Abstract
OBJECTIVES The Magna Ease aortic valve (Edwards Lifesciences, Irvine, CA) is a third-generation bioprosthetic valve developed as a modification of the well-studied Perimount and Magna valve designs. This study's objective is to evaluate a large, single-centre experience with Magna Ease aortic valve replacement (AVR) focusing on clinical outcomes and haemodynamic performance. METHODS All patients undergoing AVR between 8/2010 and 10/2018 at our institution implanted with the Magna Ease valve were included except those undergoing ventricular assist device or congenital aortic surgery. Primary outcomes were overall survival and freedom from reoperation. Mean transprosthetic gradient (mTPG) and structural valve deterioration (SVD) served as secondary outcomes. RESULTS Totally 1126 consecutive implantations of Magna Ease valves were included. Concomitant procedures were performed in 56.5% (n = 636). No severe patient-prosthesis mismatch (PPM) was present at implantation. Overall survival at 30 days, 1 year, 5 years and 9 years was 97.2%, 95.0%, 86.1% and 78.2%, respectively, with improved survival for isolated AVR. Total of 2.4% (n = 27) of patients required reoperation with 0.3% (n = 4) for SVD. Echocardiographic follow-up data revealed low mTPG throughout the study period. SVD occurred in 28.7% of patients at a mean of 3.9 years post implantation. CONCLUSIONS Magna Ease AVR maintained low mean transprosthetic gradients throughout mid-term evaluation and was associated with excellent overall survival and freedom from reoperation at nine years post implantation.

Patient-Prosthesis Mismatch Worsens Long-Term Survival: Insights From the FinnValve Registry. Ann Thorac Surg 2020; 111:1284-1290. [PMID: 32805269 DOI: 10.1016/j.athoracsur.2020.06.026] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 05/22/2020] [Accepted: 06/08/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND The impact of patient-prosthesis mismatch (PPM) on long-term outcome after surgical aortic valve replacement (SAVR) is controversial. We sought to investigate the incidence of PPM and its impact on survival and reinterventions in a Finnish nationwide cohort. METHODS In the context of the nationwide FinnValve registry, we identified 4097 patients who underwent SAVR with a stented bioprosthesis with or without myocardial revascularization. The indexed effective orifice areas (EOAs) of surgical bioprostheses were calculated using literature-derived EOAs. PPM was graded as moderate (EOA 0.65-0.85 cm2/m2) or severe (EOA ≤0.65 cm2/m2). RESULTS The incidence of PPM was 46.0%. PPM was moderate in 38.8% (n = 1579) patients and severe in 7.2% (n = 297) patients. Time-trend analysis showed that the proportion of PPM decreased significantly from 74% in 2009 to 18% in 2017 (P < .01). Severe PPM was associated with increased 5-year all-cause mortality (adjusted hazard ratio [HR], 1.72; 95% confidence interval [CI], 1.07-2.76; P = .02). Severe PPM was not associated with an increased risk of repeat AVR (adjusted HR, 5.90; 95% CI, 0.95-36.5; P = .06). In a subanalysis of patients greater than or equal to 70 years of age, in comparison with no PPM, any PPM (adjusted HR, 1.23; 95% CI, 1.05-1.45; P = .01) and severe PPM (HR, 1.53; 95% CI, 1.17-2.00; P < 0.01) were associated with increased risk of 5-year mortality. CONCLUSIONS Severe PPM after SAVR had a negative impact on survival. This study demonstrated that the effects of PPM should not be overlooked in elderly undergoing SAVR.

