The natural history of hypertrophic obstructive cardiomyopathy (HOCM) is usually characterized by development of mitral insufficiency,
congestive heart failure
(
CHF
) and sudden death. In patients (pts) belonging to at least clinical class III (NYHA) after failed medical therapy (beta-blocking agents and calcium-antagonists) surgery should be considered (by means of transaortic subvalvular myectomy). The history and development of different surgical techniques and procedures has been described in detail since 1958, when Cleland performed the first transaortic subvalvular myotomy. Our surgical series (1963-May 31, 1986) consists of 212 pts (mean age 40 years, range 6-73 years) with typical and atypical HOCM. The total hospital mortality rate was 6.6% (n = 14), which was reduced to 3.8% (n = 6), if only transaortic subvalvular myectomy (TSM) was performed (n = 160). In the group of 52 pts with additional surgical procedures the mortality rate was 15.4% (n = 8). The main problems occurred in pts with additional mitral valve replacement (MVR) (n = 15, three deaths). The rate of HOCM-related complications (secondary VSD, total AV-block, cerebral embolism, intraoperative re-myectomy) and those related to surgery (bleeding, pulmonary embolism, wound dehiscence,
septicemia
) was low. Therefore TSM for HOCM is a low-risk surgical procedure with a good long-term prognosis. However, in pts with a need for additional surgical procedures, the risk is considerably increased. Subjective impression of the pts and hemodynamic data indicate a clear clinical improvement postoperatively. Concerning long-term survival and reduction of the sudden death rate, our data do not allow a final judgement at the moment.

Hemodynamic response after intravenous and oral administration of a new phosphodiesterase inhibitor, CI-914, was studied in 13 patients with severe
congestive heart failure
. Comparable significant increases in cardiac index of 26% (p less than 0.01) and 19% (p less than 0.02) after intravenous and oral administration were observed. Systemic vascular resistance, right atrial and pulmonary artery wedge pressure decreased significantly after intravenous drug administration. Although similar changes occurred after oral administration, they were not statistically significant. Peak CI-914 plasma concentration occurred 2.3 +/- 2.2 hours after oral drug administration and exhibited measurable hemodynamic effects for up to 10 to 12 hours. Seven of the 13 patients received long-term oral CI-914 for as long as 12 weeks and exhibited an improvement in New York Heart Association functional class and exercise capacity. Five patients died with progressive heart failure, 1 patient died suddenly and 1 died of
sepsis
. The drug was well tolerated and appears to have potential as a cardiotonic agent.

Two controversial issues of neonatal transfusion practices, erythrocyte 'booster' transfusions and granulocyte transfusions, are critically reviewed, and current recommendations for transfusion practices are made. Infants should receive erythrocyte transfusions to treat
congestive heart failure
caused primarily by anemia. It is customary to maintain the hematocrit at greater than 40% in neonates with severe respiratory disease, although the efficacy of this practice has not been firmly established. Erythrocyte transfusions seem to be indicated for infants with anemia plus recurrent apnea, poor weight gain or the syndrome of tachycardia, tachypnea, dyspnea and poor feeding for which no other cause can be found. Granulocyte transfusions are likely to benefit seriously ill neonates exhibiting all three of the following: strong evidence of bacterial
sepsis
, neutropenia (compared to age-related normal values) and a diminished marrow neutrophil storage pool. Granulocyte transfusions for septic infants expressing only one or two of these features should be considered to be experimental therapy.

