Unexpected diagnosis: large hemangioma in the interatrial septum.

BACKGROUND: Cardiac hemangiomas are very uncommon benign primary tumors. They are usually located preferentially in the right atrium and their location in the interatrial septum is extremely rare. CASE PRESENTATION: We report the case of a 41-year-old patient who was admitted due to a stroke. The transthoracic echocardiogram revealed a large mass in the right atrium adhered to the interatrial septum. Suspecting an atrial myxoma, surgical intervention was performed confirming that the mass extended within the thickness of the interatrial septum, protruding into the right atrial cavity. The histologic report confirmed a hemangioma. CONCLUSIONS: Cardiac hemangiomas are rare primary tumors and are usually misdiagnosed as other cardiac tumors. Histopathological examination is essential for a definitive diagnosis.

Right ventricular failure: Current strategies and future development.

Right heart failure can be defined as a clinical syndrome consisting of signs and symptoms of heart failure resulting from right ventricular dysfunction. Function is normally altered due to three mechanisms: (1) pressure overload (2) volume overload, or (3) a decrease in contractility due to ischaemia, cardiomyopathy or arrythmias. Diagnosis is based upon a combination of clinical assessment plus echocardiographic, laboratory and haemodynamic parameters, and clinical risk assessment. Treatment includes medical management, mechanical assist devices and transplantation if recovery is not observed. Distinct attention to special circumstances such as left ventricular assist device implantation should be sought. The future is moving towards new therapies, both pharmacological and device centered. Immediate diagnosis and management of RV failure, including mechanical circulatory support where needed, alongside a protocolized approach to weaning is important in successfully managing right ventricular failure.

Coronary-subclavian steal syndrome: a case report of a rare entity that can become a deadly threat.

Background: In patients who underwent coronary artery bypass graft (CABG), the coronary-subclavian steal syndrome (CSSS) is characterized by a subclavian artery stenosis proximal to the origin of the internal mammary artery resulting in functional graft failure. Case summary: A 62-year-old gentleman underwent CABG following a non-ST elevation myocardial infarction and an angiogram showing left main stem and three-vessel disease. Forty-eight hours later he developed cardiogenic shock that improved with inotropic support and intra-aortic balloon pump insertion. However, 7 days later, he deteriorated again and even though the myocardial injury markers and echocardiogram were normal, an angiography was performed showing significant CSSS. Due to the chronic nature of his subclavian stenosis and the severity of the cardiogenic shock, the heart team decided to treated his epicardial disease percutaneously and occlude the left internal mammary artery in its mid-segment with coils. The patient was discharged home 28 days after CABG and has remained since asymptomatic with improvement in his functional class. Discussion: Coronary-subclavian steal syndrome is a rare but fatal complication with increased morbidity and mortality due to reduced awareness amongst medical professionals. Subclavian artery stenosis stenting is the gold standard treatment; herein we present a new approach for complex and very sick patients in whom it is not possible to open the subclavian artery percutaneously. Increased awareness and prompt diagnosis of this pathology in CABG patients are essential for successful outcomes.

Pulmonary artery sarcoma with extensive leiomyosarcoma differentiation and heterologous osteosarcomatous elements.

Pulmonary artery sarcomas are exceptionally unusual. Their clinic, diagnosis and treatment play a very important role in the ultimate outcome and long-term survival. We present the case of a 70-year-old gentleman diagnosed with a leiomyosarcoma of the pulmonary artery with osteosarcoma differentiation that underwent surgical resection and subsequent chemotherapy, with good recovery at 9 months follow-up. Late diagnosis and incomplete surgical resection will worsen the short- and long-term prognosis of these patients.

Perceval Less Invasive Aortic Replacement Register: multicentric Spanish experience with the Perceval S bioprosthesis in moderate-high-risk aortic surgery.

OBJECTIVES: The development of new percutaneous and surgical techniques has reduced the risk associated with aortic valve replacement procedures. We present the results of a Spanish register after initiating a programme for sutureless prostheses in moderate-high-risk patients. METHODS: This prospective multicentre study was carried out from November 2013 to November 2016. Data were obtained from 448 patients in whom a Perceval S prosthesis was implanted. RESULTS: The mean age was 79.24 (standard deviation [SD] 4.1) years, and 61.2% were women. The estimated EuroSCORE I log risk was 11.15% (SD 7.6), with an observed mortality of 4.4% (20 patients). Isolated aortic valve replacement was performed on 69.26% of patients, with 64% involving ministernotomy. The incidence of neurological events was 2%, with 2 permanent cerebrovascular accidents, and 41 (9.2%) patients were implanted with a permanent endocavitary pacemaker. At discharge, 12 (2.6%) patients presented minimal periprosthetic leakage, and 4 (0.89%) patients had moderate leakage. There were 3 reinterventions during follow-up (2 endocarditis and 1 dysfunction due to periprosthetic leak progression). The mean gradient at discharge, 6 months and 1 year was 12.94 (SD 5.3) mmHg, 12.19 (SD 4.7) mmHg and 11.77 (SD 4.7) mmHg, respectively; 59.4% of the patients were octogenarians, with a survival rate of 98% at both 6 months and 1 year at discharge. There was neither valve migration nor early structural degeneration. The mean follow-up was 12 ± 3 months. The 6-month and 1-year mortality was 1.4% and 2.1%, respectively. CONCLUSIONS: This is a prospective multicentric study on the largest cohort of patients with sutureless valves conducted in Spain to date. It is a reproducible procedure that has enabled surgery on patients with a moderate-high risk with low morbidity and mortality, providing good haemodynamic results.
