Computational models based on data from computed tomography show that maximal wall shear stress is associated with the maximal diameter in large aortic aneurysms whereas eccentricity of the bulge is more important in small aneurysms.

In this manuscript the authors present two cases of early thrombosis of biological prosthesis following mitral valve replacement. Both patients were on venous arterial extracorporeal membrane oxygenation (ECMO), which could be the factor responsible for this unusual event. The authors advocate the use of more aggressive anticoagulation on patients on ECMO and prosthetic cardiac valves.

This interesting study evaluates the hemodynamic effect of the residual ASD produced by the transeptal approach for MitraClip implantation. The new left to right shunt could contribute to the reduction in mitral regurgitation following MitraClip implantation

Over 700 lung cancer patients were surveyed at diagnosis and a mean of 54 months later regarding smoking status. 56% of those smoking at the time of diagnosis and stopped smoking 1 year later. Smoking cessation was adversely affected by second hand smoke exposure from housemates, spouses, and peers; these effects were cumulative.

Patients requiring readmission after cardiac surgery were compared to time-matched patients who did not require readmission to evaluate factors associated with this adverse event. Predictors of readmission included COPD, decreased EF, prolonged length of stay, and lower educational level. Failure to see a physician early after discharge increased the risk of readmission by 6-fold.

Pts undergoing aortic root replacement who moderate MR preoperatively were evaluated for outcomes after mitral repair vs no repair. Mitral repair was associated with longer crossclamp times, and postoperative renal failure. Root replacement improved MR without mitral repair, but mitral repair further improved the degree of regurgitation. There was no difference in long-term survival.

Pts surviving esophagectomy longer than 10 years were queried as to QOL. Alimentary comfort rating was 9 out of 10. 33% experienced diarrhea, dumping, or regurgitation. 15% had aspiration requiring hospital care. Mean weight loss was 26 lbs. Median GI QOL score was 2.9 out of 4.

The authors performed VSD closure in children using a 3-port technique and compared the outcomes to patients undergoing open repair. The MIS approach was associated with shorter ICU stay, shorter hospital stay, fewer blood transfusions, and less opioid use.

The CROSS trials randomized pts with esophageal cancer or GEJ cancer to surgery vs induction chemoradiotherapy (CRT) followed by surgery. Prior studies reported a significant improvement in survival and freedom from recurrence associated with induction therapy. In this report, CRT reduced locoregional recurrence from 34% to 14% and reduced peritoneal carcinomatosis from 14% to 4%. Local recurrence within the RT field occurred in only 5% of patients.

The authors performed a population-based study to determine the extent to which mesothelioma occurs absent occupational asbestos exposure. A clear dose-response relationship between degree of exposure and risk of mesothelioma was identified. Occupational exposure to asbestos carried a much higher risk of mesothelioma than did non-occupational exposure, and non-occupational exposure carried a higher risk than did no exposure. Non-occupational exposure to asbestos carried a substantially higher mesothelioma risk in women than it did in men.
