Effect of New-Onset Left Bundle Branch Block After Transcatheter Aortic Valve Implantation (CoreValve) on Mortality, Frequency of Re-Hospitalization, and Need for Pacemaker

Impact of Bundle Branch Block on Permanent Pacemaker Implantation after Transcatheter Aortic Valve Implantation: A Meta-Analysis

“…In the present study, the cumulative proportion of LBBB was 11.9%, including pre-operative LBBB and new-onset LBBB after TAVI. This rate is thus in accordance with previously published data [ 4 , 58 ]. The impact of LBBB on post-TAVI PPI remains controversial [ 49 , 50 , 59 ].…”

“…Atrio-ventricular conduction disturbances and subsequent permanent pacemaker implantation (PPI) represent frequent complication after transcatheter aortic valve implantation (TAVI) [ 1 , 2 ]. Notably, infra-Hisian conductions’ desynchrony such as left bundle branch block (LBBB) and right bundle branch block (RBBB) remain an ongoing issue in TAVI [ 3 , 4 ], especially considering TAVI as well-established therapeutic approach for patients with aortic stenosis at high surgical risk [ 5 ], while considerable advances in procedural techniques tend to extend TAVI indications to patients with a lower surgical risk [ 6 ]. Mechanical stress on the aortic valve annulus, deterioration of the ventricular septum, and local edema may all injury the atrio-ventricular conduction during the TAVI procedures [ 1 , 3 ].…”

Clinical Impact of New-Onset Left Bundle-Branch Block After Transcatheter Aortic Valve Implantation in the Japanese Population ― A Single High-Volume Center Experience ―

“…Previous studies demonstrated a significant decrease in LVEF in patients with N-LBBB after TAVI, 25-27 whereas others did not find this deterioration. 7,8,11 In the present study, LVEF in the PN-LBBB group did not significantly improve throughout the follow-up period, in contrast with that of the No/TN-LBBB group. In addition, mild dilatation of the LVDd was observed after TAVI in the PN-LBBB group.…”

“…4,5 Left bundle-branch block (LBBB) is the most frequent CD after TAVI, with an estimated frequency of 10-36% depending on the study. [6][7][8][9][10][11][12] New-onset LBBB (N-LBBB) is a specific concern of TAVI because the development of LBBB could lead to cardiovascular events including AV block, sudden cardiac death, or heart failure hospitalization; at 1-, 3-, 6-, and 12-month follow up; and annually thereafter. The diagnosis of CD was based on the American Heart Association/American College of Cardiology Foundation/Heart Rhythm Society recommendations.…”

Experiencia de implante percutáneo de la válvula aórtica en pacientes con estenosis aórtica severa descartados de cirugía convencional por alto riesgo quirúrgico en una comunidad rural

“…El motivo del implante fue BAV completo intraprocedimiento en 5 pacientes, y BCRI con BAV de primer grado con HV prolongado en el estudio electrofi siológico en el restante. Este dato coincide con trabajos recientemente publicados [13][14][15] . Si bien la tendencia del uso del marcapasos ha ido disminuyendo, nuestra tasa sobre su empleo coincide con la de otros registros contemporáneos [16][17][18] .…”
