Background: In recent years, the use of transcatheter valve-in-valve implantation in the mitral position (TMVI) for the treatment of mitral valve pathology following ring or bioprosthetic implantation has emerged as a less invasive option in comparison to repeated mitral valve surgery (RMVS). We aimed to compare the early and mid-term results of these two strategies. Method: We retrospectively analyzed all patients who underwent a mitral intervention in our institution between 2005 and 2022. Applying the exclusion criteria, 41 subjects were analyzed: 23 underwent RMVS, while 18 underwent a TMVI. The time-dependency treatment effect was approached using a landmark analysis, applying the Kaplan–Meier analysis at different time points. Results: The two study groups were comparable in terms of age (p = 0.18), gender (p = 0.78), body surface area (p = 0.33), and EuroSCORE II (p = 0.06). No patients died perioperatively or had a stroke. Two patients in each group died within the first 30 days following the procedure (RMVS 8.3% vs. TMVI 11.1%; p = 0.75). Eighteen patients had died at follow-up; two underwent re-intervention on their mitral valve (one in each group). The mean survival was not statistically different between groups (RMVS 8 ± 1.1 years, 95% CI 5.8–10.2, vs. TMVI 4.79 ± 0.82 years, 95% CI 3.1–6.4; log-rank = 0.087). A landmark analysis of survival after four years showed significantly worse survival for patients in the TMVI group in comparison with those treated surgically (log-rank = 0.047). Conclusions: TMVI and RMVS are both effective strategies with similar short-term outcomes. However, patients in the TMVI group showed a significantly lower survival rate after four years.

Tricuspid regurgitation (TR) is frequently encountered in clinical practice. It is classified into primary TR (organic), which accounts for a minority of cases; and into secondary TR (functional), which has a higher prevalence. Although it can be asymptomatic for a long time, TR causes right ventricle dysfunction and increases hospitalizations for heart failure and mortality. In most patients with severe, isolated TR, surgery is not indicated due to the high surgical risk. In the last 10 years, transcatheter tricuspid valve repair became feasible with the following good results: reduction in TR severity, reverse remodeling of the right heart chambers, improvement in symptoms and reduction in hospitalization time. This paper presents the main transcatheter techniques and data from relevant trials that used these techniques, focusing on patient characteristics that define eligibility and high probability of repair. Information is provided regarding the observed benefits and the complications. [ABSTRACT FROM AUTHOR]

Introduction: Clinically significant severe tricuspid regurgitation (TR) is a common untreated pathology associated with increased mortality. Even though surgical valve replacement has been the mainstay option, transcatheter intervention is a novel and potentially effective tool. To the best of our knowledge, this is the first systematic review that assessed and compared clinical and echocardiographic outcomes of coaptation and annuloplasty devices in patients with clinically significant TR. Methods: PubMed, the Cochrane Central Register of Controlled Trials, and EMBASE were searched for articles published from August 2016 until February 2023. Primary endpoints were technical and procedural successes. Secondary endpoints were TR grade, NYHA, change in 6 min walk distance (6MWD), and echocardiographic parameters at 30-day follow-up. Results: We included thirty-eight studies consisting of 2273 patients with severe symptomatic TR (NYHA III-IV 77% and severe/massive/torrential TR 83.3%) and high surgical risk (mean EUROSCORE of 7.54). The technical success for the annuloplasty devices was 96.7% and for the coaptation device was 94.8%. The procedural success for the annuloplasty devices was 64.6% and for the coaptation device was 81.4%. The 6MWD increased by 17 m for the coaptation devices and increased by 44 m after 30 days for the annuloplasty devices. A reduction in TR grade to <2 was seen in 70% of patients with coaptation and 59% of patients with annuloplasty devices. Conclusions: Transcatheter tricuspid valve intervention appears to be feasible and is associated with favorable outcomes. [ABSTRACT FROM AUTHOR]

