Right ventricular (RV) myxomas are extremely rare, but may have dreadful clinical sequelae including pulmonary embolism (PE). We present a case of a patient who had an RV myxoma that was attached to the tricuspid valve, and therefore could not be resected completely during surgery, and remnants of the tumor were seen on transthoracic echocardiogram during post-operative follow-up. Five months after surgery, the patient had PE, which could be due to tumor emboli or thromboemboli. Since repeat surgical resection was not feasible, the patient was started on warfarin...

Transcatheter aortic valve replacement in the setting of failed surgical bioprosthesis (valve-in-valve) is a valuable option for patients with bioprosthetic aortic stenosis or regurgitation who are deemed high risk for repeat open heart surgery. Although the procedure is successful with proper preprocedural assessment, instances of left main (LM) coronary artery ostium obstruction have been documented. We present a case of LM coronary obstruction in the immediate postoperative period following implantation of a 20-mm Edwards Sapien 3 valve inside the degenerated 21-mm Mitroflow bioprosthesis stenosis, which was treated with double stenting alongside the Edwards Sapien 3 valve creating a channel ("neo left main") that extended from mid-LM to the upper margin of the Edwards Sapien 3 valve...

PURPOSE: The failure rate of laparoscopic anti-reflux surgery is approximately 10-20%. The aim of our prospective study was to investigate whether a modified Nissen fundoplication (MNF) can improve reflux symptoms and prevent surgical treatment failure in the midterm. METHODS: The MNF consisted of (1) suturing the esophagus to the diaphragmatic crura on each side using four non-absorbable stitches, (2) reinforcing clearly weak crura with a tailored Ultrapro mesh, and (3) fixing the upper stitch of the valve to the diaphragm...

Introduction: Excess dilatation of the left atrium >65 mm is known in the literature as gigantic atrium. This dilation is most commonly encountered in the mitral insufficiency of rheumatic etiology, but also in severe prolapses of the mitral valve, permanent atrial fibrillation, and at the left right shunt with cardiac insufficiency. Case report: In this paper is presented a case study of echocardiographically verified giant thrombus in left atrium in a 50 years old female patient aged 50 hospitalized because of tiredness, choking, heartburn and urinary tract symptoms...

BACKGROUND: Mitral valve reoperation is necessary in a finite percent of patients. With growth in robotic mitral valve surgery, reoperative strategies need to be developed. A review of institutional mitral valve re-operations after a previous robotic approach was undertaken. METHODS: From January 2006 through April 2017, 1853 patients underwent an initial robotic mitral valve surgery by a dedicated robotic team. Fifty-four (2.9%) of these patients required mitral reoperation at our institution over this time period...

Objective: Reoperative mitral valve surgery is increasingly required and can be associated with significant morbidity and mortality. The beating heart minimally invasive mitral valve surgery has a proposed benefit in avoiding the risks of repeat sternotomy, with reducing the need for adhesiolysis and cardioplegia reperfusion injury. We describe our experience with such a technique in patients with previous sternotomy. Methods: A retrospective study was performed and all patients undergoing surgery of mitral valve through a right limited thoracotomy without application of an aortic cross-clamp (beating heart) as a redo cardiac surgery between January 2006 and January 2015 were included (n=25)...

OBJECTIVES: Persistent air leak or bronchopleural fistula (BPF) is a challenging and frequently observed problem after pulmonary resection and may lead to prolonged chest tube therapy. One efficient nonsurgical approach to manage such a fistula is the application of intrabronchial valves. This may support earlier chest tube removal and hospital discharge. METHODS: Between 04/2015 and 03/2017, n = 8 patients (n = 4 female) with severe pleural empyema and necrotising lung tissue defects developed prolonged air leak and persistent BPF after surgery...

