“…The addition of MCE to DSE has been investigated in the effort to improve the diagnostic accuracy of echocardiography for prediction of viability in patients with chronic ischemic heart disease [59]. In addition to improving endocardial border detection during echocardiography, MCE has an important role in evaluation of myocardial perfusion [37, 60].…”

“…MCE uses intravenously injected microbubbles that cross the pulmonary vascular bed, to reach the myocardial segments. The presence of microbubbles in a myocardial segment suggests viability while non-enhancement of the contrast estimates the absence of significant viability in that segment [59]. Microbubble velocity and myocardial blood flow, assessed by MCE, were found to be the most significant quantitative parameters for prediction of contractile reserve after MI [61].…”

Some patients with chronic ischemic left ventricular dysfunction have shown significant improvements of contractility with favorable long-term prognosis after revascularization. Several imaging techniques are available for the assessment of viable myocardium, based on the detection of preserved perfusion, preserved glucose metabolism, intact cell membrane and mitochondria, and presence of contractile reserve. Nuclear cardiology techniques, dobutamine echocardiography and positron emission tomography are used to assess myocardial viability. In recent years, new advances have improved methods of detecting myocardial viability. This paper summarizes the pathophysiology, methods, and impact of detection of myocardial viability, concentrating on recent advances in such methods. We reviewed the literature using search engines MIDLINE, SCOUPS, and EMBASE from 1988 to February 2012. We used key words: myocardial viability, hibernation, stunning, and ischemic cardiomyopathy. Recent studies showed that the presence of viable myocardium was associated with a greater likelihood of survival in patients with coronary artery disease and LV dysfunction, but the assessment of myocardial viability did not identify patients with survival benefit from revascularization, as compared with medical therapy alone. This topic is still debatable and needs more evidence.

“…In clinical practice, techniques based on nuclear imaging (SPECT and PET), contrast enhanced echocardiography, dobutamine stress echocardiography and magnetic resonance can be used to identify viable myocardial segments that can benefit from coronary revascularization [10][11][12][13][14][15][16][17][18].…”

“…Both patients presented deep inferior epigastric perforators, medially located, with normal flow. In head and neck cancer patients (3,4,5,8,9, and 13) with objective difficulties in recipient vessel selection due to radiation or previous operation (Table 1), PDU facilitated the design of the surgical plan, preoperatively. Specifically in patient 9 who presented severe actinonecrosis of the mandible and surrounding soft tissues, PDU demonstrated vessel depleted neck.…”

“…7 Also, in many cardiovascular diseases, diagnostic ultrasound has replaced invasive and more expensive methods as an evaluation measure. 8 Information provided by ultrasound techniques aid in determining the proper management approach in various surgical conditions. 9 Duplex ultrasonography has been used in reconstructive surgery to investigate blood flow in free flaps, 10,11 as well as, to monitor flaps either by means of implantable Doppler probes 12 or by means of usual ultrasound transducers.…”

Portable duplex ultrasonography: A diagnostic and decision‐making tool in reconstructive microsurgery

et al. 2010

Unidirectional Doppler is a common diagnostic tool by the Reconstructive Microsurgeons; however, it may generate false signals and surely provides less imaging data as compared to duplex ultrasonography. We have reviewed the use of Portable Duplex Ultrasonography (PDU) in 16 patients who underwent complex soft-tissue/bone reconstruction, aiming to determine its role in the design and management of free tissue transfer. According to our data, there were modifications either of the surgical plan and/or of patient's management, based on PDU findings, in 10 out of 16 patients (62.5%). The use of ultrasound directed to subtle modifications in three patients (19%), but to significant changes of the surgical plan in four patients (25%). Also, the use of ultrasound improved significantly the postoperative management in three patients (19%). Thus, significant impact of PDU in patient's treatment was recorded in 44% of cases. Portable ultrasound represents generally available method for preoperative, intraoperative, and postoperative diagnosis and decision-making in free tissue transfer, hence could replace in the near future the unidirectional Doppler in the hands of Microsurgeons.
