Aim: Mitral stenosis (MS) is found to produce left ventricular (LV) dysfunction in some studies. We sought to study the left ventricular function in patients with rheumatic MS undergoing balloon mitral valvotomy (BMV). Ours is the first study to analyze effect of BMV on mitral annular plane systolic excursion (MAPSE), and to quantify prevalence of longitudinal left ventricular dysfunction in rheumatic MS. Methods: In this prospective cohort study, we included 43 patients with severe rheumatic mitral stenosis undergoing BMV. They were compared to twenty controls whose distribution of age and gender were similar to that of patients. The parameters compared were LV ejection fraction (EF) by modified Simpson's method, mitral annular systolic velocity (MASV), MAPSE, mitral annular early diastolic velocity (E′), and myocardial performance index (MPI). These parameters were reassessed immediately following BMV and after 3 months of procedure. Results: MASV, MAPSE, E′, and EF were significantly lower and MPI was higher in mitral stenosis group compared to controls. Impaired longitudinal LV function was present in 77% of study group. MAPSE and EF did not show significant change after BMV while MPI, MASV, and E′ improved significantly. MASV and E′ showed improvement immediately after BMV, while MPI decreased only at 3 months follow-up. Conclusions: There were significantly lower mitral annular motion parameters including MAPSE in patients with rheumatic mitral stenosis. Those with atrial fibrillation had higher MPI. Immediately after BMV, there was improvement in LV long axis function with a gradual improvement in global LV function. There was no significant change of MAPSE after BMV.

Background: Obese patients with established coronary artery disease have reduced mortality compared to normal or low body mass index (BMI) patients. The reason for the relation is not yet clearly understood. We sought to evaluate the association of BMI and waist circumference (WC) at the time of presentation in patients with myocardial infarction (MI) with one-year adverse cardiac events. Methods: In this prospective cohort study, we included consecutive patients with acute MI admitted to a tertiary care hospital during a period of one year. Upon admission, BMI and WC were measured. Patients were followed-up for a period of one year and the primary composite outcome of death or non-fatal MI was correlated with BMI and WC categories. Results: There were 703 patients (males 559 (79.5%)). Combined non-fatal MI and death at one year was 128 (18.2%). Incidence of primary outcome was 25.0% in low BMI group, 19.9% in normal BMI group, 13.1% in overweight group, 13.4% in class I obese, and 11.1% in class II obese groups. In univariate analysis, the inverse correlation was significant (p value = 0.007). In one-year follow-up period, 12.8% in high and 20.8% in normal WC groups had primary outcome (p value = 0.01). Both BMI and WC lost their predictive value in multivariate analysis. Conclusions: Low BMI and normal WC were associated with a worse short-term outcome in patients with acute MI. Neither BMI nor WC independently predicted cardiac events or death after acute MI.

Transfemoral balloon mitral valvotomy (BMV) is the standard treatment of severe symptomatic rheumatic mitral stenosis. However, in subjects with anatomic distortions, transfemoral BMV is difficult. We are presenting a case of severe rheumatic mitral stenosis who had a successful transjugular BMV using standard femoral hardware and Inoue balloon.

Background: Coronary sinus filling time (CSFT) has been proposed as a simple method for assessment of coronary microvascular function in patients with angina and normal coronaries. But its correlation with inducible ischemia and prognostic significance in predicting future cardiovascular events has not been studied. The present study assessed the prognostic significance of CSFT during one year of follow up. Methods: We compared coronary sinus filling time of patients with angina and normal coronaries with that of control population. Control group was formed by those patients with supraventricular arrhythmia undergoing radiofrequency ablation and having normal coronaries. Baseline treadmill test (TMT) parameters like workload, duration and Duke Score were assessed. Patients were followed up for one year and a composite of cardiovascular mortality and non-fatal myocardial infarction was analyzed. Number of patients presenting to emergency or outpatient department with recurrent chest pain symptoms during one year follow up was considered for secondary outcome analysis. Coronary sinus filling time was analyzed with respect to cardiovascular events, repeat hospitalization for recurrent angina and TMT parameters. Results: Total 72 patients and 16 controls were studied. Mean CSFT value in the study group was 5.31 ± 1.03 sec and in the control group was 4.16 ± 0.72 sec and the difference was significant (p value = 0.0001). No correlation was found between baseline and repeat TMT parameters with CSFT. There was no cardiovascular mortality or hospitalization for non-fatal MI during one year follow up. But patients with frequent emergency or outpatient department visits with chest pain had a high CSFT compared with asymptomatic patients (p value = 0.005). Conclusion: Coronary sinus filling time may be used as a simple marker of microvascular dysfunction in patients with angina and normal coronaries. Patients with recurrent chest pain symptoms after one year follow up were found to have high CSFT compared to asymptomatic patients.