The automatic implantable cardioverter-defibrillator (AICD) has been shown to reduce the mortality rate of patients with malignant ventricular tachyarrhythmias. This report describes experience with implantation of 36 automatic implantable cardioverter-defibrillators (AID-B and AID-BR models) in 22 persons over a 44 month patient follow-up period (mean 19.6 months). There were five deaths: two patients died suddenly 22 and 29 months, respectively, after their second implant, one died of
congestive heart failure
, one died of respiratory failure and one died of catheter
sepsis
. Although 11 (50%) of the 22 patients never received a countershock for a ventricular tachyarrhythmia and are still alive, the other 11 received one or more spontaneous countershocks. Nine patients (41%) experienced spurious shocks during the follow-up period. Assuming that the first shock for presumed ventricular tachyarrhythmia prevented death, the hypothetical cumulative survival of patients at 42 months would have been 34 +/- 14.1% in the absence of an automatic implantable cardioverter defibrillator rather than the actual survival rate of 59 +/- 16.8%. The cumulative device survival of the 36 AID-B units was 92 +/- 5.62% at 15 months but diminished to 37 +/- 14.4% by 20 months. No unit lasted longer than 22 months. There were 12 battery depletions. The number of shocks emitted did not influence unit longevity. The manufacturer's elective replacement indicator is of uncertain validity. Six units remained active 7 to 17 months after surpassing their replacement indicator. The automatic implantable cardioverter-defibrillator prolongs the life of many patients with otherwise intractable arrhythmias.(ABSTRACT TRUNCATED AT 250 WORDS)

Fifty eight patients (aged 8-59 years, mean 27) treated for prosthetic valve endocarditis from January 1966 to January 1985 were studied retrospectively by review of case notes. There were 12 cases of early and 46 cases of late prosthetic valve endocarditis. These developed in 28 patients with an isolated aortic valve, in 26 with an isolated mitral valve, and in four with both aortic and mitral prosthetic valves. Streptococci were the most commonly isolated microorganisms, followed by staphylococci, Gram negative bacteria, and fungi. A surgical (34 cases) or a necropsy specimen (10 cases) from 44 cases was examined. Eighty two per cent of the patients had
congestive heart failure
. Twenty four of the 58 patients were medically treated and 17 died (70% mortality). Combined medical and surgical treatment was used in 34 patients; the main indication for surgery was
congestive heart failure
. Fourteen patients on combined treatment died (40% mortality). Persistent
sepsis
and prosthetic valve dehiscence were the most common early and late operative complications. The most important influences on outcome were
congestive heart failure
, the type of micro-organism, the severity and extent of anatomical lesions, the time of onset of prosthetic valve endocarditis, and the type of treatment. This survey indicates that only patients without
congestive heart failure
or embolic complications and with sensitive micro-organism should be treated medically. In view of the poor prognosis patients with prosthetic valve endocarditis associated with
congestive heart failure
, persistent
sepsis
, and repeat arterial emboli should be treated by early surgical intervention.

A case of thyroid cancer causing right ventricular outflow tract obstruction is described. A 72-year-old woman was admitted because of shortness of breath, some ecchymoses, and marked anasarca. Her liver was palpable four fingerbreadths below her costal margin. Laboratory findings included leukocytosis, marked thrombocytopenia, and an increase in fibrinogen degradation products due to disseminated intravascular coagulopathy. Two-dimensional echocardiography demonstrated a solid mass in the right ventricle, which protruded into the right atrium and main pulmonary artery. Right ventricular outflow tract obstruction and tricuspid regurgitation were demonstrated by contrast echocardiography. These findings were confirmed by CT scans, RI angiography, and contrast angiography. The mass was partially resected from her right ventricle and her tricuspid valve was replaced successfully, but she died of
sepsis
three weeks after surgery. At autopsy, undifferentiated thyroid cancer and cardiac metastasis were verified. To date, only eight cases with initial symptoms of
congestive heart failure
due to right ventricular outflow tract obstruction caused by metastatic intracavitary tumors have been reported. Very rarely have cardiac tumors resulted in disseminated intravascular coagulopathy.

