Racial Differences in the Incidence and Impact of Prosthesis-Patient Mismatch After Transcatheter Aortic Valve Replacement. JACC Cardiovasc Interv 2021; 14:2670-2681. [PMID: 34838464 DOI: 10.1016/j.jcin.2021.08.038] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 08/04/2021] [Accepted: 08/17/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVES The aim of this study was to compare the incidence and prognostic significance of prosthesis-patient mismatch (PPM) after transcatheter aortic valve replacement (TAVR) according to racial groups. BACKGROUND PPM after TAVR may be of more concern in Asian populations considering their relatively small annular and valve sizes compared with Western populations. METHODS TP-TAVR (Transpacific TAVR Registry) was an international multicenter cohort study of patients with severe aortic stenosis who underwent TAVR in the United States and South Korea from January 2015 to November 2019. PPM was defined as moderate (0.65-0.85 cm2/m2) or severe (<0.65 cm2/m2) at the indexed effective orifice area. The primary outcome was a composite of death, stroke, or rehospitalization at 1 year. RESULTS Among 1,101 eligible patients (533 Asian and 569 non-Asian), the incidence of PPM was significantly lower in the Asian population (33.6%; moderate, 26.5%; severe, 7.1%) than in the non-Asian population (54.5%; moderate, 29.8%; severe, 24.7%). The 1-year rate of the primary outcome was similar between the PPM and non-PPM groups (27.5% vs 28.1%; P = 0.69); this pattern was consistent between Asian (25.4% vs 25.2%; P = 0.31) and non-Asian (28.7% vs 32.1%; P = 0.97) patients. After multivariable adjustment, the risk for the primary outcome did not significantly differ between the PPM and non-PPM groups in the overall population (HR: 0.95; 95% CI: 0.74-1.21), in Asian patients (HR: 1.07; 95% CI: 0.74-1.55), and in non-Asian patients (HR: 0.86; 95% CI: 0.63-1.19). CONCLUSIONS In this study of patients with severe aortic stenosis who underwent TAVR, the incidence of PPM was significantly lower in Asian patients than in non-Asian patients. The 1-year risk for the primary composite outcome was similar between the PPM and non-PPM groups regardless of racial group. (Transpacific TAVR Registry [TP-TAVR]; NCT03826264).

Abstract
BACKGROUND Tricuspid regurgitation (TR) is a prevalent disease with limited treatment options. OBJECTIVES This is the first 30-day report of the U.S. single-arm, multicenter, prospective CLASP TR early feasibility study of the PASCAL transcatheter valve repair system in the treatment of TR. METHODS Patients with symptomatic TR despite optimal medical therapy, reviewed by the local heart team and central screening committee, were eligible for the study. Data were collected at baseline, discharge, and the 30-day follow-up and were reviewed by an independent clinical events committee and echocardiographic core laboratory. Feasibility endpoints included safety (composite major adverse event [MAE] rate), echocardiographic, clinical, and functional endpoints. RESULTS Of the 34 patients enrolled in the study, the mean age was 76 years, 53% were women, the mean Society of Thoracic Surgeons score was 7.3%, 88% had atrial fibrillation/flutter, 97% had severe or greater TR, and 79% had New York Heart Association (NYHA) functional class III/IV symptoms. Twenty-nine patients (85%) received implants; at 30 days, 85% of them achieved a TR severity reduction of at least 1 grade, with 52% with moderate or less TR (p < 0.001). The MAE rate was 5.9%, and none of the patients experienced cardiovascular mortality, stroke, myocardial infarction, renal complication, or reintervention. Eighty-nine percent of the patients improved to NYHA functional class I/II (p < 0.001), the mean 6-min walk distance improved by 71 m (p < 0.001), and the mean Kansas City Cardiomyopathy Questionnaire score improved by 15 points (p < 0.001). CONCLUSIONS In this early experience, the repair system performed as intended, with substantial TR reduction, favorable safety results with a low MAE rate, no mortality or reintervention, and significant improvements in functional status, exercise capacity, and quality of life.

