Abstract OBJECTIVES Intraoperative transesophageal echocardiography (iTEE) has an important role in diagnosing the results of mitral valve (MV) replacement and repair. However, intraoperative Doppler features may be dissimilar from those measured at the postoperative follow-up period due to hemodynamic variations. There are no studies regarding MV surgery and comparisons between iTTE and postoperative transthoracic echocardiography (post-TTE). We aimed to evaluate the Doppler flow profiles observed in iTEE after MV replacement and repair and compare them with those observed in post-TTE.METHODS We conducted an observational study of 76 patients who underwent MV surgery (replacement or repair) over a 10-month period. iTEE was performed with Doppler evaluation (mean pressure gradient [MPG] and functional area). Patients were re-evaluated with TTE 72 hours after surgery (post-TTE). iTEE and post-TTE Doppler values were then compared and correlated.RESULTS The patients’ mean age was 59 ± 18 years and 55% were women. The prevalence of severe mitral regurgitation and severe mitral stenosis was 77.6% and 22.4%, respectively. MV repair was performed in 71% of cases. iTEE Doppler parameters correlated with post-TTE parameters, with minimal differences, specially in the MV repair group. The postoperative MPG was +0.4 ± 1 mmHg higher in the MV repair group and +1.0 ± 1.8 mmHg in the MV replacement group. There was global improvement in terms of systolic pulmonary artery pressure, although left ventricular ejection fractions were slightly reduced during the postoperative evaluation.CONCLUSIONS Our study demonstrates the usefulness of iTEE and its importance in establishing possible reference values for postoperative follow-ups.

Abstract BACKGROUND Intraoperative transesophageal echocardiography (iTEE) has an important role in mitral valve (MV) surgery, but may have dissimilar parameters from postoperative echocardiography (post-TTE). We aimed to evaluate iTTE Doppler flow profile and compare with the post-TTE in MV surgery. METHODS We conducted a prospective, observational study of 126 patients that underwent MVsurgery during 2 years. iTEE evaluated mean pressure gradient (MPG) and functional area. Patients were re-evaluated with TTE, 72 hours after surgery (post-TTE). iTEE and post-TTE Doppler values were compared and correlated. Preoperative TTE (pre-TTE) parameters were also determined. RESULTS The mean age was 59 ± 18 years and 55% were female. The prevalence of severe mitral regurgitation (MR) was 77.6% and severe mitral stenosis (MS) 23.7%. Globally, mitral valve repair was performed in 71%cases (83% for MR and 15% for MS) and replacement in 29% (64% for MR and 46% for MS). Left ventricular ejection fraction (LVEF), systolic pulmonary artery pressure (sPAP), tricuspid annular plane systolic excursion (TAPSE) assessed in pre-TTE and post-TTE, as also MPG and functional area in post-TTE and iTEE are depicted on table 1. There was a higher numerical difference in iTEE vs post-TTE MPG values in mechanical valves (n = 5) (3.5 ± 1.2 to 5.2 ± 1.6, difference of 1.65 ± 2.4mmHg), than in biological valves (n = 17) (3.1 ± 1.1 to 3.9 ± 1.5, difference of 0.8 ± 1.7mmHg). Globally, iTEE-derived MPG and functional area were strongly correlated with their post-TTE values (r2 0.7 and 0.8,p < 0.001). CONCLUSIONS iTEE Doppler parameters were strongly correlated with postoperative TTE parameters, with minimal differences: postoperative MPG were +0.4 ± 1mmHg higher in MV repair and +1.0 ± 1.8mmHg in MV replacement. There was a global improvement in sPAP. Our study demonstrates the usefulness of iTEE and its importance in stablishing possible reference values for postoperative follow-up.

