Survival and quality of life after surgical aortic valve replacement in octogenarians

The Influence of Preoperative Physical Activity on Intraoperative Brain Function in Cardiac Surgical patients

Background Preoperative physical activity and intraoperative brain health are recognized to influence postoperative delirium (POD). Electroencephalogram (EEG) burst suppression and cerebral desaturation are indicators of abnormal intraoperative brain health. Our study aimed to investigate the associations between preoperative physical activity and intraoperative EEG burst suppression and cerebral desaturation. Methods We retrospectively analyzed data from 67 patients from one of the institutions participating in a multisite randomized controlled trial, PANDORA, involving patients undergoing cardiac surgery. The preoperative PCS12 score calculated using the SF12 questionnaire was used as an indicator of preoperative physical activity. Intraoperative EEG and cerebral oximetry data (not the current standard of care in this facility) were collected, and the anesthesiologists were blinded to the information. We analyzed the following associations between the PCS12 score and i) burst suppression duration, ii) the number of cerebral desaturations, and iii) the number of observations with concurrent cerebral desaturation and burst suppression using a generalized linear model. The results are presented as percentage changes in outcomes, and a 95% C.I. p value < 0.05 was considered to indicate statistical significance. Results Each unit increase in the PCS12 score was associated with a 3.3% decrease in the duration of burst suppression (-3.3 [-5.3, -1.2], p value = 0.002). The duration of burst suppression decreased by 29.2% with each successive quartile increase in the PCS-12 score, indicating a dose‒response relationship (-29.2 [-41.6, -16], p < 0.001). Specifically, the patients in the last three quartiles exhibited a 55.4% reduction in BSD compared to those in the first quartile (-55.4 [-74.4, -24.6], p = 0.002) (Fig. 2). We did not observe any significant association between the PCS12 score and cerebral desaturation. Conclusion Decreased preoperative physical activity, as measured by the SF-12 questionnaire, is significantly associated with increased EEG burst suppression duration. Preoperative physical activity did not show any association with cerebral desaturations and concurrent cerebral desaturation and burst suppression.

Surgical aortic valve replacement in octogenarians: Single-center perioperative outcomes and five-year survival

INTRODUCTION AND OBJECTIVES

Aortic stenosis is the most common valvular heart disease. The number of octogenarians proposed for intervention is growing due to increased lifespan. In this manuscript we aim to evaluate perioperative outcome and long-term survival after surgical aortic valve replacement (SAVR) in octogenarians, comparing patients with low surgical risk (EuroscoreII <4%) with intermediate-high risk (EuroscoreII ≥4%).

METHODS

A retrospective observational single-center cohort study with 195 patients aged ≥80 years old, who underwent SAVR between 2017 and 2021, was conducted. Patients were divided into two groups according to EuroscoreII: (1) Low risk (EuroscoreII <4%) with intermediate-high risk (EuroscoreII ≥4%). Continuous variables are presented in median (IQR), analyzed using Wilcoxon rank sum test; categorical variables in percentages, analyzed using chi-squared test; and survival was analyzed by Kaplan-Meier, open cohort, and the log-rank test was performed.

RESULTS

The overall median age was 82 (IQR 81-83), with 4.6% of the patients ≥85 years old. 23.6% of the patients presented EuroscoreII ≥4%. No complications were observed in 26.2%, with a significantly higher rate in intermediate-high risk patients. Postoperative need for hemodynamic support was the most frequent complication, followed by postoperative acute kidney injury and the use of blood products. Overall median ICU stay was three days (2-4) and hospital length of stay (LOS) six days (5-8). Patients with intermediate-high risk and those with complications had longer ICU LOS. At 12 months, overall survival was 96.4%, at three years 94.1% and 5 years 75.4%. Patients with low surgical risk had higher survival proportions up to 5 years.

CONCLUSION

SAVR in patients ≥80 years is associated with low in-hospital mortality, although a significant proportion of patients develop complications. Long-term follow-up up to five years after surgery is acceptable in octogenarians with low surgical risk.

Quality of Life Measures in Aortic Stenosis Research: A Narrative Review

BACKGROUND

Elderly patients with aortic stenosis (AS) not only have a reduced life expectancy but also a reduced quality of life (QoL). The benefits of an AS intervention may be considered a balance between a good QoL and a reasonably extended life. However, the different questionnaires being used to determine the QoL were generally not developed for the specific situation of patients with AS and come with strengths and considerable weaknesses. The objective of this article was to provide an overview of the available QoL instruments in AS research, describe their strengths and weaknesses, and provide our assessment of the utility of the available scoring instruments for QoL measurements in AS.

