RIGHT ATRIAL MASSES – A SERIES OF THREE CASES

Cardiac masses are rare, and they pose an interesting diagnostic and therapeutic challenge. The differentials vary from tumours – both primary and secondary, thrombus, infective vegetations, artifacts to cysts. They can present with obstructive symptoms, embolisation, constitutional symptoms or pericardial effusions. Multimodality imaging with echocardiogram, computed tomography (CT) and magnetic resonance imaging (MRI) help in diagnosis. Complete surgical resection is often the modality of choice in cases of tumours. Thrombolysis or surgical extraction is suitable in cases of thrombus in the right heart.

Study of immunogenicity, safety and efficacy of covishield vaccine among health care workers in a tertiary cardiac care centre

Purpose: The pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) might be curtailed by vaccination. We assessed the safety, and immunogenicity of Covishield vaccine among Health care workers (HCWs) in a tertiary cardiac care centre. Methods: It's a prospective analytical study, conducted at Sri Jayadeva Institute of cardiovascular science and research centre, Mysore, between January 2021 to May 2021. Pre and Post vaccination SARS CoV2 IgG antibodies were assessed among 122 HCWs. Interval between two doses in this study were 4 and 6 weeks. Adverse events following immunisation b(AEFI) and efficacy were assessed and followed up for two month post vaccination. Results: Post vaccination seropositivity was 69.67% in overall study participants. Seropositivity and P/N ratio median value in uninfected and infected group were 60.43% (n ¼ 55),3.47 (IQR: 2.56–5.22) and 96.77% (n ¼ 30),9.49 (IQR: 7.57–12.30) respectively (P < 0.001). Seropositivity and P/N ratio after 4 and 6 weeks were 48.3% (n ¼ 60), 2.95 (IQR: 1.91–4.24), and 83.8% (n ¼ 31), 4.88, (IQR: 3.39–6.43) respectively (P < 0.001). AEFI after first and second dose was 72.9% and 27.8% (p < 0.05) respectively. The most common symptoms after both doses of vaccination were local pain (73% & 88.2%), followed by fever (38.2% & 26.5%). The average duration of symptoms in both doses was 1.75 days. Of 122 participants only 10 (8.19%) had breakthrough infection after two doses of vaccination with mild severity. Conclusion: Covishield vaccine has showed seropositivity of 69.67%.It has acceptable level of safety profile. Seropositivity and P/N ratio has increased with increase in interval between two doses. Though it has not prevented breakthrough infection it has certainly reduced the severity of infection.

Effect of papaverine on left internal mammary artery flow: topical spraying versus perivascular injection method

Abstract Objective: To analyze two techniques of papaverine application, topical spray on the harvested left internal mammary artery (LIMA) and perivascular injection, to find out their ability to improve LIMA flow. Methods: Forty patients were randomized into two groups. In Group 1, papaverine was sprayed on the harvested pedunculated LIMA. In Group 2, papaverine was delivered into the perivascular plane. Drug dosage was the same for both groups. LIMA flow was measured 20 minutes after applying papaverine. Blood flow was recorded for 20 seconds and flow per minute was calculated. The systemic mean pressures were maintained at 70 mmHg during blood collection. The data collected was statistically evaluated and interpreted. Results: The LIMA blood flow before papaverine application in the Group 1 was 51.9±13.40 ml/min and in Group 2 it was 55.1±15.70 ml/min. Statistically, LIMA flows were identical in both groups before papaverine application. The LIMA blood flow, post papaverine application, in Group 1 was 87.20±13.46 ml/min and in Group 2 it was 104.7±20.19 ml/min. The Group 2 flows were statistically higher than Group 1 flows. Conclusion: Papaverine delivery to LIMA by the perivascular injection method provided statistically significant higher flows when compared to the topical spray method. Hence, the perivascular delivery of papaverine is more efficient than the spray method in improving LIMA blood flow.

