Electrocardiographic changes with right-sided pneumothorax.

Pneumothorax is a well-known complication of central line placement in the intensive care unit. Other causes include spontaneous pneumothorax, trauma, and infection. Most frequently, dyspnea or respiratory decompensation raises suspicion for pneumothorax, especially after central line placement. The diagnosis is confirmed by physical examination and chest radiography. We present five cases of right-sided pneumothorax in which electrocardiographic findings resolved with reexpansion of the lung. A new finding is reported in two cases.

Familial occurrence of mitral valve prolapse in X-linked muscular dystrophy.

A high incidence of mitral valve prolapse (MVP) has been reported in patients with X-linked Duchenne muscular dystrophy. In our study MVP was present in six of 22 Duchenne dystrophy cases (27%) followed in the Maryland General Hospital Muscular Dystrophy Clinic. In addition, seven carriers of Duchenne and X-linked benign (Becker) dystrophy had evidence of MVP. Autosomal dominant transmission of MVP was present in four families. The unusually high prevalence of MVP in families with X-linked muscular dystrophy may have potential value in the recognition of the carrier trait.

The challenges of cardiac pacing: an illustrative case.

The history of transvenous pacing encompasses the past five decades. Multiple lead complications have been described, including problems related to central venous access, venous thrombosis, extravascular bleeding, lead and pacemaker pocket infections, lead fractures, lead dislodgment, lead perforation, diaphragmatic pacing, and chronic lead threshold changes. Potential solutions to these problems have included: improvements in lead composition and tip technology, multiple pacemaker lead and generator insertions, alternative lead sites, pacemaker lead extenders, extraction of infected leads, multiprogrammable pacemaker generators, high output generators, antibiotics and anticoagulants, and venous reconstruction. This case illustrates complications and solutions over a 20-year period. The indications for temporary transfemoral and permanent iliac vein transvenous pacing are reviewed, including a new indication for the iliac venous approach.
