Case Report: Emergency High-Risk Percutaneous Coronary Intervention Following Transcatheter Aortic Valve Implantation in Bicuspid Anatomy.

ABSTRACT: Background: Transcatheter aortic valve implantation (TAVR) continues to develop as a valuable alternative to surgical aortic valve replacement (SAVR) in an increasingly wide spectrum of patients with severe symptomatic aortic stenosis (AS). AS frequently coexists with coronary artery disease, and performing technically challenging percutaneous coronary intervention (PCI) following TAVR will become more frequent with increased use of TAVR. Case Summary: We herein report the case of a 53-years-old man with complex medical history including type 1 diabetes and dialysis-dependent renal failure and prior Evolut-R TAVR for critical bicuspid aortic valve stenosis who underwent intravascular ultrasound study (IVUS)-guided PCI to a critical distal left main stem (LMS) and proximal left anterior descending (LAD) lesion after presenting with ventricular fibrillation (VF) secondary to an acute coronary syndrome (ACS). Discussion: Selective engagement of coronary ostia through the side cells of TAVR prosthesis can be challenging, especially in an emergency setting. The particular challenges associated with this case are described, as well as an up-to-date literature search on strategies and equipment that can help in this situation.

Project description:BackgroundBicuspid aortic valve (BAV) is common congenital malformation, bicuspid aortic stenosis accounts for a substantial proportion of patients with aortic valve stenosis (AS). Bicuspid AS are more likely to have aortic dilatation with slightly less elliptical annuli, which might lead to paravalvular aortic valve regurgitation (AR) and permanent pacemaker implantation (PPM) after TAVI with higher mortality. Our study aims to understand the therapeutic efficacy and safety of transcatheter aortic valve implantation (TAVI) with a supra-annular structure-based sizing strategy in Chinese AS patients with BAV versus tricuspid aortic valve (TAV).MethodsSeventy-four consecutive tricuspid AS patients and 44 bicuspid AS patients were included and enrolled in the study for analysis. Both groups underwent TAVI performed using balloon sizing less than mild paravalvular AR to assess the proper prosthesis size. The myocardial function within 1 year postoperative were sequentially evaluated using the New York Heart Association (NYHA) class, and echocardiography measurements. The incidence rates of complications at 30 days and 1 year were analyzed. During the 1-year follow-up, the time of death from any cause or complications in both groups was recorded.ResultsThe study found that the percentage of patients with class III-IV of NYHA dropped after TAVI in both groups, and no significant difference between both groups at 1 year. Compared with the tricuspid AS group patients, Bicuspid group patients had more improvement in mean aortic valve gradient from baseline to 1year (-47.47±13.38 vs. -50.22±19.25 mmHg, P<0.05). There were no significant differences in 30-day and one-year compliance outcomes except a lower incidence of AR at post-procedure and 30 days in the tricuspid AS group as the Bicuspid AS group. There were no statistically significant differences in the time of death from any cause or significant complications between groups.ConclusionsTAVI has acceptable therapeutic efficacy and safety and is feasible for AS patients with BAV in China.

Project description:ObjectiveAlthough patients with significant coronary artery disease and aortic stenosis have traditionally undergone open valve replacement and bypass grafting, percutaneous coronary intervention (PCI) and transcatheter aortic valve replacement (TAVR) are increasingly considered. Because of the lack of data regarding timing of PCI/TAVR, in the present study we evaluated associations of staged and concomitant PCI/TAVR on outcomes in a nationally representative cohort.MethodsAdults who underwent TAVR and PCI were identified using the 2016 to 2018 Nationwide Readmissions Database. If PCI/TAVR occurred on the same day, patients were considered Concomitant and otherwise considered Staged. Staged were further classified as Early-Staged if both occurred in the same hospitalization or Late-Staged if TAVR ensued PCI in a subsequent hospitalization. Multivariable regression models were developed to evaluate the association of TAVR timing on outcomes. The primary end point was in-hospital mortality whereas perioperative complications including acute kidney injury and hospitalization costs were secondarily considered.ResultsOf an estimated 5843 patients, 843 (14.4%) were Concomitant and 745 (12.7%) and 4255 (72.8%) were Early-Staged and Late-Staged, respectively. Although age and TAVR access were similar, Concomitant had a lower proportion of chronic kidney disease and more commonly underwent single-vessel PCI. Staged showed similar risk-adjusted mortality but greater odds of acute kidney injury (Early-Staged adjusted odds ratio: 2.68; 95% CI, 1.57-4.55 and Late-Staged: 1.97; 95% CI, 1.29-2.99) compared with Concomitant. Although post-TAVR hospitalization duration was similar, total length of stay and costs were increased in Staged.ConclusionsConcomitant PCI/TAVR was associated with similar rates of in-hospital mortality but reduced rates of acute kidney injury and lower resource utilization. While evaluating patient-specific factors, concomitant PCI/TAVR might be reasonable in select individuals.
