Candida parapsilosis tricuspid native valve endocarditis: 3-year follow-up after surgical treatment

In non-addicted patients, several states such as alcoholism, previous valvular heart disease or prosthetic valve replacement, immunodeficiency states, prolonged intravenous hyperalimentation, permanent pacemakers, and some congenital heart diseases can provide the predisposing factors for tricuspid valve endocarditis. It is an extremely rare occurrence in patients with normal native cardiac valves. In this report, we present a case of a 67-year-old woman with tricuspid native valve endocarditis related to Candida parapsilosis which is a very rare cause of infective endocarditis and carries a high mortality risk. An operation was indicated for the patient due to persistent enlarging vegetation on tricuspid valve, severe tricuspid regurgitation, septic pulmonary emboli and finally uncompensated respiratory and heart failure. She underwent tricuspid valve replacement with bioprothesis three years ago and now she is in a satisfactory condition without any medical treatment.

A simple method for occlusion of both venae cavae in total cardiopulmonary bypass for robotic surgery.

We describe a novel surgical technique for occlusion of the superior and inferior venae cavae which allows opening of the right atrium safely during robotic cardiac surgery.

Robotic mitral valve replacement

Robotic surgical techniques allow surgeons to perform mitral valve surgery. This procedure has gained acceptance, particularly for mitral valve repair in degenerative mitral disease. However, mitral repair may not always be possible, especially in severely calcified mitral valve of rheumatic origin. This study demonstrates the basic concepts and technique of robotic mitral valve replacement for valve pathologies that are not suitable for repair.

Endoscopic-assisted Robotic Aortic Thrombectomy and Aortobiiliac Bypass: A Case Report

In this report, not only our experience with laparoscopy-assisted robotic aortic thrombectomy and aortobiiliac bypass procedure was presented but also current status of vascular interventions via endoscopically was discussed.

Transesophageal Echocardiography: Sine Qua Non In Cardiac Surgery

Objective: Intraoperative transoesophageal echocardiography (TEE) performed during cardiac surgery provides information about the cardiac pathology and the surgical repair. The aim of this study is to determine the importance of TEE in surgical decision making phase in patients undergoing cardiac surgery. Material and Method: We reviewed the data for all patients who underwent cardiac surgery and TEE between January 2015 and December 2016. Intraoperative TEE examination was performed before and after the cardiopulmonary bypass (CPB). The data collected related to the type of surgery, preoperative echocardiographic findings, TEE findings before and after CPB and any differences between them were evaluated. Results: A total of 284 patients who underwent cardiac surgery during 2 years period were evaluated using TEE. The initial TEE findings of 15.8% (n=45) of the patients differed from those observed before cardiopulmonary bypass (CPB). The results of the TEE assessments before and after CPB affected surgical decisionmaking in 3.5% (n=10) and 2.5% (n=8) of the cases, respectively Conclusion: Perioperative TEE performed by the anesthesiologist can provide important information, may lead to alterations in the surgical strategy and improve the operative outcomes.

Mirror Image Gerbode or Partial Atrioventricular Canal Defect

Gebode defect, that can accurately be treated surgical repair, is defined as a true communication between left ventricle and right atrium. A 74-year-old woman with a worsening history of ortophnea and peripheral edema was hospitalised. A communication between right atrium and left ventricle was diagnosed using transeusophageal echocardiography. The defect was repaired and mitral valve was replaced with a biologic valve. It would be beter to tailor surgical strategy for each case with atrioventricular canal defect after preoperative transeusophageal echocardiography and peroperative direct sight.

Robotic atrial septal defect closure

Atrial septal defect (ASD) is one of the most common congenital cardiac diseases. This pathology can be treated with percutaneous devices. However, some of the ASDs are not suitable for device closure. Also, there may be device-related late complications of transcatheter ASD closure. Currently, robotic surgical techniques allow surgeons to close ASDs in a totally endoscopic fashion with a high success rate and a low complication rate. This study demonstrates the basic concepts and technique of robotic ASD closure.

Long Term Results of Valve Sparing Aortic Root Replacement; A Single Center Experience

PP-044 The aim of this study is to investigate the early and midterm results of valve sparing aortic root replacements. Between 1999 and 2013 a total of 7220 patients underwent cardiac operations, 26 of them (0.3%) were valve sparing aortic root replacements. The aortic pathology included either
