Successful CTO intervention in such a scenario has only been sparsely reported. A 53-year-old-male smoker with severe resistant hypertension required multiple emergency admissions for flash pulmonary edema and aggressive blood pressure control. He was found to have deranged renal parameters with a serum creatinine of 2.4 mg/dL and an estimated glomerular filtration rate of 25 mL/min. His complete blood picture, metabolic panel, and inflammatory markers were within normal limits. Renal Doppler ultrasonography revealed bilateral severe renal artery stenosis and a contracted left kidney. Renal angiography showed total occlusion of both renal arteries with well-collateralized right kidney. He underwent right renal artery CTO angioplasty with stenting. Left renal artery occlusion was manag...

Transesophageal echocardiography (TEE) is the imaging modality of choice, however, is an underutilized investigation in routine clinical practice. We sought out to find the prevalence and severity of aortic arch atheromas in patients with cryptogenic stroke/transient ischemic attack (TIA) at a tertiary care center. Patients and Methods: One hundred and eighty-eight consecutive stroke patients were screened for stroke risk factors. Sixty-one patients were found to have stroke without obvious cause (cryptogenic), 52 patients underwent TEE, four patients were further excluded after evidence of potential cardioembolic source in TEE, and finally, data of 48 patients with cryptogenic stroke were analyzed. Results: We found that one-third of the patients (n = 16, 33.3%) had aortic atheromas and half of them (n = 8, 16.4%) had...

Early to midterm graft failure is still a significant problem in the clinical practice and often under reported. Here, we report a case of midterm failure of all grafts post CABG. A 56-year-old male presented to us with unstable angina and found to have triple vessel disease. He underwent CABG with left internal mammary artery (LIMA) to left anterior descending, venous grafts to diagonal and obtuse marginal. As ostial right coronary artery disease was moderate, it was not grafted. Three months later, he presented with acute coronary syndrome, acute heart failure, and moderate left ventricular (LV) dysfunction. Coronary and graft angiogram revealed critical anastomotic lesions of LIMA and both the venous grafts. Rapid progression of native vessel disease was also observed. He underwent successful multivessel percutaneous coronary interve...

Here the authors report a rare case of acquired long QT with R on T ventricular ectopics due to vasopressin in the setting of intracerebral bleed, which reverted on withdrawal of vasopressin.

There are fewer studies done in India 12-14 so little is known about the demographic pattern and predictors of severe disease in ACS, particular with NSTEMI. The natural history of significant stenosis of the left main coronary artery (LMCA) without revascularization treatment is associated with elevated mortality in patients with stable coronary disease (50% at 3 years) 15 as well as those with acute coronary syndrome (ACS) (78.6% in patients with acute myocardial infarction [AMI] complicated by cardiogenic shock) 16. Stenosis of the LMCA is more frequent in high-risk patients with NSTE-ACS5-17 ; hence, the possibility of predicting its presence is of maximum interest. The aim of this study, performed in patients with NSTE-ACS, no known history of ischemic heart disease, and classified as at high risk, was to analyze whether any of the clinical, electrocardiographic, or biochemical parameters we use to stratify risk in NSTE-ACS at hospital admittance is related with significant LMCA stenosis in the coronary angiography undertaken later in patients of costal Andhra Pradesh, India.
