Sleep Apnea, Septal Myectomy, and the Valsalva/Mueller Maneuvers: Who Can Resist Loving Hemodynamic Physiology?

Patients with hypertrophic cardiomyopathy (HCM) represent a unique group of cardiovascular patients because common indicators of cardiomyopathy progression may be of limited utility in HCM (left ventricular ejection fraction), while other individualized measures have been identified to predict adverse outcomes (left atrial size, atrial and ventricular arrhythmias, septal thickness, peak oxygen consumption). The distinctive aspects of obstructive HCM pathophysiology can test the clinician ’s skills during auscultation maneuvers as well as during unique management decisions (restrictions in the use of afterload reducing agents, adrenergic pressors).
