  • Surgical Treatment for Hypertrophic Obstructive Cardiomyopathy Complicated by Infective Endocarditis

    Abstract:?Objective?To analyze surgical procedures and clinical outcomes for patients with hypertrophic obstructive cardiomyopathy (HOCM) complicated by infective endocarditis.?Methods?We retrospectively analyzed clinical data of 7 patients with HOCM complicated by infective endocarditis who underwent modified Morrow procedure,removal of intracardiac vegetation,and valve replacement in Fu Wai Hospital from Sep. 2006 to Feb. 2012. There were 5 male patients and 2 female patients with their mean age of 39.80±13.60 years(ranging 21-55). Postoperative clinical outcomes were observed. Preoperative and postoperative left ventricular outflow tract (LVOT) gradients, left atrium (LA) diameter,left ventricular ejection fraction (LVEF) and heart function were compared.?Results?There was no in-hospital death and perioperative survival rate was 100% in this group. Bacteria vegetations were multiply detected on the mitral valve leaflet (7 cases), aortic valve leaflet (4 cases) and ventricular septum (1 case) with their diameter of 2-19 mm. Blood culture showed Staphylococcus aureus (3 cases),Squirrel aureus (1 case) . Postoperatively, first-degree atrioventricular block occurred in 2 patients, complete left bundle branch block in 1 patient, left anterior division block in 2 patients, and all these complications were not treated. Postoperative LVOT gradient and LA diameter were significantly lower than preoperative values (P<0.05), and cardiac function was significantly improved in these patients. All the patients underwent transthoracic echocardiography at a mean follow-up of 13.00±17.19 (1-49) months in outpatient service. The clinical symptoms of all these patients were diminished or significantly ameliorated and their quality of life was considerably improved. All the patients had NYHA classⅠorⅡ without any reintervention or death during follow-up.?Conclusion?Modified Morrow procedure and valve replacement is a good surgical strategy for patients with HOCM complicated by infective endocarditis with satisfactory early and mid-term clinical outcomes.

  • Ventricular Septal Myotomymyectomy on Hypertrophic Obstructive Cardiomyopathy and the Treatment Strategies during Perioperative Period

    Objective To summary the clinical experiences of ventricular septal myotomymyectomy on hypertrophic obstructive cardiomyopathy(HOCM) and investigate the treatment strategies during perioperative period for better clinical results. Methods From October 1996 to June 2009, 62 patients with HOCM underwent surgical treatment. There were 41 male and 21 female, aged 668 years with mean 34.05 years. The ventricular septal myotomymyectomy operation (Morrow operation or modified Morrow operation) was performed through the aortic incision under general anesthesia and hypothermic cardiopulmonary bypass (CPB). The concomitant operations included coronary artery bypass grafting (5 cases), mitral valve replacement (12 cases), mitral valve plasty(9 cases), aortic valve replacement (4 cases), tricuspid valve plasty(2 cases) and ductus arteriosus closure (2 cases). During the perioperative period, the patients were examined by echocardiography or transesophageal echocardiograph(TEE), electrocardiogram or dynamic echocardiogram and chest radiography. Left atrial diameter,left ventricular enddiastolic [CM(159mm]diameter,left ventricular outflow tract (LVOT) pressuregradient,interventricular septal thickness, ejection fraction[CM)](EF), the changes of mitral valve construction and function were evaluated. Results The time of CPB and aortic occlusion were 104.23±47.14 min and 66.76±36.32 min, respectively. The endotracheal intubation time was 13.23±11.76 h and the postoperative intensive care unit(ICU) stay was 42.53±37.41 h. Four patients died and the mortality was 6.45%(4/62). The main causes of death included septic shock complicated with acute renal failure(1 case), refractory arrhythmia, ventricular fibrillation, atrial flutter complicated with severe low cardiac output syndrome (1 case), severe acute renal failure(1 case) and Ⅲ°atrioventricular(AV) block complicated with low cardiac output syndrome(1 case). Postoperative left atrial diameter (34.56±6.45 mm vs.43.46±7.21 mm,t=6.948,P=0.000), left ventricular enddiastolic diameter (37.14±6.31 mm vs.42.03±6.23 mm,t=3.145,P=0.020), LVOT pressure gradient (23.54±17.78 mm Hg vs. 103.84±44.04 mm Hg,t=13.618,P=0.000) and interventricular septal thickness (17.12±5.67 mm vs.26.93±5.23 mm, t=10.694,P=0.000) decreased significantly compared with those before operation. There was no mitral valve regurgitation, or only mild mitral valve regurgitation. No systolic anterior motion(SAM) was found. The main postoperative arrhythmias included complete left bundle branch block, intraventricular block, complete atrioventricular block and atrial fibrillation. All the 58 cases were cured and discharged. Fiftythree cases were followed up for 3 months12 years, and 5 cases were lost. No death, complication and reoperation were found. Symptoms relieved significantly. The cardiac function was in New York Heart Association grade Ⅰ-Ⅱ. The quality of life improved significantly. Conclusion Most patients with HOCM can achieve satisfactory relief of LVOT obstruction and SAM via ventricular septal myotomymyectomy. The main arrhythmias after operation are bundle branch block and atrial fibrillation. Satisfactory effects can be achieved by accurate surgical technique and effective drug treatments.

