We have discussed several diseases that diffusely affect the pulmonary parenchyma. The diagnostic problem is to separate cardiac pulmonary edema from noncardiac pulmonary edema, diffuse interstitial fibrosis, and lymphangitic spread of carcinoma. Frequently, this may not be possible by radiographic means alone, and additional historic and physiologic information must be obtained. It is also important to know that cardiac pulmonary edema may present in a focal or regional distribution in patients with chronic obstructive pulmonary disease. Several additional radiographic tests may be used to evaluate abnormal pulmonary parenchymal densities seen on the portable chest radiograph, when the differential diagnosis includes increased extravascular water, pneumonia, and pulmonary fibrosis. The easiest of these tests to perform is the gravitational shift test.

The records of 264 pediatric patients with uncomplicated ostium secundum atrial septal defect (ASD) were reviewed. Eighty-seven patients were younger than age 4 years at the time of cardiac catheterization. Subnormal weight gain, frequent pneumonia, cyanosis or tachypnea were present in 26 patients (30%). Of the 36 infants at catheterization, 17 (48%) had the previously described symptoms, including 12 (33%) who had congestive heart failure. Eight of the 36 infants were found to have closed their defect at a subsequent catheterization. Six of 18 patients who underwent cardiac catheterization between 1 and 2 years of age also had spontaneously closed their ASD at subsequent study. Statistical analysis of hemodynamic data revealed no difference (except a smaller shunt size) between ASDs that closed and those that did not in patients who were less than 4 years at initial catheterization. Analysis of hemodynamic data revealed no statistical differences between groups of patients with an ASD who were younger than and those older than 4 years at time of diagnostic study. Patients with ASDs that closed were significantly different from patients with atrial level shunting thought to be secondary to a valve-incompetent foramen ovale with respect to age at initial study (11 versus 2 months, p less than 0.001), mean left atrial pressure (7.7 versus 12.3 mm Hg, p less than 0.02) and difference between mean right and left atrial pressures (1.0 versus 4.2 mm Hg, p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

A child with a large ventricular aneurysm was completely free of symptoms when admitted to the hospital; a chest-x-ray previously performed because of acute pneumonia had evidenced a bulge of the left border of the heart. The diagnosis of left ventricular aneurysm was verified by left ventricular angiography. Selective coronary angiography and angiocardiography of the right heart were also performed.

The "melting sign" can be seen in the radiologic resolution of pulmonary thromboembolism, but is also seen in pneumonia. It's not a pathognomonic radiologic sign and has a rather subjetive character.

To predict hospital costs after coronary artery bypass grafting (CABG) from preoperative characteristics and postoperative complications, 4 analyses of the data were used: (1) a univariate analysis of each preoperative and postoperative variable, (2) a multivariate analysis of the preoperative variables (model 1), (3) a multivariate analysis of the postoperative variables (model 2), and (4) a multivariate analysis of pre- and postoperative variables (model 3). Eight-hundred seven patients who underwent a first-time CABG at Emory University during 1990 were analyzed in this study. Using model 1, the determinants of costs were higher angina grade (p = 0.0006), previous myocardial infarction (p = 0.0133), older age (p = 0.0001), congestive heart failure (p = 0.0001), and a higher number of diseased vessels (p = 0.0001). For model 2, the determinants of costs were adult respiratory distress syndrome (p = 0.0073), intraaortic balloon pumping (p < 0.0001), pneumonia (p < 0.0001), septicemia p < 0.0001), major arrhythmia (p < 0.0001), reexploration for bleeding (p < 0.0001), wound infection (p = 0.0632), neurologic event (p = 0.0013), fluid overload (p = 0.0516), and absence of pericarditis (p = 0.0588). For univariate analysis, the determinants of increased costs were similar to those from models 1 and 2. Although there is considerable variance in hospital costs for any number of complications, utilized resources (costs) increase inexorably as patients have more complications after coronary surgery. The mean cost to the hospital for the 382 patients who underwent CABG and experienced no complications was $16,776.(ABSTRACT TRUNCATED AT 250 WORDS)

Transient electrocardiographic changes in patients with acute cholecystitis, pancreatitis, and pneumonia have been reported in the past. These changes usually are in the form of T-wave inversion, ST-segment depression, and rarely ST-segment elevation in the absence of coronary artery disease. To the authors' knowledge, this is the first report documenting both left ventricular segmental wall motion abnormality and electrocardiographic changes of myocardial injury in the presence of acute pancreatitis.

