Pediatric Tuberous Sclerosis Protocol

Pediatric Tuberous Sclerosis Patients Undergoing ELECTIVE General Anesthesia

LESS THAN (<) 3 Years Old

1. At least one ECG

a. If history of abnormal ECG – ECG within 12 months.

2. Pediatric Cardiology evaluation within 12 months

3. At least one post-natal ECHO

a. NO Cardiac Rhabdomyoma OR Regressing Rhabodmyoma (including prenatal echo) = ECHO OR Pediatric Cardiology evaluation within 12 months that includes recommendations for continued surveillance (Ex: ECHO at two years old, etc).

b. Non-regressing Cardiac Rhabdomyoma (including prenatal echo) = ECHO within 12 months

3-12 Years Old

1. At least one ECG within 3 years

a. If history of abnormal ECG – ECG AND Pediatric Cardiology evaluation within 12 months

2. At least one post-natal ECHO

a. NO Cardiac Rhabdomyoma OR Regressing Rhabodmyoma (including prenatal echo) = normal ECHO at/after age of two OR Pediatric Cardiology evaluation that includes recommendations for continued surveillance (Ex: no need for f/u ECHO, etc.)

b. Non-regressing Cardiac Rhabdomyoma (including prenatal echo) =

i. If most recent ECHO shows a non-obstructive rhabdomyoma, patient requires an ECHO OR a Pediatric Cardiology evaluation within 12 months that includes recommendations for continued surveillance (Ex: echo q2 years).

ii. If most recent ECHO shows an obstructive rhabdomyoma, patient requires an ECHO AND a Pediatric Cardiology evaluation within 12 months

12-15 Years Old

1. At least one ECG within 3 years

a. If history of abnormal ECG – ECG AND Pediatric Cardiology evaluation within 12 months

2. Pediatric Cardiology Evaluation within 3 years (to assess for re-emergence of pathology with puberty)

3. At least one post-natal ECHO - Repeat Echo per Cardiology Recommendation (see echo requirements for 3-12 years old for more specific information)

15-18 Years Old

1. At least one ECG within 3 years

a. If history of abnormal ECG – ECG AND Pediatric Cardiology evaluation within 12 months

2. Prior Pediatric Cardiology Evaluation during Adolescence

3. At least one post-natal ECHO - Repeat Echo per Cardiology Recommendations (see echo requirements for 3-12 years old for more specific information)

4. Renal Function Panel with GFR within 12 months

Tuberous Sclerosis is a genetic syndrome affecting many different organ systems. Patients manifest widespread harmatomas including cardiac rhabdomyomas. AHA has issued a special report regarding these patients and states that “There is an increasing appreciation for latent cardiovascular phenotypes, indicating a need for continued surveillance of these patients.1” The AHA also states “80% to 85% of children with confirmed TSC have identifiable rhabdomyomas when younger than 2 years.1” To better serve these patients and to avoid unnecessary studies, the OU Children’s Hospital Pediatric Anesthesiology, Cardiology, and Hematololgy/Oncology divisions have collaborated to devise the above guidelines. We are placing a heavier emphasis on continued pediatric cardiology assessment and less emphasis on yearly echocardiograms (especially in those patients > 3 years old).
