Effects of short-term oral anticoagulation following surgical bioprosthetic aortic valve replacement
CONCLUSION: Our study demonstrated that short-term OAC use after bAVR was associated with lower all-cause mortality. The prevalence of 1-year embolism/ischemic stroke/ICH were comparable despite of OAC use.PMID:36057527 | DOI:10.1016/j.jfma.2022.08.006

Systemic blood pressure in severe aortic stenosis: Haemodynamic correlates and long ‐term prognostic impact
ConclusionsIn severe AS patients, lower MAP reflects lower systemic vascular resistance and valvulo-arterial impedance, which may help to preserve stroke volume and filling pressures despite reduced left ventricular performance, and lower MAP is a predictor of higher long-term post-AVR mortality.

Direct oral anticoagulants in patients with a left-sided bioprosthetic heart valve: a systematic review and meta-analysis
AbstractTo compare the efficacy/effectiveness and safety of DOACs versus VKAs in patients with a previously and newly surgically implanted BHV with or without AF. A systematic search on MEDLINE and EMBASE was performed till November 2022. Treatment effects were estimated with relative risk (RR) and 95% confidence intervals (CIs). Statistical heterogeneity was assessed with theI2 statistic. Four randomized controlled trials (RCTs), 2 subgroup analysis from ARISTOTLE and ENGAGE-AF-TIMI 48 and 4 observational studies were included for a total of 5808 patients, 1893 on DOACs and 3915 on VKAs. AF prevalence was 98.28%. In the o...

Minimally invasive, surgical, and transcatheter aortic valve replacement: Network meta-analysis
CONCLUSIONS: MS was protective against 30-day mortality, stroke, AKI, and long-term mortality compared to FS; TAVR showed higher rates of 30-day PVL and PPM but was protective against AKI. Conversely, MT showed higher rates of 30-day PVL and major bleeding. With the emergence of TAVR, the appropriate benchmarks for SAVR comparison in future trials should be the minimally-invasive SAVR approaches to provide clinical equipoise.PMID:37611742 | DOI:10.1016/j.jjcc.2023.08.010

Transcatheter aortic valve implantation without balloon pre‐dilation: A single‐center pilot experience
Conclusions: These results suggest that direct CoreValve implantation in patients with severe aortic stenosis is feasible and may lead to hemodynamic and clinical improvement in patients who are poor candidates for aortic valve surgery, pending confirmation in larger series with longer follow‐up. © 2013 Wiley‐Liss, Inc.

Transesophageal Echocardiography for Cardiac Thromboembolic Risk Assessment in Patients With Severe, Symptomatic Aortic Valve Stenosis Referred for Potential Transcatheter Aortic Valve Implantation
Stroke is a devastating complication after transcatheter aortic valve implantation (TAVI) and might partially be related to cardiac embolization. The aim of this single-center prospective study was to determine the incidence of intracardiac thrombi and left atrial spontaneous echo contrast (SEC), both known predictors of cardiac embolic stroke, in patients referred for potential TAVI. One hundred four consecutive patients with severe symptomatic aortic valve stenosis and at high or very high risk for surgery were included and underwent transesophageal echocardiography. In 11 patients (10.6%), intracardiac thrombi were dete...

Urgent surgery compared with fibrinolytic therapy for the treatment of left-sided prosthetic heart valve thrombosis: a systematic review and meta-analysis of observational studies
Conclusion Urgent surgery was not superior to FT at restoring valve function, but substantially reduced the occurrence of thrombo-embolic events, major bleeding, and recurrent PVT. In experienced centres, urgent surgery should probably be preferred over FT for treating left-sided PVT, pending the results of randomized controlled trials.

Comparison of Transcatheter and Surgical Aortic Valve Replacement in Severe Aortic Stenosis A Longitudinal Study of Echocardiography Parameters in Cohort A of the PARTNER Trial (Placement of Aortic Transcatheter Valves)
This study sought to compare echocardiographic findings in patients with critical aortic stenosis following surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR).BackgroundThe PARTNER (Placement of Aortic Transcatheter Valves) trial randomized patients 1:1 to SAVR or TAVR.MethodsEchocardiograms were obtained at baseline, discharge, 30 days, 6 months, 1 year, and 2 years after the procedure and analyzed in a core laboratory. For the analysis of post-implantation variables, the first interpretable study (≤6 months) was used.ResultsBoth groups showed a decrease in aortic valve gradients ...
