We report two cases of aortic valve replacement (AVR) for severe aortic stenosis (AS) before the cancer operations. Severe AS poses a great risk for noncardiac surgery. In the ACC/AHA 2007 Guideline on Perioperative Cardiovascular Evaluation and Care for Noncardiac Surgery, if the AS is symptomatic, elective noncardiac surgery should generally be postponed or canceled. Such patients require AVR before elective noncardiac surgery. On the other hand, in patients with severe AS who refuse cardiac surgery, noncardiac surgery can be performed with a mortality risk of approximately 10%. In our cases, severe AS was found in the preoperative examination. We informed them about necessary AVR before noncardiac surgery, and patients consented to our suggestion. AVR was performed around 7 days after this consent, and cancer operation was performed around 30 days after the AVR. However, there are no clear guidelines for this interval between AVR and cancer operation. In our cases the patients underwent the cardiac surgery and noncardiac surgery in a short period without serious complication in the perioperative management. It is very important to discuss among surgeon, cardiovascular surgeon, cardiologist and anesthesiologist. Especially anesthesiologist should take an important role in organizing these departments for such patients. 相似文献

A 56-year-old female who had been diagnosed with Ebstein's anomaly was admitted with cyanosis and congestive heart failure. The echocardiogram showed severe tricuspid valve incompetence, displacement of the tricuspid valve and dilatation of the atrialized portion of the right ventricle. Atrial fibrillation was detected in the electrocardiogram. She underwent tricuspid valve replacement and right atrial maze procedure. She is released from congestive heart failure and remains in sinus rhythm 48 months after the operation. 相似文献

Background
Clinical role of low-dose aspirin (LDA) in pathogenesis of gastroesophageal reflux disease is by far controversial. This can be attributed to the paucity of basic research detailing the mechanism of LDA-induced esophageal mucosal injury (EI) on underlying chronic acid reflux esophagitis (RE).Aim
The aim of this study was to clarify the effect of LDA on chronic RE in rats.Methods
Esophagitis was induced in 8-week-old male Wistar rats by ligating the border between forestomach and glandular portion with a 2–0 silk tie and covering the duodenum with a small piece of 18-Fr Nélaton catheter. Seventy-eight chronic RE rat models were divided into five treatment groups, consisting of orally administered vehicle (controls), and aspirin doses of 2, 5, 50 or 100 mg/kg once daily for 28 days. EI was assessed by gross area of macroscopic mucosal injury, severity grade of esophagitis and microscopic depth of infiltration by inflammatory cells.Results
Area of esophagitis in animals with aspirin dose of 100 mg/kg/day showed a 36.5% increase compared with controls, although it failed to achieve statistical significance (p = 0.812). Additionally, the rate of severe EI was increased in animals with aspirin dose of 100 mg/kg/day as compared with controls (p < 0.05). The grade of severity correlated with the depth of inflammation (r s = 0.492, p < 0.001).Conclusions
Maximal dose aspirin (100 mg/kg/day) contributed in exacerbating preexisting EI. LDA (2 and 5 mg/kg/day), on the other hand, did not affect chronic RE in this model. LDA seems to be safe for use in patients with chronic RE.999.

Purpose
Female athletes are at greater risk of non-contact ACL injury. Three-dimensional kinematic analyses have shown that at-risk female athletes have a greater knee valgus angle during drop jumping. The purpose of this study was to evaluate the relationship between knee valgus angle and non-contact ACL injury in young female athletes using coronal-plane two-dimensional (2D) kinematic analyses of single-leg landing.Methods
Two hundred ninety-one female high school athletes newly enrolled in basketball and handball clubs were assessed. Dynamic knee valgus was analysed during single-leg drop jumps using 2D coronal images at hallux–ground contact and at maximal knee valgus. All subjects were followed up for 3 years for ACL injury. Twenty-eight (9.6%) of 291 athletes had ACL rupture, including 27 non-contact ACL injuries. The injured group of 27 knees with non-contact ACL injury was compared with a control group of 27 randomly selected uninjured knees. The relationship between initial 2D movement analysis results and subsequent ACL injury was investigated.Results
Dynamic knee valgus was significantly greater in the injured group compared to the control group at hallux–ground contact (2.1 ± 2.4 vs. 0.4 ± 2.2 cm, P = 0.006) and at maximal knee valgus (8.3 ± 4.3 vs. 5.1 ± 4.1 cm, P = 0.007).Conclusion
The results of this study confirm that dynamic knee valgus is a potential risk factor for non-contact ACL injury in female high school athletes. Fully understanding the risk factors that increase dynamic knee valgus will help in designing more appropriate training and interventional strategies to prevent injuries in at-risk athletes.Level of evidence
