Aortic valve replacement among patients with Alzheimer's disease and related dementias.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has made palliation from aortic stenosis more broadly available to populations previously thought to be too high risk for surgery, such as those with Alzheimer's disease and related dementias (ADRD); however, its safety and effectiveness in this context are uncertain. METHODS: We performed a retrospective cohort study of national Medicare beneficiaries, aged 66 and older with Parts A and B, between 2010 and 2016. Patients undergoing AVR were identified, and follow-up was available through 2017. Multivariable regression was used to measure the independent association between having a diagnosis of ADRD at the time of AVR, stratified by TAVR and surgery, and outcomes (mortality and Medicare institutional days at 1 year after AVR). RESULTS: The average rate of increase in AVR per year was 17.5 cases per 100,000 ADRD and 8.4 per 100,000 non-ADRD beneficiaries, largely driven by more rapid adoption of TAVR. Adjusted mortality following AVR declined significantly between those treated in 2010 and 2016, from 13.5% (95% CI 10.2%-17.7%) to 6.3% (95% CI 5.2%-7.6%) and from 13.7% (95% CI 12.7%-14.7%) to 6.3% (95% CI 5.8%-6.9%) in those with and without ADRD, respectively. The sharpest decline was noted for patients undergoing TAVR between 2011 and 2016, with adjusted mortality declining from 19.9% (95% CI 11.2%-32.8%) to 5.2% (95% CI 4.1%-6.5%) and from 12.2% (95% CI 9.3%-15.8%) to 5.0% (95% CI 4.4%-5.6%) in patients with and without ADRD, respectively. Similar declines were evident for Medicare institutional days in the year after AVR in both patient groups. CONCLUSIONS: Rates of AVR in those with ADRD increased during the past decade largely driven by the diffusion of TAVR. The use of TAVR in this vulnerable population did not come at the expense of increasing Medicare institutional days or mortality at 1-year.

Quality of life in sexagenarians after aortic biological vs mechanical valve replacement: a single-center study in China.

OBJECTIVE: This article aimed to study the quality of life and anxiety of sexagenarian patients who underwent aortic biological vs mechanical valve replacement in a single center in China. METHODS: The clinical data of 78 patients aged 60 to 70 years who underwent aortic prosthetic valve replacement were retrospectively analyzed in our hospital from June 2017 to February 2018. Patients were divided into two groups depending on the type of prosthetic valve they received (biological valve group vs mechanical valve group). The SF-36 was completed by all patients at discharge and at one-year follow-up, and the cardiac anxiety questionnaire (CAQ) was also completed at one-year follow-up. RESULTS: There was no statistically significant difference between the two groups in general clinical data or SF-36 score at discharge. However, at one-year follow-up, the SF-36 scores were significantly higher in the biological valve group than in the mechanical valve group, and the CAQ scores in fear and anxiety, avoidance and attention in the mechanical valve group were significantly higher than those in the biological valve group. CONCLUSIONS: Based on the postoperative quality of life and anxiety scores of sexagenarian patients who underwent biological vs mechanical valve replacement in this study, a biological valve has more value than a mechanical valve for sexagenarians undergoing aortic valve replacement.

The Learning Curve for Shared Decision-making in Symptomatic Aortic Stenosis.

