ABSTRACT
BACKGROUND AND AIMS: Mitral valve surgery and, more recently, mitral transcatheter edge-to-edge repair (TEER) are the two treatments of severe mitral regurgitation in eligible patients. Clinical comparison of both therapies remains limited by the number of patients analysed. The objective of this study was to analyse the outcomes of mitral TEER vs. isolated mitral valve surgery at a nationwide level in France. METHODS: Based on the French administrative hospital discharge database, the study collected information for all consecutive patients treated for mitral regurgitation with isolated TEER or isolated mitral valve surgery between 2012 and 2022. Propensity score matching was used for the analysis of outcomes. RESULTS: A total of 57 030 patients were found in the database. After matching on baseline characteristics, 2160 patients were analysed in each arm. At 3-year follow-up, TEER was associated with significantly lower incidence of cardiovascular death (hazard ratio 0.685, 95% confidence interval 0.563-0.832; P = .0001), pacemaker implantation, and stroke. Non-cardiovascular death (hazard ratio 1.562, 95% confidence interval 1.238-1.971; P = .0002), recurrent pulmonary oedema, and cardiac arrest were more frequent after TEER. No significant differences between the two groups were observed regarding all-cause death (hazard ratio 0.967, 95% confidence interval 0.835-1.118; P = .65), endocarditis, major bleeding, atrial fibrillation, and myocardial infarction. CONCLUSIONS: Our results suggest that TEER for severe mitral regurgitation was associated with lower cardiovascular mortality than mitral surgery at long-term follow-up. Pacemaker implantation and stroke were less frequently observed after TEER.

BACKGROUND AND AIMS: Benefit of tricuspid regurgitation (TR) correction and timing of intervention are unclear. This study aimed to compare survival rates after surgical or transcatheter intervention to conservative management according to a TR clinical stage as assessed using the TRI-SCORE. METHODS: A total of 2,413 patients with severe isolated functional TR were enrolled in TRIGISTRY (1217 conservatively managed, 551 isolated tricuspid valve surgery, and 645 transcatheter valve repair). The primary endpoint was survival at 2 years. RESULTS: The TRI-SCORE was low (≤3) in 32%, intermediate (4-5) in 33%, and high (≥6) in 35%. A successful correction was achieved in 97% and 65% of patients in the surgical and transcatheter groups, respectively. Survival rates decreased with the TRI-SCORE in the three treatment groups (all P < .0001). In the low TRI-SCORE category, survival rates were higher in the surgical and transcatheter groups than in the conservative management group (93%, 87%, and 79%, respectively, P = .0002). In the intermediate category, no significant difference between groups was observed overall (80%, 71%, and 71%, respectively, P = .13) but benefit of the intervention became significant when the analysis was restricted to patients with successful correction (80%, 81%, and 71%, respectively, P = .009). In the high TRI-SCORE category, survival was not different to conservative management in the surgical and successful repair group (61% and 68% vs 58%, P = .26 and P = .18 respectively). CONCLUSIONS: Survival progressively decreased with the TRI-SCORE irrespective of treatment modality. Compared to conservative management, an early and successful surgical or transcatheter intervention improved 2-year survival in patients at low and, to a lower extent, intermediate TRI-SCORE, while no benefit was observed in the high TRI-SCORE category.

