Abstract
Abstract
Background
Several factors have been identified as predictors of events after transcatheter aortic valve implantation (TAVI) but the impact of transaortic flow (F) and mean transaortic gradient (MG) upon outcomes is controversial. This study aimed to clarify the prognostic role of low FL and low MG after TAVI.
Methods
Patients with severe and symptomatic aortic stenosis [effective orifice area (EOA) ≤1cm2], referred for TAVR at our institution were consecutively enrolled. Given the aim of this analysis, patients were divided according to F and MG into four groups: 1) LF-LG Patients with low flow (SVi <35ml/m2) and low mean gradient (MG <40mmHg), 2) NF-LG Patients with normal flow (SVi ≥35ml/m2) and low mean gradient (MG <40mmHg), 3) LF-HG Patients with low flow (SVi <35ml/m2) and high mean gradient (MG ≥40mmHg) and 4) NF-HG patients with normal flow (SVi ≥35ml/m2) and high mean gradient (MG ≥40mmHg). Prospectively collected demographic, laboratory and echocardiographic data were retrospectively analyzed. One-year outcomes were compared between the 4 groups of patients. Primary clinical endpoint was all-cause mortality at long term follow up, as defined by the criteria proposed by the Valve Academic Research Consortium2.
Results
In total 255 patients undergoing TAVI at our institution were included in our study: 35 (13.7%) patients with LF-LG, 17 (6.7%) with NF-LG, 108 (42.4%) with LF-HG and 95 (37.3%) with NF-HG. There was a statistically significant difference in gender distribution between the groups with most females being represented in the NF-HG group (64.2%) vs the LF-LG (31.4%), the NF-LG (47.1%) or the LF-HG group (50.9%) (p=0.008). Moreover, LF-LG patients were younger than NF-LG, LF-HG or NF-HG patients (ANOVA, p=0.037). There was a greater prevalence of prior myocardial infarction (MI) in the LF-LG group (34.5%) vs 20% in the NF-LG, 16.1% in the LF-HG and 20.2% in the NF-HG group (p=0.005). At 1 year follow up there were no statistically significant differences in major vascular complication, major bleeding complication or permanent pacemaker implantation rates between the groups, (all p>0.05). At a median follow up of 36 months IQR (17, 56) all-cause mortality was significantly higher in the LF-LG group as opposed to the NF-LG, LF-HG and NF-HG groups (77.41% vs 60% vs 55.67% vs 46.15% respectively, p=0.005). These results were confirmed by multivariate logistic regression analysis, as the combination of low flow and low mean gradient emerged as the strongest long term all cause mortality predictor (HR: 5.39, 95% confidence intervals: 1.72–16.83; p=0.004)
Conclusion
Combination of low flow and low mean transaortic gradient portends a worse prognosis after TAVI.

Abstract
Abstract
Background
Mitral regurgitation (MR) is commonly encountered in patients with severe aortic stenosis scheduled for transcatheter aortic valve implantation (TAVI). The presence of significant pre-procedural MR, however, has not been accounted in pivotal trials of TAVI and data regarding its independent impact on outcome are contradictory.
Methods
Patients with severe and symptomatic aortic stenosis [effective orifice area (EOA) ≤1cm2] referred for TAVI at our institution were consecutively enrolled. Prospectively collected demographic, laboratory and echocardiographic data were retrospectively analysed. Patients were stratified into two groups according to MR severity: ≤ grade 1 were defined as non-significant and ≥ grade 2 as significant. Change in MR was determined by comparison between baseline and 30-day echocardiogram. Primary clinical endpoint was all-cause mortality, as defined by the criteria proposed by the Valve Academic Research Consortium2.
Results
A total of 331 consecutive patients were enrolled in the study: 247 (74.6%) had non-significant MR and 84 (25.4%) patients had significant MR at baseline. Patients with significant pre-procedural MR had lower baseline ejection fraction (47.7±10.4% versus 51.2±8.4%, p=0.002), higher pulmonary artery systolic pressure (52±14.3mmHg versus 42.5±11.1mmHg, p<0.0001) and higher rates of moderate or severe tricuspid regurgitation (TR) (50% versus 19.4%) compared to patients with non-significant MR. Of all patients, mitral regurgitation improved in 9.5%, remained the same in 83.9%, and worsened in 6.6% 30 days after TAVR. In a multivariable analysis, pre-procedural TR severity was predictor of improved mitral regurgitation [OR 3.003,(95% CI 1.216–7.417, p=0.017)].
The primary clinical end point occurred in 44.7% of all patients during a follow-up period of 36.6.±25.9 months. Patients with significant pre-procedural MR had significantly higher rates of all-cause mortality compared to patients with non-significant (54.7% and 41.3%, respectively; log rank p=0.015). Performing a multivariable analysis demonstrated that preprocedural MR severity could independently predict cumulative mortality [OR 0.480, (95% CI 0.247–0.932, p=0.03)].
Conclusion
Significant pre-procedural MR is common in patients undergoing TAVI and is associated with increased all-cause mortality. TAVI is associated with a significant improvement in MR, especially in severe types. These data provide new insights in the crucial role of mitral regurgitation in the risk assessment of TAVI candidates.

Arterial stiffness and valvular calcifications in aortic stenosis: caught between a rock and a hard place. Eur Heart J 2021.

Abstract
Abstract
Background/Introduction
Arterial stiffness and aortic hemodynamics are independent predictors of adverse cardiovascular events. Indications for transcatheter aortic valve implantation (TAVI) are expanding and aortic valve calcifications (AVC) are an important prognostic factor of the success of TAVI.
Purpose
We sought to investigate the associations between AVC and aortic vascular function/hemodynamics.
Methods
Fifty-two high-risk patients (mean age 80.4±8.5 years, 27 male) with severe symptomatic aortic stenosis undergoing TAVI were included. Arterial stiffness was estimated through carotid-femoral pulse wave velocity (cfPWV) and brachial-ankle pulse wave velocity (baPWV). Aortic hemodynamics (aortic pressures, aortic augmentation index corrected for heart rate [AIx@75]) were also measured. Measurements were conducted prior to the implantation and at discharge. In all patients, a native and contrast-enhanced multislice cardiac computed tomography were performed pre-interventionally. AVC were then graded semi-quantitatively as follows: grade 1 – no calcification; grade 2 – mildly calcified (small isolated spots); grade 3 – moderately calcified (multiple larger spots); grade 4 – severely calcified (extensive calcification of all cusps).
Results
Group 1 (subjects with none/mild AVC, n=29) did not significantly differ in age, gender and body-mass index compared to group 2 (subjects with moderate/severe AVC, n=23). As far as the traditional cardiovascular risk factors were concerned, only hypertension (p=0.008), coronary artery disease (p=0.016), atrial fibrillation (p=0.075) and insulin-dependent diabetes mellitus (p=0.068) were found to be more prevalent in group 2. Group 2 had significantly higher both cfPWV and baPWV (8.3±1.7 vs 7.2±1.2 m/s and 1750±484 cm/s vs. 2101±590 cm/s with p=0.008 and p=0.022 respectively) compared to Group 1 (Figure 1). Even after adjustment for age, gender and systolic blood pressure, aortic stiffness indices were higher in Group 2 compared to Group 1 (p=0.038 and p=0.048, respectively). There was no statistically significant difference in peripheral or aortic pressures as well as in wave reflections indices between the two groups.
Conclusion
Our study shows that in patients with aortic valve stenosis there is a correlation between increased aortic stiffness and a greater extent of damage of aortic valvular leaflets as well as calcifications.

