Objectives Paravalvular leaks (PVL) occur in up to 17% of all surgically implanted prosthetic valves. Re-operation is associated with high morbidity and mortality.Transcatheter closure via a surgical transapical approach(TAp) is an emerging alternative for selected high-risk patients with PVL. The aim of this study was to compare the in-hospital outcomes of patients who underwent surgery and TA-closure for PVL in our single-centre experience. Methods From October 2000 to June 2013, 139 patients with PVL were treated in our Institution. All the TA procedures were performed under general anaesthesia in a hybrid operative room: in all but one case an Amplatzer Vascular Plug III device was utilized. Results Hundred and thirty-nine patients with PVLwere treated: 122 patients (87.3%) underwent surgical treatment (68% mitral PVL; 32% aortic PVL) and 17 patients (12.2%) underwent a transcatheter closure via a surgical TAp approach (all the patients had mitral PVL; one case had combined mitral and aortic PVLs); in 35% of surgical patients and in 47% of TAp patients, multiple PVLs were present. The mean age was 62.5±11 years; the Logistic EuroScore was 15.4±3. Most of the patients were in New York Heart Association (NYHA) functional class III-IV (57%). Symptomatic haemolysis was present in 35% of the patients, and it was particularly frequent in the TAp (70%). Many patients had <1 previous cardiac operation (46% overall and 82% of TAp patients were at their second of re-operation). Acute procedural success was 98%. In-hospital mortality was 9.3%; no in-hospital deaths occurred in patients treated through a TAp approach. All the patients had less than moderate residual valve regurgitation after the procedure. Surgical treatment wasidentified as a risk factor for in-hospital death at univariate analysis (OR: 8,95%CI: 1.8-13; P = 0.05).Overall actuarial survival at follow-up was 39.8±7% at 12 years and it was reduced in patients who had <1 cardiac re-operation (42±8 vs. 63±6% at 9 years; P = 0.009). Conclusions Atranscatheter closure via a surgical TAp approach appears to be a safe and effective therapeutic option in selected highrisk patients with PVL and is associated with a lower hospital mortality than surgical treatment, in spite of higher predicted risk. Long-term survival remains suboptimal in these challenging patients.
