Two-year Outcomes of Ventricular-demand Leadless Pacemaker Therapy for Heart Block After Transcatheter Aortic Valve Replacement. J Innov Card Rhythm Manag 2023; 14:5491-5498. [PMID: 37388425 PMCID: PMC10306247 DOI: 10.19102/icrm.2023.14062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Accepted: 01/23/2023] [Indexed: 07/01/2023] Open
Abstract
Ventricular-demand leadless pacemakers (VVI-LPMs) have often been used as an alternative to atrioventricular (AV) synchronous transvenous pacemakers (DDD-TPMs) in patients with high-grade AV block following transcatheter aortic valve replacement (TAVR). However, the clinical outcomes of this unusual usage are not elucidated. Patients who received permanent pacemakers (PPMs) owing to new-onset high-grade AV block after TAVR from September 2017 to August 2020 at a high-volume center in Japan were included in the analysis, and the clinical courses of VVI-LPM and DDD-TPM implants through 2 years of follow-up were compared retrospectively. Out of 413 consecutive patients who underwent TAVR, 51 (12%) patients received a PPM. After excluding 8 patients with chronic atrial fibrillation (AF), 3 with sick sinus syndrome, and 1 with incomplete data, 17 VVI-LPMs and 22 DDD-TPMs were included in our final cohort. The VVI-LPM group had lower serum albumin levels (3.2 ± 0.5 vs. 3.9 ± 0.4 g/dL, P < .01) than the DDD-TPM group. Follow-up revealed no significant differences between the 2 groups in terms of the incidence of late device-related adverse events (0% vs. 5%, log-rank P = .38) and new-onset AF (6% vs. 9%, log-rank P = .75); however, there were increases in the rates of all-cause death (41% vs. 5%, log-rank P < .01) and heart failure rehospitalization (24% vs. 0%, log-rank P = .01) in the VVI-LPM group. This small retrospective study reveals favorable post-procedural complication rates but higher all-cause mortality with VVI-LPM compared to DDD-TPM therapy for high-grade AV block after TAVR at 2 years of follow-up.

Efficacy and Safety of Home-Based Cardiac Telemonitoring Rehabilitation in Patients After Transcatheter Aortic Valve Implantation: Single-Center Usability and Feasibility Study. JMIR Rehabil Assist Technol 2023; 10:e45247. [PMID: 37195764 DOI: 10.2196/45247] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 04/06/2023] [Accepted: 04/28/2023] [Indexed: 05/18/2023] Open
Abstract
BACKGROUND No consensus exists on the efficacy of home-based cardiac rehabilitation (CR) in patients who have undergone transcatheter aortic valve implantation (TAVI). Additionally, there are no reports on home-based cardiac telemonitoring rehabilitation (HBTR) in patients after TAVI. OBJECTIVE We aimed to investigate the efficacy of HBTR in patients who have undergone TAVI. METHODS This single-center preliminary study introduced HBTR to patients after TAVI, and the efficacy outcomes of the rehabilitation method were compared to that of a historical control cohort. The historical control cohort (control group) consisted of 6 consecutive patients who underwent ordinary outpatient CR after TAVI from February 2016 to March 2020. Patients who participated in the HBTR program were only recruited after the TAVI procedure and before discharge between April 2021 and May 2022. In the first 2 weeks after TAVI, patients underwent outpatient CR and were trained using telemonitoring rehabilitation systems. Thereafter, patients underwent HBTR twice a week for 12 weeks. The control group performed standard outpatient CR at least once a week for 12 to 16 weeks. Efficacy was assessed using peak oxygen uptake (VO2) prior to and after CR. RESULTS Eleven patients were included in the HBTR group. All patients underwent 24 HBTR sessions during the 12-week training period, and no adverse events were observed. The control group participants performed 19 (SD 7) sessions during the training period, and no adverse events were observed. Participants in the HBTR and control groups had a mean age of 80.4 (SD 6.0) years and 79.0 (SD 3.9) years, respectively. In the HBTR group, preintervention and postintervention peak VO2 values were 12.0 (SD 1.7) mL/min/kg and 14.3 (SD 2.7) mL/min/kg (P=.03), respectively. The peak VO2 changes in the HBTR and control groups were 2.4 (SD 1.4) mL/min/kg and 1.3 (SD 5.0) mL/min/kg (P=.64), respectively. CONCLUSIONS Home-based CR using a telemonitoring system is a safe outpatient rehabilitation method. Its efficacy is not inferior to that of standard CR in patients who have undergone TAVI.