Abstract
OBJECTIVES The study reports for the first time the 30-day outcomes of the first U.S. study with the Cardioband tricuspid valve reconstruction system for the treatment of functional tricuspid regurgitation (TR). BACKGROUND Increasing severity of TR is associated with progressively higher morbidity and mortality; however, treatment options for isolated significant disease are limited. METHODS In this single-arm, multicenter, prospective Food and Drug Administration-approved early feasibility study (EFS), 30 patients with severe or greater symptomatic functional TR were enrolled who were deemed candidates for transcatheter tricuspid repair with the Cardioband tricuspid system by the local heart team and multidisciplinary screening committee. RESULTS The mean patient age was 77 years, 80% were women, 97% had atrial fibrillation, 70% were in New York Heart Association functional class III to IV with mean left ventricular ejection fraction of 58%, and 27% had severe, 20% massive, and 53% torrential TR. Device success was 93% and all patients were alive at 30 days. Between baseline and 30 days, septolateral tricuspid annular diameter was reduced by 13% (p < 0.001), 85% of patients had ≥1 grade TR reduction and 44% had ≤moderate TR, 75% were in New York Heart Association functional class I to II (p < 0.001), and overall Kansas City Cardiomyopathy Questionnaire score improved by 16 points (p < 0.001). CONCLUSIONS In patients with severe symptomatic functional TR, this is the first study in the United States with the Cardioband tricuspid system for direct transcatheter annular reduction. This early feasibility study demonstrates high procedural feasibility with no 30-day mortality. There is significant reduction of functional TR with clinically significant improvements in functional status and quality of life.

Abstract
IMPORTANCE More than 40 million people are living with either mitral or aortic valve disease worldwide, and more than 180 000 heart valve replacement surgeries are performed each year in the US. Transcatheter valve repair has emerged as an important therapeutic option for patients who are candidates for heart valve replacement. OBSERVATIONS All transcatheter valve therapies involve a multidisciplinary team of interventional cardiologists, cardiothoracic surgeons, radiologists, echocardiographers, nurses, and social workers, termed the heart team, to determine the optimal approach for managing each patient. Transcatheter aortic valve implantation (TAVI) is an aortic valve replacement procedure that is performed percutaneously and is currently approved for patients with severe, symptomatic aortic stenosis in all surgical risk categories. The TAVI procedure can be performed using a balloon-expandable or self-expanding valve. In a low-risk cohort of patients (PARTNER [Placement of Aortic Transcatheter Valves] 3 trial), the rates of death from any cause, stroke, or rehospitalization were 8.5% for patients receiving TAVI and 15.1% for patients undergoing surgical aortic valve replacement. Decision-making regarding therapy choice should be based on individual anatomy (including the number of leaflets, annular size, and peripheral arterial anatomy), comorbidities (including concomitant coronary artery disease and aortopathies), and patient preference guide. A mitral transcatheter edge-to-edge repair device is approved by the US Food and Drug Administration for high-risk patients with degenerative and functional mitral regurgitation that has excellent safety and efficacy in these populations. In the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial, the annualized rate of all hospitalizations for heart failure was 35.8% among patients who underwent transcatheter edge-to-edge repair and received medical therapy compared with 67.9% among patients in the medical therapy alone group. Transcatheter tricuspid valve repair and replacement trials are ongoing and show promise for the treatment of patients with tricuspid regurgitation, which previously had limited therapeutic options. Multimodality imaging, which includes transthoracic echocardiography, transesophageal echocardiography, computed tomography, and intracardiac echocardiography, is important for preprocedural planning, device selection, and optimal outcomes. CONCLUSIONS AND RELEVANCE Approximately 78 000 TAVI procedures and 10 000 transcatheter mitral valve repairs take place yearly in the US to treat patients with severe, symptomatic aortic stenosis and mitral regurgitation, respectively. Transcatheter valve therapies have expanded therapeutic options for patients, including for those who previously had no viable surgical options.

