Cardiac Murmurs and Maneuvers An algorithm demonstrating the effect of various maneuvers on systolic murmurs. TR, tricuspid regurgitation; PS, pulmonary stenosis; MVP/MR, mitral valve prolapse/mitral regurgitation; HOCM, hypertrophic obstructive cardiomyopathy; MR, mitral regurgitation; AS, aortic stenosis; VSD, ventricular septal defect. The effect of squatting on AS may be variable (decreased, no change, or even increased) depending on the relative alteration of preload and afterload. Dr. Jay Mohan, D.O.
