Abstract

Using a fast version of selective inversion recovery, we have obtained coronary angiograms of normal volunteers showing the proximal portions of the left coronary artery. Blood is tagged in the aortic root at end systole using a 2D inversion pulse. After a wash-in time of 300-600 ms, the coronary vessels are imaged with a 2- to 3-cm-thick slab in either axial or oblique projection. The scan is completed within a breathhold in 24 heartbeats.

[Stress echocardiography in 11 patients with symptoms of ischemia and a myocardial bridge: no indication of a causal connection in 10 cases].

OBJECTIVE: To determine whether in patients with a myocardial bridge, systolic compression of the affected coronary branch may cause cardiac ischaemia and is of clinical relevance. DESIGN: Pilot inventory. METHOD: In 11 consecutive patients with an established myocardial bridge who presented with possible ischaemic symptoms angiographic dobutamine stress-echocardiography was used to visualize hypokinesia caused by ischaemia in the area ofmyocardium supplied by the bridged artery. RESULTS: Hypokinesia was observed in the area supplied by the bridged artery in one of the patients (9%). The symptoms in the other patients were not associated with the bridge. CONCLUSION: The clinical relevance of myocardial bridging appeared to be smaller than is generally assumed. In patients with known myocardial bridging and symptoms that could be caused by myocardial ischaemia, it should first be established that the bridge is actually causing the ischaemia before any therapeutic intervention aimed at the bridge is undertaken.

Double orifice tricuspid valve in an infant with tetralogy of Fallot.

Atrioventricular valve duplication, also known as double orifice valve, is an excitingly rare anomaly that can involve either the mitral or more uncommonly the tricuspid valve. Herein we describe a case of a double orifice tricuspid valve that prejudiced the complete repair in a symptomatic infant with tetralogy of Fallot.
