Outcomes of Transcatheter Tricuspid Edge-to-Edge Repair in Patients With Right Ventricular Dysfunction.

BACKGROUND: We assessed the safety profile of tricuspid transcatheter edge-to-edge repair (TEER) in patients with right ventricular (RV) dysfunction. METHODS: We identified patients undergoing TEER to treat tricuspid regurgitation from June 2015 to October 2021 and assessed tricuspid annular plane systolic excursion (TAPSE) and RV fractional area change (RVFAC). RV dysfunction was defined as TAPSE <17 mm and RVFAC <35%. The primary end point was 30-day mortality after TEER. We also investigated the change in the RV function in the early phase and clinical outcomes at 2 years. RESULTS: The study participants (n=262) were at high surgical risk (EuroSCORE II, 6.2% [interquartile range, 4.0%-10.3%]). Among them, 44 patients met the criteria of RV dysfunction. Thirty-day mortality was 3.2% in patients with normal RV function and 2.3% in patients with RV dysfunction (P=0.99). Tricuspid regurgitation reduction to ≤2+ was consistently achieved irrespective of RV dysfunction (76.5% versus 70.5%; P=0.44). TAPSE and RVFAC declined after TEER in patients with normal RV function (TAPSE, 19.0±4.7 to 17.9±4.5 mm; P=0.001; RVFAC, 46.2%±8.1% to 40.3%±9.7%; P<0.001). In contrast, those parameters were unchanged or tended to increase in patients with RV dysfunction (TAPSE, 13.2±2.3 to 15.3±4.7 mm; P=0.011; RVFAC, 29.6%±4.1% to 31.6%±8.3%; P=0.14). Two years after TEER, compared with patients with normal RV function, patients with RV dysfunction had significantly higher mortality (27.0% versus 56.3%; P<0.001). CONCLUSIONS: TEER was safe and feasible to treat tricuspid regurgitation in patients with RV dysfunction. The decline in the RV function was observed in patients with normal RV function but not in patients with RV dysfunction.

Can the ADO Index Be Used as a Predictor of Mortality from COVID-19 in Patients with COPD?

Background: Several studies have shown that the risk of mortality due to COVID-19 is high in patients with COPD. However, evidence on factors predicting mortality is limited. Research Question: Are there any useful markers to predict mortality in COVID-19 patients with COPD?. Study Design and Methods: A total of 689 patients were included in this study from the COPET study, a national multicenter observational study investigating COPD phenotypes consisting of patients who were followed up with a spirometry-confirmed COPD diagnosis. Patients were also retrospectively examined in terms of COVID-19 and their outcomes. Results: Among the study patients, 105 were diagnosed with PCR-positive COVID-19, and 19 of them died. Body mass index (p= 0.01) and ADO (age, dyspnoea, airflow obstruction) index (p= 0.01) were higher, whereas predicted FEV1 (p< 0.001) and eosinophil count (p= 0.003) were lower in patients who died of COVID-19. Each 0.755 unit increase in the ADO index increased the risk of death by 2.12 times, and each 0.007 unit increase in the eosinophil count decreased the risk of death by 1.007 times. The optimum cut-off ADO score of 3.5 was diagnostic with 94% sensitivity and 40% specificity in predicting mortality. Interpretation: Our study suggested that the ADO index recorded in the stable period in patients with COPD makes a modest contribution to the prediction of mortality due to COVID-19. Further studies are needed to validate the use of the ADO index in estimating mortality in both COVID-19 and other viral respiratory infections in patients with COPD.

Changes in right ventricular function and clinical outcomes following tricuspid transcatheter edge-to-edge repair.

