Central Sleep Apnea in Patients due to Severe Aortic Stenosis

Table 1

Clinical, hemodynamic, echocardiographic, and sleep data before and after aortic valve replacement (AVR). BMI: body mass index, AVA: aortic valve area, EF: ejection fraction, LVID(d/s): left ventricular diameter (end diastolic/end systolic), LVPWd: left ventricular posterior wall thickness, PAM: mean pulmonary artery pressure, LVEDP: left ventricular enddiastolic pressure, SDB: sleep disordered breathing, AHI: apnea/hypopnea-index.
