This study investigates the correlation of occlusive wedge pressure (WP) with direct left atrial (LA) pressure in patients with severe mitral regurgitation (MR) undergoing transcatheter mitral valve repair (TMVr) with MitraClip.
There is interest in acquiring objective hemodynamic parameters for intraprocedural guidance in patients undergoing MitraClip.
The purpose of this study is to describe the initial clinical experience with a steerable transseptal needle (STSN) for left‐sided structural heart procedures.
Targeted transseptal (TS) puncture is required for many structural heart procedures, and the use of a steerable needle has not previously been described.
Consecutive patients undergoing structural heart interventions...
Interstitial lung abnormality (ILA) is found in 5–10% of the general population and is associated with increased mortality risk. Risk factors for ILA, including advanced age and smoking history also increase the risk for aortic stenosis (AS). Transcatheter aortic valve replacement (TAVR) has become an increasingly utilized intervention for patients with severe AS, and requires a high-resolution computed...
Background Although the incidence of acute death related to coronary artery disease has decreased with the advent of new interventional therapies, myocardial infarction remains one of the leading causes of death in the US. Current animal models developed to replicate this phenomenon have been associated with unacceptably high morbidity and mortality. A new model utilizing the first diagonal branch...
This study investigated the time-dependent remodeling and growth potential of porcine small intestine submucosa as a biomaterial for the reconstruction of pulmonary arteries in a lamb model.Left pulmonary arteries were partially replaced with small intestine submucosal biomaterial in 6 lambs. Two animals each were humanely killed at 1, 3, and 6 months. Computed tomographic angiography, macroscopic...