Importance: Shared decision-making (SDM) is widely advocated for patients with valvular heart disease yet is not integrated into the heart team model for patients with symptomatic aortic stenosis. Decision aids (DAs) have been shown to improve patient-centered outcomes and may facilitate SDM. Objective: To determine whether the repeated use of a DA by heart teams is associated with greater SDM, along with improved patient-centered outcomes and clinician attitudes about DAs. Design, Setting, and Participants: This mixed-methods study included a nonrandomized pre-post intervention and clinician interviews. It was conducted between April 30, 2015, and December 7, 2017, with quantitative analysis performed between January 12, 2017, and May 26, 2017, within 2 academic medical centers in northern New England among 35 patients with symptomatic aortic stenosis who were at high to prohibitive risk for surgery. The qualitative analysis was performed between August 6, 2018, and May 7, 2019. The Severe Aortic Stenosis Decision Aid was delivered by 6 clinicians, with patients choosing between transcatheter aortic valve replacement and medical management. Main Outcomes and Measures: Clinician SDM performance was measured using the Observer OPTION5 scale with dual-independent coding of audiotaped clinic visits. Previsit and postvisit surveys measured the patient's knowledge, satisfaction, and decisional conflict. Audiotaped clinician interviews were coded, and qualitative thematic analysis was performed. Results: Six male clinicians and 35 patients (19 of 34 women [55.9%; 1 survey was missing]; mean [SD] age, 85.8 [7.8] years) participated in the study. Shared decision-making increased stepwise with repeated use of the DA (mean [SD] Observer OPTION5 scores: usual care, 17.9 [7.6]; first use of a DA, 60.5 [30.9]; fifth use of a DA, 79.0 [8.4]; P < .001 for comparison between usual care and fifth use of DA). Multiple uses of the DA were associated with increased patient knowledge (mean difference, 18.0%; 95% CI, 1.2%-34.8%; P = .04) and satisfaction (mean difference, 6.7%; 95% CI, 2.5%-10.8%; P = .01) but not decisional conflict (mean [SD]: usual care, 96.0% [9.4%]; first use of DA, 93.8% [12.5%]; fifth use of DA, 95.0% [11.2%]; P = .60). Qualitative analysis of clinicians' interviews revealed that clinicians perceived that they used an SDM approach without DAs and that the DA was not well understood by elderly patients. There was infrequent values clarification or discussion of stroke risk. Conclusion and Relevance: In a mixed-methods pilot study, use of a DA for severe aortic stenosis by heart team clinicians was associated with improved SDM and patient-centered outcomes. However, in qualitative interviews, heart team clinicians did not perceive a significant benefit of the DA, and therefore sustained implementation is unlikely. This pilot study of SDM clarifies new research directions for heart teams.

Effect of transcatheter aortic valve implantation on health-related quality of life in older adults with multimorbidity.

PURPOSE: The purpose of this study was to determine the effect of transcatheter aortic valve implantation on health-related quality of life in older adults with multimorbidity and to evaluate the predictive factors for postoperative quality of life impairment in such patients. MATERIAL AND METHOD: This study included 141 older adults with severe aortic stenosis scheduled for elective transcatheter aortic valve implantation. Quality of life was examined in all patients using the Short-Form 36 Health Survey Questionnaire, before and 2 years after surgery. Comorbidity was assessed using the Charlson Comorbidity Index. RESULTS: In older adult patients with aortic stenosis and multimorbidity, transcatheter aortic valve implantation significantly improved both physical and mental components of quality of life 2 years after surgery. A Charlson Comorbidity Index ≥5 points was independently associated with the absence of positive dynamics in Physical Health score [odds ratio (OR) 0.38 (0.20-0.75), p = 0.007]. Charlson Comorbidity Index ≥5 points [OR 0.31 (0.19-0.58), p = 0.026] and new-onset arrhythmia [OR 0.54 (0.38-0.78), p = 0.017] were independent predictors of the absence of positive dynamics in Mental Health score after transcatheter aortic valve implantation. CONCLUSIONS: High-level comorbidity (Charlson Comorbidity Index ≥5 points) predicts both Physical and Mental Health scores for quality of life impairment following transcatheter aortic valve implantation in older adults, and new-onset arrhythmia predicts the Mental Health score for quality of life impairment following transcatheter aortic valve implantation in these patients.

[Dynamics of Quality of Life in Patients With Aortic Stenosis After Aortic Valve Replacement With a Biological or Mechanical Prosthesis].

OBJECTIVE: To assess dynamics of the quality of life (QOL) in patients of the older age group of with initial aortic stenosis in 1, 3, and 5 years after replacement of the aortic valve (AV) with biological or mechanical prosthesis. MATERIALS AND METHODS: QOL was assessed in 282 patients who underwent aortic valve replacement with a biological or mechanical prosthesis. Criterion for inclusion in this retrospective single-center study was primary and elective nature of the operation. Patients with repeated interventions (early postoperative resternotomy, reosteosynthesis, repeat aortic valve surgery) were not included. Using the method of Propensity Score Matching, we distributed 151 patients in whom the long-term results of AV replacement were analyzed according to age, gender, body mass index into groups of AV replacement with biological (group 1, n=74) and mechanical (group 2, n=77) prosthesis. RESULTS: In the early period after operation, there was no significant difference between groups in parameters of quality of life. During the observation period up to 3 years significant increases of parameters bodily pain (BP), vitality (VT), and mental health (MH) occurred in patients with biological prostheses, while physical functioning (PF) was higher in patients with mechanical prostheses. At follow-up to 5 years, indicators such as BP and role emotional functioning (RE) became higher in patients with mechanical prostheses. According to the conducted regression analysis the type of prosthesis affected the quality of life. CONCLUSIONS: 1) AV replacement with mechanical prostheses was associated with lowering of the physical component of health by 81.1%, and of the mental health component - by 56.6% per month; 2) significant difference in QOL between groups of patients with mechanical and biological prostheses could be detected only in 3 years after the operation: parameters BP, VT and MH were significantly higher in patients with biological prostheses, while PF was higher in patients with mechanical prostheses; 3) in the longer observation period (up to 5 years) parameters BP and RE became higher in patients with mechanical prostheses.

