic insults is of particular importance for the prognosis of patients with Behcet's syndrome. Here, we investigate the clinical characteristics, management, and outcomes of nontraumatic hemorrhagic injury in patients with Bechet's syndrome. Following the case presentation, a systematic review of the literature identified cases of spontaneous hemorrhage among patients with Behcet's syndrome. Variables of interest were collected from each article to characterize patient demographics, clinical manifestations, management, and reported outcomes. Additionally, a rare case of nontraumatic intramedullary spinal bleeding in a young male with Behcet's syndrome is presented. Including our case, we analyzed 12 cases of spontaneous bleeding associated with Behcet's syndrome in 12 articles. Patient age ranged from 16 to 71 (median = 36), with a male predominance (n = 11, 91.7%). Involvement of cardiothoracic structures (n = 3, 25%), pulmonary (n = 4, 33.3%), and gastrointestinal or genitourinary vasculature (n = 3, 25%) was most common, followed by extracranial (n = 2, 16.7%) and central nervous system vasculature (n = 1, 8.3%). Clinical presentation varied depending on which specific systems or anatomical structures were involved. Anticoagulation or antiplatelet therapy was mentioned in three cases (27.3%). Erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) were noted to be elevated in six cases (54.5%). Most cases were managed surgically (n = 8, 66.7%); four cases were managed conservatively (33.3%). In our case, the patient's intramedullary bleed was allowed to dissolve without further manipulation. Of the reported outcomes, major recovery was achieved in 10 patients (83.3%), and two patients died from aneurysm or pseudoaneurysm rupture (16.7%). New-onset neurological findings in patients with Behcet's syndrome should raise suspicion for possible spontaneous hemorrhage. Our case presents the first reported instance of an abrupt onset of neurological injury secondary to intramedullary spinal cord bleed in Behcet's syndrome. A systematic review of the literature demonstrates no difference in mortality for patients managed conservatively compared to those who undergo surgical treatment.

Review
Subarachnoid hemorrhage resulting from cerebral aneurysm rupture is a significant cause of morbidity and mortality. Early identification of aneurysms on Computed Tomography Angiography (CTA), a frequently used modality for this purpose, is crucial, and artificial intelligence (AI)-based algorithms can improve the detection rate and minimize the intra- and inter-rater variability. Thus, a systematic review and meta-analysis were conducted to assess the diagnostic accuracy of deep-learning-based AI algorithms in detecting cerebral aneurysms using CTA. PubMed (MEDLINE), Embase, and the Cochrane Library were searched from January 2015 to July 2023. Eligibility criteria involved studies using fully automated and semi-automatic deep-learning algorithms for detecting cerebral aneurysms on the CTA modality. Eligible studies were assessed using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool. A diagnostic accuracy meta-analysis was conducted to estimate pooled lesion-level sensitivity, size-dependent lesion-level sensitivity, patient-level specificity, and the number of false positives per image. An enhanced FROC curve was utilized to facilitate comparisons between the studies. Fifteen eligible studies were assessed. The findings indicated that the methods exhibited high pooled sensitivity (0.87, 95% confidence interval: 0.835 to 0.91) in detecting intracranial aneurysms at the lesion level. Patient-level sensitivity was not reported due to the lack of a unified patient-level sensitivity definition. Only five studies involved a control group (healthy subjects), whereas two provided information on detection specificity. Moreover, the analysis of size-dependent sensitivity reported in eight studies revealed that the average sensitivity for small aneurysms (<3 mm) was rather low (0.56). The studies included in the analysis exhibited a high level of accuracy in detecting intracranial aneurysms larger than 3 mm in size. Nonetheless, there is a notable gap that necessitates increased attention and research focus on the detection of smaller aneurysms, the use of a common test dataset, and an evaluation of a consistent set of performance metrics.

Pacing and Clinical Electrophysiology :... Jan 2024This meta-analysis evaluated long-term efficacy and safety of cryoballoon ablation (CB) of atrial fibrillation (AF). (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
This meta-analysis evaluated long-term efficacy and safety of cryoballoon ablation (CB) of atrial fibrillation (AF).
METHODS
PubMed, Cochrane Library, and Web of Science were searched until July 31, 2023, for published works investigating efficacy and safety of CB of AF in which mean/median follow-up time was not less than 36 months. Safety was assessed by adverse events. Efficacy was assessed by AF recurrence, defined as any atrial arrhythmias lasting more than 30 s.
RESULTS
A total of 19 clinical studies were included. After an average of 58.1 months of follow-up, the overall AF recurrence rate was about 37%. The predictors of recurrence were duration of AF (HR 1.00; 95% CI [1.00 ∼ 1.01]), early recurrence of atrial fibrillation (HR 3.96; 95%CI [1.12 ∼ 14.02]), left atrial diameter (HR 1.04; 95%CI [1.02 ∼ 1.06]), and persistent AF (HR1.47; 95% CI [1.19 ∼ 1.82]). In terms of safety, the incidence of transient phrenic paralysis (PNP) was the highest, about 3%; followed by vascular complications (about 2%); pseudoaneurysm, permanent PNP, and all-cause death was (about 1%); and pericardial effusion and stroke / TIA was very low.
CONCLUSION
CB is associated with low rates of severe complications and reasonable success rates.

