New predictor of aortic enlargement in uncomplicated type B aortic dissection based on elliptic Fourier analysis.
This study aimed to re-examine the conventional predictive factors for dissected aortic enlargement, such as the aortic and false lumen diameter and to consider whether the morphological elements of the dissected aorta could be predictors by quantifying the 'shape' of the true lumen based on elliptic Fourier analysis. ⋯ The analysed and calculated morphological data of the shape of the true lumen can be more effective predictive factors of aortic enlargement of type B dissection than the conventional factors.

The first publication of Loeys-Dietz syndrome (LDS) described aortic rupture at young ages. Experience with new LDS types showed that the clinical course varies, and thresholds for prophylactic surgery are discussed. As this is an uncommon disease, experience needs to be shared. ⋯ Clinical course seems to be more aggressive in LDS2, with index operation at a younger age, and higher risk of needing several operations. Vascular disease distal to the arch is not uncommon. LDS3 seems to be associated with mitral valve disease. Prophylactic aortic root surgery is safe and durable.

Review Meta AnalysisStopping versus continuing acetylsalicylic acid before coronary artery bypass surgery: A systematic review and meta-analysis of 14 randomized controlled trials with 4499 patients.
This study aimed to evaluate the efficacy and safety of continuing versus stopping aspirin [acetylsalicylic acid (ASA)] preoperatively in patients undergoing coronary artery bypass graft surgery. MEDLINE, EMBASE, CENTRAL/Cochrane Controlled Trials Register (CCTR), ClinicalTrials.gov, Scientific Electronic Library Online (SciELO), Literatura Latino Americana em Ciências da Saúde (LILACS), Google Scholar and reference lists of relevant articles were searched for randomized controlled trials that reported efficacy outcomes of myocardial infarction and mortality, and safety outcomes of blood loss, packed red blood cell transfusion and surgical re-exploration were compared between groups. Fourteen studies fulfilled our eligibility criteria and included a total of 4499 patients (2329 for 'continuing ASA' and 2170 for 'stopping ASA'). ⋯ Preoperative ASA increased postoperative chest tube drainage (mean difference 143 ml, 95% CI 39-248 ml; P = 0.007) and packed red blood cell transfusion (mean difference 142 ml, 95% CI 55-228; P = 0.001) but did not increase the risk of surgical re-exploration (risk ratio 1.316, 95% CI 0.910-1.905; P = 0.145). This meta-analysis found no statistically significant difference regarding the risk of operative mortality and myocardial infarction between the 'continuing ASA' and 'stopping ASA' strategies. On the other hand, the mean volume of blood loss and packed red blood cell transfusion was higher in the 'continuing ASA' group, but this finding did not translate into higher risk of reoperation for bleeding.

Observational StudyPostoperative bleeding in coronary artery bypass patients on double antiplatelet therapy: predictive value of preoperative aggregometry.
We tested the possible value of routine aggregometry testing for bleeding prediction following coronary artery bypass grafting in patients who received preoperative double antiplatelet therapy. ⋯ Aggregometry can help in predicting postoperative bleeding in double antiplatelet therapy patients undergoing coronary artery bypass grafting.

Beating heart mitral valve repair with neochordae implantation: real-time monitoring of haemodynamic recovery.
Transapical off-pump mitral valve repair with neochord implantation has been approved for patients presenting with severe mitral regurgitation due to leaflet prolapse or flail. The procedure is performed under real-time 2D and 3D transoesophageal echocardiography for both implantation and neochordae tension adjustment allowing real-time monitoring of haemodynamic recovery.
