A 9-month-old male with asplenia and complex congenital heart disease experienced progressive stenosis of an anomalous pulmonary venous connection. He developed
pulmonary edema
and growth failure. Two stents were placed concentrically to relieve the stenosis, and the
pulmonary edema
and growth failure resolved. Definitive surgery was accomplished 8 months later.

The postoperative courses of 112 patients with pulmonary disease (59 with obstructive disease = Group 0, 38 with restrictive disease = Group R and 15 with mixed disease = Group M) who underwent elective coronary artery bypass grafting were retrospectively reviewed. Preoperative pulmonary function test (percentage of vital capacity = %VC and percentage of forced expiratory volume at 1 second = FEV1.0%) of these group showed typical abnormal values, and velocity ratio of 50% and 25% of maximum expiratory flow volume (V50/V25) of each groups were measured abnormal values (3.99 +/- 1.44 of Group O, 4.26 +/- 1.42 of Group R and 3.74 +/- 1.82 of Group M). The our strategy for these groups were a). Using skeletonization method for harvesting internal mammary artery (IMA) b) Take care not to injure the phrenic nerve and open the pleural cavity as surgical techniques (Harvesting IMA) and c) Administration of theophylline derivatives and corticosteroids to prevent bronchospasm d) Administration of concentrated serum albumin and diuretics to prevent
pulmonary edema
as therapeutic measures. The length of stay in the intensive care unit and ventilation time of each groups were not significantly longer. Patients of group M had more respiratory complications (atelectasis, pleural effusion, pneumothrax, bronchospasm, and pneumonia) than did patients of group R (p < 0.05), but did not more nonpulmonary complications and hospital deaths. The four in hospital deaths (2 with group O, 1 with group R and 1 with group M) were not directly related to pulmonary complications. Thus, result of CABG in patients with pulmonary impairment definitely proved to be satisfactory by our strategy, but mixed pulmonary diseased significantly had more pulmonary complications.

A 76-year-old woman was referred to our hospital because of postinfarction ventricular septal perforation (VSP). VSP occurred twelve days after acute myocardial infarction and resulted in interventricular shunt with Qp/Qs of 4.8. Because she suffered from
pulmonary edema
and oligouria, she underwent emergent surgical treatment after application of the intraaortic balloon pump. The infarction involved whole of right ventricle and the infero-posterior wall of left ventricle, and the location of the perforation was infero-septum with the size of 10 x 6 mm. A bovine pericardial patch was tailored in a triangular shape of approximately 7 x 7 x 5 cm. The base of the patch was sutured to the fibrous annulus of the mitral valve and medial margin of the patch was sewn to healthy septal endocardium. And the lateral side of the patch was sutured to the posterior wall of the left ventricle. Because of difficulty in weaning of the cardiopulmonary bypass, a percutaneous cardiopulmonary support system (PCPS) was inserted via femoral artery and vein with a flow support of 2.0 L/min. After 4 days support of PCPS, improvement of right ventricular function was detected by echocardiogram and PCPS was removed. While PCPS support, low dose heparin to maintain ACT level around 150 seconds was continuously administered. Any complication including bleeding and thrombosis was not remarkable. The patient was discharged on the 53th postoperative day, and is now doing well.

To clarify the optimal management and delineate the characteristics of patients with severe left main disease and cardiogenic shock as a result of an acute anterolateral myocardial infarction (left main shock syndrome), we analyzed the course of 13 such patients from September 1989 to June 1997. Of the 13 patients, 7 (53.8%) were managed with emergency coronary angioplasty (group A), 3 (23.1%) were treated with emergency coronary angioplsty following coronary bypass graft surgery (group B) and 3 (23.1%) underwent emergency coronary bypass graft surgery alone (group C). The interval from the beginning of myocardial ischemia to revascularization was 266 +/- 303 min. The degree of diameter stenosis found in the left main coronary artery was 98.1 +/- 1.8%. Overall in-hospital mortality for the 13 patient with left main shock syndrome was 76.9% (group A: 7/7; group B: 1/3; group C: 2/3, NS) and operative mortality was 61.5% (group A: 6/7; group B: 0/3; group C: 2/3, p = 0.03). When all 13 patients were examined together, the presence of ventricular tachycardia (VT) x ventricular fibrillation (Vf) was found to be the most powerful univariate predictor of operative death (p = 0.03). This is, 7 (87.5%) of the 8 patients with VT x Vf at presentation died within 30 postoperative days, and only 1 (20%) of the 5 patients without VT x Vf died (p = 0.03). Age, percent stenosis of the left main or right coronary arteries, the interval from the beginning of myocardial ischemia to revascularization, intubation, systolic pressure, fractional shortning, pulmonary artery pressure, pulmonary capillary wedge pressure, coronary risk factors,
pulmonary edema
, mitral regurgitation and percutaneous cardiopulmonary support failed to attain univariate significance at the P = .1 level. The postoperative peak CPK level was 15665 +/- 6710 IU/1 in operative death compared to 4733 +/- 2749 IU/1 in operative survival (p = 0.01). In conclusion, emergency coronary angioplasty following coronary bypass graft surgery for left main shock syndrome has been a very successful therapeutic option. Finally, for the entire group of 13 patients with left main shock syndrome, VT x Vf significantly decreased short-term survival.