SUMMARY

We identified and reviewed the following instruments that are used in AS research: Short Form Health Survey (SF-36/SF-12), EuroQol-5D (EQ-5D), the Illness Intrusiveness Rating Scale (IIRS), the HeartQoL, the Kansas City Cardiomyopathy Questionnaire (KCCQ), the Minnesota Living with Heart Failure Questionnaire (MLHF), the MacNew Questionnaire, and the Toronto Aortic Stenosis Quality of Life Questionnaire (TASQ).

KEY MESSAGES

There is no standardized assessment of QoL in patients with AS. Many different questionnaires are being used, but they are rarely specific for AS. There is a need for AS-specific research into the QoL of patients as life prolongation may compete for an improved QoL in this elderly patient group.

Surgical versus transcatheter aortic valve replacement: Impact of patient-prosthesis mismatch on outcomes

BACKGROUND

The hemodynamics of most prosthetic valves are often inferior to that of the normal native valve, and a significant proportion of patients undergoing surgical (SAVR) or transcatheter aortic valve replacement (TAVR) have high residual transaortic pressure gradients due to prosthesis-patient mismatch (PPM). As the experience with TAVR has increased and long-term outcomes are reported, a close look at the PPM literature is required in light of new evidence.

METHODS

For this review, we searched the Embase, Medline, and Cochrane databases from 2000 to 2022. Articles reporting PPM as an outcome following aortic valve replacements were identified and reviewed.

RESULTS

The impact of PPM on clinical outcomes in aortic valve replacement has not been clear as multiple studies failed to report PPM incidence. However, the PPM outcomes after SAVR vary more widely than after TAVR, ranging from 8% to 80% in SAVR and from 24% to 35% in TAVR. Incidence of severe PPM following redo SAVR ranges from 2% to 9% and following valve-in-valve TAVR is from 14% to 33%, however, while PPM is higher in valve-in-valve TAVR, patients had better survival rates.

CONCLUSIONS

The gap between valve performance and clinical outcomes in SAVR and TAVR could be reduced by carefully selecting patients for either treatment option. Understanding predictors of PPM can add to the safety, effectiveness, and increased survival benefit of both SAVR and TAVR.

Evaluating treatment-specific post-discharge quality-of-life and cost-effectiveness of TAVR and SAVR: Current practice & future directions

•

Post-TAVR HRQOL shows more rapid short-term improvement than SAVR within trials.

•

Higher TAVR use requires better real-world TAVR/SAVR cost-effectiveness comparisons.

•

Wearable devices should be used in real-world settings to compare TAVR/SAVR HRQOL.

Background

Aortic stenosis is a prevalent valvular heart disease that is treated primarily by surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR), which are common treatments for addressing symptoms secondary to valvular heart disease. This narrative review article focuses on the existing literature comparing recovery and cost-effectiveness for SAVR and TAVR.

Methods

Major databases were searched for relevant literature discussing HRQOL and cost-effectiveness of TAVR and SAVR. We also searched for studies analyzing the use of wearable devices to monitor post-discharge recovery patterns.

Results

The literature focusing on quality-of-life following TAVR and SAVR has been limited primarily to single-center observational studies and randomized controlled trials. Studies focused on TAVR report consistent and rapid improvement relative to baseline status. Common HRQOL instruments (SF-36, EQ-5D, KCCQ, MLHFQ) have been used to document that TF-TAVR is advantageous over SAVR at 1-month follow-up, with the benefits leveling off following 1 year. TF-TAVR is economically favorable relative to SAVR, with estimated incremental cost-effectiveness ratio values ranging from $50,000 to $63,000/QALY gained. TA-TAVR has not been reported to be advantageous from an HRQOL or cost-effectiveness perspective.

Conclusions

While real-world experiences are less described, large-scale trials have advanced our understanding of recovery and cost-effectiveness of aortic valve replacement treatment strategies. Future work should focus on scalable wearable device technology, such as smartwatches and heart-rate monitors, to facilitate real-world evaluation of TAVR and SAVR to support clinical decision-making and outcomes ascertainment.

