INTRODUCTION: Double orifice mitrol valve (DOMV) is a very rare congenital heart defect. CASE REPORT: We reported 20-year-old male referred to our center due to evaluation of his cardiologic status. He was operated on shortly after birth for a tracheoesophageal fistula. Accidentally, echocardiography examination at the age of 4 years revealed double orifice mitral valve (DOMV) without the presence of mitral regurgitation, as well as mitral stenosis, with normal dimensions of all cardiac chambers...

A 65-year-old woman was admitted to our institution for rest dyspnea and hypotension. EKG showed sinus tachycardia with signs of infero-posterior STEMI. 2D-echocardiogram showed severe left ventricular systolic dysfunction with a- diskynesia of the inferior and posterior walls and severe functional mitral regurgitation (MR). The patient underwent urgent coronary angiography that showed 3-vessels disease with total occlusion of both first obtuse marginal (OM) branch of the left circumflex artery and right coronary artery (RCA) and critical stenosis of left anterior descending (LAD)...

To describe preliminary experience of percutaneous pulmonary valve implantation, in a single pulmonary branch position. Two procedures in 2 patients from a single center are described, where implantation of percutaneous valves within a single pulmonary artery branch was technically successful. The procedural indication was pulmonary valve regurgitation and/or residual stenosis. The 2 patients were symptomatic. An Edwards Sapien™ valve (Patient 1), and a Medtronic Melody™ valve (Patient 2) were implanted...

Absent pulmonary valve syndrome (APVS) is a rare congenital heart disease that is easily misdiagnosed as tetralogy of Fallot (TOF). We herein discuss the echocardiographic features of APVS, compare its two subtypes, and clarify some differences between APVS and TOF. From July 1998 to October 2011, 31 patients diagnosed with APVS at Fuwai Hospital underwent echocardiography, computed tomography, or cardiac angiography. APVS was clinically categorized as either infant-type or child-type. We compared the echocardiographic similarities and differences between APVS and TOF and between the two subtypes of APVS...

BACKGROUND AND OBJECTIVES: Repair of tetralogy of Fallot (TOF) with monocusp pulmonary valve reconstruction prevents pulmonary regurgitation (PR) for a variable period. Since postoperative outcome is governed by PR and right ventricular function, we sought to assess the severity of pulmonary regurgitation and right ventricular outflow (RVOT) gradient in the immediate postoperative period and at 1 year and attempted to identify the anatomical substrates responsible for adverse outcomes...

BACKGROUND: We sought to improve understanding of the diastolic prolongation of forward flow seen through a unilateral branch pulmonary artery (PA) stenosis. METHODS AND RESULTS: Of patients studied by cardiovascular magnetic resonance (CMR) for congenital heart disease, we reviewed right and left PA flow to find 10 cases with a diastolic prolongation of flow in a stenosed branch PA. They were aged 20 years (median, range = 14-40 years, 7 males). Seven had transposition of the great arteries corrected by arterial switch (TGA-AS) and 3 had repaired tetralogy of Fallot (rToF)...

Biventricular repair in right atrial isomerism is rarely feasible due to associated anomalies of venous connection, ventricular imbalance, nonroutabilty of the interventricular communication, a common atrioventricular junction, and inadequate pulmonary arterial branches. These patients are also often not ideal for univentricular repair due to some of the above associations. We describe a novel surgical technique that was utilized in such a patient for biventricular repair of a child with right atrial isomerism with total anomalous pulmonary venous connection, regurgitant common atrioventricular valve, hypoplastic left ventricle, nonroutable ventricular septal defect, and pulmonary stenosis...

In tetralogy of Fallot with absent pulmonary valve, pulmonary stenosis and regurgitation results in significant pulmonary artery dilatation. Branch pulmonary artery dilatation often compresses the tracheobronchial tree, causing fluid trapping in fetal life and air trapping and/or atelectasis after birth. Prenatal diagnosis predicts poor prognosis, which depends on the degree of respiratory insufficiency from airway compromise and lung parenchymal disease after birth. Fetal magnetic resonance imaging (MRI) has been useful in evaluating the effects of congenital lung lesions on lung development and indicating severity of pulmonary hypoplasia...

