Practical Applications of Concomitant Pulmonary Vein Isolation and Left Atrial Appendix Closure Device Implantation.

Pulmonary vein isolation (PVI) using cryoballoon causes acute tissue edema of the osteal region of the pulmonary veins and the left atrium. In two cases combining PVI with an implantation of a left atrial appendage closure device led to malsizing of the device, device shouldering, and a paraprosthetic residual flow. ().

Comparison of the Effect of 5 Different Treatment Options for Managing Patellar Tendinopathy: A Secondary Analysis.

Objective: Currently, no treatments exist for patellar tendinopathy (PT) that guarantee quick and full recovery. Our objective was to assess which treatment option provides the best chance of clinical improvement and to assess the influence of patient and injury characteristics on the clinical effect of these treatments.

Design: A secondary analysis was performed on the combined databases of 3 previously performed double-blind randomized controlled trials.
