Surgical closure of congenital or post-myocardial infarction (MI) muscular ventricular septal defect (MVSD) is associated with significant mortality and morbidity; therefore, both surgeons and cardiologists would welcome a safe non-surgical approach. The aim of this study is to report the combined experience of 2 cardiac centers in the transcatheter occlusion of both congenital and acquired MVSDs using the Amplatzer MVSD occluder device (AGA Medical Corporation, Golden Valley, Minnesota). Thirty-two patients underwent attempted transcatheter closure of an MVSD. Nineteen of these patients had congenital unoperated MVSD, twelve had post-MI MVSD and 1 patient had an acquired VSD post-surgical repair of hypertrophic cardiomyopathy. The median age of patients was 11.5 years (range, 0.1 86.0 years) and median weight was 34.5 kg (3.4 123.0 kg). All patients had significant shunt documented by echocardiography with a median Qp/Qs ratio of 1.7 (range, 1.0 5.3). The VSD location was mid-muscular in 14 patients, posterior in 10, apical in 5 and anterior in 3. The systolic pulmonary artery pressure ranged from 10 85 mmHg (median, 34.5 mmHg). The device was implanted successfully in 30 patients. The device size ranged from 6 26 mm (2 of these were ASD devices). There was immediate complete closure of the defect in 15 patients and 14 patients had residual shunt (foaming through the device). The median fluoroscopy time was 56.7 minutes (range, 11.7 146.0 minutes). Complications included: tamponade in 1 patient resulting in death; device malposition in 1 patient requiring surgical removal; severe hemolysis in 2 patients; and transient junctional rhythm in 1 patient. Among the 30 patients with successful implantation, three died in the hospital and 2 died later. On follow-up evaluation, there were no episodes of endocarditis, thromboembolism, hemolysis or wire disruption. We conclude that the Amplatzer MVSD occluder is a safe and effective device for closure of MVSDs up to 14 mm in diameter. Further clinical trials with this device are underway.

Aneurysms of sinuses of Valsalva (ASOV) are thin-walled saccular or tubular outpouchings of the aortic sinuses, which can be either congenital or acquired. They can rupture into heart chambers, the pulmonary artery, or the pericardial space (Perloff, Clinical recognition of congenital heart disease, [8]). This report presents a rare case of a patient with treated infective endocarditis who had a patent ductus arteriosus (PDA), a coronary cameral fistula, and a ruptured ASOV (RASOV) into the left ventricle (LV). Successful transcatheter closure of the ruptured ASOV and the other two lesions was performed using three Amplatzer duct occluders (AGA Medical Corporation, Golden Valley, MN, USA).

A 67-year-old man presented to our hospital with massive mitral and aortic valve prosthetic endocarditis 2 months after transcatheter percutaneous closure of a mitral paravalvular leak with an Amplatzer duct occluder device (AGA Medical Corp, Plymouth MN). He underwent successful reoperation for valve prosthesis replacement and reconstruction of the anterior fibrous trigone. Although transcatheter treatment of periprosthetic valve defects has been shown to be feasible, follow-up data are still limited. This procedure should be reserved only for patients who are not eligible for open surgical procedures and those with small periprosthetic defects.

A large mitral paravalvular leak in a 63-year-old patient was closed by percutaneous placement of 2 Amplatzer Septal Occluder (AGA Medical Corporation, Plymouth, MN) devices. The patient had a residual paravalvular leak and subsequently developed infective endocarditis that was successfully treated by removal of all hardware and implantation of a new valve. Transcatheter treatment of paravalvular leaks may be useful in select patients who are poor candidates for open surgery; however, one must be aware of the potential complications. This report underscores the risk of device infection that may be increased if there is turbulence related to residual paravalvular leaks.

Based on previous findings for the role of single nucleotide polymorphisms (SNPs) of TNF for the predisposition for bloodstream infections, this study investigates the role of these SNPs at the promoter positions -376, -308, -238 in infective endocarditis (IE). In a case-control study, 83 patients with IE and 83 controls were enrolled. Blood genotyping for the presence of G or A alleles of the three SNPs was carried out using restriction fragment length polymorphisms. Haplotypes were calculated. Patients were mostly infected by Staphylococcus aureus (32.5%) and by species of enterococci (14.3%) and streptococci (14.3%). Carriage of the minor frequency A alleles at -238 of the promoter region of TNF was greater than in controls (8.4% versus 1.2%, p 0.003). The presence of any of the three GGA/GAA/AGA haplotypes was more frequent in patients with IE (OR 8.22, 95CI% 1.8-37.4, p 0.001). After multivariate logistic regression analysis, it was found that the only factor related to fatal outcome was carriage of the wild-type GGG haplotype (OR, 3.29, 95CI%, 1.05-10.29, p 0.04). GGA, AGA and GAA haplotypes were more frequent in patients with IE than in controls, suggesting a predisposition for IE and a potential protective role against fatal outcome, as the wild-type GGG haplotype was independently related with death.
