A 54-year-old gentleman presented with pulmonary oedema secondary to anterolateral papillary muscle (PPM) rupture and acute mitral regurgitation subsequent to myocardial ischaemia (MI). Angiography revealed complete occlusion of the first obtuse marginal (OM1) branch of the circumflex coronary artery and a 70% occlusion of the left anterior descending (LAD) coronary artery. Operatively, unusual anatomy was noted; an accessory head was attached superiorly to the anterior lateral PPM. This gave rise to chordae that were subsequently attached to the posterior second (P2) scallop. Additionally, the P2 scallop was deficient in chordae from the posteromedial PPM, thus, loss of this accessory head led to severe mitral regurgitation. We review the PPM anatomy and pathological context of PPM rupture and ischaemic mitral regurgitation.

Objectives: To investigate the features of coronary artery lesions in patients over 50 with heart valve diseases and to find out the relationship between the levels of coronary artery lesions and heart valve diseases. Results: In patients over 50 year old with heart valve diseases, the rate of significant coronary artery lesions is 55.5%. In which, significant lesions in the group of both mitral and aorta valve diseases is 44.19%, only mitral valve diseases is of 70%, only aortic valve diseases is of 51.85%. There is a relationship between the severity of mitral valve diseases and right coronary artery lesions (OR 3.74: 1.64 to 8.5, p = 0.0017) and circumflex coronary artery lesions (OR 2.59: 1.16 to 5.75, p = 0.0192). The severity of heart valve lesions in significant coronary artery lesions group is higher than insignificant coronary artery lesions group or normal group. Conclusion: Coronary artery lesions is common in patients > 50 years old with heart valve diseases, there is a relationship between the severity of mitral valve diseases and and right coronary artery lesions and circumflex coronary artery lesions. Key words: coronary artery lesions, mitral valvediseases

<P>Background: Hypoplastic coronary artery disease is a rare congenital coronary artery anomaly. It is often detected incidentally, and its true incidence in the general population is not known. </P><P> Discussion: Symptoms of HCAD are syncope, palpitations, dyspnea, and chest pain. Also, arrhythmia and myocardial infarction can be seen; these can cause sudden death, especially in athletes and young people. Diagnosis is often made at autopsy. Conclusion: Here, we present the case of a 39-year-old male with isolated hypoplasia of the left circumflex artery detected by coronary Computed Tomography (CT) angiography who complained of palpitation.</P>
