1. Left atrial function in health and disease
Abstract : The Objectives of this thesis are:1) To study possible atrial interaction in patients with right and left ventricular outflow tract obstruction due to significant pulmonary (PS) and aortic valve stenosis (AS), respectively.2) To assess left atrial (LA) intrinsic myocardial function and its relationship to indirect measures of left ventricular (LV) filling pressures in patients with paroxysmal atrial fibrillation (PAF).

2. Mean systemic filling pressure - from Guyton to the ICU, and back again
Abstract : Introduction: Mean systemic filling pressure (MSFP) is the equilibrated vascular pressure at zero flow. Venous return (VR) driving pressure (VRdP) is the difference between MSFP and right atrial pressure (RAP). READ MORE

3. Secundum atrial septal defect in the adult. Clinical, haemodynamic and electrophysiological aspects
Abstract : Atrial septal defect (ASD) is the most common congenital heart malformation diagnosed in adult life. In this thesis important clinical, haemodynamic and electrophysiological aspects of ASD in the adult are explored. READ MORE

4. Insights into left atrial response to pressure and volume overload
Abstract : The general purpose of this thesis is to establish the ability of Speckle Tracking Echocardiography (STE) in assessing left atrial (LA) response to pressure and volume overload respectively in aortic stenosis (AS) and mitral regurgitation (MR), and to evaluate its accuracy in predicting LA and right ventricular (RV) fibrosis in patients with end-stage heart failure (HF) undergoing heart transplantation (HTx).I demonstrated that assessment of left ventricular (LV) long axis systolic velocity and amplitude of excursion is more sensitive than simple determination of ejection fraction (EF) for revealing the beneficial impact of MR surgery on overall LV systolic performance.

5. The important role of left atrial function parameters in clinical practice
Abstract : The aim of this thesis is to evaluate the role of left atrial function in clinical practice based on the following studies:1) Determining left atrial (LA) structure and myocardial function measurements that predict pulmonary capillary wedge pressure (PCWP).2) Identifying predictors of exercise capacity in patients with HFpEF and right ventricle (RV) dysfunction.
