Mitral Stenosis, LV Aneurysm, Myocardial Bridge, and Myocardial Infarction: The Mystery Demystified.

Coronary embolisation, spontaneous coronary artery dissection, and myocardial bridges are rare causes of Myocardial Infarction (MI) in the youth. Here, we report a young male who developed myocardial infarction at the age of 19. Investigations revealed that he had mitral stenosis, myocardial bridge, and angiographic features of healed coronary dissection.

Trans-catheter closure of atrial septal defect: Balloon sizing or no Balloon sizing - single centre experience.

Background: Selecting the device size using a sizing balloon could oversize the ostium secundum atrial septal defect (OSASD) with floppy margins and at times may lead to complications. Identifying the firm margins using trans-esophageal echocardiography (TEE) and selecting appropriate-sized device optimizes ASD device closure. This retrospective study was undertaken to document the safety and feasibility of device closure without balloon sizing the defect.

Long-term functional assessment after correction of tetralogy of Fallot in adulthood.

Background: Tetralogy of Fallot presenting in adulthood is a surgical challenge. We present the long-term outcomes of surgical correction in this subset of patients, including results of postoperative effort tolerance as assessed by treadmill testing.

Methods: Fifty-eight patients older than 18 years operated on between January 1995 and June 2004 are included in the study.

Right ventricular pacing via left superior vena cava.

Negotiating the pacing lead into the right ventricle via left superior vena cava, at times, can be difficult. We report two such cases in which pacing leads were introduced into the right ventricle via left superior vena cava, with the help of stylet tip shaped into a large pigtail loop.

Novel deletions in MYH7 and MYBPC3 identified in Indian families with familial hypertrophic cardiomyopathy.

Mutations causing familial hypertrophic cardiomyopathy (HCM) have been described in at least 11 genes encoding cardiac sarcomeric proteins. In this study, three previously unknown deletions have been identified in the human cardiac genes coding for beta-myosin heavy chain (MYH7 on chromosome 14) and myosin-binding protein-C (MYBPC3 on chromosome 11). In family MM, a 3-bp deletion in MYH7 was detected to be associated with loss of glutamic acid in position 927 (DeltaE927) of the myosin rod.

Percutaneous coil closure of recanalised anomalous origin of left coronary artery from pulmonary artery.

An asymptomatic boy underwent surgical correction of anomalous origin of left coronary artery from pulmonary artery (ALCAPA) with trans-pulmonary artery interruption and saphenous vein grafting to left anterior descending coronary artery. He developed a shunt through the re-canalised pulmonary artery end of the ALCAPA which was successfully embolised using a detachable PDA coil delivered into the left main coronary artery from the pulmonary artery.
