Clinical outcomes of pulsatile and non-pulsatile mode of perfusion.

A longstanding debate remains over whether or not pulsatile flow provides better perfusion during cardiopulmonary bypass (CPB). This paper provides a guide for clinical investigation, as well as current laboratory and clinical evidence concerning pulsatile and non-pulsatile perfusion. This evidence is in the form of in vitro and in vivo experiments and clinical trials.

Benefits of pulsatile perfusion on vital organ recovery during and after pediatric open heart surgery.

Controversy continues concerning the utilization of pulsatile flow during cardiopulmonary bypass (CPB) procedures with regard to improved patient outcomes. We evaluated 215 consecutive pediatric patients undergoing open heart surgery for repair of congenital heart disease who were prospectively entered into the study and randomly assigned to either the pulsatile perfusion group (group P, n = 151) or the nonpulsatile perfusion group (group NP, n = 64). All patients received identical surgical, perfusional, and postoperative care.

Postoperative prophylactic peritoneal dialysis in neonates and infants after complex congenital cardiac surgery.

Peritoneal dialysis after complex congenital cardiac surgery was introduced to a group of neonates and infants (n = 756; age, 0 to 1 year) between May 1993 and December 2005. Indications of peritoneal dialysis were determined as well as methods, prolonged dialysis, and its outcomes. Demographic characteristics, preoperative risk factors, intraoperative variables, and postoperative complications were compared in 756 cases with ages below 1 year.

Symptomatic lipoma in the interventricular septum.

Cardiac lipomas, which are benign nonmyxomatous neoplasms of the heart, are rare and among those least often encountered. Because they normally cause no symptoms, diagnosis is often purely accidental. We report the case of a 24-year-old woman who presented with palpitations of recent onset and was found to have a lipoma attached to the left side of the interventricular septum (IVS).

Shprintzen (velo-cardio-facial) syndrome: a rare case.

Shprintzen syndrome (velo-cardio-facial, VCFS) is a very rare morbid entity, seen in either familial or sporadic forms, with major clinical findings such as facial dysmorphism, cleft palate, cardiovascular (especially conotruncal-anomalies), mild/moderate mental retardation, or, more commonly, observed learning difficulty. Tendency to behavioral disorders and bipolar schizophrenic diseases may be present in these cases. Autosomal dominant inheritance has been reported.

Effects of pulsatile and nonpulsatile perfusion on vital organ recovery in pediatric heart surgery: a pilot clinical study.

The use of pulsatile flow during cardiopulmonary bypass (CPB) with regard to improved patient outcomes is controversial. We evaluated pulsatile perfusion in pediatric patients undergoing CPB in a clinical setting. Fifty consecutive pediatric patients undergoing open heart surgery for repair of congenital heart disease were prospectively entered into the study and randomly assigned to either the pulsatile perfusion group (group P, n = 25) or the nonpulsatile perfusion group (group NP, n = 25).

Sequence variations within the genes related to hemostatic imbalance and their impact on coronary artery disease in Turkish population.

Coronary artery disease (CAD) is reported to be associated with some genetic risk factors. Since identification of genetic risk factors for CAD in different ethnic groups is important for the development of new intervention and prevention programs, we investigated the association between the R353Q and -323ins10 polymorphisms in Factor VII gene, C677T mutation in MTHFR, Factor V Leiden and PT G20210A mutations and CAD in Turkish population. The promoter region of the PAI-1 gene was also screened by SSCA (single-stranded conformation analysis) using specifically designed primers.
