Parachute mitral valve

Jagdish C Mohan, Madhu Shukla, Vishwas Mohan, Arvind Sethi
Parachute mitral valve and Pacman heart (incomplete muscular ventricular septal defect) are rare congenital deformities usually reported in infants and children. Very few adult patients with these anomalies are reported but the association of the two has not been described. This report describes a 56-year-old male with exertional dyspnea who was detected to have moderately severe mitral regurgitation and mitral stenosis. Typical parachute deformity of the mitral valve with a reduced opening and common attachment of all the chordae to a single posteromedial papillary muscle was evident...

Intervention planning is essential for successful Mitral Valve (MV) repair procedures. Finite-element models (FEM) of the MV could be used to achieve this goal, but the translation to the clinical domain is challenging. Many input parameters for the FEM models, such as tissue properties, are not known. In addition, only simplified MV geometry models can be extracted from non-invasive modalities such as echocardiography imaging, lacking major anatomical details such as the complex chordae topology. A traditional approach for FEM computation is to use a simplified model (also known as parachute model) of the chordae topology, which connects the papillary muscle tips to the free-edges and select basal points...

Shone's anomaly is a very rare congenital cardiac malformation characterized by four serial obstructive lesions of the left side of the heart (i) Supravalvular mitral membrane (ii) parachute mitral valve (iii) muscular or membranous subaortic stenosis and (iv) coarctation of aorta. We report a unique presentation of Shone's complex in a 14-year-old adolescent male. In addition to the four characteristic lesions the patient had bicuspid aortic valve, aneurysm of sinus of valsalva, patent ductus arteriosus, ventricular septal defect, persistent left superior vena cava opening into coronary sinus and severe pulmonary artery hypertension...

A 29-year old female patient was referred to our hospital for evaluation of dyspnea NYHA class I which begun from several months ago. The only abnormal sign found on physical examination was a grade 2/6 systolic murmur at the apex position without radiation. Echocardiography revealed normal left and right ventricular sizes and systolic function, and only one papillary muscle in left ventricular (LV) cavity which all chordae tendineae inserted into that muscle. The mitral valve orifice was eccentrically located at the lateral side with mild to moderate mitral regurgitation but without significant mitral stenosis...

OBJECTIVES: The aim of current study is to assess the near term impact of percutaneous ventricular restoration therapy (PVR), Parachute(®) on mitral valve (MV) geometry by cardiac computed tomography (CCT). BACKGROUND: Recent data demonstrates the feasibility of PVR for treatment of post anterior myocardial infarction (MI) heart failure. Little is known, however, about the interaction of the device and left ventricular structures, particularly the MV apparatus...

Congenital mitral stenosis (MS) is a rare congenital cardiac malformation and the obstruction to the flow across the mitral valve can be caused by supramitral ring, commissural fusion, short chordae, anomalous mitral arcade, anomalous position of the papillary muscles and the so-called'parachute mitral valve'. We describe here the case of a 47 year old male diagnosed to have a double outlet right ventricle (DORV), subaortic ventricular septal defect (VSD) with no pulmonary stenosis, severe pulmonary hypertension and congenital MS due to parachute mitral valve...

Parachute mitral valve (PMV) is a rare congenital anomaly of the mitral valve apparatus usually evidenced in infants and young children. Adult presentation is extremely rare and is generally mild in terms of mitral stenosis. A 73-year-old woman was admitted to the emergency department due to progressive dyspnea, with NYHA functional class IV symptoms on presentation. The echocardiographic examination identified a PMV with moderate mitral stenosis and a secondary smaller subvalvular mitral orifice. The report shows the usefulness of three-dimensional transesophageal echocardiography in the detection and quantification of this rare anomaly...

Congenital mitral valve (MV) malformations are uncommon, except for MV prolapse. Despite their infrequency, most of them are well-known and defined entities, such as congenital MV stenosis with two papillary muscles, parachute MV, supravalvular mitral ring, hypoplastic MV, isolated cleft in the anterior and/or posterior leaflets, and double-orifice MV. A trileaflet MV with three separate papillary muscles with concordant atrioventricular and ventricle-arterial connections is exceptionally rare. To the best of the authors' knowledge, it has been reported only once in association with subaortic valvular stenosis...

A 31-year-old asymptomatic male was referred to hospital for an examination of right bundle brunch block. Both, transthoracic and transesophageal echocardiography revealed normal left ventricular function, and two different-sized papillary muscles; the anterolateral muscle was more pronounced, with almost major chordae tendineae inserted into this dominant muscle, whereas the immature, flat posteromedial papillary muscle had very short chordae tendineae and was located higher in the left ventricle, inserted directly into the mitral annulus...

Parachute mitral valves (PMVs) and parachute-like asymmetric mitral valves (PLAMVs) are associated with congenital anomalies of the papillary muscles. Current imaging modalities cannot provide detailed biomechanical information. This study describes computational evaluation techniques based on three-dimensional (3D) echocardiographic data to determine the biomechanical and physiologic characteristics of PMVs and PLAMVs. The closing and opening mechanics of a normal mitral valve (MV), two types of PLAMV with different degrees of asymmetry, and a true PMV were investigated...

Shone's anomaly is a rare congenital cardiac malformation consisting of four obstructive lesions of the left heart and the aortic arch: a supramitral membrane; parachute mitral valve; subaortic stenosis; and coarctation of the aorta which occurs most commonly in its incomplete form. We report on a 17-year-old male Cameroonian with a variant of shone anomaly consisting of sub-valvular aortic stenosis, coarctation of the aorta and parachute mitral valve. He was referred for the investigation of a cardiac murmur after he presented with shortness of breath preceded by flu like syndrome...

BACKGROUND: The management of the zone of apposition (ZOA) in patients with atrioventricular septal defect (AVSD) and parachute left atrioventricular valve (LAVV) is controversial. METHODS: Between 1977 and 2010, 28 patients with parachute LAVV associated with AVSD were reviewed. The median age at operation was 10 months (range, 36 days to 14 years). Sixteen (57%) patients had complete AVSD and 12 (43%) had partial AVSD. Thirteen (46%) patients had moderate to severe LAVV regurgitation...

Parachute mitral valve complex is an unusual congenital anomaly that has been described by Shone et al. It is characterized by a parachute deformity of the mitral valve associated with additional forms of left heart anomalies, such as aortic valvular stenosis and coarctation of the aorta. A 21-year-old female who was referred to our department because of progressive dyspnea on effort and at rest and minimal cyanosis is presented in this case report. On cardiac auscultation, the patient had a grade III/VI pansystolic murmur best heard at the lower left sternal border...

Shone complex is a rare combination of valvular or supravalvular aortic stenosis, supra-valvular mitral membrane, parachute mitral valve, and coarctation of the aorta. This article presents an unusual case of a 40-year-old woman who presented with a history of progressive dyspnea. We describe the main imaging features and protocol used for visualizing this syndrome using various imaging modalities.

BACKGROUND: The degree of involvement of left ventricular inflow tract obstruction is the predominant factor determining outcome in Shone's anomaly. In this series of patients with Shone's anomaly, we evaluated the impact of mitral valve (MV) repair strategies performed to correct the components of this anomaly on growth of the valve and long-term functional outcome in children. METHODS: In the last 25 years, 45 children, mean age 5.16 ± 5.0 years (median, 3.9; range, 2 months-16...
