Comparison

Right coronary artery occlusion via… vs Baseline and recovery

Design

Case_series

Follow-up

1 minute after balloon deflation

Discussion

Implication

May support AVPD to detect acute RV dysfunction during RCA occlusion; hypothesis-generating pilot data requiring prospective validation before adoption.

Key Points

This study aims to assess whether acute right ventricular dysfunction can be detected using the AVPD method during coronary artery occlusion.
Pilot study involving seven patients undergoing elective proximal RCA angioplasty.
Echocardiographic measurements of RV AVPD were taken at baseline, during balloon inflation, and after deflation.
Comparison of lateral and medial RV AVPD values across different time points.
Lateral RV AVPD decreased significantly during balloon inflation from 2.45 cm to 1.77 cm (P < 0.001).
Medial RV AVPD decreased from 1.46 cm to 1.28 cm during inflation (P < 0.05).
Both lateral and medial RV AVPD values returned toward baseline during recovery, with lateral AVPD reaching 2.39 cm (P < 0.001) and medial AVPD reaching 1.58 cm (P = 0.01).

Structured PICO

Population

7 patients undergoing elective proximal right coronary artery (RCA) angioplasty

Intervention

Right coronary artery occlusion via intracoronary balloon inflation

Comparator

Baseline (immediately prior to RCA balloon inflation) and recovery (1 minute after balloon deflation)

Outcome

Right ventricular atrioventricular plane displacement (AVPD) measured by echocardiographysurrogate

Echocardiographic measurement of right ventricular atrioventricular plane displacement can serve as a sensitive surrogate marker for detecting acute right ventricular systolic dysfunction during right coronary artery occlusion.
