Review Comparative StudyIn patients with concomitant aortic and mitral valve disease is aortic valve replacement with mitral valve repair superior to double valve replacement?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: in patients with concomitant aortic and mitral valve disease is aortic valve replacement with mitral valve plasty (MVP) superior to double valve replacement (DVR) in terms of improved long-term survival? Altogether 156 papers were found using the reported search, of which seven represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. ⋯ All data presented derive from level 2b evidence. Critical appraisal of these studies is constricted by the large heterogeneity of the patients, diversity in treatment protocols and inherent selection bias. We conclude that currently the available evidence is insufficient to prove that AVR with MVP is superior to DVR in patients with double valve disease.

How good patient blood management leads to excellent outcomes in Jehovah's witness patients undergoing cardiac surgery.
The refusal of blood products makes open-heart surgery in Jehovah's witnesses (JW) an ethical challenge. We demonstrate how patient blood management strategies lead to excellent surgical outcomes. ⋯ Patient blood management leads to excellent short- and long-term outcomes in JW. Combined efforts in regard to preoperative hematological parameter optimization, effective volume management and meticulous surgical techniques make this possible but raise the cautionary note why this is only possible in JW patients.

Comparative StudyRemoval of aprotinin from low-dose aprotinin/tranexamic acid antifibrinolytic therapy increases transfusion requirements in cardiothoracic surgery.
This retrospective study investigated whether withdrawal of aprotinin from combined low-dose aprotinin/tranexamic acid (TXA) antifibrinolytic therapy altered postoperative blood loss and transfusion requirements in patients undergoing cardiothoracic surgery employing cardiopulmonary bypass (CPB). The study included data from patients receiving a combination of low-dose aprotinin (2×10(6) KIU in CPB prime; n=615) and 2000 mg TXA or patients receiving TXA only (n=587). In both groups, TXA was given after protamine administration. ⋯ Postoperative blood loss (0.80±0.69 vs. 0.66±0.52 l; P=0.001) and transfusion of fresh frozen plasma (0.6±0.7 vs. 0.4±0.6 U; P<0.001), packed cells (3.9±5.5 vs. 2.7±3.3 U; P<0.001) and platelets (0.7±0.6 vs. 0.5±0.6 U; P<0.001) was higher in the TXA group than in patients receiving combined therapy, respectively. There were more reoperations for bleeding in the TXA group (53 vs. 34, respectively; P=0.03) with similar mortality and deterioration in glomerular filtration rate. In conclusion, withdrawal of aprotinin from combined antifibrinolytic therapy is associated with increased blood loss, transfusion requirements and reoperations.

Case ReportsDirect right atrial insertion of a Hickman catheter in an 11-year-old girl.
Central venous lines are of particular importance in seriously ill children that require parenteral nutrition, chemotherapy, or other medications. The jugular or subclavian veins are ordinarily used for primary access. Alternatives include the femoral veins, the intercostal veins, and transhepatic approaches. ⋯ The following report presents the case of an 11-year-old girl with short-bowel syndrome and a desperate need for parenteral nutrition. Over the course of her treatment, she developed chronic thrombosis of the jugular, subclavian, and femoral veins, as well as thrombosis of the inferior vena cava. As an alternative route for central venous access, we describe a successful direct placement of a tunnelled catheter into the right atrium via a right anterolateral thoracotomy.
