Background: Del Nido cardioplegia (DNC) has extensively been used for pediatric population undergoing cardiac surgery. However, its use in adult cardiac surgeries have been limited thus, its benefits are not yet fully known. This analysis was performed to evaluate the impact of DNC versus any other type of cardioplegia in adult patients who are undergoing cardiac surgery. Methods: We systematically searched PubMed, Cochrane Library, and Scopus from database inception till March 2023, and moderate to high-quality randomized controlled trials were included which compared DNC to other cardioplegia. The primary outcome was postoperative stroke and/or transient ischemic attack (TIA). Secondary outcomes included spontaneous rhythm return, postoperative myocardial infarction, all-cause mortality, postoperative atrial fibrillation, defibrillation after coronary reperfusion, postoperative intra-aortic balloon pump, postoperative kidney injury, postoperative low cardiac output syndrome, inotropic support, cardiopulmonary bypass time, cross-clamp time, blood transfusion, cardioplegia volume, hospital stay, intensive care unit stay, mechanical ventilation stay, postoperative left ventricular ejection fraction, and cardiac markers. Results: In this meta-analysis, 13 studies were included with a patient population of 2207. Stroke and/or TIA studies (risk ratio [RR]: 0.54, 95% CI [0.29, 1.00]) and all-cause mortality studies (RR: 1.30, 95% CI [0.66, 2.56]) were insignificant. From the secondary outcomes, spontaneous rhythm return (RR: 1.58, 95% CI [1.02, 2.45]), defibrillation after coronary reperfusion (RR: 0.49, 95% CI [0.30, 0.79]), inotropic support (RR: 0.70, 95% CI [0.57, 0.85]), composite risk of stroke and/or TIA and/or acute kidney injury and mortality (RR: 0.72, 95% CI [0.53, 0.99]), cross-clamp time (mean difference [MD]: −6.01, 95% CI [−11.14, −0.89]), blood transfusion (RR: 0.73, 95% CI [0.60, 0.90]), cardioplegia volume (MD: −537.17, 95% CI [−758.89, −315.45]), troponin T (MD: −1.71, 95% CI [−2.11, −1.32]), creatine phosphokinase-MB (MD: −2.96, 95% CI [−5.84, −0.07]) were significant. Whereas all other secondary outcomes were found to be insignificant. Conclusion: No significant difference was observed between patients undergoing Del Nido administration in comparison to other cardioplegia solutions for the primary outcome, stroke or/and TIA.

The assessment of left atrial strain (LAS) has emerged as an essential component in the evaluation of cardiac function, especially in pathologies such as heart failure and atrial fibrillation. This narrative review aims to outline the available methods for assessing LAS with a major emphasis on speckle-tracking echocardiography techniques. Other imaging modalities, including cardiac magnetic resonance and cardiac computed tomography, also provide important information on LA dynamics but have disadvantages with respect to cost and availability. The current narrative review underlines basic concepts such as the accurate assessment of LAS and discusses the clinical relevance of LAS by pointing out its significant diagnostic and prognostic role in several cardiovascular conditions. The aim of this article is to discuss the current integration of LAS into clinical practice with a view to further improving patient management and treatment strategies.

Abstract Seizure localization is important for managing drug‐resistant focal epilepsy. Here, the capability of a novel deep learning‐based source imaging framework (DeepSIF) for imaging seizure activities from electroencephalogram (EEG) recordings in drug‐resistant focal epilepsy patients is investigated. The neural mass model of ictal oscillations is adopted to generate synthetic training data with spatio‐temporal‐spectra features similar to ictal dynamics. The trained DeepSIF model is rigorously validated using computer simulations and in a cohort of 33 drug‐resistant focal epilepsy patients with high‐density (76‐channel) EEG seizure recordings, by comparing DeepSIF estimates with surgical resection outcome and seizure onset zone (SOZ). These findings show that the trained DeepSIF model outperforms other methods in estimating the spatial and temporal information of origins of ictal activities. It achieves a high spatial specificity of 96% and a low spatial dispersion of 3.80 ± 5.74 mm when compared to the resection region. The source imaging results also demonstrate good coverage of SOZ, with an average distance of 10.89 ± 10.14 mm (from the SOZ to the reconstruction). These promising results suggest that DeepSIF has significant potential for advancing noninvasive imaging of the origins of ictal activities in patients with focal epilepsy, aiding management of intractable epilepsy.

Abstract Aims Lipoprotein(a) (Lp(a)) levels are known to be mainly genetically determined. However, only scarce data are available on the intra-individual variability of Lp(a) levels across time. Methods and results We included adult patients (≥18 years old) who had baseline and follow-up Lp(a) measurements (between 1997 and 2024) with a minimum of 1 year apart. Patients were categorized into three groups as follows: normal (<30 mg/dL), borderline (30 to 50 mg/dL), and high Lp(a) (≥50 mg/dL). Multivariable logistic regression was conducted to assess the predictors of the intra-individual changes in Lp(a) ≥ 10 mg/dL. A total of 11 669 individuals (median age: 54 years, 60% males) were included in our analysis, with median time between measurements of 4.5 years [interquartile range (IQR): 2.2, 10.6]. The median Lp(a) was 16 mg/dL (IQR: 7, 52) at baseline, compared with 15 mg/dL (IQR: 7, 52) at follow-up. At follow-up, 96.4% of individuals with normal Lp(a) and 89.9% with high Lp(a) remained in their categories, while 51.2% with borderline Lp(a) changed their category. Of the included population, 24.9% had an intra-individual Lp(a) change ≥ 10 mg/dL. Female sex (P < 0.001), history of ASCVD (P = 0.003), statin therapy (P = 0.003), and elevated LDL cholesterol (LDL-C) levels ≥ 100 mg/dL (P < 0.001) were significantly associated with higher odds of intra-individual Lp(a) changes ≥ 10 mg/dL. Conclusion Lipoprotein(a) levels were generally stable over time; however, patients with borderline levels may require more than one Lp(a) measurement, especially if they are females, have a history of ASCVD, have elevated LDL-C levels, or are on statin therapy.

