OBJECTIVE: To evaluate the clinical outcomes of TAVR patients followed for at least one year after trans-apical approach with prosthetic attachment sutures secured by automated titanium fasteners.
METHODS: We conducted a single-institution retrospective review of clinical outcomes for patients involved in an on-going IRB study regarding Trans-Apical TAVR approach. During the 34-month period from January 2014 to October 2016, a total of 164 Trans-Apical TAVRs were performed at our institution using automated titanium fastener technology. Echocardiographic guidance to best point of entry, two 2-O Prolene vertical mattress sutures placed under rapid ventricular pacing. The 24 Fr. sheath is removed, after TAVR placement, with rapid ventricular pacing and automated titanium fasteners. Inhospital and 1 year clinical outcomes were evaluated. Patient post-operative histories, TVT registry, physician records and follow-up studies, such as echocardiography, were analyzed.
RESULTS: Patient records from a total of 164 consecutive Trans-Apical TAVRs were reviewed. All Trans-Apical TAVRs sites were successfully closed with automated titanium fasteners. Mean age for all patients was 84. The median STS predicted risk of mortality was 7.6%. Other concomitant comorbidities included previous sternotomy 40.2%, PAD 51.2%, Diabetes 28%, Dialysis 1.2%, and home O2 6.7%. The 30-day mortality rate was 3.7%, 1-year mortality was 5.5%. 30 -day stroke rate was 1.2%. The valve in previous surgical valve procedure rate was 9.8%. Other complications included permanent pacemaker 11%, conversion to sternotomy 0.6%, vascular complications 0%, wound infection 0.6% and atrial fibrillation 7%. No adverse outcomes were attributable to the use of automated titanium fasteners. Discharge echocardiograms results: aortic insufficiency; None 36.6%, Trace 42.7%, Mild 18.3%, Moderate 2.4% and Severe 0%. The mean gradient pre TAVR was 47.3mmHg vs 8.0 mmHg post TAVR.
CONCLUSIONS: At a minimum of one-year follow-up, automated titanium fasteners appear to be safe and effective for securing ventriculotomy site after trans-apical TAVR. The use of titanium fasteners along with rapid ventricular pacing seems to be reliable technique for apical closure.
