Peripartum cardiomyopathy is a relatively rare complication of pregnancy, characterized by heart failure of obscure etiology during the antepartal or postpartal period. During a 10-year period in our hospital, of 36,882 women who delivered, 6 were diagnosed as having peripartum cardiomyopathy. The incidence in our hospital was estimated as 1:6,147 deliveries. Among these 6 patients, 2 cases with fulminating courses died 1 month after treatment. Two other cases had cardiomyopathy and multiple congestive heart failure and died after 3 years and 6 years. Only one case, whose cardiac size returned to normal within 4 months, completely recovered from this disease. Another survivor with persistent cardiomegaly was followed for 5 years and remained clinically stable. In addition to congestive heart failure, the occurrence of complications such as sepsis, hepatorenal failure, and arrhythmia were the major causes of death. According to the results of our study, return of cardiac chamber size to the normal range indicated a good prognosis. We concluded that the prognosis of peripartum cardiomyopathy depends upon the degree of cardiac dysfunction and the response to therapy.

Five years of experience gained with the CryoCare Extremity Stabilization System (CESS) were evaluated in this study. Twenty-one patients underwent freezing amputation. Five patients died before undergoing surgical amputation. Symptomatic relief, control of odor, decreased demand on nursing staff, and appreciation of the family make this approach valuable even when long-term survival is not anticipated. Ten patients who underwent freezing amputation subsequently underwent surgical amputation and were discharged. Six patients underwent freezing and surgical amputation but died prior to discharge. The patients selected for the freezer application were deemed to be prohibitive operative risks because they were experiencing systemic toxicity from their ischemic limb and underlying diseases. Six patients demonstrated myoglobinuria prior to freezing which cleared with CESS. The physiologic amputation allowed stabilization of medical problems including cardiac arrhythmias, congestive heart failure, sepsis, renal failure, diabetes, and respiratory failure. Freezing of an ischemic extremity allows delay in amputation enabling physicians to achieve maximal medical stabilization. It permits symptomatic relief in patients whose long-term survival is not anticipated. Physiologic freezing amputation should be included in the repertoire of all surgeons.

We retrospectively reviewed the records of 88 patients who underwent a total of 95 in-situ bypass operations. Seventy-eight percent were diabetics, 56% hypertensives, 23% had a history of a myocardial infarction, 18% a previous stroke or transient ischemic attack, and 19% a renal transplant. Eighty-eight percent had general anesthesia. Eighty-four percent of the operations extended distal to the popliteal trifurcation, with an average operating time of 5.12 +/- 1.25 hours and blood loss of 354 +/- 239 ml. The overall mortality was 4.2%, with two deaths due to wound sepsis and two deaths due to congestive heart failure. The perioperative myocardial infarction rate was 6.3%. The average age of the patients who died was significantly greater than the age of those who survived (78.2 +/- 17.7 years vs. 59.9 +/- 14.8 years, p less than 0.05). The Goldman risk index was not helpful in predicting cardiac complications. The results show that patients undergoing in-situ bypass operations are at high risk for cardiovascular complications. Aggressive perioperative evaluation and management similar to that shown to reduce such complications in abdominal aortic aneurysm surgery should be helpful.

This report describes four infants with hepatic hemangioendotheliomas and cardiac failure who had extensive portal venous and systemic collateral arterial supply complicating hepatic arterial embolization. One patient with diffuse hepatic hemangioendothelioma and extensive portal vein supply but minimal systemic collateral arteries showed no improvement after technically successful hepatic artery embolization and died with disseminated intravascular coagulation and sepsis. A second infant with extensive portal vein and collateral supply died without undergoing embolization. Two patients had portal vein-hepatic vein fistulas as well as an extensive systemic arterial supply. Both infants tolerated staged hepatic and collateral artery embolization, although one patient died of congestive heart failure, probably related to pulmonary hemangiomas. The authors conclude that angiographic study of the potential collateral vessels and portal venous circulation should be performed before embolization. Patients with shunting from the portal vein to the hepatic vein and minimal systemic arterial collateral circulation should not undergo hepatic artery embolization.

Perioperative circulatory disorders in patients may take the form of a transitory reduction in oxygen transport to the peripheral tissues (pre-shock), manifest circulatory insufficiency in the presence or absence of concomitant heart insufficiency or general congestive heart failure due to the destabilization of an preexisting heart disease. The least problematical stage in this programme of therapy is the treatment of transitory perioperative circulatory insufficiency by manipulation of the oxygen transport system using the following means: comparative volume optimization [according to the central venous pressure (CVP)], positive inotropic support with dobutamine (5-10 micrograms.kg-1.min-1), monitoring of the blood pressure, heart rate and oxygen consumption and, in severe cases, insertion of a Swan-Ganz catheter. In manifest circulatory insufficiency, sepsis or acute congestive heart failure, the Swan-Ganz catheter seems to be obligatory. In such cases, the positive inotropic therapy is based on catecholamines of medium (dobutamine) or high (epinephrine) positive inotropic efficacy, as a normal pattern and functioning of beta-adrenoceptors can be assumed in such cases if there is no history of cardiac insufficiency. The systemic vascular resistance (SVR) is adjusted to 800-1200 n.s.cm-5 to relieve the working capacity of the heart and to maintain sufficient perfusion pressure by means of constrictors (phenylephrine, norepinephrine) or dilators [nifedipine, nitroglycerin or, if necessary, angiotensin-converting-enzyme (ACE) inhibitors].(ABSTRACT TRUNCATED AT 250 WORDS)

