New-Onset Atrial Fibrillation After Aortic Valve Replacement Comparison of Transfemoral, Transapical, Transaortic, and Surgical Approaches
ObjectivesThis study sought to determine the incidence of new-onset atrial fibrillation (AF) associated with different methods of isolated aortic valve replacement (AVR)—transfemoral (TF), transapical (TA), and transaortic (TAo) catheter-based valve replacement and conventional surgical approaches.BackgroundThe relative incidences of AF associated with the various access routes for AVR have not been well characterized.MethodsIn this single-center, retrospective cohort study, we evaluated a total of 231 consecutive patients who underwent AVR for degenerative aortic stenosis (AS) between March 2010 and September 2012. Patients with a history of paroxysmal, persistent, or chronic AF, with bicuspid aortic valves, and patients who died within 48 h after AVR were excluded. A total of 123 patients (53% of total group) qualified for inclusion. Data on documented episodes of new-onset AF, along with all clinical, echocardiographic, procedural, and 30-day follow-up data, were collated.ResultsAF occurred in 52 patients (42.3%). AF incidence varied according to the procedural method. AF occurred in 60% of patients who underwent surgical AVR (SAVR), in 53% after TA-TAVR, in 33% after TAo-TAVR cases, and 14% after TF-TAVR. The episodes occurred at a median time interval of 53 (25th to 75th percentile, 41 to 87) h after completion of the procedure. Procedures without pericardiotomy had an 82% risk reduction of AF compared with those with pericardiotomy (adjusted odds ratio: 0.18; 95% confidence interval: 0.05 to 0.59).ConclusionsAF was a common complication of AVR with a cumulative incidence of >40% in elderly patients with degenerative AS who underwent either SAVR or TAVR. AF was most common with SAVR and least common with TF-TAVR. Procedures without pericardiotomy were associated with a lower incidence of AF

Multimodality image guidance with Dyna-CT for transcatheter treatment of paravalvular leak of a stentless valve
The transcatheter treatment of paravalvular leaks (PVL) are technically challenging procedures; they pose increasing difficulty in cases where there is a stentless valve, without the usual fluoroscopic landmarks. Hence, there is limited experience in treating this defect percutaneously. We present a case of a patient with an aortic PVL of a stentless valve and how the integrated use of multi-imaging modalities (transesophageal echocardiography, computed tomography and rotational angiography) allowed the demarcation of landmarks onto live fluoroscopy and guided the transcatheter occlusion of the PVL
