Morphologic, mechanical, conductive, and hemodynamic changes following transcatheter closure of atrial septal defect.

Objective: The secundum type of atrial septal defect (ASD) is a common congenital cardiac anomaly. Transcatheter closure of the defect is the preferable therapeutic approach to avoid potential future complications. This work extends the data collected so far regarding the electrocardiographic, morphologic, hemodynamic, and mechanical changes following the procedure.

Percutaneous transcatheter occlusion of the patent arterial duct using the pfm DuctOcclud Coil via a trans-aortic and trans-pulmonary approach.

Occlusion using coils is now the treatment of choice for closure of the patent arterial duct. The DuctOcclud (pfm AG, Cologne, Germany) device is a relatively new retrievable coil for such trans-catheter closure. This study expands on previously reported experience with this device, summarizes the advantages of the device, and compares trans-pulmonary and trans-aortic delivery in 47 patients.

Evaluation of inotropic changes in ventricular function by NOGA mapping: comparison with echocardiography.

Assessment of left ventricular (LV) function in the catheterization laboratory is important to optimize treatment decisions and guide catheter-based local therapies. NOGA electromechanical mapping was developed to assess LV contraction during catheterization; however, quantitative analysis of its "local shortening" (LS) algorithm and direct comparison with conventional methods are lacking. We evaluated the accuracy of NOGA-based regional and global function by examining its ability to detect pharmacologically induced changes in contractility compared with echocardiography.