Abstract
Abstract
Background
Many patients undergoing transcatheter aortic valve implantation (TAVI) have concomitant mitral regurgitation (MR) of moderate grade or more. The impact of coexistent tricuspid regurgitation (TR) remains to be determined.
Methods
Patients with severe and symptomatic aortic stenosis [effective orifice area (EOA)≤1cm2] referred for TAVI at our institution were consecutively enrolled. Prospectively collected demographic, laboratory and echocardiographic data were retrospectively analysed. Patients were divided into 4 groups according to MR and TR severity pre-procedurally: no/mild MR and TR, moderate/severe MR, moderate/severe TR, moderate/severe MR and TR. Primary clinical endpoint was all-cause mortality, as defined by the criteria proposed by the Valve Academic Research Consortium2.
Results
A total of 244 consecutive patients were enrolled in the study: 148 (60.7%) patients no/mild MR and TR, 32 (13.1%) moderate/severe MR, 35 (14.3%) moderate/severe TR, 29 (11.9%) moderate/severe MR and TR pre-procedurally. There was significant difference in pre-procedural pulmonary artery systolic pressure (PASP) among groups (no/mild MR and TR: 40.8±10 mmHg, moderate/severe MR: 46.6±11.2 mmHg, moderate/severe TR: 49.9±13mmHg, moderate/severe MR and TR: 59.8±15.2mmHg, p<0.0001). The Kaplan–Meier curves for 2 year mortality showed that the severity of TR was associated with poor survival. Interestingly, patients with moderate/severe MR and TR had the worse survival (no/mild MR and TR (91.2%), moderate/severe MR (78.1%), moderate/severe TR (62.9%), moderate/severe MR and TR (62.1%), p<0.0001).
Conclusion
The presence of concomitant moderate or severe mitral and tricuspid valve regurgitation was associated with the higher mortality. This suggests that a thorough evaluation of the mechanisms underlying concomitant mitral and tricuspid valve regurgitation should be performed to determine the best strategy for avoiding TAVI-related futility.

Abstract
Abstract
Introduction
Transcatheter aortic valve implantation is the treatment of choice in a consistently expanding group of patients with severe aortic valve stenosis. Tricuspid and mitral annular dilatation with consequent valvular regurgitation are associated with adverse outcome. Computed tomography angiography (CTA) is routinely performed for preprocedural evaluation of vascular access and prosthesis sizing.
Purpose
To evaluate the impact of mitral and tricuspid annular dimensions in preprocedural CTA on prognosis of patients undergoing TAVI with a self-expanding valve.
Methods
CTAs of consecutive patients undergoing TAVI in a single high-volume center between 2016 and 2019 were retrospectively evaluated. Maximal septolateral tricuspid annular diameters (TAD) and mitral annular diameters (MAD) were obtained and measured from properly angulated three dimensional CTA datasets. Moreover, maximal pulmonary artery diameter perpendicular to the long axis was measured in every patient. Patients were followed up by clinical visits or telephone contacts. As clinical events were defined all-cause mortality, stroke and heart failure hospitalization.
Results
In total 123 patients were included in the study. The mean follow-up duration was 875±383 days and 21 clinical events were recorded. There was a moderate but statistical significant correlation between TAD and both pulmonary artery diameter (r=0.39, p<0.001) and pulmonary artery systolic pressure by echocardiography (r=0.23, p=0.015). In univariate logistic regression analysis pulmonary artery diameter and TAD were both associated with heart failure hospitalization (p=0.03 and 0.02 respectively). In addition, MAD was associated with total events (OR: 0.43, 95% CI 0.19–0.99, p=0.048). The relationship of MAD with events remained significant after adjustment for sex, age and tricuspid annular dimensions (OR: 0.28, 95% CI 0.1–0.79, p=0.02).
Conclusions
TAD and MAD were associated with heart failure rehospitalization and clinical events respectively in patients undergoing TAVI with a self-expanding valve. Further larger prospective studies are warranted to evaluate the prognostic value of these CTA markers.

Abstract
Abstract
Background
Access options for transcatheter aortic valve implantation (TAVI) are vital, since use of large sheaths may lead to access-related complications and bleeding.
Purpose
To determine the access-related vascular and bleeding complications of patients undergoing transfemoral TAVI.
Methods
Consecutive patients scheduled for transfemoral TAVI were retrospectively grouped according to vascular access [percutaneous access (p-TAVI) and surgical cutdown (sc-TAVI)]. Primary end points were vascular and bleeding complications, based on the VARC-II criteria.
Results
Totally, 187 patients were included in the analysis (p-TAVI: 124 patients; sc-TAVI: 63 patients). Mean procedure time was shorter in the p-TAVI group compared to the sc-TAVI group (45.65±6.17 min versus 64.05±15.73 min, p<0.001). Contrast use was lower in the p-TAVI group compared to the sc-TAVI group (81.18±15.96 ml versus 106.75±25.67 ml, p<0.001), which resulted in higher rates of acute kidney injury in the sc-TAVI group (13% versus 1%, p=0.01). Vascular access complications occurred numerically but not statistically more often in the p-TAVI group compared to the sc-TAVI group (11% versus 5% for minor complications and 6% versus 3% for major complications respectively, p=0.10). Patients in the p-TAVI group had the same minor and major bleeding complications compared to the sc-TAVI group (11% versus 8% for minor, 10% versus 6% for major bleeding complications respectively, p=0.49), but no life-threatening bleeding (0% versus 1.5%).
Conclusions
Transfemoral access options in TAVI (surgical cutdown or percutaneous) have similar efficacy and should be offered in TAVI patients if and when appropriate.

Abstract
Abstract
Aims
Paravalvular leak (PVL) remains a frequent complication after transcatheter aortic valve implantation (TAVI) and seems to affect short- and long-term survival.
Purpose
The aim of this study was: 1) to identify anatomical predictors of PVL after TAVI and 2) assess the impact of PVL on cumulative survival.
Methods and results
Patients with severe and symptomatic aortic stenosis [effective orifice area (EOA) ≤1cm2] referred for TAVI at our institution were consecutively enrolled. Prospectively collected demographic, laboratory and echocardiographic data were retrospectively analyzed. Patients were stratified into two groups according to the presence of PVL after TAVI and were followed up postoperatively with clinical and echocardiographic assessment. Primary clinical endpoint was all-cause mortality, as defined by the criteria proposed by the Valve Academic Research Consortium 2. In total, 291 patients were included (male: 50.2%, mean age: 80±7.6 years) in our study. Of these, 165 (56,8%) presented at least mild PVL after TAVI (mild: 85,5%, moderate: 13.3% and severe: 1.2%). The median follow-up period was 27.3 [min. 0, max 113 months. Two patients with severe PVL were excluded from the analysis. In the follow up period, there was no significant difference regarding all-cause mortality between patients with and those without PVL after TAVI, independently from the degree of PVL (log rank: 0.991 - Figure 1). Severe aortic annulus calcification, the presence of a bicuspid aortic valve and aortic root angulation, as assessed by computed tomography (CT), were found to associate with PVL after TAVI in univariate analysis. In the multivariate analysis, severe aortic annulus calcification was found to be the only independent predictor of mild or moderate PVL after TAVI [Exp(B): 1.540, 95% Confidence Interval: 1.067–2.224, B=0.432, p=0.021].
Conclusion
The presence of mild or moderate PVL after TAVI was not found to affect cumulative survival in the 27 months of follow up period. Severe annulus calcification assessed by CT-scan, was found to be the only independent predictor of PVL after TAVI.

