Utilizing Valvuloarterial Impedance to Improve Precision of Aortic Stenosis Quantification
-
Author: Jerry Fan, MD – Baylor Scott & White Medical Center – Temple
-
Time: 10:45-11:30 a.m. CST
-
Abstract/Study Purpose: Degenerative aortic stenosis (AS) is a valvular heart disease resulting in need for valve replacement. The timing of aortic valve replacement is dependent on valve area and flow metrics, which are determined by left ventricular (LV) afterload, myocardial compliance, and workload. Valvuloarterial impedance (Zva) is a useful tool that estimates global LV hemodynamic load which can alter the severity of AS.

Abstract/Study Purpose: Spontaneous coronary artery dissection (SCAD) is myocardial injury occurring as an epicardial coronary artery dissection in the absence of trauma or atherosclerosis. The incidence of cardiogenic shock is 2-3% in SCAD patients, but can increase to 25% in SCAD patients presenting with a STEMI. Treatment is often conservative due to revascularization risks. We present a case of a patient who presented with SCAD complicated by cardiogenic shock requiring a salvage coronary artery bypass graft (CABG) surgery.

Drug Coated Balloon Venoplasty to Treat Iatrogenic Pulmonary Vein Stenosis: A Case Series
-
Author: Mohammed Salih, MD – Baylor Scott & White The Heart Hospital – Plano
-
Time: 1:45-1:55 p.m. CST
-
Abstract/Study Purpose: Pulmonary vein stenosis (PVS) post atrial fibrillation (AF) ablation is now rare. The incidence has dramatically decreased from 42.4% in 1999 to 0.5%-4% in recent years. When PVS is associated with mild symptoms, it may respond to conservative management; however, significant symptoms usually require intervention. Transcatheter intervention with Balloon angioplasty (BA) or stenting is an acceptable intervention strategy but is limited by restenosis (72% for BA versus 33% for stenting at 25 months follow-up). Limited data are available for the use of drug coated balloon (DCB). We present four cases of PVS presented after AF ablation procedure, successfully treated with DCB with no restenosis on follow-up supporting that DCB is an effective strategy.
