1. Cardiac Resynchronization Therapy Optimization : Comparison and Evaluation of Non-invasive Methods
Abstract : The general purpose of this thesis was to investigate new cardiac resynchronization therapy (CRT) optimization techniques and to assess their reliability when compared to invasive measurements of left ventricular contractility (LV dP/dtmax).We first assessed whether cardiac output (CO) measured by trans-thoracic impedance cardiography could correctly identify the optimal interventricular (VV) pacing interval while using invasive measurements of LV dP/dtmax as reference.

2. Cardiac Resynchronization Therapy - Risk Stratification and Long-Term Outcome
Abstract : Heart failure is a condition that will affect 2-3% of the population. Around one third of the patients have a decreased LVEF and a widened QRS complex as a sign of ventricular dyssynchrony. CRT has emerged as a treatment that reduces morbidity, mortality and improve functional status in this population. READ MORE

4. Electromechanical effects and optimization modalities of cardiac resynchronization therapy
Abstract : Background and aims: Heart failure is a major health care problem, with high morbidity and mortality rates. In recent years, cardiac resynchronization therapy (CRT) has become an established additive treatment for patients with advanced heart failure, left ventricular (LV) dysfunction, and wide QRS complex.

5. The clinical value of total isovolumic time
Abstract : The objective of this thesis is to evaluate the use of Doppler echocardiography markers ofglobal dyssynchrony [total isovolumic time (t-IVT)] in the following 6 studies: 1) Its prognostic role in predicting cardiac events in patients undergoing CABG surgery,compared with conventional global systolic and diastolic measurements. 2) Its additional value in predicting six minute walk test (6-MWT) in patients with leftventricular (LV) ejection fraction (EF) .