Abstract
OBJECTIVES To assess the outcomes following transcatheter edge-to-edge mitral valve repair (TMVr) in patients with chronic kidney disease (CKD). BACKGROUND Percutaneous TMVr is beneficial in high surgical risk patients with severe mitral regurgitation (MR). However, those with CKD are not well studied. METHODS Utilizing the International Classification of Disease (ninth and tenth revision, clinical modification codes) and the Nationwide Inpatient Sample database, we identified 9,228 patients who underwent TMVr during 2010-2016, including those with no or mild CKD (group 1, n = 6,654 [72.11%]), moderate or severe CKD (group 2, n = 2,125 [23.03%]) and end-stage renal disease (ESRD) on dialysis (group 3, n = 449 [4.86%]). In-hospital clinical outcomes, length of stay and cost were assessed. RESULTS In-hospital mortality increased numerically as CKD severity increased, but not statistically different between groups (1.8, 3.3, and 4.5% respectively in group 1, 2, and 3, p = .07). Moderate to severe CKD (group 2) was an independent predictor of acute renal failure requiring hemodialysis (ARFD) (OR: 3.51, CI: 2.33-5.28, p < .0001), the composite outcome of death, ARFD or stroke [OR: 3.15, 95% CI: 2.10-4.76, p < .0001] and extended length of stay [OR: 1.73, 95% CI: 1.24-2.42), p = .001] while ESRD (group 3) was an independent predictor of higher hospital cost [OR: 1.66, 95% CI: 1.01-2.74), p = .04] as compared with no or mild CKD (group 1). CONCLUSIONS High surgical risk patients with severe MR commonly have associated comorbidities including CKD. TMVr outcomes appear to worsen with worsening CKD and therefore careful clinical case selection and further studies evaluating TMVr outcomes in CKD patients is warranted.

Abstract
OBJECTIVES We investigated the durability of tricuspid regurgitation (TR) reduction and the clinical outcomes through 12 months after transcatheter tricuspid valve repair (TTVr) with the PASCAL Transcatheter Valve Repair System. BACKGROUND TTVr has rapidly developed and demonstrated favorable acute outcomes, but longer follow-up data are needed. METHODS Overall, 30 patients (age 77 ± 6 years; 57% female) received PASCAL implantation from September 2017 to May 2019 and completed a clinical follow-up at 12 months. RESULTS The TR etiology was functional in 25 patients (83%), degenerative in three (10%), and mixed in two (7%). All patients had TR severe or greater (massive or torrential in 80%) and heart failure symptoms (90% in NYHA III or IV) under optimal medical treatment. Single-leaflet device attachment occurred in two patients. Moderate or less TR was achieved in 23/28 patients (82%) at 30 days, which was sustained at 12 months (86%). Two patients underwent repeat TTVr due to residual torrential TR (day 173) and recurrence of severe TR (day 280), respectively. One-year survival rate was 93%; 6 patients required rehospitalization due to acute heart failure. NYHA functional class I or II was achieved in 90% and 6-minute walk distance improved from 275 ± 122 m at baseline to 347 ± 112 m at 12-month (+72 ± 82 m, p < .01). There was no stroke, endocarditis, or device embolization during the follow-up. CONCLUSIONS Twelve-month outcomes from this multicenter compassionate use experience with the PASCAL System demonstrated high procedural success, acceptable safety, and significant clinical improvement.

Abstract
OBJECTIVE Surgical reoperation for aortic homograft structural valve degeneration (SVD) is a high-risk procedure. Transcatheter aortic valve replacement (TAVR) for homograft-SVD is an alternative to reoperation, but descriptions of implantation techniques are limited. This study compares outcome in patients undergoing into two groups by the type of previously implanted aortic valve prosthesis: TAVR for failed aortic homografts (TAVR-H) or for stented aortic bioprostheses (TAVR-BP). METHODS From 2015 to 2017, TAVR was performed in 41 patients with SVD. Thirty-three patients in the TAVR-BP group (six for SVD of valved conduits), and eight patients in the TAVR-H group. The Valve Academic Research Consortium criteria were used for outcome reporting purposes. RESULTS The patients with TAVR-BP had predominant prosthetic stenosis (94%, p = .002), whereas TAVR-H individuals presented mostly with regurgitation (88%, p = <.001). Patients with TAVR-H received: Sapien-3 (6), Sapien-XT (1), and CoreValve (1) devices. Low, 40% ventricular fixation in relation to homograft annulus was attempted to anchor the prosthesis on the homograft suture-line. One patient with TAVR-BP experienced intraoperative distal prosthesis migration and Type-B aortic dissection, and two patients in the TAVR-H group had late postoperative proximal device migration. In both groups, there was zero 30-day mortality, stroke, or pacemaker implantation. CONCLUSIONS TAVR for failing aortic homografts may be a feasible and safe alternative to high-risk surgical reintervention. Precise, 40%-ventricular device positioning appears crucial for prevention of late paravalvular leak/late prosthesis migration and minimizing the risk of repeat surgical intervention.