AIMS: Prognostic impact of post-procedural changes in right ventricular (RV) function after tricuspid transcatheter edge-to-edge repair (T-TEER) is still unclear. We investigated association of RV function and its post-procedural changes with clinical outcomes in patients undergoing T-TEER. METHODS AND RESULTS: We retrospectively analysed 204 patients who underwent T-TEER and echocardiographic follow-up at 3 months after T-TEER. RV function was assessed by RV fractional area change (RVFAC), and RV dysfunction was defined as RVFAC <35%. Patients with an increase in RVFAC from baseline to the follow-up were considered as RV responders. Patients were divided into four groups according to baseline RVFAC and the RV responder. The primary outcome was a composite of mortality and hospitalization due to heart failure within 1 year. Forty-five of 204 patients (22.1%) had RVFAC <35% at baseline, and 71 (34.8%) were RV responders. The association between the RV responder and the composite outcome had a significant interaction with RVFAC at baseline. Among patients with baseline RVFAC <35%, RV responders had a lower risk of the composite outcome than RV non-responders, while this association was not significant in those with baseline RVFAC ≥35%. Among patients with baseline RVFAC <35%, a smaller RV diameter and a greater reduction of tricuspid regurgitation were predictors for the RV responder. CONCLUSION: Post-procedural increase in RVFAC after T-TEER is associated with improved outcomes in patients with RV dysfunction. The factors related to the increase in RVFAC may support patient selection for T-TEER in patients with RV dysfunction.

Bimaxillary Immediate Prosthetic Rehabilitation Using a Custom Maxillary Subperiosteal Implant and Fibula-Free Flap Mandibular Reconstruction After Tumor Ablation.

Subperiosteal implants (SPIs) using rigid fixation have recently emerged as an acceptable alternative to conventional endosteal implants when there is limited or absent alveolar bone. Modern advances in digital technology and manufacturing have improved the usability and stability of this latest generation of SPIs. Herein, we present the first reported case of a modern patient-specific SPI placed in the United States and, to the authors' knowledge, the first reported case performed in conjunction with a simultaneous free flap reconstruction of the opposing arch, and immediate dental rehabilitation of both arches in the world.

Outcomes of transcatheter edge-to-edge repair for atrial functional mitral regurgitation.

BACKGROUND: The prognostic benefits of transcatheter edge-to-edge repair (TEER) remain unclear in patients with atrial functional mitral regurgitation (AFMR). AIMS: We aimed to investigate the clinical outcomes of TEER for patients with AFMR. METHODS: We retrospectively classified functional mitral regurgitation (FMR) patients undergoing TEER into those with AFMR or ventricular FMR (VFMR). A residual MR ≤1+ at discharge was considered optimal mitral regurgitation (MR) reduction, and an elevated mean mitral valve pressure gradient (MPG) was defined as an MPG ≥5 mmHg at discharge. The primary outcome was a composite of all-cause mortality and hospitalisation due to heart failure within one year. RESULTS: Of 441 FMR patients, 125 patients were considered as having AFMR. Residual MR ≤1+ was associated with a lower risk of the composite outcome in both AFMR and VFMR patients, while an MPG ≥5 mmHg was associated with a higher risk of the composite outcome in patients with AFMR but not with VFMR. AFMR patients with residual MR ≤1+ and an MPG ≥5 mmHg, as well as those with residual MR >1+, had a higher incidence of the composite outcome than those with residual MR ≤1+ and an MPG <5 mmHg (50.7%, 41.8%, and 14.3%, respectively; p<0.001). This association was consistent after adjustment for clinical and echocardiographic characteristics. CONCLUSIONS: An MR reduction to ≤1+ following TEER was associated with a lower risk of clinical outcomes in patients with AFMR, while an MPG ≥5 mmHg was related to a higher risk of clinical outcomes. Optimal MR reduction by TEER may have potential benefits on the prognosis of patients with AFMR, although the prognostic benefit may be attenuated by an elevated MPG.

Impact of body mass index in patients with tricuspid regurgitation after transcatheter edge-to-edge repair.

BACKGROUND: Obesity and underweight represent classical risk factors for outcome in patients treated for cardiovascular disease. This study describes the impact of different body mass index (BMI) categories on 1-year clinical outcome in patients with tricuspid regurgitation (TR) undergoing transcatheter-edge-to-edge repair (TEER). METHODS: We analyzed 211 consecutive patients (age 78.3 ± 7.2 years, 55.5% female, median EuroSCORE II 9.6 ± 6.7) with tricuspid regurgitation undergoing TEER from June 2015 until May 2021. Patients were prospectively enrolled in our single center registry and were retrospectively analyzed. Patients were stratified according to body mass index (BMI) into 4 groups: BMI < 20 kg/m2 (underweight), BMI 20.0 to < 25.0 kg/m2 (normal weight), BMI 25.0 to > 30.0 kg/m2 (overweight) and BMI ≥ 30 kg/m2 (obese). RESULTS: Kaplan-Meier survival curves demonstrated inferior survival for underweight and obese patients, but comparable outcomes for normal and overweight patients (global log rank test, p < 0.01). Cardiovascular death was significantly higher in underweight patients compared to the other groups (24.1% vs. 7.0% vs. 6.3% vs. 6.4%; p < 0.01). Over all, there were comparable rates of bleeding, stroke and myocardial infarction. Multivariable Cox regression analysis (adjusted for age, gender, coronary artery disease, chronic obstructive pulmonary disease, tricuspid annular plane systolic excursion, left-ventricular ejection fraction) confirmed underweight (HR 3.88; 95% CI 1.64-7.66; p < 0.01) and obesity (HR 3.24; 95% CI 1.37-9.16; p < 0.01) as independent risk factors for 1-year all-cause mortality. CONCLUSIONS: Compared to normal weight and overweight patients, obesity and underweight patients undergoing TEER display significant higher 1-year all-cause mortality.

