Abstract
OBJECTIVE Percutaneous mitral valve repair with the MitraClip system is an alternative procedure for high-risk patients not suitable for conventional surgery. The MitraClip can be safely performed under general anesthesia (GA) or deep sedation (DS) with spontaneous breathing using a combination of propofol and remifentanil. This study aimed to evaluate the benefits of target-controlled infusion (TCI) of remifentanil and administration of propofol during DS compared with manual administration of total intravenous anesthesia (TIVA) medication during GA in patients undergoing MitraClip. We assessed the impact of these procedures in terms of remifentanil dose, hemodynamic profile, adverse events, and days of hospital stay after the process. PATIENTS AND METHODS From March 2013 to June 2015 (mean age 73.5 ± 9,54), patients underwent transcatheter MitraClip repair, 27 received DS via TCI and 27 GA with TIVA. RESULTS Acute procedural success was 100%. DS-TCI group, in addition to a significant reduction of remifentanil dose administrated (249 µg vs. 2865, p < 0.01), resulted in a decrease in vasopressor drugs requirement for hemodynamic adjustments (29.6% vs. 63%, p = 0.03) during the procedure and a reduction of hypotension (p = 0.08). The duration of postoperative hospitalization did not differ between the two groups (5.4 days vs. 5.8 days, p = 0.4). CONCLUSIONS Administration of remifentanil by TCI for DS in spontaneously breathing patients offers stable anesthesia conditions, with a lower amount of drugs, higher hemodynamic stability, and decreased side effects.

Abstract
Aims
Stratifying prognosis following coronary bifurcation percutaneous coronary intervention (PCI) is an unmet need. Machine learning (ML) may identify patterns from multidimensional, non–linear relationships to make outcome predictions. We sought to develop a ML–based risk stratification model built on clinical, anatomical and procedural features to predict all–cause mortality following contemporary bifurcation PCI.
Methods and Results
Multiple ML models to predict all–cause mortality were tested on a cohort of 2,393 patients (training, n = 1,795; internal validation, n = 598) undergoing bifurcation PCI with contemporary stents from the real–world RAIN (veRy thin stents for patients with left mAIn or bifurcatioN in real life) registry. Among 38 commonly available features, 25 (13 patient–related, 12 lesion–related) were selected to train ML models. The best performing model (the RAIN–ML prediction model) was validated in an external validation cohort of 1,701 patients undergoing bifurcation PCI from the DUTCH PEERS (DUrable polymer–based sTent CHallenge of Promus ElemEnt versus ReSolute integrity: TWENTE II) trial and the BIO–RESORT trial cohorts. The area under the receiver operating characteristic curves for the prediction of 2–year mortality was 0.786 (0.74–0.83) in the overall population, 0.736 (0.72–0.847) at internal validation and 0.706 (0.6919–0.794) at external validation. Performance at risk ranking analysis, k–center cross validation, and with continual learning confirmed the generalizability of the models, available also as an online interface.
Conclusions
The RAIN–ML prediction model represents the first tool combining clinical, anatomical and procedural features to predict all–cause mortality among patients undergoing contemporary bifurcation PCI with a good discriminative performance.

Abstract
OBJECTIVE Spontaneous coronary artery dissection (SCAD) is a spontaneous separation of the coronary artery wall whose etiology appears to be poorly understood. SCAD is a rare cause of acute coronary syndromes, and it is a life-threatening condition. CASE REPORT We report the case of a young woman who developed SCAD during a thyroid storm (TS). RESULTS To the best of our knowledge, this is the first reported case of SCAD during a TS, and it suggests a possible association between high levels of circulating thyroid hormones and SCAD susceptibility. CONCLUSIONS Early identification of SCAD predisposing factors is important to identify high-risk patients. In patients presenting to the emergency department because of chest pain with a history of dysthyroidism, early determination of thyroid hormones and troponin could prevent certain forms of sudden cardiac death.

