[Acute aortic dissection in a patient with advanced coronary artery disease--a case report].

A case of a 58-year-old male with acute aortic dissection is presented. A few months earlier the patient underwent transmyocardial laser revascularisation and implantation of venous graft to the left anterior descending coronary artery due to three-vessel disease. Acute aortic dissection was successfully treated by surgery.

Changes in cardiac adrenergic nervous system after transmyocardial laser revascularisation assessed by I-123-MIBG SPECT. A preliminary report.

Background: Metaiodobenzylguanidine (MIBG), a noradrenaline analogue which may be labelled with I-123, has been used in the assessment of pre-synaptic activity of the cardiac adrenergic nervous system (Syst(adren)) in several diseases. The effects of transmyocardial laser revascularisation (TMLR) on Syst(adren) have not yet been established.

Aim: To examine whether TMLR-induced changes in Syst(adren) may be one of the mechanisms responsible for clinical improvement in patients undergoing this method of revascularisation.
