The COVID-19 Pandemic has put enormous pressure on the healthcare system globally, causing many healthcare organizations all over the world to cancel or stop elective procedures in their cardiac catheterization laboratoires. This delay in elective procedures with no doubt has led to a suspension of patient care primarily to those with severe aortic stenosis, which might place them at higher risk for cardiovascular complications like sudden death and heart failure.Health Care Worker are faced with the uncertainty of contracting infections while performing procedures in patients with a confirmed diagnosis of COVID-19 or suspected cases. This unprecedented situation is very challenging for the safety of Health Care Worker. Hence, in this article, we aim to summarize some of the current guidelines as to how to triage patients in need for Trans Catheter Aortic Valve Implantation (TAVI), during this ongoing pandemic, and will address some necessary considerations related to the preparation of catheterization laboratories and personal during the COVID-19 pandemic. 相似文献

We report two cases of delayed migration of the Sapien XT device after a successful mitral valve‐in‐valve (VIV) implantation. The procedure was performed through a transapical approach. Echocardiography was used to choose the size of the Sapien XT device. Although the immediate results were satisfactory both the cases presented with severe regurgitation (1 week and 3 months). Investigations revealed atrial migration of the Sapien device in both the cases, which was confirmed at the time of reoperation. We discuss possible mechanisms, which could have resulted in the delayed migration and highlight the difference between VIV procedures in mitral position versus other positions. © 2013 Wiley Periodicals, Inc. 相似文献

PurposeAortic stenosis (AS) is the most common valvular abnormality in the elderly population. For inoperable patients or those at high-risk for surgery, transcatheter aortic valve implantation (TAVI) has become an alternative therapeutic option. The aim of the “Comprehensive geriatric assessment for transcatheter aortic valve implantation” (CGA-TAVI) registry is to evaluate the effectiveness of TAVI from the perspective of the geriatrician and to identify patient characteristics and indicators related to complications and clinical benefits for patients with symptomatic severe calcified degenerative AS undergoing TAVI.Materials and methodsThe CGA-TAVI registry is an international, multi-center, prospective, observational registry across Europe with consecutive patient enrolment. The registry will enrol up to 200 patients with AS undergoing TAVI, starting August 2013. CGA-TAVI has two co-primary objectives: (1) Establish predictive value of Comprehensive geriatric assessment (CGA) for mortality and/or hospitalization in TAVI patients. (2) Demonstrate CGA changes within 3 months after TAVI. Secondary objectives are: (1) Establish predictive value of CGA in TAVI patients for all-cause hospitalization, TAVI-related hospitalization, and nursing home admission. (2) Develop a comprehensive score for the assessment of TAVI patient prognosis.ConclusionsThe data obtained from the CGA-TAVI registry will supplement previous results to document the potential value of the effectiveness of TAVI from the perspective of geriatricians and will allow the assessment of the predictive value of CGA for mortality and/or hospitalization in elderly TAVI patients. 相似文献

In recent years, experience with transcatheter aortic valve implantation has led to improved outcomes in elderly patients with severe aortic stenosis (AS) who may not have previously been considered for intervention. These patients are often frail with significant comorbid conditions. 相似文献

Objectives: To determine the prevalence of impaired left ventricular (LV) systolic function and its impact on the in‐hospital and long‐term outcome in patients who underwent Transcatheter Aortic Valve Implantation (TAVI). Background: Although impaired LV function may be considered a contra‐indication for aortic valve replacement, the hemodynamic characteristics of transcatheter valves may offer procedural and long‐term clinical benefit in such patients. Methods: 230 consecutive patients underwent TAVI with the Medtronic‐CoreValve System. Impaired LV function was defined by a Left Ventricular Ejection Fraction (LVEF) ≤ 35% (European Multicenter Study on Operative Risk Stratification and Long‐term Outcome in patients with Low‐Flow/Low‐Gradient Aortic Stenosis). Study endpoints were selected and defined according to the Valve Academic Research Consortium recommendations. Results: Compared with patients with a LVEF > 35% (n = 197), those with LVEF ≤ 35% (n = 33) were more often male (78.8 % vs. 46.7%, P < 0.001), more symptomatic (NYHA class III or IV, 97.0% vs. 77.2%, P = 0.008) and had a higher prevalence of prior coronary artery disease (63.6% vs. 43.1%, P = 0.029). The Logistic EuroSCORE was 14.8% and 22.8, respectively (P = 0.012). No difference was observed between the two groups in in‐hospital or 30‐day mortality (3.0% vs. 9.6%, P = 0.21), the Combined Safety Endpoint at 30 days (24.2% and 24.4%, P = 0.99) and survival free from readmission at one year (69.2% and 69.7%, P = 0.85). After adjustment, LVEF ≤ 35% was not associated with an increased risk of 30‐day mortality, in‐hospital complications and survival free from readmission at follow‐up. Conclusion: The immediate and long‐term outcome after TAVI did not differ between patients with an impaired and preserved LVEF. LVEF ≤ 35% did not predict adverse immediate and long‐term outcome. These findings suggest that TAVI should not be withheld in selected patients with impaired LV function. © 2011 Wiley Periodicals, Inc. 相似文献
