Systemic sclerosis is a connective tissue disease characterized by wide-spread vascular lesionsand fibrosis of the skin and internal organs. It is an immune mediated rheumatic disease with thepresence of an immunological dysfunction of T lymphocytes, especially Th1 and Th17 subtypes. Itaffects gastrointestinal, pulmonary, vascular, musculoskeletal, cardiac and various other systems.This disease is rare but has high morbidity and mortality with less known effective management. Wereport a case of 70-year-old female with systemic sclerosis presented with pain along with swellingover multiple joints since 18 months which exacerbated since last 6 months and wound over fingertips since last 2 weeks. We present here other various signs, investigations and management of thisuncommon disease systemic sclerosis, also known as scleroderma. Various systems are evident tobe involved including cardiac (left ventricular diastolic dysfunction) and peripheral vascular system(Raynaud’s phenomenon).

Diastolic dysfunction is the impairment of the filling in the left ventricle. Patients with left ventricular diastolic dysfunction (LVDD) lose the ability to adjust left ventricular filling properties without increasing left atrial pressure [1]. Although LVDD is very prevalent, it currently remains difficult to diagnose due to inherent atrioventricular compensatory mechanisms including increased heart rate, increased left ventricular (LV) contractility, and increased left atrial (LA) pressure. Although variations within the early diastolic filling velocity have been previously observed [2], the physical mechanism for the deceleration of the early filling wave is not understood.
