In the period 1957--1976 481 patients under 40 years of age were operated on. Dyspnoea and increased fatigue were dominating symptoms in more than half of the series. In 202 cases the anomaly was discovered at routine examination in the absence of relevant symptoms. Almost half of the patients were operated under hypothermia, in the others extracorporeal perfusion was used. Four hospital deaths occurred, two of which were related to cardiopulmonary bypass.

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 patient who had a 5-year history of a low-grade nongenital pelvic leiomyosarcoma was evaluated for worsening dyspnea, hypertension, and jugular venous distension. An echocardiogram revealed a large right atrial mass. At surgical exploration, metastatic leiomyosarcoma was found within the inferior vena cava extending from below the renal veins up into the right atrium. Using cardiopulmonary bypass with profound hypothermia and circulatory arrest, the inferior vena cava was opened below the renal veins, and the tumor was transected. That portion of the tumor above this transection was then extracted through a right atriotomy. Resection of the pelvic tumor was not thought to be feasible. The patient remains asymptomatic with stable pelvic tumor 1 year after the procedure.

In the attempt to correlate clinical findings with serum levels of aldrin, sixteen patients were followed-up after acute intoxication by this agent. Eight of them, males and females, aged from 1 to 37 years, presented no or light symptoms (some discomfort and nausea). The serum of one of these patients was found to contain 16.6 ppb of aldrin and that of another, 1.41 ppb of dieldrin. A group of five patients, aged from two to 30 years, showed symptoms of moderate severity, reporting nausea, vomiting, drowsiness, dyspnea, sweating, mild jerking, rise in blood pressure and convulsions. Of these cases, two were accidental and three were attempted suicides, the majority achieving complete recovery within 24 hours. Serum levels of aldrin were between 6.98 ppb and 26.3 ppb and of dieldrin between 82.00 and 314.18 ppb. We found three severe cases, aged from 21 to 35 years, two attempted suicides and one occupational case. Two of these patients died and one of them presented hypothermia, coma, absence of reflexes and generalized convulsions, and another presented abdominal pain, paleness, sweating, cold extremities, dyspnea, hyperthermia and generalized convulsions. In the first one that died the serum levels were: of aldrin 30.00 ppb and of dieldrin 720 ppb. In the other levels of 747.3 ppb of aldrin and 1,314.00 ppb of dieldrin were found. The third had less serious symptoms and presented serum levels of aldrin of 31.05 ppb and of dieldrin 147.11 ppb.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of a week old female baby, admitted because of apathy, hypothermia, dyspnea, jaundice and cyanosis is described. She had the characteristic phenotype of Turner's syndrome with normal karyotype. Signs of severe heart failure were present. Therapy with diuretics, digoxin, dopamine and mechanical ventilation were unsuccessful, and the patient died several hours after her admission. The anatomopathological examination revealed the presence of hypoplastic left heart syndrome with mitral atresia and aortic atresia, atrial septal defect, double outlet right ventricle, and a patent ductus arteriosus.

Of 1225 patients undergoing open heart surgery over an 18-month period, 13 had diaphragmatic dysfunction due to phrenic nerve injury; 11 of these had internal mammary artery grafting. Nine had diaphragmatic dysfunction on the same side as the internal mammary artery graft side (7 bilateral and 2 unilateral) as determined by fluoroscopy during phrenic nerve stimulation. Although topical cardiac hypothermia has been the prevailing mechanism for diaphragmatic dysfunction due to phrenic nerve injury after open-heart surgery, dissection of the internal mammary artery with electrocautery, traction, or vascular compromise to the phrenic nerve, or a combination, could be additional factors. Rocking bed ventilation was instituted to facilitate passive diaphragmatic movement and airway decannulation and was continued at home until the phrenic nerve or nerves recovered. These patients were followed up clinically and with serial measurements of vital capacity, respiratory muscle strength, phrenic nerve latency, and fluoroscopy to determine recovery rate. Phrenic nerve recovery occurred from 4 to 27 months after surgery. This recovery was heralded by the patients' ability to assume the supine position without dyspnea when use of the rocking bed was discontinued. Unilateral diaphragmatic recovery was sufficient for the restoration of symptom-free supine posture.

