Vida and colleagues retrospectively reviewed 111 left-sided reoperations after an arterial switch operation (ASO) across 17 ECHSA centers between 1975 and 2010. The authors found a low reoperation frequency of 1.4% after ASO. Initial diagnosis of D-transposition of the great arteries (D-TGA) was more common among patients who required reoperation than was diagnosis of double-outlet right ventricle TGA-type, however a greater percentage of the latter group encountered postoperative complications (5 of 12, versus 16 of 99). The majority of survivors were asymptomatic at last follow-up, with only 13% in New York Heart Association class II and only 3% in class III.

We urgently need more answers for the patients affected by mesothelioma, a devastating diasese whose prognosis is 6-9 months from the diagnosis. We are now living the era of plateau of the epidemiology due to industrial use of amiantus of the last century. Furthermore, there are other etiology than asbestos in endemic areas, like for example the natural exposure to fluoro-edenite of certain regions of Japan and Sicily. We do need more informatinos to direct the difficult management of all these individuals and there are many ongoing studies where surgery is considered a valid option. This trial will compare the outcome of 2 groups: the first group will have a debulking surgery and hyperthermic intraoperative intrathoracic chemotherapy (HITHOC) with cisplatinum while the second group will receive talc pleurodesis alone. The primary outcomes measured will be length of hospital stay, quality of life, and long-term survival.
This single institution observational study compares clinical outcomes and resource utilization associated with two surgical approaches for single-stage repair of coarctation of the aorta and ventricular septal defect. Authors found that single-stage two-incision repair of both defects in appropriately selected patients may be associated with higher value of care compared to single-stage one incision repair.
The authors queried the UNOS heart transplantation database to determine if LVAD device-related complications (DRCs) were associated with worse postoperative graft survival. The 5 categories of DRCs were as follows: device thrombosis, infection, device malfunction, life-threatening arrhythmias, and others.
Results: None of the 5 categories of DRCs was associated with worse graft survival on multivariate analysis.
In this study the authors randomized 142 patients within two separate treatment arms: (1) Patients undergoing on-pump CABG were randomized to either a single- vs. double-clamp technique for proximals; (2) patients undergiong OPCAB were randomized to either a Heartstring device or single clamp for proximals. For all 4 treatment groups, the number of embolic HITS was assessed with transcranial doppler of the middle cerebral artery.
(1) On-pump CABG: The mean number of HITS in the single-clamp group was 10.0, while that for the double-clamp group was 16.0 (p=.10). (Although the difference was not significant, the treatment groups were rather small.)
(2) OPCAB: The mean number of HITS in the Heartstring group was 30.0, whereas that for the partial clamp group was 7.0 (p<.0001). Thus, the Heartstring group had more than 4 times the embolic load by TCD.
Notably, neurocognitive outcomes were not different among the groups.
Three more UK surgical centers will introduce heart transplants from non-heart beating donors. In the UK, this procedure is currently only performed at three hospitals, where it benefits patients such as this sports enthusiast.

This study details the short- and long-term outcomes for more than 3,000 patients who underwent septal myectomy for hypertrophic cardiomyopathy at the Mayo Clinic in Rochester, United States, from 1993 to 2016. In over 90% of severely symptomatic patients, relief of left ventricular outflow tract obstruction resulted in clinical improvement by at least two functional classes and reduced or eliminated symptoms of dyspnea, angina, and/or syncope.
The authors also outline outcomes for the transapical approach for basal obstruction with systolic anterior motion in 115 patients between 1993 and 2012, with all patients demonstrating postoperative gradient relief without the complication of an apical aneurysm or ventricular septal defect. These results emphasize that excellent outcomes can result from myectomy performed in experienced centers, with early mortality for isolated septal myectomy being less than 1%.