Aortic systolic blood pressure predicts periprocedural myocardial injury after transcatheter aortic valve implantation. Eur Heart J 2021.

Abstract
Abstract
Background/Introduction
Periprocedural myocardial injury (PPMI) is a complication of transcatheter aortic valve implantation (TAVI) associated with worse outcome. Central (aortic) systolic blood pressure (SBP) is an independent predictor of cardiovascular events.
Purpose
We sought to investigate the effect of TAVI on peripheral and central hemodynamics, as well as the predictive ability of brachial and aortic SBP for PPMI.
Methods
We enrolled 70 patients (mean age 79.9±8.7 years, 50% males) with severe symptomatic aortic valve stenosis (AVS) undergoing TAVI. Brachial pressures were measured with an oscillometric device and central pressures were assessed by arterial tonometry at baseline and after the procedure at discharge. PPMI was identified based on Valve Academic Research Consortium (VARC-2) criteria. Biomarkers for MI (cardiac troponin and creatinine kinase MB) were analyzed and signs and symptoms according to VARC-2 criteria were collected from clinical records. Stepwise multivariable regression analysis was performed for the prediction of PPMI.
Results
According to VARC-2 definition, 38 (54%) patients had PPMI. In stepwise multivariable regression analysis, brachial SBP at baseline was not predictive of PPMI (p=0.07) after adjusting for age, sex and history of coronary artery disease. On the contrary, aortic SBP predicted PPMI even after adjustment for the abovementioned confounders (Odds ratio [OR]=1.032, 95% Confidence Interval [CI] 1.004–1.061, p=0.026). Interestingly, both SBP and aortic SBP were higher at discharge in patients with PPMI compared to patients without PPMI after adjustment (p=0.021 and p=0.006, respectively). On the contrary, the periprocedural changes of aortic SBP and SBP were not different between patients with PPMI and without PPMI.
Conclusions
Aortic SBP, as assessed by tonometry, is an independent predictor stronger than brachial SBP for PPMI in AVS patients treated with TAVI. This finding suggests the possible clinical role of aortic pressures as a risk stratification tool for PPMI prior to TAVI, as well as, warrants further investigation on their role as therapeutic targets to decrease the incidence of PPMI.

Introduction/Purpose: Patent foramen ovale (PFO) is common in asymptomatic adults and is associated with cryptogenic stroke (CS). We sought to evaluate the impact of PFO closure in health-related quality of life (HRQoL) in PFO patients with CS.
Method
In this pilot study, 19 patients (mean age 47 ± 7.7; 13 male) who underwent PFO closure at our center were invited to a short-term clinical follow up (mean follow-up period 6-10 months). All patients had suffered an ischaemic stroke and their disability level was assessed using the Modified Rankin Scale (MRS, no significant disability 63%). HRQoL was assessed using the 36-Item Short Form Survey (SF-36) and the European Quality of Life-5 Dimensions Questionnaire (EQ-5D) preoperatively and at follow-up.
Results
Both SF36 and EQ-5D scores improved after the operation as shown by the self-rating scores (20,67% and 40,52% higher scores, respectively). Patients with major mobility problems were more likely to be current smokers (r = 0.481) and those who had lower scores on the MRS scale (r=-0.571) rated higher their scale diagram. The categories of energy/fatigue (r = 0.459; p = 0.048), social functioning (r = 0.547; p = 0.015) and pain (r = 0.550; p = 0.015) were positively correlated with physical function. Finally, there was a positive correlation between role limitations due to emotional problems and energy/fatigue (r = 0,519; p = 0.023), and between energy/fatigue and emotional well-being (r = 0.519; p = 0,023).
Conclusions
The results of our study indicate that shortly after PFO, subjects perceive improvements in their QoL. However, it seems that poorly rated physical function was more common in active smokers, and affects patients" social life and their emotional state. Health care professionals should encourage these patients to participate in rehabilitation and psychological support programs postoperatively.

Abstract
Abstract
Purpose
Transcatheter aortic valve implantation (TAVI) is often followed by conduction abnormalities, leading to a permanent pacemaker implantation (PPI). Data regarding the clinical impact of PPI following TAVI is yet to be established.
Methods
Patients with severe and symptomatic aortic stenosis [effective orifice area (EOA) ≤1cm2] referred for TAVI at our institution were consecutively enrolled. Prospectively collected demographic, laboratory and echocardiographic data were retrospectively analyzed. Patients were stratified into two groups according to the need for PPI after TAVI and were followed up postoperatively with clinical and echocardiographic assessment. Primary clinical endpoint was all-cause mortality, as defined by the criteria proposed by the Valve Academic Research Consortium 2.
Results
In total, 292 patients were included (male: 50.2%, mean age: 80±7.6 years) in our study. Of these, 109 (37.5%) underwent PPI simultaneously or shortly after TAVI. The median follow-up period was 27.3 In this period, all-cause mortality showed no significant difference between patients with and those without PPI after TAVI (log-rank p=0.756), even after excluding patients with a pre-existing pacemaker from the analysis. Subgroup analysis also showed no difference in survival between patients with low ejection fraction (<50%) and those with preserved (≥50%) receiving a permanent pacemaker after TAVR (log-rank p=0.269). Taking into consideration factors that were found to associate to PPI in univariate analysis (pre TAVI - ejection fraction, pulmonary artery systolic pressure and New York Heart Association functional class) in a multivariate model, pre TAVI pulmonary artery systolic pressure was found to be an independent predictor of peri-procedural PPI [Exp(B): 0.977, 95% Confidence Interval: 0.957–0.998, B=−0.023, p=0.029]. Pre-TAVI conduction abnormalities and the degree of aortic annulus calcification, as assessed by computed-tomography, were not found to predict PPI after TAVI.
Conclusion
PPI following TAVI was not associated with survival at 27 months of follow-up, independently from the pre TAVI ejection fraction.

Abstract
Abstract
Introduction
Transcatheter aortic valve implantation (TAVI) has become the standard of care for high-risk and inoperable surgical patients and a valid alternative in intermediate-risk patients with severe aortic stenosis.The DIRECT trial (Predilatation in Transcatheter Aortic Valve Implantation Trial) was a multicenter, randomized, clinical trial designed to evaluate the safety and efficacy of TAVI with or without balloon aortic valvuloplasty (BAV) in patients with symptomatic, severe aortic valve stenosis.
Purpose
To compare the one year echocardiographic findings among patients, who underwent TAVI using a self-expanding valve with or without BAV.
Methods
A total of 171 patients with severe aortic stenosis were randomly assigned at 4 tertiary centers to undergo TAVI with the use of self-expanding prostheses with (pre-BAV) or without pre-dilatation (no-BAV). Follow up transthoracic echocardiography was performed 1 year after TAVI.
Results
Of 171 patients, 86 patients were randomized to pre-BAV group and 85 to no-BAV group. One year echocardiographic follow up was available in 146 patients. In one year follow up there was no significant difference between pre-BAV and no-BAV group in aortic valve area (1.84±0.39cm2 vs. 1.85±0.44cm2, p=0.79), peak aortic valve gradient (15.95±9.97 mmHg vs. 14.51±6.60 mmHg, p=0.35), mean aortic valve gradient (8.37±5.01 mmHg vs. 7.99±4.04 mmHg, p=0.64), aortic valve peak velocity (1.90±0.51 m/s vs. 1.80±0.42m/s, p=0.24), ejection fraction (54.19±8.36% vs. 53.19±9.58%, p=0.52) and pulmonary artery systolic pressure (41.86±14.34 mmHg vs. 40.71±12.40 mmHg, p=0.64). The incidence of moderate or severe paravalvular regurgitation (PVL) in 1 year follow up was 6.2% without significant difference between the 2 study groups (5.7% in the no-BAV group vs. 6.6% in the pre-BAV group, p=0.83).
Conclusions

