By ΜΗΝΑΣ ΟΙΚΟΝΟΜΙΔΗΣ

Abstract

THE MITRAL AND TRICUSPID COMPONENTS OF THE FIRST HEART SOUND WERE STUDIED IN 13 CASES OF ATRIAL SEPTAL DEFECT PRE-AND POSTOPERATIVELY.BOTH COMPONENTS OF THE FIRST HEART SOUND (M1 T1) SHOWED AN ABNORMAL INTENSITY DISTRIBUTION. THE TRICUSPID COMPONENT HAS LOUD IN ALL CASES OF ATRIAL SEPTAL DEFECT AND WAS DETECTED AT THE TRICUSPID AND MITRAL AREAS,AS WELL AS THE ANTERIOR AND MID AXILLARY LINE AT FIFTH INTERCOSTAL SPACE TO THE LEFT.AT THE MITRAL AREA, THE ANTERIOR AND MID AXILLARY LINE T1 WAS LOUDER THAN M1 IN 11/13,8/13,THE 4/8 CASES RESPECTIVELY.THE MITRAL COMPONENT OF THE FIRST SOUND IN ASD'S SHOWED DIMINISHED INTENSITY.ITS MAXIMAL INTENSITY APPEARED EITHER AT THE ANTERIOR OR THE MID AXILLARY LINE.FOLLOWING CLOSURE OF THE ATRIAL SEPTAL DEFECT,M1 INCREASED AND T1 DECREASED IN INTENSITY.IN POSTOPERATIVE CASES THE TRICUSPID COMPONENT REMAINED ABNORMAL AND APPEARED LOUDER THAN M1 IN 7/13 CASES AT THE MITRAL AREA.ATTHE ANTERIOR AND MID AXILLARY LINE THE RELATION OF M1 TO T1 CHANGED AND M1 APPEARED LOUDER THAN T1.THE PHONOCARDIOGRAFIC AND AUSCULTATORY FINDINGS IN THIS STUDY ARE IN AGREEMENT AND SUPPORT THE VALVULAR ORIGIN OF THE TWO MAJOR COMPONENTS (M1 AND T1) OF THE FIRST HEART SOUND.
