CardioNerds correspondents Drs. Akiva Rosenzveig and Jenna Skowronski, along with expert faculty Dr. Randall Starling, Cleveland Clinic, tackle the following hypothetical case study pertaining to heart failure management.
Mrs. M is a 65-year-old woman with non-ischemic dilated cardiomyopathy (LVEF 40%) and moderate to severe mitral regurgitation (MR) presenting for outpatient follow-up. Despite improvement overall, she continues to experience dyspnea on exertion with two flights of stairs and occasional PND. She reports adherence with her medication regimen of sacubitril-valsartan 97-103mg twice daily, metoprolol succinate 200mg daily, spironolactone 25mg daily, empagliflozin 10mg daily, and furosemide 80mg daily. A transthoracic echocardiogram today shows an LVEF of 35%, an LVESD of 60 mm, severe MR with a regurgitant fraction of 60%, and an estimated right ventricular systolic pressure of 40 mmHg. Her EKG shows normal sinus rhythm at 65 bpm and a QRS complex width of 100 ms.
What is the most appropriate recommendation for management of her heart failure?
