“…Right atrial ischemia was defined according to accepted criteria in the literature: akinesis of the right atrial free wall in spite of the left atrial contraction, thrombosis at the site of akinesis, presence of spontaneous contrast in the right atrium, and inversion of the interatrial septal convexity. [14][15][16][17][18][19][20] Flow across mitral and tricuspid valves was not analyzed because of the difficulty involved in interpretation due to the high incidence of atrioventricular block and supraventricular arrhythmias.…”

“…Transesophageal echocardiography (TEE) fulfills these requirements and has greatly advanced the evaluation of ischemic heart disease as well as the extension of ischemia to the right chambers. [14][15][16] The purpose of this study was to examine a group of patients with inferior MI with extension to the right ventricle by TEE and to determine the relationship between the anatomic extension of the infarction in the right chambers and clinical and angiographic variables. Particular attention was devoted to the evaluation of the right atrium.…”

SummaryBackground: The role of the right atrium in adaptation to the hemodynamic changes produced by extension of myocardial infarction (MI) of the left ventricular inferior wall to the right ventricle is fundamental.Hypothesis: The aim of this study was analyze a group of patients with MI with extension of right chambers, and particularly right atrial alterations, by transesophageal echocardiography and to correlate it with clinical and angiographic variables.Methods: Thirty patients with right ventricular (RV) MI involving obstruction of the right coronary artery without stenosis of the left coronary artery were included; 18 underwent early reperfusion. Transesophageal echocardiography was performed on all within 5 days of coronary angiography. Follow-up was continued from hospitalization to the present.Results: When patients with right atrial ischemia were compared with those with normal right atrium, the RV wall movement score was significantly greater in the group with right atrial ischemia, severe RV dilatation was more frequent, and association with proximal occlusion of the artery responsible for the MI, as well as absence of right atrial branches and poor collateral circulation, were significant.

“…2 Recently, transesophageal echocardiography (TEE) with Doppler has been shown to be the noninvasive diagnostic technique of choice for evaluation of the anatomic and hemodynamic characteristics of the right atrium in patients with inferior infarction with extension to the right side of the heart. 3 This study examined the echocardiographic characteristics of a group of patients with acute myocardial infarction of the inferior wall of both ventricles, in whom the transesophageal study demonstrated akinesis or hypokinesis of the right atrial wall compatible with extension of the ischemic process to the atrium. TEE was repeated 15 to 55 months after the acute event, and the ndings were compared with the clinical evolution and coronary angiogram.…”

In order to determine the effect of right atrial dysfunction on clinical outcome, six patients with inferior myocardial infarction with extension to right ventricle and right atrium involving only obstructions of the right coronary artery were examined with transesophageal echocardiography (TEE) at the time of the event. Five of the patients were reexamined 15 to 55 months later. Two patients underwent thrombolysis and maintained ratios of right-to-left ventricular diameters of less than 1, as well as normal convexity of the interatrial septum. One patient had spontaneous reperfusion of the right coronary artery, reduction in right ventricular diameter, and normalization of interatrial septum. Another patient underwent delayed angioplasty and manifested a diminished wall movement score (WMS) in the follow-up echocardiogram. One patient died during his first hospitalization with significant right ventricular dilatation, inverted convexity of the interatrial septum, and right atrial thrombosis. The last patient died during follow-up with right ventricular dilatation, increased WMS, right atrial akinesis, and inverted interatrial convexity. Serial TEE examination of patients with infarction of the left ventricular inferior wall is a safe technique for determining the degree of the extension of the ischemic process to the right chambers.