Clinical course and prognosis of dilated cardiomyopathy in children

Background: Epidemiology and clinical course of dilated cardiomyopathy (DCM) in children and infants are not well established. Thus, this study aims to investigate the clinical course and prognosis of DCM in childrenMethods: This was a single-center, prospective, observational study conducted at a tertiary-care center in India between February 2011 and September 2012. A total of 31 patients admitted to the paediatric department diagnosed with DCM were included in the study. Patients were divided into three groups based on the age at the time of diagnosis: 0-3 years, >3-12 years and >12-16 years. Among the study population, 28 patients were followed up for a mean period of 1.44 years and three patients were lost to follow-up.Results: Of the 31 patients, 11 patients were male with a mean age of 8.9±6 years and 20 patients were female with a mean age of 8.3±6 years. All patients were presented with same characteristics of New York heart association (NYHA) class III-IV dyspnoea and fatigue. Among 28 patients who were followed-up for a mean period of 1.44 years, 20(71.4%) patients died and eight patients were on follow up. Of the eight patients, five patients were with NYHA class III symptoms and three patients were with NYHA class I-II symptoms.Conclusions: Dilated cardiomyopathy in children is a very serious disease with a grave prognosis. Patients with NYHA III-IV symptoms have a very high mortality rate and potential use of other therapies remains to be fully evaluated in paediatric population.

Successful retrieval of fractured pressure wire tip [FFR] by hybrid technique

Coronary angiography and angioplasty are relatively safe procedures but not without complications. We report an interesting case of effort angina taken for angioplasty of the LCX and assessment of fractional flow reserve [FFR] for the LAD artery lesion in which the tip of the pressure wire was broken and embolised to the LCX while trying to retrieve it. This is the first case report using a hybrid technique with a slip catheter for the successful retrieval of a fractured FFR wire

Myocardial FFR (Fractional Flow Reserve) in patients with angiographically intermediate coronary artery stenosis - an initial institutional experience.

RESEARCH ARTICLE January-March 2013 | Volume 1 | Issue 1 | Page: 4-11 Myocardial FFR (Fractional Flow Reserve) in patients with angiographically intermediate coronary artery stenosis - an initial institutional experience Jagadish H.

Ramaiah, Email: jagadishhr@rediffmail.com Background: The clinical significance of coronary artery stenosis of intermediate severity can be difficult to determine. The management of intermediate coronary lesions, defined by a diameter stenosis of ≥40% to ≤70%, continues to be a therapeutic dilemma for cardiologists. The 2-dimensional representation of the arterial lesion provided by angiography is limited in distinguishing intermediate lesions that require stenting from those that simply need appropriate medical therapy. In the era of drug-eluting stents, some might propose that stenting all intermediate coronary lesions is an appropriate solution. However, the possibility of procedural complications such as coronary dissection, no reflow phenomenon, in-stent restenosis, and stent thrombosis requires accurate stratification of patients with intermediate coronary lesions to appropriate therapy. Myocardial fractional flow reserve (FFR) is an index of the functional severity of coronary stenosis that is calculated from pressure measurements made during coronary angiography. The objective of the study is to evaluate the usefulness of FFR in patients with angiographically intermediate coronary artery stenosis. Methods: 20 patients with intermediate coronary stenosis and chest pain of uncertain origin. The Exercise Electrocardiography (TMT), Myocardial Perfusion Imaging study (MPI), Quantitative Coronary Angiography (QCA) were compared with the results of FFR measurements. Results: 20 patients were undergone FFR measurement during the study period. With the mean age of 57.25±11.2 and male patients were 16 (80%), female patients 4 (20%), in all 13 patients with an FFR of <0.75, reversible myocardial ischemia was demonstrated unequivocally on at least one noninvasive test. In contrast, 5 of 7 patients with an FFR of >0.75 tested negative for reversible myocardial ischemia on TMT and MPI study. No revascularization procedures were performed in 7 (35%) patients, and no adverse cardiovascular events were noted in all these patients during 6 months of follow-up. Conclusions: In patients with coronary stenosis of intermediate severity, FFR appears to be a useful index of the functional severity of the stenosis and the need for coronary revascularization