The authors relate their experience concerning the surgical correction of congenital coronary fistula. Between May 1971 and June 1986, 9 patients (4 boys and 5 girls) aged from 17 days to 49 years were operated upon at the Division of Cardiac Surgery of Bergamo (Ospedali Riuniti). All the patients, except three who were asymptomatic, showed early cardiac failure or dyspnoea on effort and angina in the elderly. At the physical examination a continuous murmur was heard in 8 cases; the chest x-ray showed significant cardiomegaly and on the electrocardiogram a right/left ventricular hypertrophy pattern was detected in 5 patients. All the patients underwent cardiac catheterization and a coronary angiography. The left-to-right shunt ranged from 60% to 250% of the cardiac output. The anomalous communication affected the right coronary artery in 7 cases and the left in 2, opening into the right atrium in 4 patients, into the right ventricle in 3 and into the pulmonary artery in 2. All patients but one, in whom division and suture were the only necessary procedures, underwent correction by means conventional cardiopulmonary by-pass with moderate hypothermia. In 3 cases closure through the coronary artery was preferred, in 1 through the right ventricle and in 2 transpulmonary. There was only 1 late death which occurred in a 3 year-old patient due to renal failure. After a mean follow-up of 6 years, 7 patients are to be asymptomatic while 1 patient had to be reoperated for a significant residual shunt.

Fifteen patients with intracavitary cardiac tumors were operated on at the Kobe University Hospital between September 1977 and January 1984. Three of the patients were men and twelve were women. They ranged in age from 9 to 75 years. Their symptoms were chest pain, dyspnea, cough, palpitation and syncope. Definite diagnosis was confirmed by echo- and cineangiocardiography. There were 14 benign tumors consisting of 13 myxomas, one leiomyoma and one malignant myxosarcoma. The left atrium was the most common chamber involved (12 instances), followed by the right atrium (3). Surgery was performed in all cases under cardiopulmonary bypass with moderate hypothermia and cold crystalloid cardioplegia. Tumors were removed en bloc at the base with their attachment to the atrial septum or free wall in all cases. Three patients underwent concomitant mitral annuloplasty or mitral commissurotomy. Two cases with left atrial myxoma died postoperatively: one case associated with mitral annuloplasty died of congestive heart failure due to newly developed chordal rupture two months after surgery, and the other died of congestive heart failure 13 months after the first operation. Re-excision for recurrence of the myxosarcoma in the left atrium was performed in the latter case as a second surgical procedure. The remaining 13 cases with benign tumors are doing well and are without recurrence. From these favorable results, surgical intervention should be recommended prior to the occurrence of heart failure and severe complications such as coronary or peripheral embolism whenever cardiac tumors are detected by non-invasive echocardiography and cineangiocardiography.

Cyclopiazonic acid (CPA) was found to have many pharmacological properties in common with the antipsychotic drugs chlorpromazine and reserpine. Thus, in mice CPA at ip doses of 5-14 mg/kg body weight produced hypokinesia, hypothermia, catalepsy, ptosis, sedation without loss of righting reflex, tremor, gait disturbance, dyspnoea, opisthotonus, atypical convulsion and prolonged barbiturate-induced sleep. The ip LD50 of CPA was found to be 13 +/- 0.05 mg/kg. The tremors induced by near-lethal doses of CPA were associated with voluntary or forced movements (action tremors); they worsened during the days following treatment, but they were weak compared with the exhausting and continuous tremors of the whole body caused by 20 mg tremorine/kg (used for comparison). When death occurred only 24-259 min after administration of CPA (11-14 mg/kg), it was preceded by dypsnoea, cyanosis, opisthotonus and clonic leg movements and tonic extension of hind legs (convulsions). When death was delayed (2-6 days after CPA administration), it was preceded by prostration, ptosis, hypothermia, tremor and cessation of food and water intake resulting in cachexia; convulsions were not seen in this group of mice. CPA did not affect the rate of convulsion or death caused by either maximal electroshock or metrazol administration but it did delay the onset of metrazol-induced seizures. In rabbits, 10 mg CPA/kg body weight initially produced tachycardia, tachypnoea and sedation with an activated electroencephalogram. Of three rabbits given 10 mg CPA/kg one died, and in this rabbit slow delta waves were seen just before and during a brief period with clonic leg movements. In this animal death was accompanied by tonic extension of the hind legs, respiratory arrest and cardiac fibrillation; and epileptiform EEG was not seen at any time. The unexpected EEG activation with sedation in rabbits treated with CPA was similar to the effect of reserpine on EEG.

We report a rare case of hydatidosis of the right heart. Our young patient had know pulmonary hydatidosis and presented precordial chest pain, increasing dyspnea, cough and hemoptysis. Echocardiography, confirmed by angiocardiography delineated the right ventricular cyst. The operation was performed under extra corporal circulation (ECC), moderate hypothermia with cold cardioplegia. The echinococcal cyst was removed after local instillation of 0.5% silver nitrate solution. The postoperative course was uneventful.
