Longitudinal stent deformation, described in some older stent geometries, prompted design modifications such as reinforcing struts on the proximal end. However, distal edges of stents-also subject to longitudinal force-have not been reinforced. We report a case of guidewire entrapment that deformed the distal edge of a new-generation stent during percutaneous coronary intervention, and we describe our efforts to restore the stent to its initial length. This case highlights the risk of manipulating equipment beyond the position of a newly deployed stent, the ongoing potential for deformation of distal edges in newer stent platforms, and the advisability of treating distal lesions before proximal ones...

Methamphetamine abuse is an increasingly prevalent cause of pulmonary artery hypertension in the United States. Conversely, an atrial septal defect rarely presents late as pulmonary artery hypertension. We present the case of a 44-year-old methamphetamine abuser who had a 3-month history of worsening fatigue and near-syncope. She had elevated cardiac enzyme levels and right-sided heart strain. Angiographic findings suggested methamphetamine-induced pulmonary artery hypertension; however, we later heard S2 irregularities that raised suspicion of an atrial septal defect...

Direct-current cardioversion is an important means of managing arrhythmias. During treatment, carefully synchronizing energy delivery to the QRS complex is necessary to avoid ventricular fibrillation caused by a shock during the vulnerable period of ventricular repolarization, that is, a shock on the T wave. The presence of an accessory pathway and ventricular preexcitation can lead to difficulty in distinguishing the QRS complex from the T wave because of bizarre, wide, irregular QRS complexes and prominent repolarization...

Mesenteric ischemia can be difficult to diagnose without a high degree of suspicion because it presents in a variety of ways. Visceral vascular collaterals between the fore- and midgut often provide protection against ischemia; however, the presence of anatomic variations, such as celiomesenteric trunk, can undermine the expected redundancy. Misdiagnosis can result in prolonged suffering or death, as evidenced in 2 of our patients with celiomesenteric trunk. The first patient with chronic mesenteric ischemia was diagnosed in the clinic and underwent successful surgical correction; the other had overwhelming, acute mesenteric ischemia, which resulted in death...

We report the case of a 44-year-old pregnant woman who was diagnosed with symptomatic severe mitral stenosis that did not respond to optimal medical therapy and balloon valvuloplasty. After a multidisciplinary team discussion on the timing and risks of interventions and postoperative optimization of peripartum anticoagulation, the patient underwent mechanical mitral valve replacement during the 2nd trimester of pregnancy. The outcome was excellent for the mother and the infant. This case emphasizes the importance of a multidisciplinary approach in managing unusual cases...

Nonischemic dilated cardiomyopathy is deadly and costly, and treatment options are limited. Cardiac rehabilitation has proved safe and beneficial for adults with various types of heart failure. Therefore, we retrospectively evaluated the hypothesis that rehabilitation is safe and improves cardiometabolic health in young patients with nonischemic dilated cardiomypathy. From 2011 through 2015, 8 patients (4 males) (mean age, 20.6 ± 6.6 yr; range, 10-31 yr) underwent rehabilitation at our institution. They were in American Heart Association class C or D heart failure and were on maximal medical therapy...

December 2017 was the 230th anniversary of Jan Evangelista Purkinje's birth, which prompted us to review the life of this remarkable man who established the world's first department of physiology in Wroclaw and whose name is immortalized in the cardiologic eponym, Purkinje fibers. This paper offers an overview of Purkinje's life, legacy, and numerous scientific discoveries.

Using older donor hearts in cardiac transplantation may lead to inferior outcomes: older donors have more comorbidities that reduce graft quality, including coronary artery disease, hypertension, diabetes mellitus, and dyslipidemia. Shorter cold ischemic times might overcome the detrimental effect of older donor age. We examined the relationship between donor allograft age and cold ischemic time on the long-term outcomes of heart transplant recipients. rom 1994 through 2010, surgeons at our hospital performed 745 heart transplantations...

In elderly, high-risk surgical patients, sutureless aortic valve replacement (AVR) can often be an alternative to conventional AVR; shorter aortic cross-clamp and cardiopulmonary bypass times are the chief advantages. We compared the outcomes of sutureless AVR with those of conventional AVR in 70 elderly patients who underwent concomitant cardiac surgical procedures. We retrospectively analyzed the cases of 42 men and 28 women (mean age, 70.4 ± 10.3 yr; range, 34-93 yr) who underwent cardiac operations plus AVR with either a sutureless valve (group 1, n=38) or a conventional bioprosthetic or mechanical valve (group 2, n=32)...

A major diagnostic challenge for cardiologists is to distinguish cardiac syndrome X (CSX) from obstructive coronary artery disease in women with typical angina and a positive exercise tolerance test (ETT). We performed this study to develop a scoring system that more accurately predicts CSX in this patient population. Data on 976 women with typical angina and a positive ETT who underwent coronary angiography at our center were randomly divided into derivation and validation datasets. We developed a backward stepwise logistic regression model that predicted the presence of CSX, and a scoring system was derived from it...
