ST segment depression after Norwood/systemic-pulmonary artery shunt

ST segment depression after Norwood/systemic-pulmonary artery shunt.

The haemodynamic significance of asymptomatic ST segment depression assessed by ambulatory pulmonary artery pressure monitoring.

A transducer-tipped catheter with simultaneous frequency modulated electrocardiograms and a miniaturised tape recorder was used to record ambulatory pulmonary artery pressure for 24-48 hours in 19 men (mean age 57.7) with clinical and angiographic evidence of coronary artery disease. Sixty seven episodes of ST segment depression (greater than 1 mm) were recorded. Thirty five were accompanied by...

Pulmonary artery stenosis after systemic-to-pulmonary shunt operations.

OBJECTIVE Systemic-to-pulmonary shunt operations are still required for palliation of certain congenital heart defects. The aim of this study was to analyze the incidence and etiology of the development of pulmonary artery stenosis after these procedures. METHODS AND RESULTS Pre- and post-operative angiograms of 59 patients who underwent 54 peripheral and 12 central shunt operations were anal...

Association of ST segment depression >5 min after exercise testing with severity of coronary artery disease.

OBJECTIVE To determine the association of prolonged ST segment depression after an exercise test with severity of coronary artery disease. METHODS A cross sectional study of 100 consecutive patients referred to the cardiology laboratory for stress myocardial perfusion imaging (MPI) conducted between April-August 2008. All selected patients were monitored until their ST segment depression was ...

Intrapericardial Aortico-pulmonary Artery Shunt.

SYSTEMIC arterv to pulmonary artery shunts for the alleviation of eyanotic heart diseases, especially tetralogy of Fallot, have utilized essentially the Blalock-Taussigl or the Potts2 3 technics. More recently Glen.n4 5 has advocated anastomosis of superior vena eava to right pulnmonary arterv in side-to-end fashion for patients with certain eyanotic heart coonditions. A shunt between the aseen...