BACKGROUND: Type 2 diabetes (T2D) is a frequent comorbidity encountered in patients with severe aortic stenosis (AS), leading to an adverse left ventricular (LV) remodeling and dysfunction. Metabolic alterations have been suggested as contributors of the deleterious effect of T2D on LV remodeling and function in patients with severe AS, but so far, the underlying mechanisms remain unclear. Mitochondria play a central role in the regulation of cardiac energy metabolism. OBJECTIVES: We aimed to explore the mitochondrial alterations associated with the deleterious effect of T2D on LV remodeling and function in patients with AS, preserved ejection fraction, and no additional heart disease. METHODS: We combined an in-depth clinical, biological and echocardiography phenotype of patients with severe AS, with (n = 34) or without (n = 50) T2D, referred for a valve replacement, with transcriptomic and histological analyses of an intra-operative myocardial LV biopsy. RESULTS: T2D patients had similar AS severity but displayed worse cardiac remodeling, systolic and diastolic function than non-diabetics. RNAseq analysis identified 1029 significantly differentially expressed genes. Functional enrichment analysis revealed several T2D-specific upregulated pathways despite comorbidity adjustment, gathering regulation of inflammation, extracellular matrix organization, endothelial function/angiogenesis, and adaptation to cardiac hypertrophy. Downregulated gene sets independently associated with T2D were related to mitochondrial respiratory chain organization/function and mitochondrial organization. Generation of causal networks suggested a reduced Ca2+ signaling up to the mitochondria, with the measured gene remodeling of the mitochondrial Ca2+ uniporter in favor of enhanced uptake. Histological analyses supported a greater cardiomyocyte hypertrophy and a decreased proximity between the mitochondrial VDAC porin and the reticular IP3-receptor in T2D. CONCLUSIONS: Our data support a crucial role for mitochondrial Ca2+ signaling in T2D-induced cardiac dysfunction in severe AS patients, from a structural reticulum-mitochondria Ca2+ uncoupling to a mitochondrial gene remodeling. Thus, our findings open a new therapeutic avenue to be tested in animal models and further human cardiac biopsies in order to propose new treatments for T2D patients suffering from AS.

OBJECTIVES: To analyze the incidence, clinical impact on survival, and risk factors of lower limb ischemia (LLI) of surgical peripheral femoral venoarterial extracorporeal membrane oxygenation (VA ECMO) in the current era. DESIGN: A retrospective analysis of the authors' institutional database of VA ECMO was performed. Patients were divided into 2 groups according to the occurrence of LLI. The primary endpoint was survival to hospital discharge. Risk factors of LLI were searched with multivariate analyses. SETTING: University hospital. PARTICIPANTS: Adult patients receiving peripheral VA ECMO for refractory cardiogenic shock and cardiac arrest. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: From January 2018 to December 2021, 188 patients (mean age: 52.0 ± 14.1 years; 63.8% male, 36.2% female) received peripheral VA ECMO. Male sex was more prevalent in the group without LLI (65.9% v 33.3%; p = 0.031). Twelve (6.4%) patients developed LLI during VA ECMO support (n = 6) or after VA ECMO removal (n = 6). Survival to hospital discharge was not statistically different between patients with and without LLI (50.0% v 48.3%; p = 0.571). Female sex patients were at increased risk for LLI (odds ratio 4.38, 95% CI 1.21-15.81; p = 0.024). CONCLUSIONS: Peripheral femoral VA ECMO through a surgical approach is associated with a low LLI rate, which does not increase the risk of in-hospital mortality. The female sex is an independent risk factor for LLI.

AIMS: Isolated tricuspid valve surgery (ITVS) is considered to be a high-risk procedure, but in-hospital mortality is markedly variable. This study sought to develop a dedicated risk score model to predict the outcome of patients after ITVS for severe tricuspid regurgitation (TR). METHODS AND RESULTS: All consecutive adult patients who underwent ITVS for severe non-congenital TR at 12 French centres between 2007 and 2017 were included. We identified 466 patients (60 ± 16 years, 49% female, functional TR in 49%). In-hospital mortality rate was 10%. We derived and internally validated a scoring system to predict in-hospital mortality using multivariable logistic regression and bootstrapping with 1000 re-samples. The final risk score ranged from 0 to 12 points and included eight parameters: age ≥70 years, New York Heart Association Class III-IV, right-sided heart failure signs, daily dose of furosemide ≥125 mg, glomerular filtration rate <30 mL/min, elevated bilirubin, left ventricular ejection fraction <60%, and moderate/severe right ventricular dysfunction. Tricuspid regurgitation mechanism was not an independent predictor of outcome. Observed and predicted in-hospital mortality rates increased from 0% to 60% and from 1% to 65%, respectively, as the score increased from 0 up to ≥9 points. Apparent and bias-corrected areas under the receiver operating characteristic curves were 0.81 and 0.75, respectively, much higher than the logistic EuroSCORE (0.67) or EuroSCORE II (0.63). CONCLUSION: We propose TRI-SCORE as a dedicated risk score model based on eight easy to ascertain parameters to inform patients and physicians regarding the risk of ITVS and guide the clinical decision-making process of patients with severe TR, especially as transcatheter therapies are emerging (www.tri-score.com).