Mid-term clinical and health-related quality of life outcomes for the Trifecta bioprosthesis

Background

The Trifecta valve has been reported to have excellent hemodynamics. Controversy exists on occurrence of patient-prosthesis mismatch (PPM) and data on mid-term outcome is sparse. Health-related quality of life (HRQoL) assessment for the Trifecta valve has not been reported before. The aim of this study was to report the mid-term clinical and HRQoL outcomes in patients undergoing Trifecta valve implantation at our institution.

Methods

In this prospective, observational study, patients undergoing an aortic valve replacement (AVR) using the Trifecta valve were included. Data collection was retrospective from prospectively collected institutional database. Clinical and echocardiographic data were collected prospectively during follow-up. Quality of life was assessed using the Short Form-36 (SF-36) questionnaire.

Results

Forty-seven patients were included in the study of which 9 (19%) were women. Isolated AVR was carried out in 33 (70%) patients. In-hospital mortality and 30-day mortality were 1 (2.1%) and 2 (4.2%), respectively. With a mean indexed effective orifice area (iEOA) 0.96 ± 0.1, none of the patients had severe PPM. Moderate PPM was seen in 19%. The mean follow-up was 3 ± 1.7 years. The 5-year survival estimate was 83.2% in the overall cohort, 81.4% in the isolated and 87.5% in the concomitant procedure group. Freedom from re-operation and structural valve degeneration at 5 years was 95.7% and 97.8%. The mean physical health composite was 69.24 ± 2 and the mean mental health composite was 69.7 ± 25, indicating excellent mental and physical well-being among patients.

Conclusion

The Trifecta valve provides satisfactory hemodynamics, survival and freedom from re-operation and excellent HRQoL at mid-term follow-up.

Surgical Aortic Valve Replacement in the Elderly: It Is Worth It!

To evaluate survival and quality of life of octogenarians after surgical aortic valve replacement (SAVR), up to 10 year of follow-up. Retrospective observational study on octogenarians operated for an isolated or combined SAVR in 2 centers between 2005 and 2011. Preoperative data were collected for each patient and updated regularly with last follow-up on July 2018. Early postoperative course was assessed for all patients. The primary outcome was late survival after discharge. Health-related quality of life was evaluated in all surviving patients using the Short-Form 12 questionnaire. Nine hundred and nine patients were included. The median age was 82 ± 2.6 years, with 400/909 females (44%). Isolated AVR was performed in 452/909 patients (49.7%). Early in-hospital mortality occurred in 71/909 patients (7.8%). Mean follow-up was 5.9 ± 3.4 years. Survival at 2, 5, and 10 years in the overall cohort was 89%, 70%, and 28%, respectively, without significant difference between isolated or combined AVR. Survival was significantly higher in patients with a Euroscore <8% (P< 0.0001). Multivariate analysis found that older age at surgery, diabetes, history of myocardial infarction, atrial fibrillation and chronic renal failure were predictors of long-term mortality. Finally, the SF-12 physical score was 40.7 ± 10.4 and mental and emotional score was 52.7 ± 8.6 at last follow-up, which falls within the expected range for the general population (50 ± 10) with comparable age. SAVR remains an effective treatment for aortic valve disease in octogenarians, not only increasing life expectancy but also conferring a long-standing quality of life with excellent valve durability.

Effect of Cardiac Surgery on Health-Related Quality of Life in Patients Aged 75 Years or Older: A Prospective Study

BACKGROUND

Health-related quality of life (HRQoL) of patients, aged 75 years or older, was measured before and at 12 weeks after cardiac surgery using a generic tool (SF12 version 2).

METHODS

This was a single centre, prospective study of patients aged 75 years or older who had any type of cardiac surgery. The instrument was self-administered preoperatively and by interviewer administered via telephone at 12 weeks.

RESULTS

Sixty-six (66) of the 81 participants approached were eligible and agreed to participate. Mean age was 79.2 years, 17 participants were female (25.8%), 56 participants were New Zealand European (84.8%) and the mean Euroscore II score was 4.0. Sixty (60) participants (90.9%) provided data at follow-up. All mean HRQoL domain scores significantly improved by 12 weeks after surgery. The pattern of gain was similar for ages 75-79 and 80 years and older. The changes in the physical and mental component summary (PCS, MCS) scores were statistically significant and the mean scores were proximate to or better than age group norms at 12 weeks. The number of patients with a PCS score at or above age group norms improved from 16.4% to 56.6% while the number of patients whose MCS scores were at or above age group norms improved from 55.7% to 81.6%. Health utility values also significantly improved.