Self-reported health status, treatment decision and survival in asymptomatic and symptomatic patients with aortic stenosis in a Western Norway population undergoing conservative treatment: a cross-sectional study with 18 months follow-up.

OBJECTIVES: To investigate symptoms and self-reported health of patients conservatively treated for aortic stenosis (AS) and to identify factors associated with treatment decision and patient outcomes. DESIGN: A cross-sectional survey with an 18-month follow-up. SETTING: One tertiary university hospital in Western Norway. PARTICIPANTS: In all, 1436 patients were diagnosed with AS between 2000 and 2012, and those 245 still under conservative treatment in 2013 were included in this study. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome measures were symptoms and self-reported health status. Secondary outcomes were treatment decision and patient survival after 18 months. RESULTS: A total of 136 patients with mean (SD) age 79 (12) years, 52% men responded. Among conservatively treated patients 77% were symptomatic. The symptom most frequently experienced was dyspnoea. Symptomatic patients reported worse physical and mental health compared with asymptomatic patients (effect size 1.24 and 0.74, respectively). In addition, symptomatic patients reported significantly higher levels of anxiety and depression compared with asymptomatic patients. However, symptom status did not correlate with haemodynamic severity of AS. After 18 months, 117 (86%) were still alive, 20% had undergone surgical aortic valve replacement (AVR) and 7% transcatheter aortic valve implantation (TAVI). When adjusting for age, gender, symptomatic status, severity of AS and European system for cardiac operative risk evaluation (EuroSCORE), patients with severe AS had more than sixfold chance of being scheduled for AVR or TAVI compared with those with moderate AS (HR 6.3, 95% CI 1.9 to 21.2, p=0.003). Patients with EuroSCORE ≥11 had less chance for undergoing AVR or TAVI compared with those with EuroSCORE ≤5 (HR 0.06, 95% CI 0.01 to 0.46, p=0.007). CONCLUSIONS: Symptoms affected both physical and mental health in conservatively treated patients with AS. Many patients with symptomatic severe AS are not scheduled for surgery, despite the recommendations in current guidelines. The referral practice for AVR is a path for further investigation.

The Impact of Frailty on Patient-Centered Outcomes Following Aortic Valve Replacement.

BACKGROUND: Frailty confers risk for surgical morbidity and mortality. Whether patient-reported measures of health, well-being, or quality of life respond differently to surgery in non-frail and frail individuals is unknown. METHODS: Older adults with severe aortic stenosis presenting for surgery were assessed for frailty using Cardiovascular Health Study Criteria. Patient-reported measures of functional capacity (Duke Activity Status Index [DASI]), physical and mental health (Medical Outcomes Study Short Form-Physical and Mental Component Scales [SF-12 PCS and SF-12 MCS, respectively]), well-being (linear analogue self-assessment [LASA]), and quality of life (LASA) were administered before and 3 months after surgery. RESULTS: Of 103 participants (mean age of 80.6 years), 54 were frail. Frail participants had lower baseline DASI, SF-12 PCS, SF-12 MCS, physical well-being, and quality of life scores than non-frail participants. At follow-up, frail participants showed significant improvement in physical function, with DASI and SF-12 PCS scores improving by 50% and 14%, respectively. Non-frail subjects did not significantly improve in these measures. SF-12 MCS scores also improved to a greater extent in frail compared to non-frail participants (3.6 vs < 1 point). Furthermore, the frail participants improved to a greater extent than non-frail participants in physical well-being (21.6 vs 7.1 points) and quality of life measures (25.1 vs 8.7 points). CONCLUSIONS: Frailty is prevalent in older adults with severe aortic stenosis and is associated with poor physical and mental function, physical well-being, and quality of life. In response to surgery, frail participants exhibited greater improvement in these patient-centered outcomes than non-frail peers.

