Percutaneous pulmonary valve implantation was introduced in the year 2000 as a nonsurgical treatment for patients with right ventricular outflow tract dysfunction. Between September 2000 and February 2007, 155 patients with stenosis and/or regurgitation underwent percutaneous pulmonary valve implantation. This led to significant reduction in right ventricular systolic pressure (from ...

BACKGROUND: For allocation of primary ICD-therapy, a possible lower limit of inclusion criteria--defining overly advanced heart failure--is less well investigated. Also, a multi-variable approach to stratification beyond ejection fraction (LVEF) appears warranted. We examined whether adding a selection limit of peak VO(2) <or= 14 ml/kg/min to LVEF <or= 20% improves ...
Vanerio Gabriel - - 2008
INTRODUCTION: Long-term prognosis after pacemaker implant depends on numerous variables, particularly structural heart disease. There is evidence that apical stimulation could favor the development of heart failure and, therefore, influence mortality. Other right ventricular pacing sites have been studied, for example the outflow tract, but no reports regarding long-term clinical ...

It is well known that by improving mitochondrial bioenergetics, Coenzyme Q10 improves the systolic function in heart failure. The aim of this study was to see whether it benefits the diastolic dysfunction in hypertrophic cardiomyopathy (HCM) cases since diastolic relaxation also requires energy like the systole. 200 mg/day of CoQ10 ...
