RESUMEN
Remote dielectric sensing (ReDS) system non-invasively quantifies pulmonary congestion. Re-admission following trans-catheter aortic valve replacement (TAVR) remains an unsolved matter. Residual pulmonary congestion is a strong risk factor of worse clinical outcomes in patients with heart failure. ReDS system may have a prognostic impact in patients undergoing TAVR. Patients who received TAVR and ReDS measurements during index hospitalization between 2021 and 2022 were included. The prognostic impact of ReDS value on the composite endpoint of death or re-admission following index discharge was investigated. Totally, 42 patients (median 84 years, 14 men) were included. Median ReDS value at index discharge was 27% (24%, 30%) and 10 patients had ReDS values > 30%. During a median of 316 (282, 354) days following index discharge, a higher ReDS value at baseline was independently associated with the incidence of composite endpoint with an adjusted hazard ratio of 1.32 (95% confidence interval between 1.10 and 1.58) with a calculated cutoff of 30%, which significantly stratified the cumulative incidence of the composite endpoint (78% in the high ReDS group [N = 10] and 36% in the normal ReDS group [N = 32], p = 0.002). ReDS technology may be a promising tool to predict future clinical outcomes following TAVR by quantifying residual pulmonary congestion. The clinical implication of ReDS-guided aggressive intervention following TAVR remains the next concern.

BACKGROUND: Coexistent pulmonary hypertension with severe aortic stenosis confers a greater risk of mortality for patients undergoing transcatheter aortic valve replacement (TAVR). In this patient population, the impact of significant decoupling between pulmonary artery diastolic and pulmonary capillary wedge, as it relates to clinical risk, remained uncertain.MethodsâandâResults:Patients with severe aortic stenosis who underwent TAVR and completed pre-procedural and post-procedural invasive hemodynamic assessments with right heart catheterization were retrospectively assessed. The impact of post-TAVR decoupling, defined as a pressure difference ≥3 mmHg, on 2-year all-cause mortality or risk of heart failure admission was analyzed. Among 77 included patients (median age 86 years, 23 men), 16 had post-TAVR decoupling. The existence of post-TAVR decoupling was associated with a higher cumulative incidence of the primary endpoint (44% vs. 7%, P=0.001), with an adjusted hazard ratio of 5.87 (95% confidence interval 1.58-21.9, P=0.008). CONCLUSIONS: A greater risk of worse outcomes in those with post-TAVR decoupling was observed. A therapeutic strategy for post-TAVR decoupling and its clinical implication need to be created and investigated in the future.

We experienced a 65-year-old woman who was diagnosed as fulminant myocarditis and transferred on mechanical ventilator and veno-arterial extracorporeal membrane oxygenation (ECMO) supports. Impella 5.0 support was additionally initiated to improve pulmonary edema and unload left ventricle. We found a patent foramen ovale (PFO) at the time of Impella insertion by transesophageal echocardiography. Follow-up transesophageal echocardiography found a development of right-to-left shunt flow through PFO accompanying central hypoxia during Impella P8 support. Veno-arterial ECMO was converted to veno-arterio-venous ECMO and PFO was occluded percutaneously on the next day, which stabilized hemodynamics and systemic oxygen supply. In case of Impella 5.0 support, the existence of PFO and the development of right-to-left shunt flow should be carefully surveyed and closed immediately to maintain hemodynamics and systemic oxygen supply.

Remote dielectric sensing (ReDS) is a recently introduced non-invasive electromagnetic-based device used to quantify lung fluid levels. Nevertheless, its inter-rater and intra-rater reliability remain uncertain. In 10 healthy volunteers, ReDS values were measured three times successively by the officially trained expert examiner to validate intra-rater reliability. Similar measures were performed by a total of three examiners to validate inter-rater reliability. Intra-class correlation (ICC) was applied to validate each reliability. Ten healthy volunteers [median 34 (32, 40) years old, 10 men, body mass index 23.0 (21.2, 23.9) ] were included. Median ReDS value was 28% (25%, 31%). For the intra-rater reliability, ICC (1, 1) and ICC (1, 3) were 0.966 and 0.988, respectively (P < 0.001). For the inter-rater reliability, ICC (2, 1) and ICC (2, 3) were 0.683 and 0.866, respectively (P < 0.001). Given almost perfect intra-rater reliability, an examiner does not need to repeat ReDS measurement. Given substantial inter-rater reliability, ReDS measurements had better be measured by multiple examiners if possible.

