[Mejora progresiva de los umbrales de captura auricular y ventricular, detección e impedancias en los cables de estimulación epicárdica en adultos jóvenes que se someten a conversión de Fontan].

Objectives: Patients with univentricular hearts who require permanent pacing systems typically require placement of epicardial leads. It is frequently difficult to find a position with good thresholds due to epimyocardial fibrosis or fat. The goal of the study is to assess the progression of capture thresholds (CT), sensing parameters (P waves and R waves), and impedances (imp) of steroid eluting epicardial pacing leads in young adults who underwent Fontan conversion and a pacemaker implant.

[Drug-induced ventricular dissynchrony and tachycardiomyopathy in a newborn].

Ventricular dysfunction secondary to electrical and mechanical dyssynchrony in chronic right ventricular apical pacing is a well-recognized complication. There are no previous reports of pharmacologically induced dyssynchrony. A 10-day old infant with incessant supraventricular tachycardia was admitted to the neonatal intensive care unit.

Experience using propranolol for the management of supraventricular tachycardia in patients younger than 1 year.

Objective: To assess the results and adverse events of propranolol therapy in infants younger than 1 year with supraventricular tachycardia.

Population And Methods: Infants younger than 1 year with documented supraventricular tachycardia who received oral treatment and prophylaxis with propranolol. Sex and age, associated congenital heart disease, ventricular preexcitation in the base line electrocardiogram, on-treatment recurrence, and adverse events were analyzed.

The HAV pattern in pediatric patients with atrioventricular node reentrant tachycardia.

Objectives: The purpose of this study is to assess the prevalence of a His-Atrial-Ventricular (HAV) pattern, i.e. the atrial electrogram following the His bundle -HB- electrogram and preceding the ventricular one, on the catheter placed in the His position in pediatric patients during typical atrioventricular node reentry (AVNRT).

The role of hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) in the treatment of peritoneal carcinomatosis in recurrent ovarian cancer.

Background And Objectives: Peritoneal carcinomatosis in women frequently has an ovarian origin. Hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) along with radical surgery/peritonectomy could present a new therapeutic approach with curative intention. The purpose of this research is to evaluate the role of the administration of HIPEC.

[Haemostatic and inflammation markers in acute coronary syndromes and its relationship with adverse cardiovascular events].

Background: In acute coronary syndromes (ACS) interaction among several haemostatic (S and C protein, antitrhombin Ill, C protein resistance, plasminogen, alpha 2-antiplasmi and inflammatory factors (white cell blood count, fibrinogen, reactive C protein) could have association with recurrent thrombosis and recurrence ischemia, reinfarction, shock and cardiovascular mortality.

Methods: Prospective, controlled, with a six-year follow-up trial. END-POINT: Prove in acute phase and in a follow-up association among inflammatory, coagulation and fibrinolysis markers with cardiovascular adverse events.

Radical surgery-peritonectomy and intraoperative intraperitoneal chemotherapy for the treatment of peritoneal carcinomatosis in recurrent or primary ovarian cancer.

Background And Objectives: Advanced ovarian cancer typically spreads in a diffuse intra-abdominal fashion. This characteristic suggests that combined radical surgery and intraperitoneal chemotherapy may be a useful treatment procedure. The purpose of this study was to review patients submitted to surgical debulking and hyperthermic intraoperative intraperitoneal chemotherapy (HIIC) and to evaluate the potential prognostic survival factors for advanced epithelial ovarian cancer in our center.