Abstract
PURPOSE Spontaneous coronary artery dissection (SCAD) may occur in middle age population without any cardiovascular risk factor. We retrospectively evaluated anatomic features of 11 patients with SCAD using a coronary arteries computed tomography (CCT), compared to age and sex balanced patients who underwent CCT. MATERIAL AND METHODS CCT was performed in 11 patients (7 females and 4 males) as follow-up in patients with SCAD (left anterior descending - LAD or circumflex artery - Cx) and compared, using the propensity score matching analysis, with 11 healthy patients. Several anatomic features were evaluated: Left main (LM) length, angle between descending coronary artery (LAD) and its first branch, angle between LAD and LM, distance from the annulus to RCA (a-RCA distance) and LM (a-LM distance) ostia and their ratio; ratio between LM length and length a-LM and tortuosity score of the vessel with SCAD. A fluid dynamic analysis has been performed to evaluate the effects on shear stress of vessels wall. RESULTS LM length was significantly shorter in patients with SCAD versus healthy subjects (P=0.01) as well as LM length/a-LM (P=0.03) and the angle between LAD and the first adjacent branch was sharper (P<0.01). Tortuosity score showed a statistically significant difference between groups (P<0.001). Fluid dynamic analysis demonstrates that, in SCAD group, an angle<90 degree is present at the first bifurcation and it can be a cause of increased strain on vessel wall in patients with high tortuosity of coronary artery. CONCLUSION Tortuosity and angle between the LAD and the adjacent arterial branch combined may determine increased shear stress on the vessel wall that increases the risk of SCAD.

Abstract
Abstract
Background
Ischemic time duration is one of the most important determinants of infarct size in patients with ST-segment elevation myocardial infarction (STEMI). An early reperfusion with percutaneous coronary intervention (PCI) therapy reduces the adverse events and mortality. It also influences the wall motion abnormalities and left ventricular ejection fraction (LVEF), which can be easily detected by a standard transthoracic echocardiogram (TTE).
Purpose
Aim of our study was to assess the immediate effects of an early percutaneous revascularization in STEMI patients on variations of the left ventricle (LV) global and regional function.
Methods
The study population consists of 141 consecutive patients with STEMI undergoing PCI from January to June 2018. The population was divided into two groups basing on first medical contact-to-balloon time (C2B), respectively ≤90 minutes and >90 minutes. Cardiac biomarkers were obtained uniformly. A standard TTE was performed in all patients, at moment of in-hospital admission and at the time of discharge, recording the LV wall motion abnormalities and LVEF, using the wall motion score index (WMSI) and modified Simpson’s rule, respectively. Finally, we performed a sub-analysis in the group of patients who showed an improvement of the LVEF ≥10% at discharge.
Results
In both groups at baseline, patients suffered from a moderately reduced LVEF (41 ± 8.3% in ≤90 min group vs 40.97 ± 8.91% in >90 min group, p = ns). A WMSI >1 was recorded uniformly: 1.78 ± 0.39 in patients with C2B ≤90 min and 1.81 ± 0.40 in patients with C2B >90 min, without significant differences between the two groups. At the time of discharge, a significant improvement of LVEF (from 41 ± 8% to 44 ± 9%, p = 0.013) and WMSI (from 1.78 ± 0.39 to 1.64 ± 0.38, p = 0.036) exclusively emerged in the ≤90 min group. Furthermore, we identified 37 patients who experienced, at the time of discharge, an improvement of the LVEF ≥10% compared to baseline values. In these patients the C2B time resulted significantly shorter, when compared with patients with LVEF improvement <10%: 42 min (IQR 18.5-77.5) vs. 104 (IQR 48-176), p < 0.0001. Additionally, these patients had lower significant levels of cardiac biomarkers. A significant improvement in WMSI was also observed in the ≥10% group (1,69 ± 0,41 vs 1,49 ± 0,41, p= 0.039).
Conclusion
Our study shows the immediate effects of an early revascularization. In particular, the duration of C2B time influences the recovery of ventricular function, in terms of ejection fraction and parietal kinetics. A standard TTE is a low cost and easily available examination, which may provide immediate results without impacting significantly on health costs.