In lung transplantation, the safety period of the ischemic time of the graft is within 6 hours. Because of the problem of donor shortage, it is essential to extend the safety period of the preservation time of the donor lung. However, the longer the preservation time is, the more severe is the resulting ischemia-reperfusion injury. This study was designed to evaluate the efficacy of initial controlled perfusion pressure in the reduction of ischemia-reperfusion injury in a 24-hour preserved lung. Japanese white rabbit lungs were flushed with a low-potassium dextran solution (4C, 500 ml) after injection of prostaglandin E1 (20 microgram, bolus via PA) and submersed in the same solution for 24 hours at 4C. After preservation, the left lung was reperfused using an extracorporeal lung perfusion model which comprised of a closed circuit combined with a membrane deoxygenator. Assessment of lung function included gas analysis of influent and effluent blood and mean pulmonary artery perfusion pressure. Then the lung wet/dry weight ratio was calculated. In group I of the control group (n=6), the left lung was reperfused immediately following flushing (without preservation) at a flow rate of 50 ml/min for 60 minutes. In groups II and III, grafts were stored for 24 hours. In group II, grafts (n=6) were reperfused at a flow rate of 50 ml/min for 60 minutes. In group III (n =6), the flow rate was controlled by maintaining the perfusion pressure below 30 mmHg during the initial 5 minutes and was increased to 50 ml/min for the subsequent 60 minutes. In group II, the mean pulmonary artery pressure during perfusion increased rapidly, and oxygenation deteriorated. All grafts developed
pulmonary edema
within 12 minutes after reperfusion. Examination of the specimen revealed that the peripheral lung was not perfused. In group III, the mean pulmonary artery perfusion pressure was maintained below 30 mmHg, and oxygenation was preserved sufficiently throughout the experiment (delta PO2 > 100 mmHg) with no significant difference from control values. In conclusion, ischemia-reperfusion injury of the 24-hour preserved lung was attenuated prominently by controlling initial perfusion pressure for 5 minutes.

Extracorporeal membrane oxygenation (ECMO) is used as circulatory support or bridge to transplantation in patients with severe left ventricular (LV) dysfunction. Left heart decompression is needed to reduce
pulmonary edema
, prevent pulmonary hemorrhage, and reduce ventricular distention that may aid in recovery of function. We reviewed our experience from November 1993 to December 1997 with 10 patients having severe LV dysfunction (7 myocarditis, 3 dilated cardiomyopathy) who required circulatory support with ECMO and who underwent left heart decompression with blade and balloon atrial septostomy (BBAS). Patients ranged in age from 1 to 24 years (median, 3 years). Indications for BBAS included left atrial/left ventricular distension (10),
pulmonary edema
/hemorrhage (9), or severe mitral regurgitation (2). BBAS was performed electively in eight patients and urgently in two patients. BBAS was performed while on ECMO in seven patients and pre-ECMO in three. A femoral venous approach was used in all patients. ECMO patients were fully heparinized. Transseptal puncture was required in nine patients while one patient had a patent foramen ovale. Blade septostomy was performed in all patients. Enlargement of the defect was then performed by stationary balloon dilation in nine and Rashkind balloon atrial septostomy in one. Balloon diameters ranged from 10 to 20 mm. Sequential balloon inflations were performed in some patients. Adequacy of the atrial septal defect (ASD) was confirmed by pressure measurement and echocardiography. Adequate left heart decompression was achieved in all patients.
Pulmonary edema
improved in nine of nine patients. Left atrial mean pressure fell from a mean of 30.5 mm Hg, (range, 12-50 mm Hg) to 16 mm Hg (range, 9-24 mm Hg). Left atrial to right atrial pressure gradient fell from a mean of 20 mm Hg pre-BBAS to 3 mm Hg post-BBAS. ASDs ranged in size from 2.5 to 8 mm (mean, 5.9 mm). Complications included needle perforation of the left atrium without hemodynamic compromise (one), ventricular fibrillation requiring defibrillation (one), and hypotension following BBAS which responded to volume infusion (two). Duration of ECMO ranged from 41 hr to 704 hr (mean, 294 hr). Seven patients survived and four patients had recovery of normal LV function. Of those who recovered, two had no ASD at follow-up while two ASDs are patent 14 days and 3 months post-BBAS. Three patients underwent successful cardiac transplantation. Three patients died, all of whom had multisystem organ failure with or without sepsis. A patent ASD was noted at transplant (three) or autopsy (two). No patient required a second BBAS. BBAS alleviates severe left atrial hypertension and
pulmonary edema
. In addition, BBAS avoids the potential bleeding complications of surgical left heart decompression. Stationary balloon dilation of the atrial septum is an effective alternative to Rashkind balloon septostomy in older patients. BBAS achieves left heart decompression that may permit recovery of LV function or allow extended ECMO support as a bridge to transplant.

