ABSTRACT
BACKGROUND: Despite the use of two crossed Perclose ProGlide™ (Abbott Vascular Devices) is the most widespread technique to close the main arterial access in transfemoral transcatheter aortic valve implantation (TF-TAVI), the safest and most effective strategy still remains much debated. AIMS: The aim of the present study was to evaluate the performance of a single Perclose ProGlide suture-mediated closure device to obtain femoral hemostasis after sheathless implantation of self-expanding transcatheter heart valves through their 14 F-equivalent fix delivery systems. METHODS: This prospective observational study included 439 patients undergoing TF-TAVI at the "Montevergine" Clinic of Mercogliano, Italy. All patients underwent hemostasis of the large-bore access using a single Perclose ProGlide with preclose technique, after sheathless implantation of self-expanding transcatheter heart valves through 14 F-equivalent fix delivery systems. A multidetector computed tomography analysis of size, tortuosity, atherosclerotic, and calcification burdens of the ilio-femoral access route was made by a dedicated corelab. Vascular complications (VCs), percutaneous closure device (PCD) failure, and bleedings were adjudicated by a clinical events committee. RESULTS: A total of 81 different VCs were observed in 60 patients (13.7%); among these, 41 (5% of patients) were categorized as major. PCD failure occurred in 14 patients (3.2%). At the logistic regression analysis, no predictors of PCD failure have been identified. CONCLUSION: This registry suggests that the use of a single suture-mediated closure device could be considered a safe and efficient technique to achieve access site hemostasis in patients undergoing TF-TAVI through 14 F-equivalent fix delivery systems.

Aims: Preliminary data on Sapien 3 valve (S3-THV) use for transcatheter aortic valve implantation have shown an increased permanent pacemaker implantation (PPMI) rate with respect to Sapien XT valve. Aim of this study was to investigate the role of S3-THV position in the left ventricular outflow tract (LVOT) on electrocardiographic changes suggestive of atrioventricular (ΔPR) and/or intraventricular (ΔQRS) conduction abnormalities and 30 days PPMI rate. Methods and results: Eighty-six consecutive patients treated with S3-THV were included in the study. All patients underwent clinical and electrocardiogram evaluation. Left ventricular outflow tract prosthesis depth was assessed by fluoroscopy and expressed quantitatively (mm) and as aorto-ventricular ratio (AVR). Eight patients (9.3%) needed PPMI at 30 days. A low AVR (≤60/40) predicted PPMI (OR = 6.09, 95% CI 1.19-31.01, P = 0.030) and resulted into higher PPMI rate, compared with higher AVR (30.0 vs. 6.6%, P = 0.017). For each millimetre increase in the LVOT prosthesis depth PPMI risk increased by 1.41 times (95% CI 1.06-1.87, P = 0.017). In patients with low AVR, ΔPR was higher than in those with higher AVR (33.4 ± 56.7 vs. 12.1 ± 19.4 ms, P = 0.021) and ΔPR was associated to LVOT prosthesis depth (ß = 0.286, P = 0.009). Furthermore, ΔPR was associated with risk of PPMI (OR = 1.03, 95% CI 1.01-1.06, P = 0.024). Conclusions: A low AVR is associated to higher ΔPR and PPMI rates. The correlation between LVOT prosthesis depth with ΔPR and higher PPMI rate suggests the need of a careful S3-THV implantation.

BACKGROUND: Acute kidney injury (AKI) after transcatheter aortic valve implantation (TAVI) is a frequent complication associated with adverse outcomes and mortality. Various scores have been developed to predict this complication in the coronary setting. However, none have ever been tested in a large TAVI population. This study aimed to evaluate the power of four different scores in predicting AKI after TAVI. METHODS: Overall, 1535 consecutive TAVI patients from the observational multicentric "Magna Graecia" TAVI registry were included in the analysis. Of the study population, 235 (15.31%) developed AKI early. The Mehran, William Beaumont Hospital, CR4EATME3AD3, and ACEF scores were calculated retrospectively. RESULTS: The patients who developed TAVI-related AKI had significantly higher absolute values of all risk scores than those who did not. The receiver-operating characteristic analysis also showed a significant correlation between these four scores and AKI, but without a significant difference among all of them (p value = 0.176). Nevertheless, based on their area under the curve values (≤0.604 for all), none had adequate diagnostic accuracy in predicting TAVI-related AKI. Importantly, multivariate analysis identified myocardial revascularization close to the TAVI procedure and implantation of self-expanding prostheses, as well as atrial fibrillation, low-osmolar contrast media administration, corrected contrast medium volume, and any transfusion (p value < 0.05 for all) as independent risk factors for AKI. CONCLUSIONS: Although high values of current AKI risk scores are significantly associated with the development of this complication, these are not sufficiently accurate. Further studies are needed so that a TAVI-dedicated AKI risk score may be created.

