In patients with cryptogenic stroke, transcatheter (TC) closure of a patent foramen ovale (PFO) has not been shown to better prevent recurrent vascular events than medical therapy. However, ...randomized controlled trials (RCT) to date have included few vascular events, and lack of power has been raised as an important concern.
To conduct a systematic review and meta-analysis of existing RCT published studies assessing the recurrence of vascular events after TC PFO closure when compared to medical therapy.
Using the search terms "patent foramen ovale", "PFO", "stroke", "percutaneous closure" and "transcatheter closure", Medline, Pubmed, Embase, and Cochrane databases were reviewed from inception through April 2013, with no language restrictions. Only studies in adult humans were considered. Additional references were obtained from the bibliographies of studies reviewed. The following criteria were used for study selection: 1) randomized controlled trial, 2) subjects were adult patients with cryptogenic stroke who were randomized to TC PFO closure or medical treatment (antiplatelet therapy and/or anticoagulation), and 3) reported outcomes included cardiac death, all death, stroke, transient ischemic attack, and peripheral embolism. Methodological and descriptive data, adverse events (including raw data and risk estimates), as well as procedural success and complications were abstracted in duplicate from each study independently, and agreement was tested. We followed rigorously the recommended guidelines for reporting and conducting and assessing quality of meta-analysis of RCT. The primary endpoints pre-specified in advance were recurrent vascular events, and composite endpoint of death, and recurrent vascular events.
Three studies were identified as meeting selection criteria. These included a total of 2,303 patients, with 1,150 patients randomized to TC PFO closure and 1,153 patients randomized to medical therapy. Mean follow-up was 3.5 years. Baseline characteristics (age, sex, and cardiovascular risk factors) were similar across studies. Intention-to-treat analyses showed a statistically significant risk reduction in stroke and/or transient ischemic attack in the TC PFO closure group when compared to medical treatment, pooled HR = 0.59, 95%CI (0.36-0.97), P = 0.04. The combined outcome of death, and vascular events, showed a borderline statistically significant benefit for TC PFO closure when compared to medical treatment, pooled HR = 0.67, 95%CI (0.44-1.00), P = 0.05 Subjects with a substantial PFO shunt seem to benefit the most with TC PFO closure, pooled HR = 0.35, 95%CI (0.12-1.03), P = 0.06, however, it did not reach statistical significance.
These results suggest that in patients with cryptogenic stroke, TC PFO closure may be beneficial in reducing the risk of recurrent vascular events when compared to medical treatment. The benefit of TC PFO closure may be greater in patients with a substantial shunt.
Abstract Background Neutrophil-lymphocyte (NLR) and platelet-lymphocyte ratios (PLR) mark systemic inflammation. Patients with high NLR and PLR have worse cardiovascular disease and outcomes. We ...assessed the role of these ratios in predicting outcomes after transcatheter aortic valve replacement (TAVR). Methods The association between NLR and PLR with baseline characteristics, 30-day outcomes, and 1-year readmission/survival was determined in patients that underwent TAVR between 2007 and 2014 and had baseline complete blood count with differential. A subgroup analysis determined the association between change in NLR and PLR (discharge-baseline) and 1-year outcomes. Results In 520 patients that underwent TAVR, a higher NLR (p = 0.01) and PLR (p = 0.02) were associated with a higher STS-PROM score, and with increased occurrence of the 30-day early-safety outcome (by VARC-2), even after adjusting for STS-PROM score, valve generation (Sapien vs. Sapien XT), and access (transfemoral vs. non-transfemoral) (NLR: OR 1.29, 95% CI 1.04–1.61; PLR: OR 1.27, 95% CI 1.01–1.60) but not with 1-year readmission or survival. In our subgroup analysis (N = 294), change in PLR was not associated with the 1-year outcomes but a high change in NLR was associated with worse 1-year survival/readmission and 1-year survival, even after adjusting for STS-PROM score, valve generation and access (HR 1.22, 95% CI 1.04–1.44 and HR 1.26, 95% CI 0.99–1.6, respectively). Conclusions NLR and PLR correlate with surgical risk. An elevated NLR and PLR were associated with the occurrence of 30-day adverse outcomes, similar to the STS-PROM score. A high variation of NLR from baseline to discharge may help stratify patients that underwent TAVR in addition to traditional risk factors.
Objectives
To examine the trends in utilization and outcomes of tricuspid valve (TV) transcatheter edge‐to‐edge repair (TEER).
Background
Surgery for isolated tricuspid regurgitation is associated ...with high morbidity and mortality and is rarely performed. TV TEER is an attractive alternative.
Methods
The Nationwide Readmissions Database was queried using the International Classification of Diseases, 10th Revision, procedure code for TV TEER for years 2016–2019. The main outcomes were trends in utilization and in‐hospital all‐cause mortality.
