New Tool to Guide Transcatheter Aortic Valve Replacement

Key points: 

  • Although all patients underwent valve placement in the proper anatomical location, moderate paravalvular leakage (PVL) occurred in four patients, and a second valve was required in two patients, resulting in a device success of 96.3%.

  • New PPMI within 30 days was required in 11 patients (6.7%), all because of complete atrioventricular block; patients with baseline right bundle branch block (RBBB) had a higher incidence of new PPMI than did those without RBBB (23.8% vs 4.2%; P < .001).

  • Patients whose device was implanted inside the MS had a significantly lower incidence of new PPMI (overall 2.1% vs 13.4%; P = .005); this finding was consistent in patients with baseline RBBB (6.7% vs 66.7%; P = .004) or without RBBB (1.2% vs 8.2%; P = .041).

  • By 30 days, there was one death, which occurred as a result of bleeding in a patient with liver cirrhosis after a successful TAVR procedure; four patients experienced disabling strokes, and vascular complications developed in 16 patients.
