“…However, the success of the therapy lies in optimized individual programming of stimulation parameters to maintain atrial ventricular synchrony. The maintained benefit in functional status of sequential atrial ventricular pacing has been demonstrated in long series of cases (median follow-up of 8.5 years) [23]. Lenarczyk et al [24] shows in his preliminary study a decrease in outflow tract gradient and improvement of the functional status.…”

Cardiomyopathies are heart diseases involving high risk of heart failure and sudden cardiac death. In this chapter, we review the use of electrical devices (cardiac resynchronization therapy and implantable cardioverter defibrillator) to reduce the progression of heart failure and prevent arrhythmogenic sudden death in patients affected with these pathologies. The future of these therapies is a more appropriate indication for primary prevention of sudden death (defibrillator) and treatment of heart failure in a broader spectrum of patients (resynchronization).

“…The comparison between surgical myotomy-myectomy and alcohol septal ablation (ASA) is most interesting, whereas DDD pacing is marginalized for rare indication. However in Spanish center [ 48 ] beneficial effect has been observed in 18-year-long follow-up study on DDD pacing. Sequential pacing in selected patients with obstructive HCM improves functional class and reduces dynamic gradient and mitral regurgitation immediately after pacemaker implantation and at final follow-up [ 48 ].…”

Dynamic (latent or/and labile) obstruction of left ventricular outflow (LVOT) was recognized from the earliest clinical descriptions of hypertrophic cardiomyopathy (HCM) and has proved to be a complex phenomenon, as well as arguably the most audible (“visible”) pathophysiological hallmark of this heterogeneous disease. The aim of the current review is focused on two novel issues in a subgroup of obstructive HCM. Firstly, the important methodological problem in HCM is the examination of a subgroup of patients with nonobstructive hypertrophy in resting conditions and hard, but possible provoking obstruction. Recently, investigators have proposed physiological stress test (with double combined stimuli) to disclose such type of patients. The upright exercise is described in the ESC guideline on hypertrophic cardiomyopathy from 2014 and may appear as a candidate for gold standard provocation test. The second novel area of interest is associated with elevated level of signaling biomarkers: hypercoagulation, hemolysis, acquired von Willebrand 2A disease, and enhanced oxidative stress. The accelerated and turbulent flow within narrow LVOT may be responsible for these biochemical disturbances. The most recent advances in the treatment of obstructive HCM are related to nonpharmacological methods of LVOT gradient reduction. This report extensively discusses novel methods.