  • EFFECTS OF MECHANICAL STIMULATION ON EXPRESSION OF AUTOANTIGENS IN MYOBLASTS

    Objective To explore the effects of mechanical stimulation on the expression of autoantigens in myoblasts. Methods According to different processing methods, C2C12 cells were divided into the experimental group and control group; the experimental group was divided into 4 subgroups: 2-, 4-, and 6-day and 1-day stretch groups. In 2-, 4-, and 6-day stretch groups, mechanical loading was added on the C2C12 cells at a stretching frequency of 0.25 Hz and cellular deformation amplitude of 10%, 2 hours a day for 2, 4, and 6 days respectively by Flexercell 5000 strain unit, and at a stretching frequency of 1 Hz and cellular deformation amplitude of 15% for 1 hour in 1-day stretch group. In the control group, the cells were routinely cultured for 1, 2, 4, and 6 days (1-, 2-, 4-, and 6-day control). The cells were observed by inverted phase contrast microscope. The cell proliferation was detected by flow cytometry; the expressions of autoantigens were detected by Western blot method, including the Ku/the catalytic subunit of DNA-dependent protein kinase (DNA-PKcs), U1-70 (A part of ATP-dependent DNA helicase II), histidyl tRNA synthetase (HRS), and Mi-2 (reconfigurable components deacetylase complexes of NuRD). Results The exfoliated cells were found in 1-day stretch group, but no exfoliated cell was seen in the control group for 1-day culture. The cells proliferated more obviously in 2-day stretch group than in the control group for 2-day culture; cell differentiation was found in 4-day stretch group, and cell fusion in 6-day stretch group, which were similar to those in the control group for 4- and 6-day culture. After single stretching, cell apoptosis was found in 1-day stretch group, showing no significant difference in the relative DNA proliferation index (DPI) when compared with DPI of control group for 1-day culture (t=0.346, P=0.747). After cyclic stretching, DPIs of 2- and 4- day stretch groups were significantly increased when compared with those of the control group for 2- and 4-day culture (P lt; 0.05), but no significant difference was found between control group for 6-day culture and 6-day stretch group (t=1.191, P=0.303). Compared with the control group for 2-day culture, the relative protein expression of autoantigens (DNA-Pkcs, Mi-2, HRS, and U1-70) in 2-day stretch group decreased significantly (P lt; 0.05), but no significant difference was found between control group for 4-day culture and 4-day stretch group (P gt; 0.05). The relative protein expressions of autoantigens in 4-day stretch group significantly increased when compared with those of 2-day stretch group (P lt; 0.05), but the relative protein expressions of autoantigens in the control group for 4-day culture significantly decreased when compared with those of the control group for 2-day culture (P lt; 0.05). Conclusion Short-term mechanical stimulation can inhibit the expressions of autoantigens in myoblasts, but with the time prolonging, cell differentiation and fusion and adaptation to mechanical stimulation would result in diminished inhibitory effect.

    Objective To observe the effect of BMSCs on the cardiac function in diabetes mellitus (DM) rats through injecting BMSCs into the ventricular wall of the diabetic rats and investigate its mechanism. Methods BMSCs isolated from male SD rats (3-4 months old) were cultured in vitro, and the cells at passage 5 underwent DAPI label ing. Thirty clean grade SD inbred strain male rats weighing about 250 g were randomized into the normal control group (group A), the DM group (group B), and the cell transplantation group (group C). The rats in groups B and C received high fat forage for 4 weeks and the intraperitoneal injection of 30 mg/kg streptozotocin to made the experimental model of type II DM. PBS and DAPI-labeledpassage 5 BMSCs (1 × 105/μL, 160 μL) were injected into the ventricular wall of the rats in groups B and C, respectively. After feeding those rats with high fat forage for another 8 weeks, the apoptosis of myocardial cells was detected by TUNEL, the cardiac function was evaluated with multi-channel physiology recorder, the myocardium APPL1 protein expression was detected by Western blot and immunohistochemistry test, and the NO content was detected by nitrate reductase method. Group C underwent all those tests 16 weeks after taking basic forage. Results In group A, the apoptosis rate was 6.14% ± 0.02%, the AAPL1 level was 2.79 ± 0.32, left ventricular -dP/dt (LV-dP/dt) was (613.27 ± 125.36) mm Hg/s (1 mm Hg=0.133 kPa), the left ventricular end-diastol ic pressure (LVEDP) was (10.06 ± 3.24) mm Hg, and the NO content was (91.54 ± 6.15) nmol/mL. In group B, the apoptosis rate was 45.71% ± 0.04%, the AAPL1 level 1.08 ± 0.24 decreased significantly when compared with group A, the LVdP/ dt was (437.58 ± 117.58) mm Hg/s, the LVEDP was (17.89 ± 2.35) mm Hg, and the NO content was (38.91±8.67) nmol/mL. In group C, the apoptosis rate was 27.43% ± 0.03%, the APPL1 expression level was 2.03 ± 0.22, the LV -dP/dt was (559.38 ± 97.37) mm Hg/ s, the LVEDP was (12.55 ± 2.87) mm Hg, and the NO content was (138.79 ± 7.23) nmol/ mL. For the above mentioned parameters, there was significant difference between group A and group B (P lt; 0.05), and between group B and group C (P lt; 0.05). Conclusion BMSCs transplantation can improve the cardiac function of diabetic rats. Its possible mechanismmay be related to the activation of APPL1 signaling pathway and the increase of NO content.
