OBJECTIVES The aim of this study was to identify risk factors for new-onset atrioventricular (AV) block requiring pacemaker (PM) implantation after transcatheter aortic valve implantation (TAVI). BACKGROUND High-grade AV block and consecutive PM implantation are frequent complications following TAVI. METHODS For logistic regression analysis, we included(More)
OBJECTIVES Reinterventions after the Ross procedure are a concern for patients and treating physicians. The scope of the present report was to provide an update on the reinterventions observed in the large patient population of the German-Dutch Ross Registry. PATIENTS AND METHODS From 1988 to 2011, 2023 patients (age, 39.05 ± 16.5 years; male patients,(More)
BACKGROUND The purpose of the study is to report major cardiac and cerebrovascular events after the Ross procedure in the large adult and pediatric population of the German-Dutch Ross registry. These data could provide an additional basis for discussions among physicians and a source of information for patients. METHODS AND RESULTS One thousand six(More)
We propose an automatic closed-loop-system for hemodynamic control on the intensive care unit in patients after cardiac surgery. All possible combinations of four standard hemodynamic parameters (mean arterial pressure, on-line cardiac output, central venous pressure and systemic vascular resistance) and four treatment regimens (fluid administration,(More)
OBJECTIVE To evaluate the influence of volume unloading by bidirectional superior cavopulmonary anastomosis on the systemic right ventricle in patients with hypoplastic left heart syndrome. METHODS A total of 90 consecutive patients with hypoplastic left heart syndrome, who had survived the early postoperative period after bidirectional superior(More)
BACKGROUND The study was conducted to assess the need for fenestration for completion of a total cavopulmonary connection (TCPC) with the most recent modification of an extracardiac conduit. METHODS The extracardiac approach was introduced to our institution in January 1999. Between June 2000 and June 2006, 132 consecutive patients were treated without a(More)
BACKGROUND For children who require aortic valve replacement, the Ross operation provides a unique advantage of growth potential of the pulmonary autograft in the aortic position. This study assessed the progression of autograft root diameters and its effect on aortic regurgitation (AR). METHODS Neoaortic echo dimensions from 48 children (<16 years)(More)
BACKGROUND This study sought to assess risk factors for late mortality after the Rastelli operation for patients with transposition of the great arteries, ventricular septal defect, and left ventricular outflow tract obstruction. METHODS Records of 39 patients who underwent the Rastelli operation between 1977 and 2004 were reviewed. Median age at the time(More)
BACKGROUND The quest for an alternative to homografts for reconstruction of the right ventricular outflow tract is ongoing. The Shelhigh No-React (NR-4000PA series) treated porcine pulmonic valve conduit (SPVC) was developed as a potential alternative. METHODS During a 12-month period from May 2004 to May 2005, the SPVC was implanted in 34 patients, of(More)
BACKGROUND The use of allografts or xenografts is the treatment of choice for pulmonary valve replacement. However, the limited durability is responsible for multiple reoperations associated with increased morbidity. In search of a definitive solution, the implantation of a mechanical valved conduit might be an option in highly selected patients. This study(More)