Background/Objectives: The incidence and prevalence of tricuspid regurgitation (TR) are increasing worldwide. "Traditional" drug therapy with diuretics is often ineffective and the identification of new strategies, including non-pharmacological ones, is an urgent need. The aim of this study was to summarize the results on the efficacy and safety of Cardioband, one of the few approved transcatheter tricuspid valve repair systems, in patients with TR. Methods: Three databases (Medline, Scopus, and CENTRAL) were searched to identify clinical trials and observational studies on the efficacy (primary outcome) and safety (secondary outcome) of Cardioband. A random-effects meta-analysis was performed with R software (version 4.3.3). Survival and freedom from heart failure (HF) hospitalization were estimated with the method of reconstructing individual patient data from Kaplan–Meier curves (IPDfromKM). Results: Eleven studies were included in this systematic review and meta-analysis. Cardioband significantly reduced annulus diameter (−9.31 mm [95% Confidence Interval, CI: −11.47; −7.15]), vena contracta (−6.41 mm [95% CI: −8.34; −4.49]), and effective regurgitant orifice area (EROA) (−0.50 cm2 [95% CI: −0.72; −0.28]) in patients with TR. Cardioband reduced the severity of TR and the extent of heart failure in 91% [95% CI: 85; 97] and 63% [95% CI: 52–75] of patients, respectively. Finally, Cardioband implantation was associated with prolonged survival and freedom from HF hospitalization (80.1% and 57.8% at 24 months, respectively). Conclusions: This study demonstrates that Cardioband implantation leads to cardiac remodeling and mechanical improvements, reduces the severity of TR, and improves quality of life. Therefore, Cardioband is an effective option for the non-pharmacological treatment of TR. [ABSTRACT FROM AUTHOR]

The growing awareness of tricuspid regurgitation (TR) and the fast-expanding array of devices aiming to percutaneously repair or replace the tricuspid valve have underscored the central role of multi-modality imaging in comprehensively assessing the anatomical and functional characteristics of TR. Accurate phenotyping of TR, the right heart, and pulmonary vasculature via echocardiography, computed tomography, and, occasionally, cardiovascular magnetic resonance and right heart catheterization is deemed crucial in choosing the most suitable treatment strategy for each patient and achieving procedural success. In the first part of the present review, key imaging factors for patient selection will be discussed. In the ensuing sections, an overview of the most commonly used, commercially available systems for transcatheter repair/replacement will be presented, along with their respective selection criteria and information on intraprocedural imaging guidance; these are edge-to-edge repair, orthotopic and heterotopic replacement, and valve-in-valve procedures.

Severe tricuspid regurgitation (TR) is a pathological condition associated with worse cardiovascular outcomes. In the vicious cycle of right ventricular compensation and maladaptation to TR, the development of right ventricle (RV) dysfunction has significant prognostic implications, especially in patients undergoing surgical or percutaneous treatments. Indeed, RV dysfunction is associated with increased operative morbidity and mortality in both surgical and percutaneously treated patients. In this context, the identification of clinical or subtle right ventricle dysfunction plays a critical role inpatient selection and timing of surgical or percutaneous tricuspid valve intervention. However, in the presence of severe TR, evaluation of RV function is challenging, given the increase in preload that may lead to an overestimation of systolic function for the Frank–Starling law, reduced reliability of pulmonary artery pressure estimation, the sensitivity of RV to afterload that may result in afterload mismatch after treatment. Consequently, conventional echocardiographic indices have some limitations, and the use of speckle tracking for right ventricular free wall longitudinal strain (RV-FWLS) analysis and the use of 3D echocardiography for RV volumes and ejection fraction estimation are showing promising data. Cardiac magnetic resonance (CMR) represents the gold standards for volumes and ejection fraction evaluation and may add further prognostic information. Finally, cardiac computer tomography (CCT) provides measurements of RV and annulus dimensions that are particularly useful in the transcatheter field. Identification of subtle RV dysfunction may need, therefore, more than one imaging technique, which will lead to tip the balance between medical therapy and early intervention towards the latter before disease progression. Therefore, the aim of this review is to describe the main imaging techniques, providing a comprehensive assessment of their role in RV function evaluation in the presence of severe TR.

