Prominent Chiari Network as a Cause of Cyanosis in Infants: A Case Report and Implications for Pediatric Cardiology Practice

Journal of Clinical Ultrasound, EarlyView.
A prominent Chiari network can cause cyanosis in infants by inducing a positional right‐to‐left atrial shunt. Accurate diagnosis enabled conservative management, delaying surgery until optimal conditions. This case emphasizes the importance of echocardiographic evaluation in differentiating cyanosis mechanisms to guide appropriate treatment in ...

Timolipoma simulando cardiomegalia

Revista do Colégio Brasileiro de Cirurgiões
Thymolipoma is a rare benign tumor of the thymus. Because of its large size and pliability the mass usually drapes itself around the heart, conforming to its borders and producing a large radiographic shadow easily mistaken as cardiomegaly.

Simulation of dB/dt‐Over‐Electric Field Cardiac Magnetostimulation Safety Ratios in 75 Body Models and 18 Gradient Systems

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The IEC 60601‐2‐33 standard provides consensus‐based safety provisions for MRI equipment. Protection of patients against cardiac stimulation (CS) is based on limiting the maximum E‐field induced by MRI gradient coils. In practice, this is achieved by imposing a conservative dB/dt threshold on any gradient waveform.

The caveats in the diagnosis of anomalous origin of left coronary artery from pulmonary artery (ALCAPA) [PDF]

, 2010
Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) is an infrequent, well described, but important anomaly of the coronary origin. Early diagnosis and prompt surgical treatment of the disease can be life saving. However, there are
