[How I study the assessment of the risk of sudden death in Wolff-Parkinson-White syndrome].

The identification of a WPW impose to evaluate the potential risk of sudden cardiac death. The risk depends on the duration of the refractory period of the accessory pathway. If the preexcitation disappears when the patient is stressed on a treadmill, there is no risk of sudden death. If it does not, an electrophysiological study will have to be performed to measure the refractory period of the accessory pathway. If a risk of sudden death is present (refractory period < 220 ms), the accessory pathway has to be ablated using radiofrequency.

[The treatment of heart decompensation using angiotensin converting enzyme inhibitors. Pharmaco-economic aspects].

Heart failure is a challenge for modern cardiology, Common, disabling, lethal, this condition represents a major economic burden for Public Health. When patients with heart failure receive an ACE inhibitor in addition to diuretics and digoxin, they have fewer symptoms, are less frequently admitted to hospital and live longer. The currently available pharmaco-economic analyses support the use of ACE inhibitors in heart failure.

[Follow-up of patients treated by amiodarone].

Amiodarone is a highly effective antiarrhythmic agent. Its iodine content and tissue accumulation are however responsible for various side effects. In this article, we review the various amiodarone related side effects and propose a monitoring chart for patients treated by this specific agent.

Atrial flutter: historical background.

For five decades, the mechanism of atrial flutter remained controversial, with protagonists and antagonists of circus movement versus ectopic focus theories. The development of clinical electrophysiology in the 1970s and the observations made by many authors in various canine heart models supported the concept of atrial flutter as a reentrant wave confined to the right atrium. It was established that, in the common type of atrial flutter, the activation wavefront proceeds in a cranial direction over the right atrial septum and descends on the right atrial free wall in the caudal direction. A zone of slow conduction was identified inferiorly and posteriorly in the right atrium, target of the modern ablative techniques. The history of atrial flutter clearly illustrates the bidirectional flow of information and the mutual stimulation between the basic and the clinical levels, leading both to a better understanding of the nature of the arrhythmia and to new therapeutic approaches.

Variability in estimation of coronary dimensions from 6F and 8F catheters.

To investigate the suitability of diagnostic 6F catheters for coronary angiographic measures in the clinical setting, we determined the relative accuracy and reproducibility of the measures obtained with these catheters as scaling devices in 59 stenoses. Comparison was made with duplicate injections, obtained before angioplasty, using an 8F guiding catheter as scaling device. Intra- and interobserver variability was evaluated in 15 stenoses. The coefficient of variation averaged 18.3% for the minimal lumen diameter, 10.4% for the percent stenosis, and only 7.4% for the reference diameter. Reproducibility of angiographic measures done with the 6F catheter was similar to that obtained with the 8F catheter, although accuracy was lower with the 6F for the measurement of reference diameter. Thus, quantitative coronary angiography (QCA) measures derived from routine diagnostic angiograms may be suitable for determination of reference diameter, allowing enough precision for determination of the size of a coronary device for intervention, but these measures may lack accuracy for precise determination of minimum diameter and percent stenosis, making their use questionable in studies looking at individual changes in coronary stenosis dimensions.

Percutaneous balloon pericardiotomy: a case report and analysis of mechanism of action.

A 33-year-old man with acquired immunodeficiency syndrome (AIDS) and cardiac tamponade underwent percutaneous balloon pericardiotomy. To elucidate the pathway of fluid elimination, at the end of the procedure, we injected methylene blue into the pericardial space. Contrary to previous belief, we found no blue discoloration of the pleural fluids, and thus we postulate that most of the fluid was eliminated by peritoneal resorption.
