CONGENITAL ABSENCE OR HYPOPLASIA OF PULMONARY ARTERY

Congenital Absence of Left Circumflex Coronary Artery

Congenital absence of left circumflex artery is a rare congenital anomaly of the coronary arteries. The prevalence of the anomaly in different studies ranges from 0.6% to 1.3%. Of these, 80% are benign and asymptomatic and 20% are clinically important. We report a 56-year-old man presented with acute resting chest pain who was diagnosed as having acute anterolateral infarction accompanied by el...

Clinical Implications of Congenital Absence of Circumflex Coronary Artery

Introduction: Coronary artery anomalies are rare clinical entities reported in 0.6% to 5.6% of diagnostic coronary angiographies. Anomalous origins of coronary arteries from distal segments are rarely reported. Presented herein is a coronary anomaly in which the circumflex artery (CX) originated as a continuation of the posterolateral branch of the right coronary artery (RCA) w...

Unilateral pulmonary artery absence or hypoplasia; radiographic and cardiopulmonary studies in five patients.

The clinical entity of unilateral pulmonary artery absence or hypopl sia can be readily diagnosed on the basis of routine clinical evaluation. This report is based upon 5 patients in whom the diagnosis was suspected and eventually confirmed with the aid of special studies. Characteristic hemnodynainic findings were demonstrated by means of cardiac catheterization and contrast visualization of t...