Refining accuracy of RV-PA coupling in patients undergoing transcatheter tricuspid valve treatment.

BACKGROUND: Assessing right ventricular (RV) function is paramount for risk stratification, which remains challenging in patients with tricuspid regurgitation (TR). We assessed RV-pulmonary artery (PA) coupling and its predictability of outcomes after transcatheter tricuspid valve repair (TTVR). METHODS: Study participants comprised patients undergoing transcatheter tricuspid valve repair to treat symptomatic TR from June 2015 to July 2021. We calculated an RV-PA coupling ratio using a formula, which is dividing tricuspid annular plane systolic excursion (TAPSE) by echocardiographically estimated (ePASP) or invasively measured PASP (iPASP) at baseline. The primary outcome was all-cause mortality or heart failure rehospitalization within one year. RESULTS: The study participants (n = 206) were at high surgical risk (EuroSCORE II: 7.4 ± 4.8%). The primary outcome occurred in 57 patients within one year. The c-statistics for the outcome were 0.565 (95% CI 0.488-0.643) for TAPSE/ePASP and 0.695 (95% CI 0.631-0.759) for TAPSE/iPASP. The correlation between the ePASP and iPASP was attenuated in patients with massive/torrential TR compared to those with severe TR (interaction p = 0.01). In the multivariable Cox proportional model, TAPSE/iPASP was inversely associated with the risk of the primary outcome (per 0.1-point increase: adjusted-HR 0.67, 95% CI 0.56-0.82, p < 0.001), independent of baseline demographics. According to the TAPSE/iPASP quartiles (i.e., ≤ 0.316; 0.317-0.407; 0.408-0.526; ≥ 0.527), the event-free survival was 43.4%, 48.3%, 77.9%, and 85.4% at one year after TTVR. CONCLUSION: RV-PA coupling predicts one-year mortality and heart failure rehospitalization after TTVR in patients with TR. The predictability is improved if invasively-measured PA pressure is included.

One-Year Outcomes According to Mitral Regurgitation Etiology Following Transcatheter Edge-to-Edge Repair With the PASCAL System: Results From a Multicenter Registry.

BACKGROUND: We previously reported procedural and 30-day outcomes of a German early multicenter experience with the PASCAL system for severe mitral regurgitation (MR). This study reports 1-year outcomes of mitral valve transcatheter edge-to-edge repair with the PASCAL system according to MR etiology in a large all-comer cohort. METHODS AND RESULTS: Clinical and echocardiographic outcomes up to 1-year were investigated according to MR etiology (degenerative [DMR], functional [FMR], or mixed [MMR]) in the first 282 patients with symptomatic MR 3+/4+ treated with the PASCAL implant at 9 centers in 2019. A total of 282 patients were included (33% DMR, 50% FMR, 17% MMR). At discharge, MR reduction to ≤1+/2+ was achieved in 58%/87% of DMR, in 75%/97% of FMR, and in 78%/98% of patients with MMR (P=0.004). MR reduction to ≤1+/2+ was sustained at 30 days (50%/83% DMR, 67%/97% FMR, 74%/100% MMR) and at 1 year (53%/78% DMR, 75%/97% FMR, 67%/91% MMR) with significant differences between etiologies. DMR patients with residual MR 3+/4+ at 1-year had at least complex valve morphology in 91.7%. Valve-related reintervention was performed in 7.4% DMR, 0.7% FMR, and 0.0% MMR (P=0.010). At 1-year, New York Heart Association Functional Class was significantly improved irrespective of MR etiology (P<0.001). CONCLUSIONS: In this large all-comer cohort, mitral valve transcatheter edge-to-edge repair with the PASCAL system was associated with an acute and sustained MR reduction at 1-year in all causes. However, in patients with DMR, MR reduction was less pronounced, reflecting the high incidence of complex or very complex anatomies being referred for mitral valve transcatheter edge-to-edge repair.

