ABSTRACT

Objective: To evaluate long-term clinical outcomes of consecutive patients treated with coronary artery bypass grafting (CABG) and percutaneous coronary intervention(PCI) with drug-eluting stents(DES) for ostial/shaft lesions in unprotected left main coronary artery(ULMCA). Method: A total of 259 patients with isolated ostial/midshaft lesions in unprotected left main coronary artery were enrolled consecutively who received DES implantation or underwent CABG between January 2003 and July 2009 in Beijing Anzhen Hospital. The endpoints of the study were death, repeat revascularization, myocardial infarction (MI) and stroke. Time to the primary endpoint was evaluated according to the Kaplan-Meier method, and the log-rank test was applied to compare the incidence of the endpoint. Adjusted risks for adverse outcomes were compared by multivariate Cox proportional hazard regression analyses. Results: A total of 259 patients were included, including 149 in PCI group and 110 in CABG group. And 193(74.5%) cases were males.The age was (61.4±9.8) years old. The median follow-up was 10.1 years (interquartile range 8.3 to 11.2 years) in the overall patients. There were no significant difference for the incidence of death [37.0% vs. 43.1% ,P=0.143] , MI [34.0% vs. 19.4% ,P=0.866], stroke [6.4% vs. 11.7% , P=0.732], repeart revascularization [33.6% vs. 39.9% ,P=0.522] between PCI group and CABG group before multivariate adjusting,according to the incidence calculated with Kaplan-Meier. After adjusting covariates such as age, left ventricular ejection fraction(LVEF) and serum creatine with multivariate Cox hazard regression model, there was still no significant difference between the two groups. Conclusions: PCI with DES is as effective and safe as CABG in patients with left main ostium/shaft lesion during a median follow-up of 10.1 years.

ABSTRACT

To examine the outcomes of surgical treatment in patients of type Stanford A aortic dissection with Kommerell's diverticulum. From January 2009 to August 2017, patients of type Stanford A aortic dissection with Kommerell's diverticulum who underwent the Sun procedure were enrolled. Patient demographic, preoperative, intraoperative, early morbidity and mortality data were collected from medical and electronic patient records. Clinical follow-up data, including late morbidity and mortality, were obtained by telephone interview with the patient. A total of 13 patients (11 males and 2 females; mean age 47 years) were included. The mean maximum diameter of Kommerell's diverticulum was (21.8±7.7) mm. The Kommerell's diverticulum was repaired by direct suture of the orifice in 3 patients, ligation of the aberrant right subclavian artery in 9 patients, and suture and ligation in 1 patient, respectively. No perioperative death occurred. One patient underwent a reexploration for bleeding. There were 2 late deaths: unknown reason in 1 patient and septic shock secondary to renal abscess in 1 patient. Reintervention was performed in one patient for a persistent type Ⅱ endoleak. The Sun procedure with femoral artery cannulation for cardiopulmonary bypass, unilateral carotid artery cannulation for selective cerebral perfusion and ligation of aberrant right subclavian artery on the right side of the trachea is an appropriate therapeutic strategy for patients of type Stanford A aortic dissection with Kommerell's diverticulum.

ABSTRACT

In recent years,the CTLA-4 immunoglobulin biologics,a negative regulator in the immune system,have been obtained due attention in autoimmune diseases,transplantation rejection,and antineoplastic agents.CTLA-4 can inhibit T cell activation,reduce the expression of RANKL and other cytokines through regulating immune response,and effectively alleviate the process of bone resorption.According to previous study,CTLA-4 was involved in osteoclast-induced bone destruction and bone remodeling.In this review,the effect of CTLA-4 on the autoimmune diseases,on the osteoclast formation,and on the alveolar bone remodeling in the periodontal tissue was involved,and the related research were also evaluated to look forward to possible future basic research and clinical application direction.

