Abstract Background Classic low flow gradient aortic stenosis (LFLG-AS) represents 5-10% of the Aortic Stenosis (AS) population and is associated with poorer clinical outcomes when compared to other AS subtypes. The survival rate these patients (40–60% at 2-yrs) conservative management. TOPAS study found a transfemoral Transcatheter Valve Replacement (TAVR) adjusted hazard ratio (HR) 0.23 Surgical Repair HR 0.36. However, mortality within 2-yrs TAVR can still be as high 30%-50%. Currently...
Introduction Peak global myocardial work efficiency (GWE), a measure of peak constructive to wasted ratio, has been shown discriminate coronary ischemia during treadmill stress echocardiography (SE). We wanted assess additive utility longitudinal strain (GLS), index (GWI), and GWE in improving positive predictive value (PPV) an abnormal dobutamine (DSE) calculate cost-savings by avoiding secondary tests. Methods prospectively enrolled patients with DSE who underwent confirmatory tests...
Previous studies have indicated the benefits of cardiac rehabilitation programs after major coronary artery disease (CAD) events. We studied 591 consecutive patients from two academic institutions before and completion a exercise training program to determine effects this therapy on capacity, indices obesity, plasma lipid values, behavioral characteristics, quality life parameters. After rehabilitation, statistically significant improvements occurred in capacity (+33%), percent body fat...
Left ventricular (LV) hypertrophy (LVH) is a known independent determinant of left atrial (LA) size; however, there controversy regarding whether the LV geometric patterns are associated with LA enlargement (LAE), major indicator diastolic heart failure. The authors evaluated 47,865 patients preserved ejection fraction to determine relationship geometry on LAE as determined by volume index (LAVi) 29 mL⁄m². Abnormal was identified in 48% and indentified 43% higher prevalence abnormal...
Abstract Purpose Degenerative mitral stenosis (DMS) is an increasingly recognized cause of stenosis. The goal this study was to compare echocardiographic differences between DMS and rheumatic (RMS), identify variables reflective severity, propose a dimensionless index (DMSI) for assessment severity. Methods This single‐center, retrospective cohort study. We included patients with at least mild MS mean transmitral pressure gradient (TMPG) ≥4 mm Hg. Mitral valve area by the continuity equation...
To determine the feasibility and accuracy of digital echocardiography for routine interpretation two-dimensional Doppler echocardiography, we studied 93 consecutive patients chosen at random from our daily workload. The parameters included cavity sizes, biventricular regional global systolic diastolic function, valvular structure presence or absence pericardial disease. results were first interpreted using quad screen, format cine loops. These then compared with obtained reviewing video-tape...