CONCLUSIONS

Cardiac surgery in older patients is associated with significantly improved physical and mental health-related quality of life at 12 weeks after procedure.

The impact of surgical aortic valve replacement on quality of life-a multicenter study

OBJECTIVES

To explore the effect of surgical aortic valve replacement on quality of life and the variance with age, particularly in patients at risk of deterioration.

METHODS

In an observational, multicenter, cohort study of routinely collected health data, patients undergoing and electively operated between January 2011 and January 2015 with pre- and postoperative quality of life data were included. Patients were classified into 3 age groups: <65, 65-79, and ≥80 years. Quality of life was measured at baseline and at 1-year follow-up using the Short-Form Health Survey-12 or SF-36. We defined a >5-point difference as a minimal clinically important difference. Multivariable linear regression analysis, with adjustment for confounders, was used to evaluate the association between age and quality of life.

RESULTS

In 899 patients, mean physical health increased from 55 to 66 and mental health from 60 to 66. A minimal clinically important decreased physical health was observed in 12% of patients aged <65 years, 16% of patients aged 65-79 years, and 22% of patients aged ≥80 years (P = .023). A decreased mental health was observed in 15% of patients aged <65 years, 22% of patients aged 65-79 years, and 24% aged ≥80 years (P = .030). Older age and a greater physical and mental score at baseline were associated with a decreased physical and mental quality of life (P < .001).

CONCLUSIONS

Patients surviving surgical aortic valve replacement on average improve in physical and mental quality of life; nonetheless, with increasing age patients are at higher risk of experiencing a deterioration.

Does additional coronary artery bypass grafting to aortic valve replacement in elderly patients affect the early and long-term outcome?

Early and long-term outcomes in elderly patients who underwent isolated aortic valve replacement (iAVR) are well defined. Conflicting data exist in elderly patients who underwent AVR plus coronary artery bypass grafting (CABG). We sought to evaluate the early and long-term outcomes of combined AVR + CABG in patients older than 75 years of age. From June 1999 to June 2018, 402 patients ≥ 75 years who underwent iAVR (n = 200; 49.7%) or combined AVR plus CABG (n = 202; 50.3%) were retrospectively analysed. AVR + CABG patients were older than iAVR patients (78.5 ± 2.5 vs 77.6 ± 2.8 years; p < 0.0001), with greater co-morbidities and more urgent/emergency surgery. 30-day mortality was 6.5% in the AVR + CABG and 4.5% in the iAVR group (p = 0.38). Multivariate analysis identified EuroSCORE II [odd ratio (OR) 1.13] postoperative stroke (OR 12.53), postoperative low cardiac output syndrome (OR 8.72) and postoperative mechanical ventilation > 48 h (OR 8.92) as independent predictors of 30-day mortality; preoperative cerebrovascular events (OR 3.43), creatinine (OR 7.27) and extracorporeal circulation time (OR 1.01) were independent predictors of in-hospital major adverse cardiovascular and cerebral events (MACCE). Treatment was not an independent predictor of 30-day mortality and in-hospital MACCE. Survival at 1, 5 and 10 years was 94.7 ± 1.6%, 72.6 ± 3.6% and 31.7 ± 4.8% for iAVR patients and 89.1 ± 2.3%, 73.9 ± 3.5% and 37.2 ± 4.8% for AVR + CABG subjects (p = 0.99). Using adjusted Cox regression model, creatinine [hazard ration (HR) 1.50; p = 0.018], COPD (HR 1.97; p = 0.003) and NYHA class (HR 1.39; p < 0.0001) were independent predictors of late mortality; the combined AVR + CABG was not associated with increased risk of late mortality (HR 0.83; p = 0.30). In patients aged ≥ 75 years, combined AVR + CABG was not associated with increased 30-day mortality, in-hospital MACCE and long-term mortality. Surgical revascularization can be safely undertaken at the time of AVR in elderly patients.