Functional continuum: independent predictor of one-year mortality and key decision-making element in older adults with severe aortic stenosis amenable to aortic valve replacement. Aging Clin Exp Res 2023; 35:323-331. [PMID: 36417136 DOI: 10.1007/s40520-022-02300-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Accepted: 11/02/2022] [Indexed: 11/24/2022]
Abstract
OBJECTIVES The impact of functional capacity over the entire functional continuum in older adults undergoing aortic valve replacement (AVR) has not been studied to date. This study aims to analyze 1.- the distribution of a cohort of older adults presenting severe aortic stenosis (AS) amenable to AVR in the different categories of the Functional Continuum Scale (FCS); 2.- its association with decision-making regarding valve disease; and 3.- its impact upon the one-year mortality rate of surgical (SAVR), transcatheter (TAVR) aortic valve replacement, or the decision to provide conservative management (OMT). METHODS This prospective study included patients from the FRESAS (FRailty-Evaluation-in-Severe-Aortic-Stenosis) registry evaluated by the reference Heart-Team of a region in northern Spain. All the patients underwent comprehensive geriatric assessment. RESULTS The study comprised 257 patients aged 84.0 ± 3.9 years. MANAGEMENT SAVR: 25.3%, TAVR: 58.0% and OMT: 16.7%. Increased patient functional capacity was associated with an increased tendency to perform more invasive valve disease treatment. The overall one-year survival rate was 81.3%. One-year all-cause mortality: FCS-1 to FCS-2 "robust" 11.5%, FCS-3 to FCS-4 "prefrail" 14.7%, FCS-5 "frail" 19.2% and FCS-6 to FCS-8 "dependent" 45.0%; p < 0.001. Adjusted mortality analysis: FCS with HR = 1.206 [95%CI, 0.999-1.451 (p = 0.051)]; EuroSCORE-II with HR = 1.071 [95%CI, 1.006-1.161 (p = 0.033)]; and OMT with HR = 2.840 [95%CI, 1.409-5.772 (p = 0.004)] were retained in the final multivariable logistic regression model. CONCLUSIONS In older AS patients amenable to AVR, the FCS is a useful predictive tool that may aid clinical decision-making.

Abstract
Background The usefulness of preprocedural nutritional status to stratify prognosis after transcatheter aortic valve implantation has been evaluated; however, the studies conducted so far have been relatively small and/or focused on a single nutritional index. This study sought to assess the prevalence and prognostic impact of malnutrition in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation. Methods and Results We applied the Controlling Nutritional Status score, Geriatric Nutritional Risk Index, and Prognostic Nutritional Index to 1040 consecutive older Japanese patients at high surgical risk who underwent transcatheter aortic valve implantation. According to the Controlling Nutritional Status score, Geriatric Nutritional Risk Index, and Prognostic Nutritional Index, 16.6%, 60.5%, and 13.8% patients had moderate or severe malnutrition, respectively; 89.3% were at least mildly malnourished by at least 1 score. Worse nutritional status was associated with older age, lower body mass index, higher degree of frailty, worse symptoms and renal function, atrial fibrillation, and anemia. During a median follow-up of 986 days (interquartile range, 556-1402 days), 273 (26.3%) patients died. Compared with normal nutrition, malnutrition was associated with an increased risk for all-cause death (adjusted hazard ratio for moderate and severe malnutrition, respectively: 2.19 (95% CI, 1.45-3.31; P<0.001) and 6.13 (95% CI, 2.75-13.70; P<0.001) for the Controlling Nutritional Status score, 2.02 (95% CI, 1.36-3.02; P=0.001) and 3.24 (95% CI, 1.86-5.65; P<0.001) for the Geriatric Nutritional Risk Index, and 1.60 (95% CI, 1.06-2.39; P=0.024) and 2.32 (95% CI, 1.50-3.60; P<0.001) for the Prognostic Nutritional Index). Conclusions Malnutrition is common in patients undergoing transcatheter aortic valve implantation and is associated with increased mortality.

Abstract
Aims Older adults at risk for malnutrition are known to have a high mortality rate. This study aimed to investigate whether the Mini Nutritional Assessment—Short Form (MNA‐SF) could predict midterm mortality in patients undergoing transcatheter aortic valve implantation (TAVI). Methods and results We applied the MNA‐SF in 288 patients who had undergone TAVI from January 2016 to June 2019 at the St. Marianna University School of Medicine hospital. Using the MNA‐SF cut‐off value to indicate the risk of malnutrition, patients were divided into two groups, namely, those with an MNA‐SF score ≤11 (impaired MNA‐SF group) and those with an MNA‐SF score ≥12 (maintained MNA‐SF group). We used this value to investigate the association between the MNA‐SF and all‐cause mortality. Overall, 188 (65%) and 100 (35%) patients comprised the impaired MNA‐SF and maintained MNA‐SF groups, respectively, and 41 patients died after TAVI (mean follow‐up duration, 458 ± 315 days). Kaplan–Meier analyses showed that patients in the impaired MNA‐SF group had a significantly higher incidence of all‐cause mortality (hazard ratio 2.67; 95% confidence interval 1.29–6.21; P = 0.01). Multivariate Cox regression analyses showed that the MNA‐SF score was an independent predictor of all‐cause mortality after adjusting for the Society of Thoracic Surgeons risk score, Katz Index, and brain natriuretic peptide test results (hazard ratio 1.14; 95% confidence interval 1.01–1.28; P = 0.04). Conclusions The MNA‐SF was useful to screen for the risk of malnutrition in patients with TAVI and in predicting midterm prognoses in patients undergoing TAVI and could predict patient mortality after the procedure.
