    ObjectivesTo determine the safety and efficacy of a standardized approach to the use of an endovascular coronary sinus (CS) catheter during minimally invasive cardiac surgery.DesignCase series.SettingUniversity hospital.ParticipantsPatients undergoing mitral and/or tricuspid valve surgery using a minimally invasive cardiac surgery approach.InterventionsAn endovascular CS catheter was placed to enable the administration of retrograde cardioplegia using transesophageal echocardiography (TEE), fluoroscopy, and CS pressure measurements.Measurements And Main ResultsData were collected from 96 patient records. A total of 95 (99.0%) endovascular coronary sinus catheters were positioned. The mean time to insert the catheter into the sinus ostium under TEE guidance was 6.3 ± 8.4 minutes. Confirmation of adequate positioning with fluoroscopy took an average of 9.1 ± 10.6 minutes for a mean total procedure time of 16.1 ± 14.1 minutes. Successful positioning, as defined by the ability to generate a perfusion pressure in the CS greater than 30 mmHg during surgery, was achieved in 87.5% of cases. During positioning, ventricularization of the CS pressure curve was observed in 86.0% of cases. The presence of ventricularization was associated with an increase in positioning success (odds ratio = 15.8; 95% confidence interval, 3.713-67.239). One patient developed extravasation of contrast agent after CS catheter placement, without evidence of CS rupture.ConclusionsEndovascular CS catheter insertion can be performed with a high rate of success for positioning and a low complication rate. During positioning, obtaining ventricularization is associated with an increased success rate.Crown Copyright © 2010. Published by Elsevier Inc. All rights reserved.
