  • Influence of CYP2C9 *3, VKORC1-1639 G>A and CYP4F2 rs2108622 Genetic Polymorphisms on Warfarin Dosage

    Objective To investigate the influence of CYP2C9 3,VKORC1-1639 G>A and CYP4F2 rs2108622 genetic polymorphisms on warfarin dosages of patients after heart valve replacement. Methods A total of 133 patients undergoing heart valve replacement in the Department of Cardiovascular Surgery of Fujian Provincial Hospital from November 2011 to August 2012 were included in this study. Polymerase chain reaction(PCR)gene sequencing was performed to detect CYP2C9 3,VKORC1-1639 G>A and CYP4F2 rs2108622 genetic polymorphism of these 133 patients. Patients were grouped according to their genotypes,and average warfarin dosages were compared between different genotype groups. Results The frequencies of CYP2C9 3 AA,AC and CC were 127 patients,6 patients and 0 patient respectively,and average daily warfarin dosages were 3.75 mg and 2.13 mg respectively which were statistically different between differentCYP2C9 3 genotypes (P<0.05). The frequencies of VKORC1-1639 G>A GG,GA and AA were 3 patients,32 patientsand 98 patients respectively,and average daily warfarin dosages were 6.00 mg,4.50 mg and 3.00 mg respectively which were statistically different between different VKORC1-1639 G>A genotypes (P<0.05). The frequencies of CYP4F2 rs 2108622 CC,CT and TT were 67 patients,59 patients and 7 patients respectively,and average daily warfarin dosages were 3.00 mg,3.75 mg and 4.50 mg respectively which were statistically different between different CYP4F2 rs2108622 genotypes(P<0.05). Conclusion CYP2C9 3,VKORC1-1639 G>A and CYP4F2 rs2108622 genetic polymorphisms are associated with individual difference of warfarin dosages of patients after heart valve replacement.

  • Real-time Three-dimensional Echocardiography (RT-3DE) Application in Evaluation of Left Ventricular Motion in Patients with Rheumatic Mitral Stenosis

    ObjectiveTo evaluate myocardial segmental motion function in left ventricular of patients with rheumatic mitral stenosis by using the technology of real-time three-dimensional echocardiography (RT-3DE). MethodsWe retrospectively analyzed the clinical data of 14 patients with rheumatic mitral stenosis between October and November 2014 in our hospital as a trial group. There were 4 males and 10 females with a mean age of 50.9±9.0 years ranging from 34 to 64 years. We chose 11 healthy individuals as a control group. There were 7 males and 4 females with a mean age of 49.5±9.7 years ranging from 32 to 67 years. Both the two groups were subjected to myocardial performance evaluation using two-dimensional echocardiography (2DE) and real-time three-dimensional echocardiography (RT-3DE) to examine the left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end systolic volume (LVESV), longitudinal strain, circumferential strain, area strain, and lateral strain of each left ventricular myocardial segments. Result RT-3DE detected that the trial group had significantly lower values of LVEF, LVEDV and LVESV than those of the control group (P < 0.05). RT-3DE also revealed that the trial group had a significantly weaker longitudinal strain than the control group (P < 0.05). ConclusionRT-3DE is an accurate technology for assessing myocardial motion and function in patients with rheumatic mitral valve disease.

  • 心脏生物瓣膜置换术126例临床分析

    目的 总结心脏生物瓣膜置换术的临床经验和手术效果。 方法 回顾性分析2008年6月至2010年11月福建省立医院126例患者行心脏生物瓣膜置换手术的临床资料,其中男66例,女60例;年龄27~85 (67.6±10.8)岁。心功能分级(NYHA)Ⅱ~Ⅳ级。风湿性二尖瓣狭窄伴关闭不全101例,心瓣膜退行性变二尖瓣关闭不全20例,二尖瓣腱索断裂导致二尖瓣关闭不全5例;行二尖瓣置换术(MVR)75例,三尖瓣置换术2例,主动脉瓣置换术(AVR)30例,AVR+MVR(双瓣膜置换术,DVR) 19例。 结果 行MVR升主动脉阻断时间(40.5±7.8) min,体外循环时间(85.3±10.1) min;行AVR升主动脉阻断时间(70.6±12.4) min ,体外循环时间(142.3±15.6) min;行DVR 升主动脉阻断时间(103.5±18.4) min ,体外循环时间(182.3±21.8) min。全组无手术死亡。住院时间(25.7±5.9) d,住重症监护室(ICU)时间(2.5±1.9) d。术后出院前复查心脏彩色超声心动图,未见瓣膜关闭不全。 结论 生物瓣膜具有较高的手术安全性,采用生物瓣的手术风险与机械瓣无异,具有较好的疗效。

  • Early to Mid-term Results of Modified Aortoplasty with External Wrap for Aneurysmal Dilatation of the Ascending Aorta

    ObjectiveTo summarize clinical experience and early to mid-term results of modified aortoplasty with external wrap for aneurysmal dilatation of the ascending aorta with or without heart valve disease. MethodsClinical data of 27 patients with aneurysmal dilatation of the ascending aorta who underwent modified aortoplasty with external wrap in Department of Cardiovascular Surgery, Fujian Provincial Hospital from January to October 2003 were retrospectively analyzed. There were 19 male and 8 female patients with their age of 35-71 (57±9)years and body weight of 42-90 (59±11)kg.There were 23 patients with aortic valve disease including 3 patients with bicuspid aortic valve. There were 4 patients in New York Heart Association function class Ⅰ, 9 patients in class Ⅱ, 12 patients in class Ⅲ, and 2 patients in class Ⅳ. Preoperative ascending aortic diameter (AAOD)was 40.0-59.1 (46.4±4.8)mm, left ventricular end-diastolic diameter was 42.5-70.7 (56.9±8.3)mm, and left ventricular ejection fraction (LVEF)was 57.7%±8.0%. Patients were followed up with echocardiography to examine changes of AAOD and left ventricle. ResultsCardiopulmonary bypass (CPB)time was 121.2±52.6 minutes, and aortic cross-clamping time was 70.6±29.7 minutes. Two patients received modified aortoplasty without CPB. There was no in-hospital death.Among the 25 patients who received modified aortoplasty under CPB, 1 patient had cerebral infarction and another patient had hypotension and arrhythmia postoperatively.Postoperative AAOD (36.3±3.4 mm)was significantly smaller than preoperative AAOD (46.4±4.8 mm, t=1.675, P < 0.05). Twenty-four patients were followed up from 1.0 to 120.5 months (average, 35.5 months). During follow-up, no cardiac-related death or reoperation was found. Two patients died of pneumonia, and another 2 patients died of cerebral hemorrhage. One patient had upper gastrointestinal bleeding. Aneurysmal dilatation of the ascending aorta recurred in 1 patient 3 years after discharge with AAOD of 49.9 mm. AAOD at 1 year (40.3±4.3 mm)and 3 years (40.3±5.6 mm)after discharge were significantly smaller than preoperative and postoperative AAOD (P < 0.05). ConclusionModified aortoplasty with external wrap is a good surgical procedure for aneurysmal dilatation of the ascending aorta with or without valve disease, and early to mid-term results are satisfactory.
