Summary
Aims This study investigated the early and mid–term results following valve replacement with the new Shelhigh? stentless bioprosthesis made entirely of biological material in patients with active infective endocarditis (AIE).
Material and methods Between 02/2000 and 12/2004, 164 patients (n = 122 men, mean age 59, 18–85 years) received implantation of an AIE Shelhigh? stentless bioprosthesis in the aortic, mitral, tricuspid or pulmonary position. A total of 119 patients (72.6%) had native
AIE and 45 (27.4%) prosthetic AIE. A large proportion of the patients reached the operating room in a condition of cardiac
decompensation: 37 (22.6%) patients were intubated, 40 (24.4%) had protracted septic shock and 41 (25.0%) required intensive
catecholamine treatment. Surgery was regarded as urgent in 94 patients (57.4%) and was performed as an emergency procedure
in 70 (42.6%). The mean follow–up time is 1.5 ± 0.11 years (range, 5 months to 5.2 years). Echocardiographic follow–up examinations
were performed early postoperatively and after 12 months.
Results In terms of the operative indication, we found a highly significant difference in the survival rate between patients who were
operated on urgently vs in an emergency. In patients who died within 30 days, the main cause of death was septic multiorgan
failure (67.6%). Only three patients required reoperation due to reinfection of the Shelhigh? bioprostheses; this represents a reinfection rate of 1.8% in relation to the whole cohort. The postoperative echocardiographic
examinations showed the Shelhigh? valves to have very good hemodynamics without relevant pressure gradients.
Conclusion Our experience in the use of Shelhigh? bioprostheses in patients with native and prosthetic endocarditis show the early and mid–term results, in particular the
low reinfection rate and the good hemodynamics, to be comparable with the results achieved using homografts. Since these prostheses
are readily available and their implantation straightforward, they are increasingly being used in patients with endocarditis.
These promising results need to verified in the long term.

OBJECTIVE: Due to the shortage of donor hearts, the criteria for organ acceptability have been considerably extended and donor grafts with coronary atherosclerosis are among those offered. This study evaluated whether and to what degree pre-existing coronary atherosclerosis may be acceptable. METHODS: A total of 1253 consecutive HTx recipients were investigated retrospectively for donor-transmitted coronary atherosclerosis (DCAS). Donor-transmitted coronary atherosclerosis was defined as focal atherosclerosis with stenosis of at least 50%. Inclusion criteria were absence of pre-HTx angiogram but performance of angiogram or autopsy within 6 months after heart transplantation. Kaplan-Meier analysis and log-rank test were used. RESULTS: Eighty-five out of 1253 (6.8%) cases were excluded, since coronary evaluation was not performed within 6 months (n=45) or hearts had undergone pre-transplant angiography (n=40). In 1086 patients no donor-transmitted coronary atherosclerosis was found (NDCAS group) and in 82 patients (7%) donor-transmitted coronary atherosclerosis was diagnosed by angiography (n=49) or autopsy (n=33). Single-vessel donor-transmitted coronary atherosclerosis was found in 53/82 patients (DCAS1 group) and double- or triple-vessel donor-transmitted coronary atherosclerosis in 26/82 patients (DCAS2/3 group). Three of the 82 patients with donor-transmitted coronary atherosclerosis were excluded since the autopsy report was unclear regarding degree of atherosclerosis. Early after heart transplantation the 30-day mortality in the NDCAS and DCAS1 groups was 12.2% versus 13.2% whereas in the DCAS2/3 group it was 61.5%. Beyond the first year the annual decrease with and without donor-transmitted coronary atherosclerosis (single-vessel disease) is comparable. CONCLUSIONS: Donor screening without coronary angiogram overlooks significant atherosclerotic lesions in a considerable number of cases (7.0%). Therefore, angiographic donor screening should be performed. Donor grafts with single-vessel coronary atherosclerosis may be accepted as marginal hearts; however, in our opinion, revascularisation (CABG, PTCA) should be considered. Grafts with two- or even three-vessel coronary atherosclerosis seem to have a serious risk for early graft failure. Beyond the first year the outcome of healthy grafts and grafts with donor-transmitted coronary atherosclerosis seems to be comparable. 相似文献

