It is unknown if long-term PED5I therapy beyond the early post-operative period provides any clinical benefit in stable outpatients, who have recovered from post-operative RV failure under univentricular device support. This study aimed to investigate the impact of PDE5I discontinuation on RV function and cardiopulmonary exercise capacity in patients on durable LVAD support.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>We enrolled 31 clinically stable LVAD recipients on long-term oral PDE5I therapy. The mean age was 53 years, and 90% were male. Patients discontinued PDE5I and underwent cardiopulmonary exercise testing, echocardiography, LVAD interrogation, and biomarker analysis at baseline and 4 weeks after PDE5I withdrawal. At 4 weeks, no significant changes were observed in echocardiographic indices of RV morphology and function but an increase in peak tricuspid regurgitation velocity (2.1 vs. 2.4 m\/s, P = 0.01). Peak oxygen consumption (11.4 vs. 11.8 mL\/min\/kg, P = 0.52), minute ventilation\/carbon dioxide production slope (33 vs. 35, P = 0.56), N-terminal pro-brain natriuretic peptide (1455 vs. 1399 pg\/mL, P = 0.55), flow and power readings of the device, and quality of life (Kansas City Cardiomyopathy Questionnaire score 78.3% vs. 77.5%, P = 0.62) exhibited no significant changes. We observed an increase in 6-min walking distance (346 vs. 364 m, P = 0.03). Two patients were hospitalized for non-cardiac reasons (subtherapeutic INR, driveline infection). No patient was hospitalized for cardiac decompensation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In LVAD patients with a history of early post-operative RV failure, discontinuation of long-term PDE5I therapy was not associated with deterioration of RV function, exercise capacity, and quality of life.