Tricuspid regurgitation (TR) is an intricate disorder that has a negative outlook, while surgical treatment is linked to increased mortality. Primary TR occurs due to a structural defect in the tricuspid valve (TV), while secondary TR is a more prevalent condition often associated with pulmonary hypertension, heart failure, and atrial fibrillation. The use of specific surgical procedures to improve TR is limited in everyday clinical practice due to the heightened surgical risk and delayed patient presentation. The development of other transcatheter heart valve procedures has led to a significant increase in transcatheter TV operations, which can be attributed to certain technological advancements. This review aims to provide an updated overview of transcatheter TV procedures, available alternative therapies, and standards for patient selection. It will also highlight the current state of development in this field, which is characterized by rapid progress and numerous ongoing clinical trials. [ABSTRACT FROM AUTHOR]

The emergence of percutaneous treatment options provides novel therapeutic alternatives for older and feeble patients who are at high risk for any surgical procedure. The purpose of our review was to offer an up-to-date analysis of the rapidly expanding field of percutaneous technologies for mitral, tricuspid, and pulmonary procedures. Edge-to-edge repair is an established treatment for secondary mitral regurgitation (MR), while transcatheter mitral valve replacement is a potential and expanding option for managing both secondary and primary MR. However, additional advancements are necessary to enhance the safety and feasibility of this procedure. Transcatheter tricuspid intervention is an emerging option that was conceived after the success of transcatheter procedures in aortic and mitral valves, and it is currently still in the early stages of advancement. This can be attributed, at least in part, to the previously overlooked effect of tricuspid regurgitation on patient outcomes. The development of edge-to-edge repair represents the forefront of innovations in transcatheter procedures. There is a scarcity of data about tricuspid annuloplasty and replacement, and further study is necessary. Transcatheter mitral, tricuspid, and pulmonary procedures show prospects for the future, while their role in clinical practice has not been definitively established. [ABSTRACT FROM AUTHOR]

The echocardiographic tricuspid annular plane systolic excursion/pulmonary artery systolic pressure (TAPSE/PASP) ratio is a non-invasive surrogate of right ventricular-pulmonary arterial (RV-PA) coupling which corresponds well with the respective invasively derived index. Recently, a wealth of observational data has arisen, outlining its prognostic value in heart failure (HF) patients. To systematically appraise and quantitatively synthesize the evidence of the prognostic value of TAPSE/PASP ratio in left-sided HF regardless of etiology or left ventricular ejection fraction. A systematic literature review was conducted in electronic databases to identify studies reporting the association of TAPSE/PASP ratio with outcomes in patients with HF and, when appropriate, a random-effects meta-analysis was conducted to quantify the unadjusted and adjusted hazard ratios [(a)HRs] for all-cause death and the composite outcome of all-cause death or HF hospitalization. Eighteen studies were deemed eligible encompassing 8,699 HF patients. The applied cut-off value for RV-PA uncoupling varied substantially from 0.27 to 0.58 mm/mmHg, and in most studies values lower than the applied cutoff conveyed dismal prognosis. Eleven studies reported appropriate data for meta-analysis. TAPSE/PASP reduction by 1 mm/mmHg was independently associated with all-cause death (pooled aHR=1.32 [1.06-1.65]; p=0.01; I2=56%) and the composite outcome (pooled aHR=3.48 [1.67-7.25]; p<0.001; I2=0%). When a TAPSE/PASP cutoff value of 0.36 mm/mmHg was applied it yielded independent association with all-cause death (pooled aHR=2.84 [2.22-3.64]; p<0.001; I2=82%). RV-PA coupling assessed by echocardiographic TAPSE/PASP ratio appears to be an independent outcome predictor for HF patients. [ABSTRACT FROM AUTHOR]

