Acute myocardial infarction is a recognized major complication of percutaneous transluminal coronary angioplasty (PTCA). Isolated right ventricular infarction is rare. A 60-year-old patient underwent PTCA 24 h following clinically successful thrombolytic therapy for an acute occlusion of a dominant right coronary artery. Following successful PTCA of this artery, a right ventricular branch was noted to be occluded. This was associated with chest pain, elevated venous pressure, S-T segment elevation in ECG leads V1-3, and a transient rise in serum creatine kinase. The clinical course was uneventful and a week later the right ventricular ejection fraction had increased from 18 to 36%. The long-term effects of right ventricular infarction are benign and occlusion of a right ventricular branch during PTCA is rarely of clinical significance.

“…1,[5][6][7] In terms of the ECG findings associated with acute inferior wall infarction, ST changes in precordial leads are often accompanied by ST depression, 8 which reflects the microscopic phenomena accompanying inferior wall infarction, the effect of the accompanying posterior wall infarction, or the effect of anterior wall myocardial ischemia. In the present case, the ST changes in leads II, III and aVF during PTCA were unclear, but marked ST elevation was confirmed in the contralateral precordial leads (V1-3), thus suggesting anteroseptal ischemia.…”

“…There are cases of isolated right ventricular infarction occurring as a result of occlusion of a side branch during PTCA, wherein ST elevation was confirmed in the II, III, aVF and precordial leads. [1][2][3][4] However, isolated right ventricular infarction is rare, accounting for only about 3% of all cases of infarction. In most cases, right ventricular infarction accompanies inferior wall infarction.…”

“…However, there are some cases where occlusion of a side branch during percutaneous transluminal coronary angioplasty (PTCA) of the proximal right coronary artery has induced right ventricular infarction and precordial ST elevation. [1][2][3][4] Right ventricular infarction usually accompanies inferior wall infarction, and rarely occurs alone, with such cases accounting for only about 3% of all cases of infarction. [1][2][3][4] We present a patient with transient isolated right ventricular branch ischemia occurring during PTCA of the right coronary artery and with marked ST elevation in the contralateral precordial leads.…”

n coronary artery disease, transient ST elevation in precordial leads generally indicates anteroseptal ischemia. However, there are some cases where occlusion of a side branch during percutaneous transluminal coronary angioplasty (PTCA) of the proximal right coronary artery has induced right ventricular infarction and precordial ST elevation. [1][2][3][4] Right ventricular infarction usually accompanies inferior wall infarction, and rarely occurs alone, with such cases accounting for only about 3% of all cases of infarction. [1][2][3][4] We present a patient with transient isolated right ventricular branch ischemia occurring during PTCA of the right coronary artery and with marked ST elevation in the contralateral precordial leads. Case ReportIn April 2000, the patient, a 64 year-old man, experienced cold sweats and chest pain, lasting approximately 20-30 min, while eating dinner. He believed he was having a hypoglycemic attack and took some glucose tablets. Because of severe malaise, the patient visited a neighborhood doctor the following day where electrocardiographic abnormalities were identified and consequently he was admitted to hospital that same day. He had previously been diagnosed with a Japanese Circulation Journal Vol. 65, February 2001 stomach ulcer in 1968 and diabetes in 1980. He had smoked 20 cigarettes a day for 40 years, and his father is a diabetic.The patient was 163 cm tall and weighed 67 kg. His blood pressure was 124/56 mmHg, and his pulse rate was 56 beats/min, regular and did not have a left -right difference. There were no abnormalities in his heart sounds, respiratory sounds or abdomen.The results of clinical tests on admission showed elevated white blood cell count (14,020/ l), aspartate aminotransferase (74 IU/L), and creatine kinase (883 IU/L). Chest Xray revealed a cardiothoracic ratio of 43.8%, and there were no abnormal findings in the lung fields. Electrocardiography (Fig 1)

“…Noninvasive studies demonstrate right ventricular dys function and wall motion abnormalities in many patients with acute inferior transmural myocardial infarction [1][2][3][4][5][6]. However, iso lated RVI according to the literature is a very rare condition [7][8][9][10][11][12]. We describe a case of isolated RVI who presented with ST eleva tion in the precordial leads mimicking an teroseptal myocardial infarction.…”