Isolated chylopericardium due to cystic lymphangioma of pericardium is a rare entity. We report a case of asymptomatic chylopericardium in a young male who presented with cardiomegaly. Echocardiography revealed massive pericardial effusion without tamponade. Pericardiocentesis yielded 1.25 L of tea-colored fluid which showed triglyceride level of 1723 mg/dL and cholesterol of 1021 mg/dL with a cholesterol to triglyceride ratio of

We report a 42-year-old lady on combined oral contraceptive pills with deep venous thrombosis and mild pulmonary embolism, who developed shock, while being treated with heparin. On auscultation, there was an unexpected loud, superficial, squeaky, triphasic friction rub over the left lower parasternal area. Simultaneous echocardiogram revealed a large serpiginous, freely floating mass in right atrium, prolapsing freely to right ventricular inlet across the tricuspid valve. The endocardial friction rub persisted for about 24 h as long as the thrombus was intracardiac and disappeared when the thrombus disappeared from right heart, occluding the proximal left pulmonary artery. She died due to shock awaiting surgery. We highlight that such a rub in a patient with deep venous thrombosis, though rare, may be an important clue to impending pulmonary embolism.

Introduction: Percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) remains a challenge. The reasons being that these procedures may be lengthy and complex, with elevated radiation exposure, increased contrast load, lower procedural success rate, and a higher risk of complication when compared with non-CTO elective PCI.Clarifying the long-term clinical outcomes of CTO-PCI is very important to justify potential investments in training and technology. However, there is a paucity of data from Indian subcontinent. Hence we decided to report the outcomes from a real-life cohort of consecutive patients undergoing elective PCI for CTO at our institution., Materials and Methods: Single-center, prospective observational study. A total of 339 consecutive patients who underwent elective PCI for chronic total occlusion between Feb 2016 to Feb 2018 were included in the study. Procedural techniques, complications and clinical outcomes {all-cause death, cardiac death, major adverse cardiac events (MACE) and target vessel revascularization (TVR)} were assessed in our study population., Results: 339 patients were prospectively followed up for a duration that ranged from 3 months to 36 months, with a median follow up of 24 months. Overall procedural success was achieved in 85.5% (n = 290) cases. No significant differences were noted in In-Hospital adverse events (5.5% vs. 4.1%; p 0.998). MACE rate was significantly higher in unsuccessful CTO group (36.7% vs. 8.9%, p 0.001) and was predominantly driven by Ischemia Driven (ID) - Revascularization (16.3% vs. 3.1%, p < 0.001). Cardiac death and All-cause death was not significantly different between the groups. Residual angina (26.5% vs. 10%, p 0.003) and residual dyspnoea (34.7% vs. 12.4%, p < 0.001) were significantly worse in unsuccessful CTO group., Conclusions: Procedural success in the present drug-eluting stent (DES) era is more than 80% and newer techniques and hardwares have improved the procedural success rate, especially in younger age groups. MACE rates were significantly higher in the unsuccessful CTO group. Residual angina and dyspnoea were significantly worse in the unsuccessful CTO group., Competing Interests: All authors declared there is no conflicts of interest in this study and there is no grant and financial support to this study., (© 2020 Saudi Heart Association.)