OBJECTIVES: Report contemporary outcomes in patients included in the Mitragister registry and treated with transcatheter mitral valve implantation for failed surgical annuloplasty rings or deteriorated bioprosthesis. BACKGROUND: Midterm survival rates have been reported, but little is known about contemporary morbimortality endpoints. METHODS: The primary safety outcome was the technical success rate. The primary efficacy composite endpoint was a composite of cardiovascular mortality and heart failure hospitalizations. RESULTS: From 2016 to 2021, 102 patients (median age: 81 [74;84] years, 61% female, Euroscore II 11.0% [7.8;16.0]) undergoing valve-in-valve (ViV; n = 89) or valve-in-ring (ViR; n = 13) procedures were consecutively included. At baseline, ViR group patients had worse left ventricular ejection fraction (50% vs. 60%; p = 0.004) and more frequently severe regurgitation (46% vs. 15%; p = 0.014). The primary safety outcome was 95%: 77% and 98% in the ViR and ViV populations, respectively, (p = 0.014). At intermediate follow-up (6-12 months) clinical improvement was notable, 88% of the patients were in NYHA class ≤ II (vs. 25% at baseline; p < 0.001). At a mean follow-up of 17.1 ± 11.0 months, the primary efficacy composite reached 27%. By multivariate analysis, paravalvular leak (PVL) was the only independent predictor (hazard ratio: 2.39, 95% confidence interval: 1.08-5.29; p = 0.031) while ViR was not found statistically associated (p = 0.456). CONCLUSIONS: This study confirms the safety and efficacy of the mitral ViV procedure. ViR patients appear at higher risk of procedural complications. The presence of PVL could be associated with markedly worse midterm prognosis. Whatever the intervention, procedural strategies to reduce PVL incidence remain to be assessed to prevent latter adverse outcomes.

Ventricular septal rupture (VSR) is a serious complication of ST-elevation myocardial infarction (STEMI) and surgery is the reference treatment. We aimed at describing trends in management and mortality during the last four decades and reporting mortality predictors in these patients. We conducted a single-center retrospective study of patients sustaining a VSR from 1981 to 2020. We screened 274 patients and included 265 for analysis. The number of patients decreased over the years: 80, 88, 56, and 50 in each 10-year time span. In-hospital mortality decreased significantly since 1990 (logrank 0.007). The median age was 72.0 years IQR [66-78] and 188 patients (70.9%) were operated on. IABP was used more routinely (p < 0.0001). In-hospital mortality was assessed at 66.8% (177 patients) and main predictors of death were a time from MI to surgery < 8 days HR 2.7 IC95% [1.9-3.8] p < 0.0001, a Killip class > 2 HR 2.5 IC [1.9-3.4] p < 0.0001 and Euroscore 2 > 20 HR 2.4 IC [1.8-3.2] p < 0.0001. A "time from MI to surgery" of 8 days offers the best ability to discriminate between patients with or without mortality. The ability of "Euroscore 2 and Killip" to detect the patients most likely to wait 8 days for surgery was at 0.81 [0.73-0.89] p < 0.0001. Mortality remains high over the years. Euroscore 2, Killip class, and time from MI to surgery are the main mortality predictors. Patients with a Killip < 3 and a Euroscore < 20 should be monitored at least 8 days since MI before being referred to surgery.

OBJECTIVE: To analyze the impact of the modification of the authors' institutional protocol on outcomes after extracorporeal cardiopulmonary resuscitation (ECPR) for out-of-hospital cardiac arrest (OHCA). DESIGN: An observational analysis. The protocol complied with national recommendations. A further eligibility criterion was added since January 2015: the presence of sustained shockable rhythm at extracorporeal life support (ECLS) implantation. To assess the impact of this change, patients were divided into two groups: (1) from January 2010 to December 2014 (group A) and (2) from January 2015 to December 2019 (group B). The primary endpoint was survival to hospital discharge with good neurologic outcome. Predictors of survival were searched with multivariate analyses. SETTING: University hospital. PARTICIPANTS: Adult patients supported with ECPR for refractory OHCA. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: From January 2010 to December 2019, 85 patients had ECLS for OHCA (group A, n = 68, 80%; group B, n = 17, 20%). The mean age was 42.4 years, 78.8% were male. The rate of implantation of ECLS was significantly lower in group B (p = 0.01). Mortality during ECLS support was significantly lower (58.8 v 86.8%; p = 0.008), and the weaning rate was significantly higher (41.2 v 13.2%; p = 0.008) in group B. Survival to discharge with good neurologic outcome was significantly improved (23.5 v 4.4%; p = 0.027) in group B. A sustained shockable rhythm was the only independent predictor of survival to hospital discharge with good neurologic outcome. CONCLUSIONS: The modification of the authors' institutional protocol throughout the further criterion of sustained shockable rhythm yielded a favorable impact on outcomes after ECPR for OHCA.