Abstract
Introduction
The DIRECT trial (Predilatation in Transcatheter Aortic Valve Implantation (TAVI) Trial) was a multicenter, randomized, clinical trial designed to evaluate the safety and efficacy of TAVI with or without balloon aortic valvuloplasty (BAV) in patients with symptomatic, severe aortic valve stenosis.
Purpose
To investigate by echocardiography the functional changes of self-expanding prosthetic valves during the first year after TAVI with or without BAV.
Methods
One hundred seventy one consecutive patients with severe aortic stenosis were enrolled at 4 centers and randomized to TAVI using self-expanding prostheses with (pre-BAV) or without pre-dilatation (no-BAV). Transthoracic echocardiography was obtained at baseline, 30 days and 1 year after TAVI.
Results
Of 171 patients, 86 patients were randomized to pre-BAV group and 85 to no-BAV group. Over the one year, 7 (4%) patients died and in 18 (10%) there was no available paired 30 day/1 year echo. At baseline echocardiography the peak and mean aortic valve gradient and the aortic valve area (AVA) in no-BAV group were 77.31±22.56 mmHg, 47.23±14.98 mmHg and 0.69±0.16cm2 and in pre-BAV group 81.97±23.17 mmHg, 49.39±14.78 mmHg and 0.65±0.15cm2 respectively. One year after TAVI, patients in no-BAV and pre-BAV group showed stable peak and mean aortic valve gradients similar to those at 30 days (from 16.36±7.88 to 14.51±6.6 mmHg vs. 17.17±8.88 to 15.95±9.97 mmHg and from 8.87±4.23 to 7.99±4.04 mmHg vs. 9.39±4.79 to 8.38±5.02 mmHg respectively, P<0.001 vs. baseline). The AVA was similarly stable in one year follow up in no-BAV group (from 1.85±0.43cm2 to 1.85±0.44cm2, P<0.001 vs. baseline) and in pre-BAV group (from 1.86±0.49cm2 to 1.84±0.39cm2, P<0.001 vs. baseline). The incidence of moderate or severe paravalvular regurgitation remained unchanged in both groups (from 4.7% to 5.7% in no-BAV group and from 5.8% to 6.6% in pre-BAV group).
Conclusions
In both pre-BAV and no-BAV groups the improvement in hemodynamics of self-expanding prosthetic valves remained durable during the one year echocardiographic follow up assessment.

Abstract
Abstract
Introduction
The DIRECT trial (Predilatation in Transcatheter Aortic Valve Implantation Trial) evaluated in a randomized fashion the safety and efficacy of direct (without balloon pre-dilatation) implantation of a self-expanding valve in all comers undergoing TAVI.
Purpose
To investigate the impact of direct implantation of a self-expanding valve on one-year clinical outcomes.
Methods
DIRECT trial randomized consecutive patients with severe aortic stenosis at 4 tertiary centers to undergo TAVI with the use of self-expanding prostheses with (pre-BAV) or without pre-dilatation (no-BAV). The primary endpoint was device success according to the VARC-2 criteria. Secondary endpoints included periprocedural mortality and stroke, new permanent pacemaker implantation and vascular complications.
All cause death, cardiac death, stroke and heart failure hospitalizations were recorded at one year and compared between the two groups using Kaplan-Meier plots.
Results
In total 171 patients were randomized in 4 centers. In the intention to treat analysis 86 patients were randomized to the pre-BAV group and 85 patients to the no-BAV TAVI group.
The device success according to the VARC-2 criteria was non-inferior in the no-BAV group compared to the pre-BAV group (65/85 - 76.5% for no-BAV versus 64/86 – 74.4% for pre-BAV, mean difference = 2.1%, 90% CI: −8.9 to 13). In the no-BAV group 25 (29.4%) patients underwent post balloon dilatation and in the pre-BAV group 13 patients (15.1%) (p=0.03).
At one year 4 deaths were recorded in pre-BAV group (4.7%) and 3 deaths in no-BAV group (3.5%). There was no difference in Kaplan-Meier plots between the two groups in all-cause mortality (log-rank p=0.72, figure). Similarly, there was no difference in one-year incidence of stroke (1 in pre-BAV and 2 in no-BAV group, log-rank p=0.55), cardiac death (log-rank p=0.66), non-cardiac death (log-rank p=0.98) and heart failure hospitalizations (1 in pre-BAV versus 3 in no-BAV group, log-rank p=0.31). Lastly, there was no difference in the incidence of permanent pacemaker implantation between the two groups at one year (27/67 in no-BAV group versus 20/69 in pre-BAV group, log-rank p=0.24)
Conclusions
Direct transcatheter aortic valve implantation is non-inferior to the procedure with pre-dilatation in self-expanding valve. Despite the overall low rate of events, direct procedure has no impact on clinical outcomes at one year.

Abstract
Abstract
Microwave radiometry (MWR) has been applied successfully in the evaluation of carotid atherosclerosis, measuring reliably temperature heterogeneity of atherosclerotic plaques. Recent studies have shown an association between increased carotid temperature heterogeneity (ΔT) detected by MWR and cardiovascular events. Vulnerable plaques of the coronary arteries, share common characteristics such as the thin cap fibrous cap, that make the prone to rupture in the presence of stimulus such as shear stress or inflammation. Optical coherence tomography (OCT) is an imaging method, by which the fibrous cap and the presence of plaque rupture can be accurately in vivo visualized.
Purpose
To evaluate the impact of carotid temperature heterogeneity on the culprit plaque morphology on patients presenting with acute myocardial infarction.
Method
A total of 37 patients undergoing percutaneous coronary intervention (PCI) for an acute myocardial infarction who had an identifiable de novo culprit lesion in a native coronary artery, were enrolled in this study. All patients underwent PCI and Optical Coherence Study (OCT) within 12 hours since symptom onset. The OCT study was performed according to the standard techniques and acquired images were analyzed by 2 independent investigators., After the completion of the PCI all patients underwent MWR of both carotid arteries and ΔT was defined as maximal temperature detected along each carotid artery minus minimum.
Results
Thirty four patients with acute myocardial infarction 21 with STEMI (61.76%) and 13 (38.23%) with NSTEMI were included in the study. Thin cap fibroatheroma (TCFA) was present in 31 patients (91.1%), while all ruptured plaques had a TCFA compared to 11 TCFA (78.57%) observed in plaques that had no rupture (p=0.03). HsCRP was significantly increased in ruptured plaques compared to non ruptured ones (14.41±4.02 versus 9.9±2.5, p<0.005). Mean ΔT was significantly increased in ruptured plaques compared to no ruptured ones (1.01±0.31 versus 0.51±0.14°C, p<0.005), as well as in plaques with TCFA compared to those without a TCFA (0.82±0.37 versus 0.60±0.05°C, p=0.001). In the multivariate analysis DM, hsCRP, and ΔT were entered from which DM (OR 4.12; 95% CI 0.77–22.07; P=0.07) and ΔTau ((OR for 0.1°C increase 1.43; 95% CI 1.03–1.98; P=0.03) remained in the final model, with ΔT being the only variable independently associated with the presence of TCFA. Similarly regarding plaque rupture, STEMI, hsCRP, and ΔT were entered in the multivariate analysis from which hsCRP (OR 1.51; 95% CI 0.99–2.28; P=0.051) and ΔTau ((OR for 0.1°C increase 3.40; 95% CI 1.29–8.96; P=0.013) remained in the final model, with ΔT being the only variable independently associated with the presence of rupture.
Conclusions
Carotid thermal heterogeneity is associated with TCFA and plaque rupture in patients with acute myocardial infarction.

