Case 1• 78 yr old male with a history of an ischemic
cardiomyopathy• s/p PCI RCA• Admitted to the hospital 3 times in the past 4
months for heart failure exacerbations• s/p upgrade of ICD to CRT-D with residual
dyspnea • h/o prior CVA, COPD, Afib• STS Score=10.9%• Cath: Occluded distal LCX, 90% lesion in
PDA, patent RCA stents
Cardiac Meds
• Amiodarone 200 mg daily• Nebivolol 20 mg daily• Furosemide 80- mg daily• Isosorbide mononitrate 60 mg daily• Spironolactone 25 mg daily• Warfarin 5 mg daily• Pravastatin 40 mg daily
Physical Exam
• BP: 120/68, HR=70• JVP=8-10 cm• Lungs: Clear• Cor: Inferolat displaced PMI; RRR; 2/6 systolic
murmur at apex• Abd: Soft, NT. No HSM or ascites• Ext: No edema

• What can we offer this patient?Medical therapy?Surgery?Mitra Clip?
COAPT TRIAL
• A clinical trial designed to study the safety and effectiveness of the MitraClip® device in heart failure patients who have functional mitral regurgitation (MR) and are not appropriate for mitral value surgery.
• Patients randomly assigned to a Device Group or Control Group
Followup
• Addition of lisinopril 10 mg daily• PCI of PDA• 5 months later: c/o fatigue, SOB improved
Echo 5 months later
LVEDV=184 mlLVESV=109 mlEF=40%
Case 2• 67 yr old male with h/oMi (PDA) 1 yr prior• MI complicated by cardiogenic shock and MR• Improved with medical therapy• Recently admitted multiple times with
decompensated heart failure• h/o Afib• CKD (GFR=40)• Meds:
– Bumetanide 1 mg BID– Lisinopril 10 mg daily– Warfarin 5 mg daily– Metoprolol 100 mg daily– Atrovastatin 20 mg daily– ASA 81 mg daily
Physical Exam
• BP=110/82, HR=78• JVP<10 cm• Lungs: Decreased BS right base• Cor: Irreg irreg rhythm, 2/6 systolic murmur at
apex• Abd: No HSM or ascites• Ext: 1+ edema

Followup