Background: Transcatheter repair emerges as a treatment option in patients with tricuspid regurgitation (TR) and high surgical risk. Aims: This study aimed to compare leaflet-based and annuloplasty-based transcatheter repair in patients with TR. Methods: In a retrospective analysis consecutive patients undergoing either transcatheter edge-to-edge repair (TEER) or direct annuloplasty (AP) for relevant TR at 2 centers were compared with respect to baseline characteristics, procedural efficacy and safety (death, myocardial infarction, procedure or device-related cardiothoracic surgery, or stroke at 30 days). Results: 161 patients (57% female, median age 79 [75–82] years) with comparable clinical baseline characteristics in the TEER (n = 87) and AP (n = 74) group were examined. Baseline TR grade was significantly less severe in the TEER compared to the AP group (torrential 9.2 vs. 31.1%, p = 0.001). Technical success and improvement of TR grades were not significantly different across groups. In analysis matched for baseline TR severity, reduction of TR grade to less than moderate was significantly more common in the AP group (47.8 vs. 26.1%, p = 0.031). Major or more severe bleeding occurred in 9.2% of TEER and 20.3% of AP patients (p = 0.049) without any fatal bleedings. Major adverse events (MAE) were similar across groups with four patients (4.7%) in the TEER group and five patients (6.9%) in the AP group (p = 0.733) and 6-month survival did not differ significantly. Conclusions: Differences observed between patients treated with TEER and AP provide first evidence for tailoring distinct transcatheter treatment techniques to individual patient characteristics.

Tricuspid regurgitation (TR) is a highly prevalent valvular heart disease that has been long overlooked, but lately its independent association with adverse cardiovascular outcomes was recognized. The time point to intervene and repair the tricuspid valve is defined by the right ventricular (RV) dilation and dysfunction that comes up at a later stage. While guidelines favor tricuspid valve repair before severe RV dysfunction ensues, the definition of RV dysfunction in a universal manner remains vague. As a result, the candidates for transcatheter or surgical TR procedures are often referred late, when advanced RV dysfunction is established, and any derived procedural survival benefit is attenuated. Thus, it is of paramount importance to establish a universal means of RV function assessment in patients with TR. Conventional echocardiographic indices of RV function routinely applied have fundamental flaws that limit the precise characterization of RV performance. More recently, novel echocardiographic indices such as strain via speckle-tracking have emerged, demonstrating promising results in the identification of early RV damage. Additionally, evidence of the role of alternative imaging modalities such as cardiac computed tomography and cardiac magnetic resonance, for RV functional assessment in TR, has recently arisen. This review provides a systematic appraisal of traditional and novel multimodality indices of RV function in severe TR and aims to refine RV function assessment, designate future directions, and ultimately, to improve the outcome of patients suffering from severe TR.

Right ventricular function strongly predicts cardiac death and adverse cardiac events in patients with cardiac diseases. However, the accurate right ventricular assessment by two-dimensional echocardiography is limited due to its complex anatomy, shape, and load dependence. Advances in cardiac imaging and three-dimensional echocardiography provided more reliable information on right ventricular volumes and function without geometrical assumptions. Furthermore, the pathophysiology of right ventricular dysfunction and tricuspid regurgitation is frequently connected. Three-dimensional echocardiography allows a more in-depth structural and functional evaluation of the tricuspid valve. Understanding the anatomy and pathophysiology of the right side of the heart may help in diagnosing and managing the disease by using reliable imaging tools. The present review describes the challenging echocardiographic assessment of the right ventricle and tricuspid valve apparatus in clinical practice with a focus on three-dimensional echocardiography.

Tricuspid regurgitation (TR) is a common valvular pathology, estimated to affect 1.6 million people in the United States alone. Even though guidelines recommend either medical therapy or surgical treatment for TR, the misconception of TR as a benign disease along with the high mortality rates of surgical intervention led to undertreating this disease and commonly describing it as a "forgotten" valve. Recently, the development of transcatheter interventions for TR show promising potential for use in the clinical setting. There are currently few approved and numerous tested percutaneously delivered devices, which can be categorized, based on their mechanism of action, to either valve repair or valve replacement procedures. Both procedures were tested in clinical trials and show an echocardiographic reduction in TR sustained for at least 1 year after the procedure, as well as symptom relief and functional improvement of the patients. Device selection should be personalized, taking into consideration the anatomy of each valve and the available options at each heart center. Moreover, appropriate patient selection and timing of the procedure are also crucial for the success of the procedure. In this review, we analyze the clinical trials available for all devices currently approved or tested, aiming to provide a comprehensive summary of the most recent evidence in the field of transcatheter TR interventions.

