[Emergency surgery of acute coronary insufficiency].

In our centre, during the last five years, emergency operations (within 6 hours) and urgent operations (within 72 hours) have represented 1/4 of all coronary surgery. 295 patients (pts) have been operated on since 1972: of these, 279 with simple revascularization, 5 with combined major surgery, and 11 as a consequence of mechanical complications of acute myocardial infarction. These last were all in cardiogenic shock: the overall 30-day mortality rate was 5.4% (3.6% in those pts with simple revascularization, 20% in those with combined major surgery, and 45.4% in pts with cardiogenic shock). In the subgroup with simple revascularization, the incidence of non fatal perioperative acute myocardial infarction (AMI) was 4.7% in 253 pts with unstable angina, 52.2% in 23 pts with abrupt closure during coronary angioplasty, and obviously 100% in 3 pts surgically treated during evolving AMI. We were able to identify in the univariate analysis as the only 30-day risk mortality factors: 1) a reduced ejection fraction (< 30%) and 2) the combination with endarterectomy. Other factors (female sex, age > 70, severity of angina, diffuse coronary artery disease and more than 3 by pass grafts) have shown a tendency to increase the mortality rate without statistical significance. No deaths occurred in pts revascularized in emergency situations due to coronary angioplasty complications. In recent years emergency and urgent coronary surgical operations have been increasing, with an increase in pts with higher risk factors. In pts with simple revascularization, 30-day mortality and incidence of myocardial infarction are similar to those of elective surgery. In pts with abrupt closure as a consequence of coronary angioplasty the mortality rate seems very low, while the incidence of infarction remains extremely high. These observations have allowed the development of an integrated protocol of intervention in acute unstable coronary syndromes.

[Interventricular rupture following myocardial infarction. Surgical treatment and long-term follow-up].

The natural course of post myocardial infarction ventricular septal defect is towards cardiogenic shock and death. 50% in the first week, over 90% a year latter. Between 1973-1989, 28 patients where operated on. Before surgery 14 patients (53%) where in Killip IV, 5 patients (19%) in III, 5 patients (19%) in II and 2 patients in I. The repair was accomplished under hypothermia and cardioplegia, with the insertion of a Teflon patch to close the defect in 20 patients (70%). Complementary procedures (CABG, Pacemaker, repair of dissections) were performed in 12 patients (47%). Three patients (10%) could not be weaned from the pump; another 10 (36%) died before discharge: 2 with multisystem failure and sepsis, the other 8 with cardiogenic shock (4 with residual VSD). The only independent predictor of operative mortality, by univariate analysis, was preoperatory cardiogenic shock. All 15 survivors (100%) where followed between 5 months and 14.5 years (mean 104.5 months). Two patients died at 4 years, one at 10, another at 10.5 years. The actuarial probability of being alive after discharge was 100% at 4 years, 75% at 5, and 50% at 10 years. At last follow up only 2 patients had mild dyspnea, the remaining where asymptomatic. Surgical treatment provides an opportunity to improve this otherwise dismal survival and offers a surprising good long term result. An early diagnosis and efficient repair, before the onset of cardiogenic shock, should provide better results.

[A case report of oozing type cardiac rupture following acute myocardial infarction: hemostasis with fibrin glue and oxycellulose].

A 65-year-old man was admitted due to acute anterior myocardial infarction. After admission, he fell into cardiac shock. Echocardiogram showed cardiac tamponade due to cardiac rupture. He was immediately transferred to the operating room. After opening the pericardium, 300 ml of bloody pericardial fluid containing coagula was excluded. Hematoma-like infarcted lesion was found on the surface of the left ventricular apex. Because there was no bleeding point, fibrin glue and oxycellulose was fixed on this lesion for pressure hemostasis without any suture. The postoperative course was uneventful.

[Does reperfusion modify the risk of heart rupture? Effects of early reperfusion].

The goal of this study was to evaluate whether early fibrinolytic therapy could reduce in-hospital mortality caused by cardiac rupture in patients with acute myocardial infarction (AMI). Based on the strong correlation between occurrence of left ventricular free wall rupture and development of sudden electromechanical dissociation (EMD) in patients with a first TAMI without relevant heart failure, we compare the incidence of this mechanism of death in patients treated with streptokinase and in those from a control group. The study included 406 patients with a first transmural AMI younger than 71 years who received intravenous streptokinase (SK) with 104 similar patients not treated with fibrinolytic agents. Mortality rate in patients treated with SK was 6% compared to 11% in those from the control group. Patients treated with SK presented a lower incidence of EMD than those from the control group (17% vs 72%; p < 0.002). A necropsy study carried out in 33% of cases, confirmed the existence of left ventricular free wall rupture in each of the 7 cases who presented EMD but in none of the 6 who died in shock. We conclude that left ventricular free wall rupture is the principal cause of mortality in patients admitted to a Coronary Care Unit with a first transmural AMI, and that fibrinolytic treatment reduces mortality mainly by reducing development of cardiac rupture.

[Clinical case and review of the subject. Prognosis in acute myocardial infarction].