ABSTRACT

<p><b>BACKGROUND</b>There are limited data on longer-term outcomes (>5 years) for patients with unprotected left main coronary artery (ULMCA) disease who underwent percutaneous coronary intervention (PCI) in the drug-eluting stents (DES) era. This study aimed at comparing the long-term (>5 years) outcomes of patients with ULMCA disease underwent PCI with DES and coronary artery bypass grafting (CABG) and the predictors of adverse events.</p><p><b>METHODS</b>All consecutive patients with ULMCA disease treated with DES implantation versus CABG in our center, between January 2003 and July 2009, were screened for analyzing. A propensity score analysis was carried out to adjust for potential confounding between the two groups.</p><p><b>RESULTS</b>Nine hundred and twenty-two patients with ULMCA disease were enrolled for the analyses (DES = 465 vs. CABG = 457). During the median follow-up of 7.1 years (interquartile range 5.3-8.2 years), no difference was found between PCI and CABG in the occurrence of death (P = 0.282) and the composite endpoint of cardiac death, myocardial infarction (MI) and stroke (P = 0.294). Rates of major adverse cardiac and cerebrovascular events were significantly higher in the PCI group (P = 0.014) in large part because of the significantly higher rate of repeat revascularization (P < 0.001). PCI was correlated with the lower occurrence of stroke (P = 0.004). Multivariate analysis showed ejection fraction (EF) (P = 0.012), creatinine (P = 0.016), and prior stroke (P = 0.031) were independent predictors of the composite endpoint of cardiac death, MI, and stroke in the DES group, while age (P = 0.026) and EF (P = 0.002) were independent predictors in the CABG group.</p><p><b>CONCLUSIONS</b>During a median follow-up of 7.1 years, there was no difference in the rate of death between PCI with DES implantation and CABG in ULMCA lesions in the patient cohort. CABG group was observed to have significantly lower rates of repeat revascularization but higher stroke rates compared with PCI. EF, creatinine, and prior stroke were independent predictors of the composite endpoint of cardiac death, MI, and stroke in the DES group, while age and EF were independent predictors in the CABG group.</p>

ABSTRACT

<p><b>BACKGROUND</b>Optimizing treatment outcomes for depression requires understanding of how evidence-based treatments are utilized in clinical practice. Antipsychotic medications concurrent with antidepressant treatment are frequently used in major depression, but few studies have investigated trends and patterns of their use over time. This study aimed to examine the prescription patterns of antipsychotic medications for major depression in China from 2002 to 2012 and their association with treatment satisfaction and quality of life (QOL).</p><p><b>METHODS</b>A total of 3655 subjects with major depression treated in 45 Chinese psychiatric hospitals/centers nationwide were interviewed between 2002 and 2012. Patients' socio-demographic and clinical characteristics including psychopathology, medication side effects, satisfaction with treatment and QOL were recorded using a standardized protocol and data collection.</p><p><b>RESULTS</b>The frequency of antipsychotic use was 24.9% in the whole sample; the corresponding figures were 17.1%, 20.3%, and 32.8% in 2002, 2006, and 2012, respectively (χ2 = 90.3, df = 2, P < 0.001). Multiple logistic regression analyses revealed that patients on concurrent antipsychotics had significantly more delusions or hallucinations, longer illness duration, greater side effects, and more likely to be treated as inpatients and in major hospitals (i.e., Level-III hospital). Antipsychotic use was associated with lower treatment satisfaction while there was no significant difference with respect to physical and mental QOL between the antipsychotic and nonantipsychotic groups.</p><p><b>CONCLUSIONS</b>Concurrent antipsychotic use was found in about one in four treated depressed patients in China, which has increased over a 10-year period. Considering the association of drug-induced side effects and the lack of patients' and relatives' satisfaction with antipsychotic treatment, further examination of the rationale and appropriateness of the use of antipsychotics in depression is needed.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To demonstrate an effective operation of extra-anatomic bypass for complex aortic coarctation in adults.</p><p><b>METHODS</b>Between July 1997 and October 2010, 51 patients underwent extra-anatomic aortic bypass. There were 39 male and 12 female patients. Mean age was (40 ± 14) years (ranging from 18 to 63 years). Operative technique of extra-anatomic bypass consisted of performing an ascending-to-descending or abdominal or femoral aorta bypass (8, 39 and 4 patients). Concomitant procedures were performed in 38 patients: 10 isolated aortic valve replacements (AVR), 11 aortic root replacements (Bentall), 4 ascending aorta replacements including 3 concomitant AVR, 5 mitral valve replacements including 3 concomitant AVR, 4 ventricular septal defect correcting with AVR, and 4 coronary artery bypass graft.</p><p><b>RESULTS</b>Mean follow-up time was (30 ± 9) months (ranging from 5 to 60 months). Two patients were reoperated for hemorrhage in descending aorta anastomosis, one of whom was dead of multiple organ failure in perioperative period. Upper-extremity blood pressure after coarctation correction with extra-anatomic aortic bypass was significantly improved (< 10 mmHg, 1 mmHg = 0.133 kPa). Arterial hypertension was well improved, except 10 patients controlled with less drug therapy. All grafts were patent without obstruction or pseudoaneurysm formation in the follow-up period evaluated by vascular ultrasound and computed tomographic angiogram.</p><p><b>CONCLUSION</b>Extra-anatomic aortic bypass is a safe and effective option for complex aortic coarctation in adults.</p>

