Background Extended trans septal (ETS) approach for mitral valve surgery often divides the artery to the Sino-Atrial node. The clinical
implication of this is contentious. We analyzed our early results with ETS approach.
Methods Between June 1998 and September 2003 eleven patients underwent mitral valve surgery by ETS approach. Six were females. Age
ranged from 19 years to 67 years (median 40 years). Six underwent mitral valve replacement (MVR). Four underwent aortic and
mitral (double) valve replacement (DVR). One had mitral valve repair. Three had additional procedures (tricuspid valve repair=1,
Coronary artery bypass=1, Aorto bifemoral graft=1). Cardiopulmonary bypass ranged from 64 minutes to 77 minutes (median 72
minutes) for MVR and 112 minutes to 178 minutes (median 140 minutes) for DVR. Aortic cross clamp times ranged from 39 minutes
to 52 minutes (median 47 minutes) for MVR and 74 minutes to 120 minutes (median 95 minutes) for DVR.
Results There was no mortality or morbidity attributed to the ETS approach. One early death in emergency DVR was due to heart failure.
Three patients needed seqeuntial pacing in the immediate post-operative period. Nine out of ten survivors were back to their
preoperative rhythms on hospital discharge (6 sinus rhythm; 3 atrial fibrillation). One patient with preoperative trifascicular
block who underwent reoperation to fix a paravalvular mitral leak needed a permanent pacemaker (VVI). The follow-up ranged
from 1 month to 64 months (median 6 months) and is 100% complete. There was no late death or new arrhythmia.
Conclusions Extended trans septal approach is safe. It gives excellent exposure of the mitral valve. division of the sinus node artery
is not deleterious in the short to intermediate term.

Objective: Tricuspid valve (TV) surgery is usually performed as a concomitant reconstruction procedure in addition to the correction of other cardiac pathologies. Isolated tricuspid procedures are exceptionally rare. Prosthetic valve replacement is also seldom required. Generally, these patients face a high risk of operative mortality and long-term outcome is poor. In this study we reviewed our experience with TV surgery focusing on risk factors for operative mortality, long-term outcome and incidence of valve related complications Methods: Retrospective analysis of 416 consecutive patients >18 years with acquired TV disease operated on between 1974 and 2003. The follow-up is 97% complete (mean 5.9 ± 6.3 years). Three hundred and sixty-six patients (88%) underwent TV surgery with concomitant mitral (n = 340) or aortic (n = 100) valve surgery. The tricuspid valve was repaired in 310 patients (74.5%) and replaced in 106 (25.5%). A biological prosthesis was used in 68 patients (64%). Mean age at repair and replacement was 61 ± 12.5 and 50 ± 11.3 years, respectively (p < 0.001). Results: Overall 30-day mortality was 18.8% (78/416) and decreased from 33.3% (1974–1979) to 11.1% (2000–2003) (p ≤ 0.0001). Thirty-day mortality after TV repair and replacement was 13.9% (43/310) and 33% (35/106), respectively (p ≤ 0.001). Cox regression analysis revealed TV replacement as an independent predictor of 30-day mortality. Ten-year actuarial survival after TV repair and replacement was 47 ± 3.5% and 37 ± 4.8%, respectively (p = 0.002). Forty-five patients (10.8%) required a TV re-operation after 7.7 ± 5.1 years. Freedom from TV re-operation 10 years after TV repair and replacement was 83 ± 3.6% and 79 ± 6.1%, respectively (p = 0.092). Conclusions: Patients who require tricuspid valve surgery constitute a high-risk group. Tricuspid valve repair is associated with better perioperative and long-term outcome than valve replacement. However, patients undergoing replacement showed a significant higher incidence of risk factors for operative mortality. The incidence of re-operation is low with no significant difference when the tricuspid valve has been repaired or replaced. When valve replacement is necessary we recommend the use of a biological prosthesis considering the poor long-term survival. 相似文献