Mortality and morbidity remain high following transcatheter aortic valve replacement (TAVR) in dialysis patients or those with low left ventricular ejection fraction. Therapeutic strategy for those with these comorbidities remains unestablished. We had a dialysis patient with peripheral artery disease and low left ventricular ejection fraction, who received successfully scheduled trans-apical TAVR following sufficient reverse remodeling by 3-month optimal medical therapy. Our strategy should be validated in a larger robust cohort.

Heart rate reduction therapy using ivabradine has demonstrated its prognostic implication in patients with heart failure with reduced ejection fraction. However, the target heart rate with optimal clinical outcomes, particularly for those with systolic dysfunction following a transcatheter aortic valve replacement (TAVR), remains unknown. Consecutive patients with left ventricular ejection fraction (LVEF) < 50% and sinus rhythm following TAVR received transthoracic echocardiography at index discharge. The ideal heart rate was calculated using a formula: 93 - 0.13 × (deceleration time [ms]). Those whose actual heart rates at discharge were within 10 bpm of the calculated ideal heart rate were assigned to the optimal heart rate group, and their prognosis was compared with those without. Twenty-four patients (83 [78, 85] years old, LVEF 41% [35%, 44%], 16 males) were included. The median difference between actual heart rate and ideal heart rate was 12 (0, 16) bpm and 11 patients were assigned to the optimal heart rate group. One year later, the optimal heart rate group achieved more improvement in LVEF (24% [15%, 28%] vs. 7% [7%, 12%], p = .003) and had lower heart failure readmission rates (0.059 vs. 0.116 events/year; p = .49). In conclusion, an optimal heart rate might be associated with cardiac reverse remodeling and prevention of heart failure recurrences in patients with systolic dysfunction following TAVR. The implication of deceleration time-guided heart rate optimization therapy for such cohorts remains the next concern.

Edge-to-edge repair using the MitraClip system is indicated in patients with severe mitral regurgitation (MR) who are at high risk for open-heart surgery due to comorbidity or reduced cardiac function. However, less is known about pre-procedural risk factors for mortality and morbidity following MitraClip implantation. Consecutive 25 patients with severe MR who underwent MitraClip therapy (mean age, 77 years old, 14 males) were included. Right heart catheterization and echocardiographic data before and after the procedure were collected and their prognostic impacts were investigated. Acute procedural success was 96%. At one week following MitraClip repair, left ventricular ejection fraction (LVEF) remained unchanged and left ventricular end-diastolic volume tended to be smaller. Cardiac index and mean pulmonary artery pressure (mPAP) were markedly improved following the procedure (P < 0.001 for both). In the multivariate analyses using baseline characteristics, both lower LVEF (hazard ratio 0.57, 95% confidence interval 0.30-0.89) and higher mPAP (hazard ratio 1.23, 95% confidence interval 1.06-1.56) were independently associated with post-procedural 1-year death or heart failure readmission (P < 0.05 for both). The lower LVEF and higher mPAP group had lower 1-year survival free from HF readmission compared with those without (16.7% versus 100%; P < 0.001). In conclusion, a combination of baseline mPAP and LVEF might be a useful tool in predicting post-MitraClip procedural clinical outcomes.

Ideal heart rate (HR), particularly for those with heart failure with preserved ejection fraction (HFpEF), remains unknown. We hypothesized that cardiac output would be maximum when the overlap between E-wave and A-wave at the trans-mitral flow is "zero" in the Doppler echocardiography. We retrospectively investigated the association among the overlap length between two waves, actual HR, and other echocardiographic parameters to construct a formula for estimating theoretically ideal HR among those with HFpEF. In total, 48 HFpEF patients were included (70-year-olds, 18 males). Given the results of multivariate linear regression analyses, the overlap length was estimated as follows: -1,050 + 8.4 × (HR [bpm]) + 0.6 × (deceleration time [millisecond]) + 1.7 × (A-width [millisecond]), which had a strong agreement with the actually measured overlap length (r = 0.86, P < 0.001). Theoretically ideal HR was calculated by substituting zero into the estimated overlap length as follows: 125 - 0.07 × (deceleration time [millisecond]) - 0.20 × (A-width [millisecond]). In the validation cohort including another 143 HFpEF patients, the estimated overlap using the formula again had a strong agreement with the actually measured overlap (r = 0.72, P < 0.001). In this study, we proposed a novel formula for calculating theoretically ideal HR, consisting of deceleration time and A-width, in the HFpEF cohort. Clinical implication to optimize the HR targeting the theoretically ideal HR should be investigated in prospective studies.

