Among 2,247 operatively excised stenotic aortic valves in adults aged >20 years without associated mitral stenosis or mitral valve replacement, 1,608 valves were weighed; 1,241 (77%) weighed <4 g, and 367 (23%) weighed >= 4 g. Of the valves from 1,038 men, 717 (69%) weighed <4 g, and 321 (31%) weighed >= 4 g; of the valves from 570 women, 524 (92%) weighed <4 g, and 46 (8%) weighed >= 4 g. The patients see more with heavier (>= 4 g) valves had higher transvalvular peak gradients (78 +/- 28 vs 55 +/- 27 mm Hg, p < 0.0001), smaller valve areas (0.69 +/- 0.30 vs 0.75 +/- 0.27 cm(2), p < 0.0001), and more often congenitally malformed valves (327 of 367 [89%] vs 638 of 1,241 [51%],
p < 0.0001). In GS-7977 patients aged 81 to 90 years, 44 of the 195 valves (23%) were congenitally unicuspid or bicuspid; in those aged 41 to 50 years, 112 of 128 valves (88%) were congenitally malformed. In conclusion, compared
with patients whose stenotic aortic valves weighed <4 g, those with valves weighing >= 4 g were younger, had higher transvalvular peak systolic pressure gradients, had smaller valve areas, and usually (about 90%) had congenitally unicuspid or bicuspid valves. It seems reasonable to avoid percutaneous aortic valve implantation in patients with heavily calcified stenotic aortic valves, most of which are either congenitally unicuspid or bicuspid.

“Objective To determine the value of echocardiography JNK-IN-8 ic50 in predicting response to cardiac resynchronisation therapy (CRT).\n\nMethods This is a prospective randomised study that recruited patients with (group 1) and without (group 2) echocardiographic evidence of mechanical dyssynchrony. 73 heart failure patients (NYHA III-IV) with a requirement for an implantable cardioverter defibrillator, QRS >= 120 ms and LV ejection fraction (EF) < 35% were studied. Group 1 patients received CRT-D
(26 patients). Group 2 patients were randomised to CRT-D (group 2a: 23 patients) or implantable cardioverter defibrillator (group 2b: 21 patients). Main outcome measures were peak oxygen consumption (VO(2)max), NYHA class, and echocardiography at baseline and at 6 months.\n\nResults 62% of group 1 patients achieved >= 1 ml/kg/min increase in VO2max at 6 months versus 50% in group 2a and 21% in group 2b (p=0.04). Group 1 patients showed significant improvements in VO2max (15.8 +/- 2 to 18.0 +/- 4 ml/kg/min, p=0.01), NYHA class (3.1 +/- 0.3 to 1.9 +/- 0.7, p<0.001) and EF (22 +/- 7% to 26 +/- 9%, p=0.02). Group 2a showed significant improvement in NYHA class (3.1 +/- 0.3 to 2.2 +/- 0.7, p<0.001) but no change in EF or VO(2)max. Group 2b showed no change in NYHA class or EF with a decline in VO(2)max (16.4 +/- 4 to 14.1 +/- 4, p=0.03).