ObjectiveUsing a large national database, we sought to better define the relationship between obesity measures and early clinical outcomes following mitral valve surgery for degenerative disease.MethodsFor the outcomes of in-hospital mortality, postoperative cerebrovascular event (CVA), and deep sternal wound infection (DSWI), a retrospective cohort study was performed using data acquired from the United Kingdom National Adult Cardiac Surgery Audit. Multivariable Cox proportional hazard regression modeling was used to investigate associations with individual measures of obesity. Progressively adjusted body mass index (BMI)-specific hazard ratios (HRs) were plotted against mean BMI values in each World Health Organization category using floated variances to investigate specific shapes of association.ResultsMultivariable Cox proportional hazard modeling failed to demonstrate an association between mortality and an increase in BMI of 5 points (HR, 0.93, 95% confidence interval [CI], 0.81-1.07), a BMI quintile increase (HR, 0.98; 95% CI, 0.90-1.07), or being classed “obese” by World Health Organization standards (HR, 1.03; 95% CI, 0.74-1.42). A 5-point BMI increase was associated with an increased hazard of DSWI (HR, 1.38; 95% CI, 1.08-1.77) but was not associated with perioperative CVA (HR, 1.05; 95% CI, 0.91-1.21). The shape of association between BMI and mortality appeared approximately U-shaped. DSWI appeared linear, whereas CVA demonstrated an inverted U, or a possible hourglass.ConclusionsAlthough individual measures of obesity were not associated with an increased mortality risk on regression modeling, the U-shaped relationship between mortality and increasing BMI demonstrates lower mortality risks in lower obesity classes. Increasing BMI was associated with an increased hazard for DSWI. 相似文献

Objectives
An increasing number of octogenarians are referred to undergo mitral valve surgery for degenerative disease, and percutaneous approaches are being increasingly used in this subgroup of patients. We sought to determine the survival and its predictors after Mitral Valve Surgery in Octogenarians (MiSO) in a multicenter UK study of high-volume specialized centers.Methods
Pooled data from 3 centers were collected retrospectively. To identify the predictors of short-term composite outcome of 30 days mortality, acute kidney injury, and cerebrovascular accident, a multivariable logistic regression model was developed. Multiple Cox regression analysis was performed for late mortality. Kaplan–Meier curves were generated for long-term survival in various subsets of patients. Receiver operating characteristic analysis was done to determine the predictive power of the logistic European System for Cardiac Operative Risk Evaluation.Results
A total of 247 patients were included in the study. The median follow-up was 2.9 years (minimum 0, maximum 14 years). A total of 150 patients (60.7%) underwent mitral valve repair, and 97 patients (39.3%) underwent mitral valve replacement. Apart from redo cardiac surgery (mitral valve repair 6 [4%] vs mitral valve replacement 11 [11.3%], P = .04) and preoperative atrial fibrillation (mitral valve repair 79 [52.6%] vs mitral valve replacement 34 [35.1%], P < .01), there was no significant difference in terms of any other preoperative characteristics between the 2 groups. Patient operative risk, as estimated by logistic European System for Cardiac Operative Risk Evaluation, was lower in the mitral valve repair group (10.2 ± 11.8 vs 13.7 ± 15.2 in mitral valve replacement; P = .07). No difference was found between groups for duration of cardiopulmonary bypass and aortic crossclamp times. The 30-day mortality for the whole cohort was 13.8% (mitral valve repair 4.7% vs mitral valve replacement 18.6%; P < .01). No differences were found in terms of postoperative cerebrovascular accident (2% vs 3.1%; P = .9), acute kidney injury requiring dialysis (6.7% vs 13.4%; P = .12), and superficial or deep sternal wound infection (10% vs 16.5%, P = .17; 2% vs 3.1%, P = .67, respectively). The final multiple regression model for short-term composite outcome included previous cardiac surgery (odds ratio [OR], 4.47; 95% confidence interval [CI], 1.37-17.46; P = .02), intra-aortic balloon pump use (OR, 4.77; 95% CI, 1.67-15.79; P < .01), and mitral valve replacement (OR, 7.7; 95% CI, 4.04-14.9; P < .01). Overall survival for the entire cohort at 1, 5, and 10 years was 82.4%, 63.7%, and 45.5% (mitral valve repair vs mitral valve replacement: 89.9% vs 70.7% at 1 year, 69.6% vs 54% at 5 years, and 51.8% vs 35.5% at 10 years; P = .0005). Cox proportional hazard model results showed mitral valve replacement (hazard ratio, 1.88; 95% CI, 1.22-2.89; P < .01) and intra-aortic balloon pump use (hazard ratio, 2.54; 95% CI, 1.26-5.13; P < .01) to be independent predictor factors affecting long-term survival. Logistic European System for Cardiac Operative Risk Evaluation did not perform well in predicting early mortality (area under the curve, 0.57%).Conclusions
In octogenarians, mitral valve repair for degenerative disease is associated with good survival and remains the gold standard, whereas mitral valve replacement is still associated with significant mortality. Logistic European System for Cardiac Operative Risk Evaluation was unable to predict early mortality in our cohort of patients. Larger international multicenter registries are required to optimize the decision-making process in such a high-risk subgroup. 相似文献7.

