Introduction. Coupled with the increasing use of indwelling vascular catheters and prosthetic cardiac valves is an uptrend in sepsis secondary to fungemia. An insidious onset often shrouds the initial diagnosis, contributing to poor outcomes. Candida infective endocarditis (CIE) is a feared complication of candidemia, associated with high mortality rates. It requires prolonged hospital stays for medical and, often, surgical management. We report a case of a massive intracardiac Candida mass in an adult with native valve CIE. Case. A 51-year-old male on chronic total parenteral nutrition (TPN) because of bowel resection presented with fevers, night sweats, and unintentional weight loss. He was febrile and tachycardiac on admission, with a benign physical examination. Laboratory workup showed elevated inflammatory markers and an acute kidney injury. Extended blood cultures showed growth of Candida glabrata (C. glabrata) and Candida dubliniensis (C. dubliniensis). Transthoracic (TTE) and transesophageal echocardiography revealed a large mobile right atrial mass (4 cm × 6 cm × 2.5 cm), extending to the right ventricular outflow tract. Since he was a poor surgical candidate, management with micafungin was initiated and continued for 8 weeks. He responded well to the regimen with resolution of the fungal mass on follow-up TTE 3 months later. In anticipation of the future need for TPN, he continues on lifelong suppressive oral fluconazole. Conclusion. CIE may be an insidious complication of indwelling central venous catheters, necessitating a high index of suspicion. Conservative management, with antifungal therapy, can yield favorable outcomes in poor surgical candidates.
Introduction. Cardiovascular implantable electronic devices (CIEDs) are being increasingly used in the primary and secondary prevention of malignant ventricular arrhythmias and conduction system disorders. Infectious complications associated with CIEDs include infective endocarditis, lead infections, and pocket-site infections, primarily involving Staphylococcus species. Infective endocarditis is a rare but life-threatening complication of gonococcal bacteremia. We report the first case of a CIED pocket-site infection secondary to Neisseria gonorrhoeae (N. gonorrhoeae). Case. A 56-year-old male with a history of congestive heart failure status postimplantable cardioverter-defibrillator (ICD) insertion presented with a pocket-site swelling initially concerning for a hematoma which began to exhibit erythema and tenderness. The patient reported a history of high-risk sexual behavior. On presentation, he was afebrile and hemodynamically stable. Physical exam showed a 5 cm × 6 cm pocket-site swelling with overlying erythema. Labs revealed elevated ESR and CRP levels. Transthoracic and transesophageal echocardiography was concerning for infective endocarditis and lead vegetations. Blood cultures tested positive for N. gonorrhoeae. He underwent surgical debridement with complete ICD extraction and drainage of infected serosanguineous pocket fluid. Tissue cultures were negative, but isolation of N. gonorrhoeae in blood cultures confirmed it as the causative agent of the pocket-site infection in the absence of prior Gram-positive coverage. He was started on a prolonged course of ceftriaxone for 4 weeks with reimplantation of ICD at a different site after completion of treatment. Conclusion. In patients with high-risk sexual behavior, gonococcal bacteremia can potentially lead to CIED infection. These individuals should be prudently evaluated for infective endocarditis or pocket-site infections as presenting complaints can be subtle.
Introduction
To evaluate the safety of uninterrupted versus interrupted direct oral anticoagulation (DOAC) for patients undergoing catheter ablation (CA) of atrial fibrillation (AF).
Methods
We conducted a systematic search of MEDLINE and EMBASE for randomized controlled trials (RCT) and observational studies comparing uninterrupted versus interrupted DOAC for patients undergoing CA of AF. Primary outcome was major bleeding. Secondary outcomes included minor bleeding, stroke or transient ischemic attack (TIA) or thromboembolism (TE), silent cerebral ischemic events, and cardiac tamponade. Meta‐analysis was stratified by study design. Risk ratios (RR) with 95% confidence intervals were calculated using random effects model and Mantel–Haenszel method was used to pool RR.
Results
A total of 13 studies (7 randomized, 6 observational) comprising 3595 patients were included. The RCT restricted analysis did not show any difference in terms of major bleeding (risk ratio [RR] = 0.79; [0.35–1.79]), minor bleeding (RR = 0.99 [0.68–1.43]), stroke or TIA or TE (RR = 0.80 [0.19–3.32]), silent cerebral ischemic events (RR = 0.64 [0.32–1.28]), and cardiac tamponade (RR = 0.61 [0.20–1.92]). Observational study restricted analysis showed a protective effect of uninterrupted DOAC on silent cerebral ischemic events (RR = 0.45 [0.31–0.67]) and no difference in other outcomes.
Conclusions
There is no difference in bleeding and thromboembolic outcomes with uninterrupted versus interrupted DOAC for CA of AF and observational data suggests that uninterrupted DOACs are protective against silent cerebral ischemic lesions.