Background and objectives: Endothelial dysfunction is associated with exercise intolerance and adverse cardiovascular events. Transcatheter aortic valve implantation (TAVI) is applied to treat elderly patients with severe aortic stenosis, but less is known about the impact of TAVI on endothelial dysfunction, which can be assessed by measuring flow-mediated vasodilation (FMD). In this parameter, a low value indicates impaired endothelial function. Materials and Methods: Vascular endothelial function was evaluated by FMD of the brachial artery just before and one week after TAVI. Factors associated with the normalization of FMD and their prognostic impact were investigated. Results: Fifty-one patients who underwent TAVI procedure (median 86 years old, 12 men) were included. FMD improved significantly from baseline to one week following TAVI (from 5.3% [3.7%, 6.7%] to 6.3% [4.7%, 8.1%], p < 0.001). Among 33 patients with baseline low FMD (≤6.0%), FMD normalized up to >6.0% following TAVI in 15 patients. Baseline higher cardiac index was independently associated with normalization of FMD following TAVI (odds ratio 11.8, 95% confidence interval 1.12-124; p < 0.04). Conclusions: Endothelial dysfunction improved following TAVI in many patients with severe aortic stenosis. The implication of this finding is the next concern.

Peri-procedural elevated B-type natriuretic peptide (BNP) is also associated with worse outcomes following transcatheter aortic valve implantation (TAVI). However, the mechanism of BNP regulation in patients with severe aortic stenosis (AS) remains unknown. Consecutive patients with severe AS who were referred for TAVI were enrolled in our prospective registry. BNP levels were correlated with other clinical variables. Ninety-six patients (84.7 ± 5.0 years old, 34% males) were investigated in this study. Plasma BNP averaged 353 ± 179 pg/mL. Log10 BNP had no significant correlation with severity of AS including aortic valve area and maximum flow velocity across the aortic valve (P > 0.05 for all), whereas a higher left ventricular end-diastolic dimension (LVDd) index was a significant factor associating with BNP >100 pg/mL with an odds ratio of 1.34 (95% confidence interval 1.06-1.52, P = 0.004) adjusted for several other echocardiographic parameters, with a cutoff of 30.8 mm/m2 (equivalent to LVDd 44 mm). In conclusion, among the patients with severe AS who undergo TAVI, even slight eccentric hypertrophy can cause a considerable increase in BNP level.

BACKGROUND: Abnormalities in the left atrium (LA) detected on transesophageal echocardiography (TEE) are reliable predictors of thromboembolism in patients with atrial fibrillation (AF). Cardiac troponin I, a marker of subclinical myocardial damage, may also be a predictor of thromboembolic events in patients with AF. The relationship between cardiac troponin I and thromboembolic risk on TEE, however, remains unclear.MethodsâandâResults:TEE and laboratory data, including high sensitivity cardiac troponin I (hs-cTnI) and CHA2DS2-VASc score, were analyzed in 199 patients with non-valvular AF (NVAF). Patients were stratified into those with or without LA abnormality, defined as LA appendage flow velocity <20 cm/s or dense spontaneous echo contrast. On multiple logistic analysis of the clinical variables, hs-cTnI was associated with LA abnormality (95% CI: 1.0003-1.020, P=0.034). The area under the curve for LA abnormality increased on addition of hs-cTnI to CHA2DS2-VASc score. The incidence rate of ischemic stroke was higher in the high hs-cTnI group than in the low-hs-cTnI group (log-rank test, P<0.05). CONCLUSIONS: Elevated hs-cTnI was independently associated with LA abnormality in NVAF patients. hs-cTnI level may be a useful biomarker for risk stratification of thromboembolism in NVAF patients.