ABSTRACT

<p><b>OBJECTIVES</b>To study perioperative inflammatory response status in patients with acute aortic dissection. To analyze the reason and outcome of the inflammatory activation.</p><p><b>METHODS</b>Between August 2011 and December 2011, 30 patients (22 male and 8 female, mean aged (43 ± 9) years) had undergone open repairs of aortic dissection or aneurysm with deep hypothermic circulatory arrest. Indications for surgical intervention were type A aortic dissection in 26 patients and aortic aneurysm in 4 patients. In detail, ascending aorta and arch replacement combined with stent elephant trunk were done in 29 patients, arch replacement combined with stent elephant trunk in 1 patient. According to the time from clinical onset of the dissection to operation, acute group (less than 7 days, group A) 20 patients, chronic group (more than 30 days and aortic aneurysm, group C) 10 patients. White blood cell, C-reactive protein and procalcitonin were assayed before and after operation. These valuables were recorded and compared statistically between two groups.</p><p><b>RESULTS</b>There were no significant differences in age, operation time, and blood transfusion volume (P > 0.05). Preoperative serum level of inflammatory indicators in group A were significant higher than in group C (t > 3, P < 0.05). Postoperative serum peak level of these indicators were significant higher than preoperative level in both groups (t > 4, P < 0.05). There were much more complications occurred on patients in group A (21 cases) than in group C (0 cases). The occurrence of early postoperative complications in group A was much higher than group C (χ(2) = 12.209, P = 0.000). Mechanic ventilation time in group A and group C were (35 ± 58) hours and (18 ± 9) hours respectively. ICU length of stay in two group were (49 ± 61) hours and (33 ± 12) hours, respectively. The patients with mechanic ventilation time more than 24 h, ICU length of stay more than 5 days in group A was more than in group C significantly (χ(2) = 5.161, P = 0.010; χ(2) = 3.657, P = 0.024).</p><p><b>CONCLUSIONS</b>Acute aortic dissection and surgical procedure induce an acute phase inflammatory reaction. The patients with acute aortic dissection involved more serious organic injury and worse outcome following surgery compared with chronic aortic dissection.</p>

