(FIT)-Module 3 Workshop 5: Invasive and Non-Invasive Correlation-Stevenson Workshop 5

Stevenson Workshop 5

Pdf Summary

In Workshop #5 on invasive and noninvasive correlations, several cases were presented to assess the mechanisms and origins of different types of tachycardia. In case 1, a 72-year-old male with a history of old inferior wall myocardial infarction presented with palpitations and dyspnea. The most likely tachycardia mechanism was determined to be bundle branch reentry. Case 2 involved a wide QRS tachycardia, and the most likely diagnosis was bundle branch reentry. Case 3 focused on the activation maps of three different ventricular tachycardias, and the correct answer was that VT C was most likely due to automaticity. Case 4 involved a 58-year-old male with nonischemic dilated cardiomyopathy, and the arrhythmia was likely originating from the inferior left ventricular endocardium. In Case 5, a 72-year-old male with coronary artery disease was likely experiencing VT from the basal inferior left ventricular septum. Case 6 involved a 35-year-old female with exercise-induced syncope, and the most likely diagnosis was cardiac sarcoidosis based on ECG characteristics during isoproterenol infusion. Case 7 focused on a 48-year-old male with recurrent wide complex tachycardias, and the most likely diagnosis was cardiac sarcoidosis. Case 8 involved a patient with repaired tetralogy of Fallot, and the most likely cause of VT was a conducting isthmus between the pulmonary valve annulus and VSD patch. Lastly, in Case 9, the most likely source of the arrhythmia was the RV moderator band focus.
