This study investigated the incidences of various conduction abnormalities after rapid-deployment aortic valve replacement using Edwards Intuity (Edwards Lifesciences, Irvine, CA) valve and the temporal changes of these abnormalities during the postoperative course. We modified the procedure by placing additional anchoring sutures and using a 5-mm videoscope to achieve "complete annulus fitting." Direct visual inspection by videoscopy inside and outside the valve guaranteed complete annulus fitting. Overall 167 patients who underwent rapid-deployment aortic valve replacement during the study period were included in the analysis of postoperative conduction abnormalities. After rapid-deployment aortic valve replacement, third-degree atrioventricular block occurred in 18 patients (10.8%), but 15 patients recovered to sinus rhythm at median postoperative 10 days. Left or right bundle branch block occurred in 67 patients (40.1%), but 44 patients returned to their original rhythm at median postoperative 12 days. Delayed-onset conduction abnormalities occurred in 35 patients (21.0%) at median postoperative day 4, and spontaneously regressed in 28 patients. The incidence of conduction abnormalities after rapid-deployment aortic valve replacement was high, but most of these abnormalities spontaneously recovered. These good results may be attributed to our implantation technique.

UI MeSH Term Description Entries
D011183 Postoperative Complications Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery. Complication, Postoperative,Complications, Postoperative,Postoperative Complication
D012075 Remission, Spontaneous A spontaneous diminution or abatement of a disease over time, without formal treatment. Spontaneous Healing,Spontaneous Regression,Spontaneous Remission,Healing, Spontaneous,Regression, Spontaneous,Spontaneous Healings,Spontaneous Regressions
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000075224 Cardiac Conduction System Disease Diseases characterized by pathological irregularities in the HEART CONDUCTION SYSTEM. They may be associated with other heart diseases and syndromes (e.g., BRUGADA SYNDROME; NEUROMUSCULAR DISEASE, HEART BLOCKS), isolated or may result from injuries. You can have a conduction disorder without having an arrhythmia, but some arrhythmias arise from conduction disorders. OMIM: 601144. Cardiac Conduction Defect,Cardiac Conduction Defects,Cardiac Conduction System Diseases,Conduction Defect, Cardiac,Defect, Cardiac Conduction
D000082862 Aortic Valve Disease Diseases involving the AORTIC VALVE functionality. Aortic valve disease often results in a backward and/or regurgitated blood flow into the LEFT VENTRICLE or a decreased blood flow from the heart. It includes congenital (e.g., bicuspid aortic valve), syndromic, and acquired (e.g., age-related, infection-associated) conditions.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons. Retrospective Study,Studies, Retrospective,Study, Retrospective
D013997 Time Factors Elements of limited time intervals, contributing to particular results or situations. Time Series,Factor, Time,Time Factor
D015994 Incidence The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from PREVALENCE, which refers to all cases in the population at a given time. Attack Rate,Cumulative Incidence,Incidence Proportion,Incidence Rate,Person-time Rate,Secondary Attack Rate,Attack Rate, Secondary,Attack Rates,Cumulative Incidences,Incidence Proportions,Incidence Rates,Incidence, Cumulative,Incidences,Person time Rate,Person-time Rates,Proportion, Incidence,Rate, Attack,Rate, Incidence,Rate, Person-time,Rate, Secondary Attack,Secondary Attack Rates
