Randomized data comparing outcomes of transcatheter aortic valve replacement (TAVR) with surgery in low–surgical risk patients at time points beyond 2 years is limited. This presents an unknown for physicians striving to educate as part a shared decision-making process. The authors evaluated 3-year clinical and echocardiographic from the Evolut Low Risk trial. Low-risk were randomized TAVR self-expanding, supra-annular or surgery. primary endpoint all-cause mortality disabling stroke several...

When out-of-hospital cardiac arrest (OHCA) becomes refractory, extracorporeal cardiopulmonary resuscitation (ECPR) is a potential option to restore circulation and improve the patient's outcome. However, ECPR requires specific materials highly skilled personnel, it unclear whether increased survival health-related quality of life (HRQOL) justify these costs.

Return of spontaneous circulation occurs in less than 10% patients with cardiac arrest undergoing cardiopulmonary resuscitation (CPR) for more 15 minutes. Studies suggest that extracorporeal life support during (ECPR) improves survival rate these patients. These studies, however, are hampered by their non-randomized, observational design and mostly single-center. A multicenter, randomized controlled trial is urgently warranted to evaluate the effectiveness ECPR. We hypothesize early...

Sutureless and rapid-deployment aortic valve prostheses are frequently used for the treatment of stenosis. However, postoperative left bundle branch block (LBBB) permanent pacemaker (PPM) implantation have emerged as frequent complications. The aim this study was to compare incidence new-onset LBBB PPM after sutureless replacement (sAVR) with stented bioprostheses, impact on survival.Patients undergoing isolated surgical (AVR) or concomitant AVR coronary artery bypass surgery between January...

We sought to investigate real-world outcomes of patients with degenerated biological aortic valve prostheses who had undergone valve-in-valve transcatheter implantation (ViV-TAVI) or reoperative surgical replacement (redo-SAVR) in the Netherlands.Patients ViV-TAVI redo-SAVR for a prosthesis Netherlands between January 2014 and December 2018 were eligible this retrospective study. Patients prior homograft, active endocarditis mechanical excluded. matched using propensity score. The primary...

Abstract Background Degenerative aortic valve disease accounts for 10–20% of all cardiac surgical procedures. The impact pre-existing comorbidities on the outcome patients undergoing replacement (SAVR) needs further research. Methods IMPACT registry is a non-interventional, prospective, open-label, multicenter, international with follow-up 5 years to assess SAVR INSPIRIS RESILIA outcomes. will be conducted across 25 sites in Austria, Germany, Netherlands and Switzerland intends enroll...

Abstract Objective The aim of this study was to evaluate the reasons for emergent cardiac surgery (ECS) after transcatheter aortic valve implantation (TAVI) and assess outcomes these patients. Methods All patients undergoing ECS following a complicated TAVI procedure at high-volume centre in Netherlands from 1 January 2008 April 2022 were included. Baseline procedural characteristics outcome data (procedural, 30-day 1‑year mortality, in-hospital stroke, pacemaker implantation, vascular...

Conduction disorders and the need for permanent pacemaker (PPM) implantation after surgical aortic valve replacement are well-recognized complications. However, in case of sutureless prostheses, it remains unknown whether (PM) dependency conduction disturbances resolve over time. Our aim was to evaluate Perceval recover during follow-up.Patients undergoing isolated or concomitant with coronary artery bypass surgery using valve, between January 2010 July 2018, were included. Postoperative...

Abstract OBJECTIVES We investigated the sex-related difference in characteristics and 2-year outcomes after surgical aortic valve replacement (SAVR) by propensity-score matching (PSM). METHODS Data from 2 prospective registries, INSPIRIS RESILIA Durability Registry (INDURE) IMPACT, were merged, resulting a total of 933 patients: 735 males 253 females undergoing first-time SAVR. The PSM was performed to assess impact sex on SAVR outcomes, yielding 433 243 with comparable baseline...

The use of endoscopic vein harvesting in patients undergoing coronary artery bypass grafting is increasing, often using bedside mapping. However, data on the predictive value great saphenous (GSV) mapping are scarce. This study assessed whether preoperative could predict final conduit diameter.A prospective registry was created that included 251 patients. Saphenous performed prior to at 3 predetermined sites. After and preparing GSV, outer diameters were measured. Appropriate graft size...

Aortic valve disease is frequently associated with ascending aorta dilatation and can be treated either by separate replacement of the aortic or a composite graft. The type surgery depending on exact location concomitant valvular procedures required. limited evidence for elective in elderly high-risk patient remains challenging therefore alternative strategies could warranted. We describe an strategy treatment aneurysm pathology use sutureless, collapsible, stent mounted prosthesis.
