Live three-dimensional echocardiography of the human fetus.

The purpose of this study was to investigate the feasibility of using a new three‐dimensional ultrasound system to perform fetal echocardiographic examination in real time. The device consisted of a Philips Sonos 7500 (Andover, MA) ultrasound system and a 4 MHz, 4X matrix transducer. The study was approved by the Institutional Review Board and was performed with the informed consent of the mother. The study population consisted of 12 singleton fetuses with gestational ages of 16–37 weeks. Of these, ten fetuses had normal cardiac anatomy, one had complete atrioventricular septal defect, and the other a thickened tricuspid valve. The system allowed comprehensive visualization of fetal cardiac anatomy and color Doppler flow unattainable by two‐dimensional approaches. This preliminary investigation suggests that live three‐dimensional fetal echocardiography could be a significant tool for prenatal diagnosis and assessment of congenital heart disease in the human fetus.

Live Three-Dimensional Transthoracic Echocardiographic Delineation of Patent Ductus Arteriosus

We report an adult patient with a patent ductus arteriosus in whom live three‐dimensional transthoracic echocardiography provided comprehensive assessment of the morphology and pathophysiology of the lesion. (ECHOCARDIOGRAPHY, Volume 21, July 2004)

Surviving ventricular standstill for 111 seconds during Holter monitoring.

Holter electrocardiogram recording revealed symptomatic prolonged ventricular standstill lasting for about two minutes which terminated without any external cardiopulmonary resuscitation.

Transesophageal echocardiographic diagnosis of aortic arch-left innominate vein fistula.

We present a patient with aortic arch–left innominate vein (LIV) fistula diagnosed by transesophageal echocardiography. Also, an interrupted linear echo was noted within the dilated LIV with flow signals moving across the area of interruption, suggestive of left innominate vein pseudo‐aneurysm or dissection. The patient subsequently underwent successful surgical repair of the fistula.

Acute Bioprosthetic Mitral Valve Stenosis in a Patient with HITS

Abstract  Acute thrombosis involving the left atrium and a bioprosthetic valve during the early postoperative period is an extremely rare complication of heparin‐induced thrombocytopenia syndrome (HITS). We present a patient with early bioprosthetic mitral valve stenosis complicated by HITS in a patient with severe mitral regurgitation, atrial fibrillation, and severe left ventricular dysfunction. (J Card Surg 2011;26:369‐371)

Surgical Correction of Congenital Heart Disease at 76 Years of Age

Abstract  The management of adult congenital heart disease is challenging and poses specific problems. We report a patient with ventricular septal defect and pulmonary stenosis who underwent successful repair and coronary artery bypass grafting at the age of 76 years. (J Card Surg 2010;25:672‐674)

Cardiac gunshot injury: Child with stable presentation and asymptomatic short-term follow-up

A 2‐year‐old female child was brought to the emergency department after she was accidentally shot by her father, while cleaning his air rifle loaded with the pointed type 0.22 (5.5 mm) caliber pellet. The pellet hit the front of chest from a distance of about 10–15 m. On physical examination, it was found that there was entrance wound in right lower parasternal area but no exit wound. She was hemodynamically stable with normal auscultatory findings. Chest roentgenogram ( Fig. 1 ) demonstrated a bullet overlying cardiac silhouette with no other findings. Two‐dimensional transthoracic echocardiography ( Figs, 2, 3 , and movie clip 1) showed an echogenic density in the interventricular septum just beneath the insertion of tricuspid and mitral leaflets. The atrioventricular valves appear normal with no regurgitation. The biventricular function also appeared normal with no regional wall motion abnormalities. There was no pericardial effusion present. The echogenicity is most likely the pellet that punctured the chest wall and continued inward to lodge in the interventricular septum. Computed tomographic scan of the chest showed an intracardiac foreign body without other abnormalities. Up to 11 months, repeated scans have shown no changes. She will continue to receive ongoing follow‐up to assess for late complications (migration, erosion, conduction, disturbance, etc.) To the best of our knowledge, she may be the youngest living patient having cardiac trauma with clinically stable presentation and asymptomatic short‐term follow‐up.
