[Post infarction ventricular septal defect. Echocardiographic analysis of patients treated with positive end-expiratory pressure].

Interventricular septal rupture is a life-threatening complication occurring in 0.5 to 1.0% of patients following acute myocardial infarction and often results in right and left ventricular failure. This study aimed at evaluating the echocardiographic effects of PEEP on right (RV) and left (LV) ventricular dimension in three patients who developed a postinfarction septal defect and in whom acute respiratory failure was a preterminal event. The effects of PEPP on the heart remain controversial. We observed in all three patients a sudden large increase in RV dimensions and hence, probably through ventricular interdependence, a proportional decrease in LV dimensions. The progressive leftward septal displacement with increasing levels of PEEP probably contributed to reduce LV compliance. We concluded that PEEP therapy in this group of patients had no proven beneficial effects and probably contributed to further RV dilatation and failure.

Fibrin sealant for early repair of acquired ventricular septal defect.

The trend toward early operation for acquired ventricular septal defects exposes the patient to major perioperative bleeding and residual shunt because of the fragility of the recently necrosed myocardium. To reduce these complications we have used a fibrin sealant to reinforce the cardiac tissues in addition to the usual closure of the defect with a Dacron patch through a left ventricular septum around the defect, area. During cardiac arrest fibrin sealant is applied on the ventricular septum around the defect, between the septum and the patch, and on the edges of the ventriculotomy. This technique was used in three patients (mean age 68.2 years) operated on for an acquired ventricular septal defect within 4 days of the infarction and within 24 hours of the occurrence of the defect. Low postoperative bleeding, absence of recurrent shunt, and good ventricular function indicated satisfactory surgical result in all three patients. We suggest that the use of fibrin sealant during operations for acquired ventricular septal defects, by reinforcing the necrotic and fragile tissues, may reduce perioperative bleeding and assure a more solid implantation of the patch.

[Surgical treatment of secondary complications of myocardial infarction].

The results are presented od surgical treatment of 18 patients operated on in the Cardiosurgery Department, Institute of Cardiology, Medical Academy in Lódź, in the years 1985-1989, for complications of myocardial infarction. The material includes such complications as: post-infarction perforation of the septum, and post-infarction aneurysm of the left ventricle. The usefulness of specialized examinations is shown in qualifying the patients for operation, and the method is presented of carrying out operations in these patients in extracorporeal circulation. Good results of surgical treatment were achieved.

Left ventricular free-wall rupture occurring during programmed ventricular stimulation in a patient with recent myocardial infarction.

In this report we describe a patient who died during programmed ventricular stimulation due to a rupture of the left ventricular free wall at the site of a recent myocardial infarction. The patient was a 75-year-old male who presented with an extensive anterior wall myocardial infarction complicated by sustained ventricular tachycardia occurring 8 days after admission. Cardiac catheterization revealed total occlusion of left anterior descending coronary artery and an anteroapical aneurysm. The patient died due to electromechanical dissociation during electrophysiological testing 11 days after myocardial infarction. Postmortem examination showed a rupture of the left ventricular free wall at the site of the myocardial infarction and distant from the site of catheter placement. It is suggested that caution be taken in choosing patients for electrophysiological studies who have had recent large myocardial infarctions with ventricular aneurysm.

Technical improvements in the repair of acute postinfarction ventricular septal rupture.

Postinfarction ventricular septal rupture (VSR) is a high-risk complication following myocardial infarction (MI). Surgical treatment has evolved to improve an otherwise poor prognosis. Certain subsets of patients remain a formidable challenge. The presence of cardiogenic shock has consistently been found to have the highest risk. Over a 10-year period, our technique of repair has evolved from established procedures to one we believe confers superior results. Endocardial patching to viable myocardium reinforced with an epicardial patch not only corrects the shunt but maintains ventricular geometry and avoids tension on friable muscle. We report on a series of nine consecutive patients in cardiogenic shock. The operative mortality was 22%, none due to low cardiac output syndrome, shunt recurrence, or bleeding. All patients have been followed with transesophageal echocardiography at a mean period of 14 months (range 3-31 months). One patient is in New York Heart Association (NYHA) Class I, four are in NYHA Class II, and two in NYHA Class III.

Cardiac rupture after thrombolytic therapy: the use of aprotinin to reduce blood loss after surgical repair.

Emergency cardiac surgery after recent thrombolytic therapy is associated with increased blood loss. A patient underwent emergency repair of a ruptured left ventricle after intravenous streptokinase treatment for acute coronary occlusion. High dose aprotinin was given during the operation to reduce the expected blood loss. Surgical repair was successful without bleeding complications. Total postoperative blood loss was 365 ml.

[Doppler echocardiography in the diagnosis of mechanic complications of acute myocardial infarction].

OBJECTIVES: To evaluate the ability of bedside emergency Doppler/Echocardiographic (ECOCG/DP) studies in the diagnosis of mechanic complications during acute myocardial infarction (AMI). DESIGN: Retrospective analysis of 44 fatal AMI cases, studied by ECOCG/DP and with diagnostic confirmation by surgery and/or necropsy. SETTING: Patients (pts) with AMI admitted to an Intensive Care Unit of a tertiary Hospital (UCIM), Hospital de Santa Maria. PATIENTS: 44 fatal AMI cases were analysed (24 men and 20 women; mean age +/- SD: 72 +/- 9 years) and were divided in two groups according to Killip classification in Group 1 (III/IV): 35 pts and Group 2 (I/II): 9 pts. METHODS: ECOCG/DP was performed in a routine basis at admission, using all standard views and by subcostal view when in an emergency scenario. RESULTS: In 20 pts with bad left ventricular function (LVF) (Group 1) at admission, ECOCG/DP monitoring showed that death was due to worsening of LVF, which was confirmed by necropsy. In the other 15 pts of this group, ECOCG/DP documented the clinical diagnosis of cardiac rupture (free wall: 4 pts; papillary muscle: 4 pts; interventricular septum: 7 pts) which was confirmed by surgery and/or necropsy. In the 9 pts of Group 2, ECOCG/DP disclosed, at admission, good LVF in all. In 5 pts there was a sudden worsening clinical status, and ECOCG/DP showed a severe pericardial effusion with right chambers collapse, highly suggestive of free wall rupture also confirmed at necropsy. In the other 4 pts, ECOCG/DP showed aggravation of wall motion abnormalities and of LVF without rupture, once again in agreement with necropsy. Five clinical cases are presented for illustration of this issue. CONCLUSION: In the 44 fatal AMI cases of our study there was complete agreement between the ECOCG/DP and necropsy studies. In AMI patients, ECOCG/DP monitoring can in a routine basis, evaluate wall motion abnormalities and LVF. In an emergency setting ECOCG/DP can diagnose all the mechanic complications with a great certainty.

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.
