Left fouratrial heart. First clinical case

[Heart transplantation for the treatment of isolated left ventricular myocardial noncompaction. First case in Mexico].

BACKGROUND Myocardial noncompaction of the left ventricle is a congenital cardiomyopathy characterised by left ventricular hypertrabeculation and prominent intertrabecular recesses. The incidence ranges from 0.15% to 2.2%. Clinical manifestations include heart failure, arrhythmias, and stroke. Prognosis is fatal in most cases. Heart transplantation is a therapeutic option for this cardiomyopath...

left-sided angiosarcoma of heart: a rare case

a 22-year-old man presented with exertional dyspnea commencing one month prior to his admission. echocardiography revealed a non-homogenous mass, and the pathology examination of the pericardial biopsy was compatible with angiosarcoma.

The loud first heart sound in left atrial myxoma.

The interrelation between the loudness of the first heart sound, the time interval from the Q wave to the onset of the first heart sound (QM1), and the mitral valve closure rate was studied in nine patients presenting with left atrial myxomata. In seven patients the first heart sound was loud preoperatively and was associated with delayed mitral valve closure. After removal of the myxoma the on...

Preserved Left Ventricular, Systolic Function in Clinical Congestive Heart Failure

CLINICAL PROGRESS Retrograde Arterial Catheterization of the Left Heart

HISTORICALLY, retrograde catheterization of the arterial circulation appears to have been the first method employed in the study of the left heart. Cournand1 cites the physiologic studies of Chauveau and Marey. They recorded pressure tracings obtained from the left ventricle of the erect, unanesthetized horse in 1861.2 3 Almost 100 years later, in 1950, three groups of workers reported applicat...