Objective: To identify echocardiographic and surgical risk factors for failure after mitral valve repair. Methods: We identified a total of 77 consecutive patients from our institutional mitral valve surgery database who required redo mitral valve surgery due to recurrence of mitral regurgitation after primary mitral valve repair. A control group of 138 patients who had a stable echocardiographic long-term result was included based on propensity score matching. Systematic analysis of echocardiographic parameters was performed before primary surgery; after mitral valve repair and prior to redo surgery. Risk factor analysis was performed using multivariate Cox regression model. Results: Redo surgery was associated with the presence of pulmonary hypertension ≥ 50 mmHg (p = 0.02), a mean transmitral gradient > 5 mmHg (p = 0.001), left ventricular ejection fraction ≤ 45% (p = 0.05) before surgery and mitral regurgitation ≥moderate at time of discharge (p = 0.002) in the whole cohort. Patients with functional mitral valve regurgitation had a higher tendency to undergo redo surgery if preoperative left ventricular end-diastolic diameter exceeded 65 mm (p = 0.043) and if postoperative tenting height exceeded 6 mm (p = 0.018). Low ejection fraction was not significantly associated with the need for redo mitral valve surgery in the functional subgroup. Conclusions: Recurrent mitral regurgitation is still a valuable problem and is associated with relevant perioperative mortality. Patients with severe mitral regurgitation should undergo early mitral valve repair surgery as long as systolic pulmonary artery pressure is low, left ventricular ejection fraction is preserved, and LVEED is deceeds 65 mm.

Background: Data regarding ventricular tachycardia (VT) or premature ventricular complex (PVC) ablation following MVS is limited.) CA can be challenging given perivalvular substrate in the setting of mitral annuloplasty or prosthetic valves. Objective: To investigate the characteristics, safety, and outcomes of radiofrequency catheter ablation (CA) in patients with prior mitral valve surgery (MVS) and ventricular arrhythmias (VA). Methods: We identified consecutive patients with prior MVS who underwent CA for VT or PVC between January 2013- December 2018. We investigated the mechanism of arrhythmia, ablation approach, peri-operative complications, and outcomes. Results: In our cohort of 31 patients (77% men, mean age 62.3±10.8 years, left ventricular ejection fraction 39.2±13.9%) with prior MVS underwent CA (16 VT; 15 PVC). Access to the left ventricle was via transseptal approach in 17 patients, and a retrograde aortic approach was used in 13 patients. A combined transseptal and retrograde aortic approach was used in one patient, and a percutaneous epicardial approach was combined with trans-septal approach in 1patient. Heterogenous scar regions were present in 94% of VT patients and scar-related reentry was the dominant mechanism of VT. Clinical VA substrates involved the peri-mitral area in 6 patients with VT and 5 patients with PVC ablation. No procedure-related complications were reported. The overall recurrence-free rate at 1-year was 72.2%; 67% in the VT group and 78% in the PVC group. No arrhythmia-related death was documented on long-term follow-up. Conclusion: CA of VAs can be performed safely and effectively in patients with MVS

ObjectiveMinimally invasive surgery is increasingly adopted as an alternative to conventional sternotomy for mitral valve pathology in many centres worldwide. A systematic safety analysis based on a comprehensive list of pre-specified 30-day complications defined by the Mitral Valve Academic Consortium (MVARC) criteria is lacking. The aim of the current study was to systematically analyse the safety of minimally invasive mitral valve surgery in our centre based on the MVARC definitions.MethodsAll consecutive patients undergoing minimally invasive mitral valve surgery through right mini-thoracotomy in our institution within 10 years were studied retrospectively. The primary outcome was a composite of 30-day major complications based on MVARC definitions.Results745 patients underwent minimally invasive mitral valve surgery (507 repair, 238 replacement), with a mean age of 62.9±12.3 years. The repair was successful in 95.8%. Overall 30-day mortality was 1.2% and stroke rate 0.3%. Freedom from any 30-day major complications was 87.2%, and independent predictors were left ventricular ejection fraction <50% (OR 1.78; 95% CI 1.02 to 3.02) and estimated glomerular filtration rate <60 mL/min/1.73 m2 (OR 1.98; 95% CI 1.17 to 3.26).ConclusionsMinimally invasive mitral valve surgery is a safe technique and is associated with low 30-day mortality and stroke rate.

