A patient presented with symptoms of decompensated heart failure 2 months after percutaneous mitral valve (MV) repair. Echocardiography demonstrated impaired left ventricular function with elevated MV pressure gradients and pulmonary pressures during rapid atrial fibrillation. Heart rate control was achieved by implantation of a biventricular pacemaker with subsequent His-bundle ablation because atrial fibrillation was refractory to medical treatment. During biventricular pacing at different rates (50-110 b...

Osteoid osteoma of the atlas has previously been reported very rarely in the published literature. The traditional standard treatment has been a surgical resection of the nidus. Recently, computed tomography (CT)-guided radiofrequency ablation (RFA) has gained favor as a more precise alternative treatment. Here, we present a case of osteoid osteoma of the C1 lateral mass treated successfully using CT-guided RFA. A 30-year-old woman who presented with a four-month history of occipital and suboccipital pain was treated by CT-guided RFA...

Image-guided percutaneous thermal ablation has been one of the principal tools in management of unresectable liver malignancies, including colorectal liver metastases (CRLM) ( 1 ). Currently, however, this technique is suitable mainly for tumors less than 4-5 cm in diameter and also results in incomplete ablation at tumor margins ( 2 ). To solve these problems, efforts have been made to combine thermal ablation with other treatment options, such as systemic and intra-arterial administration of therapeutics ( 3 - 5 )...

Both surgical myectomy and percutaneous transluminal septal myocardial ablation are effective treatments for drug-refractory symptomatic hypertrophic obstructive cardiomyopathy (HOCM). However, in some cases, it is not easy to elucidate the abnormal structure of left ventricular outflow obstruction to adopt these treatments. Here, we presented a young female patient with drug-refractory symptomatic HOCM. In this case, contrast-enhanced computed tomography enabled us to assess the suitability of percutaneous transluminal septal myocardial ablation...

BACKGROUND: Metastases to the bone are common in cancer patients, and it has been estimated that up to 50% of patients with pelvic bone metastases will not achieve adequate pain control with medications alone. This has led to a paradigm shift over recent years towards the use and development of minimally invasive image-guided treatment options for palliation of bony metastases. Despite these developments, large metastatic lesions are still often considered to be "hopeless cases" that would garner little to no benefit from image-guided intervention...

Spinal metastases are the most commonly encountered tumour of the spine, occurring in up to 40% of patients with cancer. Each year, approximately 5% of cancer patients will develop spinal metastases. This number is expected to increase as the life expectancy of cancer patients increases. Patients with spinal metastases experience severe and frequently debilitating pain, which often decreases their remaining quality of life. With a median survival of less than 1 year, the goals of treatment in spinal metastases are reducing pain, improving or maintaining level of function and providing mechanical stability...

BACKGROUND: Laparoscopic sleeve gastrectomy is a common surgical management of morbid obesity. Major complication rate is 3-8%. Staple line leak is one of the most serious complications. In a small group of patients, a gastro-pulmonary fistula is formed. Endoscopic and minimally invasive measures are the first line of treatment with considerable success rate. There are very poor data in the literature what should be done in cases of failure. In this paper, we report our positive experience with definitive surgical repair...

We present the case of a 69-year-old patient who was referred to the Department of Echocardiography for surgical treatment of severe tricuspid valve regurgitation (TVR) with advanced congestive heart failure. In 2013 the patient underwent unsuccessful percutaneous ablation for permanent atrial fibrillation. In 2015, following numerous episodes of atrial fibrillation and congestive heart failure with left pleural effusion, the patient was admitted to another center. A transthoracic echocardiogram showed severe TVR and moderate precapillary pulmonary hypertension, confirmed at right cardiac catheterization...

Ectopic adrenocorticotropic hormone (ACTH)-related Cushing's syndrome can lead to multiple complications including severe immunosuppression. If the ACTH-secreting tumour cannot be found, definitive treatment is surgical adrenalectomy, typically followed by glucocorticoid replacement. Here, we present a case of fulminant respiratory failure secondary to coinfection with Pneumocystis jirovecii and cytomegalovirus in a patient with ectopic ACTH-dependent Cushing's syndrome with occult primary. Due to significant deconditioning, she was unable to undergo definitive adrenalectomy and instead underwent percutaneous microwave ablation of the adrenal glands...

Percutaneous coronary intervention (PCI) for patients with in-stent restenosis (ISR) is generally considered safe and effective. However, due to increased tissue hardness, PCI for calcified intra-stent ISR is technically challenging. Here, we report severe angioplasty-related complications in a patient presenting with calcified, recurrent ISR following PCI. After receiving drug-coated balloon (DCB) angioplasty for an initial ISR, the patient developed recurrent ISR during the follow-up period. Intravascular imaging revealed intra-stent calcifications and balloon angioplasty was subsequently performed...

Hepatocellular carcinoma (HCC) is the second leading cause of death by cancer worldwide. Resection and liver transplantation are the gold standards, but only a minority of people are eligible. Percutaneous ablation therapies, such as microwave ablation (MWA), have consequently been developed. There is a lack of guidelines regarding the treatment of HCCs in end-stage renal disease (ESRD) patients. Here, we report the case of a 67-year-old patient who was undergoing peritoneal dialysis (PD) for chronic congestive heart failure and who presented with an HCC while undergoing PD...

Percutaneous and endovascular techniques take an important role in the therapeutic management of patients with hepatocarcinoma. Different techniques of percutaneous ablation, especially indicated in tumors up to 2cm diameter offer, at least, similar results to surgical resection. Taking advantage of double hepatic vascularization and exclusive tumor nutrition by the artery, several endovascular techniques of treating the tumor have been developed. Intra-arterial administration of embolizing particles, alone or charged with drug (chemoembolization), will produce ischemia and consequent necrosis with excellent results in selected patients...
