Atrial Septal Defect Closure Device-Related Infective Endocarditis in a 20-Week Pregnant Woman.

ABSTRACT: With increasing atrial septal defect (ASD) repairs, more women of childbearing age will have ASD closure devices. Current ASD closure trials have excluded women planning pregnancy, making their management challenging. We present a pregnant woman, with a repaired ASD, who presented with device-related infective endocarditis. (Level of Difficulty: Beginner.).

Angioscopic Evaluation of Atrial Septal Defect Closure Device Neo-Endothelialization.

Project description:Background Current guidelines recommend at least 6 months of antithrombotic therapy and antibiotic prophylaxis after septal-occluding device deployment in transcatheter closure of atrial septal defect. It has been estimated that it takes ≈6 months for complete neo-endothelialization; however, neo-endothelialization has not previously been assessed in vivo in humans. Methods and Results The neointimal coverage of septal occluder devices was evaluated 6 months after implantation in 15 patients by angioscopy from the right atrium. Each occluder surface was divided into 9 areas; the levels of endothelialization in each area were semiquantitatively assessed by 4-point grades. Device neo-endothelialization was sufficient in two thirds of patients, but insufficient in one third. In the comparison between patients with sufficiently endothelialized devices of average grade score ≥2 (good endothelialization group, n=10) and those with poorly endothelialized devices of average grade score <2 (poor endothelialization group, n=5), those in the poor endothelialization group had larger devices deployed (27.0 mm [25.0-31.5 mm] versus 17.0 mm [15.6-22.5 mm], respectively) and progressive right heart dilatation. The endothelialization was poorer around the central areas. Moreover, the prevalence of thrombus formation on the devices was higher in the poorly endothelialized areas than in the sufficiently endothelialized areas (Grade 0, 94.1%; Grade 1, 63.2%; Grade 2, 0%; Grade 3, 1.6%). Conclusions Neo-endothelialization on the closure devices varied 6 months after implantation. Notably, poor endothelialization and thrombus attachment were observed around the central areas and on the larger devices.

Closure of Iatrogenic Atrial Septal Defect After Placement of Left Atrial Appendage Closure Device.

Project description:An 86-year-old woman experienced hypoxia with right-to-left flow across an iatrogenic atrial septal defect after deployment of a left atrial appendage closure device. Emergent closure of the defect was performed with an atrial septal occluder device with resolution of hypoxia. (Level of Difficulty: Intermediate.).

Ventricular septal defect and bivalvular endocarditis.

Project description:A 63-year-old man presented with generalized fatigue, chills, malaise, dyspnea, intermittent fevers, and 50-pound weight loss of 4 months' duration. Blood cultures were positive for pan-sensitive Streptococcus anginosus. Transesophageal echocardiography showed an 11 mm × 3 mm mobile mass attached to the mitral valve, a 16 mm × 16 mm mobile mass attached to the pulmonary valve, and a small membranous ventricular septal defect. The patient received 12 weeks of intravenous (IV) antibiotics with eventual resolution of the masses. Multi-valve endocarditis involving both the left and right chambers is rarely reported without prior history of IV drug use or infective endocarditis. Our case emphasizes the importance of careful assessment for ventricular septal defects or extra-cardiac shunts in individuals who present with simultaneous right and left-sided endocarditis.

Biventricular infective endocarditis in an immunocompetent adult patient with a congenital ventricular septal defect: a case report.

Project description:IntroductionCongenital heart defects predispose patients to a significantly increased risk of infective endocarditis (IE), and the incidence is even greater in the immunocompromised population. The involvement of multiple valves leads to a higher rate of complications and thus mortality. Moreover, biventricular IE is an uncommon condition with no specific guidelines for treatment.Case presentationIn this report, we discuss a case of an immunocompetent young male with a congenital perimembranous ventricular septal defect, complicated by multivalvular and right ventricular free wall vegetations. Biventricular involvement of IE along with septic embolization to both the pulmonary and systemic circulation resulted in challenges in the management of this patient.DiscussionThe decision regarding timing and type (surgical vs. conservative) of treatment in such a complicated and aggressive IE case should be based on individual circumstances. However, the strategy of initial antibiotic therapy followed by surgical intervention can be a suitable option in such patients.

Percutaneous Closure of 2 Paravalvular Leaks and a Gerbode Defect after Mitral Valve Replacement for Infective Endocarditis.

Project description:Surgical valve replacement after infective endocarditis can result in local destructive paravalvular lesions. A 30-year-old woman with infective endocarditis underwent mitral valve replacement that was complicated postoperatively by 2 paravalvular leaks. During percutaneous closure of the leaks, a Gerbode defect was also found and closed. We discuss our patient's case and its relation to others in the relevant medical literature. To our knowledge, we are the first to describe the use of a percutaneous approach to close concomitant paravalvular leaks and a Gerbode defect.

A case report: Amplatzer occluder device closure of an iatrogenic ventricular septal defect following radiofrequency ablation.

Project description:BackgroundInterventricular septal perforation is an extremely rare complication of radiofrequency ablation (RFA), with an incidence of 1%. The most common mechanism is a 'steam pop', which can be described as 'mini-explosions' of gas bubbles. Data for percutaneous repair of cardiac perforations due to RFA are limited.Case summaryA 78-year-old female patient was referred to our department for the treatment of two iatrogenic ventricular septal defects (VSDs) following radiofrequency ablation (RFA) of premature ventricular contractions. One week post-ablation, chest pain and progressive dyspnoea occurred. Transthoracic echocardiography detected a VSD, diameter 10 mm. Hence, iatrogenic, RFA-related myocardial injury was considered the most likely cause of VSD, and the patient was referred to our tertiary care centre for surgical repair. Cardiovascular magnetic resonance (CMR) imaging demonstrated border-zone oedema of the VSD only and confirmed the absence of necrotic tissue boundaries, and the patient was deemed suitable for percutaneous device closure. Laevocardiography identified an additional, smaller muscular defect that cannot be explained by analysing the Carto-Map. Both defects could be successfully closed percutaneously using two Amplatzer VSD occluder devices.DiscussionIn conclusion, this case demonstrates a successful percutaneous closure of a VSD resulting from RFA using an Amplatzer septal occluder device. CMR might improve tissue characterization of the VSD borders and support the decision if to opt for interventional or surgical closure.
