Acute myocardial infarction secondary to thrombosis in the right coronary sinus of Valsalva.

547 A 78-year-old woman with a history of paroxysmal atrial fibrillation and hypertension presented with sudden chest pain, dyspnea, and severe hypoxia (O 2 saturation=79%; arterial blood gas test results: Paco 2 level=37.4 mm Hg and Pao 2 level=46.1 mm Hg under high-flow oxygen administration). Electrocardiography showed ST elevation in the inferior leads. Transthoracic echocardiography showed...

Third-degree atrioventricular block in an adult with a giant cardiac fibroma.

A 48-year-old man was admitted with exertional dyspnea. An ECG on admission revealed third-degree atrioventricular block (Figure 1). Transthoracic echocardiography demonstrated a giant mass, 6.4×6.5×7 cm, located in the basal interventricular septum (Figure 2A and 2B and Movie I in the online-only Data Supplement). The left ventricular outlet tract was mildly obstructed (Figure 2C and 2D and Mo...

Multiparametric cardiovascular magnetic resonance assessment of pacemaker-induced alterations in ventricular activation and function.

A 73-year-old woman with presyncope and frequent episodes of symptomatic 2:1 atrioventricular block underwent implantation of a dual-chamber MRI-conditional pacing system (Advisa MRI SureScan pacing system, Medtronic, Minneapolis, MN) to facilitate cardiovascular magnetic resonance (CMR) assessment of apparent isolated right ventricular (RV) hypertrophy seen on transthoracic echocardiography (F...

Can Help Seeking Behavior in Intelligent Tutoring Systems Be Used as Online Measure for Goal Orientation?

Questionnaires to assess goal orientation are widely used. However, recent research indicates some shortcomings. Most significantly, questionnaire data are unable to capture developments and changes in students ́ goal orientation during the learning process. Therefore, it seems appropriate to supplement questionnaire data with online measures that directly tackle students’ behavior. We analyzed ...
