Background: Left ventricular rupture after acute myocardial infarction is a serious complication with high mortality. Emergency operation is usually the only available treatment. A 76-year-old female with persistent chest pain and syncopal attacks was admitted. Transthoracic echocardiography showed the pericardial effusion and generalized hypokinesia of the inferolateral wall of left ventricle. Coronary angiography revealed a total occlusion of the first diagonal branch. After percutaneous transluminal coronary angioplasty with coronary stent and insertion of intraaortic balloon pump, emergency operation was performed. Under cardiopulmonary bypass and cardiac arrest with cold blood cardioplegia, coronary artery bypass graft with saphenous vein, pericardial patch covering on the rupture area with 6-0 polypropylene running sutures, and fibrin glue compression under the patch were performed. We present a case of left ventricular (free wall) rupture after acute myocardial infarction.

Despite early aggressive treatment, post myocardial infarction(MI) ventricular septal defect(VSD) revealed high surgical mortality. We reviewed the 10-year experiences of surgically treated post-MI VSD in Yonsei University. Material and Method: From Jan. 1991 to May 2001, 17 patients underwent surgical repair of post-MI VSD. Ages ranged between 47 and 77 years(mean age＝63.2$\pm$9.1). There were 10 males and 7 females. VSD was located at anterior in 16 patients and at posterior in one. IABP was inserted preoperatively in 12 patients due to cardiogenic shock. Mean interval from MI to occurrence of VSD was 5.6 days. Among patients undergoing early surgical correction(n＝13), mean interval from occurrence of VSD to operation was 2.5 days. In 11 patients, concomitant CABG was performed during repair of VSD. Result: Four patients died within 30 days after the operation(30 day mortality＝23.5%). Among 12 patients with preoperative cardiogenic shock, 4 patients died within 30 days(30-day mortality＝33.3%). During mean follow up period of 52 months, one patient died of unknown cause and 10-year survival of discharged patients was 66.7%. All follow-up patients were in NYHA functional class I or II when their last OPD visit. Conclusion: In the treatment of post-MI VSD, aggressive medical treatment with early surgical correction seems to be very important in terms early and long-term survival of patients.

The mortality of left ventricular free wall rupture after acute myocardial infarction is high; however, subactue myocardial rupture can be diagnosed by echocardiogram and the use of the intraaortic balloon pump reduces the incidence of re-rupture. Bleeding from subacute myocardial rupture can be managed by employing fibrin glue and several patches. We report here on a case of successfully managed case of subactue left ventricular free wall rupture after acute myocardial infarction with using the sutureless technique and fibrin glue.

Background/Aims: The impact of left ventricular (LV) diastolic function and filling pressure on clinical outcomes in young patients with acute myocardial infarction (AMI) has been poorly studied. Therefore, the aim of this study was to investigate the impact of LV diastolic function and LV filling pressure on major adverse cardiac events (MACEs) in young patients with AMI. Methods: A total of 200 young patients (males < 45 year, females < 55 year) with AMI were divided into two groups according to the diastolic function; normal (n = 46, $39.5{\pm}5.3$ years) versus abnormal (n = 154, $43.5{\pm}5.1$ years). Results: Despite regional wall motion abnormalities, normal LV diastolic function was not uncommon in young AMI patients (23.0%). During the 40 months of clinical follow-up, MACEs developed in 26 patients (13.0%); 14 re-percutaneous coronary intervention (7.0%), 8 recurrent MI (4.0%), and 4 deaths (2.0%). MACEs did not differ between the normal and abnormal diastolic function group (13.6% vs. 10.9%, p = 0.810), but MACEs were significantly higher in the high LV filling pressure group than the normal LV filling pressure group (36.8% vs. 10.5%, p < 0.001). On multivariate analysis, high LV filling pressure was an independent predictor of MACEs (hazard ratio 3.022, 95% confidence interval 1.200-7.612, p = 0.019). Conclusions: This study suggested that measurement of the LV filling pressure (E/e' ratio) would be useful in the risk stratification of young patients with AMI. However, it would be necessary to monitor this category of patient more carefully.

Here we report a case of posterior left ventricular (LV) free wall rupture following postinfarct ventricular septal rupture (VSR). A 58-year-old man was transferred to the hospital under the impression of acute myocardial infarction. Posterior VSR was seen on echocardiographic examination. The intraaortic balloon pump catheter was introduced percutaneously and the emergent operation was proposed. Sudden circulatory collapse was developed shortly after the anesthetic induction and the patient's chest was hurriedly opened while on cardiopulmonary resuscitation. The acute cardiac tamponade was seen and the blood was seen pumping from the longitudinal tear at the mid-level of LV posterior wall, measuring 2 cm in length. The cardiopulmonary bypass was set and LV reconstruction was done. The postoperative recovery was delayed due to the brain injury presumably caused by preoperative cardiac arrest.

This study aims to design a Severity-Adjusted LOS(Length of Stay) Model in order to efficiently manage LOS of AMI(Acute Myocardial Infarction) patients. We designed a Severity-Adjusted LOS Model with using data-mining methods(multiple regression analysis, decision trees, and neural network) which covered 6,074 AMI patients who showed the diagnosis of I21 from 2004-2009 Korean National Hospital Discharge in-depth Injury Survey. A decision tree model was chosen for the final model that produced superior results. This study discovered that the execution of CABG, status at discharge(alive or dead), comorbidity index, etc. were major factors affecting a Sevirity-Adjustment of LOS of AMI patients. The difference between real LOS and adjusted LOS resulted from hospital location and bed size. The efficient management of LOS of AMI patients requires that we need to perform various activities after identifying differentiating factors. These factors can be specified by applying each hospital's data into this newly designed Severity-Adjusted LOS Model.
