Cost conscious care: preoperative evaluation by a cardiologist prior to low-risk procedures.

Background: Preoperative testing before low-risk procedures remains overutilised. Few studies have looked at factors leading to increased testing. We hypothesised that consultation to a cardiologist prior to a low-risk procedure leads to increased cardiac testing. Methods and results: 907 consecutive patients who underwent inpatient endoscopy/colonoscopy at a single academic centre were identified. Of those patients, 79 patients (8.7%) received preoperative consultation from a board certified cardiologist. 158 control patients who did not receive consultation from a cardiologist were matched by age and gender. Clinical and financial data were obtained from chart review and hospital billing. Logistic and linear regression models were constructed to compare the groups. Patients evaluated by a cardiologist were more likely to receive preoperative testing than patients who did not undergo evaluation with a cardiologist (OR 47.5, (95% CI 6.49 to 347.65). Specifically, patients seen by a cardiologist received more echocardiograms (60.8% vs 22.2%, p<0.0001) and 12-lead electrocardiograms (98.7% vs 54.4%, p<0.0001). There was a higher rate of ischaemic evaluations in the group evaluated by a cardiologist, but those differences did not achieve statistical significance. Testing led to longer length of stay (4.35 vs 3.46 days, p=0.0032) in the cohort evaluated by a cardiologist driven primarily by delay to procedure of 0.76 days (3.14 vs 2.38 days, p=0.001). Estimated costs resulting from the longer length of stay and increased testing was $10 624 per patient. There were zero major adverse cardiac events in either group. Conclusion: Preoperative consultation to a cardiologist before a low-risk procedure is associated with more preoperative testing. This preoperative testing increases length of stay and cost without affecting outcomes.

Unrepaired tetralogy of fallot with major aortopulmonary collateral arteries in an adult patient.

Tetralogy of Fallot is characterized by a ventricular septal defect, a large, overriding aorta, subpulmonic stenosis, and right ventricular hypertrophy. These lesions can be associated with abnormal development of the pulmonary vasculature. This can include peripheral pulmonic stenosis, discontinuous pulmonary arteries, anomalous pulmonary venous return, and the development of aortopulmonary collateral vessels. Aortopulmonary collateral vessels develop to supply underperfused areas of the pulmonary bed and pose a unique and challenging problem at the time of surgical repair, which involves closure of the ventricular septal defect, relief of right ventricular outflow tract obstruction, maintenance of pulmonary valve competency when possible, and establishment of laminar pulmonary blood flow to all segments of the pulmonary bed. We describe a 36-year-old man with unrepaired tetralogy of Fallot with distinctive aortopulmonary collaterals, who underwent complete surgical repair with good outcome. Two-dimensional echocardiogram, cardiac magnetic resonance imaging, and cardiac catheterization each provided vital details allowing a stepwise approach to defining his unique anatomy for surgical correction.

Maternal arrhythmia: a case report and review of the literature.

UNLABELLED: Pregnant patients with maternal arrhythmias can be challenging and difficult to treat. Medication choices may be limited in patients who are pregnant. Pregnancy carries with it a unique and complex physiology, coupled with fetal concerns. We describe a pregnant patient with an arrhythmia to illustrate treatment thought process and options. We also present a comprehensive review of the literature in regard to treatment of maternal arrhythmias and their potential adverse fetal and maternal outcomes. These treatments include antiarrhythmic medications, electrical cardioversion, and radiofrequency ablation. Antepartum and intrapartum monitoring will also be addressed along with delivery planning and postpartum considerations. The most important aspect in treating these patients is the use of a multidisciplinary approach. The decision of what therapy to use must be addressed on a case-by-case basis with special attention to the patient's individual issues and concerns. TARGET AUDIENCE: Obstetricians and gynecologists, family physicians, emergency room physicians LEARNING OBJECTIVES: After completion of this educational activity, the obstetrician/gynecologist should be better able to assess and council patients on the risks and complications of maternal arrhythmias in pregnancy. Evaluate the current treatment options available for health care providers caring for pregnant patients with maternal arrhythmia, and manage the antepartum course, labor, and delivery in these patients.
