Right ventricular postsystolic shortening: Resolution after opening a totally occluded right coronary artery

Acute myocardial ischemia induces reduced systolic shortening and causes postsystolic shortening (PSS). Right ventricular (RV) PSS in coronary artery disease has been less studied. We present here the case of a 51‐year‐old woman admitted with a non‐ST segment elevation myocardial infarction and sign...

description Acute myocardial ischemia induces reduced systolic shortening and causes postsystolic shortening (PSS). Right ventricular (RV) PSS in coronary artery disease has been less studied. We present here the case of a 51‐year‐old woman admitted with a non‐ST segment elevation myocardial infarction and significant PSS in the RV free‐wall segments on two‐dimensional speckle tracking echocardiography, suggesting ongoing ischemia. A cardiac CT demonstrated occluded proximal right coronary artery with a low‐attenuated/soft plaque, confirmed by coronary angiography which was treated by percutaneous coronary intervention. At 3‐week follow‐up, there was complete resolution of the RV‐PSS, with a more synchronized pattern of maximum myocardial shortening at systole.