Right ventricular (RV) volume overload secondary to pulmonary regurgitation is common in patients after initial repair of tetralogy of Fallot (TOF) and is associated with adverse long-term outcomes. The objective of the present study was to determine the effect of branch pulmonary artery stenosis on the RV volume in patients with repaired TOF. We reviewed 178 cardiac magnetic resonance imaging studies in patients with repaired TOF. We defined bilateral stenosis as a Nakata index of ≤200 mm(2)/m(2) and concordant branch pulmonary artery cross-sectional area, unilateral stenosis as 1 branch pulmonary artery cross-sectional area ≤100 mm(2)/m(2) and 1 branch pulmonary artery cross-sectional area >100 mm(2)/m(2), and restrictive physiology as prograde main pulmonary artery diastolic flow...

OBJECTIVE: Chronic pulmonary regurgitation (PR) has deleterious effects on right ventricular (RV) function in repaired tetralogy of Fallot (ToF). However, there are little data regarding right ventricular outflow tract (RVOT) contractile dysfunction in response to chronic PR and on both RV and LV volumes and function. METHODS: We retrospectively identified consecutive patients with PR who were referred for magnetic resonance imaging quantification of "free PR" detected on echocardiography between 2003 and 2008...

After having undergone surgical correction at an early age, many patients with tetralogy of Fallot develop long-term complications including progressive pulmonary regurgitation and peripheral pulmonary stenosis. A high percentage of these patients need to undergo a second operation in their adolescence or early adulthood. If simultaneous treatment of both pulmonary regurgitation and peripheral pulmonary stenosis is warranted, a complete surgical approach has several disadvantages. We describe four cases of Fallot patients with severe pulmonary regurgitation and peripheral pulmonary stenosis who were treated using a hybrid approach involving surgical implantation of a pulmonary homograft and peroperative stenting of the pulmonary artery...

OBJECTIVES: We sought to investigate whether differential branch pulmonary artery (BPA) regurgitation correlates with differences in BPA anatomy and physiology. BACKGROUND: Patients with repaired conotruncal anomalies such as Tetralogy of Fallot frequently have residual BPA stenosis or BPA size differences. Previous reports have demonstrated an increased left pulmonary artery (LPA) regurgitant fraction (RF) in these patients. METHODS: We retrospectively reviewed 76 consecutive cardiac magnetic resonance (CMR) studies for BPA size and phase-contrast magnetic resonance data, including 13 consecutive patients who underwent both CMR and catheterization...

With prevalences ranging from 0.26 to 0.8‰ of all live births tetralogy of Fallot (TOF) is the most common congenital heart disease with primary cyanosis. Due to improvements in surgical techniques, nearly all patients can nowadays expect to reach adulthood. After surgical repair, pulmonary regurgitation (PR) occurs in almost every child and is an important contributing factor in long-term morbidity and mortality. Cardiac magnetic resonance imaging is well established for functional assessment and flow measurements and is an ideal tool for serial post-surgical follow-up examinations, as it is non-invasive and does not expose patients to ionizing radiation...

BACKGROUND: Transannular patch (TAP) repair of tetralogy of Fallot often results in significant right ventricular outflow tract (RVOT) dilation and distortion. We hypothesized that insertion of Melody valves into the proximal right and left branch pulmonary arteries (PAs) would reduce pulmonary regurgitation fraction (PRF) in an ovine model of pulmonary insufficiency and dilated RVOT. METHODS AND RESULTS: Ten sheep underwent baseline cardiac catheterization, surgical pulmonary valvectomy, and TAP placement...

BACKGROUND: The grading of pulmonary regurgitation (PR) severity by two-dimensional (2D) and Doppler echocardiography is not standardized. Cardiovascular magnetic resonance imaging is the clinical gold standard for PR quantification. The purpose of this study was to determine the best 2D and Doppler echocardiographic predictors of severe PR. METHODS: Thirty-six patients with tetralogy of Fallot or pulmonary valve stenosis with prior pulmonary valvuloplasty or transannular or subannular patch repair underwent 2D and Doppler echocardiography and cardiovascular magnetic resonance...

OBJECTIVES: This study was designed to report a novel indication for percutaneous pulmonary valve implantation in patients with previous right ventricular outflow tract (RVOT) patch. BACKGROUND: Current indications for percutaneous pulmonary valve implantation are limited to patients who had pulmonary valve stenosis and/or regurgitation in a right ventricle-to-pulmonary artery conduit. Percutaneous pulmonary valve implantation has not been previously reported in patients with severe pulmonary valve regurgitation following repair of tetralogy of Fallot (TOF) using RVOT patch...
