Abstract

PURPOSE:  Single ventricle physiology occurs when one of the two ventricles is sufficiently small that a series circuit is incompatible with survival. Traditionally, all patients with single ventricle physiology undergo cardiac catheterization before palliative surgical correction . Cardiac catheterization carries small but appreciable risks, including arrhythmias, vascular damage, radiation exposure, patient discomfort, and parental anxiety. Additionally, in the current atmosphere of cost containment, the role of preoperative cardiac catheterization versus echocardiography assessment should be reevaluated. We postulate that by solely using commonly acquired echocardiographic information, patients with single ventricle physiology can undergo palliative surgical correction with bi- Glenn or Fontan procedure and safely avoid preoperative cardiac catheterization.

METHODS:  We retrospectively reviewed the medical records of all the patients who underwent biGlenn and Fontan procedure from April 1995 through June 2003 at the Intensive Care Unit of the Centro Cardiovascular de Puerto Rico y del Caribe. Inclusion criteria included all children with univentricular physiology who had a complete preoperative echocardiogram performed within two weeks of surgery and who underwent palliative surgical corrections in the selected study period.

RESULTS:  A total of 37 patients were identified to meet the criteria. The most common preoperative diagnosis was Tricuspid Atresia (n=15), followed by Single Ventricle (n=13) and Pulmonary Atresia (n=9). There was no discordance between echocardiography and surgical findings. Bi-Glenn was performed in thirty-two patients. One patient of the biGlenn group died for an overall group survival of 96.8% . Twenty patients underwent Fontan procedure. Seventeen patients had undergone prior Glenn shunt. The overall group survival was 100%.

CONCLUSION:  Echocardiography is a valuable diagnostic tool if performed after a careful physical examination. It can provide the information needed for a complete and accurate diagnosis of congenital heart diseases.

CLINICAL IMPLICATIONS:  We conclude that morbidity and mortality after single ventricle palliative correction is not affected by echocardiography as the only preoperative assessment tool and that routine use of cardiac catheterism with its implicated complications and higher costs may be avoided.
