We report a 63-year-old female with hypertension, hyperlipidemia, and prior pacemaker insertion for atrial fibrillation with symptomatic bradycardia, who was admitted with substernal chest pressure and diaphoresis. Her electrocardiogram revealed atrial fibrillation with demand ventricular pacing and her cardiac biomarkers were negative for acute coronary syndrome. Echocardiogram revealed normal left ventricular systolic function and normal aortic root diameter. Coronary angiography revealed 60-70% obtuse marginal lesion, otherwise mild disease...

Atrial fibrillation (AF) is leading cardiac arrhythmia with important clinical implications. Its diagnosis is usually made on the basis on 12-lead ECG or 24-hour Holter monitoring. More and more clinical evidence supports diagnostic use of cardiac event recorders and cardiovascular implantable electronic devices (CIED). Treatment options in patients with atrial fibrillation are extensive and are based on chosen rhythm and/or rate control strategy. The use and selected contraindications to AF related pharmacotherapy, including anticoagulants are shown...

We report an 84-year-old woman who presented with right ventricular perforation 4 days after pacemaker implantation for syncope due to sick sinus syndrome. Median sternotomy revealed no pericardial effusion, but the pacing lead had penetrated the right ventricle and pericardium. When the pleura was opened, the tip of the lead was seen in the visceral pleura. The lead was cut in the pericardial cavity and extracted from the left subclavian wound together with the generator. The right ventricular perforation was sutured and a temporary pacing lead was placed on the right ventricular wall intraoperatively...

There has been an increase in superior vena cava (SVC) syndrome secondary to the growinguse of indwelling catheters and pacemaker wire insertions. These two factors can account up to 74 % cases of benign SVC syndrome. Endovascular therapy is considered the first line of treatment. Surgery is an excellent option and is generally reserved for SVC syndrome not amenable to traditional endovascular procedures. We report a case of central venous reconstruction including an SVC reconstruction using the femorpopliteal vein (FPV) as a panel graft in a patient with SVC syndrome due to pacemaker wires who failed multiple endovascular interventions...

SUMMARY: Cushing's syndrome is associated with increased morbidity and mortality. Although surgery is the first-line treatment, drugs can still play a role as an ancillary treatment to be employed while waiting for surgery, after unsuccessful operation or in patients unsuitable for surgery. We were asked to evaluate a 32-year-old male waiting for cardiac transplantation. Idiopathic hypokinetic cardiomyopathy had been diagnosed since 6 years. He was on treatment with multiple drugs, had a pacemaker, an implantable cardioverter and an external device for the support of systolic function...

BACKGROUND: There are limited clinical records in the literature regarding aortic valve replacement in left ventricular assist device (L-VAD) patients. Previously we had two cases of severe aortic valve regurgitation in patients with L-VAD support treated with Corvalve prosthesis insertion and Amplatzer closure procedure. Both patients died a few days after the procedure from complications not related to the procedure itself. PATIENT HISTORY: The patient was a male with previous coronary artery bypass graft surgery in 2001 that was complicated with postischemic dilated cardiomyopathy with severe heart failure (ejection fraction [EF], 20%)...

BACKGROUND: Minimally invasive aortic valve replacement (MAVR) has demonstrated a benefit with respect to increased patient satisfaction due to minimised pain and earlier recovery. Sutureless valves may benefit MAVR and conventional aortic valve replacement (AVR) by reducing operative times and blood transfusion requirements. The Perceval valve (Sorin, Salluggia, Italy) is a self-expanding prosthesis made from bovine pericardium mounted in a nitinol stent, designed to simplify the implantation of an aortic valve...
