Noninvasive graphic evaluation: phonocardiography and echocardiography.

Noninvasive graphic techniques are an invaluable tool in the diagnosis, management, and followup of patients with valvular heart disease. They are both sensitive and specific and therefore often eliminate the need for more invasive and more expensive diagnostic procedures. When cardiac catheterization and/or cineangiography are necessary to obtain definitive hemodynamic or anatomic information, prior noninvasive graphic evaluation frequently directs the cardiologist to the appropriate type of study to be performed. This is especially true of subtle tricuspid valvular disease, unsuspected silent stenotic valvular lesions, or unusual causes of aortic regurgitation. Because these studies are noninvasive and can be repeated as often as necessary, they are ideal techniques for the longitudinal followup of the patient. Additionally, these techniques are excellent teaching tools, and they allow cardiologists to continually check and refine their clinical skills, which are the foundation of the bedside evaluation of the patient with valvular heart disease.

Carcinoid heart disease: diagnosis by two-dimensional echocardiography.

We prospectively studied 14 patients with the carcinoid syndrome to determine if two-dimensional echocardiography could detect the nature and extent of valvular abnormalities. Eight of the 14 patients had definite abnormalities of the right-sided cardiac valves. The tricuspid valve had a characteristic appearance, similar to previously described pathologic findings. The leaflets appeared diffusely thickened, shortened and stiff without evidence of commissural fusion. Saline contrast studies demonstrated tricuspid regurgitation, which corresponded to the severity of the tricuspid valve involvement. The pulmonary valve could only be adequately assessed in seven of 14 patients, and morphologic abnormalities similar to those in the tricuspid valve were found. Follow-up studies have shown progression of cardiac disease in six of eight patients. We conclude that two-dimensional echocardiography can detect the characteristic cardiac abnormalities in the carcinoid syndrome and may be a useful tool for following their progression.

Versatility of Inoue balloon catheter.

Inoue rubber nylon single balloon catheter is being used worldwide for performing balloon mitral valvuloplasty (BMV). The popularity of Inoue balloon is attributed to its self-positioning configuration, size-adjustability, rapid inflation-deflation sequence and the ease of performance. We report its use in performing various non-mitral interventions. Its utility in treating patients with mitral stenosis and combined mitral and tricuspid stenosis is well established. Seventeen patients with valvular pulmonic stenosis (age 32+/-16 years; 11 males and 6 females) achieved significant reduction of peak systolic gradient (PSG) from 125+/-28 to 32+/-16 mmHg (P<0.005). Four patients with inferior vena-cava obstruction (age 20-48 years; 3 males and 1 female) derived symptomatic benefit following successful dilatation. Inoue balloon was used to create percutaneous pericardial window in four cases (age 43-68 years; 2 males and 2 females) of recurrent pericardial collection secondary to carcinoma lung/breast, thus alleviating the symptoms of tamponade. One patient each with coarctation of aorta (32 years, male), discrete subaortic membrane (16 years, female), and critical valvular aortic stenosis (13 years, male) derived immediate hemodynamic improvement with Inoue balloon dilatation. No major complications were encountered. We conclude that Inoue balloon can be used to successfully manage various stenotic lesions.
