The incidence of acute myocardial infarction (AMI) is increasing. Acute papillary muscle rupture is one of the serious and rare mechanical complications of AMI, which occurs mostly in inferior and posterior myocardial infarction. A patient with acute inferior myocardial infarction developed pulmonary edema and refractory shock, followed by cardiac arrest. After cardiopulmonary resuscitation (CPR), revascularization of criminal vessels was carried out by emergency percutaneous transluminal coronary angioplasty (PTCA) under the support of intra-aortic balloon pump (IABP) and extra corporeal membrane oxygenation (ECMO). Although the patient was given a chance for surgery, his family gave up treatment due to unsuccessful brain resuscitation. It reminds that mechanical complications such as acute papillary muscle rupture, valvular dysfunction and rupture of the heart should be highly suspected when cardiogenic pulmonary edema and cardiogenic shock are difficult to correct in acute inferior myocardial infarction. Echocardiogram and surgery should be put forward when revascularization of criminal vessels is available.

OBJECTIVETo investigate the chronic effects of intracoronary autologous bone marrow mononuclear cell (BM-MNCs) transplantation in patients with refractory heart failure (RIHF) after myocardial infarction.

METHODSThirty patients with RIHF (LVEF < 40%) were enrolled in this nonrandomized study, autologous BM-MNCs (5.0 +/- 0.7) x 10(7) were transplanted with via infarct-related coronary artery in 16 patients and 14 patients received standard medical therapy served as control. Baseline and follow up evaluations included complete clinical evaluations, plasma BNP, ANP, ET-1 measurements, echocardiography, PET, and Holter monitoring.

RESULTSBaseline characteristics were similar between the 2 groups. There were no major periprocedural complications. One patient developed ventricular premature contractions during cell infusion for several seconds and recovered spontaneously. Compared to pre-transplantation, plasma BNP and ET-1 significantly decreased and plasma ANP significantly increased at 7 days post transplantation; 6 minutes walking distance increased from (72.1 +/- 31.5) to (201.6 +/- 23.3) m (P < 0.01), LVEF increased 9.9% (P < 0.001) and FDG-PET revealed vital myocardium area increased (10.3 +/- 3.4)% (P < 0.01) at 3 months after BM-MNCs transplantation. At 6 months follow up, the NYHA class improved from (3.4 +/- 0.1 to 2.4 +/- 0.2, P < 0.001) and no patient died and 1 patient rehospitalized due to lower extremities edema. In control group, LVEF decreased 7.2% compared to baseline (P < 0.001) and was significantly lower than transplantation group at 3 months (P < 0.001). At 6 months follow up, the NYHA class increased from (3.5 +/- 0.1 to 3.9 +/- 0.1, P < 0.05), 2 patients died and 10 patients rehospitalized due to aggravated heart failure.

CONCLUSIONPresent study demonstrates that intracoronary transplantation of autologous BM-MNCs is safe and effective for treating patients with RIHF after myocardial infarction.

Objective: To evaluate the acute and long-term outcome of patients with ST segment elevation myocardial infarction (STEMI) concurrent with chronic total occlusion (CTO) undergoing primary percutaneous coronary intervention (PCI). Methods: 11 905 STEMI patients from the China Acute Myocardial Infarction Registry were enrolled in this study and divided into CTO group and non-CTO group according to the angiography results of primary PCI. 1∶3 propensity score matching was used to match the patients between the two groups. The primary endpoint was in-hospital mortality and mortality at 1-year post PCI. The secondary endpoint was major adverse cardiovascular events (MACE) including death, re-myocardial infarction, revascularization, heart failure associated readmission, stroke and major bleeding at 1-year post PCI. Results: There were 931 CTO patients (7.8%) in this cohort (male=755 (81.1%), mean age (62.2±11.4 years)). The rest 10 974 patients were STEMI without CTO (male=8 829 (80.5%),mean age (60.0±11.8) years). After propensity score matching, 896 patients were enrolled in CTO group and 2 688 in non-CTO group. In-hospital mortality was significantly higher in the CTO group than in non-CTO group (4.2% vs. 2.4%, P=0.006). The ratio of all cause death, cardiac death, and MACE at 1-year follow up was also significantly higher in the CTO group than in non-CTO group (8.5% vs. 4.4%, P<0.001, 5.3% vs. 2.6%, P=0.001, 35.1% vs. 23.3%, P<0.001, respectively). Multiple regression analysis showed that CTO (HR=1.54, 95%CI 1.06-2.22, P=0.022), advanced age (HR=1.06, 95%CI 1.04-1.08, P<0.001), and previous heart failure history (HR=4.10, 95%CI 1.90-8.83, P<0.001) were independent risk factors of 1-year mortality. Conclusions: The in-hospital and 1-year mortality increased significantly in STEMI patients concurrent with CTO. CTO, advanced age and history of heart failure are independent risk factors of 1-year death among STEMI patients.

BACKGROUNDThe most appropriate surgical approach for patients with post-infarction left ventricular (LV) aneurysm remains undetermined. We compared the efficacy of the linear versus patch repair techniques, and investigated the mid-term changes of LV geometry and cardiac function, for repair of LV aneurysms.

METHODSWe reviewed the records of 194 patients who had surgery for a post-infarction LV aneurysm between 1998 and 2010. Short-term and mid-term outcomes, including complications, cardiac function and mortality, were assessed. LV end-diastolic and systolic dimensions (LVEDD and LVESD), LV end-diastolic and end-systolic volume indexes (LVEDVI and LVESVI) and LV ejection fraction (LVEF) were measured on pre-operative and follow-up echocardiography.

