Surgical ventricular restoration-meta-analysis of observational studies.

Background: Technique of surgical ventricular restoration (SVR) may impact its outcomes. Therefore, we conducted a meta-analysis of studies on SVR performed by using different techniques and studied outcomes.

Methods: Scientific databases were searched for studies on SVR.

Is programmed electrical stimulation mandatory for recognition of ventricular arrhythmogenicity in heart failure?

Ischemic cardiomyopathy often presents with advanced heart failure necessitating an intensive multidisciplinary approach to management. These patients constitute a very difficult population presenting with angina and ventricular tachyarrhythmias sometimes presenting as sudden cardiac death. In those patients presenting with spontaneous ventricular tachyarrhythmias, treatment with automated intracardiac defibrillator implantation has a significant mortality benefit.

Optimization of surgical ventricular restoration by in-silico simulations.

Objective: A hypothesis on left ventricular aneurysms states that there is better preservation of contractile myocardium when the aneurysm geometry is rectangular as opposed to circular. Pre-surgical planning of surgical ventricular restoration was performed on the basis of this hypothesis.

Methods: The intraventricular patch used to exclude scarred or aneurysmal myocardium remains akinetic, hence it was used to define aneurysm geometry as circular or rectangular.

Lessons from a mathematical hypothesis - modification of the endoventricular circular patch plasty.

Objective: Surgical ventricular restoration has been the bailout therapy for end-stage heart failure due to ischemic cardiomyopathy in patients not suitable for cardiac transplantation. The recently concluded STICH trial has stated that surgical restoration of the left ventricle does not benefit this subgroup of patients clinically as compared with revascularization alone. The reasons for failure of this trial are multifactorial.