The use of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has increased exponentially. Pulmonary congestion is a potentially life-threatening complication of peripheral VA-ECMO. Recently updated guidelines argue for a low threshold of left ventricular (LV) unloading. Although the optimal method of LV unloading is still a matter of debate, the percutaneous approaches became an increasingly used option over time. Here, we present a case of LV unloading with the Atrial Flow Regulator (Occlutech) in a patient supported with peripheral VA-ECMO.

BACKGROUND AND AIM OF THE STUDY: Acute cardiovascular failure remains a leading cause of death in severe poisonings. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has been increasingly used as a rescue therapeutic option for those cases refractory to optimal conventional treatment. We sought to evaluate the outcomes after VA-ECMO used for drug intoxications in a single-center experience. METHODS: We performed an observational analysis of our prospective institutional database. The primary endpoint was survival to hospital discharge. RESULTS: Between January 2007 and December 2020, 32 patients (mean age: 45.4 ± 15.8 years; 62.5% female) received VA-ECMO for drug intoxication-induced refractory cardiogenic shock (n = 25) or cardiac arrest (n = 7). Seven (21.8%) patients developed lower limb ischemia during VA-ECMO support. Twenty-six (81.2%) patients were successfully weaned after a mean VA-ECMO support of 2.9 ± 1.3 days. One (3.1%) patient died after VA-ECMO weaning for multiorgan failure and survival to hospital discharge was 78.1% (n = 25). In-hospital survivors were discharged from hospital with a good neurological status. Survival to hospital discharge was not statistically different according to sex (male = 75.0% vs. female = 80.0%; p = .535), type of intoxication (single drug = 81.8% vs. multiple drugs = 76.1%; p = .544) and location of VA-ECMO implantation (within our center = 75% vs. peripheral hospital using our Mobile Unit of Mechanical Circulatory Support = 100%; p = .352). Survival to hospital discharge was significantly lower in patients receiving VA-ECMO during on-going cardiopulmonary resuscitation (42.8% vs. 88.0%; p = .026). CONCLUSIONS: VA-ECMO appears to be a feasible therapeutic option with a satisfactory survival rate and acceptable complications rate in poisonings complicated by refractory cardiogenic shock or cardiac arrest.

