Abstract 3172: Impact of Prosthesis-Patient Mismatch on Long-Term Survival After Aortic Valve Replacement

Background: We recently reported that Prosthesis-Patient Mismatch (PPM) is an independent predictor of operative mortality in patients undergoing aortic valve replacement (AVR). The objective of this study was to evaluate the impact of PPM on late postoperative survival. Methods and Results: Between 1992 and 2005, 2653 patients (age: 68±10 years; 61% of males) underwent AVR in our institution. Patients who died at the time of operation or within 30 days were excluded from this study. The projected indexed effective orifice area (EOAi) was derived from the published normal in vivo EOA values for each model and size of prosthesis and PPM was classified as severe if the EOAi was ≤0.65 cm 2 /m 2 , moderate if it was > 0.65 cm 2 /m 2 and ≤ 0.85 cm 2 /m 2 , or not clinically significant if >0.85 cm 2 /m 2 . PPM was severe in 40 patients (2%), moderate in 797 (31%), and not significant in 1739 (67%). Patients with severe PPM had higher proportion of female gender (67% vs. 38%; P=0.0002) and hypertension (68% vs. 55%, p=0.02) and larger body surface (1.86±0.25 vs. 1.77±0.20, p=0.02). For patients with severe PPM, 5-year survival rate (74±8%) and 10-year survival rate (40±10%) were significantly (p=0.008) less than for patients with moderate PPM (5-yr: 81±2% and 10-yr: 57±3%) or no significant PPM (5-yr: 84±1% and 10-yr: 61±2%). On multivariate analysis after adjustment for other predictors of outcome, severe PPM was associated with increased overall mortality (Hazard ratio 1.38, [95% Confidence Interval 1.04 –1.75]; (p=0.02) Conclusion: In our previous study, we reported that severe PPM is a powerful risk factor for operative mortality. The results of the present study now suggest that severe PPM is also an independent predictor of long-term mortality. Hence, for the patients who are identified to be at risk of severe PPM at the time of operation, every effort should be made to implant a prosthesis with a larger EOA.

Long Term Mortality

Introduction Atrial fibrillation (AF) is frequent after any cardiac surgery, but evidence suggests it may have no significant impact on survival if sinus rhythm (SR) is effectively restored early after the onset of the arrhythmia. In contrast, management of preoperative AF is often overlooked during or after cardiac surgery despite several proposed protocols. This study sought to evaluate the impact of preoperative AF on mortality in patients undergoing isolated surgical aortic valve replacement (AVR). Methods We performed a retrospective, single-centre study involving 2,628 consecutive patients undergoing elective, primary isolated surgical AVR from 2008 to 2018. A total of 268/ 2,628 patients (10.1%) exhibited AF before surgery. The effect of preoperative AF on mortality was evaluated with univariate and multivariate analyses. Results Short-term mortality was 0.8% and was not different between preoperative AF and SR cohorts. Preoperative AF was highly predictive of long-term mortality (median follow-up of 4 years [Q1-Q3 2-7]; HR: 2.24, 95% CI: 1.79-2.79, P<0.001), and remained strongly and independently predictive after adjustment for other risk factors (HR: 1.54, 95% CI: 1.21-1.96, P<0.001) compared with preoperative SR. In propensity score-matched analysis, the adjusted mortality risk was higher in the AF cohort (OR: 1.47, 95% CI: 1.04-1.99, P=0.03) compared with the SR cohort. Conclusions Preoperative AF was independently predictive of long-term mortality in patients undergoing isolated surgical AVR. It remains to be seen whether concomitant surgery or other preoperative measures to correct AF may impact long-term survival.

Objective The aim of this study was to evaluate short- and long-term morbidity and mortality in patients with aortic valve disease who had minimally invasive aortic valve replacement (AVR) through upper hemisternotomy. Methods From July 1996 to June 2012, a total of 1639 patients underwent minimally invasive aortic valve surgery (AVR). Patient data were extracted from hospital electronic records after institutional review board approval. Outcomes of interest included postoperative complication rates, perioperative mortality, and long-term survival. Results The mean age was 67 years (SD, 14 years; range, 22–95 years). Of the total cohort, 211 (13%) underwent reoperative AVR. Postoperatively, 2.3% (37/1639) had reoperations to correct bleeding, 2.7% (44/1639) had strokes, 20.4% (334/1639) had new-onset atrial fibrillation, and 1.5% (24/1639) required permanent pacemakers. Only 34% (571/1639) of the patients received packed red blood cells. The median discharge was on day 6 (5–8), and 72.2% of the patients (1184/1639) were discharged home. Operative mortality was 2.9% (48/1639), and long-term survival at 1, 5, 10, and 15 years was 96%, 93%, 92%, and 92%, respectively. Operative mortality was 5.7% (12/208) for the reoperative patients. Conclusions The upper hemisternotomy approach for AVR is safe and reliable, especially for patients undergoing reoperations and those older than 80 years.

