Late Function After Surgery for Transposition of the Great Arteries

The investigators proposed to review the exercise tolerance, cardiac function, and quality of life in patients born with transposition of the great arteries that have undergone surgery with either the Mustard or Senning procedure. Participants will complete a questionnaire. The investigators will review the participants' recent cardiac function testing which will assess their current health status. These tests include an echocardiogram, a metabolic exercise stress test, cardiac imaging, and a 24-hour Holter monitor. This collection of testing results will be compared specifically with previously acquired data during the first phases of this study (published in 2001 and 2007).

Study Overview

• Status: Completed
• Conditions: Transposition of Great Vessels

Detailed Description

1. Enrolled subjects must consent to the study and authorize release of health information. All studies obtained as part of this research study are considered part of routine care.
2. Prior to testing, subjects must complete a questionnaire assessing quality of life. This is the same questionnaire that has been used in the previous portions of this study.
3. The investigators will review results of cardiac imaging for all participants consisting of a cardiac MRI or cardiac CT obtained within the last 5 years. If this data does not exist or is outdated, participants will have a new study.
4. The investigators will review results of cardiac imaging for all participants consisting of an echocardiogram within the last 5 years. If this data does not exist or is outdated, participants will have a new study.

5. The investigators will review results of cardiac function testing for all participants consisting of an exercise stress test obtained within the last 5 years. If this data does not exist or is outdated, participants will have a new study. End criteria for the exercise stress test includes either

   a. Achieving two or more of the following: i. Heart rate of > 95% of age-predicted maximum (using equation 220-age = maximal heart rate) ii. RER > 1.1 iii. VO2 plateau defined as The VO2 plateau was defined as a change in VO2 during the final minute of exercise less than 2 SD below the mean of increases between previous workloads iv. RPE > 8 on OMNI RPE scale v. Volitional exertion OR b. Achievement of any of the contraindications to exercise testing.

6. The investigators will review results of cardiac rhythm monitoring for all participants consisting of a 24 hour Holter monitor obtained within the last 5 years. If this data does not exist or is outdated, participants will have a new study.

Study Population

Participants must have had an atrial switch procedure (Mustard or Senning operation) and have participated in the prior two installments of this study.

Description

Inclusion Criteria:

2. Patients must be willing to adhere to the guidelines of this study

Exclusion Criteria:

1. Patients who are medically unstable
2. Patients that are non-ambulatory
3. Patients with a history of exercise induced arrhythmia
4. Patients with atrial flutter or history of treatment resistant atrial flutter
5. Patients who are pregnant.