Abstract
Abstract
Background
Familial hypercholesterolemia (FH) syndromes constitute an important risk factor for premature atherosclerosis. Microwave radiometry (MWR) assess non-invasively carotid artery temperatures reflecting inflammation. Recent data support that statin therapy, that constitutes the cornerstone for the treatment of FH, reduces systemic inflammation.
Purpose
To investigate the impact of statin therapy either with simvastatin or with combination simvastatin plus ezetimibe on carotid artery temperatures.
Methods
Consecutive patients with diagnosis of either heterozygous hypercholesterolemia (hFH) or combined hyperlipidemia (FCH) not under statin therapy for at least 6 months were included in the study. FH pts were assigned to either simvastatin 40 mg or simvastatin 40 mg plus ezetimibe 10mg according to the discretion of the physician. FH patients who refused statin therapy were used as control group for the assessment of statins effect. In all subjects, common carotid intima-media thickness (ccIMT) was measured in the last 2 cm of the far wall of both common carotids close to the carotid bifurcation and ΔT (maximum-minimum) temperature measurements were performed across each carotid during MWR evaluation. Examinations were performed at baseline and after 6 months. Blood's lipid profile was also obtained in all patients.
Results
In total 115 patients were included in the study. Of them 40 patients received simvastatin (19 hFH and 11 FCH), 41 simvastatin + ezetimibe (31hFH and 10 FCH) and 34 (21 hFH and 13 FCH) no statin. There was no difference at baseline in ccIMT and ΔT measurements between hFH and FCH patients (0.10±0.03 vs 0.10±0.02, p=0.74 and 0.88±0.38 vs 0.84±0.32, p=0.52, respectively). Patients who refused statin therapy did not show any reduction in ccIMT and ΔT measurements between baseline and follow up (ccIMT: 0.10±0.02 vs 0.09±0.02, p=0.06 and ΔT: 0.72±0.26 vs 0.70±0.26). In contrast, there was a significant reduction in ccIMT and ΔT for patients under both simvastatin (0.10±0.03 vs 0.09±0.01, p=0.004 for ccIMT and 0.83±0.34 vs 0.63±0.24, p=0.04 for ΔT) and simvastatin + ezetimibe therapy (0.11±0.03 vs 0.09±0.02, p<0.001 and 1.00±0.38 vs 0.69±0.23, p<0.001 for ΔT). Patients under combination therapy reduced more significantly their carotid artery temperatures compared to patients under simvastatin monotherapy or patients without statin (−0.31±0.46 vs −0.2±0.40 vs −0.01±0.37, ANOVA p=0.04, Figure 1).
Conclusions
Both simvastatin and simvastatin + ezetimibe therapy among the beneficial effect on IMT, reduced carotid wall inflammation in FH pts.

All patients underwent PCI and Optical Coherence Study (OCT) within 12 hours since symptom onset. The culprit lesion of the angiogram was clearly identified by a combination of ECG, wall motion abnormalities seen in cardiac ultrasound, and coronary angiogram. The OCT study was performed using the LightLab OCT wire, and acquired images were analyzed by 2 independent investigators using previously validated criteria for OCT plaque characterization. After the completion of the PCI all patients underwent MWR of both carotid arteries and ΔT was defined as maximal temperature detected along each carotid artery minus minimum.
Results
Thirty four patients with acute myocardial infarction 21 with STEMI (61.76%) and 13 (38.23%) with NSTEMI were included in the study. STEMI patients had more ruptured plaques compared to NSTEMI patients (71.41 versus 38.46%, p=0.053). Thin cap fibroatheroma (TCFA) was present in 31 patients (91.1%), while all ruptured plaques had a TCFA compared to 11 TCFA (78.57%) observed in plaques that had no rupture (p=0.03). HsCRP was significantly increased in ruptured plaques compared to non ruptured ones (14.41±4.02 versus 9.9±2,5, p<0.005).

Conclusions
Carotid thermal heterogeneity is associated with the presence of plaque rupture in patients with acute myocardial infarction. Further studies are needed in order to assess the possible prognostic impact of carotid ΔT on such population.

Abstract
Abstract
Background/Introduction
Revascularization of the proximal segment of left anterior descending artery (pLAD) demonstrates an additional prognostic significance in survival for patients with multivessel disease. It is also indicated for symptomatic relief in patients with stable angina who are receiving optimal medical treatment in the presence of limiting angina or angina equivalent. Both coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) are still commonly needed as therapeutic options for pLAD disease.
Moreover, Everolimus-eluting stents (EES) have demonstrated superiority in safety and efficacy among other types of second or new generation drug-eluting stents.
Purpose
We aim to evaluate the long-term outcomes of PCI with EES compared to CABG surgery with left internal mammary artery, in patients with stable angina and an isolated single vessel pLAD disease.
Methods
The sample consisted of 824 patients with isolated pLAD and chronic stable angina; 445 participants were included in the EES-PCI group, and 379 were included in the CABG group. The study's primary endpoint was the occurrence of major adverse cardiac events (MACEs), namely, cardiac death, myocardial infarction (MI) not attributed to a non-target vessel and target lesion revascularization as a composite index. Secondary endpoints were Patient-Related Outcome (PRO; a composite index of all-cause mortality, any MI related to any coronary artery, any revascularization conducted to any coronary artery), individual components of MACEs, recurrence of stable or unstable angina or a nonfatal arrhythmia and disease progression of other lesions. For the comparisons between the two groups, chi-square tests and Fisher's exact tests, were used, as appropriate.
Results
During the 4.6 years of follow-up period, no statistically significant difference was observed between the two study groups in respect to the primary endpoint MACE (8.1% versus 7.4%, p=0.71). Concerning secondary endpoints, repeat revascularization (3.6% versus 2.9%, p=0.58), cardiac death (2.9% versus 3.2%, p=0.84), MI (1.6% versus 1.3%, p=0.76) and PRO (16.9% versus 17.7%, p=0.76) did not significantly differ between the two groups. Recurrence of angina was more frequent in the EES-PCI group (14.9% versus 8.4%, p=0.005) even though higher Class of angina was found less common in EES patients than in CABG patients (p<0.001). Patients treated with EES-PCI had lower rates of onset of arrhythmias compared to those treated with CABG (6.3% versus 11.9%, p=0.005). Finally, revascularization in other than target lesion was more frequent in the stent than in the surgery arm (6.3% versus 3.2%, p=0.04); as a consequence, higher rates of revascularization in any vessel was recorded in the PCI group than the CABG one (9.9% versus 5.8%, p=0.03).
Conclusion
PCI with EES seem to have similar long-term clinical outcomes compared with CABG in patients with isolated pLAD disease.

