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 tract (LVOT).

The good knowledge of the characteristics of the left outflow tract allows us to detect but also to identify anomalies such as conal VSD and conotruncal anomalies. The analysis of this specific area o...
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...
Postoperative pseudoaneurysm of the left ventricular outflow tract after valve-sparing root replacement is a rare but critical complication. We present a case of postoperative left ventricular outflow...
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...
Congenital heart disease remains an important cause of perinatal morbidity and mortality. Screening for these is based on a good knowledge of normal fetal heart anatomy and ultrasound views to be perf...
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...
Pulmonary homografts are standard substitutes for right ventricular outflow tract reconstruction in congenital heart surgery. Unfortunately shortage and conduit failure secondary to early ...
Carvedilol is known to be effective in reducing ventricular arrhythmias and mortality in patients with heart failure. It is suggested that one of the mechanisms is its ability to block sto...
The purpose of this early feasibility study is to determine how a new transcatheter pulmonary valve will move and perform once implanted in the right ventricular outflow tract.
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.