Meta-Analysis
OBJECTIVES
For a long time, the association of the false lumen status and the outcomes of patients suffering from aortic dissection has been unclear, so this review article aims to study whether the unobstructed of the false lumen is related to the outcome of patients suffering from aortic dissection.
METHODS
We performed this systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta Analyzes Protocols (PRISMA) statement 2009 and registered with PROSPERO (CRD42022381869). We searched PubMed, the Cochrane library, Web of Science and Embase to collect potential studies. The Newcastle-Ottawa Scale was used to assess the quality of the included studies. The main outcome is long-term survival. Data included in the study were summarized using the risk ratio or mean difference and 95% confidence interval.
RESULTS
There were 16 trials, 2829 patients in total, with a mean age of 62.1 years. Compared with completely thrombosed false lumen, patent group has better long-term survival (risk ratio (RR), 0.88; 95% CI, 0.79 to 0.97; p = 0.01; I2 = 58%) and smaller yearly aortic growth rate (mean difference (MD), 1.03; 95% CI, 0.23 to 1.82; p = 0.01; I2 = 98%). In addition, patients with a patent false lumen had a lower risk of aortic event (RR, 0.81; 95% CI, 0.68 to 0.97; p = 0.02; I2 = 37%), but higher risk of aortic rupture (RR, 7.02; 95% CI, 2.55 to 19.3; p = 0.0002; I2 = 0) and hospital death (RR, 2.72; 95% CI, 1.45 to 5.08; p = 0.002; I2 = 0).
CONCLUSION
Completely thrombosed of the false lumen is more beneficial to the long-term survival of patients with aortic dissection. And the risk of aortic rupture and hospital death in patients with patent false lumen is 7 times and 3 times that of patients with complete thrombosed false lumen. It is expected to provide individualized medical care for different types of patients according to different false lumen status to minimize death and related complications.

OBJECTIVE
The aim of this study is to evaluate the efficacy of endovascular treatment for nondissected diseases of the ascending aorta. . PubMed, Embase, and SciELO. . In this study, we conducted a search on the PubMed, Embase, and SciELO databases for all cases of ascending aortic endovascular repair included in the literature published between January 2007 and July 2023, excluding type A aortic dissection. We reviewed 56 case reports and 7 observational studies included in this study, assessing the techniques, equipment, procedural steps, and results. We summarized the age, complications, follow-up time, and access route.
RESULTS
This study includes 63 articles reporting 105 patients (mean age: 64.96 ± 17.08 years) who received endovascular repair for nondissected ascending aortic disease. The types of disease include aneurysm ( = 16), pseudoaneurysm ( = 71), penetrating aortic ulcer ( = 10), intramural hematoma ( = 2), thrombosis ( = 2), iatrogenic coarctation ( = 1), and rupture of the aorta ( = 3). The success rate of surgery is 99.05% (104/105). Complications include endoleak (10.48%, 11/105), stroke (5.71%, 6/105), postoperative infection (1.91%, 2/105), acute renal failure (0.95%, 1/105), aortic rupture (0.95%, 1/105), thrombosis (0.95%, 1/105), and splenic infarction (0.95%, 1/105). Five patients required conversion to open surgery, two patients underwent endovascular reintervention, and four of these five patients underwent surgery due to endoleak. Early mortality was 2.86% (3/105).
CONCLUSION
While the viability and results of endovascular repair for the treatment of ascending aortic disease are acknowledged in some circumstances, further research is needed to determine the safety and effectiveness of endovascular treatment for ascending aortic disease.

Review
BACKGROUND
Ruptured splenic artery aneurysms (r-SAA), although rare, are burdened by high morbidity and mortality, even despite emergent surgical repair. It is suggested that endovascular treatment can achieve reduction in peri-operative death and complication rates, as in other vascular diseases, but evidence of such benefits is still lacking in this particular setting. We report a case of an r-SAA treated by trans-arterial embolization and then converted to open surgery for persistent bleeding, and we provide a systematic review of current results of open and endovascular repair of r-SAAs.
MATERIALS AND METHODS
A 50-year-old male presenting in shock for a giant r-SAA underwent emergent coil embolization and recovered hemodynamic stability. On the following day, he underwent laparotomy for evacuation of the huge intraperitoneal hematoma, but residual bleeding was noted from the splenic artery, which was ligated after coil removal, and a splenectomy was performed. A systematic literature review of the reported mortality and complications of r-SAA undergoing open (OSR) or endovascular (EVT) treatment was performed using the main search databases. All primary examples of research published since 1990 were included regardless of sample size. The main outcome measures were mortality and reinterventions. Secondary outcomes were post-operative complications.
RESULTS
We selected 129 studies reporting on 350 patients-185 treated with OSR and 165 with EVT. Hemodynamically unstable patients and ruptures during pregnancy were more frequently treated with open repair. Overall, there were 37 deaths (mortality: 10.6%)-24 in the OSR group and 13 in the EVTr group (mortality: 12.9% and 7.8% respectively, -value: 0.84). There were 37 reinterventions after failed or complicated endovascular repair -6 treated with endovascular re-embolization and 31 with laparotomy and splenectomy (22.4%); there were 3 (1.6%) reinterventions after open repair. Overall complication rates were 7.3% in the EVT group (: 12) and 4.2% in the OSR group (: 7), and did not require reintervention. No significant differences in overall complications or in any specific complication rate were observed between the two groups.
CONCLUSIONS
Current results of r-SAA treatment show equipoise terms of morbidity and mortality between open and endovascular repair; however, in case of hemodynamic instability and rupture during pregnancy, open surgery might still be safer. Moreover, endovascular repair is still burdened by a significantly higher rate of reinterventions, mostly with conversions to open surgery.

