Mitral annular dynamics are influenced by left ventricular load and contractility in an acute animal model
Persson, Robert Matongo; Aguilera, Hans Martin Dahl; Kvitting, Jon Peder Escobar; Grong, Ketil; Prot, Victorien Emile; Salminen, Pirjo-Riitta; Svenheim, Bård; Leiknes, Anita; Stangeland, Lodve; Haaverstad, Rune; Urheim, Stig (Journal article; Peer reviewed, 2023)The purpose of this study was to investigate the effects of loading conditions and left ventricular (LV) contractility on mitral annular dynamics. In 10 anesthetized pigs, eight piezoelectric transducers were implanted ... -
Short-term outcome after open-heart surgery for severe chronic rheumatic heart disease in a low-income country, with comparison with an historical control group: an observational study
Hauge, Ståle Wågen; Dalen, Havard; Estensen, Mette-Elise; Persson, Robert Matongo; Abebe, Sintayehu; Mekonnen, Desalew; Nega, Berhanu; Solholm, Atle; Farstad, Marit; Bogale, Nigussie; Graven, Torbjorn; Nielssen, Niels-Erik; Brekke, Hege Kristin; Vikenes, Kjell; Haaverstad, Rune (Journal article; Peer reviewed, 2021)Objectives Rheumatic heart disease (RHD) is a major burden in low-income and middle-income countries (LMICs). Cardiac surgery is the only curative treatment. Little is known about patients with severe chronic RHD operated ...
