Polytetrafluoroethylene Felt Inlay Neomedia and Tissue Glue Do Not Prevent Reoperation in Type A Aortic Dissection.

Type A aortic dissection repair using Polytetrafluorethylene (PTFE) felt inlay and tissue glue has been proposed as a treatment modality. It remains unclear, if this method performs superiorly to tissue glue only. Between January 2011 and December 2015, 139 patients underwent surgical repair for type A aortic dissection, and 48 patients were excluded ( = 29 after receiving a composite graft, = 18 in which no tissue glue was used, and = 1 due to missing data).

In-Hospital Graft Occlusion in Post-Coronary Artery Bypass Grafting Patients in the Early Postoperative Period: A Systematic Review and Meta-Analysis.

: The objectives of this paper are to evaluate the incidence of early graft occlusion during hospital stays following coronary bypass surgery (CABG) and to assess the factors influencing the odds of in-hospital early graft occlusion. : Reports evaluating the early in-hospital occlusion of coronary bypass grafts were identified through PubMed, Embase, and Cochrane databases. The primary endpoint was to determine the incidence of early graft occlusion following CABG before discharge and to identify and quantify the impact of demographic, clinical, and procedural risk factors on the occurrence of early graft occlusion.

Background: We aimed to analyse the performance of minimal invasive extracorporeal circulation (MiECC) concomitantly with Microplegia, in patients with recent myocardial infarction (MI) undergoing urgent coronary artery bypass grafting (CABG) surgery. Methods: We included patients with a recent MI (≤7 days) undergoing isolated CABG surgery using MiECC. The primary endpoint was a major cardiovascular or cerebrovascular event (MACCE).

Management of left subclavian artery in type B aortic dissection treated with thoracic endovascular aorta repair.

Objective: Thoracic endovascular aortic repair (TEVAR) has been the favored approach for the treatment of type B aortic dissection (TBAD). To obtain an adequate proximal landing zone, coverage of the left subclavian artery (LSA) will often be necessary. The occurrence of possible neurologic complications has continued to be debated.

Rotational Thromboelastometry Values After On-Pump Cardiac Surgery - A Retrospective Cohort Study.

Background: Viscoelastic coagulation monitoring is recommended for coagulation management after cardiac surgery, but optimum target values are poorly defined.

Aims: To determine "to-be-expected" values in rotational thromboelastometry (ROTEM) after heparin reversal, to correlate ROTEM parameters with fibrinogen levels and platelet count, and to estimate the effect of hemoglobin levels on these measurements.

Methods: We retrospectively analyzed 571 consecutive adult patients undergoing cardiac surgery with cardiopulmonary bypass from 12/2018 to 08/2020.

Non-invasive evaluation of new-onset atrial fibrillation after cardiac surgery: a protocol for the BigMap study.

Aims: New-onset atrial fibrillation (NOAF) is the most common complication after cardiac surgery, occurring in 25-50% of patients. It is associated with post-operative stroke, increased mortality, prolonged hospital length of stay, and higher treatment costs. Previous small observational studies have identified the left atrium as a source of the electrical rotors and foci maintaining NOAF, but confirmation by a large prospective clinical study is still missing.

Aortic Root Thrombus Directly After Left Ventricular Assist Device Implantation.

A 70-year-old female heart failure patient could not be weaned from temporary left ventricular mechanical support with Impella CP (Abiomed Inc, Danvers, MA) after myocardial infarction; therefore, she underwent left ventricular assist device implantation (HeartMate 3; Abbott, Chicago, IL). After uneventful surgery, the patient had an early postoperative thrombus in the aortic root, and surgical thrombectomy on extracorporeal circulation was performed on the seventh postoperative day. The patient recovered well and presented in good condition with no neurologic symptoms at the 6-month follow-up visit.

Outcome of right ventricular assist device implantation following left ventricular assist device implantation: Systematic review and meta-analysis.

Objectives: The main aim was a systematic evaluation of the current evidence on outcomes for patients undergoing right ventricular assist device (RVAD) implantation following left ventricular assist device (LVAD) implantation.

Endovascular treatment of the dissected proximal aortic arch: a systematic review.

Objectives: Surgical repair of aortic dissection involving the proximal aortic arch is associated with higher morbidity and mortality, in particular when elderly high-risk patients are concerned. Endovascular treatments for this disease are under evaluation and some reports exist. We investigated the current use of catheter-based treatments for the dissected proximal aortic arch repair.

Design optimization of bidirectional arterial perfusion cannula.

Objectives: Determine if shortening the covered section of a self-expanding bidirectional arterial cannula, can enhance retrograde flow and thus reduce the risk of lower limb ischemia.

Methods: Outlet pressure vs flow rate was determined for three cannulas types: a 15F self-expanding bidirectional cannula having a covered section of 90 mm, the same cannula but with a shorter covered section of 60 mm, and a Biomedicus cannula as control. The performances of all the cannulas were compared using a computerized flow-bench with calibrated sensors and a centrifugal pump.
