Diastolic dysfunction (DD) remains a diagnostic challenge, not for lack of available parameters, but because uncertainty emerges when complex physiology is reduced to static labels in echocardiographic reports. In clinical practice, physicians are often less concerned with the specific grade of DD and more interested in its prognostic implications and in whether increased filling pressures may explain dyspnea, guide further investigation, and support therapeutic decisions. It is precisely in this variable, mean left atrial pressure (MLAP) and left ventricular (LV) […]
