OBJECTIVE Sparing the aortic valve has become a surgical option for patients who require repair of aortic root ectasia and have normal valve leaflets. Surgical approaches to valve sparing differ with regard to preservation of the native sinuses of Valsalva. The role of the sinuses and the importance of maintaining them remain controversial. METHODS By(More)
Previously reported methods for the correction of tricuspid atresia involve the use of conduits and/or valves. Since many of the younger patients will outgrow their conduits and the long-term durability of the valve prostheses is open to question, we have devised an operation in which the right atrial (RA) appendage is anastomosed to the right ventricle(More)
A new autotransfusion system was evaluated postoperatively in six patients undergoing aortocoronary bypass surgery. A hollow fiber hemofilter was integrated in the system, making it possible to concentrate the shed blood. The device functioned well, 825 ml diluted mediastinal drainage blood with a hematocrit of 23 was concentrated to a volume of 475 ml with(More)
Acute occlusion of the left main coronary artery (LMCA) is a rare and almost invariably fatal condition. Here, we report on heart salvage in two such cases with CABG aided by emergent retrograde reperfusion as the initial operative step. Both cases were extremely unusual. The first patient had twice survived LMCA occlusion; the second also had right(More)
OBJECTIVE ECG diagnosis of myocardial infarction after cardiac surgery is associated with major pitfalls and enzyme diagnosis is interfered by unspecific elevation unrelated to permanent myocardial injury. Sustained release of troponin-T is a marker of permanent myocardial injury if renal function is maintained. However, early identification of(More)
OBJECTIVE A major assumption in cardiovascular medicine is that Q-waves on the electrocardiogram indicate major myocardial tissue damage. The appearance of a new Q-wave has therefore been considered the most reliable criterion for diagnosis of perioperative myocardial infarction (PMI) in cardiac surgery. In a study, originally intended to evaluate(More)
BACKGROUND AND AIMS OF THE STUDY An in vivo method for testing hemocompatibility of materials used in mechanical heart valves was developed. METHODS Discs of test materials were glued to specially designed plastic (Delrin) buttons and implanted into the superior and inferior venae cavae of sheep through a right thoracotomy. The button and disc had such(More)
A clinical series of acute aortic dissections is presented. Twenty cases were of type A and 10 of type B. Acute severe chest pain was common, in type A also blood pressure difference between the arms and aortic regurgitation. The diagnosis was established by echocardiography, computerized tomography and/or aortography. Antihypertensive therapy was(More)
Primary idiopathic chylopericardium is a rare entity with obscure etiology. In recent years, a few reports have been published where the lymphatic leak and fistula were identified by combined lymphangiography and computed tomography or intraoperative thoracic ductogram. Here we report a case occurring in a previously healthy 51 year old woman, to our(More)
The pulmonary formation of prostacyclin (PGI2), as reflected by the difference in concentration of pulmonary and systemic arterial radioimmunoassayed 6-keto-PGF1 alpha, was determined in six healthy waking subjects. The systemic arterial 6-keto-PGF1 alpha levels were low (less than or equal to 50 pg/ml), and no evidence of pulmonary formation and release of(More)