Delirium Incidence and Functional Outcomes After Transcatheter and Surgical Aortic Valve Replacement

BACKGROUND

Transcatheter aortic valve replacement (TAVR) may be associated with less delirium and allow faster recovery than surgical aortic valve replacement (SAVR).

OBJECTIVE

To examine the association of delirium and its severity with clinical and functional outcomes after SAVR and TAVR.

DESIGN

Prospective cohort study.

SETTING

An academic medical center.

PARTICIPANTS

A total of 187 patients, aged 70 years and older, undergoing SAVR (N = 77) and TAVR (N = 110) in 2014 to 2016.

MEASUREMENTS

Delirium was assessed daily using the Confusion Assessment Method (CAM), with severity measured by the CAM-Severity (CAM-S) score (range = 0-19). Outcomes were prolonged hospitalization (9 days or more); institutional discharge; and functional status, measured by ability to perform 22 daily activities and physical tasks over 12 months.

RESULTS

SAVR patients had a higher incidence of delirium than TAVR patients (50.7% vs 25.5%; P < .001), despite younger mean age (77.9 vs 83.7 years) and higher baseline Mini-Mental State Examination score (26.9 vs 24.7). SAVR patients with delirium had a shorter duration (2.2 vs 3.4 days; P = .04) with a lower mean CAM-S score (4.5 vs 5.7; P = .01) than TAVR patients with delirium. The risk of prolonged hospitalization in no, mild, and severe delirium was 18.4%, 30.8%, and 61.5% after SAVR (P for trend = .009) and 26.8%, 38.5%, and 73.3% after TAVR (P for trend = .001), respectively. The risk of institutional discharge was 42.1%, 58.3%, and 84.6% after SAVR (P for trend = .01) and 32.5%, 69.2%, and 80.0% after TAVR (P for trend <.001), respectively. Severe delirium was associated with delayed functional recovery after SAVR and persistent functional impairment after TAVR at 12 months.

CONCLUSION

Less invasive TAVR was associated with lower incidence of delirium than SAVR. Once delirium developed, TAVR patients had more severe delirium and worse functional status trajectory than SAVR patients did.

Preoperative determinants of quality of life a year after coronary artery bypass grafting: a historical cohort study

Background

Health related quality of life (HRQL) is an important patient related outcome measure after cardiac surgery. Preoperative determinants for postoperative HRQL have not yet been identified, but could aid in preoperative decision making. The aim of this article is to identify associations between preoperative determinants and change in HRQL 1 year after coronary artery bypass grafting (CABG).

Methods

Single centre retrospective cohort study in 658 patients. Change in HRQL was defined as a decrease or increase of ≥5 points on the physical or mental domain of the Short Form 12 (SF-12) questionnaire. Patients were stratified in three groups according to worse, unchanged, or better HRQL. Multinomial logistic regression analysis was used to investigate the association between preoperative risk factors and postoperative change in HRQL.

Results

Physical HRQL improved in 22.8% of patients, did not change in 61.2% of patients and worsened in 16.0% of patients. Comorbidities associated with change in physical HRQL were a history of stroke, atrial fibrillation, vascular disease or pulmonary disease. Most important risk factor for change in physical HRQL was preoperative HRQL. Higher preoperative SF-12 score decreased the odds for worse physical HRQL and increased the odds for better physical HRQL. Mental HRQL improved in 49.8% of patients, remained unchanged in 34.5% of patients and worsened in 15.7% of patients. Preoperative HRQL was an important risk factor for a change in mental HRQL. Higher preoperative physical HRQL increased the odds for improved mental HRQL. Lower preoperative mental HRQL increased the odds for better mental HRQL.

Conclusions

One year after CABG the majority of patients experiences equal or improved HRQL compared to before surgery. Most important preoperative risk factor for change in HRQL is preoperative HRQL.

Functional capacity and health-related quality of life outcomes post transcatheter aortic valve replacement: a systematic review and meta-analysis

Background

transcatheter aortic valve replacement (TAVR) provides prognostic benefit for high surgical-risk patients with severe aortic stenosis (AS), yet the impact to patient outcomes is far less understood.

Method

we performed a systematic review and meta-analysis to evaluate functional capacity and health-related quality of life (HRQoL) outcomes for patients up to 12 months post TAVR. A total of 20 eligible publications, comprising randomised-controlled trials, observational studies and a registry study were identified from electronic databases, including MEDLINE, EMBASE, Cochrane Library and others (inception to February 2017).

