Abstract Background Handheld echocardiography devices(HH) arise as a common tool in clinical examination and screening for various cardiovascular disorders. Despite of it, studies with this method are small, with unselected patients and limited scope of diagnostic comparison. Purpose Assess the usefulness of the new miniaturized HH and compare its concordances with the standard high definition echocardiography study(STD). Methods Between April and May of 2016 adult patients who were scheduled to regular STD, were also submitted to a HH exam. Experienced sonographers performed and an experienced echocardiographer reviewed the STD exam, and an experienced echocardiographer performed and reviewed the HH study - reviewers were blinded to the other study results. STD exams included 2-dimensional images, Color Doppler and hemodynamics analysis. With the HH hemodynamic assessment was not performed as the machine does not include such technology. Agreement between the reports was analyzed. Results 110 patients were included. Mean age was 62.4 ± 16.7 years. The κ values(Table) show good correlation between HH and STD on the analysis of left ventricular global and segment functions, right ventricle size and function, mitral and aortic stenosis. On the evaluation of left ventricle hypertrophy, mitral and aortic regurgitations the correlation was modest, while poor correlation was found for pulmonary and tricuspid regurgitations. Conclusion In a daily practice scenario with experienced hands, HH demonstrates good results for the assessment of ventricles size and function, while the evaluation of right heart valves was the least reliable performance. Dissemination of HH should occur with considerations and caution.

AbstractLow-flow low-gradient aortic stenosis (LFLG AS) with reduced left ventricle ejection fraction (LVEF) is still a diagnostic and therapeutic challenge. The aim of this paper is to review the latest evidences about the assessment of the valvular disease, usually difficult because of the low-flow status, and the therapeutic options. Special emphasis is given to the available diagnostic tools for the characterization of LFLG AS without functional reserve at stress echocardiography and to the factors that clinicians should evaluate to choose between surgical aortic valve repair, transcatheter aortic valve implantation, or medical therapy.

BACKGROUND The papillary muscle basal connections have significant clinical implications. Variety of studies done on its morphology and function by various specialists in different departments. A close look on these revealed the interconnections of papillary muscles to one another and to the interventricular septum of both ventricles is related to uncoordinated contractions of papillary muscles, leading to hyper or hypokinesia or prolapse or even its rupture. METHODS Our study done in 25 formalin soaked hearts revealed after the deep and meticulous dissection, reflecting the walls of ventricles laterally the numerous interconnections of papillary muscles at its bases and IVS. Ventricles are opened by inverted ‘L’ shaped incision and its reflected more laterally till all the papillary muscles is visible in one frame after incising the moderator band. The connections were noted, measured, photographed, tabulated, compared with similar studies and analysed with experts with respective fields. RESULTS Almost all the specimens did have the interconnections. Further the post mortem findings of the cardiac related deaths with involvement of papillary muscles suggest damage to such ‘bridges’. The moderator band extensions to the base of right APM, and its extension to the posterior groups is noted in all the specimens. The bridge from the IVS to bases of both the groups of papillary muscles is noted in left ventricle. In90% of specimens the one PPM is found to be loosely connected, more so in left ventricle. CONCLUSIONS We are of a conclusion that such basal interconnections and to the interventricular septum are responsible for rhythmic contractions of papillary muscles of both ventricles. Since the AV valves have to open simultaneously, interconnections becomes mandatory as the impulse has to reach it before it reaches the trabeculae carniae. One of the Posterior papillary muscles is loosely connected to other papillary muscles, may be the reason for its rupture, more so in left ventricle.
