Abstract

Assessment of Right ventricular func􀆟 on plays a major role
in the Evalua􀆟 on of Atrial Septal Defect. The introduc􀆟 on
of Doppler measurement of myocardial wall veloci􀆟 es (􀆟 ssue
Doppler imaging; TDI) and the recent development of strain
rate imaging (SRI) technique have made a more adequate
assessment of global and regional systolic and diastolic RV
func􀆟 on possible. This study was conducted to evaluate the
RV func􀆟 on by using newer echocardiographic indices such as
Tissue Doppler Imaging & Strain Rate Imaging. A prospec􀆟 ve
study was conducted among 64 adult pa􀆟 ents admi􀆩 ed for
ASD device closure in the department of cardiology at Narayana
Ins􀆟 tute of Cardiac Sciences (NICS) Bangalore. A basic apical
4chamber (A4CH) view was taken during echocardiography
in which the 􀆟 ssue mo􀆟 on velocity is superimposed for real
􀆟 me colour display. TDI annular veloci􀆟 es during systole, early
relaxa􀆟 on (Ea), and atrial systole (Aa) were possessed from
RV free wall (FW) and inter ventricular septum at basal site in
the A4CH view. Decelera􀆟 on 􀆟 me (DT), isovolumic relaxa􀆟 on
􀆟 me (IVRT), isovolumic contrac􀆟 on 􀆟 me (IVCT) and ejec􀆟 on
􀆟 me (ET) were measured. For the analysis of global RV
func􀆟 on, Doppler parameters are used to derive the Tei index
i.e. (IVCT+IVRT)/ET. The stain and strain rate was es􀆟 mated
from the RV focused AP4CH view from 􀆟 ssue Doppler data,
by calcula􀆟 ng the velocity gradient. All these measurements
were taken pre and post ASD closure. Data was analyzed by
descrip􀆟 ve sta􀆟 s􀆟 cs and Wilcoxon sign rank test was used
to fi nd out pre and post procedural comparison. The study
showed signifi cant decrease in 􀆟 ssue Doppler parameters
including annular velocity, strain and strain rate during
immediate post device closure and increase a􀅌 er 1 month of
closure. The RV func􀆟 on improved signifi cantly post 1 month
of closure compared with post 24 hours.
