Secondary mitral regurgitation (SMR) is a common occurrence in patients with heart failure with reduced ejection fraction. Moderate-severe or severe SMR is associated with increased mortality and hospitalisations from heart failure. Medical and cardiac resynchronisation therapies have been the only treatments proven to improve prognosis in this patient population. The Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy (COAPT) and the Percutaneous Repair with the MitraClip Device for Severe Functional/Secondary Mitral Regurgitation (MITRA-FR) RCTs evaluated transcatheter mitral valve repair with MitraClip for treatment of SMR in addition to medical therapy and they had divergent results. The COAPT trial demonstrated that a reduction in SMR with MitraClip resulted in reduced mortality and heart failure hospitalisations along with improved symptoms and quality of life in appropriately selected patients. The MITRA-FR trial did not show any benefit from using MitraClip for patients with SMR. This article summarises the differences in these two trials and suggests a contemporary approach to the management of SMR.

Approximately half of all patients with heart failure (HF) have a preserved ejection fraction, and the prevalence is growing rapidly given the aging population in many countries and the rising prevalence of obesity, diabetes, and hypertension. Functional capacity and quality of life are severely impaired in heart failure with preserved ejection fraction (HFpEF), and morbidity and mortality are high. In striking contrast to HF with reduced ejection fraction, there are few effective treatments currently identified for HFpEF, and these are limited to decongestion by diuretics, promotion of a healthy active lifestyle, and management of comorbidities. Improved phenotyping of subgroups within the overall HFpEF population might enhance individualization of treatment. This review focuses on the current understanding of the pathophysiologic mechanisms underlying HFpEF and treatment strategies for this complex syndrome. Expected final online publication date for the Annual Review of Medicine, Volume 73 is January 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

ObjectivesTo gather insights on the disease experience of patients with heart failure (HF) with reduced ejection fraction (HFrEF), and assess how patients’ experiences and narratives related to the disease complement data collected through standardised patient-reported outcome measures (PROMs). Also, to explore new ways of evaluating the burden experienced by patients and caregivers.DesignObservational, descriptive, multicentre, cross-sectional, mixed-methods study.SettingSecondary care, patient’s homes.ParticipantsTwenty patients with HFrEF (New York Heart Association (NYHA) classification I–III) aged 38–85 years.MeasuresPROMs EuroQoL 5D-5L (EQ-5D-5L) and Kansas City Cardiomyopathy Questionnaire and patient interview and observation.ResultsA total of 20 patients with HFrEF participated in the study. The patients’ mean (SD) age was 72.5 (11.4) years, 65% were male and were classified inNYHA functional classes I (n=4), II (n=7) and III (n=9). The study showed a strong impact of HF in the patients’ quality of life (QoL) and disease experience, as revealed by the standardised PROMs (EQ-5D-5L global index=0.64 (0.36); Kansas City Cardiomyopathy Questionnaire total symptom score=71.56 (20.55)) and the in-depth interviews. Patients and caregivers often disagreed describing and evaluating perceived QoL, as patients downplayed their limitations and caregivers overemphasised the poor QoL of the patients. Patients related current QoL to distant life experiences or to critical moments in their disease, such as hospitalisations. Anxiety over the disease progression is apparent in both patients and caregivers, suggesting that caregiver-specific tools should be developed.ConclusionsPROMs are an effective way of assessing symptoms over the most recent time period. However, especially in chronic diseases such as HFrEF, PROM scores could be complemented with additional tools to gain a better understanding of the patient’s status. New PROMs designed to evaluate and compare specific points in the life of the patient could be clinically more useful to assess changes in health status.

Secondary mitral regurgitation (sMR) is characterized by left ventricular (LV) dilatation or dysfunction, resulting in failure of mitral leaflet coaptation. sMR complicates up to 35% of ischaemic cardiomyopathies (1) and 57% of dilated cardiomyopathies (2). Due to the prevalence of coronary artery disease worldwide, ischaemic cardiomyopathy is the most frequently encountered cause of sMR in clinical practice. Although mortality from cardiovascular disease has gradually fallen in Western countries, severe sMR remains an independent predictor of mortality (3) and hospitalization for heart failure (4). The presence of even mild sMR following acute MI reduces long-term survival free of major adverse events (1). Such adverse outcomes worsen as the severity of sMR increases, due to a cycle in which LV remodeling begets sMR and vice versa. Current guidelines do not recommend invasive treatment of the sMR alone as a first-line approach, due to the paucity of evidence supporting improvement in clinical outcomes. Furthermore, a lack of international consensus on the thresholds that define severe sMR has resulted in confusion amongst clinicians determining whether intervention is warranted (5, 6). The recent Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) trial (7) assessing the effectiveness of transcatheter mitral valve repair is the first study to demonstrate mortality benefit from correction of sMR and has reignited interest in identifying patients who would benefit from mitral valve intervention. Multimodality imaging, including echocardiography and cardiovascular magnetic resonance (CMR), plays a key role in helping to diagnose, quantify, monitor, and risk stratify patients for surgical and transcatheter mitral valve interventions.
