Paravalvular Leak Closure Case Presentation Samir Kapadia, MD Professor of Medicine Director, Cardiac Catheterization Laboratories Cleveland Clinic DISCLOSURE : NONE
Samir Kapadia, MD I have no real or apparent conflicts of interest to report. My presentation will include off label discussions: Valves
Clinical Presentation • 79 year old lady – s/p St. Jude #19 AV in 1990 – s/p St. Jude # 23 MV in 2004 with CABG (L-AD and SVG to OM) – AF, DDD pacemaker – Severe hemolytic anemia worsening over last 1 year. 30 blood transfusions last year. 8 in last 2 months. – Class III CHF (gets SOB moving from chair to chair) – Question of aortic valve leaflet dysfunction
Echocardiogram • TTE – EF – normal (55%) – AV – gradient p/m = 9/5 mm Hg – MV – gradient p/m = 20/8 mm Hg – RVSP = 62 mm Hg • TEE (difficult to pass a probe, esophageal stricture, needed direct visualization with scope to pass the probe) – 3+ MR paravalvular
TEE
Labs • Blood cultures (-) • LDH = 3618 U/L • AST = 166 U/L • T Bili 1. 9 mg/d. L • Haptoglobin <20 mg/d. L • BNP = 443 pg/m. L
Procedure • Conscious sedation • Image fusion and planning of the procedure – stiff wire in LV – will not exteriorize – if needed TA puncture
Approaches to PVL Closure Kapadia and Tuzcu, Circ Cardiovasc Interv 2011; 4; 308 -310
Procedure • Conscious sedation • Image fusion and planning of the procedure – stiff wire in LV – will not exteriorize – if needed TA puncture • Assessment of valves and coronaries • Initial procedure with fluoro and ICE • Pediatric probe
Where is the Leak? Foster GP et al, Ann Thorac Surg 1998; 65: 1025– 1031

F/u Labs Day Prior Post Day 1 • LDH = 3618 U/L • LDH = 2303 U/L • AST = 166 U/L • AST = 80 U/L • T Bili 1. 9 mg/d. L • T Bili 1. 3 mg/d. L • Haptoglobin <20 mg/d. L • BNP = 443 pg/m. L one month Hg = 10. 4