Abstract
Abstract
Background
Transcatheter aortic valve implantation (TAVI) has seen an unprecedented rise in the past decade and has become the gold-standard therapy for inoperable, high- and intermediate-risk patients with aortic valve stenosis.
Purpose
To investigate the long-term clinical outcomes (5-year survival and beyond) of patients undergoing TAVI.
Methods
Consecutive patients who underwent TAVI with a self-expanding valve between 2012 - 2015 were included in the study. Patients with bicuspid valves and valve-in-valve procedures were excluded. Clinical follow-up was performed at specified time intervals (30-day post TAVI and yearly thereafter). The primary endpoint of this study was to evaluate survival rates in the long-term (≥5 years). Secondary endpoints were echocardiographic findings and clinical status at 5 years. All endpoints were considered as per the VARC-2 criteria and the latest consensus documents.
Results
In total, 267 patients were included in the study. Complete follow-up was complete in 189 (70%) patients. The mean age at implantation was 80.71±6.81 years, 129 (48%) were female, mean logistic EuroSCORE was 24.28±8.64% and 73% of patients were at NYHA Class III. The median follow-up was 4.0±1.5 years.
Before the procedure, ejection fraction (EF) was 49.92±9.37%, mean gradient was 48.83±14.68mmHg, pulmonary artery systolic pressure (PASP) was 44.31±12.72mmHg and aortic valve area was 0.98±5.02cm2.
All patients received the self-expanding valve (mean valve size was 27.60±2.12mm), with the majority of them undergoing transfemoral TAVI (71%). Predilation was performed in 77% of the population and post TAVI dilation was performed in 20%.
Compared to pre TAVI values, EF was higher at 50.66±9.37% (p=0.041), mean gradient was lower at 9.41±4.65mmHg (p<0.001), PASP was lower at 41.55±9.93mmHg (p=0.005) and aortic valve area was higher at 1.69±0.81cm2 (p<0.001) post TAVI.
At the end of the fifth year, 160 (60%) patients were alive. Mean survival post TAVI was 32 months (median: 32.2 months, range: 0–91.2 months) and the majority of deaths were non-cardiac in nature (78%). Also, 43% patients of patients were at NYHA Class I, 50% were at NYHA Class II and 7% were at NYHA Class III. At multivariate analysis, sole independent predictor of death at 5 years was baseline PASP levels (OR 1.027, 95% CI: 1–1.054, p=0.049).
Conclusion
Transcatheter aortic valve implantation offers a viable solution for aortic stenosis patients and long-term results beyond 5 years are reassuring. Further studies are necessary in order to shed a light for very long-term outcomes.

Abstract
Abstract
Background/Introduction
The study of arterial properties in patients with aortic valve stenosis who undergo transcatheter aortic valve implantation (TAVI) remains challenging and results so far seem equivocal.
Purpose
We sought to investigate the acute and long-term effect of TAVI on arterial stiffness and wave reflections opting for a global approach.
Methods
We enrolled 90 patients (mean age 80.2±8.1 years, 50% males) with severe symptomatic aortic stenosis undergoing TAVI. Arterial stiffness was assessed by both carotid-femoral and brachial-ankle pulse wave velocity (cfPWV and baPWV). Augmentation index corrected for heart rate (AIx@75), an index of wave reflections, and central pressures were assessed with arterial tonometry. Measurements were conducted at baseline, after the procedure and at 1 year.
Results
Immediately post-TAVI there was a statistically significant increase in arterial stiffness (7.5±1.5 m/s vs 8.4±1.9 m/s, p=0.001 for cfPWV and 1,773±459 cm/s vs 2,383±645 cm/s, p<0.001 for baPWV) despite no change in systolic blood pressure. At 1-year follow-up, TAVI was still associated with an increase in arterial stiffness compared to pre-TAVI (7.5±1.5 m/s vs 8.7±1.7 m/s, p<0.001 for cfPWV and 1,773±459 cm/s vs 2,286±575 cm/s, p<0.001 for baPWV) but not to post-TAVI values. We also observed a decrease in AIx@75 (32.2±12.9% vs 27.9±8.4%, p=0.016) post-TAVI that was attenuated at 1 year (32.2±12.9% vs 29.8±9.1%, p=0.38).
Conclusions
Our study shows that after TAVI the arterial system exhibits an increase of stiffness in response to the acute relief of the obstruction, which is retained in the long term. Our findings further elucidate the immediate and long-term hemodynamic changes of TAVI to the aorta that may entail prognostic role in this growing population.

Abstract
Abstract
Background
Electrocardiographic (ECG) strain has been linked to excess cardiovascular morbidity and mortality in asymptomatic patients with aortic stenosis.
Purpose
We aim to determine the differential impact of baseline ECG-strain on long-term mortality after transcatheter aortic valve implantation (TAVI).
Methods
Patients with severe and symptomatic aortic stenosis (effective orifice area [EOA]≤1cm2), who were scheduled for TAVI with a self-expanding valve between May 2015 and May 2018 were consecutively enrolled. Left ventricular strain was defined as the presence of ≥1mm convex ST-segment depression with asymmetrical T-wave inversion in leads V5 to V6 on baseline ECG. Patients were excluded, if they had bundle branch block or a permanent pacemaker at baseline. Baseline parameters were compared, and multivariate Cox proportional hazard regression models were generated to assess outcome difference. The primary clinical endpoint was cumulative mortality defined according to the criteria proposed by the Valve Academic Research Consortium-2.
Results
Of the 171 patients screened, 56 patients were excluded due to left bundle branch block or paced rhythm. In the 115 included patients (mean age: 81.4±7), 36 patients (31.3%) had strain pattern on pre-TAVI ECG. There were no differences in baseline characteristics between the two groups. During a median follow-up of 2.32 years (IQR 1.62 to 3), 11 patients (9.6%) reached the primary clinical endpoint. Patients in the strain group had higher incidence of all-cause mortality compared to patients without left ventricular strain (25% vs 2.5%, χ2=14.4, p<0.001). Kaplan-Meier survival analysis showed a significantly decreased cumulative probability of survival at 3 years in patients with LV-strain compared with patients without LV-strain (log-rank p=0.002, Figure 1). In the multivariate analysis, left ventricular strain [Exp(B): 8.952, 95% Confidence Interval (CI): 1.215–65.938, B=2.192, p=0.031] and QRS duration [Exp(B): 1.058, 95% CI: 1.022–1.095, B=0.056, p<0.001] were found to be independent predictors of all-cause mortality after TAVI.
Conclusion
Baseline ECG left ventricular strain was an independent predictor of long-term mortality post TAVI. Systematic strain measurements might aid in risk-stratifying patients scheduled for TAVI.