We present a 22-year-old patient with a univentricular heart who had already undergone five open heart surgeries including a Damus-Kaye-Stansel procedure, Fontan completion and tricuspid valve replacement. In addition, epimyocardial pacemaker implantation and repeated revisions had been necessary. He developed symptomatic free regurgitation of the pulmonary portion of his DKS anastomosis. To avoid additional high-risk open-heart surgery, we successfully implanted an Edwards Sapien 3 valve transfemorally in the pulmonary portion of the DKS anastomosis relieving insufficiency...

Background: Bedside non-invasive techniques, such as radial artery tonometry, to estimate hemodynamic parameters have gained increased relevance as an attractive alternative and efficient method to measure hemodynamics in outpatient departments. For our pilot study, we sought to compare cardiac output (CO), and stroke volume (SV) estimated from a radial artery tonometry blood pressure pulse analyzer (BPPA) (DMP-Life, DAEYOMEDI Co., Gyeonggi-do, South Korea) to pulsed-wave Doppler (PWD) echocardiography derived parameters...

BACKGROUND: Late prognosis after successful percutaneous mitral commissurotomy (PMC) is unclear. We compared late results of PMC using Inoue versus double-balloon techniques up to 25 years in a randomized trial. METHODS: Between 1989 and 1995, 302 patients (77 men, 41 ± 11 years) with severe mitral stenosis were randomly assigned to undergo PMC using Inoue (n = 152; group I) or double-balloon technique (n = 150; group D). The end points were the composite events of death, mitral surgery, repeat PMC, or deterioration of New York Heart Association (NYHA) class ≥3...

BACKGROUND: The increasing numbers of glaucoma patients and complications occuring during treatment, such as restenosis and hypotony, require new treatment options to prevent blindness in patients. Therefore, the abovementioned problems should be solved to prolong the lifetime of implants and to prevent repeated surgery. OBJECTIVE: Can a novel stent with hyaluronic acid hydrogels (HA gel) as a functional unit be used to regulate pressure in glaucoma therapy in the long term? MATERIAL AND METHODS: Model stents were filled with HA gels and it was investigated if these could regulate the pressure and what the underlying mechanism is...

BACKGROUND: Transthoracic echocardiography (TTE) is one of the most commonly ordered tests in healthcare. Repeat TTE, defined as a TTE done within 1 year of a prior TTE, represents 24% to 42% of all studies. The purpose of this study was to derive a clinical prediction model to predict unchanged repeat TTE, with the goal of defining a subset of studies that are unnecessary. METHODS: Single-center retrospective cohort study of all hospitalized patients who had a repeat TTE between October 1, 2013, and September 30, 2014...

Transcatheter aortic valve replacement (TAVR) for aortic valve stenosis has rapidly progressed from its initial application in the inoperable or high-risk patients to those determined to be intermediate and low risk. It is our concern this has occurred without adequate knowledge or examination of the long-term durability of TAVR valves and the impact on subsequent aortic valve surgery, should it be required. In this editorial, we provide insight and reflect upon lessons learned from past surgical techniques and their subsequent abandonment...

BACKGROUND: Chronic kidney disease (CKD) is an adverse prognostic marker for valve intervention patients; however, the prevalence and related outcomes of valvular heart disease in CKD patients is unknown. METHODS AND RESULTS: Included patients underwent echocardiography (1999-2013), had serum creatinine values within 6 months before index echocardiogram, and had no history of valve surgery. CKD was defined as diagnosis based on the International Classification of Diseases, Ninth Revision or an estimated glomerular filtration rate <60 mL/min per 1...

OBJECTIVES: This study sought to assess the relative merit of surgical correction (SC) versus transcatheter reduction on long-term outcomes in patients with significant paravalvular leak (PVL) refractory to medical therapy. BACKGROUND: PVL is the most frequent dysfunction following prosthetic valve replacement. Although repeat surgery is the gold standard, transcatheter reduction (TR) of PVL has been associated with reduced mortality. METHODS: From 1994 to 2014, 231 patients underwent SC (n = 151) or TR (n = 80) PVL correction...