Results

the total sample was 2,775 with a mean age of 81.8 ± 2.1 years, more than half (52%) were female and high surgical risk 9.6 ± 4.3% mean STS (Society of Thoracic Surgeons risk model). Post TAVR, patients had significant improvement in functional capacity of >40 m in the 6-minute walk test (6MWT) (95% confidence interval (CI) 9.69-73.28) and a clinically meaningful increase in ability to perform daily physical-based tasks (Duke Activity Status Index (DASI), mean difference (MD) increase 5.42 points, 95% CI 3.16-7.68). HRQoL improved consistently following TAVR regardless of measure used. Significant increases occurred in the physical component summary scores (PCS) of the short form (SF) health surveys (MD increase 10.45 (SF36) and 10.14 (SF12) points).

Conclusion

functional capacity and HRQoL improved substantially following TAVR, despite evolving patient selection criteria, thus TAVR continues to provide a directly beneficial option for severe AS patients.

Short- and Long-Term Mortality and Stroke Risk After Transcatheter Aortic Valve Implantation

No published studies have compared the outcome after transcatheter aortic valve implantation (TAVI) with the outcome in the general population. Thus, it is unknown whether TAVI restores normal life expectancy and stroke risk. Furthermore, despite the increasing use of TAVI, only little is known about the temporal trends for TAVI regarding patient characteristics and outcomes. We identified all Danish patients treated with TAVI from 2006 to 2014 (n = 1,631) and 9,737 general population controls matched by gender, age, and co-morbidity. The primary end point was a composite end point of all-cause mortality and stroke. During the first 90 days, the risk of the combined end point, the stroke risk, and mortality were significantly higher among TAVI patients compared with controls (9.4%, 7.5%, and 2.5%, respectively, in TAVI patients compared with 2.0%, 1.6%, and 0.5% in controls). After 90 days, there were no differences (adjusted mortality rate ratio, stroke rate ratio, and mortality or stroke rate ratio 0.92 [0.79 to 1.06], 1.32 [0.98 to 1.78], and 1.00 [0.90 to 1.10], respectively). During the study period, there were small changes in the characteristics of patients treated with TAVI; however, more patients were treated by transfemoral access; fewer needed blood transfusions, hospital stays were shorter, and the overall mortality rate decreased. In conclusion, 90 days after TAVI, the stroke risk and mortality of the TAVI patients were comparable with the stroke risk and mortality of the general population. Over time, the patient risk profiles have remained largely unchanged; however, outcomes have improved substantially, including lower short- and long-term mortality.

Complications After Self-expanding Transcatheter or Surgical Aortic Valve Replacement

Procedural complications following transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) are usually reported as retrospective analyses. We report the first comparison of complications following SAVR or self-expanding TAVR from a prospectively randomized study of high-risk SAVR patients. Three hundred ninety-five TAVR and 402 SAVR patients were prospectively enrolled and randomized 1:1 to TAVR with a CoreValve bioprosthesis or a surgical bioprosthetic valve. The rates of major procedural and vascular complications occurring (periprocedurally (0-3 days) and early (4-30 days)) were compared for TAVR vs SAVR patients. All-cause mortality, stroke, myocardial infarction, and major infection were similar in both periods post procedure. Within 0-3 days, the major vascular complication rate was significantly higher with TAVR (P = 0.003). Life-threatening or disabling bleeding (P < 0.001), encephalopathy (P = 0.02), atrial fibrillation (P < 0.001), and acute kidney injury (P < 0.001) were significantly higher with SAVR. Non-iliofemoral TAVR approaches had a higher incidence of major or life-threatening or disabling bleeding at 0-3days (P < 0.05). Procedural complications unique to TAVR included coronary occlusion 0.5% (2) and TAVR pop outs 2.8% (11) with no valve embolizations. Pop outs were similar between iliofemoral 2.8% (9/324) and non-iliofemoral approaches 3.0% (2/66). Procedural complications unique to SAVR included aortic dissection 0.8% (3/357) and injury to other heart structures 2.0% (7/357). The procedural complication profiles of TAVR and SAVR are unique. Intraoperative deaths were seen in TAVR only. Mortality at 3 and 30 days was similar. The higher incidence of some complications likely reflects the greater invasiveness of SAVR in this aged high-risk population.
