We describe a unique presentation of a pheochromocytoma in a normotensive teenager, who presented with symptoms of headache, neck pain, and palpitations. Holter and event monitor tracings revealed intermittent junctional rhythm causing electromechanical dyssynchrony between atrial and ventricular contraction resulting in reported symptoms. Exercise stress testing helped correlate symptomatic junctional rhythm events to episodic hypertension which led to the eventual diagnosis of pheochromocytoma.

- The study aimed to evaluate health-related quality of life (HRQOL) in children and young adults with Marfan syndrome participating in a trial, using the Pediatric Quality of Life Inventory (PedsQL).
- Results showed that younger patients (5-18 years) had significantly lower HRQOL scores in both physical and psychosocial areas compared to healthy peers, while older patients (19-25 years) scored higher, indicating a shift in HRQOL with age.
- Factors like age, sex, and neurodevelopmental disorders were found to significantly impact HRQOL, whereas treatment type (atenolol vs. losartan) and physical severity of Marfan syndrome did not exhibit significant differences.
Background: Pulmonary artery acceleration time (PAAT) is a noninvasive method to assess pulmonary hemodynamics, but it lacks validity in children. The aim of this study was to evaluate the accuracy of Doppler echocardiography-derived PAAT in predicting right heart catheterization (RHC)-derived pulmonary artery pressure (PAP), pulmonary vascular resistance (PVR), and compliance in children.
Methods: Prospectively acquired and retrospectively measured Doppler echocardiography-derived PAAT and RHC-derived systolic PAP, mean PAP (mPAP), indexed PVR (PVRi), and compliance were compared using regression analysis in a derivation cohort of 75 children (median age, 5.
Background: Doppler echocardiography (DE) is widely used as a surrogate for right heart catheterization (RHC), the gold standard, to assess and monitor elevated right heart pressure in children. However, its accuracy has not been prospectively validated in children. The objectives of this study were to evaluate the accuracy of DE in predicting simultaneously measured right ventricular (RV) pressure by RHC in pediatric patients and to determine if the degree of RV hypertension affects the accuracy of DE in assessing right heart pressure.
