Diffuse precordial ST-segment elevation in inferior-right myocardial infarction
A right ventricular (RV) myocardial infarction (MI) may yield precordial ST-segment elevation
(STE). Accordingly, combined inferior and precordial STE may be produced during an
inferior-RV MI. Such an electrocardiographic picture may be mistakenly regarded as showing
wrapped left anterior descending artery (LADA) occlusion or double vessel occlusion. We
present a patient with inferior-RV MI and STE in the inferior, all precordial and right chest
leads, in whom the diffuse precordial STE was probably mistakenly regarded as showing
anterior MI. However, the STE resolution in V1-V2 and late R’ wave in V1, which were
combined with a recanalized RV branch, favored the RV origin of this STE. Furthermore, the
LADA was patent when V3-V6 showed severe ischemia, while its lesion was angiographically
stable. Thus its simultaneous occlusion was unlikely. The late R’ wave in V1 indicates RV
transmural conduction delay;as highlighted herein, it is diagnostic of a RV myocardial infarction.

Microvascular Invasion Does Not Predict Long-Term Survival in Hepatocellular Carcinoma up to 2 cm: Reappraisal of the Staging System for Solitary Tumors
Background:
Excellent long-term outcomes have been reported recently for patients with small (≤2 cm) hepatocellular carcinoma (HCC). However, the significance of microvascular invasion (MVI) in small HCC remains unclear. The purpose of this study was to determine the impact of MVI in small HCC up to 2 cm.
Methods:
In 1,109 patients with solitary HCC from six major international hepatobiliary centers, the impact of MVI on long-term survival in patients with small HCC (≤2 cm) and patients with tumors larger than 2 cm was analyzed.
Results:
In patients with small HCC, long-term survival was not affected by MVI (p = 0.8), whereas in patients with larger HCC, significantly worse survival was observed in patients with MVI (p 2 cm without MVI, and HCC >2 cm with MVI—significant between-group survival difference was observed (p < 0.0001).
Conclusions:
Small HCC is associated with an excellent prognosis that is not affected by the presence of MVI. The discriminatory power of the 7th edition of the AJCC classification for solitary HCC could be further improved by subdividing tumors according to size (≤2 vs. >2 cm)