Background: Redo mitral valve surgery is the standard of care for failed mitral bioprostheses or recurrence of mitral regurgitation after repair. Nonetheless, catheter-based valve-in-valve (ViV) or valve-in-ring (ViR) procedures have increasingly become viable alternatives in high-risk subpopulations. Despite reported good initial results, little is known about longer-term outcomes. Here, we report the long-term outcomes of transcatheter mitral ViV and ViR procedures. Methods: All consecutive patients (n = 54) undergoing transcatheter mitral ViV or ViR procedures for failed bioprostheses or recurring regurgitation after mitral repair in the time period between 2011 and 2021 were retrospectively enrolled. The mean age was 76.5 ± 6.5 years, and 30 (55.6%) of the patients were male. The procedures were done using a commercially available balloon-expandable transcatheter heart valve. Clinical and echocardiographic follow-up data were obtained from the hospital's database and analyzed. Follow-up reached up to 9.9 years with a total of 164.3 patient-years. Results: A total 25 patients received a ViV and 29 patients a ViR procedure. Both groups were at high surgical risk with an STS-PROM of 5.9 ± 3.7% in ViV and 8.7 ± 9.0% in ViR patients (p < 0.01). The procedures themselves were mainly uneventful with no intraoperative deaths and a low conversion rate (n = 2/54; 3.7%). VARC-2 procedural success was low (ViV 20.0% and ViR 10.3%; p = 0.45), which was either driven by high rates of transvalvular pressure gradients ">5 mmHg" (ViV 92.0% and ViR 27.6%; p < 0.01) or residual regurgitation ">trace" (ViV 28.0% and ViR 82.7%; p < 0.01). ICU-stay was prolonged in both groups (ViV 3.8 ± 6.8 days and ViR 4.3 ± 6.3 days; p = 0.96) with acceptable hospital stay (ViV 9.9 ± 5.9 days and ViR 13.5 ± 8.0 days; p = 0.13). Despite 30-day mortality being acceptable (ViV 4.0% and ViR 6.9%; p = 1.00), the mean posthospital survival time was disappointingly low (ViV 3.9 ± 2.6 years and ViR 2.3 ± 2.7 years; p < 0.01). Overall survival in the entire group was 33.3%. Cardiac reasons for death were frequent in both groups (ViV 38.5% and ViR 52.2%). Cox-regression analysis identified ViR procedures as a predictor of mortality (HR 2.36, CI 1.19–4.67, p = 0.01). Conclusions: Despite acceptable immediate outcomes in this high-risk subpopulation, long-term results are discouraging. Transvalvular pressure gradients as well as residual regurgitations remained drawbacks in this real-world population. The indication for catheter-based mitral ViV or ViR procedures rather than conventional redo-surgery or conservative treatment must be thoughtfully considered. [ABSTRACT FROM AUTHOR]

Advanced heart failure is often accompanied by perturbations in cardiac chamber or valve geometries which result in worsening cardiac function and hemodynamics. Once limited to surgical procedures, recent developments in minimally invasive percutaneous techniques have demonstrated efficacy in patients with both reduced and preserved ejection fraction who are at an elevated surgical risk for perioperative events. This review highlights a subset of the interventions available in clinical practice or in development for the treatment of these valvular and structural alterations. [ABSTRACT FROM AUTHOR]

