Combined elective percutaneous coronary intervention and transapical transcatheter aortic valve implantation.
There is no established strategy of how and when to treat coronary artery disease (CAD) in patients referred for transcatheter aortic valve implantation (TAVI). Simultaneous, single-stage treatment of both pathologies is a possible solution. We report our initial results of simultaneously performed transapical TAVI and elective percutaneous coronary interventions (PCI) in high-risk patients with severe aortic valve stenosis. ⋯ Survival at 12, 24 and 36 months of the PCI and TAVI group 87.1 ± 5.5, 69.7 ± 10.3 and 69.7 ± 10.3%, respectively. The results showed that the single-stage approach with combined elective PCI and TAVI is feasible and safe. It has become our primary choice for treatment of high-risk patients with severe aortic valve stenosis and CAD.

ReviewUse of gentamicin-collagen sponges in closure of sternal wounds in cardiothoracic surgery to reduce wound infections.
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: Are antibiotic implants like gentamicin-collagen implants useful in preventing sternal wound infections (SWIs)? Altogether, more than 484 papers were found using the reported search; of these, 7 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. ⋯ Coagulase-negative staphylococci were predominantly isolated from infected wounds in all the trials except the one from USA, where infections were polymicrobial. Gentamicin resistance among common pathogens causing SWIs can vary from 15 to 80%. Gentamicin-collagen is unlikely to reduce SWIs in high-risk patients and polymicrobial infections.

ReviewIs a fully heparin-bonded cardiopulmonary bypass circuit superior to a standard cardiopulmonary bypass circuit?
A best-evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was 'Is a fully heparin bonded cardiopulmonary bypass circuit superior to a standard cardiopulmonary bypass circuit?' Altogether more than 792 papers were found using the reported search, of which 13 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 (Table 1). ⋯ Two studies found reduced levels of polymorphonuclear elastase (P < 0.018-0.001) and two trials concluded that the use of heparin-coated circuits in combination with low-dose systemic heparin (activated clotting time >250) resulted in the greatest clinical benefit and improvement in inflammation. One study documented significant platelet preservation with the use of third-generation heparin-polymer-bonded circuits (P ≤ 0.05). We conclude that despite heparin-bonded and newer third-generation heparin-polymer-bonded cardiopulmonary bypass circuits having a greater cost per person, their improved clinical outcomes and biocompatibility in patients undergoing cardiac surgery make them a preferable option to standard non-heparin-bonded circuits.

Multicenter StudyPlatelet reduction after stentless pericardial aortic valve replacement.
The aim of the study was to investigate the multi-factorial phenomenon of possible postoperative thrombocytopenia after aortic valve replacement (AVR) with the freedom SOLO (FS) bioprosthesis. A total of 254 patients underwent AVR with FS bioprosthesis in two cardiac surgery institutes. Platelet counts were measured preoperatively, immediately postoperatively and daily until the 11th day postoperatively. ⋯ Compared with patients with no preoperative thrombocytopenia, patients with preoperative thrombocytopenia had an 8.69 increased odds of being in the group with postoperative platelet count <150 10(3)/mm(3). No major haemorrhagic or thromboembolic event was reported during hospitalization. This study shows that thrombocytopenia after the FS bioprosthesis replacement is a transient postoperative phenomenon, largely resolved within a few days after surgery, with no clinical consequences and haemodynamic dysfunction.

Surgical results and long-term follow-up of T(4)-non-small cell lung cancer invading the left atrium or the intrapericardial base of the pulmonary veins.
Patients with locally advanced non-small cell lung cancer infiltrating the left atrium (LA) or the intrapericardial base of the pulmonary veins (PVs) are generally not considered good candidates for surgery because of the poor long-term survival. In the last 10 years, 31 consecutive patients with non-small cell lung cancer directly invading the LA or the intrapericardial base of the PVs underwent surgery. Pneumonectomy was the operation performed most frequently. ⋯ In these patients, surgery could be performed with an acceptable operative mortality and morbidity. Surgery should be considered whenever a complete resection is technically possible. A careful preoperative evaluation is mandatory to select good candidates for surgery.