BACKGROUND: Surgical aortic valve replacement with a rapid deployment valve (RDV) is a relatively recent treatment option. The aim of this study was to compare the hemodynamic performance of balloon-expandable (BE)-RDVs and BE-transcatheter heart valves (THVs) in a high surgical risk and frail-elderly population. METHODS: BE-THVs and BE-RDVs were implanted in 138 and 47 patients, respectively, all older than 75 years and with a Canadian Study of Health and Aging category of 5 or above. Echocardiographic assessment was performed at discharge and six months later. RESULTS: At discharge, transprosthetic pressure gradients and indexed effective orifice area (iEOA) were similar in both cohorts. At six-month follow-up, BE-RDVs showed lower peak (14.69 vs. 20.86 mmHg; p < 0.001) and mean (7.82 vs. 11.83 mmHg; p < 0.001) gradients, and larger iEOA (1.05 vs. 0.84 cm2/m2; p < 0.001). Similar findings were also shown considering only small-sized valves. Moderate-to-severe paravalvular leakage was more prevalent in BE-THVs at discharge (14.49 vs. 0.00%; p = 0.032) and, considering exclusively small prostheses, at six months too (57.69 vs. 15.00%; p = 0.014). Nevertheless, BE-THVs determined amelioration in left ventricular ejection fraction (53.79 vs. 60.14%; p < 0.001), pulmonary artery systolic pressure (35.81 vs. 33.15 mmHg; p = 0.042), and tricuspid regurgitation severity (40.58 vs. 19.57%; p = 0.031), from discharge to mid-term follow-up. CONCLUSIONS: BE-RDVs showed better hemodynamic performance, especially when implanted in small annuli. Despite their worse baseline conditions, transcatheter patients still exhibited a greater improvement of their echocardiographic profile at mid-term follow-up.

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.
ABSTRACT
BACKGROUND: 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. METHODS: 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). RESULTS: 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). CONCLUSIONS: 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.

Mega aorta syndrome (MAS) poses a complex clinical challenge: the involvement of the ascending aorta, aortic arch, descending thoracic and abdominal aorta with extension below the origin of renal arteries requires almost total replacement of the aorta. The modality of treatment remains still controversial. Different aortic debranching techniques have been developed to re-route the origin of epiaortic and visceral vessels and achieve an optimal landing zone for implantation of subsequent endovascular grafts. We illustrate the Lupiae technique as a further evolution of the aortic debranching and hybrid repair of a mega aorta. It was developed with the purpose to exclude a very long segment of diseased aorta by implanting two or more endoprostheses between two surgically-generated landing zones. We describe a series of 27 patients treated by this hybrid three-stage mega-aorta repair; the tips and tricks discussed here facilitate a safe and effective procedure, enable treatment of frail patients and help to avoid life-threatening complications.
ABSTRACT
A 67-year-old patient with rheumatic heart valve disease had undergone two cardiac surgeries at the age of 30 years, then re-do with mitral valve replacement at 50 years. She presented with congestive heart failure and hemolytic anemia. Doppler echocardiography showed moderate-severe mitral regurgitation due to paravalvular mitral valve leak (PVML) and severe pulmonary hypertension. Transesophageal echocardiography demonstrated severe PVML secondary to a large 20 mm-long PVML defect. Due to comorbidities, the heart team deemed a third reoperation at very high surgical risk; therefore, the patient was considered most suitable for a transcatheter approach to PVML closure. Two Occlutech paravalvular leak devices were successfully delivered using a simultaneous double-transapical access with double-wire technique.

Meckel's diverticulum (MD) is considered the most prevalent congenital anomaly of the gastrointestinal tract. It may result in a number of complications including hemorrhage, obstruction, and inflammation. Obstruction of various types is the most common presenting symptom in the adult population. Loop formations with the end of an MD and adjacent mesentery constricting the distal ileum is an uncommon cause of obstruction. Axial torsion and gangrene of MD is the rarest of the complications. The correct diagnosis of complicated MD before surgery is often difficult because this condition may mimic other acute abdominal pathologies. Delay in the diagnosis of a complicated MD can lead to significant morbidity and mortality. Here we describe the case of a patient with a very rare form of acute small bowel obstruction secondary to giant torsed gangrenous MD encircling the terminal ileum. To our knowledge, this co-occurrence of axial torsion and a loop-forming mechanism of obstruction has been reported only once in English medical literature.
