Morphological Study of Chordae Tendinae in Human Cadaveric Hearts |
p. 1 |
SA Gunnal, RN Wabale, MS Farooqui DOI:10.4103/1995-705X.152994 PMID:25838872Objectives: The chordae tendinae (CT) are strong, fibrous connections between the valve leaflets and the papillary muscles. Dysfunction of the papillary muscles and chordae is frequent. Mitral valve replacement with preservation of CT and papillary muscles may preserve postoperative left ventricular function better than conventional mitral valve replacement in patients with chronic mitral regurgitation.
Methods: The study was carried out on 116 human cadaveric hearts. The heart was opened through the atrioventricular valve to view the constituents of the complex. Origin, attachments, insertions, distribution, branching pattern and gross structure of CT were observed and studied in detail.
Results: In the present study more than 21 terminologies of CT were defined by classifying it into six different types. Classification is done according to the origin, attachments, insertion, distribution, branching pattern and gross structure. Terminologies defined are as follows. Apical pillar chordae, Basal pillar chordae, True chordae, False chordae, Interpillar chordae, Pillar wall chordae, Cusp chordae, Cleft chordae, Commissural chordae, First order chordae, Second order chordae, Free zone chordae, Marginal chordae, Rough zone chordae, Straight chordae, Branched-fan shaped chordae, Spiral chordae, Irregular-web chordae, Tendinous chordae, Muscular chordae, Membranous chordae. Basal pillar chordae are found in 9.48%. Mean number of chordae taking origin from apical half of a single papillary muscle or single head of papillary muscle was 9.09 with the range of 3-18. Mean number of the marginal chordae attached to a single cusp was 22.63 ranging from 11 to 35. Strut chordae showed interesting insertion with broad aponeurosis in 38.79% and large muscular flaps in 13.79%. Chordae muscularis were found in 14% and membranous chordae were found in 6%.
Conclusions: This knowledge may prove useful for cardiologists and cardiac surgeons. |

Assessment of Noninvasive Risk Markers of Subclinical Atherosclerosis in Premenopausal Women with Previous History of Gestational Diabetes Mellitus |
p. 13 |
Ritu Karoli, Zeba Siddiqi, Jalees Fatima, Vaibhav Shukla, Punj Prakash Mishra, Faraz Ahmad Khan DOI:10.4103/1995-705X.152995 PMID:25838873Introduction: Gestational diabetes mellitus (GDM) is state of carbohydrate intolerance detected first time during pregnancy. GDM represents a significant risk factor for the development of CVD in women. The degree to which women with histories of gestational diabetes are at risk for cardiovascular disease, beyond their predisposition to future diabetes, is still unclear. The aim of our study was to assess the presence of surrogate markers of subclinical atherosclerosis which can be present in them even without developing type 2 diabetes.
Subjects and Methods: In this descriptive cross-sectional hospital based study, 50 patients 20-45 yrs of age, premenopausal, at least 1 yr past her most recent pregnancy, and not more than 5 yr past her index pregnancy with GDM. These patients and controls who did not have GDM were assessed for carotid intima media thickness,endothelial dysfunction, epicardial fat thickness and other cardiovascular risk factors.
Results: Women with pGDM were found to have unfavourable cardiovascular risk parameters. They also demonstrated more frequent occurrence of metabolic syndrome(64% vs 10%) than control subjects. Individual components of MS increased with increasing BMI in both the groups. As far as markers of subclinical atherosclerosis were concerned women with pGDM had significantly higher CIMT, FMD and epicardial fat thickness than control group.
Conclusion: Women with pGDM, even before development of diabetes have significant differences in CVD risk factors when compared to those who do not have such history. Postpartum screening for glucose intolerance and efforts to minimize modifiable cardiovascular risk factors, including hypertension, viscerall adiposity, and dyslipidemia should be the most effective measures for lowering of cardiovascular risk. |

