[Theory concerning a possible mechanism of displacement of intracavitary electrode catheters].

Reference is made to three cases in proposing an explanation for the shifting of endocavitary catheters, namely traction of the lead attached to the lower side of the stimulator owing to movement of the apparatus, resulting in displacement of the tip. It is pointed out that the intravasal length of the displaced catheter is markedly decreased in 3 out of 4 cases. Attention is therefore drawn to the importance of the relation between catheter and stimulator in causing a high percentage of the case of displacement observed.

[Theory of training and quality of safety in health].

This article aims to define the concept of security, particularly in relation to concepts of risk, error, danger and adverse events. The authors go on to analyse the latest theory of adult training, applying it to healthcare safety whilst recognising that this is a complex facility. By using tools such as guidelines and risk management, the authors propose a new kind of corporate culture that enables certain initiatives, such as clinical governance and therefore learning organisation, to develop. This strategic organisation the company allows vital knowledge and experience, which lead to problem-solving and an increased guarantee of security for both internal and external clients, to become the common knowledge and property of the company as a whole and of all who operate in and around it.

[Serial Doppler echocardiography follow-up studies in the postoperative evaluation of severe pulmonary hypertension following surgery for mitral and mitral-aortic defects].

Between January 1987 and December 1991 26 patients with mitral and mitro-aortic disease and severe pulmonary hypertension (> or = 60 mmHg) were subjected to surgery. In 22 patients we have studied systolic pulmonary pressures by echocardiography-Doppler examination at 3-6 and 12 months from surgery. We noticed a decrease in pulmonary pressure values in all patients within 3 months from surgery (mean values pre-op 75 +/- 12.14; mean values post-op 42 +/- 11.26); within 6 months from surgery physiological values were reached in all patients (mean values 35 +/- 5.3). We have further divided patients in two subgroups: group A with pulmonary pressures superior or equal to 80 mmHg (mean values 90.00 +/- 17.32) and group B With pressure values between 60 and 79 mmHg (mean values 69.12 +/- 3.64). The first Doppler evaluation demonstrated a greater decrease in group B (mean values 37.8 +/- 6.5 versus 57 +/- 12.4); at the second control there was no statistically significant difference between the two groups (group A 36 +/- 5.48, group B 33.33 +/- 5.37). The only two operative deaths were caused by the pre-op cardiogenic shock. There has been no late mortality among survivors, 22 in NYHA Class I and 2 in NYHA Class II. Pulmonary hypertension decreases after surgery independently of the adopted procedure (replacement, repair or lysis).
