Abstract Background Uncertainty exists over the optimal treatment strategy for patients presenting with acutely decompensated severe aortic stenosis (AS). The available options include a bridging balloon aortic valvuloplasty (BAV) or a direct transcatheter aortic valve implantation (TAVI). Purpose Our study compares TAVI outcomes in patients treated with two different strategies in acutely decompensated severe AS: bridged TAVI vs direct TAVI. Methods In this observational study all patients admitted with decompensated severe AS who underwent balloon aortic balloon valvuloplasty (BAV) and/or TAVI on the index admission were included. Comparison was made between bridged TAVI group (defined as initial BAV followed by TAVI) and direct TAVI group (TAVI on the index admission without bridging BAV). For this analysis we excluded patients in cardiogenic shock. Baseline characteristics, echocardiographic and periprocedural data were recorded in hospital database. Major adverse cardiovascular events (MACE) were defined as death, major bleeding, rehospitalisation for heart failure, or stroke). The follow-up data was obtained by outpatient visits and/or telephone calls. Results 178 patients with acutely decompensated AS were analysed: 58 bridged TAVI, 23 direct TAVI, 9 bridged SAVR and 88 destination BAV (defined as BAV non followed by a definite treatment). There was no statistically significant difference between bridged TAVI and direct TAVI group in mean age (83.6±6.6 vs 80.4±8.3 years), the prevalence major comorbidities (coronary, respiratory, neurological or peripheral vascular disease), renal function (eGFR 43.4±18.9 vs 45.2±20.9 ml/min/m2), the mean LV ejection fraction (53.4±13.8 vs 48.6±14.6%) or aortic valve gradient (39.4±13.0 vs 34.1±12.3mmHg), respectively. Direct TAVI patients had a higher mean surgical risk scores (STS 6.1±3.7 vs 9.1±7.0%, logES 18.8±11.5 vs 30.8±20.9%, p=0.01) and higher prevalence of significant aortic regurgitation (5% vs 43%, p=0.0001). The femoral TAVI access was used in 98% of bridged and 78% of direct TAVI patients (p=0.006). The estimated 1-year survival and 1-year MACE-free survival did not differ significantly between the bridged TAVI and direct TAVI groups (86.8% vs 78.3%, p=0.20 and 79.7% vs 64.2%, p=0.11, respectively). Conclusions A large proportion of patients admitted with acutely decompensated AS were not eligible for definite treatment. There is no difference in procedural success, 1-year all-cause mortality and 1-year major adverse cardiovascular events between the bridged TAVI or direct TAVI strategies in acute decompensated aortic stenosis allowing to personalize treatment strategy for individual patient.

A Prospective Study

Background: The objective of the study was to evaluate the early outcomes and survival in patients with severe aortic stenosis associated with concentric left ventricular hypertrophy following aortic valve replacement.Methods: This is a prospective study done at SVIMS, Tirupati, from June 2014 to September 2015 evaluating out comes and survival in patients undergoing primary isolated aortic valve replacement (AVR) for severe aortic stenosis, severe aortic stenosis with mild aortic regurgitation and severe aortic stenosis with moderate aortic regurgitation.Results: A total of 40 cases 26 males and 14 females aged 18 to 60 years (mean age, 48.5±13.4 years) underwent elective AVR. Left ventricular end diastolic diameter (p=0.008) at 6 months, a statistically highly significant difference in left ventricular mass  preoperatively, at discharge, at 3rd and 6th month follow up. The difference in mean left ventricular mass index (LVMI) had declined from 244.425 to 141.100 at 6 months, showing a statistically highly significant difference in LVMI preop, at discharge, at 3rd month and at 6th month follow up.Conclusions: Patients with preoperative increase in LVMI, with large left atrial diameter carries a strong predictor of postoperative mortality for patients undergoing aortic valve surgery. We also conclude that there will be significant regression of LVMI following successful AVR. But, the decrease in LVMI is maximum during early three months and it is minimal though significant in the later course of follow up.

ObjectiveSevere aortic stenosis (AS) is one of the most serious valve conditions. Patient demography and the aetiology of AS have substantially changed in the past several decades along with a drastic improvement of surgical aortic valve replacement (SAVR) and its associated procedures. Contemporary patients with severe AS have multiple comorbidities and live much longer. We aimed to elucidate the treatment effects of SAVR on long-term outcome in propensity score (PS)-matched and the entire patient populations.MethodsWe retrospectively reviewed 570 patients with severe AS defined as an aortic valve area of 1.0 cm2 or less. Systemic differences in 39 baseline characteristics between non-SAVR and SAVR groups were adjusted using PS matching method. The endpoints included all-cause mortality and cardiovascular events that included heart failure, non-fatal stroke, syncope and acute coronary syndrome.ResultsOverall, 55% of the entire population (mean age 78 years; males 41%) were symptomatic. During 3.9 years of the median follow-up, 210 (36%) patients underwent SAVR and 231 (41%) died. Cumulative incidences of mortality and both mortality and cardiovascular events were significantly higher in the non-SAVR group than in the other group (p<0.001, each). Among 101 PS-matched pairs, SAVR correlated with a lower mortality risk (HR 0.35; 95% CI 0.21 to 0.59; p<0.001)) and mortality and cardiovascular events combined (HR 0.62; 95% CI 0.42 to 0.92; p=0.02). However, survival difference between both groups was markedly smaller among asymptomatic patients in the subgroup of matched patients.ConclusionPatients with AS undergoing SAVR exhibit a lower incidence of all-cause mortality and major cardiovascular events than those not undergoing surgical interventions, even after the baseline characteristics are balanced by the PS matching. The correlation between SAVR and survival from cardiovascular events is less evident among asymptomatic patients.