Postpartum Breastfeeding Practices and Attitudes in Parents: A Randomized Study to Evaluate the Effects of Individual and Group Breastfeeding Education of Mothers and Fathers.

Background Antenatal breastfeeding training is defined as the provision of breastfeeding information during pregnancy, which can be given in various ways, such as individual training and group training. The inclusion of fathers in this educational approach is associated with the initiation of breastfeeding, exclusive breastfeeding and duration of breastfeeding. However, studies involving fathers are limited. This randomized controlled study aimed to compare the effects of individual and group training given to parents and those of normal hospital practices on mothers' breastfeeding self-efficacy and fathers' attitudes toward breastfeeding. Methods The study was conducted randomly in a training and research hospital between March 2014 and September 2014 and included 180 people. Of them, 90 were prospective mothers who were in the third trimester of their pregnancy and were living with their husbands and received service from the obstetrics outpatient clinic of the hospital. The expecting mothers and their husbands were randomly assigned to three groups: individual training, group training and control group. After randomization, prospective mothers and fathers in all groups received training. In the first week, sixth week, and fourth month after delivery, the mothers' breastfeeding self-efficacy and breastfeeding attitudes as well as the attitudes of the fathers' toward breastfeeding were evaluated. Results There were no differences between the groups in terms of variables such as age, education status, family type, breastfeeding education status, and mode of delivery. There were significant differences between the scores obtained from the Breastfeeding Self-Efficacy Scale and its subscales in all three groups during the postpartum period (p <0.05). The highest scale scores were obtained at the postpartum fourth month in the individual training and control groups and at the postpartum sixth week in the group training group. There were differences between the scores obtained by the mothers and fathers during the postpartum process from the Iowa Infant Feeding Attitude Scale (p<0.05). Conclusion The analysis of all the results indicates that breastfeeding education given to parents in the antenatal period increases their breastfeeding self-efficacy and provides them with a positive attitude toward breastfeeding. However, further research is needed to determine whether individual or group training contributes to the development of breastfeeding self-efficacy and attitudes.

Seroma After Breast Reconstruction With Tissue Expanders: Outcomes and Management.

BACKGROUND: Seroma is a relatively common complication after breast reconstruction with tissue expanders. The main risk in the presence of seroma is development of periprosthetic infection, which can lead to implant loss. Our goals were to identify risk factors for seroma, and to describe our protocol for managing fluid accumulation. PATIENTS AND METHODS: An IRB approved breast reconstruction database was reviewed to identify patients who underwent tissue expander reconstruction. Patient characteristics, details of surgery, outcomes and treatment were recorded. RESULTS: Two hundred nineteen tissue expander reconstructions were performed in 138 patients. Twenty-eight reconstructions developed seroma (12.8%), and 75 were identified to have prolonged drains (34.2%). Seroma was more common in patients with lymph node surgery ( P = 0.043), delayed reconstruction ( P = 0.049), and prepectoral reconstruction ( P = 0.002). Seroma and/or prolonged drains were more commonly noted in patients with higher body mass index ( P = 0.044) and larger breast size ( P = 0.001). Aspiration was the most common intervention (85.7%), which was performed in the clinic utilizing the expander port site. There was no difference in infection or explantation rate between seroma and no-seroma patients ( P = 0.546 and 0.167), whereas patients with any fluid concern (seroma and/or prolonged drains) were more prone to developing infection and undergoing explantation ( P = 0.041 and P < 0.005). CONCLUSION: We recommend that prolonged drain placement longer than 3 weeks should be avoided, and patients should be screened for fluid accumulation after drain removal. Serial aspiration via expander port site and continuation of expansion provide a safe and effective method to manage seromas to avoid infection and expander loss.

Right ventricular ejection fraction assessed by computed tomography in patients undergoing transcatheter tricuspid valve repair.

