Case ReportsLong-term event-free survival with an embolised prosthetic valve leaflet in the thoracic aorta.
We report the case of a patient who underwent a redo surgery for a leaflet escape from a Bjork-Shiley tilting disc mitral prosthesis inserted 18 years previously. The escaped disc remained lodged in the thoracic aorta without any complication. ⋯ We believe this to be the longest survival with a dislodged leaflet from a mechanical valve. Removal of dislodged disc is recommended in literature but there may be a place for watchful observation in exceptional cases with no haemodynamic compromise.

Case ReportsAberrant right subclavian artery and calcified aneurysm of Kommerell's diverticulum: an alternative approach.
We report a 72 year-old man with dysphagia and dizziness. Aortography and Computed tomographic scans revealed the aberrant right subclavian artery arising from a calcified aneurysm of the Kommerell's diverticulum and bilateral carotid artery disease with atherosclerotic narrowing. Surgical relief was accomplished by excluding the aneurysm from circulation through the aortic arch and a 10 mm graft was interposed between the aberrant artery and the ascending aorta.

Comparative StudyClinical implications of granulomatous inflammation detected by endobronchial ultrasound transbronchial needle aspiration in patients with suspected cancer recurrence in the mediastinum.
Granulomatous inflammation has been previously reported in association with cancer. Endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) is a new minimally invasive test for investigating mediastinal lymphadenopathy. The identification of granulomatous inflammation by EBUS-TBNA and the clinical implications of such detection in a series of patients with previously treated cancer and new mediastinal lymphadenopathy has not previously been performed. ⋯ In an academic cancer institute, at least 5% of patients undergoing EBUS-TBNA have sarcoid-like lymphadenopathy mimicking cancer recurrence. Further studies to define the precise etiology, natural history and prognosis of this phenomenon are warranted.

Case ReportsTransvenous right ventricular pacing in a patient with tricuspid mechanical prosthesis.
We report a patient in whom permanent endocardial pacing was accomplished by passage of the electrode through a mechanical tricuspid valve. Echocardiography study showed a minimal tricuspid regurgitation.

Case ReportsTraumatic aortic arch false aneurysm after blunt chest trauma in a motocross rider.
This article details a case report of a traumatic aortic arch false aneurysm after blunt chest trauma. Thoracic aorta false aneurysms are a rare and life-threatening complication of aortic surgery, infection, genetic disorders and trauma.
