Abstract
The St. Jude Medical Epic Supra valve is a porcine bioprosthesis designed for complete supraannular implantation. No report has shown the hemodynamic performance and clinical outcomes of aortic valve replacement with the Epic Supra valve for severe aortic stenosis in a Japanese cohort. We retrospectively evaluated 65 patients who underwent aortic valve replacement using the Epic Supra valve for aortic stenosis at our department between May, 2011 and October, 2016. The mean follow-up period was 68.7 ± 32.7 months, and the follow-up rate was 89.2%. The mean age was 76.8 ± 5.3 years. The 1-, 5-, and 8-year survival rates were 96.9%, 79.4%, and 60.3%, respectively. The rates of freedom from valve-related events were 96.6% and 81.9% at 5 and 8 years, respectively. Four patients were diagnosed with structural valve deterioration (SVD), and reintervention was performed in two patients. The rates of freedom from SVD were 98.2% and 83.3% at 5 and 8 years, respectively, and the mean time to diagnosis of SVD was 72.5 ± 25.3 months. The mean pressure gradient (MPG) was 16.8 ± 6.0 mmHg postoperatively, 17.5 ± 9.4 mmHg at 5 years, and 21.2 ± 12.4 mmHg at 8 years (p = 0.08). The effective orifice area index (EOAI) was 0.95 ± 0.2 cm2/m2 immediately after surgery, 0.96 ± 0.27 cm2/m2 at 5 years, and 0.84 ± 0.2 cm2/m2 at 8 years (p = 0.10). An increase in MPG and decrease in EOAI were also observed, which may be associated with SVD. Follow-up after 5 years is important to determine if there is an increase.

Abstract
Transcatheter aortic valve implantation (TAVI) is an increasingly popular treatment option for patients with severe aortic stenosis. Recent advancements in technology and imaging tools have significantly contributed to the success of TAVI procedures. Echocardiography plays a pivotal role in the evaluation of TAVI patients, both before and after the procedure. This review aims to provide an overview of the most recent technical advancements in echocardiography and their use in the follow-up of TAVI patients. In particular, the focus will be on the examination of the influence of TAVI on left and right ventricular function, which is frequently accompanied by other structural and functional alterations. Echocardiography has proven to be key also in detecting valve deterioration during extended follow-up. This review will provide valuable insights into the technical advancements in echocardiography and their role in the follow-up of TAVI patients.

J Clin Med 2022; 11:jcm11247482. [PMID: 36556098 PMCID: PMC9783780 DOI: 10.3390/jcm11247482] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 12/09/2022] [Accepted: 12/12/2022] [Indexed: 12/23/2022] Open
Abstract
Patient-prosthesis mismatch (PPM) causes a high transvalvular pressure gradient and residual left ventricular (LV) hypertrophy, consequently influencing long-term results. This study aimed to find the relationships between hemodynamic parameters and LV mass regression and determine the risk predictors of major adverse cardiovascular and cerebral events (MACCE) after aortic valve replacement (AVR) for aortic stenosis. Methods and Results: Preoperative and postoperative Doppler echocardiography data were evaluated for 120 patients after AVR. The patients' mean age was 67.7 years; 55% of the patients were male. Forty-four (37%) patients suffered from MACCE during a mean follow-up period of 3.6 ± 2 years. The following hemodynamic parameters at follow-up were associated with lower relative indexed LV mass (LVMI) regression: lower postoperative indexed effective orifice area, greater mean transvalvular pressure gradient (MPG), greater stroke work loss (SWL), and concentric or eccentric LV remodeling mode. The following hemodynamic parameters at follow-up were associated with a higher risk of MACCE: higher valvuloarterial impedance (ZVA), greater SWL, greater MPG, greater relative wall thickness, greater LVMI, and hypertrophic LV remodeling mode. Lower relative LVMI regression was associated with a higher risk of MACCE (hazard ratio, 1.01: 95% confidence interval, 1.003-1.03). The corresponding cutoff of relative LVMI regression was -14%. Conclusions: Changes in hemodynamic parameters were independently associated with relative LVMI regression. Impaired reverse remodeling and persistent residual LV hypertrophy were independent risk predictors of MACCE. An LVMI regression lower than 14% indicated higher MACCE. A postoperative ZVA greater than 3.5 mmHg/mL/m2 was an independent risk predictor of cardiac events and mortality after AVR. Preventive strategies should be used at the time of the operation to avoid PPM.