AIMS: The role of right ventricular function in patients undergoing transcatheter tricuspid valve repair (TTVR) is poorly understood. This study investigated the association of right ventricular ejection fraction (RVEF) assessed by cardiac computed tomography (CCT) with clinical outcomes in patients undergoing TTVR. METHODS AND RESULTS: We retrospectively assessed three-dimensional (3D) RVEF by using pre-procedural CCT images in patients undergoing TTVR. RV dysfunction was defined as a CT-RVEF of <45%. The primary outcome was a composite outcome, consisting of all-cause mortality and hospitalization due to heart failure, within 1 year after TTVR. Of 157 patients, 58 (36.9%) presented with CT-RVEF <45%. Procedural success and in-hospital mortality were comparable between patients with CT-RVEF <45% and ≥45%. However, CT-RVEF of <45% was associated with a higher risk of the composite outcome (hazard ratio: 2.99; 95% confidence interval: 1.65-5.41; P = 0.001), which had an additional value beyond two-dimensional echocardiographic assessments of RV function to stratify the risk of the composite outcome. In addition, patients with CT-RVEF ≥45% exhibited the association of procedural success (i.e. residual tricuspid regurgitation of ≤2+ at discharge) with a decreased risk of the composite outcome, while this association was attenuated in those with CT-RVEF <45% (P for interaction = 0.035). CONCLUSION: CT-RVEF is associated with the risk of the composite outcome after TTVR, and a reduced CT-RVEF might attenuate the prognostic benefit of TR reduction. The assessment of 3D-RVEF by using CCT may refine the patient selection for TTVR.

Tricuspid valve anatomy of massive to torrential tricuspid regurgitation: Computed tomography analysis.

BACKGROUND: We aimed to comprehensively assess tricuspid valve anatomy and to determine factors associated with the more advanced stages beyond severe TR (i.e., massive to torrential). METHODS: We retrospectively analyzed the pre-procedural cardiac CT images in patients with ≥severe TR using 3mensio software. The tricuspid valve annulus size, right-atrial and right-ventricular dimensions, tenting height, and leaflet angles were measured. RESULTS: A total of 103 patients were analyzed. The mean effective regurgitant orifice area was 61.7 â€‹± â€‹31.5 â€‹mm2, vena contracta was 13.1 â€‹± â€‹4.6 â€‹mm, and massive/torrential TR was observed in 62 patients. Compared to patients with severe TR, patients with massive/torrential TR had a larger tricuspid annulus area (18.6 â€‹± â€‹3.4 â€‹cm2 vs. 20.6 â€‹± â€‹5.3 â€‹cm2, p â€‹= â€‹0.037), right atrial short-axis diameter (66.1 â€‹± â€‹9.1 â€‹mm vs. 70.6 â€‹± â€‹9.9 â€‹mm, p â€‹= â€‹0.022), increased tenting height (8.8 â€‹± â€‹3.6 â€‹mm vs. 10.7 â€‹± â€‹3.7 â€‹mm, p â€‹= â€‹0.014), and greater leaflet angles (anterior leaflet: 22 â€‹± â€‹9° vs. 32 â€‹± â€‹13°, p â€‹< â€‹0.001; posterior leaflet: 22 â€‹± â€‹11° vs. 30 â€‹± â€‹11°, p â€‹= â€‹0.003). In the multivariable logistic regression model, the angle of anterior leaflet (OR 1.08, 95%CI 1.03-1.14, p â€‹= â€‹0.004) and posterior leaflet (OR 1.07, 95%CI 1.02-1.13, p â€‹= â€‹0.007) were associated with massive/torrential TR. Additionally, patients with massive/torrential TR more often had TR jets from non-central/non-anteroseptal commissure (34% vs. 76%, p â€‹< â€‹0.001). In the multivariable model, a greater angle of the leaflets and a more elliptical annulus were associated with non-central/non-anteroseptal TR jets. CONCLUSIONS: Anterior and posterior leaflet angles are significant factors associated with massive/torrential TR. Furthermore, leaflet angles and ellipticity of the tricuspid valve are associated with the location of TR jets.

Early Outcomes of 2 Mitral Valve Transcatheter Leaflet Approximation Devices: A Propensity Score-Matched Multicenter Comparison.

