Objective: Avoiding a catastrophic outcome may be a more realistic goal than achieving functional independence in the treatment of acute stroke in octogenarians. This study aimed to investigate predictors of catastrophic outcome in elderly patients after an endovascular thrombectomy with an acute anterior circulation large vessel occlusion (LVO). Materials and Methods: Data from 82 patients aged ≥ 80 years, who were treated with thrombectomy for acute anterior circulation LVO, were analyzed. The association between clinical/imaging variables and catastrophic outcomes was assessed. A catastrophic outcome was defined as a modified Rankin Scale score of 4-6 at 90 days. Results: Successful reperfusion was achieved in 61 patients (74.4%), while 47 patients (57.3%) had a catastrophic outcome. The 90-day mortality rate of the treated patients was 15.9% (13/82). The catastrophic outcome group had a significantly lower baseline diffusion-weighted imaging-Alberta stroke program early CT score (DWI-ASPECTS) (7 vs. 8, p = 0.014) and a longer procedure time (42 minutes vs. 29 minutes, p = 0.031) compared to the non-catastrophic outcome group. Successful reperfusion was significantly less frequent in the catastrophic outcome group (63.8% vs. 88.6%, p = 0.011) compared to the non-catastrophic outcome group. In a binary logistic regression analysis, DWI-ASPECTS (odds ratio [OR], 0.709; 95% confidence interval [CI], 0.524-0.960; p = 0.026) and successful reperfusion (OR, 0.242; 95% CI, 0.071-0.822; p = 0.023) were independent predictors of a catastrophic outcome. Conclusion: Baseline infarct size and reperfusion status were independently associated with a catastrophic outcome after endovascular thrombectomy in elderly patients aged ≥ 80 years with acute anterior circulation LVO.

Background: Sutureless aortic valves may enable shorter procedure times, which benefits patients with elevated surgical risk. We describe the outcomes of patients with aortic stenosis who underwent aortic valve replacement (AVR) using the sutureless Perceval aortic bioprosthesis. Methods: Data from a retrospective cohort were obtained from a clinical database. The study enrolled patients with symptomatic severe aortic stenosis who underwent surgical AVR with a sutureless bioprosthesis between August 2015 and December 2020. In total, 113 patients were included (mean age, 75.3±8.4 years; 57.5% women; median Society of Thoracic Surgeons score, 9.7%; mean follow-up period, 51.19±20.6 months). Of these patients, 41 were octogenarians (36.2%) and 3 were nonagenarians (2.6%). Transthoracic echocardiography was employed to assess changes in ejection fraction (EF), left ventricular mass index (LVMI), and mean pressure gradient (MPG). Results: The in-hospital mortality rate was 2.6%, and 13 patients developed new-onset atrial fibrillation. A permanent pacemaker was implanted in 3 patients (2.6%). The median intensive care unit stay was 1 day (interquartile range [IQR], 1-2 days), and the median hospital stay was 12 days (IQR, 9.5-15 days). The overall survival rate at 5 years was 95.9%. LVMI and MPG were reduced postoperatively, while EF increased over the follow-up period. No structural valve deterioration was observed, and no meaningful paravalvular leakage developed during follow-up. Conclusion: The use of a sutureless valve in the aortic position is safe and feasible, even for high-risk elderly patients requiring surgical AVR. LVMI and MPG decreased postoperatively, while EF increased over the follow-up period.

배경: 평균 수명의 증가에 따른 고령화가 진행되면서 관상동백우회술(CABG)을 시행 받는 환자의 평균연령도 증가하는 경향을 보이고 있다. 고령의 환자에서 심장박동 상태로 시행하는 관상동맥우회술(OPCAB) 은 수술 후 합병증을 줄이고 좋은 임상결과를 보이는 것으로 보고하고 있다. 저자들은 80세 이상의 고령 환자에서 OPCAB을 시행한 중단기 임상 결과를 분석하였다. 대상 및 방법: 2001년 1월부터 2004년 3월까지 심장박동 상태에서 시행하는 관상동맥우회술을 시행 받았던 환자 중 80세 이상의 환자 12명을 대상으로 하다. 대상 환자들의 수술 전 위험요인, 관상동맥질환의 정도 및 수술성적에 대해 조사하였다. 환자들의 평균 연령은 $81.0\pm1.3세(80\~84)$였고, 평균 좌심실 박출계수는 $52.9\pm15.1\% (30\~72)$였다 수술 전 흉통의 정도는 $2.9\pm0.5$였다. 대상 환자 중 11명$(91.7\%)$은 3개 혈관병변, 또는 좌주관상동맥 병변을 보였다. 수술 후 9명의 환자에서 multi-slice 컴퓨터 단층촬영을 시행하여 이식편의 개존율을 조사하였다. 추적은 외래방문 및 전화를 이용하여 조사하였다 걸과: 수술 전 환자들의 위험요소로는 과거력상 뇌경색 4예, 만성 폐쇄성 폐질환 4예 및 급성심근경색이 2예가 있었다. 심근경색 환자 중 1명은 심부전으로 폐부종이 동반되었었다. 환자 당 평균 $2.6\pm0.7$개의 문합을 시행하였다. 수술 후 사망은 없었으며 뇌경색, 심근경색, 신부전증 및 호흡부전증도 없었다. 그러나 1예에서 종격동염이 발생하여 근육 성형술을 시행 받았으며 잘 회복하여 퇴원하였다. 1예에서는 심방세동이 발생하여 약물 치료 후 동율동으로 회복되었다 평균 호흡기 사용시간은 $15.9\pm4.4$시간$(8\~20)$, 중환자실 재원기간은 $2.9\pm0.8일(2\~4)$, 그리고 입원기간은 $21.6\pm14.3일(13\~56)$이었다. 수술 후 평균 CK-MB는 $11.3\pm14.1ng/mL$였다. 수술 후 조기 혈관 개존율은 $100\% (24/24)$였다. 모든 환자에서 완전 추적이 가능하였으며 평균 추적기간은 $20.4\pm15.2개월(5\~43)$이었다. 이 기간 중 사망환자나 흉통이 재발한 환자는 없었다. 걸론: 80세 이상 고령의 환자에서 OPCAB은 수술 후 합병증을 줄이고 좋은 결과를 보여 주었다. 그러므로 고령의 환자에서도 관상동맥우회술의 적응증이 되면 적극적으로 수술을 시행할 필요가 있으며, 수술방법은 OPCAB이 좋을 것으로 생각한다