New Ventricular Septal Defects Following Balloon-Expandable Transcatheter Aortic Valve Replacement.

Transcatheter aortic valve replacement (TAVR) has been commercially approved in the United States for the treatment of high-risk and inoperable patients with severe symptomatic aortic stenosis. While TAVR has proven benefits with regard to survival and quality of life in studied populations, the procedure is also associated with several well-described complications including stroke, vascular injury, and paravalvular regurgitation. More infrequent complications are less well described. Here, we report the development of new ventricular septal defects after TAVR in 4 patients with left ventricular outflow tract calcification. We discuss imaging and post-TAVR management of these patients.

Transition to palliative care when transcatheter aortic valve implantation is not an option: opportunities and recommendations.

PURPOSE OF REVIEW: Transcatheter aortic valve implantation (TAVI) is the recommended treatment for most patients with symptomatic aortic stenosis at high surgical risk. However, TAVI may be clinically futile for patients who have multiple comorbidities and excessive frailty. This group benefits from transition to palliative care to maximize quality of life, improve symptoms, and ensure continuity of health services. We discuss the clinical determination of utility and futility, explore the current evidence guiding the integration of palliative care in procedure-focused cardiac programs, and outline recommendations for TAVI programs. RECENT FINDINGS: The determination of futility of treatment in elderly patients with aortic stenosis is challenging. There is a paucity of research available to guide best practices when TAVI is not an option. Opportunities exist to build on the evidence gained in the management of end of life and heart failure. TAVI programs and primary care providers can facilitate improved communication and processes of care to provide decision support and transition to palliative care. SUMMARY: The increased availability of transcatheter options for the management of valvular heart disease will increase the assessment of people with life-limiting conditions for whom treatment may not be an option. It is pivotal to bridge cardiac innovation and palliation to optimize patient outcomes.

High aortic pulse wave velocity is associated with poor quality of life in surgical aortic valve stenosis patients.

OBJECTIVES: Aortic stiffness is an emerging risk factor for cardiovascular disease. The predictive value of aortic pulse wave velocity (PWV) for quality of life (QoL) and severity of surgical aortic valve stenosis (AS) have not been examined. METHODS: PWV was measured in patients undergoing aortic valve replacement (AVR) for AS. QoL [SF-36 and European QoL 5-dimensions (EQ-5D) questionnaires] was assessed pre- and postoperatively (409 ± 159 days). PWV was analysed: (i) as a continuous variable and (ii) as a dichotomous variable (PWV-norm and PWV-high groups) according to the published normal reference value. RESULTS: Fifty-six patients (16 females), mean age of 71 ± 8.4 years, were included, and 50 (89%) patients completed follow-up. The two groups were matched for age, gender and classical haemodynamic measurements. There was no significant relation between AS severity and PWV. PWV-norm patients (n = 35) scored significantly better than PWV-high (n = 21) patients in the EQ-5D visual analogue scale and the EQ-5D index pre- (P < 0.001 and P = 0.03, respectively) and postoperatively (P < 0.001 for both). In SF-36, PWV-norm group scored better than PWV-high group in physical health domains preoperatively and in all domains postoperatively. Spearman's correlation was significant between PWV and QoL component summaries pre- and postoperatively. Among PWV, age and gender, multiple regression analysis demonstrated PWV to be independently related to QoL pre- and postoperatively (P-values ranged from <0.01 to <0.05). CONCLUSIONS: PWV does not correlate with AS severity, but is associated with QoL before and after AVR. The published European PWV reference values can be used to categorise preoperative AS patients for QoL risk stratification.

Health-related quality of life following isolated aortic valve surgery: is earlier intervention better?

