First successful percutaneous treatment of a totally occluded HeartWare outflow graft: Case report and literature review.

ABSTRACT: As the number of implanted left ventricular assist devices (LVADs) used increases, the frequency of chronic complications encountered also increases. The pause of blood flow in the outflow graft is a rare, but fatal, complication. The aim of this article was to present the case of a patient in whom HeartWare outflow graft occlusion was removed by balloon angioplasty and to examine the treatment modalities of HeartWare outflow graft occlusions that have been percutaneously performed to date. The literature was searched for percutaneous interventions on outflow grafts of the left ventricular assist devices. The results of six patients who underwent interventions on outflow grafts were analyzed. Three of six patients with HeartWare outflow graft stenosis were treated with covered stents, while the remaining three were treated with bare metal stents. All procedures were applied successfully. Percutaneous interventions can be performed with appropriate equipment in patients with HeartWare outflow graft stenosis or total occlusion.

Project description:PurposeThe PEVAR Trial demonstrated that compared to open femoral exposure, elective percutaneous endovascular AAA repair (ePEVAR) is associated with decreased perioperative morbidity and access site complications. We hypothesized that PEVAR for ruptured AAA (rPEVAR) may also improve perioperative morbidity compared to open femoral exposure (rEVAR). There are currently no reports that evaluate the utility and outcomes of rPEVAR.Materials and methodsFrom 2015 to 2021, all patients who underwent an endovascular repair of a ruptured AAA at a single institution were included in the study and grouped into rPEVAR and rEVAR. Demographics, procedural details (successful preclose technique, conversion to femoral cutdown), postoperative variables (blood transfusion, ICU and hospital length of stay) and short-term outcomes (30-day major adverse events (30-day MAE) and 30-day femoral access-site complications (30-day FAAC)) were collected and compared with 50 historical ePEVAR patients from the PEVAR Trial. Statistical significance was determined using χ 2 or Fisher's exact test for categorical variables, and Mann-Whitney U-test for continuous variables.Results35 patients were identified (21 rPEVAR; 14 rEVAR), 86% were male with a mean age of 72 ± 9 years. All patients underwent emergent endovascular aortic repair with 100% technical success. Seventeen patients (49%) presented with evidence of hemorrhagic shock and 22 patients (63%) had blood transfusion. 30-day MAE occurred in 12 patients (34%) (7 rPEVAR; 5 rEVAR). There was no difference in demographic, perioperative outcomes and 30-day MAE rate between rPEVAR and rEVAR patients. Compared to ePEVAR patient (from PEVAR trial), rPEVAR patients had higher rate of 30-day MAE (34% vs. 6%; p < 0.006) but no difference in 30-day FAAC (19% vs. 12%; p = 0.54). The success rate of the preclose technique was higher in ePEVAR compared to rPEVAR (96% vs. 76%; p = 0.02), but the rate of conversion to femoral cutdown was similar between the two groups (10% vs. 4%; p = 0.57).ConclusionEmergent rPEVAR appears to have similar outcomes when compared to rEVAR. Although patients undergoing rPEVAR have higher 30-day major adverse events rate compared to ePEVAR, the method of percutaneous femoral cannulation does not appear to increase the overall procedural or 30-day femoral artery access-site complications.
