Functional Significance in Spontaneous Recanalization of a Coronary Thrombus.

Spontaneous recanalization of a coronary thrombus is an uncommon finding that may be confounded without intravascular imaging. There is little evidence regarding the functional impact of these lesions, which may be relevant to proper management. We present two cases of recanalized thrombus in which functional testing guided appropriate management.

Pulmonary arterial hypertension associated with neurofibromatosis type 1.

The authors report a case of severe pulmonary arterial hypertension (PAH) in a 75-year-old woman who had received a diagnosis of neurofibromatosis type 1 (NF1) 23 years before. She presented with progressive dyspnoea and recurrent syncope. Even though the patient initially improved after starting supportive and specific treatment for PAH, she then deteriorated and died from respiratory failure 11 months after the diagnosis of PAH.
