Use of Tissue Doppler Imaging following Coronary Artery Bypass Surgery

This study assessed the effect of coronary artery bypass grafting (CABG) on myocardial systolic functions using tissue Doppler imaging (TDI). Fourteen patients (three women and 11 men) who had undergone isolated coronary bypass surgery were included in the study. Their mean age was 61 ± 8 years. TDI systolic velocity measures were obtained from four different sites on the left ventricular wall (anterior, septal, lateral and inferior) at the papillary muscle level in the parasternal short axis view before CABG, and then at 1 and 6 weeks post-operatively. There were significant increases in the myocardial wall velocities at all left ventricular sites 1 week after CABG. This increase persisted to week 6 after CABG, but the velocities were lower than week 1 values. We conclude that the ischaemic myocardium responded to surgical revascularization with marked increases in myocardial segmental systolic velocities in the early post-operative period.

Removal of the broken part of implantable cardioverter-defibrillator's electrode causing pulmonary embolism via femoral vein

A 66-year-old patient with idiopathic dilated cardiomyopathy underwent transvenous extraction of an implantable cardioverter-defibrillator. The distal part of the electrode was broken during manual traction through the left subclavian vein. In the present case, we showed a rare complication of transvenous lead extraction and its management.

Acute Proximal Aortic Intramural Hematoma: A Case Report

The case presented here is of a 72-year-old man with an acute proximal aortic hematoma. He was hospitalized and underwent close monitoring and blood pressure control. Typical aortic dissection developed during his hospital admission. This case emphasizes the importance of frequent follow-up imaging during medical therapy of patients with aortic intramural hematoma. However, the frequency of imaging is yet to be determined.
