Aim and objectives: The objective of this study is to determine the thickness difference
between the adult human heart's right and left ventricles, as well as their clinical importance
in the eastern Indian population, and compare it to the incidence in other races throughout the
world.
Introduction: Heart is a muscular motor that supplies blood to all parts of the body so that it
provides oxygen and nutrients to all the body parts. As we all know that this heart muscle
consists of four chambers viz., right atrium, right ventricle, left atrium and left ventricle. The
right ventricle receives from the right atrium and pumps the deoxygenated blood to the lungs.
The left ventricle directly pumps oxygenated blood to the rest of the body parts. The left
ventricle is usually narrower and longer than the right ventricle which extends from its base
of the atrio-ventricular groove to the cardiac apex. Moreover, the left ventricle walls are three
times thicker (8 – 12 mm) than those of the right ventricle which is relatively thin measuring
3 – 5 mm and the ration of the thickness between left to right ventricle is 3:1. There are four
borders of the heart. The right border is completely formed by the right atrium. The inferior
border is formed by the left & right ventricle. The left border is being formed by left ventricle
and little contribution from left atrium. Finally, the superior border is formed by right and left
atrium with the great vessels.

The aim of our study was to study the features of impaired left ventricular diastolic function in patients with chronic heart failure, depending on the clinical course of the disease. A total of 131 patients with CHF of ischemic origin with I, II and III FC CHF (men aged 38-60 years, mean age 54.51 ± 6.89 years) were examined. Patients with FC I were 31 (23.7%) patients, with FC II - 51 (38.9%) and FC III - 49 (37.4%) patients. The structural
and functional state of the myocardium and the process of LV remodeling were assessed by echocardiography with Doppler ultrasonography. EchoCG was performed on the device "MEDISON ACCUVIX V20" (South Korea), using a 3.25 MHz transducer in standard echocardiographic positions, transthoracic method in accordance with the recommendations of the American Society of Echocardiography (ASE). In patients with CHF, diastolic function disorders were identified in 74.8% of cases: grade I (impaired relaxation) was recorded in 38.9% (51 patients), grade II - (pseudonormal) in 21.4% (28), type III (reversible restrictive) - in 14.5% (19) patients. An analysis of the grades of diastolic dysfunction showed the predominance of relaxation disorders in 52% of patients and an increase in the number of patients with restrictive type of diastolic dysfunction with an increase in CHF FC. Thus, in 74.8% of CHF patients, impaired LV diastolic function was observed, characterized by its deterioration with the progression of the disease. At the same time, impaired LV diastolic function was characterized to a greater extent by impaired relaxation, and with the progression of the disease, a restrictive type of LVDD impairment.