Aiming to discuss the value of the prognostic indices in the acute myocardial infarction (AMI), we present two cases of AMI, where the predictable prognosis at 48 hours of the onset of symptoms is informed by the outcome of each case. In the first one, a patient in cardiogenic shock had a good evolution because he suffered a biventricular infarction that responsed well to hydric overcharge. The other case, a Killip classe I infarction, was complicated by a late left ventricular free wall rupture. We discuss the several aspects of each case, and finally we do a critical aproach of the most common prognostic indices (Killip and Kimbal classes, Peel prognostic groups and Norris prognostic groups).

Transcatheter closure of ventricular septal defect: a nonsurgical approach to the care of the patient with acute ventricular septal rupture.

Acute ventricular septal rupture is a potentially fatal complication of myocardial infarction. In the past, surgical repair was the only treatment option for this life-threatening event. However, not all patients are good surgical candidates. Transcatheter closure of a ventricular septal defect (VSD) with a prosthesis called the Rashkind Patent Ductus Arteriosis Occluder System allows closure of the VSD without the possible complications associated with open-heart surgery. This treatment has potential as a temporary measure for patients awaiting surgical repair of VSD. Transcatheter closure may also be used as a permanent treatment for those patients considered to be poor surgical candidates. This case presentation addresses the use of a state-of-the-art nonsurgical approach to VSD closure. The focus is on the unique medical and nursing interventions used in caring for the patient suffering from a myocardial infarction complicated with postinfarction ventricular septal defect.

Postinfarction cardiac rupture in the nineties: do we know determinating factors?

Postinfarction cardiac rupture (PCR) up to the present accounts for approximately 20 percent of autopsy infarcted cases, ranking only behind arrhythmias and cardiac failure in the frequency of AMI complications. We re-examined our observations of a previous anatomo-clinical study of 96 patients who underwent autopsy after death from AMI. Sixteen patients had rupture of the free wall of the left ventricle at the site of infarction. All the patients with rupture showed the following statistically significant characteristics (p less than 0.01) if compared to those without rupture: cardiac hypertrophy (heart weight 390 to 1020 gm; mean: 627.5 +/- 201 gm; left ventricular wall thickness 18 mm to 29 mm; mean: 25.17 +/- 3.6 mm), sudden death (6 cases) without premonitory symptoms or with symptoms of less than an hour's duration or reappearance of chest pain not improved by opiates before late death, that occurred 240 to 660 minutes from chest pain, recorded electrocardiograms showing sinus rhythm with unchanged ST-segment (12 cases), atrioventricular block (2 cases) and junctional rhythm (2 cases). Hypertension pre-existing to the infarction was seen in 6 cases with rupture versus 9 cases without rupture (p less than 0.01). Blood pressure, heart weight and wall thickness of the left ventricle are the most increased parameters in the patients with PCR. Preventive measures against these factors can reduce PCR.

[Cardiac rupture and tamponade in a pregnant woman with acute myocardial infarction].

A case is described of a 35-year old pregnant woman (38-th week, tertigravida) with an acute myocardial infarction (AMI). The diagnosis of anterolateral myocardial infarction was based on the clinical, biochemical, ecg and echocardiographical findings. Ventricular premature beats were observed in the tenth day of AMI: Delivery was accomplished by cesarean section without complications. In the second day after the cesarean section the patient died. On autopsy cardiac rupture, tamponade and fresh necrosis of the lateral wall was found.

Apparent rupture of the ventricular septum after myocardial infarction in an infant with congenital heart disease.

Clinical and angiocardiographic simulation of rupture of the interventricular septum, in an infant with an endocardial cushion defect and documented myocardial infarction is reported. Close straddling of a proven congenital muscular apical ventricular septal defect by trabeculae carne is believed to have led to the angiocardiographic simulation of a post-infarction apical ventricular septal defect. In the surgical approach to post-infarction ventricular septal defects, the implication of such a simulation could be important.

[False aneurysm associated with mitral insufficiency due to rupture of the heart at the point of insertion of the anterior papillary muscle. A successfully operated case].

Although rupture of a mitral papillary muscle during myocardial infarction is well known, and post-infarction transmural ruptures causing false aneurysms occasionally reported, the association of rupture of the anterior papillary muscle and a underlying transmural parietal rupture giving rise to a false aneurysm is quite exceptional, and, to the best of our knowledge, has not previously been reported. Despite the serious nature of the disease, surgical cure of the aneurysm with mitral valve replacement was successful, due to the limitation of the anatomical disruption by early pericardial symphysis.

Post-infarction cardiac rupture.

Three allied conditions are described in this paper: (i) haemopericardium with cardiac rupture (5 cases); (ii) haemopericardium without rupture (2 cases); (iii) pseudoaneurysm (1 case). In the first 2 of these, the significant features were clinical deterioration with shock 3 or more days after infarction, recurrent cardiac pain, cardiac tamponade, and immediate or later ineffectiveness of counterpulsation. An additional feature in the second group was the development of haemopericardium after heparin therapy. In the third group, infarction followed by left ventricular failure and progressive cardiac enlargement was the significant feature. An apical systolic murmur was not present, as a false sac had not been formed. Ante-mortem diagnosis depends upon an appreciation of these features. Without it successful surgery is impossible. There were 4 survivors in this group of 8 patients.
