Parachute mitral valve (PMV) is a congenital cardiac malformation where typically all tendons chordae converge and insert into one major papillary muscle. We report the case of 27-year-old man affected by Hodgkin’s lymphoma-mixed cellularity subtype with polychemotherapy treatment and Barrett’s esophagus who came to our attention for routine echocardiographic exam and evaluation of left ventricular function. In the presence of normal left ventricular systolic function and mild-moderate mitral regurgitation, a careful examination of mitral apparatus showed a single papillary muscle suspected for PMV. In the presence of Barrett’s esophagus, the patient was further assessed cardiac magnetic resonance (CMR) that confirmed the diagnosis of PMV and excluded other associated congenital anomalies. Despite the rare incidence of PMV and a diagnosis generally based on transesophageal echocardiography, CMR could represent a useful tool, in selected cases, to confirm the diagnosis of PMV, identify other possible congenital anomalies, and assess ventricular and valvular function.
Papillary fibroelastoma is a rare benign cardiac tumor, second after cardiac myxoma as more frequent cardiac valvular tumor. The therapy is usually based on surgery according to size, mobility, symptoms, and risks of surgery. We report the case of a 67-year old female with transient ischemic attack. Echocardiography showed the presence of a round mobile formation localized on the atrial side of septal leaflets of tricuspid valve, first identified as an endocarditis vegetation. Cardiac magnetic resonance (cMRI) confirmed the presence of the mass and showed an isointense signal in T1-turbo spin echo sequences, hypointense in cine steady-state free precession and in first-pass sequences, and hyperintense in T2 and phase-sensitive inversion recovery with central hypointense core, with a suspected diagnosis of fibroelastoma. The patient underwent cardiac surgery and histology confirmed the presence of fibroelastic tissue with papillary extroflexions compatible with diagnosis of fibroelastoma. The use of cMRI may be useful in the evaluation of the exact position, dimensions, and nature of cardiac masses and fibroelastomas, diagnostic workup, and preliminary assessment before surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
