Left ventricular outflow tract pseudoaneurysm formation following three aortic valve replacement surgeries
Nasrien E Ibrahim, Angel Lopez-Candales
October-December 2015, 16(4):161-163
DOI:10.4103/1995-705X.172209  PMID:26900423
We present a case of a pseudoaneurysm arising from the left ventricular outflow tract/aortic root as a complication of aortic valve surgery. A 45-year-old Nigerian female presented to our institution's emergency department with chest discomfort. She had three bioprosthetic aortic valve replacements in the preceding year at an outside institution for aortic regurgitation and wanted a second opinion on remaining surgical options. The learning points relevant to this case are as follows: (1) Recognizing potential complications postmultiple valve surgeries, (2) screening patients for chronic infections and rheumatologic conditions that can contribute to failed valve surgeries.

Right bundle branch block and electromechanical coupling of the right ventricle: An echocardiographic study
Brian Edward Miller, Srinivas Rajsheker, Angel López-Candales
October-December 2015, 16(4):137-143
DOI:10.4103/1995-705X.172197  PMID:26900418
Background: A growing body of evidence suggests that the presence of a right bundle branch block (RBBB) is a negative prognostic indicator in patients with and without preexisting heart disease. Even though electromechanical activation of the right ventricle (RV) in patients with RBBB and pulmonary hypertension (PH) has been investigated; a direct comparison of the presence of RBBB, on the duration of RV mechanical systole using echocardiography has not been studied. Materials and Methods: In this retrospective study, we analyzed the echocardiograms of 40 patients by measuring the magnitude and timing of tricuspid annulus plane systolic excursion (TAPSE) and tricuspid annulus systolic velocity (TA S'). Patients were selected to form four groups of ten patients based on the presence or absence of RBBB and PH to determine if RBBB has any effect on the time-to-peak of TAPSE or TA S', which for our purposes serves as a measure of duration of RV mechanical systole. Results: Our results demonstrate that RBBB leads to a measurable prolongation of TAPSE and TA S' in patients without PH. Time-to-peak of TAPSE or TA S' was not significantly prolonged in patients with PH. Conclusions: The results of this pilot study show that RV mechanical systole is prolonged in patients with RBBB, and the addition of PH attenuates this change. Additional prospective studies are now required to elucidate further the electrical and mechanical dyssynchrony that occurs as a result of RBBB, and how these new echocardiographic measurements can be applied clinically to risk stratify patients with RBBB and PH.

Schwarz type C myocardial bridge unraveled post-thrombus aspiration in a patient with hypertrophic cardiomyopathy
Satyajit Singh, Aditya Kapoor
October-December 2015, 16(4):144-150
DOI:10.4103/1995-705X.172202  PMID:26900419
Hypertrophic cardiomyopathy (HCM), a heterogenous disease with diverse pathology and variable clinical course has a high prevalence of myocardial bridging. Despite the high prevalence of myocardial bridging in HCM patients, acute ST-elevation myocardial infarction (STEMI) due to concomitant atherothrombosis proximal to Schwarz type C myocardial bridge unraveled during trans-radial primary percutaneous intervention has rarely been reported in medical literature. Herein, we report a case of Schwarz type C myocardial bridge unmasked postthrombosuction in a patient with HCM presenting with acute STEMI. He had atherothrombosis proximal to the tunneled left anterior descending artery which was successfully stented with drug-eluting stent without the aid of intravascular ultrasound.

Noncompaction cardiomyopathy: Case presentation with cardiac magnetic resonance imaging findings and literature review
Mnahi Bin Saeedan, Ahmed L Fathala, Tan-Lucien H Mohammed
October-December 2015, 16(4):164-167
DOI:10.4103/1995-705X.172212  PMID:26900424
Left ventricular noncompaction cardiomyopathy is a very rare condition, yet believed to be often overlooked. It is thought to be caused by the developmental arrest in embryogenesis and characterized by an increase in the noncompacted, trabeculated myocardium adjacent to compacted myocardium in the left ventricular. The clinical presentations of this type of cardiomyopathy are of variable severity. Echocardiography used to be the diagnostic modality, but recent reports suggest that cardiac magnetic resonance imaging has higher sensitivity and specificity by showing a ratio of the noncompacted myocardium to compacted myocardium of >2.3.

A 20 year old female was referred to us for evaluation of effort dyspnoea of NYHA class II with feeble left common carotid, left brachial and left radial artery as compared to other sides. Detail evaluation with two dimensional (2D) transthoracic echocardiographic, 2D transesophageal echocardiography and multidetector computed tomography (MDCT) delineated Cleft AML and diffuse type of supravalvular aortic stenosis. To the best of our knowledge, no such case have been described in the literature where these anomalies co-existed in the same patient.

