Semi-continuous left atrial pressure measurements during mitral valvotomy.
or fracturing the commissures, but, as far as can be ascertained, few papers give detailed information about the merits of these pressure readings. In an earlier report from this hospital Pedersen and Tybjaerg Hansen (1953) published measurements from the left atrium in 15 cases. In 12 cases of valvotomy for mitral stenosis without significant regurgitation a decrease of pressure was recorded i...
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 کاملDirect left atrial pressure tracings and the degree of mitral obstruction.
Attempts have been made to assess the degree of mitral obstruction in mitral stenosis by analysing the diastolic part of indirect left atrial pressure tracings (Owen and Wood, 1955). These pressure tracings have been obtained using a cardiac catheter in the pulmonary artery in the " wedge " position, and available evidence suggests that direct left atrial pressure tracings are comparable to ind...
متن کاملDirect Left Atrial Pressure Monitoring in Severe Heart Failure: Long-Term Sensor Performance
We report the stability, accuracy, and development history of a new left atrial pressure (LAP) sensing system in ambulatory heart failure (HF) patients. A total of 84 patients with advanced HF underwent percutaneous transseptal implantation of the pressure sensor. Quarterly noninvasive calibration by modified Valsalva maneuver was achieved in all patients, and 96.5% of calibration sessions were...
متن کاملImpact of Atrial Fibrillation Ablation on Left Ventricular Filling Pressure and Left Atrial Remodeling
BACKGROUND Left ventricular (LV) diastolic dysfunction is associated with new-onset atrial fibrillation (AF), and the estimation of elevated LV filling pressures by E/e' ratio is related to worse outcomes in patients with AF. However, it is unknown if restoring sinus rhythm reverses this process. OBJECTIVE To evaluate the impact of AF ablation on estimated LV filling pressure. METHODS A tot...
