AbstractBoth transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) have been proven to effectively correct von Willebrand Factor (vWF) pathologies, however there is limited data simultaneously comparing outcomes of both approaches. We prospectively enrolled patients with severe aortic stenosis referred for TAVI (n  = 52) or SAVR (n = 48). In each case, vWF antigen (vWF:Ag), vWF activity (vWF:Ac) and activity-to-antigen (vWF:Ac/Ag) ratio were assessed at baseline, 24 h and 72 h after procedure. VWF abnormalities were defined as reduced vWF:Ac/Ag ratio (

AbstractVery limited but promising experiences with the use of direct factor Xa inhibitors for the treatment of heparin-induced thrombocytopenia (HIT) have been reported. This contribution features our first experience with the use of apixaban (without a pre-treatment with parenteral anticoagulant) to treat a case of HIT which developed in a patient after multiple heart replacement surgery. Apixaban was effective, well tolerated and safe. An apixaban-calibrated chromogenic anti-Xa activity assessment was used to monitor apixaban activity throughout the therapy. Patient continued on apixaban for the prevention of thrombosis...

AbstractPurpose of reviewThe use of cardiac CT is well established in the TAVR sphere and gaining traction as an integral part of pre-procedural planning for left 13 atrial appendage closure (LAAC) and transcatheter mitral valve replacement (TMVR. We aim to review the recent evidence regarding the accuracy of cardiac CT for left atrial sizing and device selection and discuss the contribution of cardiac CT to decreasing complication rates in real-world experience as compared with clinical trials.Recent findingsPre-procedural CT imaging has evolved to become an integral part of LAA closure and TMVR. For LAA closure, CT imagi...

AbstractBackgroundUntreated symptomatic high-grade aortic stenosis remains a lethal disease requiring individually adapted valve replacement. High-risk surgical patients benefit from transcatheter aortic valve replacement (TAVR), but there is no uniform standard for patient selection and valve sizing and it is still unclear whether transthoracic (TTE) or transesophageal (TEE) echocardiography is superior in preprocedural aortic annulus sizing. As preprocedural sizing of the native aortic annulus diameter is crucial to outcome and survival, we report the results of a direct comparison between preprocedural sizing with TTE a...

FOR PATIENTS with severe aortic valve stenosis (AS) and significant comorbid conditions who are determined to be at a high or prohibitive surgical risk, transcatheter aortic valve replacement (TAVR) represents a viable and durable treatment option. The anesthetic management of these cases is often complex because the procedure may be complicated by hemodynamic instability or circulatory collapse. In particular, TAVR in patients with severely reduced left ventricular ejection fraction (LVEF) poses significant challenges, and optimal treatment strategies are not established fully.

ConclusionThe IECF is simple, particularly at reoperations, in borderline patients and those needing concomitant intracardiac procedures. Early results are promising. These patients need constant surveillance.

We report a case of an 84-year-old Japanese female patient with transcatheter valve embolization treated with thoracic endovascular stenting. She was diagnosed with severe aortic stenosis and referred to our hospital. Transapical transcatheter aortic valve implantation (TA-TAVI) was selected because she had multiple comorbidities and peripheral vascular disease. During TA-TAVI, the transcatheter valve (TV) came loose and lodged in the distal aortic arch. The TV was floating and unstable, thereby affecting her hemodynamics. After a second TV was placed in the appropriate position with no trouble, we tried fixing the TV usin...

CONCLUSION: Mortality in CS patients due to decompensated severe AS is high, regardless of interventional treatment strategy. Both eBAV and eTAVR seem feasible. As eTAVR is associated with better initial improvements in hemodynamics and simultaneously avoids sequential interventions, it might be favorable to eBAV in select patients. If eTAVR is not available, eBAV might serve as a "bridge" to elective TAVR. PMID: 31611428 [PubMed - as supplied by publisher]
