Combined Treatment With Carotid Endoarterectomy and Coronary Artery Bypass Grafting: A Single-Institutional Experience in 222 Patients.

Introduction: Carotid atherosclerotic disease is a known independent risk factor of post operative stroke after coronary artery bypass grafting (CABG). The best management of concomitant coronary artery disease and carotid artery disease remains debated. Current strategies include simultaneous carotid endoarterectomy (CEA) and CABG, staged CEA followed by CABG, staged CABG followed by CEA, staged transfemoral carotid artery stenting (TF-CAS) followed by CABG, simultaneous TF-CAS and CABG and transcarotid artery stenting.

Clinical and Hemodynamic Outcomes of Rapid-Deployment Aortic Bioprostheses.

Aim of this retrospective, multicenter study was to evaluate early and mid-term clinical and hemodynamic results of patients who underwent surgical aortic valve replacement (SAVR) with Intuity rapid-deployment bioprostheses (RDB) (Edwards Lifesciences, Irvine, CA). We analyzed data from the Italian Registry of Intuity Valve (INTU-ITA registry) that is a national, real-world and independent from the industry registry. Preoperative variables were defined according to EuroSCORE and postoperative outcomes according to Valve Academic Research Consortium (VARC).

Cardiac surgery practice during the COVID-19 outbreak: a multicentre national survey.

Objectives: Healthcare systems worldwide have been overburdened by the coronavirus disease 2019 (COVID-19) outbreak. Accordingly, hospitals had to implement strategies to profoundly reshape both non-COVID-19 medical care and surgical activities.

Methods: Data from the Italian multicenter registry of aortic valve replacement with rapid-deployment bioprostheses (INTU-ITA registry) were analyzed. Patients were divided into 2 groups: full sternotomy (FS) and ministernotomy (MS).

Surgical aortic valve replacement with new-generation bioprostheses: Sutureless versus rapid-deployment.

Objectives: The aim of this retrospective multicenter study was to compare early clinical and hemodynamic outcomes of Perceval-S sutureless (Livanova, London, United Kingdom) and Intuity rapid-deployment (Edwards Lifesciences, Irvine, Calif) bioprostheses.

Methods: Data from patients who underwent isolated or combined aortic valve replacement with Perceval-S and with Intuity bioprostheses at 18 cardiac surgical institutions were analyzed. Propensity matching was performed to identify similar patient cohorts.

Isolation of clinically relevant concentrations of bone marrow mesenchymal stem cells without centrifugation.

Background: This study examined the quality of bone marrow aspirates extracted using a novel, FDA cleared method to optimally target cells from the inner cortical iliac bone surface without the need for centrifugation. This method employs small draws from a single puncture that promote only lateral flow from multiple sites (SSLM method). The study utilized the Marrow Cellutions bone marrow aspiration system (MC system) which is based on the SSLM method and compared the MC system directly to bone marrow concentrates (BMAC) generated by centrifugation of aspirates harvested with a standard aspiration needle.

Early and Mid-Term Results of Rapid Deployment Valves: The Intuity Italian Registry (INTU-ITA).

Background: Rapid deployment bioprostheses (RDBs) have been recently introduced into clinical practice for the treatment of severe aortic valve stenosis. The aim of this retrospective multicenter study was to assess early and mid-term clinical and hemodynamic outcomes of patients undergoing RDB implantation.

Methods: Data from a national registry that included patients who underwent isolated or combined aortic valve replacement with RDB in Italy were analyzed.

Spontaneous rectus sheath hematoma: The utility of CT angiography.

We described the utility of computed tomography (CT) angiography in detection of bleeding vessels for a rapid percutaneous arterial embolization of the spontaneous rectus sheath hematoma. A 70-year-old woman comes to our attention with acute abdominal pain and a low hemoglobin level. An unenhanced CT was performed demonstrating a large rectus sheath hematoma.

Full Orifice Patching without Annuloplasty for Severe Functional Tricuspid Valve Regurgitation.

Surgical treatment of severe functional tricuspid regurgitation associated with dilated right ventricle and increased chordal tethering (>8 mm) is challenging. We designed a technique where the anterior and posterior leaflets are detached from 50% of the annulus and a patch as large as the tricuspid orifice is sewn to augment the leaflets' tissue to force the coaptation with the septal leaflet. Annuloplasty is not performed, as it can only increase the chordal tethering, reducing the benefit of tissue augmentation.

