BACKGROUND Adult patients with congenital heart disease (CHD) usually find their exercise capacity satisfactory. However, objective evaluation is important for diagnostic and prognostic purposes. The aim of this study was to evaluate exercise capacity using cardiopulmonary exercise tests and measurement of serum B-type natriuretic peptide (BNP) levels in(More)
BACKGROUND Functional mitral regurgitation (FMR) is known to contribute to a poor prognosis in patients with heart failure (HF). Current guidelines do not recommend cardiac surgery in patients with FMR and impaired ejection fraction due to the high procedural risk. Percutaneous techniques aimed at mitral valve repair may constitute an alternative to(More)
INTRODUCTION Ebstein's anomaly is defined as the significant apical displacement of the part of the tricuspid valve causing significant tricuspid regurgitation and reduction of the functional right ventricle. The aim of the study was to evaluate exercise capacity with cardiopulmonary stress testing and to determine plasma BNP levels in adults with Ebstein's(More)
The aim of the study was to investigate, in adult patients after successful repair of aortic coarctation, potential relationships between B-type natriuretic peptide levels and exercise capacity and the following factors: arterial hypertension, residual stenosis of the ascending aorta, and age at the time of surgery. The study group comprised 74 patients (45(More)
BACKGROUND Structural heart disease, including valvular disease as well as congenital defects, causes important alterations in heart anatomy. As a result, individualised planning for both surgical and percutaneous procedures is crucial for procedural optimisation. Three dimensional (3D) rapid prototyping techniques are being utilised to aid operators in(More)
Adult patients after surgical repair of Fallot's tetralogy usually present with satisfactory exercise capacity years after the original procedure, though they never tolerate as high levels of exercise as their healthy counterparts. The aim of the study was to assess exercise capacity with cardiopulmonary stress test and BNP levels in adult survivors of(More)
BACKGROUND Total surgical repair of tetralogy of Fallot is usually associated with a favourable long-term outcome. However, complications or consequences of the defect such as dilatation of aortic root and aortic regurgitation are present in some patients. AIM To assess the prevalence of aortic regurgitation in relation to the timing of surgery and(More)
BACKGROUND Despite effective repair of coarctation of the aorta (CoAo), arterial hypertension (AH) and early coronary artery disease that may result in heart failure. The aim of the study was to evaluate exercise capacity by a cardiopulmonary exercise test in patients after of CoAo repair, and to determine relations between these parameters and the presence(More)
BACKGROUND In spite of surgical correction, arterial hypertension may persist in a significant proportion of patients with aortic coarctation. AIM To asses arterial blood pressure (BP) and left ventricular (LV) mass and function in adult patients who underwent surgical repair of aortic coarctation. METHODS The study group consisted of 56 patients (27(More)
BACKGROUND In patients with chronic heart failure (CHF) QRS prolongation is a frequent finding and is related to increased morbidity and mortality. It is not clear if prolonged QRS in CHF of ischaemic origin (CAD) represents the same severity of the syndrome as in non-ischaemic (non-CAD) cardiomyopathy. AIM To assess the relationship between QRS duration(More)