Secondary (or functional) mitral regurgitation (SMR) occurs frequently in chronic heart failure (HF) with reduced left ventricular (LV) ejection fraction, resulting from LV remodelling that prevents coaptation of the valve leaflets. Secondary mitral regurgitation contributes to progression of the symptoms and signs of HF and confers worse prognosis. The management of HF patients with SMR is complex and requires timely referral to a multidisciplinary Heart Team. Optimization of pharmacological and device therapy according to guideline recommendations is crucial. Further management requires careful clinical and imaging assessment, addressing the anatomical and functional features of the mitral valve and left ventricle, overall HF status, and relevant comorbidities. Evidence concerning surgical correction of SMR is sparse and it is doubtful whether this approach improves prognosis. Transcatheter repair has emerged as a promising alternative, but the conflicting results of current randomized trials require careful interpretation. This collaborative position statement, developed by four key associations of the European Society of Cardiology-the Heart Failure Association (HFA), European Association of Percutaneous Cardiovascular Interventions (EAPCI), European Association of Cardiovascular Imaging (EACVI), and European Heart Rhythm Association (EHRA)-presents an updated practical approach to the evaluation and management of patients with HF and SMR based upon a Heart Team approach.
ABSTRACT
BACKGROUND: In patients who have chronic heart failure with reduced left ventricular ejection fraction, severe secondary mitral-valve regurgitation is associated with a poor prognosis. Whether percutaneous mitral-valve repair improves clinical outcomes in this patient population is unknown. METHODS: We randomly assigned patients who had severe secondary mitral regurgitation (defined as an effective regurgitant orifice area of >20 mm2 or a regurgitant volume of >30 ml per beat), a left ventricular ejection fraction between 15 and 40%, and symptomatic heart failure, in a 1:1 ratio, to undergo percutaneous mitral-valve repair in addition to receiving medical therapy (intervention group; 152 patients) or to receive medical therapy alone (control group; 152 patients). The primary efficacy outcome was a composite of death from any cause or unplanned hospitalization for heart failure at 12 months. RESULTS: At 12 months, the rate of the primary outcome was 54.6% (83 of 152 patients) in the intervention group and 51.3% (78 of 152 patients) in the control group (odds ratio, 1.16; 95% confidence interval [CI], 0.73 to 1.84; P=0.53). The rate of death from any cause was 24.3% (37 of 152 patients) in the intervention group and 22.4% (34 of 152 patients) in the control group (hazard ratio, 1.11; 95% CI, 0.69 to 1.77). The rate of unplanned hospitalization for heart failure was 48.7% (74 of 152 patients) in the intervention group and 47.4% (72 of 152 patients) in the control group (hazard ratio, 1.13; 95% CI, 0.81 to 1.56). CONCLUSIONS: Among patients with severe secondary mitral regurgitation, the rate of death or unplanned hospitalization for heart failure at 1 year did not differ significantly between patients who underwent percutaneous mitral-valve repair in addition to receiving medical therapy and those who received medical therapy alone.

AIMS: The aim of this study was to identify determinants of in-hospital and mid-term outcomes after isolated tricuspid valve surgery (ITVS) and more specifically the impact of tricuspid regurgitation (TR) mechanism and clinical presentation. METHODS AND RESULTS: Among 5661 consecutive adult patients who underwent a tricuspid valve (TV) surgery at 12 French tertiary centres in 2007-2017 collected from a mandatory administrative database, we identified 466 patients (8% of all tricuspid surgeries) who underwent an ITVS. Most patients presented with advanced disease [47% in New York Heart Association (NYHA) III/IV, 57% with right-sided heart failure (HF) signs]. Tricuspid regurgitation was functional in 49% (22% with prior left-sided heart valve surgery and 27% isolated) and organic in 51% (infective endocarditis in 31% and other causes in 20%). In-hospital mortality and major complications rates were 10% and 31%, respectively. Rates of survival and survival free of HF readmission were 75% and 62% at 5 years. Patients with functional TR incurred a worse in-hospital mortality than those with organic TR (14% vs. 6%, P = 0.004), but presentation was more severe. Independent determinants of outcomes were NYHA Class III/IV [odd ratios (OR) = 2.7 (1.2-6.1), P = 0.01], moderate/severe right ventricular dysfunction [OR = 2.6 (1.2-5.8), P = 0.02], lower prothrombin time [OR = 0.98 (0.96-0.99), P = 0.008], and with borderline statistical significance, right-sided HF signs [OR = 2.4 (0.9-6.5), P = 0.06] while TR mechanism was not [OR = 0.7 (0.3-1.8), P = 0.88]. CONCLUSION: Isolated TV surgery was associated with high mortality and morbidity, both in hospital and during follow-up, predicted by the severity of the presentation but not by TR mechanism. Our results suggest that TV intervention should be performed earlier in the course of the disease.

In this report, we present a new case of mosaic trisomy 13 with prolonged survival, firstly detected by array-CGH analysis which was carried out because of moderate intellectual disability with postaxial hexadactyly, dermatologic features, ventricular septal defect, bicuspid aortic valve, and aortic dystrophy in a 19-year-old male patient. In a subset of 15% of the cells, the patient carried a derivative chromosome 10 generated by a nonreciprocal (10;13) translocation inherited from his healthy mother who carried the translocation in a balanced and homogeneous state. FISH analyses showed interstitial telomeric sequences at the breakpoints. To our knowledge, this is the second report of a patient with trisomy 13 mosaicism displaying a severe aortic root dilatation. We also discuss the mechanisms which could explain the mosaic state, the most likely one being related to the instability of the interstitial telomere.