Abstract
Abstract
Background
MitraClip system has developed as a valid therapeutic option in patients affected by moderate to severe and severe mitral regurgitation, low left ventricular ejection fraction (LVEF) and high surgical risk. Often, after the procedure occurs afterload mismatch, an acute and transient worsening of LVEF. Inotropic drugs can improve hemodynamic values at the prize of severe side effects. Levosimendan increases myocardial contractility without an elevation of intracellular calcium concentration, tachyarrhythmia and cardiomyocytes necrosis.
Purpose
Aim of our study was to assess the acute Levosimendan effects on LVEF of patients who underwent MitraClip procedure
Methods
Among 160 patients who underwent MitraClip procedure in our institute, 99 patients, with LVEF ≤35%, were included in the study. Transthoracic echocardiogram was performed in all patients, at moment of hospital admission and at discharge; transesophageal echocardiogram was performed during the procedure. We recorded the LVEF by modified Simpson’s rule. Periprocedural hemodynamic parameters were also recorded. 59 patients received Levosimendan during and early after the procedure (L-group) and 40 patients did not (no-L-group). Levosimendan perfusion was started at 0.01 μg/kg/min 1 h before the procedure without a loading dose, and maintained for 12h, according to hemodynamics.
Results
In the overall population, patients suffered from a severe reduction of LVEF (29.5 ± 5.3%) and high systolic pulmonary arterial pressure (sPAP) (51 ± 14.2 mmHg), without significant difference between the two groups. Acute procedural success was achieved in 98% of the study population, with 2 procedural failures in no-L-group (p = 0.16). During the procedure we observed a significant improvement of LVEF compared to baseline values only in L-group (from 29.6 ± 5.7% to 32.1 ± 7.6%, p = 0.046); in no-L-group the LVEF improved from 29.4 ± 5% to 30.2 ± 4.9% (p = 0.47); at discharge the LVEF was 31.3 ± 4.9% and 30.8 ± 5.7%, in L-group and no-L-group, respectively (p = ns compared to baseline and procedure). At discharge the sPAP significantly reduced in the overall population to 46.3 ± 12.7 mmHg (p 0.015): from 50.8 ± 12.3 mmHg vs 48.7 ± 11.9 in L-group (p = 0.35); from 51.2 ± 16 to 44.3 ± 13.2 mmHg (p = 0.04) in no-L-group. In-hospital mortality was 1.7% in L-group (1 patient die) and 0% in no-L-group. No relevant arrhythmias were reported in any patient during the hospital recovery.
Conclusion
In MitraClip patients with severe reduction of LVEF, Levosimendan has proven to improve hemodynamic outcome, increasing myocardial contractility during and early after procedure.