ABSTRACT

<p><b>BACKGROUND</b>Pediatric patients are susceptible to lung injury. Acute lung injury in children often results in high mortality. Partial liquid ventilation (PLV) has been shown to markedly improve oxygenation and reduce histologic evidence of injury in a number of lung injury models. This study was designed to examine the hypothesis that PLV would attenuate the production of local and systemic tumor necrosis factor (TNF)-α in an immature piglet model of acute lung injury induced by oleic acid (OA).</p><p><b>METHODS</b>Twelve Chinese immature piglets were induced acute lung injury by OA. The animals were randomly assigned to two groups of six animals, (1) conventional mechanical ventilation (MV) group and (2) PLV with 10 ml/kg FC-77 group.</p><p><b>RESULTS</b>Compared with MV group, the PLV group had better cardiopulmonary variables (P < 0.05). These variables included heart rate, mean blood pressure, blood pH, partial pressure of arterial oxygen (PaO2), PaO2/inspired O2 fraction (FiO2) and partial pressure of arterial carbon dioxide (PaCO2). PLV reduced TNF-α levels both in plasma and tissue compared with MV group (P < 0.05).</p><p><b>CONCLUSION</b>PLV provides protective effects against TNF-α response in OA-induced acute lung injury in immature piglets.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the risk factors of hepatic dysfunction following Stanford A and stanford B aortic dissection repair with deep hypothermic circulatory arrest (DHCA).</p><p><b>METHODS</b>Between January 2006 and June 2008, 208 patients [156 male and 52 female, mean aged (45 ± 11) years] underwent open repairs of aortic dissection with DHCA. Indications for surgical intervention were type A aortic dissection in 181 patients and type B in 27 patients. Acute aortic dissection occurred on 121 patients, chronic aortic dissection occurred on 87 patients. Complications included hypertension, diabetes, cardiac dysfunction, renal dysfunction, and hepatic dysfunction. Twenty-one patients had previous aortic surgery. Data were gathered for multiple preoperative and intraoperative factors including age, gender, diagnosis, aortic dissection type, preoperative ejection fraction, aortic surgery history, surgical intervention type, cardiopulmonary bypass (CPB) time, aortic cross-clamp time, blood transfusion volume (PRBC). Serum glutamic-pyruvic transaminase (GPT), 1-lactate dehydrogenase (LDH) and total bilirubin (TBIL) were assayed before and after operation, as well as 12 h, 1 d, 3 d, 5 d, 7 d. These valuables were recorded and described statistically. All the factors were evaluated by means of univariate and multivariate Logistic analysis to identify relative risk factors of hepatic dysfunction.</p><p><b>RESULTS</b>The CPB time and aortic cross-clamp time were (189 ± 48) min and (93 ± 41) min, respectively. Hepatic dysfunction occurred in 18 (8.7%) patients. Serum GPT and serum LDH elevated significantly within 24 h after aortic surgery, and then went down gradually. Postoperative serum TBIL were much higher than preoperative level on the first day and there was no significant reduction during the following seven days. Preoperative serum creatinine > 133 µmol/L (P < 0.01), preoperative GPT > 40 U/L (P < 0.01), acute aortic dissection (P < 0.05), CPB time > 180 min (P < 0.05), aortic cross-clamp time > 100 min (P = 0.035), PRBC > 10 unit (P < 0.01) were the risk factors for hepatic dysfunction. Furthermore preoperative GPT > 40 U/L (P < 0.01) and PRBC > 10 unit (P < 0.01) were independent determinants for hepatic dysfunction.</p><p><b>CONCLUSIONS</b>Multiple risk factors impact the onset of postoperative hepatic dysfunction. Rather, a combination of factors, especially preoperative hepatic injury, massive blood transfusion produced the highest odds of deficit.