Carotid angioplasty and stenting to treat extracranial carotid stenosis is an alternative (as yet not widely accepted) to high-risk surgery, but its safety and efficacy are little known, especially in elderly patients. We reviewed our 3-year experience of treating 100 elderly patients (> 65 years old) considered to be inoperable (76 men, 24 women, mean age 76+/-10 years, mean follow-up 18+/-9.2 months) and present two case histories. Most (85%) were symptomatic (transient ischemic attacks in 60, stroke in 25); 80 had concomitant coronary artery disease (severe in 30 [defined by > 70% stenosis in two or more epicardial coronary arteries or the left main coronary artery]) and 25 had severe left ventricular dysfunction (ejection fraction < or =20%). The procedure was technically successful in all patients; there was one major stroke and no patient died. Postprocedure, 15% had minor complications: reversible neurological deficit (5%),
pulmonary edema
(3%), prolonged hypotension (3%), vascular access complications (3%), and neck hematoma (1%). Over 90% of patients were discharged home within 24 hr.

A female with mitral valvular disease presented an acute myocardial infarction. She suddenly complained of recurrent chest pain with symptoms of
pulmonary edema
. The angiogram evidenced multiple coronary thromboemboli. A combined strategy using intracoronary thrombolysis, a platelet glycoprotein IIb/IIIa antagonist (abciximab) and percutaneous transluminal coronary angioplasty to help disrupt the thrombus was performed. Clinical and angiographic signs of coronary reperfusion were rapidly achieved. No bleeding complications appeared.

In discordant xenotransplantation, the recipientOs blood initiates hyperacute xenorejection (HXR). We hypothesized that HXR-related
lung edema
may be reduced if a new xenograft is perfused by blood which previously has perfused another xenograft. In a syngeneic control group (n = 6), a rat lung (lung XR) was perfused by rat blood (blood AR), following which the blood was collected (blood BR). After another rat lung (lung YR) was perfused by blood BR, the blood was collected (blood CR). In a xenogeneic experimental group (n = 6), a guinea pig lung (lung XG) was perfused by rat blood (blood AG), and the blood was collected (blood BG). Then, another guinea pig lung (lung YG) was perfused by blood BG, and once more the blood was collected (blood CG). White blood cells (WBC), polymorphonuclear leukocytes (PMN), red blood cells (RBC), hemoglobin, hematocrit, and complement (CH50) in the blood were measured pre- and post-perfusion. The wet/dry weight ratio (W/D) of the lung was calculated after the perfusion. WBC and PMN were higher in blood CR/BR than in blood BR/AR. CH50 was higher in blood CG/BG than in blood BG/AG. RBC, hemoglobin, and hematocrit were not different among the blood AR, BR, CR, AG, BG, and CG. The W/D was not different between lung XR and lung YR. The W/D of lung YG was lower than lung XG. In conclusion, the
lung edema
associated with HXR is reduced when blood which has perfused another xenograft is used to perfuse the new xenograft without anemia, and complement plays a critical role in reducing
lung edema
.
