Currently, there is no preference for surgical (SAVR) vs transcatheter (TAVR) aortic valve replacement in patients with low ejection fraction (EF). The present study retrospectively compared the ...outcomes of SAVR vs TAVR in patients with EF ≤40% (70 SAVR and 117 TAVR patients). Study outcomes were survival and the composite endpoint of stroke, aortic valve reintervention, and heart failure readmission. The patients who had TAVR were older (median: 75 (25-75th percentiles: 69-81) vs 51 (39-66) years old; P < .001) with higher EuroSCORE II (4.95 (2.99-9.85) vs 2 (1.5-3.25); P < .001). Postoperative renal impairment was more common with SAVR (8 (12.5%) vs 4 (3.42%); P = .03), and they had longer hospital stay 9 (7-15) vs 4 (2-8) days; P < .001). There was no difference between groups in stroke, reintervention, and readmission (Sub-distributional Hazard ratio: .95 (.37-2.45); P = .92). Survival at 1 and 5 years was 95% and 91% with SAVR and 89% and 63% with TAVR. Adjusted survival was comparable between groups. EF improved significantly (β: .28 (.23-.33); P < 0.001) with no difference between groups (P = .85). In conclusion, TAVR could be as safe as SAVR in patients with low EF.

Paediatric del Nido cardioplegia (DNC) has been tested in selected populations of low-risk adult patients. This study examined its use in an unselected medium-to-high-risk adult population and ...compared the results with a propensity-matched population that received intermittent warm blood cardioplegia (IWBC).
Data from the last 1,000 consecutive adult patients who underwent a variety of surgical procedures under cardioplegic arrest with the use of IWBC or DNC between 2016 and 2018 were propensity score matched on preoperative clinical and demographic variables. Two (2) main populations were 102 patients who received DNC and another set of matched 102 patients from a total of 1,000 patients who received IWBC, along with a subgroup with an ejection fraction (EF) ≤40% (EFDNC vs EFIWBC). Postoperative outcomes were mortality, peak troponin T, postoperative EF%, and aortic cross-clamp time.
There were no preoperative differences amongst the groups in the main cohort (Euroscore II: DNC 4.1±8, IWBC 4.0±7; EF%: DNC 47±10, IWBC 47±11) and in the subgroup (EF%: EFDNC 32±6%, EFIWBC 32±6%; p=0.45). There were also no differences in three of the outcomes. A significant postoperative improvement was noticed in the EF% in the DNC (32±6% 95% CI 29-34 to 39±12 95% CI 34-44; p=0.001) in the EFDNC group.
This initial experience of del Nido cardioplegia proved to be effective in a variety of challenging pathologies in adult populations.

We aimed to compare the outcomes of ECMO with and without IABP for postcardiotomy cardiogenic shock. The study included 103 patients who needed ECMO for postcardiotomy cardiogenic shock. Patients ...were grouped according to the use of IABP into ECMO without IABP (n = 43) and ECMO with IABP (n = 60). The study endpoints were hospital complications, successful weaning, and survival. Patients with IABP had lower preoperative ejection fraction (p = 0.002). There was no difference in stroke (p = 0.97), limb ischemic (p = 0.32), and duration of ICU stay (p = 0.11) between groups. Successful weaning was non-significantly higher with IABP (36 (60%) vs 19 (44.19%); p = 0.11). Predictors of successful weaning were inversely related to the high pre-ECMO lactate levels (OR: 0.89; p = 0.01), active endocarditis (OR: 0.06; p = 0.02), older age (OR: 0.95; p = 0.02), and aortic valve replacement (OR: 0.26; p = 0.04). There was no difference in survival between groups (p = 0.80). Our study did not support the routine use of IABP during ECMO support.

Background
Reintervention after transcatheter edge to edge repair using MitraClip is still challenging. We aimed to report our experience in reinterventions after MitraClip procedures and describe ...the outcomes.
Methods
From 2012 to 2020, 167 patients had a transcatheter edge to edge repair; 10 of them needed reinterventions. At the time of the first MitraClip, the median EuroSCORE was 4.29 (2.62–7.52), and the ejection fraction was 30 (20–40)%.
Results
Emergency mitral valve replacement (MVR) was performed in two patients, elective MVR in three, cardiac transplantation in two, and repeat clipping in threepatients. The median time from MitraClip to the reintervention was 4.5 (2–13) months. One patient required extracorporeal membrane oxygenation support after elective MVR. Repeat clipping failed to control mitral regurgitation grade in all patients. Clip detachment was reported in five patients (50%). The median follow‐up after the reintervention was 19.5 (9–75) months, and mortality occurred in two patients who had repeat clipping (20%).
Conclusions
MVR after MitraClip is feasible with low morbidity and mortality. Repeat mitral valve clipping had a high failure rate. Mitral repair was not feasible in all patients in our series, and the use of MitraClip to delay surgical interventions may not be feasible if mitral repair is an option.

