Visualization of HeartMate 3 Outflow Graft Twisting by Selective Graft Angiography.

A 55-year-old male patient presented with a history of left ventricular assist device (LVAD) implantation due to ischemic cardiomyopathy. Low-flow alarms were detected on the LVAD, which was temporarily stopped to demonstrate retrograde flow from the aorta through the outflow graft. Selective visualization was performed after engagement of a pigtail catheter in the outflow graft.

Left ventricular assist device implantation following multisystem inflammatory syndrome in children due to SARS-CoV-2.

Multisystem inflammatory syndrome in children (MIS-C) is rare, however, severe hyperinflammatory condition in children generally weeks after acute SARS-CoV-2 infection. A subset of MIS-C patients is presented with severe heart failure. We hereby report 8-year-old girl presenting acute severe left ventricular failure.

Surgical approach to recurrent secondary aortoenteric fistulas: A case report.

The increasing number of abdominal aortic grafts due to abdominal aortic aneurysms has caused secondary aortoenteric fistulas to be seen more frequently as a cause of gastrointestinal bleeding. High index of suspicion plays a significant role in the diagnosis in patients having clinical symptoms ranging from fecal occult blood to massive gastrointestinal bleeding, accompanied by hemorrhagic shock. A 65-year-old male patient developed two secondary aortoenteric fistulas consecutively.

Sutureless Aortic Valve Replacement.

Objective: To compare the results of sutureless aortic valve replacement (AVR) with the conventional method.

Study Design: A case-control study.

Place And Duration Of Study: Cardiovascular Surgery Unit, Istanbul Yeni Yuzyil University, Gaziosmanpasa Hospital, Turkey, from December 2014 to December 2019.

Outflow graft twisting of Heartmate III left ventricular-assisted device: A case report.

Outflow graft twisting of Heartmate III left ventricular-assisted device is a rare device complication and, due to the recent reports from transplant centers, the firm and the United States Food and Drug Administration have announced explanatory measures. When the outflow graft twisting occurs, the diagnosis and treatment should be done without any delay due to serious decline in the device output and unstable hemodynamics. This article describes the first case of an outflow graft twisting in Turkey.

Atrial Fibrillation Prediction by Surgical Risk Scores Following Isolated Coronary Artery Bypass Grafting Surgery.

Objective: To compare surgical risk scores including Euroscore II, STS and Logistic Euroscore for their predictive ability about postoperative atrial fibrillation (POAF).

Study Design: Prospective cohort study.

Place And Duration Of Study: Istanbul Yeni Yuzyil University, Gaziosmanpasa Hospital and Istanbul Mehmet Akif Ersoy Thoracic and Cardiovascular Surgery Center, from June to December 2018.

Endovascular stenting of mid-aortic syndrome due to Takayasu arteritis.

Introduction-patients: Takayasu arteritis may involve various parts of the aorta and its major branches. It leads to occlusive or aneurysmal disease of the vessel. It can be treated either with surgery or percutaneous intervention.

Timing of coronary artery bypass surgery in patients with non-ST-segment elevation myocardial infarction and postoperative outcomes.

Introduction: The aim of the study was to assess whether a cardiac troponin T (cTnT) level 1 ng/ml or below threshold is safe and to evaluate mid-term follow-up results in stable patients with non-ST-segment elevation after acute myocardial infarction.

Material And Methods: Among cTnT positive patients who presented to the emergency unit with chest pain and received coronary angiography, 100 patients who underwent isolated coronary artery bypass grafting (CABG) constituted the study group (group 1). The same number of patients (n = 100) who were cTnT negative and underwent an isolated CABG operation under elective conditions were selected as the control group (group 2).

Severe hypokalemia probably associated with sertraline use.

Objective: To report a case of ventricular fibrillation caused by severe hypokalemia probably associated with sertraline use.

Case Summary: A 48-year-old male patient experienced ventricular fibrillation and cardiac arrest 2 hours after an uneventful coronary angiography procedure, which revealed normal, unobstructed coronary arteries. Blood chemistry was immediately obtained, revealing a very low potassium (K+) level of 2.

Gastrointestinal complications after open heart surgery: incidence and determinants of risk factors.

Acute mesenteric ischemia is a rare but serious complication of open heart surgery. Between January 2009 and January 2012, 1360 adult patients underwent open heart surgery with cardiopulmonary bypass at our institution; 29 patients presented gastrointestinal complications. Eight patients developed acute mesenteric ischemia and all of them died.

Mesothelial/monocytic incidental cardiac excrescence in a patient with antiphospholipid syndrome.

Mesothelial/monocytic incidental cardiac excrescence (MICE) is a rare benign lesion composed of a mixture of histiocytes, mesothelial cells, fibrin, adipocytes and scattered inflammatory cells without a vascular network or supporting stroma. Its pathogenesis is controversial with some authors favoring an artifactual theory while others consider a reactive phenomenon. To date, only 41 cases of MICE have been reported in the literature.

Severe tricuspid regurgitation in a patient receiving low-dose cabergoline for the treatment of acromegaly.

Cabergoline, an ergot-derived dopamine receptor agonist, is used widely in the treatment of Parkinson's disease (PD) and hyperprolactinemia, but may cause heart valve fibrosis, retraction, and clinically significant regurgitation in PD patients. While cabergoline has been used at much lower doses in patients with hyperprolactinemia, controversy persists as to whether it may cause heart valve disease in this situation. Cabergoline is also used in acromegaly at doses similar to those used in hyperprolactinemia.

Factors associated with long-term survival following cardiac transplantation.

Objective: By improving short and long-term survivals, cardiac transplantation would be a more realistic curative treatment modality. The aim of this study was to evaluate factors associated with the long-term survival following cardiac transplantations in our center.

Methods: Forty-four patients were operated on cardiac transplantation between 1989 and November 2006.

Predictors and clinical significance of angiographically detected distal embolization after primary percutaneous coronary interventions.

Objectives: The aim of this study was to investigate clinical, angiographic and procedural predictors of distal embolization (DE) on angiography after primary percutaneous coronary intervention (PCI). The impact of DE on outcome in the first 30 days was also assessed.

Methods: Between January 2004 and April 2006, primary PCI was performed in 212 consecutive patients with acute myocardial infarction (AMI) of < or = 12-h duration.

Surgical treatment for late postoperative radial artery graft spasm.

Hemodynamic instability due to late postoperative radial artery spasm is a rare phenomenon. This entity developed in our patient who was operated on for severe left main coronary artery stenosis with a dominant circumflex artery. The spasm could not be relieved with intraluminal vasodilator therapy, and the patient underwent reoperation using a saphenous vein graft-anastomosed distal to radial artery.
