Cardiovascular CT for preprocedural planning of transcathete | Figure 1

Cardiovascular CT for preprocedural planning of transcatheter aortic valve replacement (TAVR).

(A) Double-oblique approach to identifying aortic annular plane before TAVR (black arrows). Aortic annuli should be measured at the leaflet insertions rather than in the valve plane.

(B) Volume-rendered imaging of the aorta, aortic annulus, and aortic valve. Blue line indicates the plane of the aortic annulus. When all points in the aortic annular plane are aligned (as indicated by blue line), these CT projection angles can be helpful to proceduralists as a guide to which angles may be useful at the time of the TAVR procedure.

Diameter (C), area (D), and perimeter (E) measurements of the aortic annulus for proper sizing of the TAVR prostheses.

Measurement of the right coronary ostial height (F), and left coronary ostial height (G), to ensure that the TAVR will not occlude the coronary ostia.

A 52-year-old man presented with a 20-minute history of chest pain radiating to the left shoulder and neck, associated with dyspnea and diaphoresis. He had a history of hypertension, long-term smoking, and a sedentary lifestyle. On physical examination, bibasilar crackles were noted on lung auscultation. An electrocardiogram (ECG) was performed in the primary care setting, and the patient was promptly referred to the emergency department.

A 28-year-old woman presented with a 3-day history of intense pruritus over the lower back. She reported no recent travel or exposure to new environments. She cares for a small kennel with approximately eight dogs rescued from the streets. Physical examination revealed multiple small vesicles, some clustered and others scattered, predominantly involving the lumbar region and the left gluteal area.

A 4-month-old male infant presented with skin lesions localized to the chin for the past 3 days. Physical examination revealed multiple small pustules with surrounding inflammatory signs on the chin, along with a few scattered papules on the chest.

patient in late teens presenting after a collapse, no chest pain, no previous cardiac history, no history of sudden death in family, are there any features in this ekg that would warrant further work-up or is this just a pediatric ekg?
