Padova and Bologna groups present an interesting cohort of patients treated with cadaveric cryopreserved sternocondral allograft for reconstruction of the anterior chest wall.

Coronary and/or CT angiograms were performed on 585 of 762 (94%) patients at varying intervals after CABG using the PAS-Port System proximal anastomotic device.  The authors retrospectively evaluated the SVG patency at a mean follow-up interval (between CABG and the diagnostic procedures) was 319 ± 624 days.  The patency rates of the SVG grafts performed with the device were 90% and 81% at 1 and 5 years, respectively, which compare very favorably with established SVG patency rates.

These authors from Spain retrospectively analyzed a group of 805 patients undergoing isolated heart valve surgery in order to correlate levels of high-sensitivity troponin T (hs-cTnT) and CK-MB with whether a patient experienced a postoperative MI, as diagnosed by EKG and/or TTE.   In all, 88 patients (10.9%) met the criteria for MI.  In comparing the non-MI to the MI patients, the authors found, by analyzing the Receiver Operating Characteristics (ROC), the following peak cut-off levels to distinguish whether a patient had a postop MI or not: hs-cTnT:  >1057 pg/mL @ 16 hours CK-MB:  >55 mg/dl @ 8 hours.

The authors reviewed the retrospective INTERMACS database to assess whether outcomes after continuous-flow (CF) LVAD implantation varied with patient BSA.  A total of over 10,000 CF LVAD patients were included.  Of these, 231 (2%) had a BSA < 1.5 m².   Outcomes:  Survival was similar.  Postoepratively, smaller patients had a higher incidence of bleeding and driveline infection, but a lower incidence of RV failure and renal dysfunction.

The authors report on an echocardiographic sub-study of the NOTION trial, a prospective randomized study which compared outcomes between 120 patients undergoing TAVI and 112 patients undergoing aortic valve replacement (AVR).  Although at 12 months of follow up, aortic valve area had increased significantly more in patients undergoing TAVI, left ventricular mass regression was more pronounced in those patients undergoing AVR. Also, whereas end diastolic volume (EDV) decreased in the AVR group, EDV increased in the TAVI group. Patients undergoing TAVI had more paravalvular leaks and need for pacemaker implantation. This could explain the differences in left ventricular mass and EDV in favour of AVR.

Dr Rakesh Suri is the Guest Editor in this special issue of the Annals of Cardiothoracic Surgery exploring the emerging role of robotic instrumentation in cardiac surgery. With leading authors from the most experienced international institutions, we examine the current evidence, limitations, and future directions of this minimally invasive surgical technique. Contributors include Randolph Chitwood, Matteo Pettinari, Kent Rehfeldt, Harold Burkhart, Didier Loulmet and many more.

A review of particular interest for procurement (retrieval) of hearts after brain injury, especially subarachnoid bleeding, the commonest cause of death in DBD in our practice.  The authors discuss, amongst other things, the early stress micro-infarcts that may limit the performance of the donated heart, especally in female donors with sub arachnoid bleeding, and explain some common electrocardiographic changes ( especially the cerebral T ) that may puzzle the retrieval (procurement) team.  The essential catecholaminergic pathway for these changes is discussed in detail.

Check out this very interesting website that has been set up to help patients who are looking for information on thoracic surgery prior to an operation.  It is really friendly and comprehensive and is a great resource for all patients who may want to find out more about their  operation.

These guidelines are intended to be a detailed, evidence-based resource for surgeons who practice SSRF. The goal of the author group was to both update and expand upon previous guidelines by focusing on SSRF specifically and incorporating the rapid increase in both literature and technology observed over the last five years.

A retrospective, matched cohort study to determine attributable hospital costs associated with surgical site infection after pediatric cardiothoracic surgery was performed. Of the 981 surgical cases within the study period, 12 with surgical site infection were identified. Compared to individually matched controls, children with surgical site infection had an associated increase in hospital costs of $136,950/case and hospital length of stay of 9.5 days/case. These data stress the importance of infection surveillance and prevention.
