Isolation of Left Subclavian Artery with Tetralogy of Fallot—A Case Report

引用

World Journal of Cardiovascular Surgery 2017年第2期7卷 11-15页

作者： anurag Agarwal Nayem Raja Akshay chauhan Muhammad Abid Geelani Saket Aggarwal Department of CTVS Govind Ballabh Pant Institute of Postgraduate Medical Education and Research (Gipmer) New Delhi India

Background: Isolation of Left Subclavian Artery (LSCA) is a rare subset of Right Aortic Arch (RAA). It is diagnosed as nonvisualization of LSCA in catheterization study. Case Presentation: Here we report an unusual case of Tetralogy of Fallot (TOF) with right aortic arch with isolation of left subclavian artery (LSCA). Here LSCA originated from left pulmonary artery (LPA) through an atretic patent ductus arteriosus (PDA). There was nonvisualization of LSCA in catheterization study and it was confirmed by Computed Tomography (CT) angiography. Re-implantation of LSCA was done to left common carotid artery (LCCA) so that the left upper arm maintains a better flow in the future. Conclusion: Isolation of LSCA especially with TOF is a very rare entity. Re-implantation of LSCA to LCCA was done in view of weak pulses in left upper limb. Results were satisfactory in the follow up period.

Fresh Pericardial Valved Conduit for Reconstruction of Right Ventricular Outflow Tract in Tetralogy of Fallot with Pulmonary Stenosis or Pulmonary Atresia—Early Results

引用

World Journal of Cardiovascular Surgery 2017年第2期7卷 16-25页

作者： anurag Agarwal Akshay chauhan Nayem Raja Chirantan Mangukia Saket Aggarwal Deepak Kumar Satsangi Department of CTVS Govind Ballabh Pant Institute of Postgraduate Medical Education and Research (Gipmer) New Delhi India

Objective: To study early results of hand made fresh (autologous/homologous) pericardial valved conduit in achieving right ventricle to pulmonary artery continuity. Method: Between November 2014 and September 2015, 19 cases, with diagnosis of Tetralogy of Fallot with Pulmonary stenosis (PS) or Pulmonary atresia (PA) underwent intracardiac repair and Right Ventricular Outflow Tract (RVOT) reconstruction with hand made fresh [autologous (n = 2)/ homologous (n = 17)] pericardial valved conduit. Mean age of the patients at time of surgery was 6.37 years (range 3 months to 18 years), mean weight was 18.52 kilograms (range 6 kg to 40 kg) and mean size of the conduit was 20.7 mm (range 16 mm to 24 mm). Results: All patients had a smooth post-operative course, with mean ICU (Intensive Care Unit) stay of 3.6 days (range 3 days to 6 days) and mean post-operative hospital stay 8.5 days (range 7 days to 16 days). Intra-operative and Post-operative echocardiography revealed moderate Pulmonary regurgitation (PR) in one patient, mild PR in 5 patients and no or trace PR in 13 patients. No patient has developed conduit stenosis or calcification till now. Conclusion: Autologous or homologous pericardial valved conduit provides good early results and is especially suitable for developing world because of zero cost. Long term usefulness of such option remains to be confirmed in terms of dilation, calcification and freedom from intervention.

Malignant Tumors of Heart: A Review

引用

World Journal of Cardiovascular Surgery 2018年第11期8卷 204-212页

作者： Akshay chauhan anurag Agarwal S. E. H. Naqvi M. A. Geelani Department of CTVS GB Pant Institute of Postgraduate Medical Education and Research Jawaharlal Nehru Marg New Delhi India Department of CTVS GBPH New Delhi India

Malignant cardiac tumors are rare and challenging entity. Experience in treating these aggressive and lethal tumors is minimal and management protocols are not well defined and have to rely on case reports, and personal experiences. Most effective therapy for primary cardiac malignancy is a complete surgical resection and the role of chemoradiotherapy is still evolving.