Retrieval of embolized intracardiac peripherally inserted central catheter line: Novel percutaneous technique by utilizing a flexible biopsy forceps
Arindam Pande, Achyut Sarkar, Imran Ahmed, Shailesh K Patil
October-December 2015, 16(4):154-157
DOI:10.4103/1995-705X.172204  PMID:26900421
Peripheral catheter embolization to the heart is common but infrequently reported. In view of the hazardous complications of thrombosis, embolism, infection, arrhythmia and even death, percutaneous retrieval of such foreign bodies is usually attempted. Previously reported percutaneous technique of retrieval mainly involved the snaring technique. Herein, we report a novel nonsurgical retrieval technique for successful removal of a 46 cm long embolized intracardiac peripherally inserted central catheter by utilizing a flexible biopsy forceps. To the best of our knowledge, the use of flexible biopsy forceps for retrieval has hitherto been unreported and this case report therefore adds to the repertoire of percutaneous retrieval techniques for safe and easy removal of embolized catheters to the heart.

Incidental spontaneous coronary dissection: An interventionist's dilemma
Akshyaya Pradhan, Safal Safal, Varun Shankar Narain, Rishi Sethi
October-December 2015, 16(4):158-160
DOI:10.4103/1995-705X.172205  PMID:26900422
Spontaneous coronary artery dissection (SCAD) is an uncommon entity, frequently presenting as ST-elevation myocardial infarction (MI) or sudden cardiac death. It is usually reported in association with pregnancy and has a high mortality. We present here a case of asymptomatic dissection of the right coronary artery, incidentally detected, in a young normotensive male when coronary angiography was done following acute anterior wall MI. This patient had none of the risk factors to which SCAD is generally ascribed. While management of the infarct-related artery was clear-cut, whether or not to intervene for this nonocclusive dissection was a difficult decision. A conservative approach was finally adopted for the spontaneous dissection and the patient is faring well till date.

Saurabh R Shrivastava, Arun G Ghorpade, Prateek S Shrivastava
October-December 2015, 16(4):131-136
DOI:10.4103/1995-705X.172195  PMID:26900417
Background: The World Health Organization (WHO) / International Society of Hypertension (ISH) risk prediction chart can predict the risk of cardiovascular events in any population. Aim: To assess the prevalence of cardiovascular risk factors and to estimate the cardiovascular risk using the WHO/ISH risk charts. Materials and Methods: A cross-sectional study was done from November 2011 to January 2012 in a rural area of Puducherry. Method of sampling was a single stage cluster random sampling, and subjects were enrolled depending on their suitability with the inclusion and exclusion criteria. The data collection tool was a piloted and semi-structured questionnaire, while WHO/ISH cardiovascular risk prediction charts for the South-East Asian region was used to predict the cardiovascular risk. Institutional Ethics committee permission was obtained before the start of the study. Statistical analysis was done using SPSS version 16 and appropriate statistical tests were applied. Results: The mean age in years was 54.2 (±11.1) years with 46.7% of the participants being male. On application of the WHO/ISH risk prediction charts, almost 17% of the study subjects had moderate or high risk for a cardiovascular event. Additionally, high salt diet, alcohol use and low HDL levels, were identified as the major CVD risk factors. Conclusion: To conclude, stratification of people on the basis of risk prediction chart is a major step to have a clear idea about the magnitude of the problem. The findings of the current study revealed that there is a high burden of CVD risk in the rural Puducherry.

Background: The implantable cardioverter-defibrillator (ICD) is effective in the prevention of sudden cardiac death in high-risk patients. Little is known about ICD use in the Arabian Gulf. We designed a study to describe the characteristics and outcomes of patients receiving ICDs in the Arab Gulf region. Methods: Gulf ICD is a prospective, multi-center, multinational, and observational study. All adult patients 18 years or older, receiving a de novo ICD implant and willing to sign a consent form will be eligible. Data on baseline characteristics, ICD indication, procedure and programing, in-hospital, and 1-year outcomes will be collected. Target enrollment is 1500 patients, which will provide adequate precision across a wide range of expected event rates. Results: Fifteen centers in six countries are enrolling patients (Saudi Arabia, United Arab Emirates, Kuwait, Oman, Bahrain, and Qatar). Two-thirds of the centers have dedicated electrophysiology laboratories, and in almost all centers ICDs are implanted exclusively by electrophysiologists. Nearly three-quarters of the centers reported annual ICD implant volumes of ≤150 devices, and pulse generator replacements constitute <30% of implants in the majority of centers. Enrollment started in December 2013, and accrual rate increased as more centers entered the study reaching an average of 98 patients per month. Conclusions: Gulf ICD is the first prospective, observational, multi-center, and multinational study of the characteristics and, the outcomes of patients receiving ICDs in the Arab Gulf region. The study will provide valuable insights into the utilization of and outcomes related to ICD therapy in the Gulf region.
