A 59-year-old female patient with breast cancer (ductal carcinoma in situ ), treated with chemotherapy, radiation therapy and hormone therapy as relevant past medical history. During follow-up in oncology consultation, the patient presented cough and underwent a chest X-ray and thoracic computed tomography that revealed a fracture and embolization of intravascular portion of central venous catheter to the right pulmonary artery (Figures 1A and 1B). The patient was referred to cardiac catheterization lab for percutaneous removal of the intravascular portion […]

An 11-year-old male patient with a clinical history of psychomotor development delay and ventricular preexcitation required several follow-up visits at another service. No other cardiovascular-associated symptoms were described. Since the family moved home, the child was referred to our hospital. A transthoracic echocardiogram (TTE) was performed as part of standard evaluation in the first appointment, revealing anatomical changes of the coronary arteries. Further investigation included cardiac computed tomography (CT) which showed multiple aneurysmal dilations along the path of the right […]

A 69-year-old patient with history of heart transplant in 2018 due to Chaga’s disease underwent a 2-years control myocardial perfusion imaging scintigraphy, which demonstrated minor stress-induced apical ischemia. He was asymptomatic, and his last endomyocardial biopsy was 2 years ago, with no history of graft rejection. After the scintigraphy finding of ischemia, a coronary angiography was performed, which displayed a fistula between the left anterior descending artery and right ventricle with subsequent coronary occlusion (). This is a rare complication […]

A 47-year-old woman was referred for transcatheter closure of a secundum atrial septal defect (ASD). Vascular access was obtained via the right femoral vein and 16-mm ASD diameter was determined using balloon and the stop-flow sizing technique (). […]

A 67-year-old man with several cardiovascular risk factors was referred to cardiology consultation, due to effort angina – Canadian Cardiology Society (CCS) class II/IV, for the last 6 months, under optimal medical treatment. Resting electrocardiogram and transthoracic echocardiogram (TTE) were normal. Stress treadmill test was positive. The coronary angiogram revealed a long proximal chronic total occlusion (CTO) of the left anterior descending artery (LAD; J-CTO=1, Rentrop3), a distal CTO of the left circumflex artery (J-CTO=0, Rentrop3) and a 50% stenosis […]

A 69-year-old male with hypertension, dyslipidemia, and coronary artery disease (CAD) was admitted to the emergency room in December 2020 reporting chronic angina, with slight limitation to ordinary activities (Canadian Cardiovascular Society angina grade II) and described worsening of symptoms in the past 20 days, with episodes of prolonged angina (over 20 minutes) and mild dyspnea. An initial 12-lead electrocardiogram showed no signs of acute ischemia, and the cardiac biomarkers were negative for myocardial infarction (troponin 9ng/L; upper limit of […]

A 61-year-old female patient was referred to the cardiology department for dyspnea upon exertion. A transthoracic echocardiogram showed a severely stenotic bicuspid aortic valve and normal ejection fraction in both ventricles. She was submitted to a routine preoperative coronary angiography. A right radial access was obtained. Despite numerous efforts, it was not possible to visualize the origin of the left main coronary artery at the left ostium. Catheterization of right coronary artery was done and demonstrated a normal implantation at […]

We present two cases of single coronary artery (SCA), an extremely rare congenital anomaly, in which only one artery arises from the aortic arch by a single coronary ostium, supplying the entire heart. This condition occurs only in 0.024% to 0.044% of population, and most cases are associated with other congenital anomalies, such as persistent ductus arteriosus, tetralogy of Fallot and pulmonary atresia. In a 2-week period, the two patients presented at the emergency department with non-ST segment elevation acute […]

Transcatheter mitral valve repair (TMVR) using the MitraClip® system is an emerging approach to treat selected cases of degenerative and functional mitral regurgitation (MR). Patients referred for MitraClip® implantation often have concomitant atrial fibrillation (AF), in addition to a frailty profile that represents an increased risk of thromboembolic and hemorrhagic events. Occlusion of the left atrial appendage (LAA) is currently considered an alternative for oral anticoagulation in patients with non-valvular AF. We describe here a combined implantation using the MitraClip® […]

Coarctation of the aorta (CoA) accounts for 5% to 7% of all congenital heart disea­ses, with an estimated incidence of approximately three cases per 10 thousand live births. CoA treatment is indicated when the coarctation gradient is equal to or greater than 20mmHg., Without treatment, the prognosis is poor, with 75% mortality at 43 years of age. The use of stents for endovascular treatment of CoA was first reported in 1991, expanding the possibilities of transcatheter treatment. Retrospective analyses show […]