Lipoprotein (a) is a complex lipid molecule that has sparked immense interest in recent years, after studies demonstrated its significant association with several cardiovascular conditions. Lp(a) promotes cardiovascular disease through its combined proatherogenic, pro-inflammatory, and prothrombotic effects. While the measurement of Lp(a) has become widely available, effective methods to reduce its concentration are currently limited. However, emerging data from ongoing clinical trials involving antisense oligonucleotides have indicated promising outcomes in effectively reducing Lp(a) concentrations. This may serve as a potential therapeutic target in the management and prevention of myocardial infarction, calcific aortic stenosis, and cerebrovascular accidents. In contrast, the role of Lp(a) in atrial fibrillation, in-stent restenosis, cardiac allograft vasculopathy, and bioprosthetic aortic valve degeneration remains unclear. This review article aims to thoroughly review the existing literature and provide an updated overview of the evidence surrounding the association of Lp(a) and these cardiovascular diseases. We seek to highlight controversies in the existing literature and offer directions for future investigations to better understand Lp(a)’s precise role in these conditions, while providing a summary of its unique molecular characteristics.

Background Cerebral sinus venous thrombosis (CSVT) has traditionally been treated medically with systemic anticoagulation. Recent advances in endovascular therapy (EVT) may represent an alternative treatment to medical therapy for CSVT. We conducted a systematic review and meta-analysis to evaluate the use of EVT for CSVT. Methods We conducted a systematic literature review using PubMed, Embase, Scopus, and Web of Science. We included studies that reported outcomes following EVT for CSVT. The primary outcome of interest was rate of modified Rankin Scale (mRS) 0–2. Secondary outcomes of interest were rates of complete, partial, and failed recanalization, mortality, and new or expansion of hematoma. We calculated pooled rates (%) and their corresponding 95% confidence intervals (CIs). Results Thirty-eight studies with 682 patients were included. Rate of mRS 0–2 was 82.6% (95% CI, 75.3%–88.0%). Rate of complete recanalization was 60.9% (95% CI, 49.1%–71.5%), rate of partial recanalization was 34.2% (95% CI, 24.1%–45.9%), and rate of failed recanalization was 5.4% (95% CI, 3.1%–9.2%). Rate of mortality was 6.7% (95% CI, 4.1%–10.8%), and rate of new hematoma or expansion of hematoma was 5.1% (2.9%–8.8%). Conclusions In this systematic review and meta-analysis, EVT for CSVT was associated with favorable rates of mRS 0–2 and recanalization. Furthermore, EVT was associated with a promising safety profile. Future prospective, comparative studies are warranted to assess EVT for CSVT.

BACKGROUND: Previous transcatheter valve therapy registry analyses of transcatheter mitral valve in valve (MViV) replacement of degenerated bioprosthesis reported early experience in the United States. Given recent increases in transseptal MViV volumes and introduction of the SAPIEN 3 Ultra valve, it is important to determine contemporary outcomes for patients undergoing transseptal SAPIEN 3/SAPIEN 3 Ultra MViV replacement. METHODS: The Society of Thoracic Surgeons (STS)/American College of Cardiology Transcatheter Valve Therapy Registry was used to extract data for all patients undergoing transseptal SAPIEN 3/SAPIEN 3 Ultra MViV from 2015 to September 2022. Primary efficacy outcome was 1-year all-cause mortality. Secondary end points included 30-day mortality, functional class, quality of life, and mitral valve performance. Primary safety outcomes were device success and in-hospital complications. RESULTS: A total of 4243 patients with a mean±SD STS score of 9.2±7.7 underwent transseptal MViV at 455 sites. The rate of Mitral Valve Academic Research Consortium technical (96.6%) success was high, and procedural complications were low. All-cause in-hospital, 30-day, and 1-year mortality rates were 3.2%, 4.3%, and 13.4%, respectively. Significant improvements in New York Heart Association class (New York Heart Association I/II, 18% to 87%) and quality of life (Kansas City Cardiomyopathy Questionnaire score, 38 to 78) were noted at 1 year ( P <0.0001 for both) after MViV. Upon stratifying by STS scores, it was observed that the low-risk group (STS<4) had a significantly lower in-hospital mortality rate of 0.4%, whereas the intermediate-risk group (STS, 4–8) had an in-hospital mortality rate of 1.9%. From 2015 to 2022, the number of transseptal MViV cases/year increased significantly, whereas procedure times, length of stay, and intensive care unit hours shortened significantly. At the same time, there was a significant trend toward reduced in-hospital ( P =0.0005), 30-day ( P =0.004), and 1-year mortality rates ( P =0.01). CONCLUSIONS: This multicenter, prospective study reports excellent procedural outcomes, acceptable 1-year mortality rates, and a significant improvement in quality of life for patients undergoing transseptal MViV in the contemporary era. Patients in the low-risk and intermediate-risk STS score categories had significantly better outcomes compared with those in the high-risk category. MViV is a reasonable therapy for the majority of patients with degenerated bioprosthetic mitral valves, who are anatomical candidates.
