Prosthesis-patient mismatch after transcatheter aortic valve replacement: prevalence and medium term prognostic impact
AbstractProsthesis-patient mismatch (PPM) occurs when the effective orifice area of the prosthesis is too small in relation to the patient's body surface area. There are few data available on the frequency and prognostic impact of PPM after transcatheter aortic valve implantation (TAVI). Our aim was to determine the prevalence of PPM and to investigate its association with medium-term clinical course of patients undergoing TAVI. We included 185 patients undergoing TAVI (79 ± 5 years, 49% male, 98% CoreValve) between April-2008 and December-2014. The effective orifice area (EOA) was determined by transthoracic echocardiogr...

Analysis of Neurologic Complications After Surgical Versus Transcatheter Aortic Valve Replacement
Ove the last decade, transcatheter aortic valve replacement (TAVR) has emerged as the recommended approach over surgical aortic valve replacement (SAVR) for many patients with aortic stenosis. While initial trials demonstrated a higher incidence of stroke with TAVR compared to SAVR, the incidence of stroke appears to have improved over time. With the increasing number of patients expected to undergo TAVR in the coming decades, it is important to review the incidence and etiology of stroke after SAVR and TAVR.

Thromboembolic and bleeding risk stratification according to the EHRA valvular heart disease classification in patients with atrial fibrillation
ConclusionThis systematic analysis in real life conditions shows that distinguishing AF patients according to the new EHRA valve classification could be relevant for creating more homogenous groups of patients in terms of TE and bleeding risk. This clearer classification than the previous one should be useful as in clinical research for harmonization of studies, as well as in clinical practice for targeted choices of OAC therapy.

Clinical outcomes of heart-team-guided treatment decisions in high-risk patients with aortic valve stenosis in a health-economic context with limited resources for transcatheter valve therapies.
CONCLUSIONS: Limited resources for transcatheter valve therapies in Belgium push a significant number of patients to SAVR, while TAVI in even higher risk patients translates into similar outcomes and shorter hospital stay. These findings underscore the need for broadening indications for TAVI, as well as readjustment of the budgetary allocations for hospitals in Belgium.

Immediate Improvement in Left Atrial Function After Transcatheter Aortic Valve Replacement on Doppler Echocardiography.
CONCLUSIONS: There is immediate improvement in LA function and an increase in LAA velocities after TAVR. This improvement may benefit hemodynamics immediately after TAVR, but may also increase the short-term stroke risk (as recently shown in two independent studies) in patients with LAA thrombus or low emptying velocities. Therefore, evaluation of LA function and LAA thrombus may be warranted to identify patients at high risk for periprocedural stroke and guide the need for anticoagulation therapy.

A Lumped Parameter Model to Study Atrioventricular Valve Regurgitation in Stage 1 and Changes Across Stage 2 Surgery in Single Ventricle Patients
Conclusion: In patients with moderate to severe AVVR, restoration of atrioventricular valve competence prior to, or at the time of, Stage 2 surgery would likely lead to improved haemodynamics and clinical outcome as the models suggest that uncorrected AV- R can worsen across Stage 2 surgery. This was found to be independent of the AVVR degree and mechanisms.