RESULTSOverall in-hospital mortality was 4.12%, and major morbidity showed no significant differences between the two groups. Multivariate analysis identified preoperative left ventricular end diastolic pressure > 20 mmHg, low cardiac output and aortic clamping time > 2 hours as risk factors for early mortality. Follow-up revealed that LVEF improved from 37% pre-operation to 45% 12 months post-operation in the patch group (P = 0.008), and from 44% pre-operation to 40% 12 months postoperation in the linear group (P = 0.032). In contrast, the LVEDVI and LVESVI in the linear group were significantly reduced immediately after the operation, and increased again at follow-up. However, in the patch group, the LVEDVI and LVESVI were significantly reduced at follow-up. And there were significant differences in the correct value changes of LVEF and left ventricular remodeling between linear repair and patch groups.

CONCLUSIONSPersistent reduction of LV dimensions after the patch repair procedure seems to be a procedure-related problem. The choice of the technique should be tailored on an individual basis and surgeon's preference. The patch remodeling technique results in a better LVEF improvement, further significant reductions in LV dimensions and volumes than does the linear repair technique. The results suggest that LV patch remodeling is a better surgical choice for patients with post-infarction LV aneurysm.

INTRODUCTIONAtherosclerotic coronary artery thrombosis is the most common cause of acute myocardial infarction.

CLINICAL PICTUREA 30-year-old lady presented with acute peripartum massive anterior ST segment myocardial infarction and cardiogenic shock. This was due to acute Stanford type A aortic dissection with the intimal flap occluding the left coronary ostium. The initial diagnosis was not apparent. Echocardiography confirmed the diagnosis.

TREATMENT AND OUTCOMEShe underwent emergency surgical repair (Bentall procedure). Pathology confirmed underlying idiopathic cystic medial degeneration.

CONCLUSIONA high index of clinical suspicion is required in acute myocardial infarction presenting without traditional cardiovascular risk factors.

OBJECTIVETo explore the way of promoting the efficacy of surgical treatment for ventricular septal rupture (VSR) after acute myocardium infarction in terms of perioperative and long term survival.

METHODSThe clinic data of 37 VSR cases underwent surgical treatment from October 1994 to October 2007 were analyzed retrospectively. There were 24 male and 13 female, and the age was (63.4 +/- 7.6) years old. The whole group was divided into the VSR repair plus revascularization group (group A, 26 cases) and simple VSR repair group (group B, 11 cases).

RESULTSThere were 4 operative deaths in group A (15.4%), 7 deaths in group B (63.6%), P = 0.006. With the follow-up of (34.0 +/- 29.8) months ranged from 2 to 103 months of the 26 operational survivors, there were 5 late deaths, of which 2 deaths in group A and 3 deaths in group B. According to the Kaplan-Meier survival curve, the actuarial survival rate at 6 to 8 year was (64.3 +/- 21.0)% for group A and the actuarial survival rate at 4 year was (25.0 +/- 21.7)% for group B, P = 0.011. Of the 21 mid-long term survivors, 17 cases were in NYHA class I to II and 4 cases in NYHA class III to IV. There were 4 cases suffered from VSR recurrence. According to Logistic regression, the risk factors for the early death were not adoptive of revascularization, cardiogenic shock and emergency surgical procedure, while the risk factors for late death were not adoptive of revascularization and low cardiac output after the procedures.

CONCLUSIONSVSR repair plus revascularization could improve the perioperative and mid-long term survival for the surgical treatment of VSR. The appropriate timing and procedures of the surgical operation are very important to promote perioperative survival and to prevent VSR recurrence.

OBJECTIVE: To analyses the causes and prevention of systemic complications of functional endoscopic sinus surgery (FESS) in patients with chronic rhinosinusitis. METHOD: Three typical cases were reported including their medical history, preoperative diagnosis, medications during preoperational period, complications and treatment. The causes and preventive measures of systemic complications were analyzed. RESULT: Three patients were all suffered from chronic rhinosinusitis with nasal polyps (CRSwNP). After FESS, 1 case was complicated with coma and hyponatremia, 1 case with acute myocardial infarction, and 1 case with lower extremity deep venous thrombosis. The patient with coma and hyponatremia was soon waked after intravenous infusion of 10% sodium chloride. Two patients with acute myocardial infarction and lower extremity deep venous thrombosis were soon completely rehabilitated after emergency thrombolytic therapy and endovascular intervention. Three patients were completed recovered from their systemic complications without any severe sequela. CONCLUSION Systemic hemostatic drugs should be banned in patients with hypercoagulable state in perioperation period of FESS in order to avoid severe systemic complications. Timely vascular interventional treatment can prevent severe sequels.

This report describes the case of a 45-year-old Korean female who had suffered from Behcet's syndrome for two years with a huge, unruptured aneurysm originating from the left coronary sinus. The aneurysm had caused myocardial and aortic insufficiency by compressing the proximal left anterior descending coronary artery. The orifice of the aneurysm was at the left coronary sinus, about 5mm from the left main coronary ostium, and it was filled with organized thrombi. Surgical repair was performed by closing the entrance of the aneurysm with a Dacron patch and by implementing aortic valve repair and coronary artery bypass grafting. The patient's coronary flow was restored postoperatively, and all anginal symptoms disappeared.