The optimal timing of mitral valve surgery in patients with severe organic mitral regurgitation (OMR) and no or mild symptoms is highly controversial. The aim of this study was thus to determine the preoperative predictors of mortality following mitral valve surgery in patients with severe OMR and no or mild symptoms. Preoperative and operative data of 324 patients (65% of male, mean age: 65±13 years) with severe OMR and no/mild symptoms (NYHA class I and II) who underwent mitral valve surgery between 1992 and 2007 were prospectively collected in a computerized database. Mitral valve repair (MVRp) was performed in 132 (41%) and mitral valve replacement (MVR) in 187 (59%) patients. Operative mortality was low for both procedures (whole cohort: n=9, 2.7%; MVRp: n=2, 1.5%; MVR: n=7, 3.7%; p=0.34) but was significantly higher in the patients (n=167, 56%) with impaired preoperative left ventricular ejection fraction (LVEF) (<60%) (5.3% vs. 1.2%, p=0.04). Long-term survival was 93±2% at 5 years and 87±3% at 10 years. Patients with LVEF<60% had significantly reduced long-term survival compared to patients with normal LVEF (5-year: 89±4% vs. 95±5%, 10-year: 80±6% vs. 88±4%, p=0.049). Multivariate analysis identified age (Hazard-ratio [HR]= 1.03, 95% confidence interval (CI): 1–1.08, p=0.02), heart failure (HR= 1.9, 95%CI: 1.3–3, p= 0.0018), and LVEF (HR= 1.04, 95%CI: 1.01–1.07, p=0.0253) as independent predictors of long-term mortality. Furthermore, MVR was not associated with worse long-term survival on both univariate (p=0.83) and multivariate (p=0.98) analysis. Performing mitral valve surgery is safe in patients with severe OMR and no or mild symptoms. Impaired LVEF is associated with increased short- and long-term mortality, suggesting that these patients should be promptly operated before the onset of LV dysfunction.

The Impact

Abstract Background Limited information has been reported regarding the impact of percutaneous mitral valve repair (PMVR) on ventricular arrhythmic (VA) burden. The aim of this study was to address the incidence of VA and appropriate antitachycardia implantable cardiac defibrillator (ICD) therapies before and after PMVR. Methods We retrospectively analyzed all consecutive patients with heart failure with reduce left ventricular ejection fraction, functional mitral regurgitation grade 3+ or 4+ and an active ICD or cardiac resynchronizer who underwent PMVR in any of the eleven recruiting centers. Only patients with complete available device VA monitoring from one-year before to one year after PMVR were included. Baseline clinical and echocardiographic characteristics were collected before PMVR and at 12-months follow-up. Results 93 patients (68.2±10.9 years old, male 88.2%) were enrolled. PMVR was successfully performed in all patients and device success at discharge was 91.4%. At 12-months follow-up, we observed a significant reduction in mitral regurgitation severity, NT-proBNP and prevalence of severe pulmonary hypertension and severe kidney disease. Patients also referred a significant improvement in NYHA functional class and showed a non-significant trend to reserve left ventricular remodeling. After PMVR a significant decrease in the incidence of non-sustained ventricular tachycardia (VT) (5.0–17.8 vs 2.7–13.5, p=0.002), sustained VT or ventricular fibrillation (0.9–2.5 vs 0.5–2.9, p=0.012) and ICD antitachycardia therapies (2.5–12.0 vs 0.9–5.0, p=0.033) were observed. Conclusion PMVR was related to a reduction in arrhythmic burden and ICD therapies in our cohort. Proportion of patients who presented ven Funding Acknowledgement Type of funding source: None