Septic complications after cardiac catheterization and percutaneous transluminal coronary artery angioplasty are distinctly uncommon. However, we have recently treated nine patients with sepsis and life-threatening complications after cardiac catheterization alone or after catheterization and subsequent percutaneous transluminal coronary angioplasty. The common denominator in all patients was either repeat puncturing of the ipsilateral femoral artery or leaving the femoral artery sheath in for 1 to 5 days after the procedure. Two patients died as a direct result of their septic complications. One death occurred in a patient in whom bacterial endocarditis with congestive heart failure developed, and the other patient had a large retroperitoneal hematoma that became secondarily infected. Infected aneurysms that were successfully treated developed in three patients. Our study suggests that colonization of the needle tract by skin flora predisposes to septic complications if repeat arterial punctures are required or if a femoral artery sheath is left in place for more than 24 hours. Patients in whom sepsis develops after these procedures should be initially treated with antibiotics effective against gram-positive organisms. CT scanning or angiography should be considered for patients with persistent sepsis, septic emboli, and abdominal or flank pain. Infected aneurysms require resection or ligation because of the propensity of these aneurysms to rupture.

We have reviewed 116 cases of bacterial endocarditis treated surgically and 26 cases treated medically since 1973. There were 123 patients with native valve endocarditis and 19 patients with prosthetic valve endocarditis. Overall, the left-sided valves were infected most frequently. There were 10 cases with right-sided valves involved. Multiple valves were infected in 6 patients. There were 6 perioperative deaths in the surgical group. The most common cause of death was multi-organ failure associated with uncontrollable sepsis. The overall operative mortality for active endocarditis was 7.7% (4/55), and for healed endocarditis, 3.3% (2/61). For active native valve endocarditis, the mortality was 4.2% (2/48), for healed native valve endocarditis, 3.6% (2/55), for active prosthetic valve endocarditis, 28.6% (2/7), and for healed prosthetic valve endocarditis, 0%. There was no difference in the operative mortality between active native valve endocarditis and healed native valve endocarditis. The mortality of active prosthetic valve endocarditis was significantly higher than that of active native valve endocarditis (p less than 0.01). Of the 26 patients treated medically, 7 died during the initial hospitalization. The major factor related to mortality in the medically treated patients was persistent sepsis (four patients), and congestive heart failure (three patients). The overall mortality of the medical group for active valve endocarditis was 15% (3/20), and for active prosthetic valve endocarditis, 67% (4/6). We conclude that patients with infective endocarditis with significant valve lesions who are unresponsive to medical therapy should be considered for urgent surgery.

Forty-eight patients with acute renal failure (ARF) who were referred to the Department of Renal Medicine, Singapore General Hospital for acute dialysis between August 1985 and August 1989 were studied retrospectively to identify risk factors associated with ARF that serve as prognostic indicators. There was no difference in the mean age of survivors and non-survivors (49.5 +/- 17.5 years vs 53.5 +/- 18 years, p greater than 0.05). The overall mortality rate was 52%. ARF as a result of surgical complication had a higher mortality rate in comparison to ARF from medical complications (66% vs 50%, p greater than 0.05). Septicaemia was the most common cause of ARF requiring dialysis. Hepatobiliary sepsis was the most frequent cause of septicaemia. Pre-dialysis serum urea and creatinine levels, and the number of dialysis treatments did not affect the outcome. Poor prognostic indicators included oliguria or anuria, fluid overload and coma. Patients tended to have a worse outcome if they had more than three risk factors taken from the following list:-decreased renal perfusion, assisted ventilation, coma, gastrointestinal dysfunction, recent surgery, sepsis, congestive heart failure, hepatobiliary dysfunction, malignancy, diabetes mellitus, chronic renal insufficiency and poor nutritional status. Early referral of patients with septicaemia due in particular to hepatobiliary infection may improve the prognosis.

A female child with Weaver syndrome is described. She did not show the excessive growth characteristic of this syndrome until after adequate caloric intake was achieved by feeding through a gastric feeding tube. Her inadequate nutrition was a result of feeding difficulties during infancy. In addition, she had recurrent pulmonary infections, apneic spells, and severe developmental delay. She died at 16 months of sepsis, congestive heart failure, and respiratory arrest. The autopsy revealed marked atrophy of the brain and cardiac ventricular hypertrophy. Most of the brain changes were thought to be from hypoxia.

A 1-month-old boy without precedent clinical signs of heart disease died unexpectedly. At autopsy, the child was found to have origin of the right coronary artery from the left sinus of Valsalva immediately leftward to the thickening of the aortic wall at the cuspal commissure and adjacent to the ostium of the left main coronary artery. The association of this coronary anomaly with otherwise unexplained prenatal or early postnatal death has only recently been appreciated as a potential cause of sudden infant death and mimic of sepsis, dysrhythmias, congestive heart failure, or metabolic storage diseases.
