Even in early aortic stenosis there is no gradient at rest ... helps normalize wall stress and maintain cardiac output in the normal range. Since there is little hemodynamic consequence to ...

Objective We aimed to describe the progression rate into manifest aortic stenosis (AS) in subjects with normal aortic valves or in an early phase of calcific aortic valve disease. Methods Participants ...

In healthy individuals with a normal valve, minimal energy is required ... Additionally, the LV-aortic gradient decreases with progressively increasing LV systolic dysfunction.

Patients with low-gradient aortic stenosis and reduced LVEF, compared with patients with high-gradient aortic stenosis, have worse clinical outcomes.

The chest radiography may reveal a normal cardiac size since ... Doppler is used to quantify the severity of aortic stenosis by measuring the pressure gradient across the aortic valve and by ...

In Revista Española de Cardiología, González-Cánovas et al.1 reported the results of a study that examined whether severe aortic stenosis (AS) with low-gradient ...

Chest radiography may reveal a normal cardiac size since ... At cardiac catheterization for aortic stenosis, the transvalvular pressure gradient is determined by directly recording ascending ...

Echocardiogram showed normal left ventricle ejection fraction and aortic valve structure without gradient. CT angiography (figure 2) of the chest further defined an elongated aortic arch, luminal ...

S-T segment depression is mainly caused by aortic valve pressure gradient, it therefore improves immediately after AVR; T wave amplitude reduction is, however, resulted from LVH, and it improves only ...

Pseudocoarctation of the aortic arch is an infrequent congenital anomaly which ... the descending aorta at the level of the ligamentum arteriosum lacking a pressure gradient across the lesion.1 2 This ...

In Revista Española de Cardiología, González-Cánovas et al.1 reported the results of a study that examined whether severe aortic stenosis (AS) with low-gradient ...
