Duchenne muscular dystrophy (DMD) is a congenital X-linked muscular dystrophy, and cardiomyopathy typically develops in the second decade of life. In those patients with severe heart failure, the use of mechanical circulatory support is considered one of the treatment options, however, the decision to implant the assist device should be made after gauging the inherent risks and potential benefits. Transcatheter mitral valve repair (TMVr) is performed in adults with heart failure due to severe mitral regurgitation (MR) refractory to guideline-directed medical therapies. Data on MitraClip-based treatment (Abbott Vascular, Menlo Park, CA, USA) of young patients with cardiomyopathy-associated severe heart failure remain limited. We present the first report on the safety and effectiveness of TMVr with the MitraClip in an 18-year-old man with DMD and severe MR who was at a prohibitive risk for mitral valve surgery or left ventricular assist device therapy due to comorbidities. He was discharged without complications and, is now asymptomatic at one year after TMVr.

We describe a case of a 59-year-old woman with hypertrophic cardiomyopathy who remained with right ventricular outflow tract obstruction after the pressure gradient in the left midventricle was resolved by a drug with a negative inotropic effect. The patient was diagnosed with hypertrophic cardiomyopathy 30 years previously and was only on low-dose beta-blocker therapy. She presented at our hospital with suspected exacerbation of heart failure because of the development and exacerbation of dyspnea and chest tightness. Transthoracic echocardiography showed an accelerated blood flow of 3 m/s in the middle of the left ventricle; thus, she was started on
, a drug with a negative inotropic effect. After admission, intracardiac pressure measurement showed no pressure gradient in the left chamber. However, there was a pressure gradient of 18 mmHg between the apex of the right ventricle and the right ventricular outflow tract, and right ventricular outflow tract obstruction was confirmed on cardiac magnetic reson if the symptoms and auscultatory findings do not match the left ventricular imaging findings.
Interrupted aortic arch is a rare (prevalence 1100000) but malignant cause of secondary hypertension, with late sequela of early myocardial infarction, stroke, and heart failure. We present the case of a 49-year-old male patient with aortic interruption successfully treated by intravascular ultrasound guided transcatheter electrosurgical wire crossing and revascularization using a covered stent.

Transcatheter electrosurgical wire techniques utilizing intravascular ultrasound facilitate safe and effective percutaneous revascularization of complex aortic coarctation patients.

We performed a drug-coated balloon (DCB) angioplasty for severe pulmonary vein (PV) stenosis resulting from cryoballoon ablation for atrial fibrillation. Three and fourteen months after the angioplasty, follow-up multidetector computed tomography did not show restenosis. Lesion regression was observed at 14-month follow-up. Two years after PV angioplasty with DCB, the patient was well without any symptoms. DCB angioplasty may become an alternative effective procedure for PV stenosis.

The usefulness and safety of drug-coated balloon angioplasty for severe pulmonary vein stenosis resulting from cryoballoon ablation for atrial fibrillation was observed at 14-month follow-up.

Infective endocarditis (IE) is not a common disease, but it remains a serious condition. Antineutrophil cytoplasmic antibodies (ANCA) are often positive in IE, and discrimination between IE and ANCA-associated vasculitis is important because misdirected selection of therapy can lead to catastrophic consequences. We report a case of IE mimicking ANCA-associated vasculitis in which we were able to make a correct diagnosis and perform treatment. This case suggests that it is important to consider IE as a differential diagnosis in ANCA-positive patients.

Antineutrophil cytoplasmic antibodies (ANCA) are associated with primary systemic vasculitis. find more However, ANCA have also been described in other conditions and infective endocarditis (IE) was considered an important cause of ANCA.Discrimination between IE and ANCA-associated vasculitis is important, although it is sometimes difficult. We report a case of IE mimicking ANCA-associated vasculitis. ANCA-positive patients with nonspecific symptoms should be suspected of having IE, checked for heart murmurs, and tested by echocardiography and blood cultures.

