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
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.

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
Direct transcatheter aortic valve implantation has no impact on one-year prosthesis function and PVL in patients undergoing TAVI with self-expanding valve

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
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
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.

Abstract
Abstract
Cardiorespiratory response, right ventricular and global diastolic function is known to deteriorate the clinical course of patients with chronic heart failure with reduced ejection fraction (HFrEF), even under optimal treatment. In this work we sought to evaluate the impact of sacubitril/valsartan initiation in patients with chronic HFrEF in NYHA clinical status II-III, under optimal medical and invasive treatment. Methods 180 patients (85% male, mean age 62±9 years old, 60% ischemic heart failure, 73% with ICD, 45%with CRT and 45% with diabetes mellitus) in NYHA classification II-III-, who were prescribed Sacubitril-Valsartan were evaluated.
Clinical status, biochemical parameters, cardiorespiratory exercise response and bi-ventricular Doppler indices were evaluated at first visit and 6 months after. The pulsed tissue Doppler imaging of the systolic and diastolic function of mitral and tricuspid annulus was characterized by the systolic waves Smv and Stv, and the diastolic waves: Emv and Amv; E was the early filling wave in transmitral velocity. Left atrial maximal volume and global longitudinal strain of the left ventricle (GLPS) were measured. In cardiorespiratory exercise Vo2max, VE/VCO2 and Mets achieved were evaluated. All of them received b-blockers, 90% eplerenone or spironolactone, 25% ivabradine and 90% diuretic treatment. Seventy percent of them started with the dose of 50mg of sacubitril/valsartan; while 80% finally received the full dose of 200 mg bid. One third of them were on clinical status NYHA III.
Results
Eight of the patients discontinued the medication due to hypotension or renal function worsening. All patients expressed improvement in clinical status; while diuretic therapy was down titrated in all of them and discontinued in 30%. As compared with the initial examination, tricuspid annulus systolic wave velocity increased by 5% (p=0.04); maximum volume of left atrium was decreased by 6% (p=0.004); GLPS average was improved by 41% (p=0.001) and E/Emv ratio was decreased by 22% (p=0.04). Moreover, improvement in Stv was more prominent in DCM as compared to IHF patients; In cardio respiratory exercise VE/VCO2 decreased by 5% (p=0.05); while VO2 max showed a trend in improvement (p=0.06), with no difference detected between DCM and ICM patients; although there was a significant increase (47%) in METS achieved (p=0.02).
Conclusion
Sacubitril/valsartan initiation was associated with improved left diastolic function and right ventricular function, along with functional status improvement in patients with HFrEF. These finding underline the beneficial role of sacubitril/valsartan initiation on the hemodynamic course of patients with systolic heart failure and clinical status deterioration.

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
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
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.

Abstract
Abstract
Background/Introduction
The clinical importance of a hypertensive response to exercise (HRE) in subjects with high normal blood pressure (BP) is not fully elucidated, while sympathetic overactivity and arterial stiffening are linked with adverse cardiovascular prognosis.
Purpose
The aim of this study was to assess the relation of HRE with sympathetic drive as assessed by muscle sympathetic nerve activity (MSNA) and arterial stiffness in subjects with high normal BP.
Methods
42 subjects with high normal office BP [defined as office systolic BP=130–139 mmHg and office diastolic BP=85–89 mmHg (age: 53±9 years, 29 males, office BP: 134/84 mmHg, 24-hour BP: 114/72 mmHg)] with a negative treadmill exercise test (Bruce protocol) were divided into those with HRE (n=12) (peak exercise systolic BP ≥210mmHg in men and ≥190 mmHg in women) and those without HRE (n=30). Arterial stiffness was evaluated on the basis of carotid to femoral pulse wave velocity (PWV) values. In all participants sympathetic drive was assessed by MSNA estimations based on established methodology (microneurography).
Results
Subjects with a HRE compared to those without exhibited higher waist circumference (108.2±5.3 vs 94.7±9.2 cm, p=0.001) and were characterized by greater levels of carotid to femoral PWV (8.5±0.8 vs 7.0±0.9 m/sec, p<0.001) and sympathetic nerve traffic as reflected by MSNA levels (41.1±1.5 vs 32.1±1.9 bursts per 100 heart beats, p<0.001), while did not differ regarding metabolic profile and left ventricular mass index (p=NS). In the total population, peak exercise systolic BP was related to 24-h systolic BP (r=0.229, p<0.05), PWV (r=0.218, p=0.002), and MSNA (r=0.214, p<0.05). Moreover, MSNA was related to waist circumference (r=0.33, p=0.004) and office systolic BP levels (r=0.31, p<0.05) but there was no association with PWV values (p=NS).
Conclusion
In subjects with high normal BP, a HRE identifies a state of arterial stiffening and sympathetic overdrive, as reflected by increased PWV and MSNA levels respectively. These finding suggest that exercise testing provides additional clinical information regarding the vascular status and modulation of sympathetic tone in this setting.