Abstract
Abstract
BACKGROUND
Early structural valve deterioration (SVD) frequently occurs in Mitroflow aortic bioprosthesis, especially for small sizes (19-mm and 21-mm), and it is associated with reduced overall survival. Treatment by percutaneous valve-in-valve (ViV) implantation is considered a challenging procedure. This is mainly due to an elevated risk of coronary ostia obstruction and high residual post-procedural mean gradients (mG), particularly when severe pre-existing patient-prosthesis mismatch (PPM) is present.
PURPOSE
Aim of our study was to assess the feasibility of transfemoral ViV in small Mitroflow aortic valves using supra-annular self-expanding valves, named CoreValve and Evolut R and Acurate neo and report the midterm clinical results by comparing serum natriuretic peptide type B levels (BNP) before the procedure and at a mean follow-up of 2 years.
METHODS
This is an observational study including 11 patients with stenotic-type SVD of small Mitroflow aortic valves, considered at high/prohibitive risk for surgical reoperation, who underwent ViV implantation between July 2012 and March 2018. We performed echocardiographic assessment of valve hemodynamics (according to VARC-2 definitions) before and after the procedure and during the follow-up. We used the BNP ratio (the ratio between measured serum BNP/NT-proBNP level and maximal normal level) to compare BNP results before the procedure and at follow-up. All-cause mortality during the hospitalization and follow-up was also reported.
RESULTS
The Mitroflow size was 19-mm in 4 patients and 21-mm in 7 patients. Pre-existing severe PPM was present in 4 patients and moderate PPM in 7. CoreValve 26 was implanted in 2 patients, EvolutR 23 in 5 and Acurate neo S in 4 patients. We reported no coronary obstruction, deaths or other major events during the hospitalization. At a mean follow-up of 2 years one patient died. The baseline aortic mG of 56 ± 19 mmHg has significantly reduced after the procedure to 16,6 ± 8 mmHg (p < 0.0001) and follow-up 29,6 ± 16 mmHg (p = 0.008). A post-procedural mG≥20, but <40 mmHg, was observed in 3 patients. BNP ratio at baseline was 14,6 ± 12; only one patient had a BNP ratio <3. At follow-up (n = 7 patients), BNP ratio was significantly lowered to 1,5 ± 1,08 (p = 0.01) with only one patient with a BNP ratio >3. Patients with mPG ≥20 mmHg did not show differences in terms of mortality and reduction of serum BNP levels.
CONCLUSIONS
In our experience the ViV procedure on small degenerated aortic Mitroflow bioprosthesis appears to be technically feasible and provides good midterm clinical results with a net reduction in serum BNP levels, although an increase in mG was observed. Even though a post-procedural mG ≥20 mmHg is considered indicative of suboptimal aortic valve hemodynamics (according to VARC-2 criteria), its correlation with worse outcomes remains unclear and deserves further investigations.

Abstract
Abstract
Background
Chronic kidney disease (CKD) has been shown to impact negatively the prognosis of patients with heart failure, coronary artery or valvular heart disease and emerged as predictor of poor outcomes in mitraclip population.
Purpose
Aim of our study was to evaluate three-year echocardiographic outcomes in CKD patients with severe mitral regurgitation (MR) treated with mitraclip.
Methods
This in an observational study including patients treated with mitraclip in our institution, who completed three years of follow up. Patients population was divided into two groups according to basal creatinine clearance (CrCl): group A, including patients with normal/mild decline of renal function (CrCl > 60 ml/min) and group B, including patients with CKD (CrCl < 60 ml/min). Demographic and procedural characteristics were compared, as well as echocardiographic data, including grade of MR, left ventricular ejection fraction (LVEF), mean transmitral gradient and systolic pulmonary artery pressure (sPAP). Kaplan-Meier survival curves were obtained.
Results
The study population consists of 107 patients (mean age 71 ± 9 years, 69% male): 57 belonging to group A and 50 to group B. Patients of group B had higher values of LogEuroScore (22 ± 10 vs.15 ± 9 p = 0,0002), systemic hypertension (92% vs. 74%, p = 0,026), complicated diabetes (46% vs. 24% p = 0,034) and NYHA IV before the procedure (24% vs 9 %, p = 0,059). Additionally, patients of group B had lower baseline LVEF (35 ± 11 vs. 41 ± 13; p = 0,012). Procedural success was similar between the two groups without significant difference in degree of MR reduction after mitraclip implantation. Echocardiographic follow-up showed that in group B, the LVEF did not improve after the treatment (more than 50% had LVEF < 35% at 1,2 and 3 years) while in the group A it improved significantly (LVEF < 35% from 47,6% at discharge to 29%, 32% and 31% at 1, 2 and 3 years, respectively). In comparison to group A, in group B a progressive increase in residual MR grade was observed (moderate-to-severe MR from 2% at discharge to 14%, 15%, and 27% at 1, 2 and 3 years, respectively) as well as in the mean transmitral gradient (from 3,90 ±1,6 mmHg after the mitraclip implantation to 5,28 ± 1,7; 5,73 ± 1,75; 6,06 ±1,75 at 1, 2 and 3 years, respectively) and sPAP (from 47 ± 12 mmHg at discharge to 49 ± 21; 51 ± 20; 48 ± 22 at 1, 2 and 3 years, respectively). Kaplan Meier estimate of survival free from in-hospital readmission was 77% in group A and 61% in group B (Log-Rank 4.563, p = 0,033) and survival free from cardiovascular death was 95% and 81,5%, in group A and B, respectively (Log-Rank 4.806, p = 0,028).
Conclusion
Our results suggest that CKD patients have poorer outcomes after mitraclip implantation with worsening of some echocardiographic parameters, particularly for residual MR degree, mean transmitral gradient and sPAP, without improvement in LVEF at one, two and three years of follow-up.

