Transcatheter aortic valve replacement (TAVR) has, without a doubt, brought an unprecedented excitement to the field of interventional cardiology. The avoidance of a sternotomy by transfemoral or transapical aortic-valve implantation appears to come at the price of some serious complications, including an increased risk of embolic stroke and paravalvular leakage. The technical challenges of the procedure and the complex nature of the high-risk patient cohort make the learning curve for this procedure a steep one, with the potential for unexpected complications always looming.

Chest drainage following cardiac surgery is used to avoid complications related to the accumulation of blood and serous fluid in the chest. We aimed to determine the incidence of chest tube clogging and the role of bedside assessment in identifying the potential for failure to drain.
CONCLUSIONS:
The chest tubes can become clogged at any time after their placement. The status of urgency, reoperations and use of blood products can be contributing factors increasing the incidence of chest tube clogging. Clinicians likely underestimate the prevalence of this failure to drain, as most clogging occurs in the internal portion of the tube.

The use of glues to repair disrupted tissue during acute type-A aortic dissection (TAD) surgery may be discontinuous, and cause embolization and cell necrosis. We report a method of fibrin sealant patch (FSP) to reinforce dissected aortic tissue with a collagen double layer coated with fibrinogen/thrombin on either side

the Prospective Randomized On–X Anticoagulation Clinical Trial (PROACT) tests the safety of less aggressive anticoagulation than is recommended by ACC/AHA guidelines after implantation of an approved bileaflet mechanical valve. INR may be safely maintained between 1.5–2.0 after AVR with this approved bileaflet mechanical prosthesis. With low–dose aspirin, this resulted in significantly lower risk of bleeding, without significant increase in TE.

The accuracy of the diagnosis in patients undergoing congenital heart surgery in a large administrative database was examined in over 14,000 patients aged 0 to 5. Patients admitted on day 1 of life and those undergoing ECMO had a much higher chance of being assigned non-cardiac diagnoses. Pts so misclassified had a substantially higher risk of mortality. This systematic misclassification may lead to inaccurate determination of case volumes and outcomes.

Because the optimal management of CAD is unclear for many patients, the authors developed a decision support model for CABG and PCI with bare metal or drug eluting stents. Overall survival rates were similar for the different interventions. For PCI with drug eluting stents, optimal outcomes were observed for pts undergoing emergency revascularization for acute MI. Optimal outcomes for CABG were observed in pts with multivessel disease and with many comorbidities.

The authors report outcomes for recipients of heart transplants performed more than 20 years prior. Overall 20 year survival was 56%. Causes of mortality were similarly distributed among rejection, malignancy, infection, and allograft vasculopathy. Only 2 patients underwent retransplantation.