Abstract Background Relative apical sparing pattern (RASP) is thought to be associated with prognosis in patients with cardiac amyloidosis or left ventricular hypertrophy (LVH). Although almost all patients with severe aortic stenosis (AS) have LVH, little is known about the effect of transcatheter aortic valve implantation (TAVI) in patients with severe AS exhibiting a RASP. Purpose This study aimed to elucidate the effect of TAVI on left ventricular global longitudinal strain (LS; LVGLS) in patients with severe AS exhibiting a RASP. Methods Eighty-four patients who underwent transfemoral or subclavian TAVI were evaluated. They were divided into the RASP and non-RASP groups. The average apical LS divided by the sum of the average mid and basal LS values of &gt;1.0 was defined as the RASP. We analyzed the difference between pre- and post-TAVI LVGLS (ΔGLS = post-TAVI LVGLS − pre-TAVI LVGLS). Results Of the 84 patients (mean age, 84.5±3.9 years; 24 men), 15 (17.9%) exhibited a RASP. No significant difference in mean pre-TAVI LVGLS was found between the RASP and non-RASP groups (−16.6% ± 3.8% vs. −15.8% ± 3.9%). The ΔGLS in the RASP group was significantly higher than that in the non-RASP group (−0.97% ± 2.5% vs. −2.6% ± 3.0%; P&lt;0.05). Multivariate analysis revealed that relative apical longitudinal strain was an independent predictor of ΔGLS (β = 0.35, p=0.002). Conclusion Relative apical longitudinal strain was associated with LVGLS recovery. The effect of TAVI on LVGLS in patients with a RASP is inferior to that in patients without a RASP.

Abstract Background Valve-in-valve transcatheter aortic valve implantation (TAVI) has emerged as a competent alternative for the treatment of degenerated bioprosthetic valves after surgical aortic valve replacement, or during TAVI procedure as a bailout option. Herein, we report a rare case of a self-expandable Medtronic Evolut R valve into a failing Medtronic CoreValve, with the use of modern pre-TAVI imaging screening, suggesting the proper procedural design steps for so complicated implantations. Case summary A frail 78-year-old woman with a degenerated Medtronic Core Valve 26 mm bioprosthesis, implanted in 2011 due to severe aortic stenosis, was referred to our hospital due to worsening dyspnoea New York Heart Association III. The screening echocardiography documented severe aortic stenosis, while the classical risk scores were in favour of repeated TAVI (EuroSCORE II 5.67%). Computed tomography measurements and three-dimensional (3D) printing model were of great help for the proper valve selection (Medtronic Evolut R 26 mm), while the use of cerebral protection device (Claret Sentinel) was considered as a necessary part of the procedure. The simultaneous use of fluoroscopy and transoesophageal echocardiogram led to optimal haemodynamic result, confirmed by the discharge echocardiogram, with a significant clinical improvement during the first month follow-up. Discussion The main periprocedural concerns remain valve malpositioning, coronary artery obstruction, and high remaining transvalvular gradients. The multimodality pre-TAVI imaging screening may be helpful for precise procedural design. Despite the limited use of 3D models, it is necessary to adopt such tissue-mimicking phantoms to increase the possibility of optimal procedural result.

Introduction. The dramatic changes in vascular hemodynamics after transcatheter aortic valve replacement (TAVR) are well noted. However, little postprocedural data exists on the outcomes in patients with clinical arterial peripheral vascular pathology [abdominal aortic aneurysm (AAA), carotid artery stenosis (CAS), and peripheral artery disease (PAD)] undergoing TAVR for severe aortic stenosis. Setting. A single center healthcare system. Methodology. A retrospective chart review case-control study of 342 consecutive patients who underwent a TAVR for severe aortic stenosis at Sanford Health in Fargo; ND was performed to determine if preprocedural comorbid AAA, CAS, or PAD was associated with worse outcomes after TAVR. Results. Patients with preprocedural comorbid AAA, CAS, or PAD had no significant difference overall survival at 1 month (94% versus 95% p =.812), 6 months (88% versus 89% p = .847), 1 year (74% versus 83%, p =.130), or 2 years (58% versus 63%, p =.611) after TAVR. Patients with clinical arterial peripheral vascular pathology also had no significant difference in preprocedural outcomes. Conclusion. This study gives evidence to suggest that patients with a comorbid clinical peripheral arterial pathology at the time of TAVR do not have a statistically significant increase in mortality out to 2 years after TAVR and no increase in procedural complications. These results affirm the safety and feasibility of TAVR in patients with AAA, CAS, and/or PAD.
