Invasive aspergillosis (IA) is the most common invasive fungal infection following a hematopoietic cell transplant, with emerging cryptic species exhibiting resistance to commonly used antifungals such as azoles. These species have been increasingly found after the introduction of anti-mold prophylaxis. We report a case of a 56-year-old female with primary myelofibrosis whose allogeneic hematopoietic cell transplant was complicated by disseminated fungal infection (skin, lung) due to Aspergillus calidoustus, a cryptic specie. Treatment of Aspergillus species remains challenging as these cryptic species are usually resistant to azoles including voriconazole which is the first line of treatment of IA. Infection was successfully treated with surgical excision and combination antifungal therapy based on in vitro susceptibility and synergy testing. Therapy included isavuconazole, a drug that has been shown to be non-inferior to voriconazole in the treatment of invasive mold infections.

INTRODUCTION

Late lead perforation (LLP), defined as perforation ≥30 days from cardiac implantable electronic device implant, is a rare diagnosis and little data exist regarding management practices and outcomes. The purpose of this study was to evaluate the occurrence, safety, and efficacy of transvenous management of clinically significant LLP.

METHODS

The electronic medical records of a single-center tertiary hospital were reviewed for all patients who were referred for LLP or its sequelae.

RESULTS

Eleven consecutive patients were identified from October 2011 to December 2018 with clinically significant LLP. Patients most often presented with pericardial symptoms with the exception of one asymptomatic patient. The median time from lead implant to intervention for LLP was 246 days. Nine patients were managed with an initial transvenous approach, with one requiring sternotomy (lead 6.3 years old). Two patients had a surgical approach, one performed at an outside hospital with subsequent death and another had a mini-thoracotomy, but the lead was removed percutaneously with no surgical repair. In this small cohort, there was no association between the lead extending beyond the parietal pericardium and surgical repair (P = .99).

CONCLUSION

Our single-center experience suggests that LLP can be initially managed with a cautious transvenous approach in most patients, but intraprocedural ultrasound for pericardial monitoring and a rescue plan with immediate surgical back up is mandatory.