Abstract
Abstract
INTRODUCTION
Lactobacillus species are rare human pathogens but have been implicated in a variety of infections, including bacteremia and endocarditis, with Lactobacillus casei and Lactobacillus rhamnosus among the most frequently isolated species. Endocarditis due to Lactobacillus represents <0.5% of all cases of endocarditis and are associated with structural heart diseases, recent surgery, extended antibiotic and probiotic use and immuno-deficiency. We report a case of Lactobacillus plantarumendocarditis in a patient with biological aortic prosthetic valve.
CASE REPORT
Our patient is a 48 year-old male with a past medical history of surgical aortic replacement with a biological prosthetic valve in 2013. He reports the onset of symptoms 4 months before with worsening asthenia. The patient presented to a cardiologist after 3 months from symptoms beginning. A transesophageal echocardiogram (TEE) described marked fibro-plastic thickening of the cusps with two elongated vegetations (12 mm and 7 mm) causing a moderate-to-severe aortic steno-regurgitation. A few days later he came to our emergency department. On admission, the patient was afebrile, eupnoeic on room air. The cardiac examination revealed a regular rate and rhythm with a grade 4 of 6 holosystolic murmur loudest at the aortic and pulmonary focus. Three sets of blood cultures were drawn on admission. Hence, he was transferred to the Infectious Diseases Department where he started antibiotic therapy with Ceftriaxone and Gentamicin. A 18F-FDG PET-CT total body showed tracer accumulation close to the prosthetic aortic valve. Few days later Lactobacillus Plantarum was isolated from blood cultures and, according to the antibiogram results, therapy was adjusted using G Penicillin, Vancomicyn and Gentamicin. The TEE, performed during the hospitalization, showed one mobile vegetation, reduced in size (5 mm), adherent to the anterior aortic cusp, which prolapsed in the left ventricular outflow tract and commissural fusion, causing severe steno-regurgitation (Gmax 84 mmHg, Gmed 54 mmHg). During hospitalization the serial blood cultures resulted negative. Serial TEEs were also performed (3rdand 6thweek), showing a gradual reduction of the cusps thickening and disappearance of commissural fusion (Figure). In the last TEE no vegetations were described, and the transaortic mean gradient was reduced (Gmed 38 mmHg), persisting severe regurgitation. Hence the patient was discharged with oral antibiotic therapy (amoxicillin and clavulanic acid) and indication to redo aortic valve surgery. Written informed consent was obtained.
CONCLUSIONS
L. plantarum is a rare form of endocarditis. In our patient it caused fibro-plastic thickening of the bioprosthesis cusps and commissural fusion, determining severe steno-regurgitation. It also responded to targeted antibiotic therapy with improvement in cusp mobility but persistence of severe regurgitation.

