In this review, the role of nuclear imaging [particularly gated myocardial perfusion single photon emission computed tomography (GMPS)] for assessment of cardiac dyssynchrony is discussed. In addition, the role of positron emission tomography for evaluation of effects of CRT is addressed. Recent findings Phase analysis of GMPS yields accurate information on left ventricular dyssynchrony, correlating well with left ventricular dyssynchrony as derived from tissue Doppler echocardiography. Preliminary studies have also demonstrated that left ventricular dyssynchrony derived from GMPS can predict response to CRT (for histogram bandwidth and phase standard deviation sensitivity/specificity was 70 and 74%, respectively). Moreover, GMPS provides information on the location and extent of viable and scar tissue, which is also important for response to CRT. Furthermore, positron emission tomography studies have enabled quantification of cardiac perfusion (glucose and oxidative) metabolism and efficiency before and after CRT. Summary GMPS can provide important information for patients who are considered for CRT. This technique permits assessment of left ventricular dyssynchrony and viability/scar tissue, which are important for response to CRT. Positron emission tomography imaging may have a role in evaluation of physiologic effects after CRT, including myocardial perfusion, metabolism and efficiency.

Takotsubo Cardiomyopathy following Eye Surgery under Local Anesthesia – A Case Report

It manifests as acute coronary syndromes (ACS), but coronaries are usually normal and the majority recover completely without residual myocardial damage. Methods: We are reporting one such case, which followed laser therapy for glaucoma under local anesthesia. She fulfilled all the revised Mayo Clinic criteria for diagnosis. Her preoperative cardiac evaluation and computerized tomography coronary angiograms were normal. Results: This report highlights the need for a wide index of suspicion in those presenting as ACS. Surgical procedures however minor they are, even under local anesthesia should not be considered no-risk ones. Conclusion: Takotsubo cardiomyopathy is reversible acute cardiomyopathy that can occur even after minor eye surgery under local anesthesia. Patients may need coronary angiogram and serial echocardiogram at follow-up. It can be prevented by avoiding trigger factors, addr...

However, several pathological studies have indicated that DES may delay healing after vascular injury, and DES implantation may be theoretically associated with a risk of coronary artery aneurysm formation. Coronary aneurysms have been reported from 3 days to up to 4 years after DES implantation procedures, with varying clinical presentations. The incidence of coronary artery aneurysms after DES implantation is low within the first 9 months, with a reported incidence of 0.2% to 2.3%, a rate similar to that reported after bare-metal stent (BMS) implantation (0.3% to 3.9%) in the DES versus BMS randomized trials. However, the true incidence of coronary aneurysms in an unselected patient population is still largely unknown. This article reviews the published literature on coronary artery aneurysms specifically relating to

Coronary slow flow/no-reflow: Revisited
JOURNAL OF INDIAN COLLEGE OF CARDIOLOGY
No-reflow is defined as failure to restore normal myocardial perfusion despite removal of mechani... more No-reflow is defined as failure to restore normal myocardial perfusion despite removal of mechanical obstruction in the epicardial coronary arteries. This phenomenon is associated with high risk of major adverse cardiac events, recurrent heart failure, arrhythmias, and death. The degree of reperfusion injury depends on the duration of preceding myocardial ischemia, infarct size, procedure variables, and patient characteristics. This complication predominantly occurs during percutaneous coronary intervention for acute coronary syndrome. Cardiac magnetic resonance imaging is the gold standard noninvasive method for assessing this phenomenon. Conditions such as flow-limiting dissection, in situ thrombosis, severe spasm, or high-grade residual stenosis should be excluded prior to making a diagnosis of no-reflow phenomenon. The management of no-reflow should be personalized according to the predominant mechanisms contributing to the microvascular obstruction.

With optical coherence tomography plaque erosion (PE) can be detected in one third of cases. In young patients without major risk factors one can suspect PE. We are reporting one such case in whom stenting was deferred.

Post-licensure, observational, prescription event monitoring (PEM) study. 2162 patients received weight-adjusted Tenecteplase injection. The data for elderly (> 60 years) and non-elderly (< or = 60 years) was identified, segregated and compared. Out of 2162 patients, 805 were elderly patients and 1357 were non-elderly. Clinically successful thromolysis was seen in 83.98% of elderly and 86% of non-elderly group (p = 0.22). There was no significant difference in percentage of patients reporting bleeding, stroke, intracranial hemorrhage, myocardial reinfraction, ventricular tachyarrhythmia between the groups. Mortality was significantly (p = < 0.0001) more in elderly (6.21%) than non-elderly (2.06%) patients. The indigenously developed Tenecteplase shows high efficacy and safety in its in-hospital use in Indian elderly patients with STEMI.

Left ventricular mural thrombus following myocardial infarction--a follow up study

Thirty eight patients were males and mean age of study population was 52.4 years. Echocardiography revealed predominant mural type of thrombi (38 patients) and none showed mobility. All of them showed regional wall motion abnormality (RWMA) and Left Ventricular (LV) aneurysm was found in 28 patients. Embolic events were observed in 6 patients and 1 patient died following embolic stroke. Follow up study revealed persistent left ventricular thrombus in 19 patients and risk factors detected were severe LV dysfunction and LV aneurysm. Six patients had spontaneous resolution and 6 had resolution of the thrombus after anticoagulants. While anticoagulant therapy was very effective in preventing embolism after recent MI (within 3 weeks), it was found not useful in chronic LV thrombi. We observed ongoing embolic risk in chronic LV thrombi with LV aneurysm...