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To identify the predictors of prolonged intensive care unit (ICU) stay in patients undergoing aortic arch replacement.</p><p><b>METHODS</b>The clinical data of 173 consecutive patients undergoing aortic arch replacement requiring deep hypothermic circulatory arrest plus antegrade selective cerebral perfusion were reviewed retrospectively. Patients who had undergone one-stage total or subtotal aortic replacement were excluded. Data collected from records were used to identify univariate and multivariate predictors for prolonged ICU stay, which was defined as longer than 5 days in ICU postoperatively.</p><p><b>RESULTS</b>Patients aged (45.4 +/- 10. 6) years and male accounted for 76.3%. The incidence of prolonged ICU stay was 22.0%. The incidences of postoperative stroke and acute renal failure were 6.4% and 4.6%, respectively. The in-hospital mortality rate was 2.9%. Univariate predictors for prolonged ICU stay included body mass index, preoperative serum creatinine level, emergent surgery, coronary artery bypass grafting at the same time, cardiopulmonary bypass time, myocardial ischemic time, and occurrence of postoperative stroke and/or acute renal failure. Multivariable modeling identified that emergent surgery (odds ratio [95% confidence interval] -3.1 [1.3, 7.6]), cardiopulmonary bypass time longer than 180 min (3.3 [1.4, 8.1]), postoperative stroke (6.9 [1.1, 43.1]) and acute renal failure (14.5 [1.3, 161.6]) were the independent predictors for prolonged ICU stay.</p><p><b>CONCLUSIONS</b>The incidence of prolonged ICU stay is high after aortic arch replacement. Patients with identified multivariate predictors carry a higher risk of prolonged ICU stay and may benefit from enhanced perioperative protection of brain and kidney.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To summarize the experience of one-stage total and subtotal aortic replacement for aneurysm evolving the entire aorta and show the midterm results of the operation.</p><p><b>METHODS</b>From February 2004 to July 2008, 22 patients (17 men and 5 women, age ranged from 19 to 47 years old) underwent one-stage total or subtotal aortic replacement under deep hypothermic circulatory arrest and selective antegrade cerebral perfusion. Seven patients received subtotal aortic replacement (from the aortic valve to the abdominal aorta). Fifteen patients underwent total aortic replacement (from the aortic valve to the aortic bifurcation). Patients were opened with a mid-sternotomy and a thoracoabdominal incision. First, the ascending aorta was replaced; following which the aortic arch was reconstructed. Finally, the thoracoabdominal aorta was fully replaced.</p><p><b>RESULTS</b>Thirty-day mortality was 4.5% (1/22). One patient died of multiple organ failure 11 days postoperatively. Two patients had cerebral infarction secondary to embolism. Spinal neurological deficits didn't occur. Twenty-one patients survived the operation and were followed up for 3 to 56 months (35.0 +/- 16.9 months). There was no late death. One patient received aortic valve replacement due to aortic valve regurgitation one year after David and total aortic replacement.</p><p><b>CONCLUSION</b>One-stage total and subtotal aortic replacement is an effective operation for aneurysm evolving the whole length of the aorta with acceptable mortality and morbidity. Midterm follow-up showed satisfactory results.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical efficacy of two brain protective methods for aortic operation according to S100beta protein (S100beta) and interleukin-6 (IL-6) in cerebrospinal fluid (CSF).