Abstract:
Objective To analyze the characteristics and influencing factors of coronary sinus(CS) dilation in patients with primary pulmonary hypertension(PPH) and persistent left superior vena cava(LSVC). Methods Control group included twenty-two normal subjects [mean age ( 40.6 ? 10.6 ) years],PPH group included twenty-six patients with PPH [mean age ( 41.9 ? 11.4 ) years] and LSVC group included thirty-three patients with LSVC [mean age ( 30.9 ? 15.8 ) years]. After the standard apical four-chamber view was obtained,the transducer was tilted backward to direct ultrasonic beam towards the left atrioventricular groove,then the distal part of the CS could be exposed. Echocardiographic parameters of the CS included end-systolic diameter of CS orifice(CSOESD),end-diastolic diameter of CS orifice(CSOEDD),the ratio of CSOESD to CSOEDD (CSOESD/EDD). Results CSOESD,CSOEDD were larger [CSOESD ( 12.56 ? 3.58 )mm vs ( 8.47 ? 2.32 )mm,P