Meta-Analysis Review
OBJECTIVE
Fenestrated and branched thoracic endovascular aortic repair (F/B-TEVAR) of the aortic arch is a viable approach in patients unsuitable for open repair. The aim was to summarise the published results of manufactured F/B-TEVAR devices for partial and total repair of the aortic arch, and to compare fenestrated with branched configurations.
DATA SOURCES
PubMed, Scopus and The Cochrane Library were searched for articles (2018 - 2021) about patients with elective, urgent, or emergency aortic requiring a proximal landing zone in the aortic arch (zone 0 - 1 - 2) and treated by F/B-TEVAR.
REVIEW METHODS
The systematic review and meta-analysis were performed according to the PRISMA guidelines. Open repair, supra-aortic trunk (SAT) debranching + standard TEVAR, and in situ physician modified and parallel grafts were excluded. Primary outcomes were technical success and 30 day mortality rate. Secondary outcomes were 30 day major adverse events, and overall survival and procedure related endpoints during follow up.
RESULTS
Of 458 articles screened, 18 articles involving 571 patients were selected. Indications for intervention were chronic dissections (50.1%), degenerative aneurysms (39.6%), penetrating aortic ulcers (7.4%), and pseudoaneurysms (2%). F-TEVAR, B-TEVAR, and F+B-TEVAR were used in 38.4%, 54.1%, and 7.5% of patients, respectively. Overall, technical success was 95.9% (95% confidence interval [CI] 0.93 - 0.97; I = 0%; p for heterogeneity (Het) = .77) and the 30 day mortality rate was 6.7% (95% CI 0.05 - 0.09; I = 0%; p Het = .66). No statistical differences were found comparing fenestrated with branched endografts, except for a higher rate of type I - III endoleaks in F-TEVAR (9.8% vs. 2.6%; p = .034). The overall survival rate and freedom from aortic related death at the one year follow up ranged between 82 - 96.4% and 94 - 94.7%, respectively. Thirteen and five studies were considered at moderate and high risk of bias, respectively.
CONCLUSION
F/B-TEVAR for the treatment of the aortic arch, according to experience in dedicated centres, now enjoys a satisfactory level of technical success together with a progressively reduced early mortality rate. There are several limitations, and further studies are needed to reach clearer conclusions.

Meta-Analysis Review
PURPOSE
To evaluate the safety of >8-F access closures using 8-F Angio-Seal.
MATERIALS AND METHODS
An electronic search was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines using Web of Science, Embase, Scopus, and PubMed databases from inception until January 17, 2022. Actionable and nonactionable bleeding events were defined in conjugation with the Bleeding Academic Research Consortium definition. Prevalence rates with corresponding 95% CIs were calculated using R software version 4.2.2. Eight articles, with 422 patients, were included in the analysis.
RESULTS
The overall groin adverse event rate was 5.92% (95% CI, 3.01-11.34). The most commonly reported adverse events were any bleeding (5.74%; 95% CI, 3.23-10.00) (nonactionable bleeding, 0.96% [95% CI, 0.10-8.30]; actionable bleeding, 2.30% [95% CI, 0.89-5.84]), pseudoaneurysm (1.18%; 95% CI, 0.49-2.81), and groin hematoma (1.28%; 95% CI, 0.23-6.79). The least commonly reported adverse events were device failure and vessel occlusion/stenosis, with rates 0.29% (95% CI, 0.01-7.41) and 0.45% (95% CI, 0.02-7.74), respectively. No studies recorded events regarding the following adverse events: mortality, infection, deep venous thrombosis, and retroperitoneal hematoma. Moreover, the results showed significant differences, based on the sheath size used, in actionable bleeding (P = .04) and the rate of need for surgical repair (P < .01).
CONCLUSIONS
Common femoral artery access of >8-F can be effectively closed with the Angio-Seal with comparable outcomes to those of <8 F; however, larger access approaching 14 F is associated with a significant increase in morbidity. Further safety is needed, especially for the larger access sizes.