Of 24 patients, aged 6 days to 24 months, undergoing the Senning procedure for transposition of the great arteries, 2 patients died perioperatively (8% operative mortality): 1 patient, a neonate, from
sepsis
and 1 patient, born prematurely and with multiple anomalies, from
congestive heart failure
. One patient died late postoperatively from noncardiac causes. The 21 survivors are clinically well, and in 20 complete hemodynamic and electrophysiologic data were obtained by cardiac catheterization a mean of 13 months after repair. All patients have normal systemic arterial oxygen saturation. Left ventricular function and pulmonary artery pressures are normal in all. None had pulmonary venous obstruction. Narrowing at the junction of the superior vena cava and systemic venous atrium with mean pressure differences of 5 mm Hg or more was found in 4 of the 20 patients, but was clinically manifest in only 1 patient. No abnormality of atrioventricular conduction was seen in response to programmed electrical stimulation. Sinus node dysfunction was present in 6 patients, with abnormalities of both automaticity and sinoatrial conduction. Among these 6 patients were the 5 who were younger than 5 months at operation. The Senning procedure generally results in excellent hemodynamic and electrophysiologic status in patients who undergo operation after the newborn period. Identification of sinus node dysfunction, seen in patients in whom the procedure is performed in the first few months of life, is of concern and identifies a need for close follow-up of sinus node function in this cohort of patients.

Four members of the Anesthetic and Life Support Advisory Committee of the Food and Drug Administration assessed the contribution of isoflurane (Forane) to 45 instances of hepatic dysfunction after isoflurane anesthesia reported to the FDA for 1981-1984. For 29 (64%) of the cases, at least three members concluded that nonanesthetic causes (e.g., hypoxia,
sepsis
, viral infection) explained the hepatic injury. For 16 cases (36%), two or more members concluded that isoflurane might be one of several possible causes of the hepatic injury. In the latter cases, patients tended to be younger, had undergone anesthesia of shorter duration for operations outside the chest and abdomen, had developed symptoms later, had higher plasma transaminase values but lower bilirubin values, and had a lower incidence of eosinophilia, anemia, transfusions, and
congestive heart failure
. The committee concluded that current evidence does not indicate a reasonable likelihood of an association between the use of isoflurane and the occurrence of postoperative hepatic dysfunction.

Serratia marcescens (SM) produced a prolonged outbreak in a neonatal intensive care unit of high level gastrointestinal colonization (10(9) SM/g feces) which in the early part of the outbreak predisposed to respiratory infection. The early outbreak featured a strain of SM carrying a 54 X 10(6) dalton conjugative plasmid which mediated resistance to gentamicin, tobramycin and beta-lactam agents. The second part of the outbreak involved primarily gastrointestinal colonization with SM strains that were plasmid-free. Acquisition of SM was related to very low birth weight (less than 1500 g). Among very low birth weight neonates, SM colonization was associated with pneumonia, patent ductus arteriosus,
congestive heart failure
and
septicemia
. Among neonates greater than 1500 g, SM colonization was associated with bronchopulmonary dysplasia, use of a respirator, patent ductus arteriosus and
congestive heart failure
. Respirator contamination, respiratory tract colonization and consequent pneumonia were reduced by more frequent changing of respirator tubing. Colonized sinks remained chronically colonized with multiresistant SM.

Eleven patients with refractory rheumatoid arthritis were submitted to a total lymphoid irradiation up to a dose of 20 Gy. A constant improvement of clinical symptoms was observed in four out of the eleven patients already during the treatment and in the other patients not later than two months after. The frequency of attacks decreased and the number of joints involved in the attack was reduced. Morning rigidity and joint swellings decreased. One patient developed joint empyemas 4 and 26 months after the treatment. Four patients died in the meantime. In two patients the cause of death were renal insufficiency and a postoperative cardiogenic shock associated with generalized amyloidosis. The third patient died because of a toxically induced left
cardiac decompensation
with
sepsis
that could not be controlled by antibiotic drugs and multiple joint empyemas. The fourth patient developed an abscess after surgical treatment of a Kaposi syndrome. She died three months later from acute left
cardiac decompensation
. The therapy induced a lymphocytopenia with decrease of T helper lymphocytes and unchanged number of T suppressor lymphocytes. The constant therapy results of total lymphoid irradiation in primary chronic polyarthritis is probably due to this modification in the immune regulation.