Background: Intervention for bifurcation lesions is associated with increased risk of adverse events and includes acute side branch (SB) occlusion during main branch (MB) stenting. This acute occlusion of side branch can often be catastrophic for the patient. We here in describe our experience in Indian population with a technique which can be incorporated into bifurcation stenting to reduce or almost eliminate the incidence of side branch occlusion., Method and Results: 70 patients with bifurcation lesion were included in the study and underwent a balloon embedded bifurcation stenting with a semi inflated balloon placed across the SB ostium. Angiographic and procedural success were achieved in all the patients. TIMI 3 flow was achieved in both the MB and SB in all cases and there was no incidence of dissection or acute occlusion of SB. Mean fluoroscopy time and contrast volume was similar to that of conventional bifurcation stenting., Conclusion: The present study suggests that balloon embedded bifurcation stenting with a semi inflated balloon to protect the SB is feasible, not associated with procedural adverse events and successful in minimising or almost eliminating the incidence of acute side branch occlusion., (Copyright © 2018.

Background: Bifurcation lesions account for 15-20% of interventions carried out in a catheterization laboratory. Several techniques have been described for treating bifurcation lesions of which culotte and T-stenting and protrusion(TAP) are commonly used. Both these techniques involve recrossing the struts of primary stent, failing which the flow in second branch which can be impaired and lead to catastrophic events. In this study, we describe a novel balloon embedded stenting technique which can be incorporated with traditional culotte or TAP technique and facilitates conversion to bail out crush in case of such an event., Methods and Results: 28 patients who were treated with balloon embedded stenting for bifurcation lesions were included in the study. Angiographic and procedural success were achieved in all the patients. Primary stent could not be recrossed in 1 patient, who was successfully converted to bail out crush using the technique. There were no complications during the procedure. Mean fluoroscopy time and contrast volume was similar to that of conventional culotte and TAP., Conclusion: The present study suggests that incorporation of balloon embedded stenting into traditional culotte or TAP technique is achievable and can facilitate conversion to bail out crush when required., (Copyright © 2017.

Introduction: Advantages of vascular closure device over manual compression include patient comfort, early mobilisation and discharge, avoidance of interruption of anticoagulation, avoidance of local compression and its sequelae and less time constraint on staff. No published Indian data exist regarding Perclose Proglide suture mediated vascular closure device (SMC)., Aim: To study the 24h and 30 day outcome of Perclose Proglide SMC retrospectively., Study Design: Retrospective observational study conducted in the Department of Cardiology, Government Medical College, Calicut, Kerala from June 2013 to June 2015., Methodology: All consecutive patients with Perclose Proglide SMC deployment done by a single operator for achieving access site haemostasis where 24h and 30 day post-procedure data were available were included. Major and minor complications, procedure success, device failure were predefined., Results: 323 patients were analysed. Procedure success rate was 99.7% (322/323). Transient oozing occurred in 44 patients (13.6%), minor and major complications occurred in 2% and 1.5% of patients respectively. Major complication included one case of retroperitoneal bleed, one access site infection, one pseudo aneurysm formation and two access site arterial stenosis. There was no death or complication requiring limb amputation. "Preclose" technique was used successfully in six patients. Primary device failure occurred in 12 cases which were tackled successfully with second Proglide in all except one., Conclusion: Perclose Proglide SMC is a safe and effective method to achieve haemostasis up to 22F with less complication rate., (Copyright © 2016.

Background: Rheumatic mitral stenosis constitutes a major cause of acquired heart disease complicating pregnancy in India. In the present study, we have studied the fetal and maternal outcomes of women undergoing balloon mitral valvotomy during pregnancy., Methods and Results: 49 pregnant ladies were included in this study in whom balloon mitral valvotomy was performed. The mean age of these patients was 25.7±3.1 years. The mean gestational age was 23.5±5.2 weeks (12-36 weeks). The procedure was successful in 48 patients (95.9%). Mean two-dimensional MVA increased from baseline value of 0.93±0.17cm 2 to 1.75±0.27cm 2 (p value <0.0001). Pre-procedure peak pulmonary artery pressure was 43.05±15.88mmHg, which decreased to 22.31±6.36mmHg (p value <0.0001). Hemodynamic data showed pre-BMV left atrial mean pressure of 29.6±6.6mmHg, which decreased to 13.7±4.8mmHg after the procedure (p value <0.0001). Mean fluoroscopy time was 6.4±1.2min. There was no maternal mortality in our study. One procedure had to be abandoned, because of failed septal puncture. One of the patients developed cardiac tamponade and another patient developed severe mitral regurgitation, which were managed medically. The patient who developed severe mitral regurgitation later underwent mitral valve replacement. Post-procedure follow-up showed an improvement in NYHA status by at least one class in 81.3% of patients. Thirty-nine (81.3%) patients had a term normal vaginal delivery and 8 (16.7%) underwent cesarean section for obstetric indications. One of the patients had abortion on the second day of the procedure., Conclusion: Percutaneous mitral valvotomy during pregnancy is safe and provides excellent symptomatic relief and hemodynamic improvement. This should be considered as the treatment of choice when managing pregnant women with severe mitral stenosis., (Copyright © 2016 Cardiological Society of India. Published by Elsevier B.V.