OBJECTIVES: To analyze the results of extracorporeal life support (ECLS) for cardiogenic shock complicating acute myocardial infarction (AMI) in a single-center experience. BACKGROUND: Cardiogenic shock is still a leading cause of death for AMI. Conventional management carries mortality rates exceeding 50%. ECLS may be considered as a bridge to decision in the setting of AMI complicated by cardiogenic shock not responsive to standard management. METHODS: We performed an observational analysis of our local database. The primary end-point was survival to hospital discharge. All variables were compared between survivors and nonsurvivors. RESULTS: Between January 2007 and December 2017, 56 patients were supported for cardiogenic shock complicating AMI. The mean age was 56.7 years and 89.3% were males. Baseline characteristics were comparable between both groups. Of the 50 primary percutaneous coronary interventions that were attempted, 44 (88.0%) were successful. Twenty-three (41.1%) patients died during ECLS support. The complications' rate during ECLS support was comparable between both groups. Twenty-eight (50%) patients were successfully weaned from ECLS after a mean support of 8.7 days. Eight (14.3%) patients eventually died after weaning before hospital discharge. Five (8.9%) patients could not be weaned from ECLS and were switched to a long-term mechanical circulatory support. Overall survival to hospital discharge was 41.1% (n = 23). Eighteen (32.1%) patients were alive after a mean follow-up of 38.0 ± 29.9 (range, 4.2-95.4) months. CONCLUSIONS: ECLS should be considered as a therapeutic solution in the management of AMI-related cardiogenic shock with a satisfactory short- and long-term survival.

High-risk pulmonary embolism (PE) requires hemodynamic and respiratory support along with reperfusion strategies. Recently updated European guidelines assign a low class of recommendation to extracorporeal membrane oxygenation (ECMO) for high-risk PE. This systematic review assessed clinical outcomes after ECMO in high-risk PE. We searched electronic databases including PubMed, Embase and Web of Science from January 2000 to April 2020. Efficacy outcomes included in-hospital survival with good neurological outcome and survival at follow-up. Safety outcomes included lower limb ischemia and hemorrhagic and ischemic stroke. Where possible (absence of high heterogeneity), meta-analyses of outcomes were undertaken using a random-effects model. We included 16 uncontrolled case-series (533 participants). In-hospital survival with good neurological outcome ranged between 50% and 95% while overall survival at follow-up ranged from 35% to 95%, both with a major degree of heterogeneity (I2 > 70%). The prevalence of lower limb ischemia was 8% (95% CI 3% to 15%). The prevalence of stroke (either hemorrhagic or ischemic) was 11% (95% CI 3% to 23%), with notable heterogeneity (I² = 63.35%). Based on currently available literature, it is not possible to draw definite conclusions on the usefulness of ECMO for high-risk PE. Prospective, multicenter, large-scale studies or nationwide registries are needed to best define the role of ECMO for high-risk PE. PROSPERO registration ID: CRD42019136282.

BACKGROUND: Implantable cardioverter-defibrillator (ICD) lead dysfunction has been reported after left ventricular assist device (LVAD) implantation in limited single-center studies. We aimed at describing and characterizing the incidence of ICD lead parameters dysfunction after LVAD implantation. METHODS: Among the 652 patients enrolled in the ASSIST-ICD study, only patients with an ICD prior to LVAD were included (n = 401). ICD lead parameters dysfunction following LVAD implantation is defined as follows: (a) >50% decrease in sensing threshold, (b) pacing lead impedance increase/decrease by >100Ω, and (c) >50% increase in pacing threshold. RESULTS: One hundred twenty-two patients with an ICD prior to LVAD had available ICD interrogation reports prior and after LVAD. A total of 67 (55%) patients exhibited at least one significant lead dysfunction: 17 (15%) exhibited >50% decrease in right ventricular (RV) sensing, 51 (42%) had >100 Ω increase/decrease in RV pacing impedance, and 24 (20%) experienced >50% increase in RV pacing threshold. A total of 52 patients experienced ventricular arrhythmia during follow-up and all were successfully detected and treated by the device. All lead dysfunction could be managed conservatively. CONCLUSION: More than 50% of LVAD-recipients may experience >1 significant change in lead parameters but none had severe clinical consequences.

