Item Entrapped catheter in the left ventricular posterior venous radicle of the coronary sinus in a case of hemianomalous pulmonary venous connection of left pulmonary veins to coronary sinus(INTERNATIONAL JOURNAL OF CARDIOLOGY, 2007) Krishnakumar, N; Misra, M; Dora, S; Bohora, SRA 25-year old acyanotic lady with unclear pulmonary venous drainage and a dilated coronary sinus was catheterized. Left pulmonary veins drained into coronary sinus in a left pulmonary vein angiogram done through the coronary sinus with a National Institute of Health 7F catheter. After the angiogram, the catheter got entrapped in a coronary sinus tributary and could be removed only by surgery. The left pulmonary veins were rerouted into the left atrium by unroofing the coronary sinus. Surgery is the treatment of choice for entrapped catheters when the primary condition itself merits surgical correction. (c) 2006 Elsevier Ireland Ltd.

The mitral valve showed the presence of calcium, and peripheral vascular disease was also present, though there was no family history of this. Aortic valve replacement was deferred because of insufficient data relating to this condition. The genetics and phenotypic mechanisms of the disease are reviewed. In view of the association of progeria with valve disease, all patients should undergo electrocardiography and echocardiography as part of their routine work-up.Item Rebuttal: Percutaneous Valvuloplasty for Mitral Valve Restenosis(CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, 2011) Nair, K; Sivadasanpillai, H; Sivasubramonium, P; Ramachandran, P; Tharakan, JA; Kumar, A; Sivasubramonian, S; Krishnamoorthy, KM; Dora, SItem Ventricular septal rupture following myocardial infarction. Long-term survival of patients who did not undergo surgery. Single-centre experience(ACTA CARDIOLOGICA, 2005) Pillai, HS; Tharakan, J; Titus, T; Kumar, A; Sivasubramonian, S; Mahadevan, KK; Dora, S; Nair, K; Namboodiri, NLong-term survival is rare in patients not undergoing surgery after post-myocardial infarction ventricular septal rupture. We report our experience of seven patients out of 27, who did not undergo surgery and were followed up for a mean period of 2.8years. They were evaluated after a mean period of 2.2 months after infarction in our centre. The septal defects measured 9.8 mms on average and the mean left-to-right shunt ratio was 1.98: L The mean pulmonary artery, right atrial and left ventricular end diastolic pressures were 28.3 +/- 10.6, 4 +/- 3 and 15.8 +/- 4.8 mm Hg, respectively. Only three out of seven patients had LV aneurysm and all patients had single-vessel disease. Smaller defect size, minimal left-to-right shunt and preserved right ventricular function may be the factors responsible for long-term survival.
