A woman in her 70s was referred to our centralized heart failure management program because of New York Heart Association functional class III heart failure with preserved left ventricular systolic function and recurrent hospitalizations for heart failure. Her medical history was remarkable for coronary artery disease after coronary artery bypass grafting, chronic stable angina, severe tricuspid regurgitation, atrial fibrillation, and obesity with a body mass index of 39 (calculated as weight in kilograms divided by height in meters squared). After screening and medication optimization, she underwent successful implantation of a small sensor-pressure device (CardioMEMS; Abbott) into her pulmonary artery without complication. Her home medications included torsemide, metolazone, metoprolol succinate, spironolactone, isosorbide mononitrate, diltiazem, and ranolazine. Her initial postimplantation sensor readings and waveforms are shown in Figure 1A.