Risk Patients

Background: Younger patients with severe symptomatic aortic stenosis are a particularly challenging collective with regard to the choice of intervention. High-risk patients younger than 75 years of age are often eligible for both the transcatheter aortic valve replacement (TAVR) and the isolated surgical aortic valve replacement (iSAVR). Data on the outcomes of both interventions in this set of patients are scarce. Methods: One hundred and forty-four propensity score-matched patients aged 75 years or less who underwent TAVR or iSAVR at the Hietzing Heart Center in Vienna, Austria, were included in the study. The mean age was 68.9 years (TAVR 68.7 vs. SAVR 67.6 years; p = 0.190) and the average EuroSCORE II was 5.4% (TAVR 4.3 [3.2%] vs. iSAVR 6.4 (4.3%); p = 0.194). Results: Postprocedural adverse event data showed higher rates of newly acquired atrial fibrillation (6.9% vs. 19.4%; p = 0.049), prolonged ventilation (2.8% vs. 25.0%; p < 0.001) and multi-organ failure (0% vs. 6.9%) in the surgical cohort. The in-hospital and 30-day mortality was significantly higher for iSAVR (1.4% vs. 13.9%; p = 0.012; 12.5% vs. 2.8%; p = 0.009, respectively). The long-term survival (median follow-up 5.0 years (2.2–14.1 years)) of patients treated with the surgical approach was superior to that of patients undergoing TAVR (p < 0.001). Conclusion: Although the survival analysis revealed a higher in-hospital and 30-day survival rate for high-risk patients aged ≤75 years who underwent TAVR, iSAVR was associated with a significantly higher long-term survival rate.

The Impact

Abstract Background The impact of patient-prosthesis mismatch (PPM) after aortic valve replacement (AVR) on long-term survival and quality of life (QoL) remains controversial. The objective of this study was to evaluate the impact of PPM on long-term survival and QoL in a large cohort of patients treated with isolated stented biological AVR in a single-center experience. Methods We analyzed data of 632 consecutive patients following isolated stented biological AVR between 2007 and 2012 at our institution. We evaluated the QoL (393 evaluable patients) using the Short Form 12-item Health Survey (SF-12) questionnaire via telephone call and the impact of PPM on long-term survival (533 evaluable patients) by Kaplan–Meier's estimate. Results Severe PPM (<0.65 cm2/m2) had a negative impact on physical component summary (PCS) score (SF-12) compared with patients with moderate or no PPM (p = 0.014), while the mental component summary (MCS) score (SF-12) was not affected by the degree of PPM (p = 0.133). Long-term survival was not different among the three different PPM groups investigated (p = 0.75). Conclusion Severity of PPM demonstrated no influence on long-term survival and MCS score (SF-12), but it was associated with a lower PCS score (SF-12) in patients with severe PPM.

Abstract Background This study describes the long-term survival, risk of reoperation and clinical outcomes of patients undergoing solitary surgical aortic valve replacement (SAVR) with a Carpentier-Edwards Perimount (CE-P) bioprosthetic in Western Denmark. The renewed interest in SAVR is based on the questioning regarding the long-term survival since new aortic replacement technique such as transcatheter aortic-valve replacement (TAVR) probably have shorter durability, why assessment of long-term survival could be a key issue for patients. Methods From November 1999 to November 2013 a cohort of a total of 1604 patients with a median age of 73 years (IQR: 69–78) undergoing solitary SAVR with CE-P in Western Denmark was obtained November 2018 from the Western Danish Heart Registry (WDHR). The primary endpoint was long-term survival from all-cause mortality. Secondary endpoints were survival free from major adverse cardiovascular and cerebral events (MACCE), risk of reoperation, cause of late death, patient-prothesis mismatch, risk of AMI, stroke, pacemaker or ICD implantation and postoperative atrial fibrillation (POAF). Time-to-event analysis was performed with Kaplan-Meier curve, cumulative incidence function was performed with Nelson-Aalen cumulative hazard estimates. Cox regression was applied to detect risk factors for death and reoperation. Results In-hospital mortality was 2.7% and 30-day mortality at 3.4%. The 5-, 10- and 15-year survival from all-cause mortality was 77, 52 and 24%, respectively. Survival without MACCE was 80% after 10 years. Significant risk factors of mortality were small valves, smoking and EuroSCORE II ≥4%. The risk of reoperation was < 5% after 7.5 years and significant risk factors were valve prosthesis-patient mismatch and EuroSCORE II ≥4%. Conclusions Patients undergoing aortic valve replacement with a Carpentier-Edwards Perimount valve shows a very satisfying long-term survival. Future research should aim to investigate biological valves long-term durability for comparison of different SAVR to different TAVR in long perspective.

Long Term Survival

Aortic valve replacement for aortic stenosis represents one of the most frequent surgical procedures on heart valves. These patients often have concomitant mitral regurgitation. To reveal whether the moderate mitral regurgitation will improve after aortic valve replacement alone, we performed a systematic review and meta-analysis. We identified 27 studies with 4452 patients that underwent aortic valve replacement for aortic stenosis and had co-existent mitral regurgitation. Primary end point was the impact of aortic valve replacement on the concomitant mitral regurgitation. Secondary end points were the analysis of the left ventricle reverse remodeling and long-term survival. Our results showed that there was significant improvement in mitral regurgitation postoperatively (RR, 1.65; 95% CI 1.36–2.00; p < 0.00001) with the average decrease of 0.46 (WMD; 95% CI 0.35–0.57; p < 0.00001). The effect is more pronounced in the elderly population. Perioperative mortality was higher (p < 0.0001) and long-term survival significantly worse (p < 0.00001) in patients that had moderate/severe mitral regurgitation preoperatively. We conclude that after aortic valve replacement alone there are fair chances but for only slight improvement in concomitant mitral regurgitation. The secondary moderate mitral regurgitation should be addressed at the time of aortic valve replacement. A more conservative approach should be followed for elderly and high-risk patients.
