Single suture-mediated closure system after transfemoral transcatheter aortic valve implantation: A single-center real-world experience.

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.

Accelerated stenotic flow in the left anterior descending coronary artery explains the causes of impaired coronary flow reserve: an integrated transthoracic enhanced Doppler study.

Background: Accelerated stenotic flow (AsF) in the entire left anterior descending coronary artery (LAD), assessed by transthoracic enhanced color Doppler (E-Doppler TTE), can reveal coronary stenosis (CS) and its severity, enabling a distinction between the microcirculatory and epicardial causes of coronary flow reserve (CFR) impairment.

Methods: Eighty-four consecutive patients with a CFR <2.0 (1.

Assessment and management of heart failure in patients with chronic kidney disease.

Heart failure (HF) and chronic kidney disease (CKD) are two pathological conditions with a high prevalence in the general population. When they coexist in the same patient, a strict interplay between them is observed, such that patients affected require a clinical multidisciplinary and personalized management. The diagnosis of HF and CKD relies on signs and symptoms of the patient but several additional tools, such as blood-based biomarkers and imaging techniques, are needed to clarify and discriminate the main characteristics of these diseases.

Preliminary clinical evaluation of free/total PSA ratio by the IMMULITE system.

The role of free (F) and complexed serum PSA is now under investigation. In the present study, we evaluated the clinical significance of F-PSA and F/Total (T) PSA ratio in a preliminary series of samples from 88 patients with prostate cancer (PC), 113 with benign prostatic disease (BPD), and 98 with non-prostatic disease (NP). We used the F-PSA and third generation T-PSA (DPC, Los Angeles, USA) chemiluminescent enzyme immunometric assays with the IMMULITE automated system.