Abstract
To evaluate k-t accelerated 3D cine b-SSFP (balanced steady state free precession) as magnetic resonance imaging (MRI) technique for aortic annular area measurement in transcatheter aortic valve replacement (TAVR) planning compared to computed tomography angiography (CTA) and other non-contrast MRI sequences with reduced imaging time and without contrast administration. 6 volunteers and 7 TAVR candidates were prospectively enrolled. The volunteers underwent an MRI while TAVR candidates underwent an MRI and CTA. The following non-contrast MRI sequences were obtained at the level of the aortic root: 2D cine b-SSFP [GRAPPA (GeneRalized Autocalibrating Partially Parallel Acquisitions), R = 2], 3D cine b-SSFP [GRAPPA R = 2], navigator triggered 3D b-SSFP MRA [GRAPPA, R = 2] and k-t accelerated 3D cine b-SSFP [PEAK GRAPPA, R = 5]. Qualitative analysis and aortic annular area measurements in systole and diastole were obtained. k-t accelerated 3D cine b-SSFP provided image quality that is acceptable for confident diagnosis with very good interrater agreement. There was no statistically significant difference in aortic annular measurements between k-t accelerated 3D cine b-SSFP and CTA or other MRI sequences (p > 0.05). Bland-Altman analysis showed no systemic difference of annular area measurements between k-t accelerated 3D cine b-SSFP and each of the other techniques. There was excellent inter-rater agreement on aortic annular area measurements during systolic (ICC = 0.976, p < 0.001) and diastolic (ICC = 0.971, p < 0.001) phases using k-t accelerated 3D cine b-SSFP. K-t accelerated 3D cine b-SSFP is a promising alternative for the assessment of annular sizing in pre-TAVR evaluation while offering a reasonable combination of imaging parameters during one breath-hold.

Abstract
The use of LDT may signify significant hemodynamic changes and left ventricular remodeling in severe aortic stenosis (AS). Therefore, we sought to determine whether loop diuretic therapy (LDT) is associated with adverse outcomes following transcatheter aortic valve implantation (TAVI) in patients with severe symptomatic AS. Subjects undergoing TAVI at a single institution from June 2008 to December 2017 were analyzed. LDT doses were normalized to oral furosemide daily equivalents. All outcomes were adjudicated using VARC2 criteria. Descriptive statistics, multivariate logistic regression, and propensity score matching were used. Of the 804 subjects studied, 48.3% were on pre-TAVI LDT with a mean dose of 51.1 mg furosemide dose-equivalents. Subjects on LDT were higher risk, frail patients with more co-morbidities including chronic kidney disease, coronary artery disease requiring prior bypass grafting, peripheral arterial disease, atrial fibrillation or flutter, and diabetes with more severe heart failure symptoms. Those on LDT also had worse left ventricular systolic function, lower transvalvular gradients, and markers of adverse left ventricular remodeling, including increased left ventricular mass index and higher rates of concentric and eccentric hypertrophy. On propensity-score matching, death within one year post-TAVI was borderline significantly higher in the pre-LDT as compared with no-LDT group (16.9% vs 10.4 %, p = 0.068). In conclusion, use of pre-TAVI LDT for severe symptomatic AS is associated with a trend towards worse 1-year mortality and is a marker of high-risk, frail individuals with advanced left ventricular remodeling.

Abstract
Tricuspid valve (TV) degeneration after surgical repair with an annuloplasty ring is problematic as redo operation carries high mortality. This can be addressed with transcatheter therapies to implant a valve within in prior ring (tricuspid valve-in-ring). When an incomplete ring is present, paravalvular leak is commonly encountered after tricuspid valve-in-ring (TViR) implant; however, this can be addressed with paravalvular leak closure devices. Multimodality imaging including cardiac computed tomography and three-dimensional (3D) transesophageal echocardiography (TEE) are important for successful TViR implant. We report a case of tricuspid regurgitation after tricuspid repair with an incomplete annuloplasty ring and subsequent paravalvular leak closure.