Abstract
A virtual workshop was organized by the Heart Valve Collaboratory to identify areas of expert consensus, areas of disagreement, and evidence gaps related to bioprosthetic aortic valve hemodynamics. Impaired functional performance of bioprosthetic aortic valve replacement is associated with adverse patient outcomes; however, this assessment is complicated by the lack of standardization for labelling, definitions, and measurement techniques, both after surgical and transcatheter valve replacement. Echocardiography remains the standard assessment methodology because of its ease of performance, widespread availability, ability to do serial measurements over time, and correlation with outcomes. Management of a high gradient after replacement requires integration of the patient's clinical status, physical examination, and multimodality imaging in addition to shared patient decisions regarding treatment options. Future priorities that are underway include efforts to standardize prosthesis sizing and labelling for both surgical and transcatheter valves as well as trials to characterize the consequences of adverse hemodynamics.

Diastolic Function and Clinical Outcomes After Transcatheter Aortic Valve Replacement: PARTNER 2 SAPIEN 3 Registry. J Am Coll Cardiol 2021; 76:2940-2951. [PMID: 33334422 DOI: 10.1016/j.jacc.2020.10.032] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 09/29/2020] [Accepted: 10/19/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND Few studies have evaluated if diastolic function could predict outcomes in patients with aortic stenosis. OBJECTIVES The authors aimed to assess the association between diastolic dysfunction (DD) and outcomes in patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). METHODS Baseline, 30-day, and 1- and 2-year transthoracic echocardiograms from the PARTNER (Placement of Aortic Transcatheter Valves) 2 SAPIEN 3 registry were analyzed by a consortium of core laboratories and divided into the American Society of Echocardiography DD groups. RESULTS Among the 1,750 included, 682 (54.4%) had grade 1 DD, 352 (28.1%) had grade 2 DD, 168 (13.4%) had grade 3 DD, and 51 (4.1%) had indeterminate DD grade. Incremental baseline grades of DD were associated with an increase in combined 1- and 2-year cardiovascular (CV) death/rehospitalization (all p < 0.002) and all-cause death at 2 years (p = 0.01) but not at 1 year. Improvement in DD grade/grade 1 DD at 30 days post-TAVR was seen in 70.8% patients. Patients with improvement in ≥1 grade of DD/grade 1 DD had reduced 1-year CV death/rehospitalization (p < 0.001) and increased 2-year survival (p = 0.01). Baseline grade 3 DD was a predictor of 1-year CV death/rehospitalization (hazard ratio: 2.73; 95% confidence interval: 1.07 to 6.98; p = 0.04). Improvement in DD grade/grade 1 DD at 30 days was protective for 1-year CV death/rehospitalizations (hazard ratio: 0.39; 95% confidence interval: 0.19 to 0.83; p = 0.01). CONCLUSIONS In the PARTNER 2 SAPIEN 3 registry, baseline DD was a predictor of up to 2 years clinical outcomes in patients who underwent TAVR. Improvement in DD grade at 30 days was associated with improvement in short-term clinical outcomes.

Abstract
BACKGROUND Impairment in left ventricular (LV) systolic strain in aortic stenosis (AS) is well documented. However, alterations in layer-specific LV global longitudinal strain (GLS) and global circumferential strain (GCS) and their recovery following surgical aortic valve replacement (AVR) have not been established. The aim of this study was to examine layer-specific changes in GLS and GCS in patients with AS undergoing AVR and compare these patients with those managed conservatively over 12 months. METHODS Eighty-six patients (mean age, 68.8 ± 12 years; 60 men) with AS (19 mild, 15 moderate, and 52 severe) were prospectively recruited. Patients with coronary disease or other significant valvular disease were excluded. Forty patients (46.5%) with severe AS underwent AVR. All patients underwent baseline echocardiography. Patients managed conservatively underwent follow-up echocardiography at 12 months. Patients undergoing AVR underwent follow-up echocardiography at 1 week and 3, 6, and 12 months after AVR. RESULTS There was worsening in subendocardial but not subepicardial or transmural GLS even in mild AS (-20.9 ± 1.0% vs -20.6 ± 0.8%, P = .012). In moderate AS, worsening in subendocardial (-19.6 ± 0.9% vs -18.2 ± 1.5%, P = .003), subepicardial (-14.9 ± 1.0% vs -13.8 ± 1.2%, P = .004), and transmural (-17.1 ± 0.9% vs -15.8 ± 1.3%, P = .03) GLS and a trend toward significant worsening in subendocardial GCS (-29.8 ± 5.16% vs -27.5 ± 5%, P = .054) were seen. Conservatively managed patients with severe AS had significant worsening in subendocardial (-16.1 ± 1.6% vs -13.9 ± 2.6%, P = .021), subepicardial (-11.6 ± 1.1% vs -10.1 ± 2.1%, P = .027), and transmural (-13.6 ± 1.3% vs -11.8 ± 2.3%, P = .02) GLS and subendocardial (-24.9 ± 3.6% vs -20.8 ± 4.5%, P = .002) and transmural (-16.9 ± 1.7% vs -14.3 ± 3.5%, P = .04) GCS on follow-up. Patients after AVR demonstrated significant improvement in GLS (from 3 months) and GCS (from 6 months) in both myocardial layers. CONCLUSIONS Patients with AS managed conservatively had worsening of GLS over 12 months despite preserved LV ejection fraction, detected earliest in the subendocardial layer. GCS became progressively impaired in moderate and severe AS. Improvement in LV strain after AVR was seen earlier with GLS (from 3 months) than with GCS (from 6 months) in both myocardial layers.