BACKGROUND: There is a consensus that overactivation of the cardiac sympathetic nervous system (CSN) proportionately increases the severity of heart failure and is accompanied by worse prognosis. Because it is unknown whether patients with aortic valve stenosis (AS) have similar CSN activation, we investigated the effect of transcatheter aortic valve implantation (TAVI).MethodsâandâResults:We enrolled 31 consecutive patients with AS treated by TAVI. 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy was performed at baseline and at 2 weeks after TAVI. At baseline, the early heart-mediastinum ratio (H/M) was within normal limits (3.0±0.5), but the delayed H/M was low (2.6±0.6) and the washout rate (WR) was high (34±13%). WR negatively correlated with aortic valve area (r=-0.389, P<0.01) and cardiac output (r=-0.595, P<0.01) and positively correlated with norepinephrine (r=0.519, P<0.01) and log NT-proBNP level (r=0.613, P<0.01). After TAVI, there were significant decreases in the norepinephrine level (366±179 ng/mL vs. 276±125 ng/mL, P<0.01) and WR (34±13 vs. 26±11%, P<0.01). CONCLUSIONS: The WR of MIBG was a useful marker of CSN activity and severity of AS. Immediate improvement of CSN activity after TAVI implied that AS hemodynamics per se enhanced CSN.

An 85-year-old man with severe aortic stenosis (transaortic peak velocity 4.4 m/s, mean gradient 46 mmHg and valve area 0.71 cm(2)) was admitted to our hospital due to mild exertional dyspnea (NYHA class II). He had received low-dose prednisolone (5 mg/day) plus tacrolimus hydrate (1.5 mg/day) for rheumatic arthritis and interstitial pneumonia. Although aortic valve replacement was indicated, he was considered at high risk to undergo open heart surgery because of reduced pulmonary function (FEV1.0%, 77.2%) and long-term treatment with immunosuppressive drugs. After a multidisciplinary heart team conference, the decision was made to perform transfemoral transcatheter aortic valve implantation (TAVI) using a SAPIEN XT 26 mm valve. TAVI was completed in 105 minutes without any complications. After the procedure, his symptom was improved and his activity of daily life was maintained, and he was ambulatory the next day. Aortic stenosis by degenerative calcification is becoming increasingly common as the Japanese population ages. TAVI has been used to treat patients with concomitant diseases and at high risk of open heart surgery. We herein report a case with rheumatic arthritis and interstitial pneumonia that underwent successful TAVI.

BACKGROUND: There is no clear consensus on thromboprophylaxis in patients with nonvalvular atrial fibrillation (AF) at low-intermediate thromboembolic risk. Although hyperuricemia is a risk factor for cardiovascular diseases, the relationship between serum uric acid (UA) levels and thromboembolic risk has not been fully elucidated in patients with AF. METHODS AND RESULTS: Serum UA levels and the score for congestive heart failure, hypertension, age, diabetes mellitus, prior stroke/transient ischemic attack, vascular disease and sex (ie, CHA2DS2-VASc score) were determined in 470 patients with nonvalvular AF who underwent transesophageal echocardiography (TEE) to evaluate their risk of thromboembolism. Serum UA levels were similar between the low-intermediate risk (CHA2DS2-VASc score=0 or 1) and high-risk (≥2) groups, although serum D-dimer levels were lower in the low-intermediate risk than in the high-risk group. Among patients at low-intermediate risk, serum UA levels were higher in those with TEE thromboembolic risk (TEE risk: low left atrial appendage flow, spontaneous echo contrast, thrombi, or aortic atherosclerosis) than in those without TEE risk. On multivariate analysis, the serum UA level was an independent predictor of TEE risk in AF patients at low-intermediate risk (odds ratio, 1.45; 95% confidence interval 1.09-2.00; P=0.016). CONCLUSIONS: The serum UA level was associated with thromboembolic risk on TEE in patients with nonvalvular AF at low-intermediate risk stratified by clinical risk factors.

