myocardial metabolic abnormality in a primary left atrial rhabdomyosarcoma: localized 1h mr spectroscopy
نویسندگان
چکیده
we report a 73-year-old woman with primary left atrial rhabdomyosarcoma and its 1h mr spectroscopy (mrs) findings. the tumor showed a 2.8 cm sized lesion in the posteroinferior atrial wall on mri. 1h mr spectra were acquired using a point-resolved spectroscopy (press) sequence with electrocardiographic (ecg) gating and respiratory motion. the use of 1h-mrs allowed the quantification of triglyceride (tg) peak groups at 0.9 and 1.3 ppm, and unsaturated group of lipids at 2.1 ppm, creatine (cr) at 3.0 ppm, and choline (cho) at 3.2 ppm. the percentages of the myocardial metabolites based on water-peak in the interventricular septum were tg 18.4%, cr 1.6%, cho 3.3% and unsaturated group 4.0%, whereas the rhabdomyosarcoma showed tg 118.8%, unsaturated group 5.1%, cr 1.3%, cho 3.5% and the olefinic components of fatty acid at 5.4 ppm 24.5%. this case demonstrates that 1h-mrs is potentially useful to diagnose the rhabdomyosarcoma by quantifying the myocardial metabolites which are important biomarkers for heart function and diseases.

We report a 73-year-old woman with primary left atrial rhabdomyosarcoma and its 1H MR spectroscopy (MRS) findings. The tumor showed a 2.8 cm sized lesion in the posteroinferior atrial wall on MRI. 1H MR spectra were acquired using a point-resolved spectroscopy (PRESS) sequence with electrocardiographic (ECG) gating and respiratory motion.

A 27-year-old man complained of frequent chest pain and recurrent syncope for 3 months. He was in mild respiratory distress with a respiratory rate of 20/min and a heart rate of 94 bpm, regular in rhythm. His blood pressure was 120/70 mm Hg. Cardiac auscultation revealed a distinct early diastolic click followed by a grade 2/5 diastolic decrescendo murmur at the apex that was variable in charac...

Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