Abstract
OBJECTIVE Patient-prosthesis mismatch (PPM) may affect clinical outcomes in patients with aortic valve replacement (AVR). We retrospectively examined the PPM in patients with isolated AVR in the Japan Adult Cardiovascular Surgery Database (JACVSD). METHODS We examined all patients with isolated AVR between January 1, 2008 and December 31, 2009. The JACVSD data collection form has a total of 255 variables. We defined PPM as an effective orifice area index of ≤ 0.85 m(2)/cm(2). RESULTS PPM was observed in 306 of 3,609 cases analyzed, PPM rate was 8.5 %. Body surface area was larger and body mass index was higher in the PPM group than the non-PPM group (P < 0.001). Patients with PPM were older (P = 0.001) and had a higher prevalence of diabetes (P = 0.004), dyslipidemia (P < 0.001), hypertension (P < 0.001), cerebrovascular disease (P = 0.031), old myocardial infarction (P = 0.006), previous percutaneous coronary artery intervention (P = 0.001), coronary artery disease (P = 0.018), and aortic valve stenosis (P < 0.001). Perioperative blood transfusion (P < 0.001) and dialysis (P = 0.005) were more frequent in the PPM group. Postoperative ventilation (P = 0.004) and intensive care unit stay (P = 0.004) were significantly longer in the PPM group. CONCLUSIONS Age, aortic valve stenosis, dyslipidemia, hypertension, old myocardial infarction, previous percutaneous coronary artery intervention, diabetes mellitus, cerebrovascular disease, and high body mass index were the risk factors for PPM. PPM was not an independent risk factor for short-term mortality.

Magnetic resonance imaging versus echocardiography to ascertain the regression of left ventricular hypertrophy after bioprosthetic aortic valve replacement: results of the REST study. J Thorac Cardiovasc Surg 2011; 144:640-645.e1.

Abstract
OBJECTIVES To compare the decrease in left ventricular mass index (LVMI) by magnetic resonance imaging (MRI) versus transthoracic echocardiography (TTE) after aortic valve replacement (AVR) for severe aortic stenosis with Epic and Epic Supra stented porcine bioprostheses (St Jude Medical, Inc, St Paul, Minn). METHODS This prospective multicenter study enrolled 149 patients who underwent AVR between January 2006 and February 2008. TTE and cardiac MRI measurements of LVMI were made at baseline and at 6 months of follow-up and were compared. Changes in mean pressure gradients were examined using TTE. RESULTS TTE measurements of LVMI were 48% to 63% higher than the MRI measurements. A decrease in LVMI from 137 ± 32 to 95 ± 16 g/m(2) with the Epic and from 139 ± 29 to 104 ± 28 g/m(2) with the Epic Supra valves (P < .0001 for both comparisons) was measured by TTE. Cardiac MRI revealed decreases in LVMI from 84 ± 20 to 64 ± 12 g/m(2) and from 86 ± 27 to 64 ± 17 g/m(2) with the Epic and Epic Supra valves, respectively (P < .0001 for both comparisons). TTE revealed a significant regression of mean pressure gradients from 51.6 ± 15.3 to 15.5 ± 5.2 mm Hg with the Epic and from 46.7 ± 19.4 to 17.9 ± 12.8 mm Hg with the Epic supra (P < .0001 for both comparisons). CONCLUSIONS A significant decrease in LVMI was measured after AVR with all sizes of both bioprosthetic models. Because of the overestimation of the decrease in LVMI by the Devereux formula, as well as the higher accuracy and reproducibility of cardiac MRI measurements, the latter should be preferred to TTE. An ultimate validation of this thesis could only be done comparing each of these modalities with pathologic examination.