Background: Transcatheter mitral valve implantation (TMVI) with self-expanding (SAV) or balloon-expandable (BAV) valves are rising as promising treatment options for high-risk patients with symptomatic mitral valve (MVD) disease unsuitable for alternative treatment options. Aims: The aim of this study was to examine the clinical, procedural and outcome parameters of patients undergoing SAV or BAV for MVD. Methods: In this observational and single-center case series, fifteen consecutive patients treated with the Tendyne Mitral Valve System (SAV) and thirty-one patients treated with SAPIEN prosthesis (BAV) were included. Results: The patients (aged 78 years [interquartile range (IQR): 65.5 to 83.1 years], 41% women, EuroSCORE II 10.3% [IQR: 5.5 to 17.0%] were similar regarding baseline characteristics, despite a higher rate of prior heart valve surgery and prevalence of MV stenosis in the SAV-group. At discharge, the SAV-group had a mean transvalvular gradient of 4.2 mmHg, whereas the BAV-group had a mean transvalvular gradient of 6.2 mmHg. None or trace paravalvular leakage (PVL) was assessed in 85% in SAV-group and 80% in the BAV-group. 320 day all-cause and cardiac mortality rates were comparable in both groups (SAV: 26.7% vs BAV: 20%, p = 0.60). Four deaths occurred early in the SAV-group until 32 days of follow-up. Conclusions: In high-risk patients with MVD, TMVI presents a promising treatment option with encouraging mid-term outcomes and good valve durability. TMVI either with BAV or SAV may be developed to an established treatment option. [ABSTRACT FROM AUTHOR]

Heart failure is becoming the central problem in cardiology. Its recognition, differential diagnosis, and the monitoring of therapy are intimately coupled with cardiac imaging. Cardiac imaging has witnessed an explosive growth and differentiation, with echocardiography continuing as the first diagnostic step; the echocardiographic exam itself has become considerably more complex than in the last century, with the assessment of diastolic left ventricular function and strain imaging contributing important information, especially in heart failure. Very often, however, echocardiography can only describe the fact of functional impairment and morphologic remodeling, whereas further clarification of the underlying disease, such as cardiomyopathy, myocarditis, storage diseases, sarcoidosis, and others, remains elusive. Here, cardiovascular magnetic resonance and perfusion imaging should be used judiciously to arrive as often as possible at a clear diagnosis which ideally enables specific therapy.

Background: The natural history of tricuspid valve regurgitation (TR) is characterized by poor prognosis and high in-hospital mortality when treated with isolated surgery. We report the preliminary echocardiographic and procedural results of a prospective cohort of symptomatic patients with high to prohibitive surgical risk and at least severe TR who underwent transcatheter edge-to-edge repair through the TriClipTM system. Methods: From June 2020 to March 2022, 27 consecutive patients were screened, and 13 underwent transcatheter TriClipTM repair. In-hospital, 30-day and six-month clinical and echocardiographic outcomes were collected. Results: Nine patients had severe, three massive and one baseline torrential TR. Sustained TR reduction of ≥1 grade was achieved in all patients, of which 90% reached a moderate TR or less. On transthoracic echocardiographic examination, there were significant reductions in vena contracta width (p < 0.001), effective regurgitant orifice area (p < 0.001) and regurgitant volume (p < 0.001) between baseline and hospital discharge. We also observed a significant reduction in tricuspid annulus diameter (p < 0.001), right ventricular basal diameter (p = 0.001) and right atrial area (p = 0.026). Conclusion: Treatment with the edge-to-edge TriClip device is safe and effective. The resulting echocardiographic improvements indicate tricuspid valve leaflet approximation does not just significantly reduce the grade of TR but also affects adjacent structures and improves right ventricular afterload adaptation.