BACKGROUND: In addition to the edge-to-edge MitraClip repair system, the edge-to-spacer PASCAL repair system was approved for percutaneous treatment of severe mitral regurgitation (MR). Comparative data are lacking. OBJECTIVES: The aim of this study was to compare procedural and short-term safety and efficacy of 2 leaflet-based transcatheter mitral valve repair systems. METHODS: Procedural and 30-day outcomes were investigated in a propensity score-matched cohort of 307 PASCAL and 307 MitraClip patients at 10 sites. Matching criteria included sex, age, left ventricular ejection fraction, New York Heart Association functional class, MR etiology, left ventricular end-diastolic diameter, left atrial volume index, and vena contracta width. The primary efficacy endpoints were technical success and degree of residual MR at discharge. The primary safety endpoint was the rate of major adverse events (MAE). RESULTS: Technical success was 97.0% in the PASCAL group and 98.0% in the MitraClip group (P = 0.624). MR ≤2+ at discharge was comparable in both groups (PASCAL: 93.8% vs MitraClip: 92.4%; P = 0.527), with more patients exhibiting MR ≤1+ in the PASCAL group (70.5% vs 56.6%; P < 0.001). The postprocedural mean gradient was significantly higher in the MitraClip group (3.3 ± 1.5 mm Hg vs 3.9 ± 1.7 mm Hg; P < 0.001). At 30 days, all-cause mortality and MAE rates were similar (mortality: 1.7% vs 3.3%; P = 0.299; MAE: 3.9% vs 5.2%; P = 0.562). CONCLUSIONS: In this first large propensity score-matched comparison, procedural success rates and MAE did not differ significantly between patients treated with the PASCAL or MitraClip valve repair system. Procedural results with less than moderate MR and no elevated transmitral gradient were more common in the PASCAL group, which might have an impact on long-term outcome.

Chronic obstructive pulmonary disease phenotypes in Turkey: the COPET study-a national, multicenter cross-sectional observational study.

BACKGROUND: While mortality rates decrease in many chronic diseases, it continues to increase in COPD. This situation has led to the need to develop new approaches such as phenotypes in the management of COPD. We aimed to investigate the distribution, characteristics and treatment preference of COPD phenotypes in Turkey. METHODS: The study was designed as a national, multicenter, observational and cross-sectional. A total of 1141 stable COPD patients were included in the analysis. RESULTS: The phenotype distribution was as follows: 55.7% nonexacerbators (NON-AE), 25.6% frequent exacerbators without chronic bronchitis (AE NON-CB), 13.9% frequent exacerbators with chronic bronchitis (AE-CB), and 4.8% with asthma and COPD overlap (ACO). The FEV1 values were significantly higher in the ACO and NON-AE than in the AE-CB and AE NON-CB (p < 0.001). The symptom scores, ADO (age, dyspnoea and FEV1 ) index and the rates of exacerbations were significantly higher in the AE-CB and AE NON-CB phenotypes than in the ACO and NON-AE phenotypes (p < 0.001). Treatment preference in patients with COPD was statistically different among the phenotypes (p < 0.001). Subgroup analysis was performed in terms of emphysema, chronic bronchitis and ACO phenotypes of 1107 patients who had thoracic computed tomography. A total of 202 patients had more than one phenotypic trait, and 149 patients showed no features of a specific phenotype. DISCUSSION: Most of the phenotype models have tried to classify the patient into a certain phenotype so far. However, we observed that some of the patients with COPD had two or more phenotypes together. Therefore, rather than determining which phenotype the patients are classified in, searching for the phenotypic traits of each patient may enable more effective and individualized treatment.

Transcatheter Edge-to-Edge Repair for Atrial Secondary Mitral Regurgitation.

