Bifocal Stimulation in Patient with Congenitally Corrected Transposition of Great Vessels

Congenitally corrected transposition of the great vessels (CCTGV) is a rare congenital heart defect associated with multiple cardiac morphological abnormalities and conduction defects. Complete atrioventricular (AV) block occurs in 30% of patients and it may be present at birth or develop later with a rate of 2% per year; moreover, a systemic right ventricle is frequently characterized by heart failure in adult life. We used a bifocal cardiac stimulation for a young woman affected by CCTGV and atrioventricular Mobitz 2 and 2:1 block, considering structural, anatomic condition, and the high rate of pacing she underwent.

Cardiopulmonary Exercise Testing in Patients with Chronic Heart Failure: Prognostic Comparison from Peak VO2 and VE/VCO2 Slope

Background: Cardiopulmonary exercise testing with ventilatory expired gas analysis (CPET) has proven to be a valuable tool for assessing patients with chronic heart failure (CHF). The maximal oxygen uptake (peak V02) is used in risk stratification of patients with CHF. The minute ventilation-carbon dioxide production relationship (VE/VCO2 slope) has recently demonstrated prognostic significance in patients with CHF. Methods: Between January 2006 and December 2007 we performed CPET in 184 pts (146 M, 38 F, mean age 59.8 ± 12.9 years), with stable CHF (96 coronary artery disease, 88 dilated cardiomyopathy), in NYHA functional class II (n.107) - III (n.77), with left ventricular ejection frac…
