6. New Intraoperative Techniques to Improve Advanced Aortic Root Surgery
Sammanfattning : Study I: Thirteen patients underwent a modified Ross operation in which the free-standing pulmonary autograft was supported externally by a Dacron vascular prosthetic jacket (DVPJ). The tailor-made DVPJ prevented dilatation of the neo-aortic root significantly following a median follow-up of 47 months compared to a cohort of l3 matched patients undergoing conventional Ross operation.

7. Carbon dioxide de-airing in cardiac surgery
Sammanfattning : Background: The risks connected with the presence of air microemboli in open-heart surgery, have recently been emphasized by reports that their number is correlated with the degree of postoperative neuropsychological disorder. Insufflation of carbon dioxide (C02) into the chest wound is used in open-heart surgery to de-air the heart and great vessels. LÄS MER
8. Left ventricular filling during coronary artery bypass grafting
Sammanfattning : Left ventricular (LV) filling, determination of preload, right ventricular end-diastolic volumes, volume contributions during early (E) and atrial (A) phases of LV filling and mitral valve opening areas were studied in 75 patients scheduled for elective coronary artery bypass grafting (CABG). The purposes of the study were: (1) To evaluate changes in LV filling judged as peak velocity E/A ratios determined by Doppler transesophageal echocardiography during and in the early phase after CABG.

9. Infectious endocarditis, aspects on pathogenesis, diagnosis and prognosis
Sammanfattning : The incidence of infectious endocarditis (IE) is estimated to 5.9/100.000 inhabitants and year. In recent years there has been an improvement in prognosis mainly due to more sensitive echocardiographic methods and surgery in the acute phase of the infection. LÄS MER
10. Splanchnic circulation in cardiac surgery
Sammanfattning : The studies addressed different techniques of monitoring hepatic and splanchnic blood flow (SBF) during open heart surgery. Calculations of gastric mucosal pH (pHi) using tonometry was performed in 72 patients, and the effect of dopaminergic stimulation on pH1 was studied in 33 patients. LÄS MER