</p><p><b>METHODS</b>From November 2004 to April 2005, 14 patients who underwent aortic operations with circulatory arrest were alternatively allocated to one of two methods of brain protection: only deep hypothermic circulatory arrest (core temperature, 18 degrees C) for descending thoracic aorta operations (group DHCA, n = 5) or selective antegrade cerebral perfusion (core temperature, 20 degrees C; flow rate, 10 ml kg(-1) min(-1)) for aortic arch operations with DHCA (group ASCP, n = 9). Indications for surgical intervention were Stanford type A dissection in 11 patients, Stanford type B dissection in 2 patients, false aneurysm on thoracoabdominal aorta in 1 patient. S100beta and IL-6 in CSF were assayed in all patients from each group before cardiopulmonary bypass, as well as 0, 6, 12, 24, 48, 72 h after the operation.</p><p><b>RESULTS</b>There were no significant differences in lowest core temperature (P > 0.05), hematocrit in lowest core temperature (P > 0.05) and the velocity of rewarming. Mean circulatory arrest time in ASCP group was significant longer than in DHCA group (P < 0.05). There were much more patients with jugular arteries impaired or accompanied with related cerebrovascular diseases in group ASCP compared to group DHCA. The baseline of S100beta in CSF before cardiopulmonary bypass was no difference. S100beta value in CSF ascended to peak level in 12 h after the operation, showing significantly higher in group DHCA than in group ASCP [DHCA vs. ASCP, (0.90 +/- 0.11) microg/ml vs. (0.61 +/- 0.26) pg/ml]. In most hours after operation there was significant intergroup difference. IL-6 value in CSF ascended to peak level in 12 h postoperative for group DHCA and 0 h postoperative for group ASCP. There was no significance difference observed in IL-6 of CSF between two groups except 6 h and 12 h postoperative.</p><p><b>CONCLUSIONS</b>Brain ischemic injury occurred during aortic operations assisted by brain protective methods is not serious. Unilateral ASCP which can delivery adequate oxygen to brain during circulation arrest has some advantage of alleviating ischemic injury compared with only DHCA.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To summarized the experience of simultaneous aortic operation and coronary artery bypass.</p><p><b>METHODS</b>Between November 1997 and September 2004, thirty-six patients who underwent combined aortic operation and coronary artery bypass graft (CABG) were reviewed with a mean age of (57 +/- 12) years (range 31 to 75). Nineteen patients were suffered from aortic dissection. There were 17 patients of aortic aneurysm, 5 aortic root aneurysm, 5 ascending aortic aneurysm, 4 aortic arch aneurysm, 3 abdominal aneurysm. Preoperational coronary angiography was performed in 1 of 10 acute type A dissection patients. The coronary arteries were involved by dissection in 7 acute type A dissection patients. The artherosclerosis of coronary artery was found during operation in 2 patients. Among 7 patients with chronic type A aortic dissection, coronary angiography was performed in 2, coronary artery was involved by dissection in 2 and coronary arterosclaerosis was founded in 3. There were 2 patients with acute or chronic type B aortic dissection. The stenosis of coronary artery was confirmed by preoperative angiography in the patients with aortic aneurysm. There were 57 coronary bypass grafts, 6 of them were artery grafts, and others were venous grafts.</p><p><b>RESULTS</b>The mean cardiopulmonary bypass time was (157 +/- 54) min, and the mean aortic cross clamp time was (98 +/- 31) min. Five patients with type A aortic dissection died postoperatively, 3 from heart failure leading to multi organ system failure, 1 from cerebral hernia and one from ischemia of intestinal tract. Postoperative complication included reoperation for hemorrhage in 1 patient, respiratory failure in 1 patient.</p><p><b>CONCLUSIONS</b>Type A aortic dissection with coronary involvement or arterosclaerosis is associated with high mortality rate. Coronary artery angiography should be performed in the elder than 50 years patient with aortic aneurysm. Combined aortic aneurysm operation and CABG is a safe procedure.</p>

