Rescrewing the embolized duct occluder using the delivery cable.

We report the successful re-screwing of the embolized duct occluder (DO) in three children for retrieval and to attempt redeployment. The DO was embolized into descending aorta immediately after the deployment in one child and within 24 h after the procedure in two further patients. The DO was re-screwed back by the DO delivery cable, using "sheath in sheath" in all three cases; however, successful retrieval could be done only in two.

Transcatheter closure of large right pulmonary artery-to-left atrial fistula.

We report the successful transcatheter closure of right pulmonary artery fistula to left atrium in a six-year-old boy, who had presented with cyanosis and shortness of breath. The two-dimensional echocardiogram with bubble contrast study demonstrated the communication between right pulmonary artery and left atrium. Computerized tomography confirmed the diagnosis and delineated the anatomy.

Transcatheter trans-septal antegrade closure of muscular ventricular septal defects in young children.

Background: Surgical or transcatheter closure of muscular ventricular septal defects (mVSDs) in young children may be technically challenging and associated with significant complications.

Objective: To assess the feasibility of trans-septal antegrade closure of mVSD in a selected subset of young children.

Methods: This is a prospective study from a single centre from July 2011 to March 2013.

Unexpected difficulty during transcatheter device closure of atrial septal defect associated with right aortic arch.

Right aortic arch (RAA) associated with isolated atrial septal defect (ASD) is very rare. We report successful closure of ASD associated with RAA using a 26-mm atrial septal occluder in a 30-year-old male patient. The impingement of right descending aorta in RAA caused malposition of the device in the left atrium.

Retrograde transcatheter closure of ventricular septal defects in children using the Amplatzer Duct Occluder II.

Objectives: To describe the technique and results of transcatheter closure of ventricular septal defects (VSDs) by a modified retrograde transarterial approach using the new Amplatzer Duct Occluder II (ADO II).

Background: Transcatheter device closure of ventricular septal defects (VSDs) by antegrade method is well established, but a challenging procedure. We describe a retrograde technique that obviates the need for arteriovenous looping.

Coronary artery bypass grafting with or without cardiopulmonary bypass in patients with preoperative non-dialysis dependent renal insufficiency: a randomized study.

Objective: Preoperative renal insufficiency is a predictor of acute renal failure in patients undergoing coronary artery revascularization with cardiopulmonary bypass. Off-pump coronary artery bypass grafting has been shown to be less deleterious than on-pump bypass in patients with normal renal function, but the effect of this technique in patients with non-dialysis dependent renal insufficiency in a randomized study is unknown.

Methods: From August 2004 through October 2005, 116 consecutive patients with preoperative non-dialysis-dependent renal insufficiency (glomerular filtration rate measured using the Modification of Diet in Renal Disease equation [MDRD GFR] < or = 60 mL x min(-1) x 1.
