Cardiac CTA parameters predict put up-transcatheter aortic valve replacement mortality

severe aortic stenosis undergoing TAVR,” concluded corresponding creator U. Joseph Schoepf from the Clinical University of South Carolina’s Coronary heart and Vascular Center.

Schoepf and colleagues’ retrospective single-center leer incorporated 175 sufferers with severe aortic stenosis (92 male, 83 feminine; median age, 79 years) who underwent cardiac CTA for scientific pre-TAVR overview. Maximum and minimal left atrium volumes agree with been calculated utilizing biplane place-size measurements, and the values agree with been listed to body ground place: LAVI_max and LAVI_min, respectively.

In their sample, a reduced LAEF independently predicted all-place off mortality inner 24 months put up-route of (hazard ratio 0.97 [0.94–0.99]; p=.02). Furthermore, when incorporating LAEF, the c-index of the Society of Thoracic Surgeons Predicted Threat of Mortality greatly increased from 0.64 to 0.70.

Acknowledging that atrial parameters are more frequently assessed utilizing transthoracic echocardiography, every atrial volume and atrial aim will also be reliably assessed utilizing cardiac CTA, “which now represents the gold typical for preprocedural planning in sufferers undergoing TAVR,” the authors of this AJR article added.
