In a 4.5-year-old child with refractory pulmonary arterial hypertension, we performed atrial septostomy with the application of an Amplatzer fenestrated device designed to maintain patency. Continuous intravenous epoprostenol infusion was started concomitantly. Forty-two months after the procedure, the patient had no recurrent syncope and remained in New York Heart Association ...

A quadricuspid aortic valve (QAV) is a rare congenital heart defect, previously described as an incidental finding at the time of surgery or postmortem, which is now being increasingly detected by 2D transthoracic or transesophageal echocardiogram. With advances in echocardiography, secondary cardiac anomalies are also being described in association with ...

One year after Amplatzer device closure of an atrial septal defect, an aortic to left atrial fistula was diagnosed in a patient who developed a new onset murmur with no other symptoms. The fistula was closed with a 4-mm Amplatzer Septal Occluder during a transcatheter procedure, avoiding the need for ...

OBJECTIVES: This study evaluated the variability and time resource utilization of bedside 3-dimensional echocardiographic left ventricular volume analysis (3D-LVVA) in congenital heart disease (CHD). Background. There are currently limited data on the resource utilization and variability of 3D-LVVA in the CHD. METHODS: Four reviewers of varying experience levels were timed ...

Aortopulmonary window is a rare congenital heart defect, often requiring open surgical closure. Distal windows with good margins from the semilunar valves and coronary artery origin are amenable for transcatheter closure. Experience in nonsurgical closure of such defects is limited. We report closure of distal aortopulmonary window in 2 patients ...

Complete atrioventricular (AV) canal defects usually have right and left valve components of approximately equal size, although unbalanced forms do occur. Optimal management of unbalanced AV canal defects is controversial, with no proven guidelines for choosing between biventricular repair and univentricular palliation. We describe successful biventricular repair of a right-dominant ...

This paper presents a case of a rare combination of right lung agenesis and atrial septal defect type II (ASD II). Successful surgical repair of ASD II was performed at the age of six years with total circulatory arrest (TCA) and deep hypothermia, because of difficult approach. Computed tomography and ...

We describe a patient with severe pulmonary artery hypertension and refractory right heart failure who underwent "butterfly" stent atrial septostomy guided by intracardiac ultrasound. This technique may be superior to previously reported blade and balloon septostomy because it allows creation of an atrial septal defect of a precise predetermined diameter. ...

BACKGROUND: Transcatheter Amplatzer septal occluder (ASO) device closure of atrial septal defects (ASDs) has traditionally been guided by two-dimensional transesophageal echocardiography (2D-TEE) and intracardiac echocardiography (ICE) modalities. Real time three-dimensional transthoracic echocardiography (RT3D-TTE) provides rotating images to define ASD and adjacent structures with potential as an alternative to 2D-TEE or ...

A 29-year-old woman who had undergone closure of a secundum-type atrial septal defect using the Amplatzer device 2 years previously developed acute and progressive altered mentation. Initial clinical and imaging data confirmed the diagnosis of multiple cerebral, cerebellar and brain stem emboli, and infarcts. She was treated urgently with an ...

Percutaneous transvenous mitral commissurotomy (PTMC) is an effective treatment for mitral stenosis, but trans-septal puncture carries a certain risk of complications. There have been few reports on phase-array intra-cardiac echocardiography (ICE) guidance in trans-septal puncture for PTMC, especially in patients with dilated left atrium or distorted anatomy. Herein, we report ...

A 33-year-old man presented with an acute myocardial infarction (MI) after a recent long-haul flight. Angiography revealed thrombus in the right and circumflex coronary artery but no underlying atherosclerosis. Echocardiography revealed the presence of an atrial septal defect (ASD). In view of the recent flight, the presence of an ASD ...

Left ventricular outflow tract (LVOT) obstruction has been classically observed in hypertrophic cardiomyopathy in which the LVOT obstruction is associated with asymmetric septal hypertrophy producing a systolic pressure gradient across the LVOT. Basal septal hypertrophy (BSH) with hypertension may result in dynamic LVOT obstruction as well. It was suggested that ...

Multidetector-row computed tomography (MDCT) studies were performed in three adult patients with pulmonary atresia with a ventricular septal defect. In all patients, the native pulmonary arteries were absent, and the pulmonary circulation was totally supplied by major aortopulmonary collateral arteries (MAPCAs). MDCT studies with 1-mm collimation provided detailed information on ...

Atrial septal defect transcatheter occlusion techniques have become a reliable alternative to surgical procedures. Possible complications can derive from unfavorable anatomy of the defect and over-dimensioning of the device. We describe the first case ever reported of anterior mitral leaflet perforation caused by an atrial septal occluder. The diagnosis was ...

Myocardial progenitor cells expressing Fgf10 give rise to the outflow tract and right ventricle of the mammalian heart. In order to define the role of fibroblast growth factor (FGF) signaling in this process we investigated whether Fgf10 or the major Fgf10 receptor Fgfr2-IIIb are required for normal heart development. The ...
