The value of left parasternal impulse recordings in the assessment of mitral regurgitation

The clinical and diagnostic features of mitral valve disease

Mitral valve disease remains common, and requires regular clinical and echocardiographic review. Surgery is indicated soon after the development of symptoms or at the first sign of left ventricular decompensation in mitral regurgitation or of the right ventricle in mitral stenosis.

The physiologic mechanisms of cardiac and vascular physical signs

Examination of the heart and circulation includes five items: 1) the patient's physical appearance, 2) the arterial pulse, 3) the jugular venous pulse and peripheral veins, 4) the movements of the heart--observation, palpation and percussion of the precordium, and 5) auscultation. This report deals with specific examples that relate cardiac and vascular physical signs to their mechanisms, focusing on each of the five sources. It draws liberally on early accounts, emphasizing that modern investigative techniques often serve chiefly to verify hypotheses posed in the past.
