Ablation of left ventricular epicardial outflow tract tachycardia from the distal great cardiac vein.
OBJECTIVES The purpose of this study was to examine the feasibility and safety of ablation of idiopathic outflow tract ventricular tachycardia (OTVT) from the distal ramifications of the coronary sinus (CS). BACKGROUND A significant minority of patients presenting with idiopathic OTVT have an epicardial focus, the standard approach to which involves ablation from within one of the aortic valv...
متن کاملFunctional Characteristics of the Left Ventricular Inflow and Outflow Tracts.
• The heart chambers contract sequentially and any significant alteration in spread of the electrical activity may bring about a change in sequence. While recording contractile force from multiple sites on a single ventricle, it was noted that different portions of the ventricular myocardium showed consecutive onset of systole. Puff employed high-speed cinematography to study changes in ventric...

متن کاملResveratrol Suppresses Cardiac Renin Angiotensin System in the Late Phase of Left Ventricular Hypertrophy
Background and objectives: Resveratrol(3,5,4′-trihydroxy-trans-stilbene) is a natural polyphenole phytoalexin which exerts potential cardioprotective effects, but the cellular and molecular mechanisms responsible for these effects are still unknown. Cardiac renin angiotensin system (RAS) over-activation plays an important role in pathogenesis of left ventricula...
متن کاملRadiofrequency catheter ablation of premature ventricular contractions originating in the right ventricular outflow tract.
OBJECTIVES To evaluate if radiofrequency catheter ablation is an effective procedure for the treatment of right ventricular outflow tract premature ventricular contractions (RVOT-PVC) and ascertain if it results in an improvement of symptoms. METHODS A prospective study with 30 consecutive patients (mean age 40 +/- 13 years, 25 females), with no apparent structural cardiopathy, with very freq...