ABSTRACT

<p><b>OBJECTIVE</b>The purpose of this study was to explore the association of gender and age on in-hospital mortality after coronary artery bypass graft (CABG) among the Chinese population.</p><p><b>METHODS</b>A total of 2682 patients (male: 2316, female: 366) who underwent CABG surgery were retrospectively investigated between January 1st, 1997 and December 31st, 2001 for perioperative risk factors and in-hospital mortality rate after CABG.</p><p><b>RESULTS</b>Preoperative comorbidity rate and postoperative complication rate were higher in women than that in men, although left ventricular ejection fraction was higher and the number of diseased vessels fewer in women than in men. The in-hospital mortality rate was three times higher in women than that in men (3.01% vs. 1.12%, P = 0.001), especially in the younger age group (2.6% vs. 0.5%, P = 0.001, risk-adjusted odds ratio 4.844, 95% CI: 1.549 - 15.142). In older patients, there was no notable difference in in-hospital mortality between the genders (3.7% for women vs. 2.4% for men, P = 0.383).</p><p><b>CONCLUSIONS</b>Chinese woman, especially in younger age, had a higher in-hospital mortality rate post CABG than that in men, suggesting that younger female gender is an independent risk factor for in-hospital mortality after CABG. Future studies are warranted to clarify the underlying mechanisms.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate effectiveness of surgical correction in patients with anomalous origin of the coronary artery from the pulmonary artery.</p><p><b>METHODS</b>Between April 1999 and August 2005, 12 patients with anomalous origin of the coronary artery from the pulmonary artery underwent surgical correction. There were 8 patients with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), and 4 patients with anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA). Eight patients underwent direct aortic reimplantation, and 4 patients underwent a Takeuchi procedure (intrapulmonary artery baffle with an autologous pericardial patch). Simultaneous mitral annuloplasty was performed in 7 patients of ALCAPA with moderate and severe mitral regurgitation. One patient of ARCAPA was associated with an atrial septal defect (ASD) which was closed with an amplatzer septal occluder through right atrium under transesophageal echocardiography (TEE) without CPB.</p><p><b>RESULTS</b>There were neither early and late deaths nor postoperative complications. Follow-up of all patients ranged from 7 to 83 months (mean, 32 +/- 24 months). The left ventricular function after operation improved from a preoperative fractional shortening (FS) of 0.21 +/- 0.09 to 0.35 +/- 0.06 (P = 0.006) for patients with ALCAPA. Preoperative mitral regurgitation decreased in 7 patients of ALCAPA after mitral annuloplasty at the follow-up. All patients were doing well and their exercise tolerance improved to normal. They were free from symptoms.</p><p><b>CONCLUSIONS</b>Reestablishment of a two-coronary system is necessary for patients with anomalous origin of the coronary artery from the pulmonary artery. The left ventricular function improved after 2-coronary repair. We recommend that the simultaneous mitral annuloplasty should be performed at the time of operation for patients who have moderate and severe mitral regurgitation with ALCAPA. Surgical correction of ARCAPA and ARCAPA show good early and mid-term results, long-term results need to be followed up.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To discuss the clinical features and surgical treatments of giant coronary artery aneurysm (CAA).</p><p><b>METHODS</b>From July 1996 to October 2004, 6 giant CAA patients were underwent surgery at Fuwai hospital. Three cases were underwent CAA resection, 2 concomitant coronary bypass, 3 reconstruction. The giant CAA was often combined with other cardiac diseases. Four cases underwent additional procedures of fistula closure, 3 aortic valve replacements, 2 aortoplasty and 1 thrombus cleaning at the same time.</p><p><b>RESULTS</b>All patients recovered uneventfully. The mean of cardiopulmonary bypass time was (144 +/- 26) min (range 67 to 207 min). Aortic cross clamping time was (104 +/- 21) min (range 56 to 172 min). Patients follow-up time occurred from 8 to 87 months (mean of 48 months). All patients were free of symptoms during follow-up. None of the patients died during the follow-up period and none of the CAA recurred.</p><p><b>CONCLUSIONS</b>The giant CAA is a serious cardiovascular disease, early diagnosis and surgical treatment are mandatory.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To summarize operational effect with surgical treatment of aortic regurgitation caused by Behcet's disease and discuss relevant surgical techniques for treatment of these conditions.</p><p><b>METHODS</b>Eight patients with aortic regurgitation secondary to Behcet's disease and received surgery between April 1997 and August 2003 were retrospetively analyzed. Among them, two patients had their aortic valves replaced in other hospital before admitted to our hospital where one undertook aortic valve replacement (AVR), and the other undertook aortic root replacement (ARR). In six patients who were initially treated in our hospital, the surgical procedures for aortic regurgitation included AVR in three patients and ARR operation in other three patients in whom Bentall-type operation was conducted in two patients and Cabrol-type operation in one.</p><p><b>RESULTS</b>One patient died during hospital stay. The follow-up periods ranged from 3 months to 36 months. In five patients with prosthetic valve detachment or suture detachment, redo homograft replacement was required in one patient and redo AVR in 3, one patient had redo AVR twice, and the remaining one patient had no surgery at present. Three patients primarily operated by ARR operation have no complications.</p><p><b>CONCLUSIONS</b>The rate of prosthetic valve detachment is high in patients with Behcet's disease. ARR should be a first-line therapy for operation promised these patients.</p>