Abstract
Abstract
An 18-year-old asymptomatic patient with a cardiac background of ventricular septal defect (VSD) and bicuspid aortic valve diagnosed in early childhood, was referred to our Adult Congenital Heart Disease (ACHD) outpatient clinic for routine assessment. Imaging by transthoracic echocardiography and Cardiac Magnetic Resonance (CMR) showed a well-developed multilobulated appendiform saccular formation (34x20mm) arising from the right ventricular side of the membranous septum inferior to the anterior aortic cusp and just beneath the septal leaflet of the tricuspid valve, protruding into the right ventricular outflow tract and the body of right ventricle. The fibrous quality and the absence of myocardium in this structure led to the formation of an aneurysm of the membranous septum (AMS) with the characteristic outpouching or ‘windsock’ appearance from its distention during ventricular systole (Figure). There was no shunt between the ventricles. The aortic valve was true bicuspid with severe aortic regurgitation and an eccentric jet towards the anterior leaflet of the mitral valve. The left ventricle was dilated with preserved systolic function. On the basis of the above information the Heart Team decided for surgical management.Both the presence of a true bicuspid valve (embryologically linked to VSD) as well as the pre-existing left-to-right shunting (until the spontaneous VSD closure) seem to have contributed to aortic valve dysfunction in this case. An interesting physical phenomenon concerning fluid dynamics, known as the ‘Venturi effect’, occurs in patients with ‘aneurysmal transformation’ of the ventricular septum, where the VSD becomes smaller creating thus a low-pressure zone that affects the adjacent aortic valve cusp, causing prolapse and, hence, aortic valve regurgitation.
Non-invasive imaging evaluation of patients with AMS is required for optimal diagnosis and treatment as well as for follow-up examinations. Echocardiography is an effective tool for diagnosing AMS, mainly as an incidental finding in asymptomatic subjects whereas CMR is capable of three-dimensional anatomical assessment and provides functional data about the blood flow into the aneurysm and integrity of the ventricular membranous septum.

Abstract
Abstract
Background
Transcatheter aortic valve replacement (TAVR) is often followed by conduction abnormalities, leading to a permanent pacemaker implantation (PPI). Data regarding the clinical impact of PPI following TAVR is yet to be established.
Purpose
To determine the effect of PPI after TAVR on long-term survival.
Methods : Patients with severe and symptomatic aortic stenosis [effective orifice area (EOA)≤1cm2] referred for TAVI at our institution were consecutively enrolled. Prospectively collected demographic, laboratory and echocardiographic data were retrospectively analyzed. Patients were stratified into two groups according to the need for PPI after TAVR and were followed up postoperatively with clinical and echocardiographic assessment. Primary clinical endpoint was all-cause mortality, as defined by the criteria proposed by the Valve Academic Research Consortium2.
Results : In total, 276 patients were included (male : 48.9%, mean age : 80 ± 7.5years) in our study . Of these, 107 (38.8%) underwent PPI simultaneously or shortly after TAVR. The median follow-up period was 26.6 [min. 0, max 116] months. In this period, all-cause mortality showed no significant difference between patients with and those without PPI after TAVR (log-rank p = 0.862). Subgroup analysis also showed no difference in survival between patients with low ejection fraction (<50%) and those with preserved (≥50%) receiving a permanent pacemaker after TAVR (log-rank p = 0.360). Including factors that were found to associate to PPI in univariate analysis (pre TAVR - ejection fraction, pulmonary artery systolic pressure and New York Heart Association functional class) in a multivariate model, pre TAVR pulmonary artery systolic pressure was found to be an independent predictor of peri-procedural PPI [Exp(B) : 0.974, 95% Confidence Interval : 0.953- 0.995, B= - 0.027, p= 0.015].
Conclusion : PPI following TAVR was not associated with survival at 26 months of follow-up, independently from the pre TAVR ejection fraction.

Abstract
Abstract
Background
Persistent severe pulmonary hypertension (PH) is considered to negatively affect early and late outcomes of patients undergoing aortic valve surgery. There is limited data however, cincerning the incidence of persistent PH after transcatheter aortic valve replacement (TAVR) and its impact on outcome is limited.
Purpose
We sought to investigate the impact of persistent PH on clinical outcomes of patients undergoing TAVR with a self-expanding valve.
Methods
Consecutive patients with severe symptomatic aortic stenosis scheduled for TAVR in our tertiary center were included in the study. Prospectively collected data before and after TAVR were retrospectively analyzed in all patients. Severe PH was defined as systolic pulmonary arterial pressure (sPAP) ≥45mmHg as assessed by echocardiography. For analysis purposes, patients with a sPAP decrease after TAVR to below 45mmHg were compared to patients with persistent PH following TAVR. All outcomes were evaluated according to the VARC-2 criteria.
Results
In total, 258 patients were included in this study (mean age 80.06 ± 7.50 years old, logEuroscore 24.50 ± 9.70%, NYHA III/IV Class 98.6%). Of these, 149 (57.8%) had sPAP less than 45mmHg and 109 (42.2%) had sPAP above or equal to 45mmHg at baseline. Patients with severe PH were older (81.1 ± 7.0 vs 79.1 ± 7.7, p = 0.034), presented with higher logEuroscore (26.9 ± 9.3% vs 22.5 ± 9.9%, p< 0.001), lower ejection fraction (47.9 ± 9.3% vs 52.2 ± 8.5%, p< 0.001) and higher rates of at least moderate mitral regurgitation (36.7% vs 16.2%, p = 0.002) compared to the group without PH. After TAVR, 161 (62.4%) patients had sPAP less than 45mmHg and 97 (37.6%) had sPAP above 45mmHg. There was a significant decrease of 2.4 ± 12.2mmHg in sPAP post TAVR (p < 0.01). Multivariable analysis (univariate analysis: age, logEuroscore, pre TAVR mitral regurgitation, pre TAVR ejection fraction below 40%) identified pre TAVR ejection fraction below 40% to be the most powerful predictor for persistent PH after TAVR (odds ratio 2.4, 95% confidence interval 1.0.9 – 5.26, p = 0.028). During a mean follow up period of 26.6 ± 26.8, the presence of pre TAVR severe PH was not found to be predictive of cumulative mortality[Hazard Ratio(HR) : 1.57, 95% Confidence Intervals (CI) 0.92 – 2.66, p = 0.09). However, in the same follow up period, patients with persistent PH after TAVR had higher cumulative risk of death compared to patients with sPAP < 45mmHg after TAVR (Hazard Ratio 0.49, 95% Confidence Intervals 0.29-0.82, p = 0.007) (Figure).
Conclusions
Our data suggest that TAVR is associated with a significant reduction in sPAP. Persistent PH post TAVR seems to be a predictor of higher cumulative mortality post TAVR.

Abstract
Abstract
A 72-year-old female patient with a past medical history of severe mitral regurgitation, atrial fibrillation and embolic cerebrovascular events was admitted to our institution. The patient was under optimal medical therapy and complained for progressive worsening of activity-related dyspnea with limitation of physical activity (NYHA III).
Transthoracic echocardiography showed the presence of severe mitral regurgitation with a central jet. There was prolapse of both mitral valve leaflets and interestingly the anterior leaflet presented systolic anterior motion (SAM) at the same time. There was no significant left ventricular outflow tract obstruction (LVOT). Further evaluation of the regurgitant mitral valve with a transesophageal echocardiography (TOE) confirmed the above findings and the mechanism of MV regurgitation was attributed to prolapse in addition to SAM of an elongated anterior leaflet. Laboratory test showed elevated NT-pro-BNP levels. A coronary angiography was performed and excluded significant coronary artery disease.
The findings were assessed by our institution’s HEART TEAM and, in the presence of high surgical risk (LogEuroscore 32,76%), a decision for transcatheter mitral valve repair with a Mitral Clip implantation was taken. The Mitral Clip was succesfully implanted with immediate significant reduction of the regurgitant jet and no signs of stenotic behavior of the repaired valve. There was only mild mitral valve regurgitation. Notably, after the procedure there was elimination of the SAM and no LVOT obstruction (Figure). In accordance to the echocardiography findings, the patient demonstrated a significant clinical improvement and was discharged home 1 day after the procedure. Mitral clip implantation in this case showed improvement of the MR by reducing the SAM of the mitral valve.