Impaired longitudinal LV function was present in 77% of study group. MAPSE and EF did not show significant change after BMV while MPI, MASV, and E' improved significantly. MASV and E' showed improvement immediately after BMV, while MPI decreased only at 3 months follow-up., Conclusions: There were significantly lower mitral annular motion parameters including MAPSE in patients with rheumatic mitral stenosis. Those with atrial fibrillation had higher MPI. Immediately after BMV, there was improvement in LV long axis function with a gradual improvement in global LV function. There was no significant change of MAPSE after BMV., (Copyright © 2015 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.)

Background: Beta-blockers are frequently used in patients with mitral stenosis to control the heart rate and alleviate exercise-related symptoms. The objective of our study was to examine whether ivabradine was superior to atenolol for achieving higher exercise capacity in patients with moderate mitral stenosis in sinus rhythm. We also evaluated their effects on left ventricular myocardial performance index (MPI)., Methods and Results: Eighty-two patients with moderate mitral stenosis in sinus rhythm were randomized to receive ivabradine (n=42) 5mg twice daily or atenolol (n=40) 50mg daily for 6 weeks. Transthoracic echocardiography and treadmill test were performed at baseline and after completion of 6 weeks of treatment. Mean total exercise duration in seconds markedly improved in both study groups at 6 weeks (298.57±99.05s vs. 349.12±103.53s; p=0.0001 in ivabradine group, 290.90±92.42s vs. 339.90±99.84s; p=0.0001 in atenolol group). On head-to-head comparison, there was no significant change in improvement of exercise time between ivabradine and atenolol group (p=0.847). Left ventricular MPI did not show any significant change from baseline and at 6 weeks in both drug groups (49.8%±8% vs. 48.3%±7% in ivabradine group, 52.9%±10% vs. 50.9%±10% in atenolol groups; p=0.602)., Conclusion: Ivabradine or atenolol can be used for heart rate control in patients with moderate mitral stenosis in sinus rhythm. Ivabradine is not superior to atenolol for controlling heart rate or exercise capacity. Left ventricular MPI was unaffected by either of the drugs., (Copyright © 2015 Cardiological Society of India.

Aims: We sought to evaluate the correlation between PCWP and LAP and to compare transmitral gradients obtained with LAP and PCWP in MS, before and after balloon mitral valvotomy (BMV)., Methods: Consecutive patients with MS for BMV were included in this prospective cohort study. Simultaneous PCWP and LAP were recorded followed by simultaneous left atrium-left ventricular (LA-LV) and pulmonary capillary wedge pressure-left ventricular (PCWP-LV) gradients before and after BMV., Results: There were 30 patients with a mean age of 41 yrs (males 10 (33.3%), females 20 (66.7%)). There was no significant difference between mean LAP and mean PCWP before BMV (21.3mmHg and 22.3mmHg, respectively) or after BMV (15.3mmHg and 17.3mmHg, respectively). There was excellent correlation between mean PCWP and mean LAP before BMV (r=0.95) (p<0.001) and after BMV (r=0.85) (p<0.001). The phasic components of the pressures (a and v waves) of LAP and PCWP also showed good correlation before and after BMV. Further, transmitral gradients assessed by LA-LV and PCWP-LV pressures showed excellent correlation before BMV (r=0.95) (p<0.001) and after BMV (r=0.95) (p<0.001)., Conclusion: In patients with MS undergoing balloon valvotomy, PCWP shows good correlation with LAP. Transmitral gradients obtained with PCWP and LAP also correlate well after correction of phase lag in PCWP tracing. Hence, PCWP can be used for reliable measurement of transmitral gradient., (Copyright © 2015 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.)