BACKGROUND: In patients with secondary mitral regurgitation (MR) associated with low ejection fraction or previous heart surgery, minimally invasive mitral valve surgery without aortic cross-clamp (MIMVS-WAC) has shown promising results. We report our experience for this strategy in our centers. METHODS: Between August 2011 and April 2017, 46 patients (mean age 69 ± 11 years, 76% males) received MIMVS-WAC. Indications for this technique were prior coronary bypass surgery (26%), severe or recent left ventricular (LV) dysfunction (30%), or both (39%). The mean EuroSCORE II was 12 ± 10. RESULTS: For each procedure, we conducted right minithoracotomy and hypothermic cardiopulmonary bypass (CPB) after peripheral cannulation. Mean CPB time was 159 ± 39 minutes. A mitral valve replacement (MVR) was performed in 23 cases (50%), an annuloplasty in 22 cases (48%), and a prosthesis pannus removal in 1 case (2%). Mean hospital length of stay was 12 ± 5.4 days. We report no sternotomy conversions, six reoperations for bleeding, and three deaths at 30 days. Transfusion was requested in 62% (mean infusion 2 ± 2.4 packed red blood cells). The postoperative echocardiography showed an LV function preservation in 69% of cases and a reduction of pulmonary arterial pressure in 73% of cases. Four additional deaths occurred in the long-term follow-up (mean 637 ± 381 days, median 593 days). No mitral reoperation was required, with a MR ≤ 2 in 90% of patients. CONCLUSION: In high-risk patients, the MIMVS-WAC is a safe technique. It avoids hard dissections while ensuring excellent preservation of cardiac function.

BACKGROUND: Functional tricuspid regurgitation (FTR) secondary to left-sided heart disease may lead to poor quality of life and reduced long-term survival. This study evaluated clinical and functional outcomes of patients undergoing tricuspid valve (TV) repair using a rigid three-dimensional ring (Contour 3D, Medtronic) concomitant with another procedure. METHODS: From September 2011 to July 2015, 112 patients (mean age 70.9 ± 9.0 years) were enrolled at 10 centers in Europe, Israel, and the United States. Inclusion criteria were FTR ≥ moderate and/or tricuspid annular diameter (TAD) ≥ 40 mm. Echocardiography was planned before surgery and at discharge with echocardiographic and clinical follow-ups performed 6 months postoperatively. RESULTS: Three fourths (74.4%) of patients had higher than moderate TR. Mean TAD was 41.0 ± 7.3 mm; 61.7% of patients were in the New York Heart Association (NYHA) class III/IV. The most common concomitant procedure was mitral valve repair (57 patients, 53.3%). The 30-day mortality rate was 0.9% (n = 1). The mean EuroSCORE II was 8.9 ± 8.4% (median: 5.9%; interquartile range: 3.5-11.5%). The observed to expected ratio (O/E) based on the median was 0.1. Six deaths occurred during follow-up (three cardiac related). Mean implanted ring size was 30.3 ± 2.7. At 6 months, 94.4% of patients showed ≤ mild TR, and 92.0% were in NYHA class I/II (p < 0.001 vs baseline for both). Mean pressure gradient across the TV was 2.0 ± 1.1 mm Hg; leaflet coaptation length was 7.5 ± 3.3 mm. CONCLUSION: The Contour 3D annuloplasty ring used for treatment of FTR substantially reduced TR for up to 6 postoperative months with low mean pressure gradients across the TV and significant improvement in NYHA class.

A therapeutic dilemma arises when infective endocarditis (IE) is complicated by a neurologic event. Postponement of surgery up to 4 weeks is recommended by the guidelines, however, this negatively impacts outcomes in many patients with an urgent indication for surgery due to uncontrolled infection, disease progression, or haemodynamic deterioration. The current literature is ambiguous regarding the safety of cardiopulmonary bypass in patients with recent neurologic injury. Nevertheless, most publications demonstrate a lower risk for secondary haemorrhagic conversion of uncomplicated ischaemic lesions than the risk for recurrent embolism under antibiotic treatment. Here, we discuss the current literature regarding neurologic stroke complicating IE with an indication for surgery.
