Abstract

Background Subaortic pannus formation complicates bioprosthetic aortic valve (AV) replacement. We report an extreme case in a continuous-flow left ventricular assist device (LVAD) patient. Case summary A 49-year-old Caucasian female with dilated cardiomyopathy was bridged to transplant with a HeartWare Ventricular Assist Device (Medtronic). Duration of support was prolonged, 6 years & 7 months, due to allosensitization requiring desensitization. Pump thrombosis occurred 2 years & 4 months post-LVAD requiring alteplase thrombolysis. The patient underwent bioprosthetic AV replacement 3 years & 10 months post-LVAD for symptomatic aortic incompetence. Transthoracic echocardiography (TTE) performed 1 year and 2 years post-bioprosthetic AV replacement repeatedly demonstrated an AV closed during all cardiac cycles without incompetence and nil flow through the left ventricular outflow tract (LVOT). Following transplant, analysis of explanted heart revealed a fused AV. A pannus adherent to the underside of the AV had formed across the entire AV outlet, with complete obliteration of LVOT. This subaortic pannus was not visualized on previous TTE. Histologically, the pannus consisted of hypocellular fibrous tissue with chronic inflammatory cells, spindle histiocytes, and myofibroblasts scattered throughout the loose fibromyxoid stroma, the latter highlighted on CD68 immunohistochemical stain (IHC). Partial endothelialization on the pannus surface was highlighted on ERG and CD31 IHC. Neither calcification nor signs of acute inflammation were noted. In contrast to previous cases, there was no evidence of associated thrombus macroscopically or microscopically. Discussion Prolonged LVAD support may facilitate subaortic pannus following bioprosthetic AV replacement due to AV closure and altered transvalvular flow. Due to the parallel LVAD circulation, subaortic pannus may develop asymptomatically, without haemodynamic compromise, allowing progression to total LVOT obstruction. This requires consideration prior to LVAD explantation in bridge-to-recovery patients. [ABSTRACT FROM AUTHOR]

Abstract

Background: Dynamic respiratory maneuvers induce heterogenous changes to flow‐pulsatility in continuous‐flow left ventricular assist device patients. We evaluated the association of these pulsatility responses with patient hemodynamics and outcomes. Methods: Responses obtained from HVAD (Medtronic) outpatients during successive weekly clinics were categorized into three ordinal groups according to the percentage reduction in flow‐waveform pulsatility (peak‐trough flow) upon inspiratory‐breath‐hold, (%∆P): (1) minimal change (%∆P ≤ 50), (2) reduced pulsatility (%∆P > 50 but <100), (3) flatline (%∆P = 100). Same‐day echocardiography and right‐heart‐catheterization were performed. Readmissions were compared between patients with ≥1 flatline response (F‐group) and those without (NF‐group). Results: Overall, 712 responses were obtained from 55 patients (82% male, age 56.4 ± 11.5). When compared to minimal change, reduced pulsatility and flatline responses were associated with lower central venous pressure (14.2 vs. 11.4 vs. 9.0 mm Hg, p = 0.08) and pulmonary capillary wedge pressure (19.8 vs. 14.3 vs. 13.0 mm Hg, p = 0.03), lower rates of ≥moderate mitral regurgitation (48% vs. 13% vs. 10%, p = 0.01), lower rates of ≥moderate right ventricular impairment (62% vs. 25% vs. 27%, p = 0.03), and increased rates of aortic valve opening (32% vs. 50% vs. 75%, p = 0.03). The F‐group (n = 28) experienced numerically lower all‐cause readmissions (1.51 vs. 2.79 events‐per‐patient‐year [EPPY], hazard‐ratio [HR] = 0.67, p = 0.12), reduced heart failure readmissions (0.07 vs. 0.57 EPPY, HR = 0.15, p = 0.008), and superior readmission‐free survival (HR = 0.47, log‐rank p = 0.04). Syncopal readmissions occurred exclusively in the F‐group (0.20 vs. 0 EPPY, p = 0.01). Conclusion: Responses to inspiratory‐breath‐hold predicted hemodynamics and readmission risk. The impact of inspiratory‐breath‐hold on pulsatility can non‐invasively guide hemodynamic management decisions, patient optimization, and readmission risk stratification. [ABSTRACT FROM AUTHOR]