Isolated chylopericardium due to cystic lymphangioma of pericardium is a rare entity. We report a case of asymptomatic chylopericardium in a young male who presented with cardiomegaly. Echocardiography revealed massive pericardial effusion without tamponade. Pericardiocentesis yielded 1.25 L of tea-colored fluid which showed triglyceride level of 1723 mg/dL and cholesterol of 1021 mg/dL with a cholesterol to triglyceride ratio of <1, characteristic of chylous fluid. Lymphoscintigraphy using 99Tc demonstrated lymphatic leak around the heart region. Fusion of MRI images with lymphoscintigraphy was taken with a view of localizing the leak site; it demonstrated enhancement in the pericardial space. Surgery was done via right lateral thoracotomy. Thoracic duct was ligated above diaphragm and pericardial window created by anterior pericardiectomy. The patient had an uneventful recovery and was well after 6 months of follow up. Pericardial biopsy showed cystic lymphangioma of pericardium., (Copyright © 2013 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.)

Background: Presence of right ventricular (RV) infarction imposes a higher risk of adverse events in inferior wall myocardial infarction (IWMI). In this study, we attempted to correlate various indices of RV function assessed by echocardiography with presence of a proximal right coronary artery (RCA) stenosis in patients with first episode of acute IWMI., Methods: In a prospective study, patients with first episode of acute IWMI underwent echocardiographic assessment within 24 h of symptom onset and indices of RV function viz. RV fractional area change (RVFAC), tricuspid annular plane systolic excursion (TAPSE), myocardial performance index (MPI) and tissue Doppler velocities from RV free wall were measured. Patients who underwent coronary angiogram (CAG) within one month and they were classified into group 1 and group 2 based on the presence or absence, respectively, of a significant proximal RCA stenosis., Results: There were 90 patients with first episode of IWMI of which 67 patients underwent CAG. There was significant difference between group 1 (n = 26) and group 2 (n = 41) in TAPSE (13.5 ± 1.3 vs 21.3 ± 1.7, p < 0.001), MPI by tissue Doppler (0.87 ± 0.1 vs 0.55 ± 0.2, p < 0.001) and in tissue Doppler systolic velocity from RV free wall (S' 9.8 ± 1.1 vs 15.0 ± 1.5, p < 0.001). There was a good interobserver correlation for TAPSE, MPI by TDI, and S' velocity. TAPSE ≤ 16 (sensitivity 93%, specificity 100%), MPI-TDI ≥ 0.69 (sensitivity 94.7%, specificity 93.5%), S ≤ 12.3 (sensitivity 90.3%, specificity 94.3%) were useful in predicting presence of proximal RCA stenosis., Conclusion: RV function indices like TAPSE, MPI-TDI and S' velocity are useful in predicting proximal RCA stenosis in first episode of acute IWMI., (Copyright © 2013 Cardiological Society of India.

Objective: Dysfunction of the coronary microcirculation is considered as one of the factors responsible for symptoms and abnormal stress tests in patients with angina and normal coronaries (syndrome X). We sought to evaluate the usefulness of coronary sinus filling time (CSFT) to assess coronary microcirculation in this group of patients., Methods: We compared the CSFT of patients having definite angina or atypical angina with positive treadmill electrocardiography test (angina group), with that of patients undergoing coronary angiogram (CAG) prior to balloon mitral valvuloplasty (control group). During CAG, coronary sinus was visualized in appropriate views and CSFT in seconds was derived from frame count. Thrombolysis In Myocardial Infarction (TIMI) flow grade, corrected TIMI (cTIMI) frame count, TIMI Myocardial Perfusion grade (TMP) were assessed., Results: There were 41 patients in angina group and 16 in control group. Among the angina group 68.8% were females as against 81.8% in the control group. 87.8% (n = 36) had typical angina. Mean CSFT was 4.25 ± 0.72 s and 3.46 ± 0.99 s in the angina group and control group respectively (p = 0.001). No significant differences were found between the groups with respect to TMP (p = 0.68) & cTIMI frame count (p = 0.22)., Conclusion: CSFT is a simple method to assess the transit time through coronary microcirculation. CSFT was significantly delayed in patients with angina and normal coronaries. TMP and cTIMI frame count were not significantly different between groups., (Copyright © 2013 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.)