With this case report we want to show how it is possible that a complicated ascending aortic aneurysm can mimic an acute pulmonary embolism/acute cor pulmonale in the acute phase; the earliest possible differential diagnosis between pulmonary embolism and acute aortic disease is of crucial importance due to the opposite implications that the treatment of these two diseases have. .
Both the diagnosis and treatment of coronary artery involvement with Takayasu arteritis (TA) are challenging. In this study, we report different clinical scenarios of two TA cases without Typical symptoms of TA that initially presented in the form of acute coronary syndrome (ACS). Patient 1 was a 24-year-old Japanese woman without coronary risk factors who presented with exertional chest pain, dyspnea, and syncope. Invasive coronary angiography (ICA) revealed a considerable lesion of the right coronary artery and the left main trunk. Ventricular fibrillation was observed immediately after the procedure. Despite conventional treatment, she died on day 16. Patient 2 was a 34-year-old Japanese woman without coronary risk factors who developed cardiogenic shock during a treadmill test for exertional chest pain. Coronary computed tomography angiography confirmed severe left main stenosis, presenting as ACS caused by TA. She was started on steroid therapy before coronary artery bypass grafting, resulting in a goosuspected of having TA initially manifest an unstable condition such as acute coronary syndrome.A 71-year-old female was diagnosed with cardiac sarcoidosis by a history of complete atrioventricular block requiring pacemaker implantation and a focal thinning of basal interventricular septum (IVS) on echocardiography. Coronary angiography showed a tumor-like blush fed by septal branch of left anterior descending artery and right coronary artery concomitant with a coronary-to-right ventricle shunt. Echocardiography showed a low echoic mass at mid-IVS with an abnormal shunt flow into right ventricle. Fluorodeoxyglucose (FDG)-positron emission tomography (PET) showed an uptake at the corresponding site of mid-IVS. Eight months after the initiation of steroid therapy, FDG-PET showed no abnormal uptake at mid-IVS, suggesting decreased activity of cardiac sarcoidosis. We experienced a case of cardiac sarcoidosis with FDG uptake accompanied by a tumor-like blush at mid-IVS. The present case suggests the involvement of microvascular accumulation in the activity of cardiac sarcoidosis. .Cardiorenal syndrome is the term that describes the interaction between the heart and kidney that leads to diuretic resistance and worsening renal function. Prolonged anuria generally represents irreversible renal failure, and recovery of renal function after prolonged anuria in patients with heart failure has rarely been reported. Moreover, increased central venous pressure including heart failure is associated with impaired renal function. We herein report a rare case of a 46-year-old man with dilated cardiomyopathy who presented with dyspnea and generalized edema. His body weight increased from 90 kg to 128 kg in one year and he was hospitalized. Central venous pressure (CVP) on admission was 33 mmHg. Intravenous catecholamines were not effective; thus, he was started on continuous hemodiafiltration. Anuria occurred after hemodiafiltration due to heart failure, sepsis, and antibiotics use. However, he experienced weight reduction of over 70 kg, under hemodialysis guided by central venous pressure measurement, and renal function recovery after 87 days of anuria. His CVP had improved to 5 mmHg at discharge. This case showed continuous trial to reduce the CVP and raise cardiac output could result in the recovery of impaired renal function even in the presence of prolonged anuria. .
A 42-year-old man with a history of acute myocarditis after streptococcal pharyngitis developed recurrent fulminant myocarditis. Endomyocardial biopsy revealed myocyte degeneration, interstitial edema, and neutrophil infiltration. The patient's cardiac function deteriorated rapidly, and he died despite mechanical circulatory support. Autopsy revealed neutrophil infiltration, interstitial edema, and micro-abscesses containing masses of streptococci and neutrophilic phagocytosis within the myocardium. The patient did not meet the diagnostic criteria for acute rheumatic fever; thus, he was diagnosed with non-rheumatic streptococcal myocarditis. Non-rheumatic streptococcal myocarditis rarely recurs, but it can be fulminant upon recurrence.
