Further experience with catheter closure of patent ductus arteriosus using the new Amplatzer duct occluder in children.

The aim of the present study was to report our additional experience with transcatheter closure of the patent ductus arteriosus in 65 consecutive patients using the new Amplatzer duct occluder. The median patient age was 3.6 years (range 0.

Duration of treadmill exercise testing combined with QRS score predicts adverse cardiac outcome at long-term follow-up.

Objective: Total exercise duration and abnormal QRS score values are treadmill exercise testing (TET) prognostic parameters that have been shown to be significantly and independently associated with cardiac mortality. We evaluated the prognostic value of a new index (M score, Michaelides score) incorporating TET duration and QRS score values in a simple index.

Methods: In this study, we included 626 patients, who underwent TET and coronary arteriography.

Transcatheter closure of the patent ductus arteriosus using the new Amplatzer duct occluder: initial clinical applications in children.

Background: In spite of recent advances in transcatheter management, the occlusion of certain anatomic types of patent ductus arteriosus (PDA), especially in infants and small children, remains a challenge. The aim of the study was to report initial human experience with transcatheter closure of PDA in 25 patients using the new Amplatzer duct occluder (ADO II) (AGA Medical, Golden Valley, MN).

Methods: The median age of the patients was 3.

Fungal ascending aortic aneurysm after cardiac surgery.

A 52-year-old diabetic male was admitted due to 1-month history of fever, fatigue, and mild shortness of breath. Three months prior to admission, he had undergone aortic valve replacement, with a prosthetic one, because of streptococcus viridans endocarditis complicated by severe aortic regurgitation. Transesophageal echocardiogram revealed prosthetic valve endocarditis with dehiscence of the aortic valve and an abscess cavity extending from the aortic root into the ascending aorta.

Comparison and results of transcatheter closure of patent ductus arteriosus using the swivel-disk device versus plug occluder in children.

The transcatheter closure of certain types of patent ductus arteriosus (PDA) remains a challenge. The investigators report initial clinical experience with 25 patients who underwent PDA occlusion with the use of a swivel-disk device (SDD) or a plug occluder (PO). The patients were divided into 2 groups: in the SDD group, 12 patients aged 1 to 2 years with type A PDA underwent attempted closure using the SDD, a modified Amplatzer duct occluder with a very low profile retention disk that can adapt itself at different PDA insertion angles.

Severe hemolysis complicating transcatheter occlusion of a patent ductus arteriosus: the importance of elimination of residual flow.

Transcatheter closure of a patent ductus arteriosus (PDA) is an established technique that may rarely be complicated by severe intravascular hemolysis due to residual shunt. Although conservative management has been reported, the usual approach is to invasively eliminate the residual shunt. We report a case where misjudgment of PDA size and subsequent attempted closure with only one coil led to incomplete closure and residual shunt, which was complicated by severe intramuscular hemolysis.