Postoperative atrial fibrillation and total dietary antioxidant capacity in patients undergoing cardiac surgery: The Polyphemus Observational Study.

Objective: Postoperative atrial fibrillation is a major cause of morbidity and mortality for stroke after cardiac surgery. Both systemic inflammation and oxidative stress play a role in the initiation of postoperative atrial fibrillation after cardiac surgery. The possible association between long-term intake of antioxidant-rich foods and postoperative atrial fibrillation incidence was examined in patients undergoing cardiac surgery.

Endovascular treatment of persistent sciatic artery aneurysm with the multilayer stent.

Purpose: To describe the successful management of a symptomatic persistent sciatic artery (PSA) aneurysm using the Multilayer Aneurysm Repair System (MARS).

Case Report: A 50-year-old man with history of smoking, hypertension, and hypercholesterolemia suddenly developed pain in the buttock radiating to the left lower limb, mimicking sciatica. The ∼57×54-mm incomplete type PSA aneurysm was treated with two 14×80- and 14×60-mm MARS devices through a surgical left axillary artery access.

Implantation of a new mitral ring, adjustable during follow-up: a simplified technique.

Mitral valve repair for ischaemic mitral incompetence has a 10% rate of failure at ten year follow-up. Progressive annular dilation could play an important role. We have implanted the enCor(SQ)(TM) mitral valve repair system.

Lethal nature of ischemic gastropathy: a case report of celiomesenteric vascular insufficiency.

Celiomesenteric ischemia has an insidious onset and the non-specific symptoms are often misdiagnosed as cholecystitis or peptic ulcer disease with a consequential delay between the onset of symptoms and radiological evidence of vascular occlusive disease. A elderly man was hospitalized after a 2-3 week history of acute abdominal pain, frequent vomiting, and chronic diarrhea associated with bloody stools. Upper gastrointestinal endoscopy showed a cobblestone gastric pattern with multiple ulcerated areas and the specimens indicated focal full thickness coagulative necrosis of the mucosa.

Prospective, randomized clinical trial of the FloSeal matrix sealant in cardiac surgery.

Background: Topical hemostatic agents composed of a gelatin-based matrix and thrombin have been reported to be effective, in addition to traditional means, in terminating bleeding during cardiac operations. We compared a hemostatic matrix sealant agent (FloSeal; Baxter Inc, Deerfield, IL) with alternative topical hemostatic agents in a mixed cohort of elective cardiac and thoracic aortic operations.

Methods: Following sample size calculation, in a prospective randomized study design, 209 patients were treated with FloSeal matrix sealant (FloSeal group) and 206 patients received alternative agents as topical hemostatic materials (comparison group).

Pseudoaneurysm after patch-free carotid bifurcation endarterectomy: a case report.

The purpose of this report is to present the case of a 59-year-old man affected by multivessel coronary artery disease and sterile pseudoaneurysm of the right carotid bifurcation presenting as a pulsating neck mass 1 month after patch-free carotid endarterectomy. The surgical approach included median sternotomy and incision parallel to the anterior margin of the right sternocleidomastoid muscle. The pseudoaneurysm was excised after control of the brachiocefalic trunk and insertion of a Pruit-Inahara shunt, and the carotid vessels were directly sutured without using any prosthetic or autologous material.

Evaluation of less invasive method for saphenous vein harvest in patients with type II diabetes.

Background: Diabetes mellitus is an established risk factor for leg wound healing complications after great saphenous vein harvest. Leg healing complications occur in 1-25% of coronary artery bypass graft patients, and are often underestimated.

Patients And Methods: The records of 230 patients enrolled in a prospective trial to evaluate a minimally invasive approach compared with conventional longitudinal harvest were reviewed.

Open clip-free radial artery harvesting with the harmonic shears.

Background: The Ultracision Harmonic Scalpel is associated with several advantages in radial artery (RA) harvesting. It allows fewer hemostatic clips to close the collateral branches, less thermal injury of the conduit, and reduced time of harvesting in comparison with the conventional RA harvesting technique with electrocautery and hemostatic clips. We recently started open RA harvesting with the harmonic shears (HSH).
