ABSTRACT
Flash pulmonary oedema can occur as a result of multiple triggers that may act independently or in concert. One such precipitating factor is bilateral renal artery stenosis which can be treated either with revascularisation or with medical therapy. Unilateral renal artery stenosis, however, is a rare cause of flash pulmonary oedema, especially when the contralateral kidney is still functional. We describe a case of an elderly woman with a history of heart failure with preserved ejection fraction and multiple hospitalisations for hypertensive crisis and flash pulmonary oedema who was found to have right, ostial renal artery stenosis that was treated with stent placement.

Pulse-cancellation imaging is a novel echocardiographic imaging modality developed for detection of myocardial fibrosis. This technique cancels echocardiographic reflections from the normal myocardium but clearly displays the abnormal tissue. We describe, for the first time, pulse-cancellation echocardiography application in detecting Fabry disease myocardial involvement. We present the case where both pulse-cancellation imaging and cardiac MRI concurrently revealed myocardial deposits in a patient with genotypically confirmed Fabry disease.

AIMS: Giant cell myocarditis (GCM) carries a poor prognosis and many patients require end-stage therapies. This study sought to determine the outcome of patients bridged with ventricular assist devices (VAD) to orthotopic heart transplantation (OHT). METHODS AND RESULTS: A retrospective data collection of all patients with GCM was performed. Diagnosis was determined by endomyocardial or explanted heart biopsy. Eight patients were found, but two of those patients went directly to OHT and were excluded. The remaining six patients received VADs, and these patients, aged 44 ± 18 years, were included. Five of the six patients were bridged with biventricular support and one patient was supported by left ventricular assist device (LVAD) alone. Two patients died on device support. Four patients were bridged to OHT 77 ± 42 days after device implantation. All four patients bridged with a VAD are alive, with a mean follow-up of 5.7 ± 4.1 years. Two patients were found to have recurrent GCM in the transplanted heart and were treated successfully with immunosuppression. Three patients had high grade (2R) rejection at 66 ± 52 days post-OHT. Cardiac function was preserved in all patients, and only one patient had cardiac allograft vasculopathy. CONCLUSION: Patients with end-stage GCM can be successfully bridged with VADs to OHT with very good post-OHT survival. The proper immunosuppressive regimen for this group needs further investigation given the frequency of rejection and GCM recurrence.
