Parachute mitral valve

Hedieh Alimi, Afsoon Fazlinezhad
BACKGROUND: Parachute tricuspid valve is a rare congenital malformations explained in the literature. In most cases, this malformation coexists with other congenital defects. The importance of this condition depends on its functional consequences. CASE REPORT: First case was a 52-year-old female patient presented with palpitation. She had a history of paroxysmal supraventricular tachycardia. Transthoracic echocardiography revealed large secundum type atrial septal defect and all the tricuspid valve leaflets appeared to be connected to a single calcified papillary muscle in right ventricle suggestive of parachute tricuspid valve...

An accessory papillary muscle is an uncommon congenital anomaly usually found incidentally on routine cardiac imaging. While frequently asymptomatic, it is occasionally associated with mitral regurgitation, left ventricular dynamic outflow obstruction and hypertrophic cardiomyopathy1 and it is important to differentiate it from other pathological processes including papillary fibroelastoma, left ventricle thrombus, hemangioma, a single papillary muscle with a parachute mitral valve and a left ventricle false tendon...

The therapeutic implications of bicuspid aortic valve associations have come under scrutiny in the transcatheter aortic valve implantation era. We evaluate the spectrum of mitral valve disease in patients with bicuspid aortic valves to determine the need for closer echocardiographic scrutiny/follow-up of the mitral valve. A retrospective analysis of echocardiograms done at a referral hospital over five years was conducted in patients with bicuspid aortic valves with special attention to congenital abnormalities of the mitral valve...

Parachute and hammock valves in children remain one of the most challenging congenital malformations to correct. We report our institutional experience with valve-preserving repair techniques and the early and late surgical outcomes in parachute and hammock valves in infants and children. From January 1990-June 2014, 20 infants and children with parachute (n = 12, median age = 2.5 years, range: 2 months-13 years) and hammock (n = 8, median age = 7 months, range: 1 month-14.9 years) valves underwent mitral valve (MV) repair...

BACKGROUND: Shone complex consists of a constellation of left-sided, usually obstructive, cardiac lesions, including supravalvar mitral ring, parachute mitral valve, subaortic stenosis, and aortic coarctation. Incomplete Shone complex consists of a mitral valve anomaly associated with lesions involving the subaortic region, aortic valve, or thoracic aorta. There is a paucity of data regarding long-term outcomes in adults with Shone complex. METHODS: We reviewed records of adults with complete or incomplete Shone complex followed at the Montreal Heart Institute between 1982 and 2014...

BACKGROUND: Congenital anomaly wherein the mitral valve leaflets are directly attached to the papillary muscle(s) (PM) with or without short under-developed chords is rarely reported in adults. Patients with two PMs with an intervening fibrous bridge have also been included under this head in previous studies. METHODS: Echocardiography enables accurate evaluation of the morphology and function of valve leaflets, chordae tendineae, and PM. This report describes a series of six patients aged 56-84 years who had abnormal mitral valve with a large solitary and anomalously inserted PM seen over a period of 3 years...

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...

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...