BACKGROUND: Transcatheter atrial septal closures for secundum atrial septal defects (ASD) have demonstrated favorable clinical outcomes. However, the impact of device implantation on the stiffness of the left atrium remains unclear. METHOD: Patients with secundum ASD undergoing transcatheter closure and follow-up right heart catheterization at six months were included. We investigated the relationship between post-procedural (E/e' ratio)/(LAs strain) ratio, an index of left atrial stiffness, and baseline characteristics, including echocardiographic and hemodynamic parameters. RESULTS: Forty patients were included (median 69 (56, 75) years, 12 men, and pulmonary systemic flow ratio 2.27 (1.96, 2.86)). Trans-catheter ASD closure was successfully performed without any major complications, accompanying a significant reduction in right ventricular to left ventricular size ratio from 1.04 (0.87, 1.13) to 0.74 (0.66, 0.86) (p < 0.01). The (E/e' ratio)/(LAs strain) ratio was markedly elevated the day after the procedure and was further increased 6 months later (before: 0.25 (0.17, 0.34), 1 day later: 0.34 (0.27, 0.50), 6 months later: 0.43 (0.27, 0.76), p < 0.01). The groups with higher (E/e' ratio)/(LAs strain) ratios at 6 months had significantly more severe heart failure conditions including lower cardiac output and higher plasma B-type natriuretic peptides. CONCLUSIONS: Patients undergoing transcatheter ASD closure experienced improvement in hemodynamics and clinical symptoms but an elevation in left atrial stiffness post-procedure. The clinical ramifications of this finding, particularly during the longer-term observation period subsequent to ASD closure, warrant further investigation.
RESUMEN
BACKGROUND: The presence of insomnia exhibits a profound association with diverse cardiovascular pathologies. However, its prognostic implications in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis remain ambiguous. METHODS: This retrospective study enrolled patients who underwent TAVR for severe aortic stenosis at a prominent academic center from 2015 to 2022. The impact of insomnia, operationally defined as the prescription of soporific agents, on the two-year composite primary outcome comprising all-cause mortality and hospital readmissions was scrutinized. RESULTS: A cohort of 345 patients (median age 85â¯years, 99 males) was encompassed in the analysis. All subjects underwent successful TAVR and subsequent discharge. The presence of insomnia (Nâ¯=â¯91) emerged as an independent predictor of the two-year composite endpoint, with an adjusted hazard ratio of 1.66 (95â¯% confidence interval 1.08-2.57, pâ¯=â¯0.022), significantly delineating the two-year cumulative incidence of the primary endpoint (40â¯% versus 30â¯%, pâ¯=â¯0.035). CONCLUSION: Approximately one-fourth of TAVR candidates manifested symptoms of insomnia, a condition autonomously correlated with heightened mortality and morbidity following the TAVR procedure. The optimal strategy for addressing insomnia in TAVR candidates constitutes a paramount consideration for future interventions.