Background
Tricuspid valve repair (TVr) is the recommended approach for managing tricuspid regurgitation; however, there is a concern about the long-term durability of the repair. Therefore, this ...study aimed to compare the long-term outcomes of TVr versus tricuspid valve replacement (TVR) in a matched cohort of patients.
Methods
This study included 1161 patients who underwent tricuspid valve (TV) surgery from 2009 to 2020. Patients were grouped according to the procedure into two groups: patients who underwent TVr (n = 1020) and patients who underwent TVR (n = 159). The propensity score identified 135 matched pairs.
Results
Renal replacement therapy and bleeding were significantly higher in the TVR group compared to the TVr group both before and after matching. Thirty-day mortality occurred in 38 (3.79%) patients in TVr group versus 3 (1.89%) in the TVR group (P ≤ 0.001) but was not significant after matching. After matching, TV reintervention (hazard ratio (HR): 21.44 (95% CI: 2.17–211.95); P = 0.009) and heart failure rehospitalization (HR: 1.89 (95% CI: 1.13–3.16); P = 0.015) were significantly higher in the TVR group. There was no difference in mortality in the matched cohort (HR: 1.63 (95% CI: 0.72–3.70); P = 0.25).
Conclusions
TVr was associated with lower renal impairment, reintervention, and heart failure rehospitalization than replacement. TVr remains the preferred approach whenever feasible.

Background
The number of MtraClip procedures is increasing, and consequently, the number of patients with residual or recurrent mitral regurgitation (MR). We aimed to characterize patients who had ...residual versus recurrent MR after MitraClip and report the outcomes of different treatment strategies.
Methods
From 2012 to 2020, 167 patients had MitraClip. Out of them, 16 patients (9.5%) had residual mitral regurgitation (MR), and 27 patients (16.2%) had recurrent MR.
Results
The median age in patients with residual MR was 67.5 (59–73) years versus 69 (61–78) years in patients with recurrent MR (p = .87). The etiology of mitral valve disease was functional in 13 patients (81.3%) and 22 patients (84.6%) in residual versus recurrent MR patients (p > .99). Cardiac resynchronization therapy‐defibrillator implantation was higher in patients with residual MR (p = .02). Survival was 93.7% at 1 year, 76.4% at 3 years versus 92.5% at 1 year, and 84.5% at 3 years in residual versus recurrent MR (p = .69). Two patients in the residual MR group had re‐clip, and three had surgery, and in the recurrent MR group, one patient had re‐clip, and two patients had surgery (p = .23). Patients who had re‐clip were older (p = .09). Surgery was associated with 100% survival at 5 years, 63% after medical therapy and the worst survival was reported in re‐clip patients (p = .007).
Conclusion
The outcomes of patients with residual versus recurrent mitral regurgitation after MitraClip were comparable. Survival could be improved with surgery compared with medical therapy and re‐clip.

Obstruction of a mechanical aortic valve by pannus formation at the subvalvular level is a major long-term complication of aortic valve replacement (AVR). In fact, pannus is sometime difficult to ...differentiate from patient-prosthesis mismatch or valve thrombosis. In most cases cine-angiography and echocardiography, either transthoracic or transesophageal, cannot correctly visualize the complication when the leaflets show a normal mobility. Recent technological refinements made this difficult diagnosis possible by ECG-gated computed tomography (CT) scan which shows adequate images in 90% of the cases and can differentiate pannus from fresh and organized thrombus.
Persistent atrial fibrillation frequently shows multiple different electrophysiological mechanisms of induction. This heterogeneity causes a low success rate of single procedures of ablation and a ...high incidence of recurrence. Surgical ablation through bilateral thoracotomy demonstrates better results after a single procedure. Prospective observational studies in inhomogeneous populations without control groups report a remarkable 90% of success with hybrid or staged procedures of surgical ablation coupled with catheter ablation. In this trial, we will examine the hypothesis that a staged approach involving initial minimally invasive surgical ablation of persistent atrial fibrillation, followed by a second percutaneous procedure in case of recurrence, has a higher success rate than repeated percutaneous procedures.
This is a controlled (2:1) randomized trial comparing use of a percutaneous catheter with minimally invasive transthoracic surgical ablation of persistent atrial fibrillation. The inclusion and exclusion criteria, definitions, and treatment protocols are those reported by the 2012 Expert Consensus Statement on catheter and surgical ablation of atrial fibrillation. Patients will be randomized to either percutaneous catheter (n = 100) or surgical (n = 50) ablation as the first procedure. After 3 months, they are re-evaluated, according to the same guidelines, and receive a second procedure if necessary. Crossover will be allowed and data analyzed on an "intention-to-treat" basis. Primary outcomes are the incidence of sinus rhythm at 6 and 12 months and the proportions of patients requiring a second procedure.
The use of a staged strategy combining surgical and percutaneous approaches might be more favorable in treatment of persistent atrial fibrillation than the controversial single percutaneous ablation.
