Why the study?

What is the incidence and clinical outcome of acute coronary occlusion during coronary angiography?

Population

2981 patients undergoing coronary arteriography between January 1, 1970, and December 31, 1974

Comparison

Coronary arteriography using Sones or Judkins… vs Sones technique versus Judkins technique

Design

Cohort

Discussion

Implication

Technique-dependent occlusion rates support cautious catheter selection in angiography; leaves open questions on outcomes and modern applicability.

Key Points

To determine the incidence, procedural risk factors, and clinical management outcomes of acute coronary occlusion occurring during diagnostic coronary arteriography.
Retrospective cohort analysis of N=2,981 patients undergoing coronary arteriography between January 1, 1970, and December 31, 1974.
Compared acute complication rates between the Sones technique (n=2,077) and Judkins technique (n=940).
Evaluated clinical progression and survival across medical management (n=8) and emergency saphenous venous bypass grafting (n=4).
Acute coronary dissection or embolization occurred in 12 of 2,981 patients (0.40%), with an incidence of 0.19% (4/2,077) for the Sones technique versus 0.88% (8/940) for the Judkins technique.
Among 8 patients managed medically for right coronary artery dissections or circumflex emboli, all 8 survived, but 7 (87.5%) developed myocardial infarction.
Emergency bypass surgery was performed in 4 patients with left anterior descending artery occlusion; 3 survived to discharge, and all survivors sustained transmural myocardial infarctions despite revascularization in under three hours.

What is the incidence and clinical outcome of acute coronary occlusion during coronary angiography?

Population

2981 patients undergoing coronary arteriography between January 1, 1970, and December 31, 1974

Intervention

Coronary arteriography using Sones or Judkins techniques

Comparator

Sones technique versus Judkins technique

Outcome

Incidence of acute coronary dissections or embolizations (acute occlusions)safety

Acute coronary occlusion during coronary angiography is a rare complication (0.4%) but carries a high risk of myocardial infarction despite prompt medical or surgical treatment.
