Abstract
Objective: This study investigated the clinician practices on perioperative anticoagulation in children with prosthetic mechanical heart valves who undergo elective surgeries.
Design: An online survey was administered to members of PediHeartNet. The survey consisted of multiple choice questions and clinical scenarios.
Outcome measures: The study described clinical practice patterns and variables that influence the clinicians' bridging anticoagulation decisions.
Results: Ninety-one respondents completed the survey; 68% were affiliated with university settings; 91% were pediatric cardiologists, and 49% had ≥10 years of experience in pediatric cardiology. Approximately one-half of the respondents (54%) independently provided perioperative anticoagulation management to their patients, while 46% utilized cardiac or hematology anticoagulation services. Resources that influenced bridging decisions included hematology experts (20%), American College of Chest Physicians guidelines (34%), and the clinicians' personal experience (56%). In planning for major surgeries, 47% of the respondents hospitalized patients for unfractionated heparin (UFH) and 46% prescribed outpatient low molecular weight heparin (LMWH). For minor surgeries, 58% hospitalized patients for UFH, 22% prescribed outpatient LMWH, and 17% opted out of bridging anticoagulation. Immediately after mitral valve replacement, 23% used bridging anticoagulation with UFH. When LMWH was used, there were no reports of thromboembolic complications. Major bleeding complications were rare and reported by 2% of the respondents.
Conclusions: This was the first documentation that clinical practice of bridging perioperative anticoagulation in children with mechanical heart valves varies widely among pediatric cardiac specialists. There is poor adoption of published guidelines and a tendency toward more conservative strategies. Further studies comparing the safety and efficacy of LMWH vs. UFH as perioperative anticoagulation agents in children with mechanical heart valves are needed to further clarify our findings. Quality assurance initiatives and education are also needed to improve guidelines adherence and standardize practice management.
