Background: Transcatheter aortic valve replacement (TAVR) is an almost totally cine-fluoroscopic guided procedure. The amount of radiation used during the procedure is strictly related to the ...fluoroscopy time (FT), that has already been demonstrated to be associated with outcomes and complexity of coronary procedures. The aim of our study is to demonstrate the relationship between FT and the short-term outcomes after TAVR defined by to the Valve Academic Research Consortium (VARC)-2 and -3 consensus documents. Methods: After splitting 1797 consecutive patients into tertiles of FT, the composite endpoint early safety (ES) was adjudicated according to VARC-2 and VARC-3 definitions, whereas the composite endpoints device success (DS) and technical success (TS) according to VARC-3 criteria. Results: The absence of all these outcomes (VARC-2 ES amd VARC-3 TS, DS, and ES) was significantly associated with longer FT: this association was independent from both intraprocedural complications and other intraprocedural factors linked to longer FT, and still persisted after propensity score matching analysis. Notwithstanding, after receiver operating characteristic analysis, FT had adequate diagnostic accuracy in identifying the absence of only VARC-3 TS and VARC-2 ES. Conclusion: Longer FT is related with periprocedural and short-term outcomes after the procedure, especially in those that are more challenging. A FT duration of more than 30 min has an adequate accuracy in identifying VARC-3 technical failure (TS and DS) and absence of VARC-2 ES, selecting patients who are likely to take advantage from more careful in-hospital follow-up.
Ascending aortic pseudoaneurysm is a rare pathology that could have multiple etiologies such as thoracic trauma, infection, and percutaneous or surgical procedures. In patients with aortic ...pseudoaneurysms, open surgical or endovascular interventions are always indicated, if feasible and independent of size. Several types of endovascular treatment have been reported in the literature, but they have been mostly restricted to those cases when traditional surgery has a prohibitive risk. We report the case of a 75-year-old man with a sinotubular junction pseudoaneurysm, likely developed after coronary artery bypass grafting, which was successfully treated by implanting a multifenestrated cribriform septal occluder, a device already used in few similar cases.
<Learning objective: Aortic pseudoaneurysm could be a consequence of several types of aortic injuries. In frail patients endovascular approach represents a viable option instead of surgical repair. Such percutaneous treatment has to be individualized also according to the lesion location and size, as in our case where a sinotubular junction pseudoaneurysm was successfully treated by implanting a multifenestrated cribriform septal occluder.>
Acid sphingomyelinase deficiency (ASMD)—also known as Niemann–Pick (NP) disease—is a rare, autosomal recessive disorder which is characterized by deficiency of the lysosomal enzyme acid ...sphingomyelinase (ASM), resulting in excessive storage of lipids in organs (i.e., spleen, liver, lung, bone marrow, lymph nodes, and vascular system). Only a few cases of moderate-to-severe valvular heart disease due to ASMD are described in the literature, mostly in adulthood. We report here the case of a patient with NP disease subtype B that was diagnosed during adulthood. NP disease in this patient was found to be associated with situs inversus. Specifically, a severe, symptomatic aortic stenosis was identified, and the need for surgical or percutaneous intervention was discussed. The heart team chose transcatheter aortic valvular implantation (TAVI), which was successfully performed with no complications on follow-up.
Surgical mortality risk scores, even if not properly designed and rarely tested in the transcatheter aortic valve implantation (TAVI) setting, still guide the heart team in managing significant ...aortic stenosis.
After splitting 1763 consecutive patients retrospectively based on their mortality risk thresholds, the composite endpoint early safety (ES) was adjudicated according to Valve Academic Research Consortium (VARC)-2 and -3 consensus documents.
ES incidence was higher if VARC-2 rather than VARC-3 defined. Despite only patients showing VARC-2 ES had significantly lower absolute values of all three main risk scores, these last still failed to foresee both VARC-2 and -3 ES in intermediate-risk patients. The receiver operating characteristic analysis also showed a significant correlation, but with poor diagnostic accuracy, among the three scores and only VARC-2 ES; moreover, the absence of VARC-2 ES and low-osmolar contrast media administration were identified as independent predictors of 1-year mortality and absence of VARC-3 ES, respectively. Finally, even a single complication included in the ES definition could significantly affect 1-year mortality.
Currently, the most used mortality risk scores do not have adequate diagnostic accuracy in predicting ES after TAVI. The absence of VARC-2, instead of VARC-3, ES is an independent predictor of 1-year mortality.
A comprehensive description of baseline characteristics, procedural features and outcomes related to the development of acute kidney injury (AKI) after transcatheter aortic valve implantation (TAVI) ...is reported in our research paper (Impact of contrast medium osmolality on the risk of acute kidney injury after transcatheter aortic valve implantation: insights from the Magna Graecia TAVI registry. Int J Cardiol. DOI: 10.1016/j.ijcard.2020.12.049). Three Italian heart centers were involved in this multicentric observational study. Between March 2011 and February 2019, a total of 888 patients underwent TAVI; according to the inclusion and exclusion criteria, 697 patients were included in the post-hoc analysis. This Data in Brief paper aims to report demographic, clinical, laboratory, echocardiographic, intraprocedural, periprocedural, postprocedural and follow-up data; all of them were prospectively collected from each patient's health record, whereas the analysis was performed retrospectively. Targets of this data analysis were: 1) to evaluate the impact of contrast medium (CM) osmolality on TAVI-related AKI; 2) to identify the most of risk factors involved in the development of such complication, and consequently in the occurrence of 1-year mortality; 3) to estimate the impact of CM osmolality on AKI in specific patient subgroups.