BACKGROUND: Atrial secondary mitral regurgitation (ASMR) is a subtype of SMR that has a poor prognosis, and thus far, evidence of the therapeutic options for the management of ASMR is limited. OBJECTIVES: This study aimed to investigate the effectiveness of transcatheter edge-to-edge repair (TEER) for ASMR. METHODS: The study retrospectively analyzed consecutive patients who underwent MitraClip at the Heart Center Bonn. ASMR was defined as cases that met all of the following criteria: 1) normal mitral leaflets without organic disorder; 2) left ventricular ejection fraction >50%; and 3) absence of LV enlargement and segmental abnormality. The primary outcome measure was MR reduction to ≤1+, and its predictors were explored in a logistic regression analysis. RESULTS: Among 415 patients with SMR, 118 patients met the criteria for ASMR (mean age 80 ± 8 years, 39.8% male). The technical success rate was 94.1%, and MR reduction to ≤1+ after TEER was achieved in 94 (79.7%) patients with ASMR. The in-hospital mortality rate was 2.5%. In multivariable logistic analysis, a large left atrial volume index and low leaflet-to-annulus index were associated with a lower incidence of MR reduction to ≤1+ after TEER for ASMR. In addition, the use of a newer generation of the MitraClip systems (NTR/XTR or G4 systems) was associated with a higher incidence of MR reduction to ≤1+. CONCLUSIONS: TEER is a safe and feasible therapeutic option for patients with ASMR. Assessments of left atrial volume index and leaflet-to-annulus index may assist with patient selection for TEER in patients with ASMR.

Acute Kidney Injury Following Tricuspid Transcatheter Edge-to-Edge Repair.

BACKGROUND: Little is known about the incidence and clinical relevance of postprocedural acute kidney injury (AKI) in patients undergoing transcatheter edge-to-edge repair (TEER) for tricuspid regurgitation (TR). OBJECTIVES: The aim of this study was to investigate the prognostic impact of postprocedural AKI following TEER for TR. METHODS: Two hundred sixty-eight patients who underwent TEER for TR at 2 centers were retrospectively analyzed. Postprocedural AKI was defined as an increase in serum creatinine of ≥0.3 mg/dL within 48 hours or ≥50% within 7 days after the procedure compared with baseline. The association between AKI and the composite outcome, consisting of all-cause mortality and rehospitalization for heart failure within 1 year after the procedure, was determined. RESULTS: The mean age of the patients was 79.0 ± 6.8 years, and 43.3% were men. Postprocedural AKI occurred in 42 patients (15.7%). Age, male sex, an estimated glomerular filtration rate of <60 mL/min/1.73 m2, and absence of procedural success were associated with the occurrence of AKI. Patients with AKI had a higher incidence of in-hospital mortality than those without AKI (9.5% vs 0.9%; P = 0.006). Moreover, AKI was associated with the incidence of the composite outcome within 1 year after TEER for TR (adjusted HR: 2.39; 95% CI: 1.45-3.94; P = 0.001). CONCLUSIONS: Postprocedural AKI occurred in 15.7% of patients undergoing TEER for TR, despite the absence of iodinated contrast agents, which was associated with worse clinical outcomes. These findings highlight the clinical impact of AKI following TEER for TR and should help in identifying patients at high risk for AKI.

3D-speckle-tracking echocardiography correlates with cardiovascular magnetic resonance imaging diagnosis of acute myocarditis - An observational study.

Background: The diagnostic importance of three-dimensional (3D) speckle-tracking strain-imaging echocardiography in patients with acute myocarditis remains unclear. The aim of this study was to test the diagnostic performance of 3D-speckle-tracking echocardiography compared to CMR (cardiovascular magnetic resonance imaging) for the diagnosis of acute myocarditis. Methods and results: 45 patients with clinically suspected myocarditis were enrolled in our study (29% female, mean age: 43.9 ± 16.3 years, peak troponin I level: 1.38 ± 3.51 ng/ml). 3D full-volume echocardiographic images were obtained and offline 2D as well as 3D speckle-tracking analysis of regional and global LV deformation was performed. All patients received CMR scans and myocarditis was diagnosed in 29 subjects based on original Lake-Louise criteria. The 16 patients, in whom myocarditis was excluded by CMR, served as controls. Regional changes in myocardial texture (diagnosed by CMR) were significantly associated with regional impairment of circumferential, longitudinal, and radial strain, as well as regional 3D displacement and total 3D strain. Interestingly, the 2D and 3D global longitudinal strain (GLS) showed higher diagnostic performance than well-known parameters associated with myocarditis, such as LVEF (as obtained by echocardiography and CMR) and LVEDV (as obtained by CMR). Conclusions: In this study, we examined the use of 3D-speckle-tracking echocardiography in patients with acute myocarditis. Global longitudinal strain was significantly impaired in patients with acute myocarditis and correlated with CMR findings. Therefore, 3D echocardiography could become a useful diagnostic tool in the primary diagnosis of myocarditis.