Assessment of normal hemodynamic profile of mechanical pulmonary prosthesis by doppler echocardiography: a prospective cross-sectional study. Cardiovasc Ultrasound 2020; 18:14. [PMID: 32414369 PMCID: PMC7229630 DOI: 10.1186/s12947-020-00196-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2020] [Accepted: 05/06/2020] [Indexed: 12/05/2022] Open
Abstract
Objectives Very few reports have described the Doppler-derived echocardiographic parameters for mechanical pulmonary valve prosthesis (MPVP). This study aims to describe the normal Doppler hemodynamic profile of MPVP using Doppler echocardiography. Methods The current prospective, single center observational study enrolled 108 patients who underwent pulmonary valve replacement (PVR) surgery for the first time and had a normally functioning prosthesis post-operation. The hemodynamic performance of MPVPs, considering flow dependent and flow independent parameters, was evaluated at two follow-up points, at week one and week four post-operation. All assessments were conducted by an experienced echocardiographer. Results The mean age (±SD) of the participants was 26.4 (±8.98). Tetralogy of Fallot (ToF) was the most common underlying disease leading to PVR, with a prevalence of 88%. At first week post-operation, measurement of indices reported the following values (±SD): peak pressure gradient (PPG): 18.51(±7.64) mm Hg; mean pressure gradient (MPG): 10.88(±5.62) mm Hg; peak velocity (PV): 1.97(±0.43)m/s; doppler velocity index (DVI): 0.61(±18); pulmonary velocity acceleration time (PVAT): 87.35(±15.16) ms; effective orifice area (EOA): 2.98(±1.02) cm2;and effective orifice area to body surface area ratio (EOA/ BSA): 1.81(±0.62) cm2/m2. Comparing these measurements with those obtained from the second follow-up (at week four post-op) failed to hold significant difference in all values except for PVAT, which had increased from its primary value (p = 0.038). Also, right ventricular (RV) function showed significant improvement throughout the follow up period. Conclusion The findings of this study help strengthen the previously scarce data pool and better establish the normal values for Doppler hemodynamics in mechanical pulmonary prosthesis.

The Fluid Dynamical Performance of the Carpentier-Edwards PERIMOUNT Magna Ease Prosthesis. BIOMED RESEARCH INTERNATIONAL 2018; 2018:5429594. [PMID: 29546062 PMCID: PMC5818907 DOI: 10.1155/2018/5429594] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/23/2017] [Revised: 11/22/2017] [Accepted: 11/28/2017] [Indexed: 12/18/2022]
Abstract
The aim of the present in vitro study was the evaluation of the fluid dynamical performance of the Carpentier-Edwards PERIMOUNT Magna Ease depending on the prosthetic size (21, 23, and 25 mm) and the cardiac output (3.6–6.4 L/min). A self-constructed flow channel in combination with particle image velocimetry (PIV) enabled precise results with high reproducibility, focus on maximal and local peek velocities, strain, and velocity gradients. These flow parameters allow insights into the generation of forces that act on blood cells and the aortic wall. The results showed that the 21 and 23 mm valves have a quite similar performance. Maximal velocities were 3.03 ± 0.1 and 2.87 ± 0.13 m/s; maximal strain Exx, 913.81 ± 173.25 and 896.15 ± 88.16 1/s; maximal velocity gradient Eyx, 1203.14 ± 221.84 1/s and 1200.81 ± 61.83 1/s. The 25 mm size revealed significantly lower values: maximal velocity, 2.47 ± 0.15 m/s; maximal strain Exx, 592.98 ± 155.80 1/s; maximal velocity gradient Eyx, 823.71 ± 38.64 1/s. In summary, the 25 mm Magna Ease was able to create a wider, more homogenous flow with lower peak velocities especially for higher flow rates. Despite the wider flow, the velocity values close to the aortic walls did not exceed the level of the smaller valves.

Abstract
BACKGROUND To evaluate the impact of patient-prosthesis mismatch (PPM) on survival, functional status, and quality of life (QoL) after aortic valve replacement (AVR) with small prosthesis size in elderly patients. METHODS Between January 2005 and December 2013, 152 patients with pure aortic stenosis, aged at least 75 years, underwent AVR, with a 19 or 21 mm prosthetic heart valve. PPM was defined as an indexed effective orifice area less than 0.85 cm/m. Median age was 82 years (range 75-93 years). Mean follow-up was 56 months (range 1-82 months) and was 98% complete. Late survival rate, New York Heart Association functional class, and QoL (RAND SF-36) were assessed. RESULTS Overall, PPM was found in 78 patients (53.8%). Among them, 42 patients (29%) had an indexed effective orifice area less than 0.75 cm/m and 17 less than 0.65 cm/m (11.7%). Overall survival at 5 years was 78 ± 4.5% and was not influenced by PPM (P = NS). The mean New York Heart Association class for long-term survivors with PPM improved from 3.0 to 1.7 (P < 0.001). QoL (physical functioning 45.18 ± 11.35, energy/fatigue 49.36 ± 8.64, emotional well being 58.84 ± 15.44, social functioning 61.29 ± 6.15) was similar to that of no-PPM patients (P = NS). CONCLUSION PPM after AVR does not affect survival, functional status, and QoL in patients aged at least 75 years. Surgical procedures, often time-consuming, contemplated to prevent PPM, may therefore be not justified in this patient subgroup.
