Clinical outcomes of MANTA vs suture-based vascular closure devices after transcatheter aortic valve replacement: An updated meta-analysis

Objective: A recently published randomized control trial showed different results with suture-based vascular closure device (VCD) than plug-based VCD in patients undergoing transfemoral transcatheter aortic valve replacement (TAVR). The learning curve for MANTA device is steep, while the learning curve for suture based VCD is shallow as the devices are quite different. In this meta-analysis, we have compared suture-based (ProGlide and Prostar XL) vs plug-based VCDs (MANTA). Methods: We performed a meta-analysis of all published studies (using PubMed/Medline and Cochrane databases) reporting the clinical outcome of plug-based vs suture-based VCDs in transfemoral TAVR patients. Results: We included nine studies with a total of 2865 patients (plug-based n ¼ 1631, suture-based n ¼ 1234). There was no significant difference in primary outcome of all bleeding when using plugbased as opposed to suture-based VCDs (RR 1.14 [0.62e2.06] I2 ¼ 72%). There was no significant difference in the incidence of secondary outcomes between two groups including major life threatening bleeding (RR 1.16 [0.38e3.58] I2 ¼ 65%), major vascular complications (RR 0.84 [0.35e2.00] I2 ¼ 55%), minor vascular complications (RR 1.05 [0.56e1.95] I2 ¼ 42%), pseudo aneurysm (RR 1.84 [0.11e29.98] I 2 ¼ 44%), stenosis-dissection (RR 0.98 [0.66e1.47] I2 ¼ 0%), VCD failure (RR 1.71 [0.96e3.04] I2 ¼ 0%), and blood transfusion (RR 1.01 [0.38e2.71], I2 ¼ 61%). Conclusion: Large bore arteriotomy closure with plug-based VCD was not superior to suture-based VCDs in this transfemoral TAVR population. There was very frequent use of secondary VCDs in suture-based VCD group which is not practical when using MANTA. Additional high-powered studies are required to determine the safety and efficacy of MANTA device.

Right ventricular systolic pressure – Non-invasive bedside predictor of mortality and readmission in heart failure with reduced and preserved ejection fraction hospitalization

Objective: To study the prognostic role of right ventricular systolic pressure (RVSP) in patients with heart failure (HF). Background: Although RVSP is a readily available echocardiographic parameter, it is often underused. Its prognostic role in patients with heart failure is not well established compared with pulmonary artery pressure measured by right heart catheterization. Methods: This single-center retrospective cohort study included patients with acute heart failure hospitalization admitted to the hospital from January 2005 to December 2018. The primary predictor was right ventricular systolic pressure (RVSP) obtained from bedside transthoracic echocardiography at admission. We divided RVSP into two groups, RVSP <40 mm Hg (reference group) and RVSP 40 mm Hg. Primary outcome was all-cause mortality. Secondary outcomes were all-cause readmission and cardiac readmission. We conducted propensity-score matching and applied cox-proportional hazard model to compute hazard ratio (HR) with 95% confidence interval (CI). Results: Out of 972 HF patients, 534 patients had RVSP <40 mm Hg and 438 patients had RVSP 40 mm Hg. Patients with RVSP 40 mm Hg compared with RVSP <40 mm Hg were associated with higher rates of death [HR: 1.60, 95% CI: 1.22e2.09, P-value ¼ 0.001], all-cause readmissions [HR: 1.37, 95% CI: 1.09 e1.73, P-value ¼ 0.008] and cardiac readmissions [HR: 1.41, 95% CI: 1.07e1.85, P-value ¼ 0.014]. Conclusion: Higher RVSP (40 mm Hg) in HF patients was associated with higher rates of death, allcause readmissions, and cardiac readmissions. RVSP can be considered as a prognostic marker for mortality and readmission.P

Sex differences in 30-day readmission rates, etiology, and predictors after transcatheter aortic valve replacement

Background The aim of this study is to analyze sex-specific readmission rates, etiology, and predictors of readmission after transcatheter aortic valve replacement (TAVR). Readmissions after TAVR are common, contributing to increased health care utilization and costs. Many factors have been discovered as predictors of readmission; however, sex-specific disparities in readmission rates are limited. Methods Between January 2012 and September 2015, adult patients after TAVR were identified using appropriate international classifications of diseases, ninth revision, clinical modification from the National Readmission Database. Incidence of unplanned 30-days readmission rate was the primary outcome of this study. In addition, this study includes sex-specific etiology and predictors of readmissions. Multivariate logistic regression was performed to analyze adjusted readmission rates. Hierarchical 2-level logistic models were used to evaluate predictors of readmission. Results Readmission rate at 30 days was 17.3%, with slightly higher readmission rates in women (OR 1.09; CI: 1.01–1.19, p < 0.001) after multivariate adjusted analysis. Noncardiac causes were responsible for most readmissions in both genders. Etiologies for readmissions such as arrhythmias, pulmonary complications, and infections were slightly higher in women, whereas heart failure and bleeding complications were higher in men. History of heart failure, atrial fibrillation, prior pacemaker, and renal failure significantly strongly predicted readmissions in both genders. Conclusion Women undergoing TAVR have slightly higher 30-day all-cause readmission rates. These results indicate that women require more attention compared to men to prevent 30-day readmission. In addition, risk stratification for men and women based on predictors will help identify high-risk men and women for readmissions.

Duodenal perforation: role of multi detector computed tomography (MDCT).

Perforation of peptic ulcers, more specifically; ulcers of the first part of the duodenum carry mortality up to 11 %, with a higher mortality seen in patients over the age of 50 years. Main symptoms are acute onset abdominal pain and vomiting. Guarding & rigidity is present on examination. Conventional X-ray abdomen standing is the first investigation, which shows free gas under diaphragm. MDCT scan is required for identifying the presence, site and cause of gastrointestinal tract perforation. Early diagnosis and treatment is mandatory as it is a grave emergency condition.
