ABSTRACT
BACKGROUND: Surgical site complications represent major concerns in many surgical specialties and lead to an increased length of hospital stay and the need for additional treatments and care. This investigation aimed to report survey data from the introduction of the PICO negative pressure wound therapy system (Smith & Nephew, Hull, United Kingdom) in a single hospital in France regarding cardiac surgical procedures through standard median sternotomy. METHODS: The patients in this study were at high risk of developing surgical site infections. PICO was used immediately postoperatively on the closed incision sites in all patients undergoing cardiac surgical procedures. Data were compared with a retrospective cohort of patients in whom PICO had not been used postoperatively. In total, 233 anonymized patient records were reviewed, 142 of which used the PICO device and 91 of which did not. RESULTS: PICO was shown to provide both clinical and economic benefits over standard care across a range of different cardiac surgical patients. The rates of complications, including deep surgical wound infections and mediastinitis, were reduced. CONCLUSIONS: As noted, PICO had advantages over standard care in these patients, and complication rates decreased. This study demonstrated cost savings and an increase in available surgical and hospital capacity related to PICO use.

OBJECTIVES: The Ross procedure has received increasing interest as an attractive alternative to a prosthetic aortic valve. Given its presumably greater resistance to infection, the pulmonary autograft is theoretically preferable for active endocarditis. The objective of this retrospective study was to present our experience in aortic valve endocarditis treated using the Ross procedure. METHODS: Between May 1997 and February 2011, the Ross procedure was performed on 142 patients in our institution. Twenty-eight patients had aortic valve endocarditis at the time of operation. Fourteen patients had urgent or emergency procedures, and 13 had active disease at the time of surgery. Twelve patients were alcoholics and/or drug addicts. Eight patients had an abscess of the aortic annulus. Clinical follow-up was complete. RESULTS: Hospital mortality was 10.7%. Overall patient survival (± standard deviation) was 47 ± 13% at 10 years with no cardiac-related death during the mean follow-up of 6.4 ± 4.2 years. There were 3 cases of recurrent endocarditis including anterior mitral leaflets endocarditis and right-sided endocarditis to another germ in a drug addict. Four patients required further surgery, 2 on the pulmonary autograft; 18 of the 19 survivors were in New York Heart Association class I. At the final investigation, all patients had no or grade I autograft regurgitation. The mean pressure gradient across the homograft was 9 ± 7.5, 11 ± 9.5 and 15 ± 9.5 mmHg, respectively, for patients between 0-3, 4-9 and >9 years. CONCLUSIONS: Endocarditis can be treated with good results using the Ross procedure, with a very low rate of recurrence of endocarditis.

The patient, who had undergone a complete cure of a tetralogy of Fallot 25 years previously, was discovered to have an ascending aorta aneurysm on echography. Bentall's procedure was carried-out, using a modified indirect coronary artery transplantation based on the Cabrol technique. As reported in the literature complications are mainly right sided and less frequently occur on the left side in this disease. Including the hypothesis of the overload volume which may provoke aortic root dilation, there is also an intrinsic pathology of the media which could often be related to embryogenesis abnormalities, i.e., abnormal migration of cardiac neural crest cells which may explain this condition.

The most common aortic valve congenital abnormality is observed in bicuspid aortic valve. Only a few cases of aortic valve quadricuspidy have been reported in the literature. We report a new case of endocarditis complicating a congenital quadricuspid aortic valve.

BACKGROUND: Mesenteric ischemia and acidosis leading to intestinal ischemia has been observed during cardiopulmonary bypass (CPB) despite normal flow in the mesenteric vessels. The aim of this study was to assess mesenteric endothelium-dependent reactivity and vasoconstrictor responses of small mesenteric arteries in a rat model of CPB without aortic cross-clamping. METHODS: After femoral cannulation a partial 90 minutes CPB was performed with hemodynamics and blood gas parameters monitoring. Blood samples and segments of small mesenteric arteries were obtained in rats sacrificed 2.5 hours (CPBH2.5) or 6 hours (CPBH6) after femoral cannulation. Sham surgery (sham H2.5, sham H6) was performed with femoral cannulation only. Segments of small mesenteric arteries were placed in a myograph in order to assess the contractile response to phenylephrine (with or without NO synthase inhibitor) or the endothelium-dependent relaxation to acetylcholine. Systemic inflammation was evaluated by measuring plasma concentrations of TNFalpha. Pulmonary and intestinal infiltration of activated leukocytes was assessed by immunohistochemistry. RESULTS: CPB induced increased contractile response to phenylephrine which persisted after blockade of NO synthesis as well as transient impairment of endothelium-dependent relaxations. CPB also led to early and marked release of TNFalpha. CONCLUSIONS: CPB was responsible for mesenteric endothelial dysfunction and direct increase in the contractile response to alpha1-adrenergic agonist with increased systemic inflammatory response. This phenomenon might contribute to an increase in the risk of mesenteric ischemic events during cardiac surgery especially when vasopressor agents are used.