Transcatheter aortic valve replacement (TAVR) in the presence of a mechanical mitral valve (MMV) prosthesis is challenging due to the stiff mitral cage in the boundaries of the aorto‐mitral curtain. ...We describe the technique for TAVR using the ACURATE‐neo™ aortic bioprosthesis in a patient with a MMV prosthesis.
Acute kidney injury (AKI) after transcatheter aortic valve implantation (TAVI) is frequent and associated with adverse outcomes and mortality; to date, in such setting of patients there is no ...consistent evidence that either low-osmolar contrast media (LOCM) or iso‐osmolar contrast medium (IOCM) are superior to the other in terms of renal safety.
697 consecutive patients not in hemodialysis treatment who underwent TAVI (327 males, mean age 81.01 ± 5.75 years, mean european system for cardiac operative risk evaluation II 6.17 ± 0.23%) were enrolled. According to osmolality of the different iodinated CM, the population was divided in 2 groups: IOCM (n = 370) and LOCM group (n = 327). Preoperatively, 40.54% of patients in IOCM vs 39.14% in LOCM group (p = 0.765) suffered from chronic kidney disease (CKD).
The incidence of AKI was significantly lower with IOCM (9.73%) than with LOCM (15.90%; p = 0.02), and such significant difference (p < 0.001) in postprocedural change of renal function parameters persisted at discharge too. The incidence of AKI was also significantly lower with IOCM in younger patients, without diabetes, anemia, coronary artery disease history, CKD, chronic or persistent atrial fibrillation, left ventricular ejection fraction ≤35%, and in patients with low operative mortality risk scores, receiving lower amounts of dye (p < 0.05 for all). Importantly, multivariate analysis identified LOCM administration as an independent risk factor for both AKI (p = 0.006) and 1-year mortality (p = 0.001).
The use of IOCM have a favorable impact on renal function with respect to LOCM, but it should be considered especially for TAVI patients at lower AKI risk.
To comparatively assess the natural history of patients of different ages undergoing transcatheter aortic valve replacement (TAVR).
For this study, we used the YOUNG TAVR, an international, ...multicenter registry investigating mortality trends up to 2 years in patients with aortic valve stenosis treated by TAVR, classified according to 3 prespecified age groups: 75 years or younger (n=179), 76 to 86 years (n=602), and older than 86 years (n=221). A total of 1002 patients undergoing TAVR were included. Demographic, clinical, and outcome data in the youngest group were compared with those of patients 76 to 86 years and older than 86 years. Patients were followed up for up to 2 years.
Compared with patients 75 years or younger (reference group), patients aged 76 to 86 years and older than 86 years had nonsignificantly different 30-day mortality (odds ratio, 0.76; 95% CI, 0.41-1.38; P=.37 and odds ratio, 1.27; 95% CI, 0.62-2.60; P=.51, respectively) and 1-year mortality (hazard ratio (HR), 0.72; 95% CI, 0.48-1.09; P=.12 and HR, 1.11; 95% CI, 0.88-1.40; P=.34, respectively). Mortality at 2 years was significantly lower among patients aged 76 to 86 years (HR, 0.62; 95% CI, 0.42-0.90; P=.01) but not among the older group (HR, 1.06; 95% CI, 0.68-1.67; P=.79). The Society of Thoracic Surgeons 30-day mortality score was lower in younger patients who, however, had a significantly higher prevalence of chronic obstructive pulmonary disease (P=.005 vs the intermediate group and P=.02 vs the older group) and bicuspid aortic valves (P=.02 vs both older groups), larger left ventricles, and lower ejection fractions.
In the present registry, mortality at 2 years after TAVR among patients 75 years or younger was higher compared with that of patients aged 75 to 86 years and was not markedly different from that of patients older than 86 years. The findings are attributable at least in part to a greater burden of comorbidities in the younger age group that are not entirely captured by current risk assessment tools.
Peripheral artery disease (PAD) is associated with increased risk of cardiovascular events. The benefits of dual antiplatelet therapy (DAPT) vs single antiplatelet therapy (SAPT) with aspirin in ...patients with PAD remain subject of ongoing debate.
We performed a meta-analysis of studies comparing DAPT vs aspirin monotherapy in PAD. Incidence rate ratios (RR) and respective 95% confidence intervals (CI) were used as summary statistics. The primary outcome was mortality. Secondary endpoints were ischemic and bleeding outcomes. Ten studies including 65,675 patients have been included. Compared to SAPT, DAPT was associated with a significant reduction in mortality: RR, 0.89; 95% CI, 0.86–0.92; P < 0.001. Results were consistent across patients with symptomatic PAD and those undergoing bypass or percutaneous transluminal angioplasty (PTA). Similarly, DAPT significantly reduced the risk of repeat peripheral revascularizations (RR, 0.80; 95% CI, 0.69–0.92; P = 0.002). No significant increase of major bleeding complications was observed with DAPT as compared to SAPT (RR, 1.21; 95% CI, 0.87–1.68 P = 0.26).
DAPT, as compared to SAPT, significantly reduces mortality in patients with PAD, with no significant increase in bleeding complications. These findings support DAPT as the mainstay antiplatelet therapeutic regimen in patients with PAD.