Superdominant Right Coronary Artery with Double Posterior Descending Artery
|
p. 19 |
Monika Maheshwari, SR Mittal DOI:10.4103/1995-705X.152996 PMID:25838874Coronary artery anomalies are rare entities. All angiographers and cardiac surgeons need to be familiar with these anatomic variants for proper surgical revasularisation in the presence of coronary artery disease. We report here an interesting case of superdominant right coronary artery with double posterior descending artery. |

Acute Myocardial Infarction in a Young Lady due to Vitamin B12 Deficiency Induced Hyperhomocysteinemia |
p. 25 |
Warkaa Al Shamkani, Nagham Saeed Jafar, Sunil Roy Narayanan, Anil Kumar Rajappan DOI:10.4103/1995-705X.152998 PMID:25838876Hyper-homocysteinemia is a risk factor for coronary artery disease in young patients. A 32 years old female without any conventional risk factors except obesity presented with acute anterior wall myocardial infarction (MI). Her echocardiography showed anterior wall hypokinesia with moderate left ventricular dysfunction. Angiography showed tight stenosis of the proximal left anterior descending (LAD) and borderline lesion in left circumflex coronary artery (LCX). She underwent percutaneous coronary intervention (PCI) to LAD with good result. Her blood tests showed low vitamin B12, folate and serum iron levels and elevated serum homocysteine level. She was given folic acid and vitamin B12 and her homocysteine levels normalized. This case demonstrates that hyperhomocysteinemia caused by nutritional deficiency of vitamin co factors may lead to MI. Hyperhomocysteinemia should be considered in the evalauation of young people with MI, especially those without conventional risk factors. |

Atypical Early Aspergillus Endocarditis Post Prosthetic Mitral Valve Repair: A Case Report |
p. 30 |
Ahmed AbdulAziz Abuzaid, Mahmood Zaki, Habib Tarif DOI:10.4103/1995-705X.152999 PMID:25838877A 64-year-old female operated 1 month previous for mitral valve repair presented with acute respiratory distress and dyspnea. Echocardiography showed large echogenic valvular mass measuring 2.3 × 1.3 cm with severe mitral regurgitation and dehiscence of the mitral ring posteriorly. The mass was attached subvalvularly to the ventricular septal-free wall and eroding through it, which required complete aggressive dissection of the infected tissues. Diagnosis was confirmed after resection of the valve by multiple negative blood cultures and positive valvular tissue for Aspergillus fumigatus endocarditis. She was treated with high dose of voriconazole for 3 months. Her postoperative period was complicated by acute-on-chronic renal failure. She responded very well to the management. |

Saphenous Vein Graft Perforation During Percutaneous Coronary Intervention - A Nightmare to be Avoided |
p. 34 |
Surender Deora, Sanjay C Shah, Tejas M Patel DOI:10.4103/1995-705X.153000 PMID:25838878Percutaneous coronary interventions (PCIs) of saphenous vein grafts (SVGs) is challenging and is associated with adverse short- and long-term clinical outcome as compared to native coronary arteries. SVG perforation is rare but catastrophic and needs immediate attention. Various factors predisposing for SVG perforation are old degenerated graft, ulcerated plaque, severe fibrotic, or calcified lesion necessitating high pressure balloon or stent inflation, use of intravascular ultrasound (IVUS) or other atheroablative devices. Management includes prolonged balloon occlusion, reversal of anticoagulation, use of covered stent, and emergency pericadiocentesis if required. |

Iatrogenic Left Main Coronary Artery Stenosis Following Aortic and Mitral Valve Replacement |
p. 37 |
Jadan Alsaddah, Saad Alkandari, Hany Younan DOI:10.4103/1995-705X.153001 PMID:25838879Iatrogenic coronary artery disease following prosthetic valve implantation is a rare complication. This may result from mechanical injury in the intraoperative period. The use of balloon tip perfusion catheter presumably provides the initial insult with local vessel wall hypoxia. Once the diagnosis of coronary ostial stenosis is established, the procedure of choice is coronary artery bypass surgery. We report a case of a young lady who underwent aortic and mitral valves replacement for infective endocarditis. She was then diagnosed with ostial left main stem coronary stenosis after presenting with atypical symptoms. The patient eventually underwent coronary artery bypass surgery. |