Background: Re-operative mitral valve (MV) replacement is a high-risk procedure, therefore, transcatheter MV replacement (TMVR) is a promising therapeutic option.Aim: In this study, we aimed to evaluate the feasibility and safety of TMVR in patients with high surgical risk with degenerated mitral bioprostheses (TMViV), failed surgical rings (TMViR), and mitral annular calcification (TMViMAC).Methods: This is a retrospective cohort study that enrolled patients with high surgical risk who underwent TMVR from February 2017 to September 2020. The TMVR procedure was performed using Edwards SAPIEN-3 valves through the transseptal approach.Results: Sixty-four patients aged 62.7 ± 16.1 years with an STS score of 9.2 ± 3.7% underwent TMVR [35 (55%) TMViV, 16 (25%) TMViR, and 13 (20%) TMViMAC]. Mitral stenosis was more frequent in TMViV, mitral regurgitation was more frequent in TMViR, and combined mitral stenosis and regurgitation were more frequent in TMViMAC (P < 0.05). The MV gradient was 14.3 ± 5.3 mmHg and the MV area was 1.5±0.6 cm2. The 29 mm valve was frequently used in TMViV and TMViMAC, while the 23 mm valve was frequently used in TMViR (P=0.003 ∗ ). The procedural and fluoroscopy times were 58.7 ± 8.9 and 41.1 ± 8.2 minutes, respectively. Technical success was reported in 62 (98.4%) patients; 1 TMViR patient experienced valve embolization and salvage surgery, and 1 TMViMAC patient experienced slight valve malposition. At 3 months, 2 (3.1%) patients showed valve thrombosis (treated with anticoagulation), and 1 (1.6%) patient developed a paravalvular leak (underwent surgical MV replacement). At 6 months, 3 (4.7%) patients showed valve degeneration (underwent surgical MV replacement). Throughout follow-up, no patient exhibited mortality.Conclusions: TMVR is a feasible and safe approach in patients with high surgical risk. TMViV and TMViR are reasonable as the first treatment approaches, and TMViMAC seems encouraging. [ABSTRACT FROM AUTHOR]

Aim: The impact of chronic kidney disease (CKD) on patient-related outcomes in patients with tricuspid regurgitation (TR) is well known. However, the impact of the progression of CKD in patients with TR and potentially modifiable risk factors of progressing CKD is unknown. Methods: 444 consecutive adult patients with TR and CKD stage 1–4 admitted in an inpatient setting between January 2010 and December 2017 were included. During a median follow-up of two years, eGFR and survival status were collected. Independent risk factors for CKD progression and all-cause mortality were determined. Patient survival statuses were grouped according to different combinations of the presence or absence of CKD progression and the TR grade. Results: Progression of CKD (OR 2.38 (95% confidence interval 1.30–4.35), p = 0.005), the grade of TR (OR 2.38 (1.41–4.00), p = 0.001) and mitral regurgitation (OR 1.72 (1.20–2.46), p = 0.003) were independent risk factors for all-cause mortality. Haemoglobin at admission (OR 0.80 (0.65–0.99), p = 0.043) and the presence of type 2 diabetes (OR 1.67 (1.02–2.73), p = 0.042) were independent risk factors for CKD progression. The combination of the status of CKD progression and the TR grade showed a stepwise pattern for all-cause mortality (p < 0.001). Patients with CKD progression and TR grade 1 had comparable all-cause mortality with patients without CKD progression but with TR grade 2 or 3. Even in patients with TR grade 1, the risk for all-cause mortality doubled if CKD progression occurred (OR 2.49 (95% CI 1.38–4.47), p = 0.002). Conclusion: CKD progression appears to be a risk factor for all-cause mortality in patients with TR. Anaemia and diabetes are potential modifiers of CKD progression. [ABSTRACT FROM AUTHOR]

Dynamic imaging of heart valves and specifically prosthetic valves is a central benefit of echocardiography. Most bioprosthetic heart valves degenerate over a given time and hence require repeat valve replacement which carries a significant risk of morbidity and mortality. Reoperation is the standard of care and may still be required after the first successful surgery due to complications disrupting either mechanical or bioprosthetic valves. Such complications can be delayed or even prevented if optimal prosthesis selection is individualized according to patients' medical and postimplantation follow-up. We present the case of an 84-year-old woman where an open-heart valve-in-valve approach, implanting a mechanical valve in a failed bioprosthetic valve, produced a unique image on transthoracic echocardiography which needs to be recognized by imagers for appropriate patient diagnosis and management.