Abstract
AIMS Chronic total occlusion (CTO) has been linked to worse survival. While controversial and limited to observational data, successful CTO percutaneous coronary intervention (PCI) has been associated with improved left ventricular (LV) function and mortality. However, the role of CTO PCI prior to transcatheter aortic valve replacement (TAVR) is not clear. We sought to explore the prognostic impact of a pre-TAVR CTO on post-TAVR outcomes. METHODS AND RESULTS We retrospectively reviewed 783 consecutive TAVR cases performed at a single tertiary care medical center. Pre-TAVR angiograms were analyzed for the presence of a CTO. At the time of TAVR, 12.6% (n = 99) patients had a CTO. At one-year post-TAVR, there was no significant association between the presence of a CTO and death (14.2% vs 13.1%, p = 0.75), functional status, quality of life, or adverse events. There was also no difference in long-term survival (4.1 years vs 4.1 years, p = 0.55). LV ejection fraction was lower in the CTO group at baseline and one year (p < 0.01). CONCLUSIONS The presence of a CTO did not have any prognostic impact on mortality, change in LV function, or improvement in functional status and angina scores following TAVR in our cohort of elderly, high-risk patients. CTO before TAVR was associated with decreased ejection fraction at baseline and at one year.

Abstract
Objective Transcatheter aortic valve replacement is a safe, minimally invasive treatment for severe aortic stenosis in patients with moderate-to-high surgical risk. Monitored anesthesia is administered by an anesthesiologist. This study compares transcatheter aortic valve outcomes under monitored anesthesia vs general anesthesia. Methods Data were prospectively collected for 286 patients undergoing transcatheter aortic valve replacement at a single academic hospital from March 2012 to August 2016. The patients were grouped by type of anesthesia: monitored vs general. A propensity score match was performed to compare intraoperative and post-operative outcomes between groups. Results General anesthesia was used in 102 patients and moderate sedation in 184. Propensity score matching produced 80 pairs. Compared to procedures under general anesthesia, patients receiving monitored anesthesia had shorter procedure (1.6 [1.4, 2.0] vs 2.0 [1.6, 2.5] hours; P < 0.001) and fluoroscopy times (17 [14.5, 22.5] vs 25 [17.9, 30.3] minutes; P < 0.001) and shorter hospital length-of-stay (3 [2.0, 4.0] vs 5 [3.0, 7.0] days; P < 0.001) but no difference in intensive care unit length-of-stay. Blood transfusion was more common in patients undergoing general anesthesia, but there was no difference in stroke, renal failure, postoperative atrial fibrillation, or need for permanent pacemaker. More patients were discharged to home after monitored anesthesia (90% vs 64%; P < 0.001). There was no difference in 30-day mortality (0% vs 3%; P = 0.15). Conclusions Transcatheter aortic valve replacement under monitored anesthesia provides the safety of anesthesia-led sedation without intubation and general anesthetic. We found no compromise in patient safety or clinical outcomes.

Abstract
The optimal revascularization strategy for CAD in the TAVR population is not well-defined and decisions about which patients require PCI have been largely operator dependent or based on SYNTAX score. In a TAVR population, complete revascularization does not improve short or long term mortality, but is associated with decreased acute myocardial infarction and revascularization, when compared with incomplete revascularization. Future prospective studies should evaluate revascularization strategies in TAVR patients, including considering functional lesion assessment with fractional flow reserve, especially as TAVR indications are likely to soon expand to a younger and healthier cohort.

Abstract
There are multiple proposed mechanisms for the pathophysiology of heart failure (HF) with preserved ejection fraction (HFpEF). We hypothesized that coronary microvascular dysfunction is common in these patients. In a prospective, observational study, patients undergoing cardiac catheterization with HFpEF [left ventricular (LV) ejection fraction ≥ 50% and with clinical HF] were compared with similar patients without HFpEF. Patients with ≥50% stenosis were excluded, and coronary flow reserve (CFR) and the index of microvascular resistance (IMR) were measured after adenosine administration using a guidewire, with CFR ≤ 2 and IMR ≥ 23 being abnormal. Baseline characteristics and CFR and IMR were compared in 30 HFpEF patients and 14 control subjects. Compared with control subjects, HFpEF patients were older (65.4 ± 9.6 vs. 55.1 ± 3.1 yr, P < 0.01), had higher numbers of comorbidities (4.4 ± 1.5 vs. 2.6 ± 1.9, P = 0.002), had higher median B-type natriuretic peptide [161 (interquartile range: 75-511) pg/dl vs. 37 (interquartile range: 18.5-111) pg/dl, P < 0.01], and had higher LV end-diastolic pressure (17.8 ± 4.2 vs. 8.4 ± 4.2, P < 0.01). HFpEF patients had lower CFR (2.55 ± 1.60 vs. 3.84 ± 1.89, P = 0.024) and higher IMR (26.7 ± 10.3 vs. 19.7 ± 9.7 units, P = 0.037) than control subjects. Most (71.4%) control subjects had normal coronary physiology, whereas 36.7% of HFpEF patients had both abnormal CFR and IMR and another 36.7% had either abnormal CFR or IMR. In conclusion, this is the first study that has reported invasively determined CFR and IMR in HFpEF patients. We demonstrated the presence of four distinct coronary physiology groups in HFpEF patients. Investigation into the potential mechanisms for these findings is needed. NEW & NOTEWORTHY In this prospective observational study of patients with heart failure with preserved ejection fraction (HFpEF), we found that patients with HFpEF had more abnormalities of coronary flow and resistance than asymptomatic control patients, indicating that coronary microvascular dysfunction may play a role in the HFpEF disease process.