The bidirectional Glenn operation may be particularly useful as an intermediate procedure before Fontan correction in high-risk patients. From October 1989 through February 1992, 50 patients 1 to 60 months old (median 12) have undergone a bidirectional Glenn operation. Diagnoses included hypoplastic left heart syndrome in 21 patients, pulmonary atresia with intact ventricular septum in 10, tricuspid valve atresia in 9, other complex univentricular heart defects in 9, and Ebstein's anomaly in 1. Mean pulmonary vascular resistance was 2.2 +/- 0.2 Wood U (range 0.5 to 7.3) and mean pulmonary artery area Nakata index was 318 +/- mm2/m2 (range 80 to 821). Additional procedures were performed in 17 patients, including pulmonary artery reconstruction in 15 (29%) and bilateral caval anastomoses in 5 (10%). There were 4 hospital deaths (8%). Two deaths resulted from myocardial infarction in patients with pulmonary atresia with intact ventricular septum and sinusoids and 1 from severe pulmonary vascular disease in a patient with hypoplastic left heart syndrome. There was 1 late death from pneumonia. Actuarial survival is 92 +/- 4% at 1 month and beyond, with a mean follow-up of 13.4 +/- 1 months. Risk factor analysis showed that pulmonary vascular resistance > 3 Wood U and pulmonary artery distortion were associated with increased mortality. Twelve patients have undergone a Fontan procedure at a mean duration after bidirectional Glenn of 18 months with 1 death (8%). The bidirectional Glenn procedure provides excellent palliation in high-risk patients and appears useful as a staging procedure before Fontan correction.

Infections after cardiac pacemaker implantation are rare (0.13 to 12.6%) but potentially severe complications. Staphylococcus is the genus most frequently isolated (72 to 100% of cases). The use of systematic prophylactic antibiotics remains controversial. From November 1991 to October 1993, 207 consecutive patients were submitted to a series of measures designed to reduce the risk of infection: a) intravenous bolus injection of Cefamindole, 15 minutes before implantation, b) cutaneous disinfection with iodinated polyvindone, c) injection of an ampoule of rifampin before closure of the pacemaker in the pouch, d) absence of drainage system. Patients were predominantly female (60.9%), with a mean age of 77 +/- 10 years, frequently suffering from heart disease (53.8%). The indication for implantation was atrioventricular block (39.7%), carotid sinus syndrome (27.5%), atrial arrhythmia (27.5%), resection of the node-His tract (5.3%). This procedure corresponded to the first implantation in 88.4% or replacement of a previous pacemaker in 11.6% of cases and the pacing mode was single-chamber (38.4% or replacement of a previous pacemaker in 11.6% of cases and the pacing mode was single-chamber (38.7%), or double chamber (61.3%). The mean duration of the procedure was 51.5 min +/- 30 min. The mean follow-up was 12.7 +/- 5 months. The overall mortality was 14% (11 cases of cardiac failure, 6 sudden deaths, 4 cerebrovascular accidents, 4 cases of pneumonia, 4 neoplasms). Only one infectious problem (endocarditis, i.e. 0.48%) was observed.

A 53-year-old man with dilated cardiomyopathy underwent left ventriculoplasty (Batista procedure), a new surgical procedure, which reduces ventricular volume to improve left ventricular function. Left ventricular ejection fraction increased from 19.7% to 43.7%. Unfortunately, he died of pneumonia 12 days after surgery. This is the first such procedure in a human in Japan.
