Acute coronary disease is a rare entity in young people and is mostly related to atherosclerotic disease. However, other causes such as myocardial bridges, coronary artery dissection and antiphospholipid syndrome may be present. The prognosis of the disease in this group of patients is favorable; although women may have a higher morbidity because diagnosis and treatment can be delayed. The goal of this review is to update the knowledge about risk factors and prognosis of young patients with an acute coronary event compared to the older population...

Actuator-driven pulsed water-jet (ADPJ) dissection is an emerging surgical method for dissecting tissue without heat and mechanical injury to vessels. We elucidated the mechanical properties of the piezo ADPJ and evaluated its usefulness and safety in coronary artery bypass grafting procedures. The relationship between the input voltage (10-100 V) and peak pressure of the pulsed water jet was evaluated. The tissue strengths of swine internal thoracic and coronary arteries and the surrounding tissues were measured to assure tissue-selective dissection...

The transfemoral arterial approach is used to gain access for angiography, percutaneous coronary interventions, or various endovascular therapies. To decrease the risk of procedure-related vascular complications, it is recommended to puncture the common femoral artery in its middle segment. However, due to inadequate access or anatomical variability, various complications, including hematoma, pseudoaneurysm, arteriovenous fistula, thrombosis, or dissection, can occur after transfemoral arterial interventions...

Cardiovascular disease is an important cause of morbidity and mortality during pregnancy and the postpartum period. During pregnancy, the cardiovascular system undergoes extensive hemodynamic, hormonal, and microstructural changes which may exacerbate a preexisting underlying cardiovascular condition or predispose to cardiovascular complications not typically seen in young healthy women. Such conditions include spontaneous coronary artery dissection, atherosclerotic coronary artery disease, and peripartum cardiomyopathy...

BACKGROUND: Although the incidence of periprocedural complications has decreased in transcatheter aortic valve implantation (TAVI), life-threatening complications occur and emergency veno-arterial extracorporeal membrane oxygenation (vaECMO) can provide immediate circulatory stabilization. We report our two-center experience of vaECMO during life-threatening complications in TAVI. METHODS: From January 2010 to December 2015, 1,810 consecutive patients underwent TAVI at two centers...

BACKGROUND: Interleukin (IL)-22 plays important roles in the development of arterial disease, including atherosclerosis and hypertension. However, the relationship between IL-22 and acute thoracic aortic dissection (TAD) remains unknown. METHODS: Blood samples were collected from patients with chest pain who underwent computed tomography angiography of the thoracic aorta but had no known preoperative diagnosis of coronary artery disease, peripheral artery disease, arthritis, and/or membranous nephropathy...

Coronary venous dissection is a known complication of left ventricular lead placement during implantation of a cardiac resynchronization with defibrillator (CRT-D) system. A large-scale evaluation of the prevalence of coronary venous dissection and associated in-hospital clinical outcomes has not been performed. We sought to identify predictors of coronary venous dissection and evaluate subsequent in-hospital adverse events in those with the complication. We studied 140,991 first-time CRT-D recipients in the implantable cardioverter-defibrillator (ICD) Registry implanted between 2006 and 2011...

In this paper, we report the autopsy findings of a 42-year-old White male who was found deceased at his home by his brother in the early morning hours with a history of excessive alcohol consumption 1 day before his death. A medical record review revealed chronic alcohol use with alcohol dependence syndrome, hypertension, and cardiac arrhythmias by electrocardiogram 2 years prior. External examination revealed only a single bruise on the forehead. Internal examination revealed changes associated with chronic alcohol abuse and mild atherosclerosis...

Medical history We report on a 51-year-old male patient with thoracic pain of acute onset with radiation in the left arm. His cardiovascular risk factors include obesity, smoking and arterial hypertension. Investigations ECG showed no signs of ischemia. The blood test revealed increasing troponin (37 pg/ml; Norm < 14 pg/ml). Therefore we performed cardiac catheterization. The RIVA demonstrated a medial filling defect. Use of OCT imaging showed intimal rupture associated with thrombus. Treatment and course The lesion was stented with a drug eluting stent...

BACKGROUND: Data on the impact of coronary chronic total occlusion (CTO) percutaneous coronary intervention (PCI) on quality of life (QOL) are limited. To date, studies have been limited in sample size and have focused on only a few domains of the Seattle Angina Questionnaire (SAQ). We evaluated the relationship between coronary CTO PCI and QOL in patients with symptoms of angina, incorporating all aspects of the SAQ. METHODS: The SAQ was used to interrogate patients at baseline and at 12 months after CTO PCI...

BACKGROUND: Aortic dissections can present with a broad spectrum of signs and symptoms, making them difficult to diagnose in the emergency department (ED). Aortic dissections can cause occlusion of the coronary arteries, mimicking an acute ST-elevation myocardial infarction (STEMI). Emergency point-of-care ultrasound (POCUS) may be a useful diagnostic tool to help differentiate aortic dissection from a primary myocardial infarction. CASE REPORT: A 69-year-old man with no medical history presented to our ED complaining of chest pain...

BACKGROUND: Guide catheter extension systems have become one of the most powerful tools for addressing complex lesions during percutaneous coronary intervention (PCI), but data on a new-generation rapid exchange extension catheter - the Guidezilla catheter - are limited. Summarized herein reports on experience using the Guidezilla catheter for complex coronary lesions via a transradial approach at the documented institution an evaluation of its safety and efficacy. METHODS: A total of 25 patients (19 males and 6 females) who underwent PCI via the radial approach with the Guidezilla catheter for adequate back-up support and to facilitate equipment delivery were enrolled...

Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute coronary syndrome in young patients. No clear factors exist to predict the natural history of the disease and the prognosis of the condition. Furthermore, current management practice of SCAD is based mainly on retrospective data and case series and clear management guidelines are lacking. In this article, we present a series of cases of patients with SCAD and we will discuss the different clinical presentations, the diagnostic approaches and the options of management of this cohort of patients...

Iatrogenic aortic dissection is an infrequent complication of cardiac catheterization (0.03-0.06%) associated with up to 19% of mortality at 30 days. It was reported to mostly occur when using a 6-Fr guiding catheter to cannulate the right coronary artery. This life-threatening complication usually requires early surgical management and close imaging monitoring and control of systolic blood pressure. This case report describes a patient with iatrogenic aortic dissection during cardiac catheterization in symptomatic coronary artery disease...

OBJECTIVES: Failure of mechanical conventional ventilation (MCV) after cardiac surgery portends a dismal prognosis, with extracorporeal membrane oxygenation frequently utilized as a salvage therapy. We describe our experience with high-frequency percussive ventilation (HFPV) as a rescue therapy for hypoxaemia refractory to MCV after cardiac surgery. METHODS: In a 6-year retrospective analysis from 2009 to 2015, we identified 16 subjects who required HFPV after cardiac surgery...

RATIONALE: Thin-cap fibroatheroma (TCFA) and red thrombus are suggested as a high-risk of embolic complications during percutaneous coronary intervention (PCI). Intracoronary aspiration procedures occasionally result in either an insufficient thrombus removal or provide no significant effects on TCFA. PATIENT CONCERNS: A 76-year-old male underwent coronary angiography for chest pain. DIAGNOSES: Coronary angiography revealed a tight stenosis at the right coronary artery which resulted in treatment by PCI...