The importance of art studies in the training of plastic surgeons has not been well recognized. Presently, very few medical schools offer courses on art or include it in the humanities. Because the study of art is a great experience that helps to develop the trained eye, the inclusion of art in medical education is recommended. For plastic and aesthetic surgeons, art knowledge can greatly add to the development of surgical skill. Courses in drawing, modeling, and casting are recommended along with lectures or seminars on art appreciation.Delivered as the Nojarova Lecture at the New York Academy of Medicine, the New York Regional Society of Plastic and Reconstructive Surgery, March 3, 1990.

The aim of the study is to assess satisfaction with urogynecology education among obstetrics and gynecology residents. An
Internet-based survey was designed to obtain a cross-sectional sample of third- and fourth-year residents. Didactic and surgical
training as well as perceived surgical competency were assessed. Responses were received from 205 residents for this convenience
sample. Nearly half (46%) of the respondents were unsatisfied with urogynecology resident education. There was no significant
difference between respondents from academic programs and community programs with regard to overall satisfaction, the opportunity
to work with the presence of a fellowship-trained urogynecologist or having a dedicated urogynecology rotation. Respondents
were more satisfied with their education if they did a urogynecology rotation or worked with a fellowship-trained urogynecologist.
Female pelvic medicine and reconstructive surgery fellows were involved in the education of 23.9% of the respondents. Most
respondents indicated comfort performing cystoscopy, anterior and posterior repairs, and McCall’s culdoplasty following graduation.
Overall, respondents indicated that residency training in urogynecology is less and later than desired, although they did
feel competent at some urogynecologic surgeries.
This was an unfunded study. This article was also presented in abstract form as a poster at APGO–CREOG in March 2005. 相似文献

Background Current assessments using the fundamentals of laparoscopic surgery (FLS) tasks are labour intensive and depend heavily on
expert raters. Hand motion analysis may offer an alternative method of objective evaluation of FLS performance.
Purpose The aim of this study was to assess whether a correlation exists between the expert rated assessments of the FLS tasks and
computer-based assessment of motion efficiency using the Imperial College surgical assessment device (ICSAD).
Methods We recruited 26 volunteer subjects who were stratified into three experience groups: juniors (PGY1–3) (N = 13), seniors (PGY4,5) (N = 7) and staff surgeons (N = 6). All subjects performed four FLS tasks: (1) peg transfer, (2) pattern cut, (3) endoloop and (4) intracorporeal suturing.
Performance was assessed by both standard FLS expert rating and motion analysis using ICSAD. Group differences were analyzed
using the Kruskal–Wallis test, and Spearman coefficient analyses were employed to compare FLS and ICSAD scores.
Results FLS expert-derived scores discriminated effectively between experience groups for all tasks (p < 0.05). Motion efficiency scores discriminated between experience groups for tasks 1, 3 and 4 for number of movements (p < 0.05), tasks 1 and 4 for total distance (p < 0.05) and tasks 1, 2, 3 and 4 for total time (p < 0.005). There was a significant correlation between total FLS expert scores and the motion efficiency metrics of total
distance, number of movements and total time (Spearman coefficient and p values of 0.81, < 0.001; 0.76; < 0.001; and 0.93, < 0.001, respectively).
Conclusion There is a high correlation between FLS standard scoring and motion efficiency metrics. The use of ICSAD for the objective
assessment of FLS tasks may in the future offer an adjunctive method of evaluation. ICSAD metrics are potentially less labour
intensive due to the instant and fully automated computerized scoring that it provides.

Background
National Health Service (NHS) reforms have changed the structure of postgraduate healthcare education and training. With a Government mandate that promotes multi-professional education and training aligned with policy driven initiatives, this article highlights concerns over the impact that these changes may have on surgical training.Discussion
The creation of Health Education England (HEE) and its local education and training boards (LETBs), which are dominated by NHS healthcare providers, should result in greater accountability of employers in workforce planning, enhanced local responsibility and increased transparency of funding allocation. However, these changes may also create a potential poacher-turned-gamekeeper role of employers, who now have responsibility for junior doctors’ training. Analysis of LETB membership reveals a dearth of representation of surgeons, who comprise only 2% of board members, with the input of trainees also seemingly overlooked. A lack of engagement with the LETBs by the independent sector is a concern with increasing numbers of training opportunities potentially being lost as a result.The new system also needs to recognise the specific training needs required by the craft specialties given the demands of technical skill acquisition, in particular regarding the provision of simulation training facilities and trainer recognition. However, training budget cuts may result in a disproportionate reduction of funding for surgical training. Surgical training posts will also be endangered, opportunities for out-of-programme experience and research may also decline and further costs are likely to be passed onto the trainee.Summary
Although there are several facets to the recent reforms of the healthcare education and training system that have potential to improve surgical training, concerns need to be addressed. Engagement from the independent sector and further clarification on how the LETBs will be aligned with commissioning services are also required. Surgical training is in danger of taking a back seat to Government mandated priorities. Representation of trainees and surgeons on LETB committees is essential to ensure a surgical viewpoint so that the training needs of the future consultant workforce meet the demands of a 21st century health service. 相似文献16.