BACKGROUND AND AIM OF THE STUDY: The study aim was to determine the health-related quality of life (HRQL) in conjunction with clinical outcomes following aortic valve replacement (AVR) surgery. In these times of healthcare change, quality measures of the success of a procedure go beyond clinical outcomes, with patient reports of HRQL considered important. METHODS: All patients who had undergone AVR surgery were followed prospectively through the authors' valve registry and the local Society of Thoracic Surgery (STS) database. The HRQL (Short-Form 12 and Minnesota Living with Heart Failure Questionnaire) was collected preoperatively, and at six and 12 months after surgery. RESULTS: Since 2005, a total of 459 patients have undergone isolated AVR surgery. The mean age, ejection fraction and STS risk score were 65.8 +/- 13.6 years, 57.7 +/- 11.0%, and 2.8 +/- 3.5 (range: 0.4-47.9), respectively. The median (IQR) length of hospital stay was 5 (3-7) days. Compared to the STS national norms, all clinical outcomes were excellent. A Kaplan-Meier analysis showed the two year cumulative survival as 92.0%. After 12 months the physical and mental HRQL had improved significantly, surpassing age and heart disease norms (p < 0.001 and p = 0.02, respectively). Multivariate analysis determined that a higher 12-month physical HRQL was predicted by a lower STS risk score (B = -1.3, p < 0.001) and a lower perioperative morbidity (B = -5.5, p = 0.02) after adjustment for baseline HRQL, age, and gender. In a subset of patients classified as 'symptomatic', as determined by higher MLHF scores, the HRQL scores were increased to age norms and surpassed the heart disease norms. CONCLUSION: Patients who undergo AVR can expect excellent clinical and HRQL outcomes, with greater benefits the earlier the surgery is carried out. The tracking of HRQL is valuable in understanding the success of a procedure from the patients' perspective.

Demographic changes and increase of the average life span led to the increase of elderly patients, who need cardiac surgery. The issue highlights the results of surgical activity of cardiosurgery department of SCS among elderly patients.

A systematic review on the quality of life benefits after aortic valve replacement in the elderly.

BACKGROUND: Surgical aortic valve replacement is being increasingly performed in elderly patients with good perioperative outcomes and long-term survival. Evidence is limited on health-related quality of life after aortic valve replacement, which is an important measure of operative success in the elderly. METHODS: A systematic review of clinical studies after January 2000 was performed to identify health-related quality of life in the elderly after aortic valve replacement. Strict inclusion and exclusion criteria were applied. Quality appraisal of each study also was performed using predefined criteria. Health-related quality of life results were synthesized through a narrative review with full tabulation of the results of all included studies. RESULTS: Health-related quality of life improvements were shown across most or all domains in different health-related quality of life instruments. Elderly patients experienced marked symptomatic improvement. Health-related quality of life was equivalent or superior to both an age-matched population and younger patients undergoing identical procedures. There were excellent functional gains after surgery, but elderly patients remain susceptible to geriatric issues and mood problems. Concomitant coronary artery bypass did not affect health-related quality of life. There was a diverse range of study designs, methods, and follow-up times that limited direct comparison between studies. CONCLUSIONS: Aortic valve replacement results in significant health-related quality of life benefits across a broad range of health domains in elderly patients. Age alone should not be a precluding factor for surgery. Data are heterogeneous and mostly retrospective. We recommend future studies based on consistent guidelines provided in this systematic review.

Quality of life in high-risk patients: comparison of transcatheter aortic valve implantation with surgical aortic valve replacement.

OBJECTIVES: To compare health-related quality of life (QoL) in patients undergoing transcatheter aortic valve implantation via transapical access (TA TAVI) with patients undergoing surgical aortic valve replacement (SAVR). METHODS: One hundred and forty-four high-risk patients referred for aortic valve replacement underwent TAVI screening and were assigned to either TA TAVI (n = 51, age 79.7 ± 9.2 years, logistic EuroSCORE 26.5 ± 16.1%, 51% males) or SAVR (n = 93, age 81.1 ± 5.3 years, logistic EuroSCORE 12.1 ± 9.3%, 42% males) by the interdisciplinary heart team. QoL was assessed using the Short Form 36 (SF-36) Health Survey Questionnaire and the Hospital Anxiety and Depression Scale. Furthermore, current living conditions and the degree of independence at home were evaluated. RESULTS: Patients undergoing TA TAVI were at higher risk as assessed by EuroSCORE (26.5 ± 16 vs. 12.1 ± 9, P < 0.001) and STS score (6.7 ± 4 vs. 4.4 ± 3, P < 0.001) compared with SAVR patients. At the 30-day follow-up, the rate of mortality was similar and amounted to 7.8% for TA TAVI and 7.5% for SAVR patients and raised to 25.5% in TA TAVI and 18.3% in SAVR patients after a follow-up period of 15 ± 10 months. Assessment of QoL revealed no differences in terms of anxiety and depression between TA TAVI and SAVR patients. The SF-36 mental health metascore was similar in both groups (65.6 ± 19 vs. 68.8 ± 22, P = 0.29), while a significant difference was observed in the physical health metascore (49.7 ± 21 vs. 62.0 ± 21, P = 0.015). After adjustment for baseline characteristics, this difference disappeared. However, every added point in the preoperative risk assessment with the STS score decreased the SF-36 physical health dimension by two raw points at the follow-up assessment. CONCLUSIONS: Selected high-risk patients undergoing TAVI by using a transapical access achieve similar clinical outcomes and QoL compared with patients undergoing SAVR. Increased STS scores predict worse QoL outcomes.

