OBJECTIVES•Understand the diagnostic pathway for determining patient eligibility for percutaneous mitral interventions•Discuss discrepant results that have been reported in recent mitral intervention studies•Review the routine follow-up of patients post-mitral clip procedures

CASEPRESENTATION
Is this a reasonable patient for transcatheter mitral repair?
QUESTION#1What is NOT an important factor to consider when selecting a patient for transcatheter mitral repair (MitraClip)?A.Ejection FractionB.Severity of Mitral regurgitationC.Etiology of cardiomyopathyD.Current medical therapyE.Severity of Pulmonary HypertensionF.Severity of TR
EVALUATIONOFAPATIENTFORMITRACLIP•Clinical evaluation•Is the patient symptomatic?•Is there a reasonable chance that treating FMR will improve quality of life? Are the comorbidities prohibitive?•Transthoracic Echo•Severity of MR, LV Function, Coexistent valvular heart disease•RV function•Transesophageal Echo•Mechanism of MR•Mitral valve area
CASEPRESENTATION
•Patient discussed at Heart Team meeting decision made to propose COAPT Trial•Patient consented for participation in the COAPT Trial (12/2016) and randomized to medical therapy
CASEPRESENTATION•Twelve months following randomization to Medical Therapy in COAPT:•Hospitalized for decompensated heart failure on 18separate occasions (January 2017-December 2017)•Renal function deteriorating, creat400•NYHA IV

QUESTION#2What does the evidence from MITRA-FR and COAPT suggest about the utility of MitraClip in secondary MR?A.There is no benefit of MitraClip in secondary MRB.Treatment with MitraClip reduces HF hospitalizations in ALL patients with secondary MRC.Treatment with MitraClip reduces all cause mortality in ALL patients with secondary MRD.There is benefit of MitraClip in selected patients with secondary MRE.Proportionately severe MR is a characteristic of those who benefit from MitraClip

•KEY MESSAGES:•Populations were different (very dilated LV vs. less dilated)•MR Severity was different (moderate MR vs. severe MR)•Aggressive medical therapy titration was utilized in COAPT with no significant differences in medical therapy between groups•There was greater MR reduction in COAPT, 95% vs 83% with 2+ or less residual MR•Clinical benefit was seen in those patients with severe MR and dilated LV but not end-stage severe dilatation•In those patients with end-stage LV dilatation, treatment of moderate MR does not provide benefit (? Too late)

•For any given regurgitant fraction, the EROA is dependent on both the left ventricular end-diastolic volume (LVEDV) and the left ventricular ejection fraction (LVEF)
DISPROPORTIONATEVS. PROPORTIONATEMR
•Regurgitant volume is very dependant on LVEF in the setting of severe MR (RF 50%)•When the LVEDV is 220 to 250 ml, severe MR (defined by a regurgitant fraction of 50%) corresponds to a regurgitant volume of 45 ml when the LVEF is 40%, 35 ml when the LVEF is 30%, and <25 ml when the LVEF is 20%.

PROPORTIONATEMR•COAPT enrolled patients with disproportionatelysevere MR •MITRA-FR enrolled patients with proportionatelysevere MR•The totality of available evidence suggests that patients with chronic heart failure respond favorably to transcatheter mitral valve repair IF they exhibit degrees of MR that are disproportionately greater than might be expected from the degree of LV chamber enlargement.

guidance on communication techniques to support these
decisions. Its goal is primarily to help healthcare providers of
all types integrate these concepts into their routine practice to
promote the delivery of effective, safe, efficient, timely,
equitable, and patient-centered care. 12
We recognize that
major barriers to the implementation of these concepts are
time, training, and resources. We also recognize the limited
and inequitable access to experts with formal training in heart
failure and palliative care, which leaves many of these
responsibilities to be borne by healthcare providers in a
general medical setting. If the goals of this document are to be
realized, however, the healthcare system will need to make a
fundamental commitment to shared decision making, with
realignment of incentives to support the tailoring of advanced
care to individual patients. Without changes in the structure
of the healthcare team and associated reimbursement, these
recommendations will remain an unfunded mandate that are
unlikely to be fully realized in most practice settings.
Expectations for the Future
● Attention to the clinical trajectory is required to calibrate
expectations and guide timely decisions.
● Predictive models can target high-risk populations but
leave wide uncertainties around estimates of survival for an
individual.
● Difficult discussions now will simplify difficult decisions
in the future.
● Uncertainty is inevitable and should be included in discus-
sions with patients and family.
Estimating Prognosis in Heart Failure
Assessment of prognosis is the foundation for selection
among therapies for life-threatening disease, but this is
particularly challenging for heart failure. The clinical course
varies dramatically across the spectrum of disease severity
and is relatively unpredictable for individual patients (Figure
1). 19,21
This contrasts with the more linear decline of patients
with advanced cancer, which has traditionally been the model
for approaches to end-stage disease. Even late in heart failure,
patients often enjoy “good days” and brief interludes of
apparent stability, which can lull them and their care provid-
ers into postponing vital decisions. Prognosis is further
clouded by the unique contrast between unexpected sudden
death (ie, lethal arrhythmia) and lingering death with conges-
tive symptoms (ie, progressive pump failure). Frequent reap-
praisal of the clinical trajectory helps calibrate expectations,
guide communication, and inform rational decisions.
More than 100 variables have been associated with mor-
tality and rehospitalization in heart failure. 22–27
Examples of
prognostic factors include demographics (age, sex, race,
insurance status), functional status (New York Heart Associ-
ation functional class and health-related quality-of-life
scores), exercise capacity (peak oxygen consumption,
6-minute walk), cardiac structure and function (cardiac cham-
Figure 1. A depiction of the clinical course of heart failure with associated types and intensities of available therapies. Black line:
Patients tend to follow a progressive, albeit nonlinear, decline in health-related quality of life as the disease progresses; this course can
be interrupted by sudden cardiac death caused by arrhythmia or can end in a more gradual death caused by progressive pump failure.
Gray line: At disease onset, multiple oral therapies are prescribed for cardiac dysfunction and/or treatment of comorbidities. As disease
severity increases, the intensity of care may increase in parallel, with intensification of diuretics, addition of an implantable cardioverter-
defibrillator/cardiac resynchronization therapy for those eligible, and increasing interaction with the medical system through ambulatory
visits and hospitalizations, until the time when standard therapies begin to fail (transition to advanced heart failure). Dotted line: Pallia-
tive therapies to control symptoms, address quality of life, and enhance communication are relevant throughout the course of heart fail-
ure, not just in advanced disease; palliative therapies work hand in hand with traditional therapies designed to prolong survival. The
critical transition into advanced heart failure from the medical perspective is often followed by a transition in goals of care from the
patient and family perspective, wherein palliative therapies may become the dominant treatment paradigm (for the majority of patients
in whom transplantation and mechanical circulatory support are not an option). Clinicians must recognize the transition to advanced
heart failure so that therapeutic options can be considered in a timely fashion and patients are able to proactively match medical deci-
sions to clinical realities. CHF indicates chronic heart failure; MCS, mechanical circulatory support. Modified from Lanken et al; 21
