The Giant " A " Wave of the Left Atrial
IN an exploration of the left atrium via an atrial septal defect during a recent cardiac catheterization in this laboratory, the catheter tip entered the left atrial appendage. An exaggerated "a" wave observed in the pressure contour from the left atrial appendage was striking and exceeded in amplitude the "a" wave from the left atrium proper. Following a similar observation shortly thereafter ...

متن کاملEnlarged Right Atrium Falsely Interpreted as a Mediastinal Mass: A Case Report
Right atrial dilation due to left heart disease is a common complication among adults. The present review aimed to describe a case of massively dilated right atrium in a female patient presenting with valvular heart disease and no atrial fibrillation. The results of chest X-ray revealed a large opacity filling the lower right hemithorax, falsely interpreted as a mediastinal mass. During the tra...
متن کاملA Semi-Automated Algorithm for Segmentation of the Left Atrial Appendage Landing Zone: Application in Left Atrial Appendage Occlusion Procedures
Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
متن کاملاندازه گیری فشار شریان ریوی توسط داپلر و مقایسه آن با روش کاتتریسم
Pulmonary artery pressure can be estimated from right ventricular-right atrial pressure gradient in patients with tricuspid regurgitation. The most common approach is to estimate pulmonary artery systolic pressure from right ventricular pressure (assuming no pulmonic stenosis) determined as the sum of the right ventricular-right atrial pressure gradient and either an assumed or clinically deter...
