Traditional Areas of Auscultation Mitral Area –Cardiac Apex Tricuspid Area-4 th & 5 th intercostal space of left sternal border Aortic Area-2 nd intercostal space of the right sternal border Pulmonic Area-2 nd intercostal space left sternal border

Left Ventricular Area Aortic component of the 2 nd heart sound A 2 Cardiac Apex and extends laterally in the 3rd and 4th interspaces to left sternal border in one direction & to the anterior axillary line in the other.

Right Ventricular Area Tricuspid Stenosis or regurgitation, pulmonary regurgitation and ventricular septal defect.
