1. CRITERIA, PROTOCOLS AND REPORTING FORMS FOR INITIAL LEFT VENTRICULAR ASSIST DEVICE CLINICAL TRIALS - Norman, John C.; Bernhard, William F.

2. AN INTRACORPOREAL (ABDOMINAL) LEFT VENTRICULAR ASSIST DEVICE, XXII: Précis and State of the Art - Norman, John C.

3. BIOCHEMICAL, HEMATOLOGIC AND COAGULATION VALUES IN THE HEREFORD CALF - Edmonds, Charles H.; McMillan, M. Katharine; Hughes, David A.; Milam, John D.
Biochemical, hematologic and coagulation values have been determined in normal Hereford calves of both sexes, two to six months of age. These data generally agree with those of others and indicate a similarity in calves irrespective of their age, sex or breed. Prothrombin times are markedly longer in the calf than in man. This has resulted in alterations of anticoagulation regimens after implantation of mechanical circulatory support systems.

4. MYOCARDIAL REVASCULARIZATION USING INTERNAL MAMMARY ARTERY - Gerami, Sohrab; Nunnally, Lester C.; Scott, Meredith L.

5. BLUNT TRAUMA TO THE ABDOMEN WITH ARTERIAL INJURY - Coopwood, Thomas B.

6. CLINICAL APPLICATION OF INTRAOPERATIVE COUNTERPULSATION WITHOUT BALLOON PUMPING - Tamari, Yehuda; Frantz, Stephen L.; Beil, Arthur R.; Degnan, Thomas J.; Siedman, Steve; Garfinkle, Terry J.; Newman, Joel C.; Kaplitt, Martin J.

7. MYOCARDIAL INFARCTION FOLLOWING CAROTID ENDARTERECTOMY - Rubio, Pedro A.; Guinn, Gene A.
Myocardial infarction has been the major cause of mortality following operation for cerebrovascular insufficiency. In our institution, a clinical diagnosis of coronary artery disease was made in 37 of 125 (29.6%) consecutive male patients having carotid endarterectomy. Six of these 37 patients developed postoperative myocardial infarction. In contrast, none of the 88 patients without coronary artery disease developed myocardial infarction. A more recently treated group of 20 patients who had undergone carotid artery surgery and had previously undergone coronary artery bypass for angina did not develop postoperative myocardial infarction. These data suggest that in patients with both coronary artery and...

9. EJECTION PHASE INDICES OF LEFT VENTRICULAR CONTRACTILITY - Hernandez-Lattuf, Pedro

10. LEFT VENTRICLE TO ABDOMINAL AORTA CONDUIT FOR RELIEF OF AORTIC STENOSIS - Cooley, Denton A.; Norman, John C.; Mullins, Charles E.; Grace, R. Randall

11. BEN FRANKLIN AND OPEN HEART SURGERY - Comroe, Julius H.; Dripps, Robert D.

12. RADIOLOGIC CASE PRESENTATION - Wagner, M. L.; Singleton, E. B.; Dutton, R. V.

13. Evaluation of a new modified pediatric bubble oxygenator - Reed, Charles C.; Malloy, Kenneth P.; Clark, Diane K.
A comparison was made of the S-070 Pediatric Bubble Oxygenator, which was unreliable above flow rates of approximately 1.5 L/min, with a modified S-070A, which proved to be extremely efficient to flow rates of 2.5 L/min.

14. The reality of a self-occluding pump head: Case report - Seiferd, Susie; Clark, Diane K.; Reed, Charles C.
A malfunction of an oxygenator pumphead during aortocoronary bypass surgery is described. Corrections were made and the operation proceeded without further incident. Although this malfunction is extremely rare, it is reviewed in detail to alert perfusionists to the possibility of such an occurrence.

15. A clinical trial of the Bentley BOS-5 pediatric oxygenator - Carmon, R. Park; Clay, Cristine C.; Stafford, Trudi; Reed, Charles C.
The performance of the Bentley BOS-5 pediatric oxygenator was evaluated on the basis of its response to maintain arterial pH between 7.35 and 7.45, arterial pO2 between 100 and 200 mm Hg, and arterial pCO2 between 35 and 45 mm Hg (Texas Heart Institute perfusion protocol). The oxygenator was found to be efficient at all flow rates employed; however, the pO2 parameter could not be consistently maintained within protocol limits, but could be improved when a mixture of 5% carbon dioxide/95% oxygen was used for the duration of a case.

16. Iatrogenic myocardial dysfunction after formalization of the heart - Gómez-Arnau, J.; Criado, A.; Burgos, R.; Horno, R.; Agosti, J.
A 20-year-old patient with myoepicardial echinococcosis was referred to our hospital for surgical treatment. After polycystectomy had been performed, the surgical area was mistakenly washed with formaldehyde solution, and severe myocardial dysfunction ensued. Histological alterations were compatible with toxic cellular damage.

17. Use of interposed polytetrafluorethylene (PTFE) graft in distal splenorenal shunt - Barman, A. Addison; Batiuchok, William; Chaudry, Saqib S.; Creedon, John J.
Two patients with massive upper gastrointestinal hemorrhages required transsplenic decompression of the esophageal varices, but because technical difficulties precluded tension-free anastomoses, interposition of PTFE grafts was used to solve these difficult situations.

18. Transection of the aorta for repair of pulmonary artery branch stenosis after creation of a Waterston shunt - Singh, Arun K.
Closure of a Waterston shunt can usually be performed at the time of corrective surgery, either from the inside of the aorta or by detaching it from outside the aorta and patching the pulmonary artery. We propose a different approach for closing the shunt and repairing pulmonary artery stenosis.

19. Balloon catheter dilatation and thrombectomy for acute aortoiliac occlusion - Archie, Joseph P.
A case of acute distal aortic thrombosis in an elderly high-risk patient was successfully managed with intraoperative thrombectomy and balloon catheter dilatation of the common iliac arteries. Balloon catheter dilatation may be indicated prior to bypass grafting in high-risk patients with acute aortoiliac thrombosis.

20. A normal coronary arteriogram in a very young man with Prinzmetal's variant angina: Case report with review of the literature - Balvanera, Alfredo; Frade, Julio; Zamora, Alberto; Robledo, Jose Luis
The case of a very young man with Prinzmetal's variant angina and a normal coronary arteriogram is described. While in the hospital for diagnosis, he experienced severe chest pain accompanied by transient ST segment elevation. After intravenous administration of Ergonovine Maleate (0.4 mg), spastic obstruction of the right coronary artery was observed. He was treated successfully with nifedipine, and during 4 months of follow-up, he has had no symptoms. Because of the diagnostic interest in this type of angina in a young person, the literature on Prinzmetal's angina has also been reviewed.