We report a patient with bicuspid aortic valve and dilatation of the ascending aorta who had previous aortic valve replacement and reduction aortoplasty with wrapping. After 4 years, reoperation because of coronary artery disease and paravalvular leakage revealed an erosion of the aortic wall due to dislocation of the wrap. This complication confirms the need for secure anchoring and good fitting of the Dacron wrap to avoid alterations of the underlying aortic wall. 相似文献

Background Morbidly obese patients have a high prevalence of known and unknown cardiopulmonary diseases. The aim of this study was to
assess the value of cardiopulmonary tests routinely performed before bariatric surgery.
Methods The population studied included 67 women and 10 men, aged 39 ± 10 years, with a body mass index of 43 ± 4 kg/m2. All patients, candidates for laparoscopic gastric banding, underwent after clinical evaluation: resting electrocardiography
(ECG), Doppler-echocardiography, exercise stress testing, Epworth Sleepness Scale, and polysomnography, spirometry, blood
gases, and chest x-ray.
Results The ECG demonstrated conduction or ST-T wave abnormalities in 48 patients (62%). Prolongation of the QT interval >10% was
found in 13 patients (17%). Stress tests were negative in 56 patients (73%) and were not interpretable in the remaining 21
patients (27%). Doppler-echocardiography showed hypertrophy of the left ventricular posterior wall in 47 patients (61%) without
any consequences on perioperative management. Polysomnography showed an obstructive sleep apnea–hypopnea syndrome (OSAHS)
in 31 patients (40%), leading to preoperative continuous positive airway pressure (CPAP) treatment in 17 patients (22%). Nevertheless,
the Epworth Sleepness Scale was pathological in only 17 patients (22%). Ten patients (13%) presented minor chest x-ray alterations.
Spirometry demonstrated an obstructive respiratory syndrome in 13 patients (17%) and a restrictive syndrome in five patients
(6%). Hypoxemia <80 mmHg was observed in 21 patients (27%) and hypercapnia >45 mmHg in six patients (8%), without any consequences
on the management of the perioperative period.
Conclusion We recommend the preoperative assessment by clinical evaluation, ECG, and polysomnography. For patients with cardiac or pulmonary
histories and/or ECG abnormalities, we recommend echocardiography, spirometry, and blood gases. 相似文献

Introduction
The purpose of this study was to assess the relation between glycaemic control and the severity of sepsis in a cohort of patients treated with intensive insulin therapy (IIT).Methods
In a prospective, observational study, all patients in the intensive care unit (ICU) (n = 191) with sepsis, severe sepsis or septic shock were treated with IIT (target blood glucose (BG) level 80 to 140 mg/dl instead of strict normoglycaemia). BG values were analysed by calculating mean values, rate of BG values within different ranges, rate of patients experiencing BG values within different levels and standard deviation (SD) of BG values as an index of glycaemic variability.Results
The number of patients with hypoglycaemia and hyperglycaemia was highly dependent on the severity of sepsis (critical hypoglycaemia ≤ 40 mg/dl: sepsis: 2.1%, severe sepsis: 6.0%, septic shock: 11.5%, p = 0.1497; hyperglycaemia: >140 mg/dl: sepsis: 76.6%, severe sepsis: 88.0%, septic shock: 100%, p = 0.0006; >179 mg/dl: sepsis: 55.3%, severe sepsis: 73.5%, septic shock: 88.5%, p = 0.0005; >240 mg/dl: sepsis: 17.0%, severe sepsis: 48.2%, septic shock: 45.9%, p = 0.0011). Multivariate analyses showed a significant association of SD levels with critical hypoglycaemia especially for patients in septic shock (p = 0.0197). In addition, SD levels above 20 mg/dl were associated with a significantly higher mortality rate relative to those with SD levels below 20 mg/dl (24% versus 2.5%, p = 0.0195).Conclusions
Patients with severe sepsis and septic shock who were given IIT had a high risk of hypoglycaemia and hyperglycaemia. Among these patients even with a higher target BG level, IIT mandates an increased awareness of the occurrence of critical hypoglycaemia, which is related to the severity of the septic episode. 相似文献9.
