Clinical application of stress echocardiography in valvular heart disease

ABSTRACT Valvular heart diseases (VHDs) constitute an increasing problem both as a consequence of population aging and as the sequelae of other heart diseases. Accurate diagnosis is essential for correct clinical decision‑making; however, in many patients, transthoracic and transesophageal echocardiography is insufficient. Stress echocardiography (SE) proved to be a useful tool allowing for simultaneous assessment of left ventricular contractile reserve and HVD hemodynamics under conditions of physiological or pharmacological stress. It is recommended for assessing the severity of VHD, guiding the choice of treatment, as well as for surgical risk stratification. It can be applied both in asymptomatic patients with severe VHD and in symptomatic individuals with moderate disease. In patients with VHD, SE can be performed either as exercise stress echocardiography (ESE) or dobutamine stress echocardiography (DSE). The first modality is recommended to unmask symptoms or abnormal blood pressure response in patients with aortic stenosis (AS) who report to be asymptomatic or in those with mitral stenosis with discordance between clinical symptoms and the severity of valve disease on transthoracic echocardiography. In asymptomatic patients with paradoxical low‑flow, low‑gradient (LFLG) AS, ESE can be used to assess the severity of stenosis. On the other hand, low‑dose DSE can be a useful diagnostic tool in classical LFLG AS, providing information on stenosis severity and contractile reserve. Moreover, SE is indicated in patients with prosthetic valve when there is discordance between symptoms and echocardiographic findings. It is also recommended in high‑risk surgical patients with VHD with poor functional capacity and more than 2 clinical risk factors. The present paper discusses in detail the use of SE in VHD

Paediatric echocardiography in clinical practice. 2012 Recommendations of the Echocardiography Working Group of the Polish Cardiac Society

Echocardiography has become the primary imaging tool in the diagnosis and assessment of cardiological disorders in children. The purposes of this paper are to describe indications for paediatric echocardiography, define optimal instrumentation and laboratory setup for paediatric echocardiographic examinations and establish a baseline list of recommended measurements to be performed in a complete pediatric echocardiogram