Abstract
Abstract
Background
The presence of concomitant mitral regurgitation (MR) is a common issue in patients with severe aortic stenosis and negatively affects patient outcome. Available data regarding MR reduction due to aortic gradient reduction and left ventricular reverse remodeling after transcatheter aortic valve implantation (TAVI) are contradictory.
Purpose
To investigate the prognostic impact of both pre- and post-procedural MR in patients undergoing TAVI.
Methods
Patients with severe and symptomatic aortic stenosis stenosis [effective orifice area (EOA)≤1cm2] referred for TAVI at our institution were consecutively enrolled. Prospectively collected demographic, laboratory and echocardiographic data were retrospectively analyzed. Patients were stratified into two groups according to MR severity : ≤ grade 1 were defined as non-significant and ≥ grade 2 as significant. Change in MR was determined by comparison between baseline and 30-day echocardiogram. Primary clinical endpoint was all-cause mortality, as defined by the criteria proposed by the Valve Academic Research Consortium2.
Results
263 consecutive patients (136 men, mean age : 80 ± 7.5 years) were included in the analysis. Significant (grade≥2) MR was present in 65 (24,7%) patients, while 198 (75,3%) patients had mild or no ( ≤ grade 1) MR. Comparing the two groups, patients with significant MR had higher systolic pulmonary pressure (51.3 ± 14.6mmHg versus 42.8 ± 11.2mmHg, p < 0.001), lower ejection fraction (47.4 ± 10.8% versus 51.2 ± 8.2%) and were more dyspnoic (New York Heart Association class IV 18.5% vesrus 2.5%, p < 0.001). The primary clinical end point occurred in 63 (24%) patients during a follow-up period of 26.6 ± 26.8 months. Patients with significant pre-procedural MR displayed greater cumulative mortality (40% versus 18.8%, p = 0.001). Perioperative risk assessed by logistic EuroScore, NYHA class and pre-procedural MR were found to significantly associate to cumulative mortality in a univariate analysis. Performing a multivariable analysis demonstrated that preprocedural MR severity could independently predict cumulative mortality [OR 2.38, B = 0.869 (95% CI 1.2 – 4.6, p = 0.01)] (Figure).
Conclusion
Significant MR is not infrequent in patients undergoing TAVI and appears to independently associate with high increased all-cause mortality.

P4358The role of the “halo sign” for the accurate quantification of atrial septal defect size by 3D TEE. Eur Heart J 2019.

Abstract
Abstract
Introduction
In patients undergoing percutaneous closure of secundum atrial septal defect (ASD), device selection is based on defect sizing by transoesophageal echocardiography (TEE) and in particular 3D measurement as well as 2D balloon-stretched derived measurements. We sought to investigate whether in patients with the presence of the “halo sign”, defined as increased tissue thickness at the edge of the ASD rims, there is an agreement between the aforementioned sizing methods with a view to avoid balloon sizing.
Methods
Consecutive patients referred to our department for single ASD closure without complex anatomy were included in our study. TEE was performed in all patients before and during the intervention. 3D datasets for ASD quantification as well as X-PLANE data sets for measurement of balloon-stretched 2D dimensions were acquired and analysed offline. During the analysis of 3D datasets, researchers were blinded to the 2D balloon-stretched measurements. Patients were stratified according to the presence of the halo sign and the correlation between 3D dimensions and balloon-derived diameter was calculated.
Results
Thirty-eight patients (14 males, 36.8%) with median age 46 [32–56] were included in our study. The “halo sign” was present in 16 patients (42.1%). In the whole study population, the median maximal and median minimal diameter measured by 3D TEE were 1.79cm [1.54–2.10] and 1.57cm [1.15–2.00] respectively while median circumference and area were 5.26cm [4.14–6.44] and 2.20cm2 [1.25–3.30] respectively. Median balloon-stretched diameter was 1.8cm [1.4–2.1]. In patients with the “halo sign” there was no significant difference between the medians of the ASD diameter calculated from 3D measurements and the 2D derived diameter (1.53cm; 1.6cm, p=0.170) whereas in patients with no “halo sign” there was significant difference (1.79cm; 2.0cm, p=0.001) (figure 1). The discrepancy between the aforementioned diameters was significantly lower in patients with the halo sign (0.04cm; 0.19cm, p=0.001). There was a good correlation between closure device size and 3D derived ASD circumference in the whole study population (R2=0.897) which was even higher in patients with the halo sign (R2=0.981). In this subgroup, the selected size of the closure device would not have differed significantly even without balloon sizing (p=0.414).
Figure 1
Conclusion
The ASD sizing by 3D echocardiography is accurate in patients with the “halo sign”. This study justifies further investigation concerning the reliability of 3D imaging in this population for the selection of the ASD device size with a view to avoid balloon sizing, decrease procedural time and thus simplify the procedure.

Abstract
Abstract
Background/Introduction
Both coronary artery bypass grafting surgery (CABG) and percutaneous coronary intervention (PCI), especially with the use of new-generation drug-eluting stents (DES), remain the most common therapeutic options of coronary artery disease, especially when the proximal segment of left anterior descending artery (pLAD) is involved. There are only a small number of studies comparing these approaches in patients with isolated lesions in LAD.
Purpose
We aim to compare the long-term outcomes of PCI with second-generation DES versus CABG surgery with left internal mammary artery, in patients with stable angina and an isolated single vessel pLAD disease.
Methods
The study population consisted of 1010 consecutive patients with stable angina and an isolated pLAD that were treated either with PCI with second generation (zotarolimus or everolimus) DES (631 patients) or with CABG surgery (379 patients). The primary endpoint was the occurrence of any major adverse cardiac event (MACE) namely cardiac death, non-fatal myocardial infarction and target lesion revascularization (using either percutaneous or surgical technique) as a composite index. Other evaluated main clinical outcomes were the components of MACE, patient-related outcome (PRO-a composite index of all-cause mortality, any myocardial infarction, any revascularization), recurrence of stable angina and arrhythmias occurrence.
Results
Lower rates of in-hospital complications (0.3% versus 12.1%, p<0.001) and shorter hospitalization [median, 1 (interquartile-range: 1–4) versus 8 (interquartile-range: 7–11), p<0.001] were recorded in the PCI group compared with the surgery arm. During the follow-up period (mean, 4.6±2.5 years), no statistical difference was observed in respect to MACE between the two study groups (10.1% versus 7.4%, p=0.14). Higher rates of repeat revascularization were detected in patients treated with PCI than those treated with CABG (5.5% versus 2.9%, p=0.05). Concerning other secondary endpoints, cardiac death (2.9% versus 3.2%, p=0.78), myocardial infarction (1.7% versus 1.3%, p=0.60), and PRO (18.9% versus 17.7%, p=0.64) did not differ in a statistically significant manner between the two techniques. Recurrence of stable angina was significantly increased in PCI (15.6% versus 8.4%, p=0.001), whereas arrhythmias occurrence was most common in the surgery group (6.3% versus 11.9%, p=0.002).
Conclusion
PCI with second-generation DES seem to have similar long-term clinical outcomes compared with CABG in patients with isolated LAD disease, highlighting the excellent long-term outcomes of both therapeutic approaches