OBJECTIVESSickle-cell disease (SCD) patients are considered to be at high risk from open-heart surgery. This study assessed the role of a simple sickling-prevention protocol.METHODSPerioperative non-specific and SCD-specific morbidity and 30-day mortality are investigated in a retrospective cohort study on patients undergoing isolated mitral valve surgery. Patients with and without SCD were compared. In the SCD cohort, a bundle of interventions was applied to limit the risk of sickling: ‘on-demand’ transfusions to keep haemoglobin levels of around 7–8 g/dl, cardiopulmonary bypass (CPB) with higher blood flow and perfusion temperature, close monitoring of acid–base balance and oxygenation.RESULTSTwenty patients with and 40 patients without SCD were included. At baseline, only preoperative haemoglobin levels differed between cohorts (8.1 vs 11.8 g/dl, P < 0.001). Solely SCD patients received preoperative transfusions (45.0%). Intraoperative transfusions were significantly larger in SCD patients during CPB (priming: 300 vs 200 ml; entire length: 600 vs 300 ml and 20 vs 10 ml/kg). SCD patients had higher perfusion temperatures during CPB (34.7 vs 33.0°C, P = 0.01) with consequently higher pharyngeal temperature, both during cooling (34.1 vs 32.3°C, P = 0.02) and rewarming (36.5 vs 36.2°C, P = 0.02). No mortality occurred, and non-SCD-specific complications were comparable between groups, but one SCD patient suffered from perioperative cerebrovascular accident with seizures, and another had evident haemolysis.CONCLUSIONSSCD patients may undergo open-heart surgery for mitral valve procedures with an acceptable risk profile. Simple but thoughtful perioperative management, embracing ‘on-demand’ transfusions and less-aggressive CPB cooling is feasible and probably efficacious. 相似文献

We report the rare case of a 48-year-old woman with a cardiac intimal sarcoma occupying the mitral valve and the left atrial roof. We resected the tumour in one block without residual lesions. The anterior mitral annulus and left atrial roof were serially repaired with the bovine pericardium, and a mechanical prosthesis was implanted in the reconstructed mitral annulus. The patient remains alive without recurrence for more than 1 and a half years postoperatively. We performed radical surgery for a mitral valve intimal sarcoma, and serial patch repair of the anterior mitral annulus and left atrial roof was a useful technique. 相似文献

ObjectiveVagus nerve stimulation (VNS) therapy has been used for more than two decades to treat drug resistant epilepsy and depression and most recently received FDA approval for stroke rehabilitation. Expanding indications will renew the interest in the technique and increase the number of surgeons to be trained. The aim of this study was to survey surgeons with substantial expertise on optimal teaching and training approaches.MethodsAnonymous forms comprising 16 questions were sent by e-mail to surgeons with substantial expertise. Statistical analyses were used to compare the answers of the most experienced surgeons (>5 years) with the less experienced ones (<5 years).ResultsFully-completed forms were collected from 57 experts from 20 countries. The placement of the helical coils was deemed to be the most difficult step by 36 (63.2%) experts, and the use of optical magnification during this step was deemed necessary by 39 (68.4%) experts. Vocal cord palsy should be largely avoidable with proper surgical technique according to 44 (77.2%) experts. The teaching tool considered the most useful was mentoring (38, 66.7%). The future of VNS surgery teaching was deemed to be in anatomical workshops (29, 50.9%) and surgical simulation (26, 45.6%). Overall, answers did not vary significantly according to experience.ConclusionsVNS surgery should be mastered by actively participating in dedicated practical training courses and by individual mentoring during actual surgery, which is still the best way to learn. This study highlights the need for a formal training course and possible specific accreditation. 相似文献
