ReviewDoes pulmonary valve replacement post repair of tetralogy of Fallot improve right ventricular function?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether pulmonary valve replacement (PVR) after repair of tetralogy of Fallot improved outcomes including right ventricular (RV) function. Altogether 730 relevant papers were identified using the below mentioned search, 19 papers represented the best evidence to answer the question. ⋯ We conclude that PVR after tetralogy of Fallot repair has been shown to improve RV function and to offer symptomatic benefit. Several retrospective reviews report consistent reductions in RV end diastolic and systolic volumes and improvement in RV stroke volume, with one study also finding improvement in left ventricular stroke volume. PVR in this population appears to result in improved clinical outcome and can be performed with low mortality.

Review Meta AnalysisCirculating matrix metalloproteinase-9 concentrations and abdominal aortic aneurysm presence: a meta-analysis.
To summarize the present evidence for an association between matrix metalloproteinase-9 (MMP-9) and abdominal aortic aneurysm (AAA) presence, we performed a meta-analysis of case-control studies that compared circulating MMP-9 concentrations between patients with AAA and subjects without AAA. MEDLINE database was searched to identify all case-control studies. For each study, data regarding serum or plasma MMP-9 concentrations in both the AAA and control groups were used to generate standardized mean differences (SMDs) and 95% confidence intervals (CIs). ⋯ There was significant study heterogeneity of results (P<0.00001) but no evidence of significant publication bias (P=0.1376). We found that, based on a systematic review and meta-analysis, circulating MMP-9 concentrations are higher in patients with AAA than those in subjects without AAA. Higher circulating MMP-9 concentrations are associated with AAA presence.

Case ReportsSurgical treatment of right atrial myxoma complicated with pulmonary embolism.
Myxomas are the most common type of cardiac benign tumors and most of them are located in the left atrium, followed by the right atrium. Myxomas in the right atrium may rarely embolize to the pulmonary arterial vasculature. Here, we present a case report of a patient with right atrial myxoma and massive embolism to the pulmonary arteries treated surgically with right atrial mass removal and pulmonary embolectomy. ⋯ The left pulmonary artery was completed occluded and the right pulmonary artery was partially obstructed. Surgical tactics included a brief hypothermic circulatory arrest. The patient had an uneventful recovery and was asymptomatic after 6 months of follow-up.

Comprehensive analysis of 4205 patients with chest trauma: a 10-year experience.
Thoracic trauma is one of the leading causes of morbidity and mortality in developing countries. In this retrospective study, we present our 10-year experience in the management and clinical outcome of 4205 cases with chest trauma associated with blunt and penetrating injuries in a level I trauma hospital in Turkey. In 66% of the cases, blunt injury mostly related to traffic accidents was the cause of chest trauma. ⋯ Mortality and injury severity score (ISS) increased in patients having early surgery (P=0.001). Although most patients could be managed with conservative approaches, early thoracotomy was required in some cases. We believe that urgent hospital admission, early diagnosis, and multidisciplinary approach are very important to improve outcome.
