A 16-Year Experience in Minimally Invasive Aortic Valve Replacement

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.

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.

The Impact

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.
