Filter by:Hypertrophic cardiomyopathy (Hypertrophic CardioMyopathy=HCM) remains a poorly understood disease with an assumption insufficiently codified. There is no data available in France on the profile of patients, diagnostic methods and assessment and therapeutic use. The purpose of this study is to establish a monitoring of patients with HCM (sarcomere of origin or not) in France (diagnosis, treatment)
The primary aim of this study will be to assess whether Biventricular pacing improves exercise capacity, and Quality of Life in patients with symptomatic drug resistant Non-Obstructive Hypertrophic Cardiomyopathy, using a Biventricular pacemaker.
Hypertrophic Cardiomyopathy is an inherited condition characterized by thickening (hypertrophy) of the heart muscle. Many patients who have this condition have a reduced ability to exercise because of breatlessness, which can in some cases be severe. This appears in most cases to be due to an impairment of the filling of the heart, especially on exercise this limits the amount of blood the heart is able to pump. Several factors may contribute to this slow filling of the heart, including (1) The heart contracts and relaxes in an incoordinate way (called 'dyssynchrony') which is inefficient, and (2) The filling of the main pumping chamber (the left ventricle) may be impeded by high pressure in the other ventricle(the right ventricle)- in other words the left ventricle is 'squashed' by the right ventricle. This is known as diastolic ventricular interaction. Although drugs can improve the filling of the heart and relieve symptoms, some patients remain very symptomatic despite these drugs. The mechanisms responsible for the filling abnormality in patients with Hypertrophic Cardiomyopathy are similar to those seen in the much more common condition known as Heart Failure. A special type of pacemaker technique called 'Biventricular Pacing' has been shown to markedly improve symtoms in patients with heart failure. This form of pacing has been shown to improve both 'dyssynchrony' ( incoordination) and 'ventricular interaction' (squashed left heart) in patients with Heart Failure. We propose that Biventricular pacing may similarly improve these abnormalities in patients with Hypertrophic Cardiomyopathy, resulting in an improvement of symptoms. The study will focus on patients with the condition who have severe symtoms despite being on optimal currently available drug therapy.
Compare data (structural and functional) obtained by transthoracic rest echocardiography and magnetic resonance imaging (with gadolinium) in 30 patients with hypertrophic cardiomyopathy
The aim of this study is the identification of familial congenital arrhythmogenic disorders and their clinical follow-up.
