Congestive hepatopathy is a symptom of right-sided heart failure; significantly lowering quality of life and increasing hospital admissions.

Mitraclip has emerged as a treatment option in high surgical risk patients with severe mitral regurgitation and its associated symptoms such as dyspnea and fatigue. It is mainly indicated in degenerative valve disease, but functional regurgitation treatment is currently being evaluated in randomized trials.

We report a case of highly symptomatic congestive hepatopathy treated with severe mitral regurgitation reduction after Mitraclip implantation.

Mitraclip is currently used in symptomatic heart failure patients with severe mitral valve regurgitation unable to undergo surgical treatment [1]. Mitral valve regurgitation is an important cause of morbidity in heart failure due to its symptoms and patients perceive them differently [2]. Although dyspnea and fatigue are the most commonly reported, right heart failure complaints such as those related to liver congestion are not negligible [3,4] and therefore are also important to consider if our aim is to improve patient’s overall well being.

Functional mitral regurgitation is common in dilated cardiomyopathy and up to 50% of symptomatic heart failure patients with severe regurgitation are not treated due to the high risk surgical procedure [5]. The role of Mitraclip in this type of disorder has been evaluated on the following observational studies: EVEREST II, TRAMI, ACCESS-EU, MARS, European Sentinel, MitraSwiss, French multicentre registries, Treede et al., Bozdag-Turan et al., Rudolph et al., Braun et al., Neus et al., with improved clinical outcomes [6-17].

We report a case of a patient with ischemic dilated cardiomyopathy with biventricular dysfunction whose main symptoms were related to congestive hepatopathy unresponsive to pharmacological treatment. We were able to successfully manage this issue with Mitraclip implantation.

Case Presentation

A 65-year-old man with a past medical history of hypertension, stage three chronic kidney disease, permanent atrial fibrillation and ischemic dilated cardiomyopathy with New York Heart Association (NYHA) class 2 heart failure was hospitalized due to one-month history of worsening of bilateral leg edema, abdominal right upper quadrant discomfort with nausea (especially after meals), subsequent weight loss (11 pounds) and anorexia. He also reported dyspnea on mild exertion with no fatigue, but according to the patient those were not considered important complaints with limitation in daily life activities. He denied other gastrointestinal symptoms, fever, night sweats, cough, palpitations, chest and low back pain or even genitourinary symptoms.

On general examination, he had a body mass index of 18 kg/ m² and at rest he did not have dyspnea. He was anicteric, wellhydrated and demonstrated right internal jugular vein distention. Cardiopulmonary auscultation revealed a grade 5 systolic murmur at the apical area with axillary irradiation and discrete bilateral lung rales. Abdominal examination elicited pain during superficial palpation on the right upper quadrant with hepatomegaly identification, with no signs of ascites. He had significant symmetrical peripheral pitting edema without any signs of deep vein thrombosis. His vital signs were normal, including fever absence. There were no additional examination abnormalities.

Abdominal ultrasound showed signs of congestive hepatomegaly with a dilated inferior vena cava (Figure 1) and a diffuse gallbladder wall thickening with small ascites, without additional complications. Laboratory studies only showed a mild cytocholestatic pattern (alkaline phosphatase 167 IU/L; aminotransferase 76 IU/L; alaninetransferase 80 IU/L; total bilirrubin 2.0 mg/dL). Chest x-ray did not show additional changes besides those previously known such as cardiomegaly. Electrocardiogram showed atrial fibrillation with a normal heart rate. Brain natriuretic peptide was 690 ng/L.
