Hemadsorption to Contain Postoperative Cell-Free Hemoglobin and Haptoglobin Preservation for Extended Cardiopulmonary Bypass Time in Cardiac Surgery for Acute Kidney Injuries Prevention.

Introduction: Prevention of acute kidney injury during cardiopulmonary bypass (CPB) is still a challenge and has been the object of numerous studies. The incidence of acute kidney injury in the context of CPB is related to a multifactorial etiology. The role of hemadsorption in relation to cell-free hemoglobin and haptoglobin preservation is not well defined in the literature on CPB during cardiac surgery procedures.

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.

Develop of endocavitary suction device for MiECC on minimally invasive mitral valve surgery.

The minimally invasive extracorporeal circulation (MiECC) system was developed to minimize the contact of blood with air and foreign surfaces during conventional cardiopulmonary bypass (CPB). It is also aimed to reduce the inflammatory response by further increasing the biocompatibility of the components that make up the MiECC circuits. The Minithoracotomy (MTH) approach for mitral valve disease remains associated with prolonged operative times, but it is beneficial in terms of reduced postoperative complications (renal failure, atrial fibrillation, blood transfusion, wound infection), length of stay in intensive care unit (ICU) and in hospitalization, with finally a reduction in global cost.

Safety and Efficacy of PCSK9 Inhibitors in Patients with Acute Coronary Syndrome Who Underwent Coronary Artery Bypass Grafts: A Comparative Retrospective Analysis.

. The in-hospital reduction in low-density lipoprotein cholesterol (LDL-C) levels following acute coronary syndrome (ACS) is recommended in the current clinical guidelines. However, the efficacy of proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors in those patients undergoing coronary artery bypass graft (CABG) has never been demonstrated.

[Choosing a tailored prosthetic valve in cardiac surgery: what is the current role of mechanical prostheses?].

The choice of the mechanical/biological heart valve prosthesis is a topic currently debated in the light of the transcatheter prosthetic models and the results obtained/expected with the new biological valve models. Consequently, it seems that increasingly younger patients would be indicated for an implantation of a biological prosthesis. This is also in order to improve the quality of life of patients who want to avoid oral anticoagulant therapy.

Emergent Conversion to Open Heart Surgery during Transcatheter Aortic Valve Implantation: The Presence of a Rescue Team Improves Outcomes.

Objective: Transcatheter aortic valve implant (TAVI) is the gold standard for the high-surgical-risk group of patients with aortic valve disease and it is an alternative to surgery in patients at intermediate risk. Lethal complications can occur, and many of these are manageable only with emergent conversion to open heart surgery. We retrospectively evaluate the outcome of all patients undergoing TAVI in our departments and the impact of a complete cardiac rescue team to reduce 30-day mortality.

Mechanical heart valves and oral anticoagulation: a survey of the Italian Society of Cardiac Surgery.

In the latest European guidelines for the management of valvular heart disease, mechanical valve prostheses maintain a strategic role, particularly for certain patient subsets and age groups. Despite the high number of devices implanted in clinical practice, particularly in non-European and North American regions, current scientific literature and debate seem to suggest a limited use of mechanical heart valves. The cardiac surgery community seems to be highly interested in biological and transcatheter valve prostheses but less interested in mechanical heart valves, including possible strategies for self-management of anticoagulation therapy.

Infective Endocarditis After Percutaneous Device Closure of Atrial Septal Defects: Incidence, Diagnosis, and Treatment. Case Report and Literature Review.

Infective endocarditis (IE) on atrial septal defect (ASD) closure devices, while extremely rare, has been reported to be more frequent early after the procedure. We describe a case of late IE after percutaneous closure of patent foramen ovale (PFO). We also performed a literature review on this subject.

Fluoroscopy Time as a New Predictor of Short-Term Outcomes after Transcatheter Aortic Valve Replacement.

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.

Evaluation of the anatomic sinus after transcatheter aortic valve replacement.

Background: Following transcatheter aortic valve replacement (TAVI), the newly formed 'anatomic sinus'. may contribute to the formation of subclinical leaflet thrombosis (SLT).The evaluation of root geometry after TAVI is generally performed using multi-detector computed tomography (MDCT), and the role of transthoracic echocardiography (2D TTE) requires further validation.

Cardiopulmonary Bypass Settings for the Prevention of Early Hypotension During CABG.

Background: Vasoplegic syndrome is a form of vasodilatory shock that can occur before, during or after cardiopulmonary bypass (CPB). We introduce a strategy to reduce the incidence of early hypotension phenomena during Coronary Artery Bypass Graft (CABG) procedures.

Materials And Methods: In this prospective cohort study, 100 patients underwent elective CABG with two perioperative CPB settings.

Gaseous Micro-Embolic Activity and Goal-Directed Perfusion Management in a Closed System for Cardiopulmonary Bypass and Minimally Invasive Extracorporeal Circulation during Coronary Artery Bypass Grafting.

Background: Cardiopulmonary bypass (CPB) techniques are becoming minimally invasive in clinical practice. The literature describes various extracorporeal techniques which seek to eliminate air-blood contact and reduce both hemodilution and the contact surface such as in Minimally invasive Extracorporeal Circulation (MiECC) and closed systems for CPB. However, the delivery of micro-embolic activity in the circuit and metabolic activity in terms of oxygen delivery for Goal-Directed Perfusion (GDP) management, in relation to the patient's blood volume and central venous pressure, have never been related and correlated.

An annotation-independent algorithm based on electrogram characteristics to guide the identification of ventricular tachycardia isthmuses in patients with structural heart disease.

Background: Criteria such as electrograms voltage or late potentials have been largely utilized in the past to help identify areas of substrate maps that are within the ventricular tachycardia (VT) isthmus; yet their specificity and positive predictive value are quite low. The Lumipoint fractionation tool of the Rhythmia system illuminates regions with fractionated electrograms irrespective of their timing and annotation. We aimed to ascertain whether the use of this tool can rapidly identify areas within VT isthmuses from substrate maps.

Self-Expandable Prosthesis Valve Adaptation: Non-Uniform Expansion and Stent Frame Decoupling.

The incidence of non-uniform expansion in the context of the self-expandable transcatheter heart valve (THV) is little investigated, along with stent-frame decoupling, which is a form of stent adaptation, in which the lower part of the THV stent conforms to both the ellipticity of the left ventricle outflow tract and the native annulus while maintaining the higher part of the valve more circular. We analyzed post-implant multi-detector computed tomography scans in 50 patients. Prosthesis non-uniform expansion was assessed by computing the prosthesis eccentricity on 6 prespecified levels: (1) frame inflow, (2) native annulus, (3) leaflet inflow, (4) prosthesis waist, (5) leaflet outflow, and (6) frame outflow.