Abstract
We report the case of a 55‐year‐old woman with heart failure with preserved ejection fraction (HFpEF), who presented with hypertensive urgency and pulmonary oedema. The patient was medically optimized and underwent cardiac catheterization revealing pulmonary hypertension, elevated pulmonary capillary wedge pressure, normal cardiac index, and non‐obstructive coronary disease. Invasive evaluation of coronary flow revealed blunted coronary flow reserve and increased index of microvascular resistance. Cardiac magnetic resonance imaging demonstrated reduced global myocardial perfusion and diffuse interstitial fibrosis. This case exhibits a potential HFpEF phenotype associated with microvascular dysfunction, fibrosis, and elevated filling pressures.

Abstract
Statin therapy is associated with improved survival in patients at high risk for cardiovascular mortality, but the impact of statin therapy in patients treated with transcatheter aortic valve replacement (TAVR) is unknown. We reviewed 294 consecutive cases of TAVR performed at a single tertiary care medical center. We defined high-intensity statin therapy as atorvastatin 40 to 80 mg/day or rosuvastatin 20 to 40 mg/day. Study outcomes included post-TAVR adverse events, 30-day mortality, and overall survival. At the time of TAVR, 14% (n = 41) were on high-intensity statin therapy, 59% (n = 173) were on low- or moderate-intensity statin therapy, and 27% (n = 80) were not on statin therapy. There was no association between statin therapy and the rate of post-TAVR stroke, myocardial infarction, acute kidney injury, in-hospital mortality, or 30-day mortality. At 2 years, 83% of patients in the high-intensity statin group were alive, 70% in the low/moderate-intensity statin group were alive, and 57% in the no statin group were alive (log-rank p = 0.016). In a risk-adjusted model, high-intensity statin therapy was associated with a 64% reduction in all-cause mortality (hazard ratio 0.36, 95% CI 0.14 to 0.90, p = 0.029) compared with no statin therapy. In conclusion, statin therapy is associated with improved overall survival after TAVR in a dose-dependent manner.

Abstract
BACKGROUND Little is known about baseline diastolic dysfunction and changes in diastolic dysfunction grade after transcatheter aortic valve replacement (TAVR) for aortic stenosis (AS) and its impact on overall outcomes. The aim of this study was to describe baseline diastolic dysfunction and changes in diastolic dysfunction grade that occur with TAVR and their relationship to mortality and rehospitalization. METHODS This was a single-center study evaluating all TAVRs from January 2012 to June 2014. We compared parameters of diastolic dysfunction grade on pre-TAVR and 1 month post-TAVR echocardiograms for all patients undergoing the procedure. Descriptive statistics, Kaplan-Meier time-to-event analysis, and multivariate logistic regression were used. RESULTS Of a sample size of 120 patients undergoing TAVR for symptomatic severe AS, 90 were included in the final analysis after excluding significant mitral valve disease. There were improvements in individual parameters of diastolic dysfunction grade such as lateral e' velocity, E/lateral e', and left atrial volume index (nonsignificant trend) in the setting of improvement in aortic valve area and gradients and functional class pre- and post-TAVR. Multivariate analysis revealed that baseline diastolic dysfunction grade, but not post-TAVR or changes in diastolic dysfunction grade, was associated with 1-year death (hazard ratio, 1.163; 95% CI, 1.049-1.277, P = .005) and combined death/cardiovascular hospitalization (hazard ratio, 1.174; 95% CI, 1.032-1.318; P = .018). CONCLUSIONS In this single-center retrospective study of patients with symptomatic severe AS who underwent TAVR, several diastolic function parameters improved on echocardiography, but baseline diastolic dysfunction grade remained the most important echocardiographic factor associated with adverse 1-year outcomes.