Results
We identified 918 hospitalizations for TV TEER. There was an uptrend in its utilization from 13 cases in the first quarter of 2016 to 122 cases in the last quarter of 2019 (p trend < 0.001). Concomitant mitral valve (MV) TEER was performed in 42.1% of admissions. The overall in‐hospital mortality was 2.1%. Surgical TV replacement was needed in 1.1% of admissions; none of them died during the index hospitalization. Unplanned rehospitalizations were common at 30 days (15.7%); 38.2% of those were due to heart failure. There was no difference in in‐hospital mortality between isolated TV TEER and combined MV and TV TEER (1.7% vs. 2.6%, p = 0.359). However, admissions receiving combined procedure had lower length of stay and urgent readmission rate.
Conclusion
The current study showed that there was an increase in the utilization of TV TEER over 2016–2019 in the United States. TV TEER was associated with low rates of in‐hospital mortality; however, the rate of urgent readmission remains high, mainly due to heart failure.
High-risk percutaneous coronary interventions (HR-PCI) are prone to hemodynamic instability, resulting in poor outcomes. Acute mechanical circulatory support (AMCS) devices are used during HR-PCI to ...improve outcomes. However, the clinical criteria for extended AMCS have not been well characterized. The aim of this study was to describe the prevalence and clinical correlates of extended AMCS in patients undergoing elective or urgent HR-PCI.
We retrospectively analyzed 507 patients enrolled in the catheter-based ventricular assist device (cVAD) registry who underwent elective or urgent HR-PCI with prophylactic use of Impella. The study population was divided into two groups: Impella support removed immediately after PCI (Group A, n = 464) and extended support after PCI (Group B, n = 43). Multivariable regression analysis was used to identify independent predictors of extended AMCS.
Baseline characteristics were similar between the groups. Non-ST-elevation myocardial infarction in 26.3% in Group A vs 41.8% in Group B (p = 0.03). PCI of left main was common in Group A (p = 0.02), whereas the right coronary artery was common in Group B (p < 0.001). The mean duration of Impella support 1.1 ± 0.6 h in Group A vs 11.4 ± 16.8 h in Group B (p < 0.001). Death and vascular complications were higher with extended Impella support. Revascularization of chronic total occlusion (CTO) was an independent predictor of extended Impella support (OR 3.2, 95% CI 1.20–8.53).
About 9% of patients enrolled in the cVAD registry undergoing elective or urgent HR-PCI received extended Impella support. In-hospital mortality was about 12% in patients requiring extended Impella support. CTO was associated with a higher likelihood of extended AMCS. The hemodynamic benefits of extended AMCS support must be weighed in terms of risk of complications.
•About 9% of elective/urgent high-risk PCI patients receive extended Impella support.•Higher likelihood of extended Impella support during revascularization of CTO•Benefits of extended Impella support must be weighed against risk of complications.•Procedural planning, adequate arterial access and management is critical during HR-PCI.
Contemporary data on the national trends in pulmonary embolism (PE) admissions and outcomes are scarce. We aimed to analyze trends in mortality and different treatment methods in acute PE. We queried ...the Nationwide Readmissions Database (2016 to 2019) to identify hospitalizations with acute PE using the International Classification of Diseases, Tenth Revision, Clinical Modification codes. We described the national trends in admissions, in-hospital mortality, readmissions, and different treatment methods in acute PE. We identified 1,427,491 hospitalizations with acute PE, 2.4% of them (n = 34,446) were admissions with high-risk PE. The rate of in-hospital mortality in all PE hospitalizations was 6.5%, and it remained unchanged throughout the study period. However, the rate of in-hospital mortality in high-risk PE decreased from 48.1% in the first quarter of 2016 to 38.9% in the last quarter of 2019 (p-trend <0.001). The rate of urgent 30-day readmission was 15.2% in all PE admissions and 19.1% in high-risk PE admissions. In all PE admissions, catheter-directed interventions (CDI) were used more often (2.5%) than systemic thrombolysis (ST) (2.1%). However, in admissions with high-risk PE, ST remained the most frequently used method (ST vs CDI: 11.3% vs 6.6%). In conclusion, this study showed that the rate of in-hospital mortality in high-risk PE decreased from 2016 to 2019. ST was the most frequently used method for achieving pulmonary reperfusion in high-risk PE, whereas CDI was the most frequently used method in the entire PE cohort. In-hospital death and urgent readmissions rates remain significantly high in patients with high-risk PE.
There was no significant difference in EF, cardiac output, cardiac index and pulmonary capillary wedge pressure and post HRPCI adverse events except death and vascular complication that were higher ...in group B (table 2).
We report an unusual case of incomplete endothelialization of the Watchman device >3 years after its implantation. Animal data suggest that device endothelialization occurs ∼45 days ...post-implantation; however, data on humans are lacking. Guidelines on anticoagulation are based on expectation from animal studies. (Level of Difficulty: Advanced.)