The German Aortic Valve Registry (GARY): a nationwide registry for patients undergoing invasive therapy for severe aortic valve stenosis.

Background The increasing prevalence of severe aortic valve defects correlates with the increase of life expectancy. For decades, surgical aortic valve replacement (AVR), under the use of extracorporeal circulation, has been the gold standard for treatment of severe aortic valve diseases. In Germany ~12,000 patients receive isolated aortic valve surgery per year. For some time, percutaneous balloon valvuloplasty has been used as a palliative therapeutic option for very few patients. Currently, alternatives for the established surgical procedures such as transcatheter aortic valve implantation (TAVI) have become available, but there are only limited data from randomized studies or low-volume registries concerning long-time outcome. In Germany, the implementation of this new technology into hospital care increased rapidly in the past few years. Therefore, the German Aortic Valve Registry (GARY) was founded in July 2010 including all available therapeutic options and providing data from a large quantity of patients.Methods The GARY is assembled as a complete survey for all invasive therapies in patients with relevant aortic valve diseases. It evaluates the new therapeutic options and compares them to surgical AVR. The model for data acquisition is based on three data sources: source I, the mandatory German database for external performance measurement; source II, a specific registry dataset; and source III, a follow-up data sheet (generated by phone interview). Various procedures will be compared concerning observed complications, mortality, and quality of life up to 5 years after the initial procedure. Furthermore, the registry will enable a compilation of evidence-based indication criteria and, in addition, also a comparison of all approved operative procedures, such as Ross or David procedures, and the use of different mechanical or biological aortic valve prostheses.Results Since the launch of data acquisition in July 2010, almost all institutions performing aortic valve procedures in Germany joined the registry. By now, 91 sites which perform TAVI in Germany participate and more than 15,000 datasets are already in the registry.Conclusion The implementation of new or innovative medical therapies needs supervision under the conditions of a well-structured scientific project. Up to now relevant data for implementation of TAVI and long-term results are missing. In contrast to randomized controlled trials, GARY is a prospective, controlled, 5-year observational multicenter registry, and a real world investigation with only one exclusion criterion, the absence of patients' written consent.

The use of reconstructive surgery to improve quality of life and survival in prenatal hypoplastic left heart syndrome.

Outcomes for hypoplastic left heart syndrome have improved substantially in the era of prenatal diagnosis. Current stage 1 survival rates are in excess of 90% in the absence of risk factors. However, fetuses with an intact atrial septum continue to have poor postnatal survival. Accurate diagnosis of these fetuses with an intact atrial septum relies upon careful assessment of the patent foramen ovale, pulmonary venous Doppler flow patterns and branch pulmonary artery Doppler flow patterns. Prenatal and perinatal interventions, such as the placement of an atrial stent in utero or delivery at a center where a stent may be placed immediately after birth to relieve left atrial hypertension, may improve survival in this particularly high-risk group.

Critical review of health-related quality of life studies of patients with aortic stenosis.