Background: Impaired gastric motility in the form of constipation may often occur in elderly patients with chronic heart failure. Candidates for trans-catheter aortic replacement (TAVR) are of old age and have multiple comorbidities, probably including constipation. However, the clinical implication of a history of constipation in patients receiving TAVR remains unknown. Methods: Patients who underwent TAVR at our large academic center between 2015 and 2022 were eligible. The prognostic impact of the prescribed laxative type and number, which was assumed as the severity of constipation, on the incidence of death or heart failure readmission two years after index discharge was investigated. Results: A total of 344 patients were included. Median age was 85 years, and 99 patients were men. Patients with any laxatives (N = 166) had higher systolic blood pressure, higher plasma B-type natriuretic peptide levels, and a lower prescription rate of renin-angiotensin system inhibitors at the time of index discharge after TAVR (p < 0.05 for all). The number of laxative types was independently associated with the composite primary outcome with an adjusted hazard ratio of 1.83 (95% confidence interval 1.27-2.63, p = 0.001) with a cutoff of one type of laxative used, which significantly stratified the 2-year cumulative incidence of the primary outcome (18% versus 7%, p = 0.001). Conclusions: The presence of constipation was associated with worse clinical outcomes following TAVR. The prognostic impact of an aggressive intervention for constipation remains a future concern in this cohort.
RESUMEN
Patients with severe aortic stenosis often experience pulmonary congestion due to incremental afterload. The trajectory of pulmonary fluid volume during transcatheter aortic valve replacement (TAVR) remains uncertain. Remote dielectric sensing (ReDS) is a recently introduced device for non-invasive quantification of lung fluid volume without expert techniques. We evaluated the trajectory of ReDS values during TAVR and its prognostic implications. Patients with severe aortic stenosis who underwent ReDS measurements upon admission and at the index discharge after TAVR between 2021 and 2022 were eligible. They were followed up until August 2023. The primary focus was on the trajectory of ReDS values during TAVR, with secondary consideration given to its impact on the composite of death or all-cause readmission after TAVR. A total of 57 patients were included. Median age was 84 years and 24 were male. ReDS value remained unchanged after TAVR, changing from 27% (IQR 24%, 29%) to 26% (IQR 24%, 30%) (p = 0.65). ReDS value did not decrease in 23 (40%) patients. The presence of coronary artery disease and atrial fibrillation were associated with no decrease in ReDS value. This lack of decrease in ReDS value was linked to death or all-cause readmission after TAVR, with an age-adjusted hazard ratio of 3.40 (95% confidence interval 1.01-11.4, p = 0.048). The degree of lung fluid amount did not decrease in 40% of TAVR candidates during the procedure. The lack of decrease in lung fluid amount was associated with mortality and morbidity after TAVR. The next concern is to establish therapeutic strategy for patients with residual pulmonary congestion after TAVR.

AIMS: Remote dielectric sensing (ReDS) represents a contemporary non-invasive technique reliant on electromagnetic energy to quantify pulmonary congestion. Its prognostic significance within the context of heart failure (HF) patients remains elusive. This study aimed to assess the prognostic implications of residual pulmonary congestion, as gauged by the ReDS system, among patients admitted due to congestive HF. METHODS AND RESULTS: We enrolled hospitalized HF patients who underwent ReDS assessments upon admission and discharge in a blinded manner, independent of attending physicians. We evaluated the prognostic impact of the ReDS ratio between admission and discharge on the primary outcome, which encompassed all-cause mortality and HF-related re-hospitalizations. A cohort of 133 patients (median age 78 [72, 84] years, 78 male [59%]) was included. Over a median observation period of 363 days post-index discharge, an escalated ReDS group (ReDS ratio > 100%), determined through statistical calculation, emerged as an independent predictor of the primary outcome, exhibiting an adjusted hazard ratio of 4.37 (95% confidence interval 1.13-16.81, P = 0.032). The cumulative incidence of the primary outcome was notably higher in the increased ReDS group compared with the decreased ReDS group (50.1% vs. 8.5%, P = 0.034). CONCLUSIONS: Elevated ReDS ratios detected during the index hospitalization could serve as a promising prognostic indicator in HF patients admitted for treatment. The clinical ramifications of ReDS-guided HF management warrant validation in subsequent studies.

Background: Transcatheter edge-to-edge mitral valve repair (TEER) has emerged as a viable approach to addressing substantial secondary mitral regurgitation. In the contemporary landscape where ultimate heart failure-specific therapies, such as cardiac replacement modalities, are available, prognosticating a high-risk cohort susceptible to early cardiac mortality post-TEER is pivotal for formulating an effective therapeutic regimen. Methods: Our study encompassed individuals with secondary mitral regurgitation and chronic heart failure enlisted in the multi-center (Optimized CathEter vAlvular iNtervention (OCEAN)-Mitral registry. We conducted an assessment of baseline variables associated with cardiac death within one year following TEER. Results: Amongst the 1517 patients (median age: 78 years, 899 males), 101 experienced cardiac mortality during the 1-year observation period after undergoing TEER. Notably, a history of heart failure-related admissions within the preceding year, utilization of intravenous inotropes, and elevated plasma B-type natriuretic peptide levels emerged as independent prognosticators for the primary outcome (p < 0.05 for all). Subsequently, we devised a novel risk-scoring system encompassing these variables, which significantly stratified the cumulative incidence of the 1-year primary outcome (16%, 8%, and 4%, p < 0.001). Conclusions: Our study culminated in the development of a new risk-scoring system aimed at predicting 1-year cardiac mortality post-TEER.
