BACKGROUND AND AIM OF THE STUDY Diagnostic procedures continue to contain much hidden information that may substantially improve the understanding of the mechanisms of aortic valve disease and its treatment planning. The study aim, using transesophageal echocardiography (TEE), was to describe in detail the anatomical and physiological properties of the(More)
AIMS Knowledge of longitudinal left and right ventricular (LV and RV) function after transcatheter aortic valve implantation (TAVI) is scarce. We hypothesized that the longitudinal systolic biventricular function in aortic stenosis (AS) patients is affected differently by TAVI and surgical aortic valve replacement (SAVR). METHODS AND RESULTS Thirty-three(More)
BACKGROUND Risk factors for postoperative heart failure (PHF) have not been specifically studied in valve surgery although it has been acknowledged that patient variables may have a more profound influence on postoperative outcome than valve-related factors. METHODS All patients undergoing isolated aortic valve replacement for aortic stenosis from January(More)
BACKGROUND Timing of surgery in aortic regurgitation (AR) is important. Exercise testing is recommended upon uncertainty about functional limitations but reports on cardiopulmonary exercise testing (CPET) in populations with pure chronic AR are scarce. METHOD Twenty-eight patients referred for surgery because of chronic AR (13 in NYHA I, 10 in NYHA II and(More)
OBJECTIVES To evaluate longitudinal left and right ventricular function (LVF and RVF) after transcatheter aortic valve implantation (TAVI) as compared to surgical aortic valve replacement (SAVR) and LVF and RVF after TAVI by the transfemoral (TF) or transapical (TA) approach. BACKGROUND Knowledge about differences in recovery of LVF and RVF after TAVI and(More)
BACKGROUND The aim of this study was to evaluate if left ventricular (LV) systolic function by tissue Doppler echocardiography at rest and during exercise preoperatively could predict postoperative LV function and thereby be useful in the timing of aortic valve surgery in patients with severe aortic regurgitation. METHODS In 29 patients (median age, 59(More)
The myocardium is unable to regenerate itself after infarct, resulting in scarring and thinning of the heart wall. Our objective was to develop a patch to buttress and bypass the scarred area, while allowing regeneration by incorporated cardiac stem/progenitor cells (CPCs). Polycaprolactone (PCL) was fabricated as both sheets by solvent casting, and fibrous(More)
There are relatively few studies on female athletes examining cardiac size and function and how these measures relate to maximal oxygen uptake (VO2max). When determining sports eligibility, it is important to know what physiological adaptations and characteristics may be expected in female athletes, taking body and cardiac size into account. The purposes of(More)
BACKGROUND Most studies on cardiac function in athletes describe overall heart function in predominately male participants. We aimed to compare segmental, regional and overall myocardial function and synchrony in female endurance athletes (ATH) and in age-matched sedentary females (CON). METHODS In 46 ATH and 48 CON, echocardiography was used to measure(More)
Exercise testing is underutilized in patients with valve disease. We have previously found a low physical work capacity in patients with aortic regurgitation 6 months after aortic valve replacement (AVR). The aim of this study was to evaluate aerobic capacity in patients 4 years after AVR, to study how their peak oxygen uptake (peakVO(2)) had changed(More)
