Left ventricular outflow tract obstruction (LVOTO) can be caused by multiple factors. One of rare causes of LVOTO is preserved anterior mitral valve leaflet and chordal apparatus after mitral valve replacement. Here, we describe a case of a patient who presented with worsening chronic congestive heart failure secondary to LVOTO from systolic anterior motion of residual native anterior mitral leaflet. This was surgically corrected by excision of anterior leaflet and chordal apparatus through the aortic root.

This study proposes a physiologic assessment of left ventricular outflow tract obstruction (LVOTO) that accommodates changes in systolic flow and accounts for the dynamic neo-left ventricular outflow ...
The optimal method for reconstruction of the right ventricular outflow tract in tetralogy of Fallot repair is yet to be established. Transatrial repair with pulmonary valve preservation avoids the det...
Transatrial cannulation of the left ventricle was introduced as a safe and easy cannulation method for antegrade arterial return in type A aortic dissection. However, because of the paucity of clinica...
Preventative polytetrafluoroethylene coverings are often used to protect the left ventricular assist device outflow graft during sternal re-entry. We herein describe 5 cases of late-onset, significant...
Transcatheter mitral valve replacement (TMVR) is an option to treat mitral valve failure when no surgical options exist. In as many as half of patients, TMVR can cause life-threatening blo...
Left ventricular obstruction is an invalidating complication of hypertrophic cardiomyopathies (HCM), and endothelial dysfunction has also been observed in these pathologies. However, the r...
Hypertrophic cardiomyopathy (HCM) is the most common hereditary disease characterized by left ventricular hypertrophy and consequently left ventricular diastolic function. Its prevalence i...
Investigate the value of unipolar and bipolar electrograms (EGM) for predicting the successful ablation site for idiopathic outflow tract ventricular arrhythmia (OTVA).
The study evaluates the use of half-normal saline as an irrigant for open-irrigated catheters during left ventricular outflow tract ventricular arrhythmias ablation. By increasing the effi...
Occlusion of the outflow tract in either the LEFT VENTRICLE or the RIGHT VENTRICLE of the heart. This may result from CONGENITAL HEART DEFECTS, predisposing heart diseases, complications of surgery, or HEART NEOPLASMS.
A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION; (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).
Rare congenital cardiomyopathies characterized by the lack of left ventricular myocardium compaction. The noncompaction results in numerous prominent trabeculations and a loose myocardial meshwork (spongy myocardium) in the LEFT VENTRICLE. Heterogeneous clinical features include diminished systolic function sometimes associated with left ventricular dilation, that presents either neonatally or progressively. Often, the RIGHT VENTRICLE is also affected. CONGESTIVE HEART FAILURE; PULMONARY EMBOLISM; and ventricular ARRHYTHMIA are commonly seen.
Absence of the orifice between the RIGHT ATRIUM and RIGHT VENTRICLE, with the presence of an atrial defect through which all the systemic venous return reaches the left heart. As a result, there is left ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR) because the right ventricle is absent or not functional.
A condition in which the LEFT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE; MYOCARDIAL INFARCTION; and other cardiovascular complications. Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the left ventricular wall.