BACKGROUND: While studies of health-related quality of life (HRQOL) are increasing among cardiovascular patients, very few have examined HRQOL in persons with aortic stenosis (AS). PURPOSE: A critical review of studies (1997-2008) of HRQOL in persons with AS was conducted to summarize findings and identify clinical and research implications. RESULTS: Twenty-eight studies were identified, all of which were quantitative and evaluated HRQOL after aortic valve replacement (AVR). No studies conducted by nurses or studies measuring HRQOL in persons who did not undergo AVR were found. The literature focused on age and type of valve as variables influencing HRQOL postoperatively. Although results varied, elderly patients often scored similar or better than comparison groups. Health-related quality of life was found to be affected by valve noise and anticoagulation rather than the specific valve type when comparing patients receiving biological versus mechanical valves. CONCLUSIONS: Selection for surgery should not be based on age alone. Early consideration should be given to symptoms prior to surgery because of evidence that patients with fewer symptoms preoperatively have better HRQOL after AVR. Anticoagulation status should be evaluated as an independent variable of HRQOL in future studies. IMPLICATIONS FOR RESEARCH AND PRACTICE: Researchers need to augment generic HRQOL measures with disease-specific items that may pertain to life areas affected by AS, such as audible valve click, wound healing, and dyspnea. Future research should be inclusive of AS patients who do not undergo surgery. Nurses in a variety of roles can work independently or within a multidisciplinary team to provide interventions for the promotion of HRQOL for patients across all stages of the AS disease process.

Surgical management of aortic valve disease in elderly patients with and without coronary artery disease: influence on quality of life.

AIM: The feasibility of coronary artery bypass grafting (CABG) concomitant with aortic valve replacement (AVR) is well established. However, its impact on long-term patient-perceived quality of life (QoL) in the elderly remains undefined. METHODS: Retrospective analysis was conducted on 866 patients 65 years of age and over who underwent AVR between October 1976 and December 1999 with a Carpentier-Edwards porcine bioprosthesis. This cohort was divided between those who underwent isolated AVR (n=438) and those with AVR and concomitant CABG (AVR+CABG; n=428). Mean age was 77.0+/-6.1 years (range, 65 to 91) in the AVR group and 78.2+/-5.5 years (range, 65 to 93) in the AVR+CABG group. QoL was assessed with the Short Form-36 health survey for survivors at follow-up, which was 97% complete. RESULTS: Operative mortality (OM) was 6.2% (27/438) for the AVR group and 8.9% (38/428) for the AVR+CABG group (P=0.130). The occurrence of hospital complications (P=0.162) and postoperative length of stay (P=0.980) was similar for the 2 groups. Actuarial survival at 10 years was 37.1+/-3.4% for AVR and 38.7+/-4% for AVR+CABG patients (P=0.088). On multivariate analyses, CABG was not a predictor of either OM or long-term survival. QoL was similar for the 2 groups on the summary components: physical health (39.4+/-11.4 versus 40.2+/-12.1; P=0.461) and mental health (50.2+/-10.8 versus 51.9+/-10.1; P=0.103). CONCLUSIONS: Despite the presence of severe coronary artery disease, CABG preserved the long-term QoL in elderly patients undergoing AVR.

[Quality of life in patients after the Ross operation for aortic stenosis]. / Jakosc zycia u pacjentów po korekcji lewego ujscia tetniczego metoda Rossa.

The pulmonary autograft provides ideal conditions regarding hemodynamics. Its additional value is durability and low thromboembolic hazard. We postulated that the Ross technique results in minimal restrictions on patient's lifestyle as compared to normal controls and we expected the patients to have good quality of life (QoL). On the other hand QoL may be affected by the risk of the homograft degeneration and the need of reoperation in the future. The aim of the study was to assess the QoL of patients after Ross operation because of aortic valve stenosis. Postoperative condition of the patients was judged by resting transthoracic echo, 24 hour ECG recording, maximal exercise test on bicycle ergometer. The mean age of patients was 31.1 (N=50; 18 female, 32 male). The mean follow-up was 3.6 years. We applied the Short Form Health Survey Questionnaire (SF-36) for assessment of QoL. The results of psychological tests were compared with age, gender and education matched control group without underlying cardiac disease. Overall QoL (QoL index) did not vary between patients and control group. The only significant difference concerned physical sum score and subtests of physical functioning (scale 1) and general health perception (scale 8). There were no differences in psychological health sum score. We concluded that in general, patients after the Ross operation enjoy a normal life style. The results of our study are consistent with well known advantages of Ross procedure. This study also implies the need for more detailed information concerning patient's lifestyle after the operation. Patient's family and doctors who are to take care of the patient after leaving hospital ought to be instructed as well. Education should specify patient's ability to perform different everyday abilities, especially physical ones. The aim of the education is to eliminate negative self-assessment of patient's own physical abilities which probably originate from preoperative period and stress connected with operation.