Abstract
Abstract
Introduction
Incidence and predictors of adverse events after dual antiplatelet therapy (DAPT) cessation in patients treated with ultrathin stents in unprotected left main (ULM) or coronary bifurcation remain undefined.
Methods
All consecutive patients presenting with a critical lesion of an ULM or a lesion involving a main coronary bifurcation and treated with very thin strut stents were included. MACE (a composite end point of cardiovascular death, myocardial infarction (MI), target lesion revascularization (TLR) and stent thrombosis (ST) was the primary endpoint, while target vessel revascularization (TVR) was the secondary endpoint. Moreover, type and occurrence of ST and occurrence of ST, CV death and MI during DAPT or after DAPT discontinuation were also evaluated. All analyses were performed according to length of DAPT dividing the patients in 3 groups: short DAPT (3-months), intermediate DAPT (3–12 months) and long DAPT (12-months).
Results
117 patients were discharged with an indication for DAPT≤3 months (median 1:1–2.5), 200 for DAPT between 3 and 12 months (median 8:7–10) and 1958 with 12 months DAPT. After 12.8 months (8–20), MACE was significantly higher in the 3-month group compared to 3–12 and 12-month groups (9.4% vs. 4.0% vs. 7.2%, p≤0.001), mainly driven by MI (4.4% vs. 1.5% vs. 3%, p≤0.001) and overall ST (4.3% vs. 1.5% vs. 1.8%, p≤0.001). ST post DAPT cessation were comparable (1.7% vs. 0% vs. 0.7%, p=0.42) with a median time to ST post DAPT discontinuation of 1.67 months (0.48–4.7). At multivariate analysis, DAPT of 12-months compared to 3-months reduces the risk of overall ST (OR 0.103: 0.019–0.0563, 95% CI) while only a trend was noted for DAPT between 3 and 12 months (OR 0.61: 0.186–2.005, 95% CI). When analysed by stent strategy a 2-stent strategy predicted ST post DAPT cessation (OR 3.241: 1.048–10.026, 95% CI), which was reduced by use of FKB (OR 0.101:0.01–0.872, 95% CI).
Conclusion
Even stents with very thin strut when implanted in real-life ULM or coronary bifurcation patients discharged with short DAPT have a relevant risk of ST, which remains high although not significant after DAPT cessation. The correct identification before PCI of the more fragile patients who may receive a shorter DAPT regimen could help identify the safest PCI technique: provisional stenting and use of final kissing balloon (FKB) are the safest options.

Meta-analysis of the impact on early and late mortality of TAVI compared to surgical aortic valve replacement in high and low-intermediate surgical risk patients. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2019; 23:5402-5412.

Abstract
OBJECTIVE We studied the impact of transcatheter aortic valve implantation (TAVI) compared to the surgical aortic valve replacement (SAVR) on 30-day and one-year mortality from randomized controlled trials (RCTs) in patients with severe aortic stenosis at high or low-intermediate surgical risk. MATERIALS AND METHODS All RCTs were retrieved through PubMed computerized database and the site https://www.clinicaltrials.gov from January 2010 until March 31st, 2019. The absolute risk reduction (RD) with the 95% confidence interval (CI) was used to assess the effectiveness of the intervention under comparison. We evaluated overall mortality rates at 30-day and one-year follow-up in the comparison between TAVI vs. SAVR. We also evaluated the role played by the site access for TAVI performed through the femoral or subclavian artery (TV-TAVI) vs. SAVR, or transapically (TA-TAVI) vs. SAVR. RESULTS In the "as-treated population" the overall 30-day mortality was significantly lower in TAVI (p=0.03) with respect to SAVR. However, the analysis for TAVI subgroups showed that 30-day mortality was (1) significantly lower in TV-TAVI vs. SAVR (p=0.006), (2) increased, not significantly, in TA-TAVI vs. SAVR (p=0.62). No significant differences were found between TAVI vs. SAVR at one-year follow-up. CONCLUSIONS The results of our meta-analysis suggest that TV-TAVI is a powerful tool in the treatment of severe aortic stenosis at high or low-intermediate surgical risk, with a significant lower mortality with respect to SAVR. On the contrary, SAVR seems to provide better results than TA-TAVI.
