- Abstract
Background: Increased left ventricular (LV) afterload in patients with aortic stenosis consists of valvular and vascular loads; however, the effects of vascular load induced by arterial stiffness on clinical outcomes after transcatheter aortic valve replacement (TAVR) remain unclear. This study evaluated the prognostic value of brachial-ankle pulse wave velocity (baPWV) after TAVR., Methods: A retrospective study including 161 consecutive patients who underwent TAVR with a pre-procedural baPWV assessment was conducted. We investigated the association between baPWV and the 1-year composite outcome comprising all-cause death and rehospitalization related to heart failure. Echocardiographic measurements including the LV mass index (LVMi) and LV diastolic function at 1, 6, and 12 months after TAVR were assessed., Results: Of the 161 patients, 31 patients experienced composite outcome within 1 year after TAVR. The receiver operating characteristic curve analysis revealed that the discriminating baPWV level to discern 1-year composite outcome was 1,639 cm/s, and all subjects were allocated to two groups based on the result. Baseline characteristics were comparable between the high baPWV (n = 72) and low baPWV groups (n = 89). The Kaplan-Meier curve revealed a significantly higher cumulative 1-year composite outcome in the high baPWV group than in the low baPWV group (31% vs. 10%; log-rank test, p<0.001). High baPWV was an independent predictor of the 1-year composite outcome (adjusted hazard ratio, 3.42; 95% confidence interval, 1.62-7.85; p = 0.002). Furthermore, post-procedural echocardiography revealed that the high baPWV group had less LVMi regression and higher E/e' after TAVR compared to the low baPWV group. The delayed reversal in LVMi and diastolic function attributable to arterial stiffness might be linked to impaired clinical outcomes after TAVR., Conclusions: Higher baPWV could be associated with adverse clinical outcomes and delayed reverse LV remodeling after TAVR., (Copyright © 2021.

- Abstract
Severe aortic stenosis (AS) is considered as an independent risk factor for perioperative cardiac complications of non-cardiac surgery. Surgical aortic valve replacement should be considered before non-cardiac surgery in patients with symptomatic severe AS. However, recently, transcatheter aortic valve replacement (TAVR) has emerged as an alternative approach for selected AS patients. We sought to determine the safety and efficacy of TAVR in preparation for major non-cardiac surgery. From our retrospective database, seven patients who underwent TAVR in preparation for major non-cardiac surgery were identified, and their clinical and hemodynamic data were collected. After TAVR, a significant reduction in the mean transaortic pressure gradient from 54.0 (Interquartile range (IQR) 47.5-64.5) to 18.0 (IQR 12.5-19.0) mmHg (p = 0.016) and an increase in the calculated aortic valve area from 0.6 (IQR 0.6-0.7) to 1.3 (IQR 1.1-1.5) cm
2 (p = 0.022) were noted. Non-cardiac surgery included lung segmentectomy and lymph node dissection, lung lobectomy, ileocecal resection, partial colectomy, partial nephrectomy, nephroureterectomy, laparoscopic nephrectomy, and laparoscopic nephroureterectomy. All the initial non-cardiac surgeries were performed without cardiac complications, under general anesthesia, 37 (IQR 32-74) days after TAVR. Two of the patients eventually needed additional non-cardiac surgery, which was performed uneventfully without the need for additional AS treatment. TAVR was an effective and safe procedure that might reduce the risk of general anesthesia and major non-cardiac surgery in severe AS.- Published

- Abstract
Background: Objective nutritional indexes have been shown to predict prognoses in some clinical settings. We aimed to investigate the prognostic values of these indexes in patients undergoing transcatheter aortic valve implantation (TAVI)., Methods: We retrospectively analyzed 95 consecutive patients who underwent TAVI at our institution from December 2013 to February 2017. As objective nutritional indexes, a controlling nutritional status (CONUT) score, prognostic nutritional index (PNI), and geriatric nutritional risk index (GNRI) were calculated at baseline. The optimal cut-off values were determined using receiver operating characteristic curve analysis. According to the cut-off values, we investigated the association of these indexes with 1-year clinical outcomes including all-cause mortality and re-hospitalization due to heart failure., Results: In the Kaplan-Meier analysis, patients with a higher CONUT score and lower PNI had significantly higher incidence rates of 1-year mortality (26.9% vs. 2.9%; p<0.001, 17.4% vs. 2.0%; p=0.011, respectively) and composite outcome of mortality and re-hospitalization due to heart failure (38.5% vs. 13.0%; p=0.006, 39.3% vs. 11.9%; p=0.002, respectively). On Cox hazard analysis, CONUT score and PNI were significantly associated with 1-year mortality [hazard ratio (HR): 1.91; 95% confidence interval (CI): 1.27-2.88; p=0.002, HR: 0.86; 95% CI: 0.75-0.99; p=0.031, respectively] and the composite outcome (HR: 1.49; 95% CI: 1.11-2.00; p=0.007, HR: 0.88; 95% CI: 0.80-0.97; p=0.011, respectively)., Conclusions: The CONUT score and PNI are associated with 1-year clinical outcomes especially with 1-year all-cause mortality in patients undergoing TAVI. Moreover, the CONUT score and PNI might have better predictive values than GNRI., (Copyright © 2019. Published by Elsevier Ltd.)

- Abstract
Background: Obesity has previously been identified as an indicator of good prognosis in patients undergoing transcatheter aortic valve implantation (TAVI), an association known as the "obesity paradox". We investigated whether abdominal total fat area (TFA), visceral fat area (VFA), or subcutaneous fat area (SFA) are prognostic indicators of long-term clinical outcome in patients undergoing TAVI., Methods and results: We retrospectively analyzed 100 consecutive patients who underwent TAVI between December 2013 and April 2017. TFA, VFA, and SFA were measured from routine pre-procedural computed tomography (CT). Patients were divided into 2 groups according to median TFA, VFA, or SFA, and we investigated the association of abdominal fat area with adverse clinical events, including all-cause death and re-hospitalization due to worsening heart failure. At a median follow-up of 665 days, patients with higher SFA had significantly lower incidence of the composite outcome and all-cause death compared with patients with lower SFA (15.0% vs. 37.7%, P=0.025; and 8.9% vs. 23.7%, P=0.047, respectively). In contrast, patients with higher TFA or VFA did not show significant reduction in the incidences of the composite outcome or all-cause mortality., Conclusions: CT-derived SFA had prognostic value in patients undergoing TAVI.

- Abstract
This report describes an elderly severe aortic stenosis (AS) patient, who had a history of coronary artery bypass grafting and endovascular repair for an abdominal aortic aneurysm (AAA). Type II endoleak with enlargement of AAA was diagnosed and ligation of inferior mesenteric artery (IMA) was recommended. Because aortic valve replacement (AVR) was high risk, we planned transcatheter aortic valve implantation (TAVI). Considering risks of IMA ligation under dual antiplatelet therapy, increased blood pressure after TAVI, and general anesthesia, we performed combined TAVI and IMA ligation. TAVI could be useful for AS patients who are at high risk for AVR before non-cardiac surgery.
